A lighting apparatus using at least one light-emitting diode (“LED”), back-reflecting collection optics for LEDs, and an improved heat sink mounting apparatus which promotes efficient heat dissipation generated 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. |

1. A lighting apparatus comprising:
a main housing having a top end and a bottom end; a plastic housing having a top end and a bottom end, the top end of the plastic housing coupled to the bottom end of the main housing, and a lamp base coupled to the bottom end of the plastic housing; a reflector disposed within the main housing, the reflector having a front side and a rear side; a circular top rim having a top platform, a bottom platform and two sidewalls that are each coupled between adjacent side edges of the top and bottom platforms, the circular top rim being coupled to the top end of the main housing, wherein one of the two sidewalls includes a plurality of sidewall slots; a substantially S-shaped heat conducting body positioned to face the front side of the reflector and disposed within the circular top rim and between the top and the bottom platforms, the heat conducting body comprising a heat pipe thermally coupled to the circular top rim, the heat conducting body comprising a middle portion that is bar-shaped, and curved wing portions extending from the middle portion, each of the curved wing portions coupled to the circular top rim, wherein the circular top rim has slots in the top platform which permit each curved wing portion to fit and couple within the slots, wherein the plurality of sidewall slots are configured to permit the curved wing portions to fit and couple within the plurality of sidewall slots, and wherein the heat pipe is located in the middle portion and at least one of the curved wing portions; and 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. |
