Multi-lens LED-array optic system
Abstract:
Lighting apparatus having a first lens over the LED emitter and a second lens over the first lens, and including: a first optical surface which is a first-lens outer surface configured to refract light from the emitter; a second optical surface which is a second-lens inner surface spaced from the first optical surface; and a third optical surface which is a second-lens outer surface configured to refract light from the second optical surface toward a preferential side. One embodiment includes asymmetric primary and secondary lenses.
