Illumination system
View Patent ↗An illumination system has a mounting plate, a plurality of thermally conductive boards in thermal contact with the mounting plate, a plurality of infrared emitting diodes electrically and thermally communicating with the board strips, an optical lens formed as a translucent dome covering the boards and infrared emitting diodes, and a lamp base operatively coupled to the mounting plate and boards. The infrared emitting diodes receive power from an external electrical source entering the system through the base.
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.
