The Hottest Questions About Led Light

Considering that led light may still be new to many people, we provide ten common questions and answers about led light for you to get started.

1. when a led light bulb glass breakes?

problematic subject. query using yahoo or google. that might help!

2. How do you turn off the LED light next to the webcam in an HP entertainment notebook?

It skill that the Theftlock II gadget built into the producing facility radio is lively. Theftlock is a GM anti-theft gadget that locks the radio applications if that's utilized in a various vehicle than the single wherein it replaced into initially put in. The gadget on your radio is progressed sufficient that it may study the vehicle's VIN for the duration of the suggestions bus gadget. meaning it would paintings effective on your vehicle, whether you lose battery skill for a whilst, yet wo not paintings in the different vehicle till that's reset via a GM broking. in short, it is not something you will could be hectic approximately till you p.c. to circulate your production facility radio right into a various vehicle.

3. Does an LED light bulb convert AC to DC?

I assume by bulb you mean a 110 to 240VAC mains rated light.Many of these lights contain a current source power supply consisting of a full wave bridge rectifier and an integrated circuit containing a power MOSFET for handling the power switching. Typically these look like those found in the ic device bp2832a data sheet (do a Google search).

4. Safety practices for 5-volt 150-watt power supply for dot-programmable RGB LED light ribbons

Unfortunately, enclosures are tricky when the equipment needs to be ventilated. The first rule of electrical is that anything that touches mains power must have a proper UL listing, CSA, ETL or equivalent. US-OSHA keeps a list, and everyone else dogpiles on and cites it rather than maintain their own list. Your tax dollars at work. A RU listing (UL component listing) is not that. RU component listings shortcut a UL equipment listing because the component is pre-certified. And CE is definitely not that; it is a junk mark gleefully faked by the Chinese. The rare Chinese maker who is able to stick a UL listing on their item proudly does, with file number, and they do not use CE at all; no need to fake. I do not know the Canadian code requirement for approved (read: CSA-approved) items, but the NEC section is 110.2. It's on the first page. I have excellent 24V GE power supplies for LED lighting that mount in a fluorescent ballast form-factor. Still need enclosures, but designed to play in a confined space. The go-to in the "Chinese, but UL listed" department is Meanwell, and their stuff is sold at Mouser, Digi-Key, the usual. Some of their supplies have the UL or ETL listing instead of the component-level RU mark. There is no Code legal way to bring hot and neutral to open, uncovered screw terminals on the equipment. That is one of the 100 details that the Chinese fakirs completely ignore in Code. This might be allowed in an RU component. I suspect on the UL-listed Meanwell supplies, they will have an IEC inlet or a proper cover for the 120V splice areas. Another important thing required in mains code is complete separation of mains and low voltage power. Bringing them onto the same terminal block is a nope.

5. on my hp pavilion dv7-6143cl laptop led light on touchpad is not on?

try fn space. you want the back light to come back on right?

6. How "bright" are 2 "bulb" LED light fixtures in a garage?

Depends on the lumen output of the LED bulbs you are considering. I will tell you this: LED lights are considerably brighter than the standard fluorescent bulb

7. How much energy does an LED light bulb produce?

It depends on what kind u brought

8. can one use a dusk till dawn switch with a led light bulb?

Oh yeah, and probably one of the most fun nights I've had. Drinking and going to the club down in Myrtle Beach, SC. Under age at the time so that's what made it more exciting, and ran into these girls from Ireland on a foreign exchange student/work visa. Partied and danced with them all night long till the place shut down, then we took the party to their hotel(if you catch my drift). Continued to drink, and went swimming in the ocean. All this lasted till about 8 in the morning. Needles to say, a fun night/morning.

