Factors that cause the LED light source to turn black
1. Vulcanization, chlorination, bromination
Touching sulfur-containing gas on the silver-plated layer on the LED bracket will generate silver sulfide, and touching acidic nitrogen-containing chlorine and bromine gas will generate light-sensitive silver halide, which will cause the light source to blacken and fail. Light source sulfur/chlorine/bromination may occur in every link of the production, storage, aging, and use of LED light sources and lamps. After the darkening of the light source is diagnosed as sulfur/chlorine/bromination, the customer should select a detailed sulfur discharge plan based on the stage of sulfur/chlorine/bromination. At present, Xinqin Lighting has launched sulfur/chlorine/bromine detection items: lamp sulfur/chlorine/bromine (including built-in power supply), lamp sulfur/chlorine/bromine (except power supply), power supply sulfur/chlorine/bromine,…
