The continuous development of the LED lamp strip package technology and cooling technology in recent years, the stability of the LED lamp strip has reached a good level, the occurrence of light attenuation and color drift is mainly some copycat product manufacturers, the main reason is the unreasonable design of heat dissipation. Relatively speaking, LED lamp strip driving power supply problem is much more serious, it is the leading cause of death or flashing lamp main reason, that is to say, LED lamp driving power supply has become a short board of the LED lamp strip quality, according to the theory of barrel, life of LED lamp strip driving power supply is the life of the LED lamp strip.usually failure is a lamp – high pressure sodium,, high pressure sodium lamp, high pressure sodium lamp provisions of national standard warranty period of one year, the street lamp management unit will store a certain amount of sodium lamp, high pressure sodium lamp has mature national standards, the main parameters of its main parts size and power are unified and having interchangeability.current major fault of LED light bar in the power supply, so the main problem is to solve the power supply. But because of the standard is still a lack of LED power supply, power supply their own market, for example there are have a single road, the size is different, it is difficult to replace. With the advent of the market super power COB LED resource lights, LED tunnel lights, L LED drive power failure-prone, and the LED lamp with built-in driving design of power supply, often caused LED lamp power supply maintenance is difficulties, the lack of some manufacturers of after-sales maintenance services, so the owners complained, the influence of LED industry reputation.