Explain the Key Points of LED Lighting Driving Power Supply in Detail
In order to save energy and power, LED has been greatly promoted, but led needs a power driver, which will directly affect the service life of LED. Therefore, how to do a good LED driving power supply is the top priority of LED power designer. This paper introduces some problems of LED driving power supply, hoping to provide some help to engineers.1. The driving circuit directly affects the service life of LEDThe LED driver we mentioned includes digital driver and analog driver. Digital driver refers to digital circuit driver, including digital dimming control, RGB full-color change, etc. Analog drive refers to analog circuit drive, including AC constant current switching power supply and DC constant current control circuit. The driving circuit is composed of electronic components, including semiconductor components, resistance, capacitance, inductance, etc. these components have service life. The failure of any device will lead to the failure of the whole circuit or some functions. The service life of LED is 50000-100000 hours. If it is continuously lit according to 50000 hours, it has a service life of nearly 6 years. The service life of switching power supply is difficult to reach 6 years. The warranty period of switching power supply sold on the market is generally 2-3 years. The power supply with 6-year warranty is military grade, and the price is 4-6 times that of ordinary power supply. It is difficult for ordinary lamp manufacturers to accept it. Therefore, the faults of LED lamps are mostly driving circuit faults.2. Heat dissipation problemLED is a cold light source, the working junction temperature cannot exceed the limit, and a certain margin should be reserved during design. The design of the whole lamp should consider many aspects, such as beautiful appearance, convenient installation, light distribution, heat dissipation and so on. It is necessary to find a balance point among many factors, so that the overall lamp is the best. The development time of LED lamps is not long, there is not much experience to learn from, and many designs are constantly improved. The power supply used by some LED lamp manufacturers is outsourced or purchased. The lamp designer does not know much about the power supply, so the heat dissipation space for LED is large and that for power supply is small. It is generally to find a suitable power supply after designing the lamps, which brings some difficulty to the power supply. It is often encountered that due to the small internal space or high internal temperature of the lamp, and the low cost control, it is impossible to allocate a suitable power supply. Some LED lamp manufacturers have power R & D capability. The above problems can be solved by evaluating at the initial stage of designing lamps and designing power supply synchronously. In the design, we should comprehensively consider the heat dissipation of LED and power supply, and control the temperature rise of lamps as a whole, so as to design better lamps.3. Problems in power supply designa. Power design. Although the LED has high luminous efficiency, there is still 80-85% heat loss, resulting in a temperature rise of 20-30 degrees inside the lamp. If the room temperature is 25 degrees, there is 45-55 degrees inside the lamp. The power supply works in a high-temperature environment for a long time. In order to ensure the service life, the power margin must be increased, which is generally reserved to 1.5-2 times.b. Component selection. When the internal temperature of the lamp is 45-55 degrees, the internal temperature rise of the power supply is about 20 degrees, and the temperature near the element should reach 65-75 degrees. The parameters of some components will drift at high temperature, and the service life of some components will be shortened. Therefore, the devices should be selected that can be used at high temperature for a long time, with special attention to electrolytic capacitors and wires.C. Electrical performance design. The parameter design of switching power supply for LED is mainly constant current parameter. The size of current determines the brightness of LED. If the batch current error is large, the brightness of the whole batch of lamps is uneven. Moreover, the change of temperature can also cause the output current of the power supply to shift. Generally, the batch error is controlled within / - 5% to ensure the consistent brightness of the lamp. There is deviation in the forward voltage drop of the LED, and the constant current voltage range of the power supply design should include the voltage range of the LED. When multiple LEDs are connected in series, the minimum voltage drop multiplied by the number of connected in series is the lower limit voltage, and the maximum voltage drop multiplied by the number of connected in series is the upper limit voltage. The constant current voltage range of the power supply is slightly wider than this range. Generally, 1-2v margin is reserved for the upper and lower limits.d. PCB layout design. The size of LED lamps left for the power supply is small (unless it is external to the power supply), so there are high requirements in PCB design and many factors to be considered. Enough safety distance shall be reserved for the power supply requiring input and output isolation. The withstand voltage of primary side circuit and secondary side circuit shall be 1500-2000vac, and at least 3mm distance shall be reserved on the PCB. If it is a lamp with metal shell, the safety distance between the high-voltage part and the shell shall also be considered for the cloth plate of the whole power supply. If there is no space to ensure a safe distance, other measures should be taken to ensure insulation, such as drilling holes on PCB, adding insulating paper, potting insulating glue, etc. In addition, the heat balance shall be considered for the cloth plate, and the heating elements shall be evenly distributed and cannot be placed centrally to avoid local temperature rise. The electrolytic capacitor is far away from the heat source to slow down the aging and prolong the service life.e. Certification issues. At present, there is no standard for LED lamps in China. Relevant national departments are studying and formulating. The certification of lamps sold in China is based on the standards of lighting lamps, while those sold abroad are CE or UL certification, and some are based on foreign LED lamp standards. Therefore, in view of this situation, it is difficult for the design of switching power supply to meet the above standards at the same time. We can only meet different certification according to different requirements.4. Use parameters.The selection of purchased power supply mainly depends on the voltage range of constant current and constant current. The constant current value is lower than the standard current of LED. The selection of voltage range shall be moderate, and try not to select a large range to avoid power waste.
Why Are LEDs so Popular? Discussion on Connector of LED Lighting Standard
Light emitting diodes (LEDs) have revolutionized indoor and outdoor lighting. This solid-state lighting (SSL) technology has excellent efficiency, controllability, chromatography, thermal performance and unique shape. It is eliminating the ancient Edison incandescent bulbs (as well as fluorescent lamps, metal halide lamps or sodium vapor lamps). Now, most new indoor and outdoor designs and upgrading of existing designs will first consider led. However, designers should be careful. At the same time of rapid innovation, there will also be some hidden dangers, such as non-standard connection and end-user solution mismatch, which will cause a negative customer experience.It is not just the light source itself that has been completely changed. For example, LED lighting is also changing the design and shape of connectors and their fixtures (called lamps). These connectors are an essential part of any lighting system. They do not accept AC line voltage, but lower DC voltage. The typical current is usually between 3 A and 7 a. In addition, LED lighting system is usually part of the control network supporting digital addressable lighting interface (DALI) and zhaga industry standard, and provides intelligent, energy-saving and high-performance lighting as a key link of smart home or office.Therefore, before designing LED lighting system, engineers have the responsibility to be