LED低光衰驱动电路设计

The Driver Circuit Design of LED Low Light Fade

大功率LED灯的散热仍然是LED照明行业发展的瓶颈。若散热问题得不到解决,将会使LED灯的温度上升,导致其发光亮度减弱、使用寿命缩短。因此加强对LED的过温监测与过温保护电路设计是十分必要的。

The high power LED lamp cooling is still the bottleneck of the development of LED lighting industry. If the heat dissipation problems can＇t be resolved, it will cause I.ED lamp temperature rise, leading to weaken the illumination brightness, shorten service life. Therefore strengthen the over-temperature monitoring and the over-temperature protection circuit design of LED is necessary.
