在今年的CES电子展上宝马宣布将为旗下的i8混合动力汽车配备激光大灯。相比这几年流行的LED大灯,这种灯能耗更低、亮度更高、体积更小,是一种非常有前景的新型照明设备。宝马公司表示这种新型大灯在将有效照明距离提升到600米的前提下依旧比LED灯组节省30%的功耗,这对于主要靠电池驱动的车辆是很有意义的。激光大灯系统由位于灯腔后部的激光发生器所射 At this year’s CES Electronics Show, BMW announced that it will equip its i8 hybrid vehicles with laser headlamps. Compared to the popular LED headlamps in recent years, this lamp has lower energy consumption, higher brightness and smaller size, and is a very promising new type of lighting equipment. BMW said the new headlamps will still save 30% more power than LED lights, boosting the effective lighting distance up to 600 meters, which makes sense for mainly battery-powered vehicles. The laser headlamp system is fired by a laser generator located at the rear of the lamp chamber
