Patent ID: 6991351

Claim:
An illumination system for providing efficient and highly recognizable devices for producing 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 “L” shaped thermally conductive circuit boards each having an internal face, an external face, a pair of parallel side edges, a vertical portion and a horizontal portion and a bend there between, with the external face of the vertical portion having a means for attachment of at least one LED, and the horizontal portion having a means for attachment to the plate, the circuit boards being arranged in a configuration with adjacent parallel side edges separated from each other; at least one light emitting diode functioning as a light emitter being coupled to the vertical portion of the circuit board with means 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 rivets adapted to couple together the circuit 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.
