Stucture in lens,
Filling similar materials and refractive index with LED light source packaging materials and light distribution lens material between the light incident surface of the light distributing lens and the light emitting surface of the LED light source, Then there is no air space between the light exit surface of the LED light source and the light incident surface of the light distribution lens, which greatly reduces the reflection loss of the light interface.
1. Specially designed for optical properties.
2. Before the lens is installed, a specific colloid is filled in the lens chips slot and dried. After installation, the colloid completely wraps the light exit surface so that there is no gap between the light exit surface and the lens incident surface.
