Description

technical field [0001] The invention relates to a light source detection device technology, in particular to an online light source detection device. Background technique [0002] In order to ensure the quality of light source products, a series of performance tests are required after the light source assembly is completed, including light, color, and electrical performance, high and low voltage aging, electromagnetic compatibility immunity and switch reliability tests. Due to the different test methods, required test equipment and complexity, it is not possible to fully test the above-mentioned key performances for each light source product in the existing production process. At present, only the photochromic performance of each light source can be fully inspected, that is, the online photochromic detection system of the light source is used, and it is difficult to realize online testing of other performances during the production process. In order to control quality, manu...
