LED LIGHTING FIXTURES

摘要

LED lighting systems employing plano optics, direct dissipation heat sinks, and linear AC direct current drivers are disclosed. The heat sink is configured to provide thermal management for the LED lights and AC linear current driver circuit elements, as well as to provide a means for holding lenses having diffractive optical elements. The LED lighting systems are compact, energy efficient, and may be used in many conventional incandescent or fluorescent lighting applications. Lenses having diffractive optical elements are designed to redirect light radiated from the LEDs into other directions.

主权项

1. A lighting system comprising:
an elongated heat sink, the heat sink having a back surface configured for mounting, the heat sink further comprising an internal cavity running along the length of the heat sink, the inner cavity having a generally flat bottom surface and two walls extending perpendicular from the generally flat bottom surface, each wall having a groove running along the length of the heat sink, each groove spaced equidistant from the flat bottom surface; a printed circuit board assembly comprising:
a printed circuit board mounted on the generally flat bottom section of the heat sink;one or more light emitting diodes (“LEDs”) mounted on the printed circuit board;one or more electrical devices configured to energize the LEDs;a plurality of wire connectors configured for electrically coupling power cables to the printed circuit board a lens mounted in the grooves of the heat sink; a first end cap coupled to one end of the elongated heat sink; and, a second end cap coupled to the other end of the elongated heat sink, the one end opposite that of the other end.
