LED Devices for Offset Wide Beam Generation
First Claim
1. An apparatus for illuminating a target surface with a predetermined composite pattern of light comprising:
- a light source generating light having a predetermined radiation pattern radiated into a predetermined solid angle;
a reflector onto which light from the light source is incident and which incident light is reflected from the reflector with a single reflection to form a reflection pattern; and
an optic having an inner and outer surface, the reflector occupying a portion of the predetermined solid angle around the light source to the exclusion of the optic at least with respect to any optical function to directly receive a second portion of light from the light source, the optic occupying 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 including substantially all of the second portion of light and being reflected into a predetermined reflection pattern, the inner and/or outer surface of the optic being shaped to refract or direct light which is directly transmitted into the optic from the light source from the first portion of light and/or reflected into the optic from the reflector from the reflected beam into a predetermined beam, which when incident on the target surface forms the predetermined composite pattern of light on the target surface.

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.

24. An apparatus for illuminating a target surface with a predetermined composite pattern of light comprising:
-
a light source generating light having a predetermined radiation pattern radiated into a predetermined solid angle having a first and second zone; reflector means onto which light from the light source is directly incident, the reflector means for reflecting the directly incident light from the second zone with a single reflection to form a predetermined reflected beam; and optic means for refracting or directing substantially all of the light directly transmitted from the light source into the first zone of the predetermined solid angle of the radiation pattern into a refracted/directed beam, where substantially all of the light in the second zone, which comprises all of the remaining portion of the solid angle of the radiation pattern, is directly incident on the reflector means from the light source and is reflected by the reflector means into the predetermined reflected beam, the optic means for refracting or directing the predetermined reflected beam from the reflector to form a composite beam from the refracted/directed and reflected beams, which composite beam when incident on the target surface forms the predetermined composite pattern on the target surface. - View Dependent Claims (25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42)

43. A method for providing an apparatus used with a light source having a predetermined radiation pattern radiated into a predetermined solid angle and used for illuminating a target surface with a predetermined composite pattern of light comprising:
-
providing a reflector onto which light from the light source is incident and which incident light is reflected from the reflector with a single reflection to form a reflection pattern; providing an optic having an inner and outer surface; and disposing the reflector into or next to the optic in an aligned configuration to occupy a portion of the predetermined solid angle around the light source to the exclusion of the optic at least with respect to any optical function to directly receive a second portion of light from the light source, the optic occupying 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 including substantially all of the second portion of light and being reflected into a predetermined reflection pattern, the inner and/or outer surface of the optic being shaped to refract or direct light which is directly transmitted into the optic from the light source from the first portion of light and/or reflected into the optic from the reflector from the reflected beam into a predetermined beam, which when incident on the target surface forms the predetermined composite pattern of light on the target surface.
