The Benefits of Upgrading to LED Lighting

There are certain areas within industrial facilities that don't get the attention that they deserve. An example of this is lighting. Nobody pays attention to lighting because while it is working, nobody needs to do much to keep it going.Looking at the numbers, lighting in any facility uses a lot of energy.

On average, lighting in industrial plants within the US uses about 10% of the power consumption. Reducing this amount of use becomes a logical step to save money.LED LightingSwitching to LED lighting is something that saves money.

The ROI occurs soon after the upgrade takes place. After all, LED lighting uses as much as 80% less energy than a standard incandescent bulb. Soon after installing LEDs, your utility bills drop very fast.

As energy rates continue their climb, the energy-saving benefits of LED lighting become more and more apparent.LED QualityComparing the LED lighting to other methods becomes a concern for facility managers. LED lighting becomes a positive gain on your ROI; they cost less to operate and provide the same quality of lighting.

The benefits of LED lighting outweigh those of incandescent or fluorescent lighting.LED LifeThere are ways other than energy-efficiency that LED lighting benefits you. Regarding operation life, LEDs last up to 200,000 hours or more.

Incandescent light bulbs last up to 1,000 hours, while fluorescent bulbs last up to 30,000 hours. There is a direct relationship between the quality of lighting and the hours of operation of the two older bulbs. The older they get, the poorer the quality of lighting.

A related benefit to the long-lasting LED bulbs is the simple fact you don't have to buy bulbs as often.LED SafetySwitching to LED lighting creates a safer work environment. Since they provide a higher quality light, it leads to fewer workplace accidents that relate to lighting.

There is no way to measure the cost of accidents that don't happen. In other words, how do you declare a price for keeping your team safe? Reduced downtime and decreased insurance costs become an important factor for consideration.In SumLED lighting retrofit is a choice to consider in most industrial facilities.

It is one of the easiest of all methods for saving money on energy usage despite being ignored by facility managers for a variety of reasons. As electric rates continue to rise, switching to a high-efficiency lighting source is going to benefit your bottom line more and more

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
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."
LED Lighting Is the Prime Choice of Interior Decorators
The growth of technology and necessity of better light sources gave us LED lights. The sources have evolved from the traditional incandescent or fluorescent lights to LED. Compared to incandescent lights, LED lights have the lighting consume 60% less energy and provide similar brightness. The architects and interiors designers are now having much better options with LED under interior lighting. They can now experiment a lot of new looks because the LED flexible strip can be operated on ultra narrow platforms. The LED strip lights can be installed anywhere without much of a trouble and produces warm or pure white light. They are extremely low profile and highly flexible to be bent in any degree. The LED lighting can be installed in many ways with the help of fixtures and give a much better glowing effect in the surroundings.The LED lights are widely used to enhance the look of the home or office. It is luxury form of LED interior lighting because they give a whole new outlook to the space where it is installed. The contractors and architects today use variations in the lighting to give attractive look. It is available in vivid colors; hence they can be used to suit the mood better according to the environment and color theme of the surroundings. They also give the facility to be modulated; hence the brightness can be controlled. This complements the area which is illuminated and hence has gone a step ahead as compared to xenon or incandescent lighting. The interior decorators always use new & better options to decorate the home, office or hotels. Be it a book shelf, garden patio, kitchen cabinets or ceilings, LED has become their prime choice because of brilliant color combination, less heat generation and low consumption. The LED flexible strip lighting can be accommodated anywhere without much of an effort.The LED interior lighting has become the first choice for many to highlight other sophisticated furniture. The dug in LED under cabinet lights are placed directly into the cabinet or shelf making them non noticeable. The LEDs are primarily installed in living room area for maintaining more artistic interiors. The LED lights can be installed in process hence the area should be chosen extremely wisely during installation. LED lights are also available in flexible strip and aluminium tube format that can be used in interiors for highlighting purposes. These LED aluminium tube lights operate on a remarkably less power. The LED tube lighting offers a variety of colors and can have their brightness modulated with dimmer as required. LED lighting can be used in extremely narrow spaces and still give the required luminance. The lights come as a bar or disk and can be chosen according to the requirement and the space available. The decorators also utilize the accent lighting to enhance the look and highlight the counter tops with LED lights.