familiar with these standards and their reflection in real-world connectors, because new designs are rising rapidly.This paper briefly reviews why LEDs are so popular, and then introduces and describes these two connection standards to ensure interoperability, rapid development and easy deployment of intelligent LED design. Finally, the connectors of Amphenol ICC are introduced, and as the practical embodiment of relevant standards and their applications, the application of these connectors is summarized.Why are LEDs so popularThere are many factors promoting the development of led into lighting source:Cost reduction promotes the increase of output, which further promotes the reduction of cost and the increase of outputBasic reliability and life enhancement of LED as light sourceThe improvement of the circuit is mainly the improvement of the power supply driving these LEDsImprovement of optical output quality characterized by color temperature (Kelvin) and color rendering index (CRI)Incentives, standards and enforcement measures taken by the government to improve lighting efficiency to save energy (it is estimated that lighting accounts for 15% to 20% of total energy consumption)Development of industry and government standards that ensure interoperability between LED light sources and compatibility with intelligent controllers.The last point is particularly important. An important size category of traditional incandescent bulbs is the "E26" 26 mm (mm) diameter Edison screw bulb, which is almost commonly used in residential environments in the United States and many other countries (Figure 1). It is being replaced by LED and fluorescent bulbs, but to a lesser extent. Of course, there are other sizes, such as E12 base, but E26 is the most widely used at present.Of course, standardizing to a single base and socket can reduce costs. The same technology has also led to a variety of bulb shapes, power levels and other attributes built around this foundation, while reducing concerns about long-term replacement of burned bulbs. Early generations of LED bulbs used E26 base to be compatible with existing sockets, making users accustomed to LED lighting. These E26 LED bulbs are still widely sold because there are countless such sockets in use, so the replacement process will take a long time.However, compared with incandescent lamps, LEDs are very different in current, voltage (DC) and power consumption. Incandescent bulbs usually use 120 / 240 V AC power supply. In addition, the wire of E26 socket often has relatively large threaded terminals, which is not ideal for LED light source power supply (Fig. 2). Therefore, new standards and connector types are needed in order for LEDs to give full play to their potential from the system level to the physical connection level.Recognizing the needs of modern lighting interface standards, the Digital Lighting Interface Alliance (diia) developed the Dali standard.The Dali standard redefines lighting connectionsDali is a special protocol for digital lighting control, which can easily realize firm, scalable and flexible lighting network installation (Figure 3). The first version dali-1 is more suitable for digital control, configuration and query of fluorescent lamp ballasts, and less led factors are considered. It replaces the simple, unidirectional and broadcast operation of the existing 0 / 1 to 10 volt analog control mode.The standard also includes a broadcast option. Through simple reconfiguration, each Dali device can be assigned a separate address, allowing digital control of a single device. In addition, Dali devices can also be programmed for grouping operation, so that the lighting system can be reconfigured through software to avoid changing wiring.With the growth of user expectations and the improvement of LED technology, the development of dali-2 standard is promoted. Dali-2 is not only an industry standard, but also a standard of the International Electrotechnical Commission (IEC 62386). Dali-2 adds many new commands and functions. Dali-1 only includes control mode, while dali-2 covers control devices, such as application controllers and input devices (such as sensors), as well as bus power supply. It focuses on the interoperability of products from different manufacturers, and is supported by dali-2 certification plan to confirm the compatibility between products and specifications (Figure 4).Like all comprehensive standards, dali-2 is complex. In short, with a single line pair as the bus, each device on the Dali network can be addressed separately. The bus is used to provide both signals and power. The supported power supply can provide up to 250 Ma at 16 V DC (typical). This standard supports equipment powered by AC lines or DC power rails.Although various standards define ultra-low voltage (ELV), IEC defines ELV equipment or circuit as: the potential difference between electrical conductor and grounding does not exceed AC 50V or DC 120V. Dali control cable is classified as ELV equipment, so it only needs to be basically insulated from AC mains power; It can be routed together with mains lines or multi-core cables including mains lines.Beyond dali-2: zhaga specification, aiming at lampsDali-2 and other standards are important, but they can only stop there. It is not within the scope of its definition to define how to link standards to specific applications, such as LED lighting and lamps. In order to solve this problem, the international zhaga alliance has formulated the interface industry specification of components used in LED lamps. The alliance is a member project of IEEE industry standards and technology organization. As of 2019, it has more than 120 members.It's time to find out the difference between lighting equipment and lamps. The term "luminaire" is used in the lighting Engineering Society (ies) lighting manual, ANSI / NEMA standards and IEC. It was added to the National Electrical Code (NEC) manual in 2002 and is officially defined as "a complete lighting unit consisting of one or more lamps and components designed to distribute light, locate and protect the lamp tube and connect the lamp tube to the power supply". Lamps include lamps and all parts directly related to the distribution, positioning and protection of lighting devices, excluding supporting parts, such as arms, ribs or rods; Fasteners for fixing lamps; Control or safety devices; Or power lead. Lamps have a variety of forms and are suitable for various occasions, from outdoor street lighting with strict functions to indoor office lighting, and even "fashionable" retail or home lighting."Lighting equipment" is not defined in NEC and generally refers to anything in the mind of the user, which may include some or all of the following elements: lamp tube (bulb), perhaps with lampshade, lamp ball, lens or diffuser, support, lamp pole or lamp accessories, and other elements.The official name of the zhaga specification is books (specification), which aims at electrical, mechanical, optical, thermal and communication interfaces and allows the interoperability of components. By following the zhaga specification, designers can ensure that users have interoperable, replaceable or repairable components, and that led lamps can be upgraded when new technologies appear after installation.Zhaga Book 18 and book 20 are particularly useful for designers who use LED lamps; The former focuses on outdoor design, while the latter is for indoor applications.Zhaga Book 18: "intelligent interface between outdoor lamps and sensing / communication modules" specifies the contents of power supply and communication. In addition, it also specifies the mechanical coordination and electrical pins of the connection system defined in version 1.0. It simplifies the addition of application modules, such as adding sensors and communication nodes to LED lamps, and ensures plug and play interoperability.Zhaga book 20: "intelligent interface between indoor lamps and sensing / communication modules" defines the intelligent interface between indoor LED lamps and sensing / communication nodes. The node is connected to the LED driver and control system, and can usually provide sensor input or realize communication between network components. Nodes can be installed and replaced on site.epilogueLED lighting has greatly changed the indoor and outdoor lighting of industry, commerce and residence. It combines energy efficiency, long life and flexibility of lamp configuration almost perfectly.Editing: hfy

