Bo said that according to the great cause of national standards, test methods and performance of traditional fluorescent energy saving lamp is tested 2000h and 6000h life light fades. LED lighting products currently CQC energy certification is a measure of 3000h, 6000h and 10000h to judge LED light failure lamp life; while the US Energy Star certification for LED lighting products, light attenuation test minimum requirement is 6000 hours. The actual life of these test methods can detect, although the sample, but the test time is too long, the test costs are too high, can not meet the needs of the market. Because unlike traditional lighting technology is relatively mature and stable, rapid development of LED technology, every six months, with a chip and product appearance products has changed a lot, until 6000 hours of light fades test done, the product may have been the market eliminated, so we have to find a faster and more reliable scientific detection methods LED lamps. If the LED lamps as a system, based on the reliability of detection, we can divide it into three subsystems, namely the light source module (module) subsystem, power supply subsystem and interface subsystem. I believe that some of the current research institutes to carry out the overall lighting life accelerated test and then to predict the life of this method is not appropriate. Failure principle and acceleration principle different systems are huge differences in Zhengzhou Spotlights production which company is good, get out of the data is not reliable. Therefore, it should be treated separately according to different subsystems. Bo-saving lamps cause prompt you really saving? First of all, we must be clear about the concept of energy saving, accurate to speak in Zhengzhou, where under the same definition (CRI light source equivalent) Spotlights premise produced the best, effective unit receive the same area of ??the power consumed by the illumination light source, the more the lower the energy. Of which there are several key points: first, the same clarity, sharpness depends largely on the color temperature of the light source, since the 5000K-6500K white light to maximize the reduction of the original color of objects, natural in the human visual clarity on higher. Why the emphasis on effective area, which is designed to light a problem, because a lot of light is 360 degrees or 180 degrees luminous light, and the angle of lighting we need may be 120 degrees or 90 degrees. Third, the same illuminance consumed less power, because the power company is based power tariff collection, of course, less power consumption and therefore fewer Zhengzhou largest Spotlights manufacturer should be noted that the consumption of power with power factor is not directly related to the power factor does not affect the level of power, but the issue relates to line loss. Now we use these standards to weigh the energy-saving lamps cast light, first look at the color rendering index, CRI universal saving about 70, pure three-color phosphor should be able to do about 75, should be in terms of the color index is good; look luminous efficiency, luminous efficiency energy-saving lamps popular in 45-50LM / W, pure three-color phosphor should be done 50-55LM / W; finally see utilization, due to the energy-saving lamp is a surface light source, light-emitting area is large, light itself is more difficult, besides saving lamps either spiral or U-tube light issued basically horizontal direction, and all we need light generally vertical direction, and therefore requires a very a large mirror to change the direction of the light cover to make it down the photos.
