摘　　要：本文在大量研究基础上,提出一种专门针对LED模组的在线检测方案和设备,一方面可对LED模组光色电参数100%全检和自动分级;另一方面该还可对LED模组中的每颗LED芯片发光面积做出检测和合格判定,保证了车灯模组之间的光色一致性,而且本方案特有的机器视觉定位系统可实现模组的自动定位,大大提高了检测效率。In this paper,an on-line test solution and equipment for automotive LED modules are proposed,which can not only obtain the photometric,colorimetric and electric quantities for all LED modules and classify them according to the measurement results,but also,the lighting situation of every single chip in a module can be assessed,ensuring the optical consistency of the LED modules. Besides,the solution also adopts particular machine vision to realize the automatic positioning of the measured modules,greatly improving the test speed and efficiency.
