摘要
传统汽车远光开启会引发其他交通参与者眩目,造成夜间行车的安全隐患,并加速驾驶疲劳。针对上述问题,提出一种反射式矩阵LED前照灯,通过控制前照灯内一个或多个LED反射式光电模组的开关输出不同区域的无眩目远光分布,通过Lucid Shape软件完成光学仿真。其结果表明:该设计既产生普通远光分布,满足法规GB 25991-2010要求;又产生含"暗区"的光分布,满足ECE R123要求,实现无眩目汽车远光照明。
The traditional automotive high beam glares other traffic participants,which creates the night driving discomfort,and accelerates driver fatigue. To solve this problem,a kind of matrix LED module by reflection was put forward. Under controlling each LEDs’ circuit,the headlamp could output a variety of light distribution,and avoid to glare others. By optical simulation of Lucid Shape software,the results indicates that the matrix LED high beam can not only produce ordinary high beam distribution,meet the regulatory requirements of GB 25991-2010,but also can produce the light distribution with dark areas,meet the regulatory requirements of ECE R123,and realize the non-glare vehicle high light illumination.