They make cleaning snow off your car a distant memory, and they protect vehicles from damage caused by theft or the elements, but let's face it: parking in them can be a real bummer. Judging distances in such a tight space is not easy and sometimes leads to an oops, resulting in a scratch or worse. But you do not need to risk your car or your home, as there are numerous tools, parking sensors, and lasers on the market now to make the task a breeze. Garage parking aids are worth their weight in gold, and we've compiled a list of the most helpful products available today. Why Should You Use a Garage Parking Aid? Garage parking aids have many uses. Namely, they prevent you or your loved ones from accidentally dinging the house when parking, potentially damaging both the car and the structure. And while you might be a pro at navigating in and out, a new driver such as a teenager is far less skilled. In addition to preventing damage, garage parking aids allow you to maximize garage space, preventing one driver from overtaking the parking space of another. If each car remains in their designated zone, this also frees up space around the perimeter for easy access. Best of all, this could potentially free up space for additional storage. We've taken the guesswork out of searching for the best garage parking aids. There are several types on the market, and we've picked the best of the best for each. MAXSA Innovations Parking Mat Parking mats are a sure-fire way to keep cars in designated spots. Our favorite is the MAXSA Innovations 37358. This is a solid performer across the board, and it checked off many of our boxes, including: Now, while we love this mat, it does have downsides that might be deal-breakers for some homeowners such as: Wheel stoppers or portable curbs are great options for keeping cars on target while parking. Our top performer is the Guardian DH-PB-4 Heavy Duty Rubber Parking Curb. This tool wins in many categories for us, including: While we loved many aspects of this parking device, some were definite cons depending on your application, such as: If you would prefer your indicator to be in the air, try a LED parking signal like the PARKEZ Flashing LED Light. These are great tools for an in-your-face warning that's perfect for new drivers. While there were many upsides to this item, there were drawbacks, including: Park-Daddy Precision Garage Parking Aid Laser parking guides are another popular item with homeowners. We have two highlights in this category: the Park Daddy and Maxsa Innovations Park Right. The Park-Daddy is a great pick for those seeking a tech solution to their parking woes. It has several pros, such as: While we were impressed with this device, it does have some cons, including: MAXSA Innovations Park Right Garage Laser Park The Maxsa Innovations Park Right is a similar device that we recommend. We came up with a few runner-up products in the garage parking aid category. They range from extremely low-tech to electronic gizmos, but all fall into what I consider an affordable price range. The Home Garage Car Parking System is another tech option that we recommend. It has several pros, such as: While it had its upsides, we disliked a few things, notably: The tennis ball method is another popular pick for homeowners where a tennis ball is hung from the ceiling to brush against your windshield when your vehicle is in your desired position. If you do not trust your own handiwork, a professional version is sold by Amazon that can retract when the garage door shuts. This is a winner on many fronts because: While it is definitely praiseworthy, it is not perfect and does have some downsides like: Homeowners can opt for car door bump pads for protection, which is less of a parking aid and more of a shield. These are handy, however, and have several perks such as: These are not for every homeowner, however, and have drawbacks like: In summary, the best garage parking aid depends on your needs and your garage building layout. Some homeowners struggle with parking straight or backing out. Many city dwellers with tight garages find that their vehicle may only fit, or not block the garage door sensors, when parked as close to the wall as possible. Others may want to maximize the space in their garage. Choose the option that best suits your situation.2. Can I change the LED light that blinks in the upper right hand corner of the blackberry pearl???it's blinking because your coverage indicator is on. hit options then screen and keyboard. go down to coverage indicator and turn off3. Does an LED light bulb need a power supply?The circuitry is inside the bulb. They draw normal current. Assuming you mean the kind you would put in the same socket you would use for an incandescent or CF bulb.

