Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
The invention claimed is: 1. A lighting apparatus for preferential-side illumination from an LED light emitter having an axis, the apparatus having a first lens over the emitter and a second lens over the first lens, the apparatus comprising: 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 which includes: a refracting…
