汽车LED前照灯驱动电路设计方案

The design scheme of automobile LED headlamp driving circuit

近年来随着中国政府大力推进实施节能减排政策,汽车LED照明技术成为重要的节能减排技术之一。由于LED节能、环保、高亮度、高寿命特点,使得LED照明越来越多的运用到汽车上。前照灯作为汽车上高功率电器之一,LED照明技术必将在前照灯中取代卤素灯泡的位置。驱动电路设计是汽车LED前照灯设计中的核心部分,掌握汽车LED前照灯驱动电路的设计方法显得尤其重要。

In recent years,with the Chinese government vigorously promote the implementation of energy conservation and emissions reduction policy,car LED lighting technology has become one of important technology for energy conservation and emissions reduction,due to the LED energy saving,environmental protection,high brightness,high service life characteristics,LED lighting,more and more applied to cars.As one of the high power electric,LED lighting technology will replace the position of the halogen bulbs in headlamps.Drive circuit design is the core part in the design of automobile LED headlamps,master automobile LED headlamps drive circuit design method is especially important.
