How to use LED tube lighting

     The power supply of LED tube lighting has two kinds of built-in and external. The biggest advantage of using the built-in power LED tube is able to directly replace traditional fluorescent lamps, without the need to remove any components. For best performance, we recommend using a centralized external power LED tube. At present, the main place of using LED tube is the government agency, office, shopping malls, schools, underground parking, subway and so on. These places are often using multiple lights in a room, you should adopt a centralized external power supply. It is an isolated power supply, no high voltage at the lamp tube, only DC low voltage less than 36V, which is conform the conditions of safe use.
     The only drawback of LED tube lighting is the higher prices. But its long life, energy, pollution, etc., from the point of view of these advantages is still very cost-effective. Especially in need 24 hours of continuous lighting the place, after it was used for some time, energy-saving effect is obvious.
     In the use of LED tube lamp should pay attention to the following issues:
1, to pay attention to the rated voltage, high voltage will damage the LED.
2, the installation should cut off the power.
3, LED tube suitable for indoor lighting, the working temperature is -20~50 degrees, should not be installed in the easy to rain or moisture place.

How to improve the luminous efficiency of LED downlight

     A good LED downlight, not only the appearance of fashion and elegant, and have higher luminous efficacy. The luminous efficiency of LED downlight be related to its overall design. How to improve the transmittance of LED downlight? Under normal circumstances, the light efficacy of LED downlight is good or bad, there are mainly two factors, the first is the quality of the light source, and the other one is the lampshade material, and the transmittance of lampshade.
     1, light source
     To improve light efficiency of LED downlight, the first thing to consider is the light source of LED downlight. The quality of the light source has a very important role, even if the lampshade is very good, if the light emitting efficiency of the light source is low, then the light efficiency of LED downlight is not very high, you can do a simple analysis, some high lumen light source in general can reach 80-90lm/w, this value is very common on the market, however, the only light source. The luminous efficiency of the light source has a certain relationship with the matching power supply, At the appropriate operating current, can give full play to the light efficiency of the light source.
     2, lampshade material
     On the condition of light efficiency of the light source is guaranteed, another factor affecting the luminous efficiency of LED downlight is shade material. There are PMMA, PC, glass. The difference between them: one is the different materials, on the other hand they have their own processing methods, after some special treatment will achieve higher transmittance. After processing, the light transmittance of glass is the highest. PC cover is a kind of commonly used material now, because of its relatively low cost, now a lot of LED down light or the other LED lighting is the use of PC material. The transmittance of PC cover above 80. The comprehensive calculation, the light efficiency of natural white of LED downlight in about 75lm/w, this is quite normal, the transmittance of glass cover is better, can reach more than 85. So the LED lamp manufacturers in order to improve the luminous efficiency of LED downlight, the light source and the light transmittance of the lampshade is the key objects.

How to repair LED ceiling light

     Because the LED light has the advantages of energy saving, environmental protection, long life, it has gradually penetrated into Home Furnishing lighting. Many people decorate the new house, will buy LED ceiling light, LED downlight, take them as the main lighting home, make Home Furnishing environment more fashionable.
     But in the process of using LED ceiling light, will inevitably encounter damaged or dead lights of the situation.  At present, LED ceiling light price is more expensive than the ordinary energy-saving lamps, if the replacement of the whole lamp, is not worthwhile, if can self repair is the best. Here, describes how to repair LED ceiling light for you.
     LED ceiling light does not light, the main reason is in two aspects, one is the problem  of the light source, another problem is the power. At present, LED ceiling light light source is made of SMD LED lamp beads, first turn the power off, open the shade, measured with a multimeter, to judging whether the LED light source is bad (beads are generally in series), if it is, then look at the light source style, and then buy a the same light source and replace it. At the time of purchase, should pay attention to voltage range of the light source, the light source voltage must be the same.
     If using a multimeter to detect light source is no problem, then look at whether the problem is the power, the general LED ceiling light are methods of external power supply. If the power supply is bad, buy a power supply and replacement. If the LED ceiling light manufacturer uses the power supply is not qualified, the power is very easily go wrong.

What is the LED tube

     With the LED lighting technology to improve, LED lighting occupy a lot of space in the market. LED tube is one of them. What is the LED tube? This paper have a simply introduce LED tube for you.
     Both ends of the traditional fluorescent lamp each have a filament, there are trace of argon and mercury vapor in the tube. On the inner wall of the tube is coated with fluorescent powder. When electrified the gas between the two filament produced ultraviolet, make phosphors emit visible light. Because it contains heavy metals pollutants "mercury", fluorescent tube scrapped environmental pollution is very serious. The LED Tube uses light-emitting diodes as a light source, higher efficiency, more energy efficient, longer life, and more environmentally friendly. At present, become the most ideal products to replace the fluorescent lamp. LED tube and traditional fluorescent lamp dimensions are the same on the caliber, have LED T5 tube, LED T8 tube, T10 tube, length of 0.6m, 0.9m, 1.2m, 1.5m, 1.8m, 2.4m.
     LED tube installation is very simple. When installed, remove the old fluorescent lamp, put on the LED tube, and remove the ballast and starter, can be directly to the LED tube connected to AC power.
     LED tube energy saving up to more than 70%, life is more than 10 times the ordinary lamp (theoretically can reach more than 50000 hours), require little maintenance, does not exist often replace the lamp tube, a ballast and a starter question. Semiconductor light source, green environmental protection type soft light, pure color, protect people's eyesight and physical health.

COB led downlight the development trend in the future

     The development speed of LED downlight beyond my imagination. The initial stage of LED downlight, its light source is mainly the LED light bead. After a period of time,  the emergence of SMD and COB. Some people think that COB belongs to downlight, but I think the COB is upgrade spotlight, and can slowly replace high-power lamp bead downlight.
     COB led downlight is upgraded version of the traditional downlight and (LED down light), lamps compact, suitable for different places, use a wider scope. Generally used for auxiliary lighting and decorative lighting. Can make up defects of the traditional downlight and LED downlight, is the future trend. Now the COB products still in the transitional stage. We believe that in the next few years, COB led downlight will be a large number of occupation of the market.
     At present, there are many LED lamp manufacturers in the production of LED down light, this shows that the demand of LED downlight in gradually increasing, so LED downlight market prospects are very considerable.
