Is the blackening of the LED light source due to chemical incompatibility, oxidation, carbonization, sulfuration, chlorination, or bromination? The professionals at Benwei Lighting will reveal the solution!
The blackening of LED light sources is an issue that big LED firms often face. The light source's apparent blackening is just that—an appearance. The LED light source will become black for a variety of reasons, including sulfidation, chlorination, bromination, oxidation, carbonization, and chemical incompatibility. The majority of LED firms often depend on experience and educated guesses when doing blackening failure analysis since they lack professional testing equipment and employees. Benwei lighting experts developed the preliminary diagnosis of LED light source blackening as a response to this phenomenon, with the goal of helping customers quickly, affordably, and accurately characterize the cause of LED light source blackening (whether it is vulcanization, chlorination, or bromination or not) within two days.
Bromination, chlorination, and sulfurization
When sulfur-containing gas comes into contact with the silver-plated layer on the LED bracket, it will produce silver sulfide, and when acidic nitrogen-containing chlorine and bromine gases come into contact with it, it will produce light-sensitive silver halide, which will turn the light source black and cause it to malfunction. Every stage of the manufacture, storage, aging, and usage of LED light sources and lamps is susceptible to sulfur, chlorine, and bromination of light sources. The client should choose a particular sulfur removal plan in accordance with the procedure of sulfur, chlorine, and bromination once the cause of the blackening of the light source has been determined to be sulfur, chlorine, or bromination. The following are some of the current sulfur, chlorine, and bromine detection tools made available by Benwei Lighting Experts: Sulfur, chlorine, and bromine exhaust from lamps (including built-in power supply), Sulfur, chlorine, and bromine exhaust from lamps (except external power supply), Sulfur, chlorine, and bromine exhaust from power supply, Sulfur, chlorine, and bromine exhaust from auxiliary materials, Sulfur, chlorine, and bromine exhaust from packaging workshop, Since gases including sulfur, chlorine, or bromine may enter the light source via cracks in the bracket or silica gel, Benwei lighting specialists have also started an air tightness testing program to help clients enhance the specifications for incoming light sources.
