In the context of the lighting, frosted lens refers to a specialized type of lens that is designed to conceal LED diodes while still allowing for effective light transmission. It is particularly useful in applications where minimizing glare from the diodes is crucial, such as parking garages, freezers, and retail spaces. The primary function of a frosted lens is to diffuse the light emitted by the diodes, resulting in a softer and more evenly distributed illumination.
