汽车外部照明装置振动前后配光图比较

Difference of the Photometric Characteristics of a Kind of Automotive Lighting Device Tested Before And After the Libration Test

根据详细的振动要求,我们测试了某款汽车外部照明装置在振动前后的配光数据变化,根据测试结果得知灯座和灯体一体化结构的灯具可以承受汽车的振动等情况而保持配光性能不变。

According to the details of libration requirements, the photometric characteristics of a kind of automotive lighting device is tested before and after the libration test. We draw the conclusion that the photometric characteristics of the lamp incorporating with lampholder can keep unchangeable after the automotive libration.
