摘要
随着汽车工业的快速发展,对汽车节能减排及安全性能的要求越来越高,汽车照明系统的节能与安全问题已成为该领域研究的热点。作为第四代车用光源,LED有很多优于其他传统光源的特点。为此分析了车用LED照明的可行性和先进性,介绍了其典型的驱动电路,并着重研究了LED以及AFS在汽车前照灯上应用现状。介绍了车用LED照明面临的问题及应对措施,并对其未来发展进行了展望。
With the rapid development of modern automobile industry, the request for energy saving and pollutant reduction and security in automobile is much bigger, so the energy conservation and security of automobile lighting systems has become hot spot in this research field. As the fourth generation light sources for cars, LED has much more advantageous characteristics than other traditional light source. Therefore, the feasibility and advanced nature of LED lighting engineering in automobile is analyzed and the typical driving circuits are introduced, emphasizing the present application of LED and AFS to the automotive headlamps. A list of problems and solutions, which automotive LED illumination technology is facing, are pointed out, prospecting the development of automotive LED illumination technology in future.