Light Quality Is Critical to Strengthen Adoption of LED Lighting-Made-in-China.com
To provide a more balanced portfolio of ENERGY STAR lamp products on the market and mitigate color quality as a barrier to wider adoption of energy efficient lighting products, Soraa proposed to the EPA a second high CRI tier with differential efficacy requirements taking into account the inherent lumen per watt trade-off as a function of CRI for phosphor converted white LEDs. Soraa proposed to keep the existing minimum efficacy requirements, but raise the color quality to a minimum CRI 90. For lamps with CRI between 80 and 90, Soraa proposes to increase the luminous efficacy requirements.Poll: Last time you cried ?I am crying as I type thisHave you ever cried because of a song?weirdly yes haha Hurt- Christina Aguilara the music video made me cry hysterically >What movies have you cried during?I am a guy and straight so yah my tears do not fall as easily.

RDECOM Soldier Center's Bright Idea for Lighting System Improves Illumination, Saves Energy
NATICK, Mass. -- The Research, Development and Engineering Command Soldier Center's Expeditionary Maneuver Support Directorate, or EMSD, has developed a new lighting technology that provides better illumination while using less energy than fluorescent tube lighting. Under a Cooperative Research and Development Agreement with Southern Cross Printed Electronics, Australia, and its U.S. representative BAM International, EMSD developed the Flexible Light Emitting Diode, or LED, Lighting System, which is also called MFLEX. The MFLEX system is part of EMSD's ongoing commitment to improving energy efficiency and reducing the logistical footprint of expeditionary base camps. "Although there are several alternative LED lighting solutions available to the warfighter, all of which provide the benefit of saving energy, which ultimately translates into fewer or smaller supply convoys, the major benefits of these lights are reflected in three measures: 1) the amount of time necessary to setup and takedown a tent, 2) the transportation weight and volume, and 3) the quality of the lighting," said Melvin Jee, leader of the Soldier Center's EMSD's Expeditionary Command Platforms Branch. The Flexible LED Lighting System will replace the fluorescent tube lighting commonly used in the field. The system can be used in virtually any size tent, provides more illumination, and greatly reduces shadow area when compared to fluorescent tube lighting. "The flexible LED lights provide fairly even illumination, virtually eliminating heavy shadow areas, making the environment more comfortable for the warfighter by reducing fatigue due to eye strain," said Jee. By improving illumination and reducing the presence of shadows inside the tent, the system helps facilitate command and control functions. Soldiers often carry out various aspects of mission planning while in tents, including looking at maps and other information, and the improved illumination and reduction of shadows may help them better perform such tasks. Moreover, the system is more compact and weighs significantly less than fluorescent tube lighting. The Flexible LED Lighting System fits into a backpack-sized bag. This one small bag replaces up to four transit cases needed to light a single tent with fluorescent lighting. The cases weigh between 40 to 50 pounds each, compared with the backpack-sized bag needed for LED lighting, which weighs only 10 pounds. The backpack-size bag contains 12 meters of flexible LED lighting, complete with cables and hangers. The bag also contains the power supply and control circuitry, which allows the lights to be dimmed and/or switched from white light to blue/green blackout light. Warfighters do not require a specific Military Occupational Specialty, or MOS, to install and operate the lighting system. The LED system does not have to be taken down when moving to a new location, increasing ease of mobility and reducing setup and tear-down times. The system is being used by the 82nd Airborne Division. The Soldier Center has partnered extensively with the 82nd Airborne to gain insights into improving and developing appropriate tools, techniques, products and technologies for the warfighter. The division's feedback/input helped to shape the development of the Flexible Light Emitting Diode Lighting System. The U.S. Army Soldier Center is part of the U.S. Army Research, Development and Engineering Command, which has the mission to provide innovative research, development and engineering to produce capabilities that provide decisive overmatch to the Army against the complexities of the current and future operating environments in support of the joint warfighter and the nation. RDECOM is a major subordinate command of the U.S. Army Materiel Command.1. Cost vs Power: Checking out Some LED Lighting SolutionsEver wondered about the size of a salt grain? A single salt grain measures about three mil, which is a thousandth