1. Modify led light controller for automated on and off?

measure the voltages on the wires and get back to us. .

2. Where can i buy fiber optic clips or led light clips?

I ordered 2 of these and put them in my hair for new years. I got tons of compliments and they looked great. There are several ways to wear them in your hair so experiment with what works best with your hair. I had them flipped up a bit so the strands were spread everywhere and it looked like I had little lights floating all around my head. If you just put the barrettes over your hair and do not do anything else they just make a neat streak of lights going down your hair. I also tried using a bobby pin to spread out the fibers to make more of a fan shape and it worked pretty well. Over all I really am happy with this product and will use them over and over again

3. The importance of lower light levels, shade, shadows and darkness in lighting

New lighting technologies are about to change the way we do lighting design, how we install lighting and how we will use it. Day is, of course, divided into daytime and night time or, put another way, light and dark. Daylight gives us energy and we can see to perform our tasks. Our bodies are structured and adapted to function in certain ways during periods of light and dark. We are inseparable from the universe and the sky above us but sky glow caused by city lights obliterates the night sky and makes it possible to see only a handful of the brightest stars at night. The reason is that we have lost all respect and perspective judging by the way we treat our planet and the amount of light pollution we create. I am just as guilty as most; I have designed street and sport field lighting over the years which contributed to light pollution before I became aware and more sensitive to the plight of the environment. So, I am not the accuser in this regard but rather the thought-provoker so that we can meet the future more sensitive to our surroundings. Indoor lighting is without doubt where we see most poor lighting designs. In my opinion, these are the result of the fact that no institution exists in southern Africa where illumination engineering is taught (other than the BHA School of Lighting in Cape Town). It has long been the practice to illuminate work places from corner to corner, with high uniformity and the same colour light as this was what the standards prescribed. On close analysis, the detail prescribed in the standards is only read where the illuminance levels are prescribed for each application type. The real important detail, including specifying the different areas within a single space which require different illuminance levels, contrast and glare are often overlooked completely. Often, the specified luminaires do not deliver the performance claimed by the supplier, which adds to the problem. Few lighting designs (if any) take into account natural daylight, to harvest it effectively or know and understand what daylight autonomy and continuous daylight autonomy mean, let alone how to incorporate them into their lighting design of interiors. Over-illumination is a cardinal sin in interior lighting and is the result of poor understandings or ignorance of the office layout or the tenant's requirements at the time of the lighting design. Perhaps it is also due to a lack of imagination and the inability to think about new and innovative ways to approach installations. Albert Einstein famously said, "Imagination is more important than knowledge for knowledge is limited to all we now know and understand while imagination embraces the entire world and all there ever will be to know and understand." He also said that approaching old problems from new angles "requires creative imagination and marks real advance in science." Lighting professionals, illumination engineers, consulting electrical engineers, architects and lighting designers owe it to their clients to know as much as possible about the subject of illumination, including all there is to know about light; the human eye; vision; lighting economics; physiology; physics; mathematics and, these days, lighting controls and the ICT environment. Office, commercial, industrial and other lighting will soon be powered over the Ethernet data system and will form part of the IT network. We must understand the requirements of each system so that software architects can design the software for use with the multi-faceted controls required by lighting installations. We can only concentrate on the business of lighting design once the requirements in terms of knowledge, understanding and experience have been met. Standards dictate specific illuminance levels on primary task areas. Areas adjacent to those areas can be around 60% of the task illumination. Pause areas in the building (where employees relax) can be 20% of the task illumination, but never less than 100 lux. Lighting in the pause area is not likely required for safety, making these areas ideal to treat as shade areas, restful places where lighting or the relative absence of lighting is provided for the workers' health and well-being. There are countless other possible uses for shade and even darkness to create visual effects. Workers prefer less light in these areas. The author has seen many offices and call centres where employees remove fluorescent tubes and cover fittings to reduce the amount of light. In most of these cases, management has either ignored the workers' preferences