Patent ID: 7503669

Claim:
A portable luminaire comprising: an optical module including, at least one light emitting diode (LED) that emits light with a wide divergence; a transparent window to transmit light outside the optical module; and a non-imaging optical element (NIO) that collects light emitted by the LED with high efficiency, compresses the collected light and directs the compressed light through the transparent window with a precalculated intensity distribution across a pattern, wherein the NIO further includes, a refractive member located around a LED optical axis having a first end that collects light from the LED and a second end opposite the first end to transmit light; a total internal reflection member located around the refractive member, wherein the TIR member has a first end to collect light and a second end opposite the first end to transmit light, and a wall formed therebetween wherein an outside surface of the wall is curved to reflect light through the second end of the refractive member with a precalculated divergence that does not exceed a maximum angle; and wherein the refractive member and the TIR member are integrated into a single transparent element having a mutual focal point; a base supporting the NIO element, wherein the base is a heat sink for the at least one LED; and a housing connected to the base, wherein the housing includes a controller therein to provide remote control operation of the optical module, a leveling mechanism to adjust the optical module with respect to a horizontal surface, and a rechargeable power source that is connected to the at least one LED through the controller.