of an inch. Now, imagine a third of that size, placed on a printed circuit board (PCB). That is the size of the smallest LED available today. People do not regularly go for it, but it is heartening to know that something that small can also brighten something up. That is where the surface-mount device light-emitting diode (SMD LED) module comes into the picture. Now, you have a 0.65mm0.35mm0.2mm-size LED on a PCB that can be used for a range of different purposes. Wide viewing angles of about 145 and low power consumption add to the charm. An SMD chip is created from layers of man-made nano-sapphire and gallium crystal substrates. After growing these crystals, these are sliced, layered and bonded to a ceramic base. The chip can be then mounted in the required application. Applications of an SMD include everything from light bulbs to strip lights. One interesting use case would be the indicators on mobile phones. Over the years, SMD LED has continued to improve its luminescence in accordance with Haitz law. If a chip includes red, green and blue diodes, you have the possibility of creating any colour you want. This has resulted in SMDs becoming the prime choice for DC power applications, mostly due to the ease of use. A COB LED has great advantages of thermal resistance, larger cooling area, better lighting effect and high light efficacy. It is basically an LED built directly on the circuit board. P. Chow Reddy, managing director, Interleaved Technologies, explains, "A COB contains multiple chips within one large wafer. This allows a larger light output and a more even spread of light." It allows connection of the bare chip to the substrate by conductive or non-conductive adhesive and wire bonding to achieve its electrical connection. Due to fewer components in the LED chip, thermal conductivity is directed at the circuit board and without the traditional LED chip packaging structure. Heat emissions from LED chips are on average 25 per cent lower as compared to conventional LEDs, resulting in high efficiency and lower failure rates. And since the chip is built directly onto the circuit board, it reduces the need for spot soldering. After all, fewer soldering points mean less chances of failure. Need for traditional LED packaging parts and PC lenses has also reduced, resulting in an increase in light visibility range and a decrease in light loss from lenses. COB LEDs are generally larger than SMDs and range from a few millimetres to a few centimetres-square. At this small size, soldering these to the board becomes a problem. COBs are easier to place on a board. The pins in SMD require precision soldering An evolution over the conventional COB is the multi-chip-on-board (MCOB), for when one is not enough. It consists of multiple chips integrated into one larger single board. Assembly is cheaper compared to multiple single chips, making these suitable for applications in streetlights and high-bay lights. However, there is still some time before these can be used in smaller applications. Sharp Devices, Europe, recently announced a range of high-performance mini and mega zenigata COB LEDs with greater efficiency and enhanced hot lumen performance. HD6 mini zenigata are 12mm15mm with an 8mm light-emitting surface with 2500 lumens. BF6 series mega zenigata are sized at 20mm24mm substrate with 15mm light-emitting surface. Recently released are another two new blue LED chips from Light Avenue in 12V and 24V. Both solutions are sized at 140 mil to increase implementation in tracklights or high-bay lighting. Small-sized chips are clustered and packaged into a light bulb that is advertised as 'lighting always' or 'save power now.' Some LED manufacturers are able to reach 249 lumens per watt with a 20mA supply. However, this is not the story with bigger sizes. Light efficiency follows an inverse relation with chip size. Additionally, with an increase in current to the LED, efficiency is further reduced. One of the best things with the use of SMD and COB LEDs is that now you can get a much better looking LED display without having to pay as much for it-this brings in the matter of dual-in-line package (DIP) LEDs going out of fashion. DIPs have been around for more than 50 years, and are likely what you think of when you picture an LED. Though easy to use, these are much less efficient over other available options, and hence the reduced usage.2. Controlling light colour with DALIWhen planning lighting control with DALI, the focus nowadays is often on the pure function. Within HCL (Human Centric Lighting) there is frequently a demand for control of the colour temperature of accent lighting with saturated light colours. During the planning phase the user should always bear simple maintenance of the lighting installation in mind. It saves time and money if you can make adjustments yourself. But to do this you need expert knowledge. DALI is the standardized lighting interface in IEC 62386. Compatible devices