1	LED汽车前照灯:眩光与显色性显示文摘由于发光二极管(LEDs)的光输出有了迅速的提高,人们开始认真地关注将LED应用于汽车前照灯这一课题。本项研究分析检验了LED对迎面司机所造成的不舒适眩光及对逆反射交通指示材料显色性的影响。在两种情况下,对使用LED与将传统钨丝灯更改为高强度气体放电(HID)灯的情况下上述属性的改变进行了对比。详细来讲,实验中分别使用了7个LED光源(前照灯用)和17个现有的HID前照灯,通过比较他们的色度学参数来分析不舒适眩光所受影响。类似的,对显色性影响的分析是通过比较使用两种不同光源时7种红色逆反射材料(目前在交通控制中以红色信号传递信息最多)的色度学参数而获得的。通过分析,对现有的LED产品系列有如下结论:1)比现有的HID系统产生更多的不舒适眩光,实质上比卤素灯系统产生了更多的不舒适眩光;2)显色指数可接受;3)对红色逆反射材料的视亮度没有明显的影响。	Sivak M 林燕丹	2006	中国照明电器2006，，5：	2