Come and join Noskillsrequired channel First, you will choose your led bulb start by buying a cheap one and take off the plastic cap think you are repairing this led bulb.We gonna proceed to the dismantling of the 220v led bulb.Very easy you have to remove first the plastic capthat is glued to the body of the led then desolder the end connectors to the mains socketand you will have the following parts:led chips connected with 2 wires to the driverand this is it nothing complicated.All led light bulbs are different so different drivers and led voltage all over.In future, you can use the driver for similar ledYou can see in the pictures real-time 220v led bulb driver not complicated some capacitors and resistor and a bridge rectifier.You can use this on future led.This one in particular outputs 220v no load and 130v loaded with the leads.So we can make in the future video an inverter dc-dc that can output 220v or 130v and we can drive this bulbs from 12v -3.7v or even a 1.5v battery.An LED lamp is an electric light or light bulb for use in lighting fixtures that produce light using light-emitting diodes (LEDs). LED lamps have a lifespan and electrical efficiency which are several times greater than incandescent lamps, and are significantly more efficient than most fluorescent lampsLike incandescent lamps and unlike most fluorescent lamps (e.g. tubes and compact fluorescent lampsor CFLs), LEDs come to full brightness without the need for a warm-up time; the life of fluorescent lighting is also reduced by frequent switching on and off. The initial cost of LED is usually higher. Degradation of LED die and packaging materials reduces light output to some extent over time.Some LED lamps are made to be a directly compatible drop-in replacement for incandescent or fluorescent lamps. An LED lamp packaging may show the lumen output, power consumption in watts, color temperature in kelvins or description (e.g. "warm white"), operating temperature range, and sometimes the equivalent wattage of an incandescent lamp of similar luminous output.To make our power supply we can just use 20-30 9v battery in seriesbecause these small batteries have those special connectors that can be connected oneonevery easy we can make a power supply that output as much volts as we want just adding a battery or taking ofif it is too much.LED driversare the essential components of LED lamps or luminaries. A good LED driver can guarantee a long life for an LED system and provide additional features such as dimming and control. The LED drivers can be put inside lamp or luminaire, which is called a built-in type or be put outside, which is called an independent type. According to different applications, different types of LED drivers need to be applied, for example, an outdoor driver for street light, an indoor point driver for a downlight, and an indoor linear driver for a panel light.Thanks for your time and join me on the channel
New Location, Cause for Hemp & Co.
The space is newer and greener and Hemp & Company has decided to use its new Government Street digs as a launch pad for a new environmental award.The 15-year-old Victoria retailer, which works to expand awareness of organic and eco-friendly clothing, nutrition and bodycare, has launched the Eco-Hero contest in order to shine a light on entrepreneurs, volunteers and community leaders who make a positive mark on the environmental landscape."We wanted to recognize people who are involved in environmental issues and we thought what would be a good way to support them and get the community thinking," said Bill Finley, who runs Hemp & Company with wife Lorna Knowles. The company will be taking nominations until Nov. 23 for individuals and then the community will be able to vote for their favourite between Dec. 1 and Jan. 31. The winner will be announced Feb. 5 and will win an "awardrobe" of Hemp & Company gear."There are not many initiatives likes this, that award eco-heroes," said Jill Doucette, founder of Synergy Enterprises, a firm that works with companies to improve their green practices and worked with Hemp & Company to develop the award idea.Doucette said the contest will mean environmental leaders are profiled in the community and lauded for what they do, whether it be land conservation, developing innovative technology or rallying the community behind a cause."Hemp & Company loved the idea of connecting with environmentalists that share their vision," she said.Finley said that environmental bent is a huge driver behind the store, now open at 1312 Government St., two blocks from the old location at the corner of Government and Fort streets."I'm an environmentalist more than anything else. I've been on the protests and hugged the trees and all that and it's all well and good, but I always felt a little unsettled as it wasn't proactive," he said. "This business came along through my son [Mike Finley] and it felt like a business where you could do something and hopefully make a difference in the world." The new store makes a difference as well. It is smaller than the last locations. It has 1,300 square feet of retail space and includes a number of features that "green" the place up.The work and lease-hold improvements on the space within the newly renovated New England Hotel, an 1865 building, led to the company recording the highest score for a retail business on the Island from the Vancouver Island Green Business Certification program."When I completed the assessment at Hemp & Company, I was truly impressed," said VIGBC program manager Craig Sorochan. "They have integrated sustainability into everything from their light fixtures and flooring to the products on their shelves." Finley said most of the initiatives had been done in the old store as well - a heavy-duty recycling program, no plastic bags and the like. But the new store also includes wood reclaimed from an old aircraft hangar in Comox used for flooring, recycled lighting fixtures, LED lighting and a heat pump for heating and air conditioning."We thought of all the things we could and did whatever we could within the fine budget we had to create a space that was as green as the products we are selling," he said.Doucette said the company has been a "long-standing pioneer of environmental initiatives and products. They have always been on that cutting edge of the next environmental solutions and very supportive of local business."
How to Fix Dc 12 Led Lights That Burn Out Due to Excess Voltage Or Current
Unfortunately you do not tell us how much current is needed by your LEDs and fans.Assuming that this current is less than 2 A you could consider using a buck-boost converter like this:In the description this model is listed as usable up to 3 A but you have to take that with a grain of salt. I would use it up to 1 A and not be worried. Maybe it would survive 2 A just fine, At 3 A it might get too hot and not work in the long run. Then it would be better to use a module rated for 5 A.Actually the name is wrong as the converter first boosts the voltage up to for example 24 V and then uses a DCDC down converter (a buck converter) to lower the voltage to the voltage you need, for example 12 V.This means the module will output 12 V as long as the input voltage stays within (quite broad) limits. So even at 10. 5 V or 15 V at the input, you will always get 12 V at the output.There are many different modules similar to this one, just search for "Buck boost module"1. What do I need to buy for my car to make LED lights flash to music?You need a modified color organ circuit, basically band pass filter, level detector, and comparator2. If i buy a custom xbox 360 controller can i change the led lights from the default green to purple?You can. You have to either put them in yourself, or get them like that. As for the battery drainage, if you are just getting it in the circle around the "X" then no. If it does, it will drain it so slightly, you wo not even notice a difference. Just make sure you use eco ones.3. In New York state, is is legal for a motorcycle to have LED lights on while moving?As long as they are not blue or red you can get away with it.4. My Frigidaire GLTF2940FS1 is plugged in but will not start nor will the LED lights come on?check the circuit braker box and make sure it's on. if that's ok, then test the outlet itself with a small appliance5. How do you solve the "half strand out" problem in a strand of LED lights?One of the bulbs in the light strand is defective could be more than one bulb. Find the defective bulbs in the strands and you will have a full working 100 light strand. I've been doing this for the past two weeks hanging my christmas decorations. That was the problem in every strand that did this to me.6. Is it against the law to have blue LED lights on your car in Pennsylvania?Who cares? They are ugly anyways....7. Can I use a 125v toggle switch to hook up led lights to a 12v battery on a motorcycle?12 Volt Toggle Switch8. What's the real Pros of using LED lights?they last waaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaay more than normal bulbs9.