are low in price, robust and easily available. There are stand-alone DALI lighting controls and numerous Gateway solutions in nearly all relevant building automation systems. For this reason DALI is aways a point of discussion in nearly every planning project for large functional buildings. However, even in the residential sector DALI is being used more and more, since, precisely when it comes to LED lighting, the function is guaranteed by being integrated directly in the DALI luminaires. There is no longer any need for complex compatible combinations of LED power supply, LED dimmer and LED module. The relevant functions are already integrated into the control gear. The strength of DALI becomes especially appparent with colour-variable luminaire combinations. DALI control gears are classified as standard in different types of device. LED control gears and luminaires are assigned to device type 6. Device type 8 is for colour-controllable luminaires. Colour control is standardized in DALI, which is especially important when colour control should span devices from different manufacturers to ensure that all the luminaires emit the correct light colour in the required intensity. It is possible to control in the brightness of luminaires in different ways using broadcast control or group and scene control. DALI operates according to the Master/Slave principle. The master can be a simple broadcast control device, such as the rotary control knob which can make a luminaire brighter or darker. The Master can however also represent complex lighting control. This might consist of many elements which communicate with each other in a superordinated network. If one DALI device fails, all project data previously saved, such as group membership, fading times or scene values have to be restored. In broadcast control all the luminaires which are physically connected to each other are triggered simultaneously with direct brightness values. In the DALI standard a broadcast address is set by default. All DALI luminaires obey commands which are broadcast-addressed, whatever address they themselves possess. Thus, it is not necessary to address and configure the luminaires. Faulty control gears can be replaced easily by new ones. In group and scene control the group allocation and the light scene values are stored in the control gear. The same is true for further parameters. Then the luminaires have to be addressed. When commissioning this is very complex because the luminaires must first be identified and then configured. As a rule, configuration of a DALI line is performed by the Master via PC software according to the principle of random address allocation. For DALI colour control with the conventional DT0 (fluorescent lamp) or DT6 (LED) a DALI address is required for each. The DALI luminaires have to addressed and grouped. The colour is defined via value control via several DALI addresses. When such a lighting solution is dimmed, the colour information is lost and commissioning is very time-consuming.3. How can I mount an 12V transformer for LED lighting inside a wall?You can not apply the low-voltage rules to transformers. Because half of the transformer is not low voltage, it is mains voltage. Anyway, you are talking about LED drivers or power supplies, not transformers. (a transformer is a real thing, it is a different thing.) Also, remember, the easy Class II rules for low voltage circuits do not apply if the circuit is over 55 watts
KMC Eyes Solar, LED Lighting for EM Bypass and Maa | Kolkata News - Times of India
Kolkata: The Kolkata Municipal Corporation (KMC) is taking a major step to turn green compliant. After the successful installation of solar lights at Deshapriya Park, the civic authorities are now working on plans to convert all street-lights into solar and LED on the EM Bypass stretch from Patuli to Ultadanga and on the Maa flyover stretch under the 'Green Cities' scheme which would help the civic authorities save Rs 4 crore electricity bill annually. Solar power expert and former managing director of West Bengal Green Energy Development Corporation S P Gon Chaudhuri has handed over the detail project report to MMiC (parks and gardens) Debashis Kumar at the KMC headquarters. "The proposal is to install solar power panels and LED panels on the entire stretch of EM Bypass and Maa flyover. It is a Rs 22-crore proposal in which 1.2 MW of solar power would be generated daily. The civic authorities would be able to save Rs 4 crore electricity bill per annum and this will also help reduce 12 tonne of CO2 emission per day," Gon Chaudhuri said. The other proposal that Gon Chaudhuri has handed over is to harvest 1.5 MW solar power from the Dhapa garbage field by setting up a solar plant. The solar panels here will be installed at a height of 10ft and vegetable cultivation could be done as well under the solar panels. This will ensure more moisture in the soil during summer. Kumar said the project will be taken under the state government's Green Cities Mission. "We had asked Gon Chaudhuri to prepare the report which we have received. It seems to be a very good project which will minimise our electricity cost and will also pave the way for a greener city," Kumar said. A total of Rs 40 crore will be spent under the scheme. After the installation of solar lights at Deshapriya Park, KMC authorities noticed a drastic 80% fall in electricity bill in the area.
