Light aging test is the process of simulating various factors (light, water, heat) involved in the aging of a product under real environmental conditions, and strengthening the experiment under corresponding conditions. At the same time, according to usage requirements, the product's service life is reasonably predicted.
The core parameter of light aging test is light, which is mainly divided into four types according to different light sources: UV, xenon lamp, carbon arc lamp, and metal halogen lamp
