摘要
调光功能是未来LED驱动器发展的一个方向,具有调光功能的LED驱动器不仅可以调节灯光效果,还能在一定程度上达到节能目的。应用白光LED驱动器芯片MP2481与光照度传感器芯片BH1710FVC设计出一款具有自调光功能的LED驱动器。该驱动器以AT89C2051为控制核心,接收光传感器数据处理后控制MP2481实现自调光功能。试验证明,驱动器实现了自调光的功能,取得了一定的节能效果。
Dimming function is a development direction of LED Drivers. Dimming LED Drivers can not only adjust lighting effect but also achieve the purpose of energy-saving to some extent. An applied auto-dimming LED driver was designed by using white LED driver IC MP2481 and latest digital-type illuminance sensor BH1710FVC. It uses AT89C2051 as the control chip core,control MP2481 realize dimming function after received and processed the illumin- ance sensor data. Experiment proved that the driver achieved a self-dimming function and certain energy-saving effect.