or paid "experts" for their opinion. These "experts" typically simply confirm that the lighting meets the standards or the OHS Act. However, luminaires can be repositioned and light levels reduced in these installations, with excellent post-intervention results. Few workers today do not use computers, often with their brightness levels set higher than needed to see the screen images because of the high illuminance levels in the office. While the standards require 500 lux where computer work is involved and a regular office requires only 300 lux, even 300 lux is too high to work in comfortably on a visual display screen. In Europe and in many new buildings with democratised lighting control (via smartphone apps), the average illuminance level preferred by the workers is between 150 and 200 lux. The scotopic and mesopic richness of LED light must also be borne in mind when using LED light sources or luminaires. Most light sources have a degree of scotopic/mesopic richness, most to a lesser extent than LED. Rogier van der Heide, former director of Arup Lighting and vice-president and chief design officer for Philips Lighting and the Zumtobel Group of Austria, has mastered the art of appreciating and incorporating darkness into his lighting designs. These include Amsterdam's Het Rijksmuseum (see Fig. 1); the Beijing Olympic Stadium; the Yas Marina Hotel in Dubai; Abu Dhabi's Sheik Zayed Bridge; the Canton Tower in Guangzhou; a Black Eyed Peas world tour; the Holland Casino in Rotterdam and the Swarovski Crystal Palace in Milan (see Fig. 2). Van der Heide quoted famous architect Le Corbusier in a presentation titled "Why light needs darkness": "Light creates ambience and the feel of a place as well as the expression of the structure". This sums it up: we should use light and darkness in our designs. The time has come for lighting designers to ensure that we not only provide light in a minimalistic way to meet budgetary constraints and the dictates of industry standards. It is time to use our expert knowledge to guide and influence clients and developers to budget for quality, healthy, modern and compliant lighting and the latest technology. Well-known American architect Richard Kelly (1910 - 1977) coined the phrases, "focal glow", "ambient luminescence" and "play of brilliants". His work included some very impressive lighting, such as the 1950s motor car showroom installation in Fig. 3. Kelly also reasoned that "darkness is needed for the imagination and for contemplation". There is much light pollution during sporting events due to the amount of light produced: around 39,09-million lm for 360 x1000 W LED floodlights, each requiring 1,6 A current compared to "old technology" which required about 11 A current per flood light. High-pressure sodium street lights are still predominantly used in Cape Town, although LED is making its appearance gradually. The amount of sky glow generated from Cobra Head luminaires is astounding. The International Dark Sky Association and the Model Lighting Ordinance (applicable overseas and hopefully soon in South Africa too) which require that streetlights produce no upward light at all and that the upward reflection off the road surface must be kept to low levels. Street lighting standards are important because the luminaires must be suitable for the different road categories, the different road surfaces, vehicle speeds, traffic density and location of the street lights such as urban or residential. Designers of street lighting projects have a huge responsibility to provide lighting to meet all criteria and to ensure that the correct correlated colour temperature (CCT) is used. Lighting designers should refrain from using high CCT luminaires at all costs. It is best to use 4000 K on highways and freeways where the speed limit is under 90 km/h. For all other roads, use 3000 K. We need to take note of the initial CCT debates and pay attention to the finding of the City of Montreal and the International Ophthalmic Conference who highlighted the unsuitability for motorists of any LED light with high blue light content. Human-centric lighting studies show that the lighting colour in the workplace should be toned down to a warm white around 3000 K towards the end of the workday. Exposing motorists to high CCT on their way home could delay the onset of sleep. It could, in fact, cause sleep disruption which can contribute to heart disease, diabetes and other ailments. Remember, you cannot simply substitute high-pressure sodium with LED of similar wattages. The result will be gross over-illumination and light pollution from reflectance off the road surface (see Fig. 4). Illumination engineers will understand that around 25 to 30% of the wattage for LED is required. Of course, luminaire design and performance will require careful analysis to be suitable for the different road types and categories. In the past, shop windows were interesting, different and appealing. They made each shop stand out and be distinctive. Today, it is simpler to light and control every shop window identically, possibly because so many of the shops in our cities and shopping malls are owned by major holdings groups. This is a shame as shops can increase sales opportunities by being distinctive. Exciting lighting allows the designer to use creativity, ingenuity and artistic flare with an understanding of light, shade, darkness and contrast (see Fig. 5).

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.