The results as published by them? "No battery lasts longer than ours!" Ooooh, boy. I think you better just go with the best buy, that's what I do. Welcome to the wonderful world of advertising.
Are Fluorescent & LED Lights Making You Tired?
Did you know: some of the lights you have in your house are damaging your mitochondria (and thus adding to your fatigue)?Your mitochondria are so attuned with your environment that even the types of light you are exposed to each day can cause fatigue! The "bad" light I'm referring to here is a modern-day invention. Some refer to it as junk light. Others as white or blue light.The mitochondrial damaging light is a recent development for the human species. I'm referring specifically to compact fluorescent bulbs and the new LED (light emitting diode) bulbs - yes those same ones that last for years and years. These bulbs contain specific wavelengths of light that are particularly damaging to your mitochondria.And as I hope you know, underfunctioning and/or damaged mitochondria results in fatigue.Your body on lightYour ancestors had been exposed to the same type of light (the sun) for millions of years. (1) Millions of years! That is an incredibly long time for your body to adapt to one type of light. Through the sun, your mitochondria are best able to absorb and utilize light. They struggle when exposed to modern-day lighting.The compact fluorescent light was invented in 1976 and made its way into houses and offices in the 1980s. (2) Compact fluorescent bulbs are the spiral bulbs like the one found in the picture at the top of this post. The fluorescent tube lights - the ones you commonly see in office spaces - began being sold in 1938. Making their way into most offices by the 1950s. (3)LEDs (light emitting diodes) are the most recent lights to enter the commercial market. They were developed in the 1990s and only became affordable in the past few years. (4) LEDs are adored for their long lifespan - lasting ten times longer than incandescent bulbs. More recently, it's these bulbs that come enabled with wifi; allowing you to adjust the brightness with your phone.For millions of years, your ancestors were only exposed to the wavelengths of light put forth by the sun. In the early 1900s, the incandescent light bulb changed that. Humans were able to illuminate the dark. Fortunately, the wavelengths found in the incandescent light bulb were not too far off from that of the sun.It is the compact fluorescent (CFL) and LED bulbs that affect your mitochondria in a very bad way. These lights lack the wavelengths/frequencies found in natural sunlight. The infrared, red, and violet wavelengths found in sunlight are completely eliminated from LEDs and CFLs. And the blue light frequency has been amplified.Take a look at an old-fashioned incandescent light bulb. Notice how the light emitted has a warm orange/red/yellow color to it. These are the red, infrared, and violet wavelengths being expressed. Now, look at an LED or CFL. Notice how that light looks blue and white, and it's almost irritatingly bright - this is the blue wavelength predominantly expressed.Your genes have been exposed to sunlight for millions of years. And to blue light for less than thirty years. Your genes have not adapted to this modern, artificial light. And because of it, your mitochondria are suffering. This is how something seemingly as benign as the lights in your house could actually be adding to your fatigue.Shedding some light on your mitochondriaYour mitochondria are your body's power plants. These tiny structures, found within nearly every cell in your body, produce a substance called ATP (adenosine triphosphate). And ATP is the energy that powers your body.Those with chronic fatigue syndrome and/or myalgic encephalomyelitis have a reduced functioning of their mitochondria. This results in a net energy deficit. (5) In order to increase your energy and overcome fatigue, you need to optimize your mitochondrial function.And the lighting you use in your environment is the perfect place to start.Just like you, your mitochondria have evolved over millions of years to utilize the energy of the sun. They have not adapted to utilizing the blue wavelengths found in modern daylight sources.One study showed that after only six hours of exposure to blue light, mitochondria were not able to produce energy as efficiently. As exposure time increased beyond six hours, mitochondrial function continued to decline. (6) It is hypothesized that exposure to blue light increases cellular aging and age-related illness. This occurs because blue light is thought to damage the DNA of your mitochondria.Suffice it to say that if you're dealing with fatigue, you need to minimize your exposure to blue light. But what do you use for lighting then?How to avoid blue lightIf you have chronic fatigue syndrome, the very first thing you need to do is ensure your home (and hopefully your office) are free from LEDs and CFLs. Replace these bulbs with incandescents. The small amount of money you save on your energy bill using CFLs or LEDs is not worth the cost to your mitochondria.If you work in an office where you don't have control of the lighting, you're going to need to be extra vigilant. To combat blue light exposure, you need to increase your exposure to red light sources. Your best bet will be getting outside every chance you get.Take your coffee break outdoors. Go for a walk at lunch. Look out a well-lit window. Try to get outside when the sun is at its zenith in the midday. Stay outside for at least fifteen minutes, ensuring you have as much skin exposed to the sun as comfortable.What do you do if you live at a latitude that results in very cold temperatures for half the year? Or, if you live in an area constantly covered by clouds?You're going to need to utilize technology to increase your red light exposure. In the morning, expose your body to an ultraviolet sun lamp. I recommend spending 10-15 minutes each morning during the winter months in front of it. While working in your office, invest in some red LEDs. These will ensure your mitochondria get exposed to the red wavelength during the day. This simple act will improve your mitochondrial function and in turn increase your energy levels.While the type of light is indeed very important, the time in which your body gets exposed to light is equally important.AM light and PM lightDo you hit the snooze button 10 times each morning?This morning fatigue is often caused by a suppression in your cortisol awakening response (CAR). The cortisol awakening response is a surge in your cortisol levels shortly after waking. It is this surge in cortisol that should energize you to get out of bed in the morning.In order to trigger a healthy CAR, you need to get exposed to sunlight immediately after waking. If you live at a latitude that results in a sunrise well after your alarm, you need to invest in a full spectrum UV light. Turn your UV light on immediately after your alarm goes off. This will mimic a sunrise ensuring your body has a healthy cortisol awakening response. This is why so many people notice an increase in fatigue during the winter months - a lack of sunlight exposure.As the day progresses into night, you're going to want to decrease your body's exposure to blue light. Blue light is the wavelength that signals to your body that it's daytime. It's this wavelength that suppresses melatonin production. Remember, you need your body to produce melatonin in order to easily fall asleep.In the evening, ensure your electronic devices (cell phone, computer, television, etc.) have their blue light filter enabled. This blocks the blue light frequency from screens which ensures your body is still able to produce melatonin before bed. There are apps like f.lux that you can install on your devices to ensure blue light is blocked when the sun starts to set. Most cell phones come equipped with blue-light blockers in their operating system.Devices aside, as you approach bedtime, you are going to want to decrease your body's exposure to all light sources. Your skin is the largest organ in your body. And it is full of light receptors. Even if your eyes are not exposed to light, your skin will be. Dim all your lights two hours before bed. And be absolutely certain that your body is not being exposed to any sources of blue light.Make your bedroom as dark as a cave. It should be so dark that you struggle to see your hand in front of your face. Blackout blinds are a must (especially in the summer months). Ensuring your bedroom is this dark will allow your body to produce enough melatonin to keep you asleep all night long. Restful sleep is absolutely essential for anyone working towards overcoming fatigue.One last trick that can improve your sleep is to purchase (and use) orange-lensed glasses in the evening. These glasses block the blue wavelength from entering your eyes. Doing this will help increase your body's melatonin production. Resulting in a more restful sleep.Ok, now you know just how important the right type of light exposure is in overcoming fatigue. Do not underestimate the importance of this. It is so important that I include it in my eBook - seven small steps you can take to overcome fatigue today.Now it's time for me to hear from you!How has changing your lighting changed your fatigue?Want to know more than your doctor about how to overcome fatigue and increase your body's energy reserves?

