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.
