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.

21. 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 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 light produced by the light emitting diode, wherein the second side comprises; a bulbous region that is free from abrupt changes in form; and a base region that is substantially flat and that meets the bulbous region to form a corner between the bulbous region and the base region that peripherally circumscribes the bulbous region. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28)

29. 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 light produced by the light emitting diode; and a reflector disposed between the second side and the light emitting diode, wherein the second side of the optic substantially consists of; a base region; a region that rises above the base region and that is free from abrupt changes in form; and a corner formed between the base region and the region. - View Dependent Claims (30, 31, 32, 33)

34. A light source comprising:
-
a light emitting diode; and an optic that is positioned to manage light emitted by the light emitting diode and that comprises; a first side that is oriented towards the light emitting diode; a second side that opposes the first side and that comprises; a corner that extends peripherally with respect to the light emitting diode; and a surface region that is circumscribed by the corner, wherein all of the surface region that is circumscribed by the corner is smooth and free from abrupt changes in form; and a reflector disposed between the second side and the light emitting diode. - View Dependent Claims (35, 36, 37, 38, 39, 40)
