Nov. 29, 2019

We know that LED optical lenses are generally divided into "primary lenses" and "secondary lenses". The primary lens actually refers to the light source itself. Let ’s focus on the abbreviation of secondary lens: lens. Common lenses are made of the following materials:

 

PMMA: PMMA lens is the lens commonly used in high-power wall washer lights we are talking about today. The temperature resistance is slightly weak, and the operating temperature cannot exceed 80 degrees Celsius.

 

Silicone: The small size of the silicone lens has high UV resistance, no yellowing, 94% to 96% light transmittance, temperature resistant from -40 to 200, high flexibility and low viscosity, complex shaped products moldable.
