LED devices for offset wide beam generation
First Claim
1. A light source comprising:
- a light emitting diode; and
an optic that is disposed adjacent the light emitting diode and that comprises;
a first side oriented to receive light produced by the light emitting diode;
a second side that opposes the first side and that is oriented to emit the light received by the optic via the first side; and
a reflector disposed between the second side and the light emitting diode so as to reflect a portion of the light produced by the light emitting diode, the reflector having a curved shape and extending in an azimuthal angle of approximately 180 degrees about the light emitting diode,wherein the second side comprises;
a base region that is substantially flat and that meets a bulbous region to form a corner between the bulbous region and the base region, wherein the corner peripherally circumscribes the bulbous region.

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.

9. A light source comprising:
-
a light emitting diode; and an optic that is disposed adjacent the light emitting diode and that comprises; a first side positioned to receive light produced by the light emitting diode; a second side that is disposed opposite the first side and that is positioned to emit the light produced by the light emitting diode; and a reflector disposed between the second side and the light emitting diode, the reflector having a curved shape and extending in an azimuthal angle greater than 165 degrees and less than 270 degrees about the light emitting diode, wherein the second side of the optic comprises; a base region and a bulbous region; and wherein an end of the reflector is disposed in a notch, the notch located in the bulbous region and on the first side of the optic, wherein the notch terminates before reaching the second side of the optic. - View Dependent Claims (10, 11, 12, 13)