Best Road Street Light, LED Light, LED Lighting,& Road Lighting
LED is one of the best lighting options for Road Street Lights. It produces bright and effective light.There are many companies who are using it in their business in a multitude of ways, from marketing to retail to energy saving applications. They are leading the way and taking the lead in this as well as other sectors where LED has shown its benefits.Street lights are crucial for safety as well as for visibility. Since the lighting process is an important part of the street lighting scheme, it is important to choose LED lights that will last longer and provide better light output.LED lighting is one of the most cost effective options for street lighting. However, it is not suitable for everything and needs a little customization. In this post we will show how to select the LED street lights based on your business needs and target audience.LED Road Street Light was a revolutionary invention that led to the development of LED lighting. It brought many benefits but also came with some disadvantages.For example, when it comes to outdoor lighting, there are still many places where LED lights are not permitted. For example, in some countries, it is prohibited to use LED lights on office buildings because of health and safety reasons.While the benefits of LED light could have made this product successful in the market, its disadvantages were also responsible for its downfall. When you compare it with other major brands such as Incandescent (generally considered as a good light source), CFL (considered as best choice for outdoor lighting), or PAR lamps (generally considered as the ideal indoor light source), then there is no doubt that LEDs are a better option than halLED road street lights are a big part of city traffic, and they're also very useful for different purposes. However, the lights have an annoying problem: some of them are dimmer than others. In order to find the best one, we need to get a lot of information about LED road street lights.Street lighting is mostly about the LED lights. However, there are many other options such as solar powered light bulbs and sodium vapor lamps.We have to look at the current generation of LED lights and their advantages/disadvantages. Some of them can be used in areas that require street lighting, while others are not suitable for street illumination such as urban areas with high pedestrian traffic or traffic-clogged roads. There are also some options that can only be used in countries with specific regulations, so it is difficult to use them outside those zones.LED lamp is getting popular through the recent years. This article will help you make a decision on which type of LED Road Lighting is best for the street lighting system.It was found that a lot of people are living in cities and they have to face the problem of poor street lighting every day. This might be due to issues like pollution, traffic, etc. This article will try to help you decide on which kind of LED Street Lighting system can be applied in your city or neighborhood and give you information about different types of LED Road Lamps available in market today.LED lights are cheap, clean and energy efficient.We are currently using traditional street lighting systems that generate electricity either from overhead power lines or from large generators. The connections to the grid are a lot of wires, many of which are fragile and can be damaged. Also the wiring is not as flexible as it should be to allow for dynamic adjustments in light intensity, angle and even colour due to wind conditions and weather. LED lights could solve these issues by allowing us to move lights around on rooftops without having to rewire existing infrastructure, they allow us to adjust the light bulbs at will also by moving them around the roof (perhaps with a remote control) which means we can change lighting intensity for our vehicles without having to stop traffic or make repairs on the road.LED street lights are a great energy saver but they can be very expensive. They consume a lot of electricity and in the end they don't last as long as traditional street lights. Hence, using LED street lights is not cost-effective.A bright LED bulb costs less than an incandescent bulb and yet the light produced by them is about half that of a conventional light bulb. And thanks to the cool white color, it can effectively illuminate up to 20,000 square feet without needing to turn on any additional lamps or fixtures.