Gateway Desktop LED Lights Up, but Computer Doesn't Turn On?
the same thing happened to my gateway too! i took it back to best buy and they said it had something to do with the motherboard...but since i bought it still in warranty they replaced it with another crappy gateway since it seems to have a motherboard issue as well1. How to power LED lights without using an outlet?Yes, you can use a battery. Details would depend on the number of LEDs, their specifications, and how long you expect the battery to last. repeat, need more details. There are many ways to hook them up depending on the battery size, and LED specs. In general, you need a resistor of the right value, in series with each LED or set of LEDs in series to set the current. .2. Is a bridge rectifier needed to power LED lights from a DC Power Source such as a cordless tool battery?Basic circuit for powering a single LED from a batterysimulate this circuit - Schematic created using CircuitLabBUT, 'LED light' might mean any complex arrangement of multiple LED elements power supplies current limiters and so on3. What's the law for red led lights? I got red ones and it says they go under my hood above my headlights?You are not permitted to display red lights to the front. Unless it is on a registered emergency vehicle4. I want to buy a used lexus but with led lights, what year?If you mean HID headlights. I would recommend an IS300 (2001-2005) They are really affordable and the of the highest quality for your buck. Lexus/Toyota is rock solid reliability and I know of so many that have painlessly exceeding 300,000 miles and still running like new. The is300 is a compact 4 door sedan with luxury and performance suitable for most needs. The parts are relatively cheap and aftermarket options are endless. Size of vehicle relative to BMW IS = 3 series GS = 5 series LS = 7 series I like smaller, personal compact sedans but if you are going to be carrying other passengers really often I would suggest a GS300.5. Will leaving the 12V socket into the cigarette lighter socket drain battery? even if led lights are off?If the automobile is off, and the light on the charger cable is off, it surely does now not drain the battery at all. There are some cars where the accessory plug is are living even with the vehicle off, but if the sunshine is going off while you turn off the vehicle, it's not on, and if it is not on, it cannot drain the battery by any means6. Why do those small LED lights break so easy and what can you do to fix them?The base of the LED lights contains an electronic circuit to convert the AC voltage to the proper DC voltage to run the LED lamps. These circuits are called an "electronic ballast." These bulbs were not designed to be shock-proof, so there is probably a broken circuit connection in the base, or in the wires leading up to the LED lamp, itself. It is not cost-effective to try and repair them, but they *are* probably repairable by someone who knows how. (I would personally try to fix one of mine, if they were to break.) .7. Is it possible to change the color of the led lights that backlight the keys on the razer lycosa keyboard?You probably could, but would not be worth the trouble. The colour cannot be changed without replacing them. What colour did you want? =) The term "non-adjustable LED's" I think refers to the colour and brightness not being adjustable. Keyboards these days have SMD LED's (surface-mount) that are tiny, and require you to posess surface-mount soldering experience! I do not think even an electronics engineer would want to waste his time replacing all the LED's. Sorry.8. Where can I find individual LED lights?This Site Might Help You. RE: Where can I find individual LED lights? I can not find just Individual led lights.

