资料介绍

大功率LED灯有很多优点,而LED驱动电路对LED非常重要,LED驱动和调光是目前研究的热点。针对目前LED驱动电路的不足,设计了一种新颖的LED驱动电路,该电路以单端反激式开关电源为控制的第一级,压控制恒流源为第二级,可同时保证控制精度和效率。实验结果表明该电路效率高、功率大,同时电路还能自适应调光,更加节能可靠。

The high-power LED lamp have many advantages, LED driver circuit is very important to LED. LED driver and dimming is eurrent research focus. For current LED driver circuit deficiency, designed a novel LED driver circuit.The single-ended flyback switching power supply is the first level of the circuit, and the voltage controlled current source is the second level. It guarantee both the control accuracy and efficiency at the same time. The experimental results show that the circuit efficiency is high, large power, while the circuit is also adaptive dimming, more energy efficient and reliable.
