LED Devices for Offset Wide Beam Generation
First Claim
1. A luminaire comprising:
- a housing comprising an area that is operative to emit light towards an area to be illuminated; and
a plurality of arrays of light sources, each array mounted to a respective substrate, the substrates mounted adjacent one another at the area of the housing,wherein each light source comprises;
at least one light emitting diode;
an optic covering the at least one light emitting diode and comprising an environmentally exposed exterior surface that protects the at least one light emitting diode from environmental exposure and that has a debris shedding smooth shape; and
a mirror disposed between the exterior surface and the at least one light emitting diode.

Abstract
A light source is combined with an optic and a reflector. Light incident onto to the reflector is reflected with a single reflection. The reflector occupies a portion of a solid angle around the light source to the exclusion of the optic at least with respect to any optical function. The reflector directly receives a second portion of light. The optic occupies substantially all of the remaining portion of the predetermined solid angle to directly receive a first portion of light from the light source. A reflected beam from the reflector is reflected into a predetermined reflection pattern. The inner and/or outer surface of the optic is shaped to refract or direct light which is directly transmitted into the optic from the light source from a first portion of light and/or reflected into the optic from the reflector from the reflected beam into a predetermined beam.
