Apparatus and method for management of heat in a LED mounted lighting fixture

摘要

The invention provides an apparatus and a method to dissipate heat generated in a LED mounted lighting fixture, comprising an active heat sink with a plurality of integral vents into such active heat sink, wherein the plurality of vents have only two openings, a first opening and a second opening, wherein the active sink is characterized by an induced local air convection current, induced by heat generated at a LED junction in the LED mounted lighting fixture.

主权项

1. A Light Emitting Diode (LED) mounted lighting fixture, comprising:
an LED; and a heat sink for dissipating heat generated by the LED, wherein the LED is mounted on the heat sink, wherein the heat sink comprises a plurality of integral vents each having a cross section, wherein the cross section of each of the plurality of integral vents varies across an entire length of the integral vent such that a top side of longer sides of the heat sink has an oblique angle to a plane parallel to a bottom side of the longer sides, and wherein each of the plurality of integral vents comprises a first opening and a second opening at opposite sides such that a local air convection current throughout the integral vents is induced from the first opening towards the second opening by virtue of the heat generated by the LED.