As a matter of fact, now is exactly the time to start plotting (and potting.) what bulbs you want to plant. Some of the most beautiful plants that bloom each spring-daffodils, tulips, and Dahlias, for example-need to be planted in the fall in order to give them enough time to bloom in the spring. So how can you get the best results from your bulbs to have a stunning yard next year? The Maryland landscaping experts at Four Season are here to help. So you want to plant bulbs. Getting them to bloom so you can have a beautiful lawn is not difficult, you just have to follow the right steps and plan ahead. So how can you have a stunning lawn in time for next spring? Here are some tips to get you ready: • Timing is everything. Like anything in life, timing your bulb planting is essential. So when's the best time to plant your bulbs? You should start your plantings roughly six months out from spring. However, this is not an iron clad rule-there are mitigating factors to consider. • Check the temperature. When you are planting your bulbs, you need to make sure the soil temperature is cool enough. Bulbs are at their happiest when the soil temperature is between 40 and 50 degrees Fahrenheit. A good rule of thumb is to wait for the first frost, which in Maryland is usually between early October and early November. • Watch for sunlight. Bulbs like the sun-no shock there. So when you are planting them, plan in advance for the spring. Make sure your plants will get good sunlight. That mostly means avoiding the shadows of your house and other landscaping features. Since most trees wo not have leaves when your bulbs sprout, you wo not have to worry too much about tree cover being an issue. • Check for moisture. Plants like to stay dry. When planting your bulbs, make sure you have soil that drains well. If not, the bulbs could rot and not sprout. When planting your bulbs, make sure you dig a hole between 5 and 8 inches deep. Err on the lower side for small bulbs and vice versa for larger ones. The first year you plant bulbs, they wo not need any special fertilizer or plant food, but if you plant a perennial bulb, you will need cow manure to cover the top layer of soil after the flowers die for the season. You can pick this up at any gardening center, and it will keep your bulbs happy for years to come. Four Seasons' nursery has all the best plants for your Maryland garden.light bulbs?They are a little spendy but use the GE Crystal clear bulbs. Not only are you getting natural yellow light but since the bulbs are not frosted they give off more light. This means that where you used two 60 watt bulbs, you can now use two 40's and still light the room quite well. Saves energy and they just look cooler tooHalogen Bulb?A 20W halogen bulb is just over 100W in an incandescent bulb. I believe the 14W halogen is closer to the 100W incandescent . so it would be between 100-150W in an incandescent bulb.is a fluorescent bulb the same as uvb bulb?There are fluorescent "tubes" that produce UVA/B light but not ALL will. It will say on the box whether or not it produces UVA/B light. Also, there are huge arguments as to exactly what type of light produces the best UVA/B output. You can post another question about that if you likeDo tulip bulbs make more bulbs?i am not sure about the tulips but if you are looking for a flower that will mulitply then lillies are really good i planted one in 2007 then last year when they came back i had 11 stems come up and i was able to split them up and have 11 seperate lillies, if you do that you have to make sure that when you split them up that you take one of the bulbs with the stem try going on a website about tulips all you have to do is type in tulips and that will get you the info you need

What are the cons of LED lighting for growing hydroponics?how do you light your dro with an led? does it make the weed more powerful?2. Is it true that LED lighting makes one appear orange, as Donald Trump said?Do not think so, during my days at the dancing hall that had multi coloured lights never made anyone on the dance floor change colour. Maby Mr Trump has a colour skin problem, if he has it's not been passed down to his childrenAlex McInnes3. What kind of technology can we expect in the next 20 years?Advances in mobile electrical energy storage technology. A graduate student in California has found a method by which to greatly increase the useable life expectancy of a small rechargeable battery . . perhaps up to 200,000 recharge and discharge cycles. Present rechargeable batteries offer 300 to 1,000 recharge cycles before expiring. Extending the service life of even small batteries (flashlight, portable radio, portable CD player, camping lanterns, electric toys, e-bikes) would greatly change the way we live . . . more people could install solar PV panels on their roofs to recharge such batteries that could sustain home LED lighting. A breakthrough in polymer chemistry could construct a porous super molecule capable of holding massive amounts of static electricity . . solid state electrical storage with perhaps 1-million or more recharge cycles
