According to the author to incomplete statistics , the failure of today's LED lighting products generated about 80% from the power supply , from years of continuous development of LED panel lighting products packaging technology continues to improve and cooling technology , the stability of the light source has reached a good level even that is said to have bad light and color drift , which is mainly caused by the irrational thermal design . Direct necrosis situation has very little power is relatively more serious problem to a problem generally occurs directly dead lights or flashes , and the relatively high frequency of occurrence . Materialist dialectics tells us to fix the principal contradiction , the main contradiction is resolved minor conflicts will be solved.
Conventional street lighting failure and the need to maintain a light sodium , sodium national standard warranty period of one year , street unit will keep a certain amount of sodium library . Sodium lamp with a mature national standards, its main parts size, power and other key parameters are uniform , with interchangeability. The current failure of the main power LED lamps , so to solve the main contradiction is to solve the power problem . Due to the current lack of a mandatory power LED uniform standards , fragmented market power , single-channel , multi-channel , different sizes , resulting in many problems. With the ultra- high-power LED market power appears , 4 or more drive power everywhere , so frequent failures , but also forced LED panel lights when the cost of the overall design , modeling of the storm , coincide on many factors, often resulting in LED power supply maintenance difficulties heavy , and thus the owners complained, the media fanning the flames caused by a misunderstanding of the LED tube lights we affect the industry 's reputation and development.
I advocate the development of LED lights drive power five-point concept :
1 to give up power, ultra- high-power , high stability of development of small and medium power supply , preferably between 30W-40W, the maximum should not exceed 50W. Because the greater the power , the greater the fat calories, which is also more compact components , is not conducive to the heat , and the temperature is the culprit of a power failure . Furthermore , the development of small power relatively more mature , stability and cost has advantages. In fact, many power companies do not know the greater the power , are reluctant to do high-power , but under the pressure applied manufacturers , to develop high- power passive , many programs do not have the time-tested and proved , are hastily implemented the projects are experimental products, so failure after another. In contrast medium power supply due to the early development of the technical solution to mature more. " Moso Power Supply Technology Co., Ltd. " The technology solutions designed to instill an interactive lighting manufacturers , power companies and product applications business , which greatly reduces the failure rate and improve the quality of lighting products , power companies , lighting companies , the owners have benefited , too.
