Abstract:
1. An illumination system for providing efficient and highly recognizable devices for producing infrared light comprising in combination: a thin circular plate comprised of thermally conductive material having an upper surface and a lower surface; a plurality of rectilinear shaped thermally conductive aluminum boards each having a thickness of about 0.125 inches with a pair of parallel side edges with the face of the edge portion having a diamond shaped heat sink for attachment of at least one LED, and the edge portion having a means for attachment to the plate, the boards being arranged in a configuration with adjacent parallel side edges separated from each other, each board having a vertical portion and a horizontal portion; at least one light emitting diode functioning as a 600 to 900 nm infrared light emitter being coupled to the vertical portion of the board through the diamond shaped heat sink, a thermally conductive paste between the diamond shaped heat sink and the vertical portion of the boards to maximize heat transfer; an optical lens of a generally cylindrical configuration formed as a dome having a closed top end and an open bottom end and comprised of a transparent material, the open bottom end being configured to lie adjacent to the upper surface of the plate; a mounting base of a generally cylindrical configuration with an open top part, a closed bottom part and a side face there around, the top part having a lip adapted to lie adjacent the lower surface of the plate with an aperture and flange extending from the mounting base; a plurality of screw adapted to couple together the rectilinear boards and the plate and the base; a retainer ring adapted to couple together the lens and the plate and the mounting base; and an external electrical source operatively coupled to the system.
