How to select LED lamp driver power correctly
Relatively speaking, LED lamp driver power problems are more serious, is the main reason leading to dead lights or flashing, but also the quality of LED lights short board.Conventional lighting lamps are separate lamp and power, usually failure is a lamp - high pressure sodium lamp, high pressure sodium lamp set the national standard warranty period of one year, street management unit will store a certain amount of sodium lamp, high pressure sodium lamps have mature national standards, the main parameters of the main parts size and power are unified and have the interchangeability.
Intelligent control is one of the advantages of LED lamps, and power supply is the key of intelligent controlIntelligent control in LED street and LED tunnel lighting application conditions of the most mature the most obvious effect, intelligent control can be controlled in different time, to realize the stepless lamp power according to the road traffic density, can meet the application requirements, and realize the enormous energy-saving effect, can save a lot of money for the public road authorities. The application of tunnel lighting can not only save energy, but also automatically adjust the brightness of tunnel entrance and exit according to the brightness outside the tunnel, and provide a visual over stage for drivers to ensure driving safety.
The current LED lamp fault is mainly in the power supply, so the main problem is to solve the power supply. As the current LED power supply is still a lack of mandatory unified standards, the power supply on the market fragmented, single, multi-channel, different sizes, it is difficult to replace. With the advent of the market of super power LED lights, LED tunnel lights, LED drive power failure frequently, coupled with the LED street lamp driver design of built-in power supply used, often resulting in LED lamp power supply maintenance difficulties, and some manufacturers lack of customer service repair services, so the owners of complaints are heard everywhere, by the media hype caused by misunderstanding the LED lamp, the effect of LED industry reputation.
