A lighting apparatus using at least one light-emitting diode ("LED"), back-reflecting collection optics for LEDs, and an improved heat sink mounting ap-paratus which promotes efficient heat dissipation generat-ed from the LED while minimizing light obstruction and glare. The lighting apparatus contains a main housing; a reflector disposed within the main housing, the reflector having a front side and a rear side; a top rim thermally coupled to one end of the main housing; a heat conducting body positioned to face the front side of the reflector, the heat conducting body comprising a heat pipe thermally coupled to the top rim; at least one light-emitting diode thermally coupled to the heat conducting body, the at least one light-emitting diode being positioned to face directly at the front side of the reflector so that light emitted from the at least one light-emitting diode is directed to the front side of the reflector. |