Are 5000k LED lights bad for your eyes?Led not good in general for the eyes3. is it bad to keep the LED lights that are under my fish tank on for long periods of time ?I am not sure if it's bad or not, but I know it promotes algae growth, and I also know that fish PREFER darkness when they sleep. I actually did an experiment on it, where I left the lights on in a room and I had two tanks connected to eachother, and one was completely blacked out with paper, no light came in, and one was completely lit with a lamp and everything. During the day, they would chill in the lighted side, and every night, NO FAIL, they would swim to the blacked out side of the tank. Crazy, but true.4. What fuse controls led lights around the linkage gear lever?Remove the gear cover, locate the light. Light is out, change it5. No boot, no beep codes. MB LED lights up and fans come on.?!!! you dont have to have a video card to get a beep post. Check the seating of the ram sticks if not then you either have a bad motherboard or processor. You have to switch either of them to figure out which one it is. Hell it could be both. Just take out the processor and put it back in(try to see if there is a burn smell while you taken it out) and reboot if nothing then you probably have a bad motherboard. See if you can put your processor in another motherboard to see if the processor has gone bad6. help can i do this to my led lights?Hi, Yes you can, you could add another fuse and cable to that existing line using a suitable crimp connector. I might also add that you have put your question in the computer section... not really the place for this question.8-(( Arnak7. What is the electricity situation in Zambia? Do people use LED Lights? cellphones instd of wired phones?About 19 percent of households in the country had access to electricity. More households in urban areas, 49.3 percent had access to electricity than those households in rural areas, 3.2 percent. Among the provinces, Lusaka recorded the largest proportion of households with access to electricity (51.4 percent), followed by Copperbelt (43.9 percent), Southern (13.5 percent), and Central (11.9 percent). The province with the lowest proportion of households with access to electricity was Western Province (3.5 percent) A modern house in rural Zambia has no electricity. Instead it uses paraffin and candles for lights, a car battery to power a record player and small batteries to run a radio/cassette player. It is perfectly possible to manage without electricity. As Zambia is a country with plenty of sunshine, solar panels can be used to generate electricity. So, I cannot see them wanting to be bothered with a huge bicycle and waste energy by pedalling when the sun can do the work with a small gadget.8. Why don't my led lights work correctly on my motorcycle?You need a load equalizer. There is very little resistance in LED's. providing everything else is hooked up correctly9.
