Abstract
A heat sink for use with a high output LED light source is disclosed. The heat sink is used with an LED and conical reflector. The heat sink has a cylindrical back end holding the light emitting diode. The heat sink includes a conically shaped wall having an inner and outer surface and an open front end. The open front end has a rim with notches. The reflector has a front flat surface with arms which are fixed in the notches with a fastener. The heat sink includes a plurality of slits formed on the inner and outer surfaces extending between the back and front ends. A plurality of vanes extend radially from the inner surface. The heat sink is fabricated from a thermally conductive material. The conical shape of the heat sink, the slits and vanes increases exposed surface area to assist in dissipating heat generated from the LED.
Claims10
A heat sink for use in conjunction with a light emitting diode light source, the heat sink comprising:
- a base member having electrical connections;
- a wall having a conically shaped portion, the conically shaped portion of the wall having an outer surface, an inner surface, a back end having a mounting aperture for a light emitting diode, an opposite open front end, and a plurality of slits through the conically shaped portion;
- and
- a plurality of vanes extending radially inward from the inner surface.
A heat sink for use in conjunction with a light emitting diode light source, the heat sink comprising:
- a wall having a conically shaped portion, the conically shaped portion having an open front end, a back end opposite the front end and a plurality of slits through the conically shaped portion, wherein the wall is fabricated of a highly thermally conductive material;
- and
- a rectangular box-shaped base member, held by the back end and adapted so that a substrate plate including a light emitting diode may be attached to the base member.
