Illumination system
View Patent ↗An illumination system has a mounting plate, a plurality of thermally conductive circuit boards in thermal contact with the mounting plate, a plurality of light emitting diodes electrically and thermally communicating with the circuit board strips, an optical lens formed as a translucent dome covering the circuit boards and light emitting diodes, and a lamp base operatively coupled to the mounting plate and circuit boards. The light emitting diodes receive power from an external electrical source entering the system through the base and the circuit boards.
1. 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.
