What are the causes of yellowing in streetlight lenses?

Entering the 21st century, lens-based lighting is gradually replacing traditional illumination, with street‑light lenses being among the most widely used applications—its widespread adoption is hardly news. However, as these lenses become more prevalent, issues inevitably arise due to factors such as material quality, human error, or physiological considerations. As a critical component in the manufacture of street‑light lenses, the quality of the LED chips largely determines the overall performance and reliability of the lenses.

What causes LED lenses to turn yellow and develop cracks?

An LED lens is a type of optical lens commonly used in lighting, chemical instruments, and other applications. So, what causes LED lenses to turn yellow? EAs-ItRxSA-bAaz6rhaUWg.jpg 1. Yellowing due to sulfidation of the LED lens coating. After sulfidation occurs, the functional area of the LED lens may darken, leading to a gradual reduction in luminous flux and noticeable color temperature drift. Additionally, the electrical conductivity of silver sulfide increases with rising temperature, making leakage currents more likely during operation.
