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.

Non-glare reflective LED lighting apparatus with heat sink mounting

A lighting apparatus contains a main housing; a reflector disposed within the main housing, and having a front side and a rear side; a heat conducting body comprising at least two heat pipes, wherein a first portion of the at least two heat pipes are parallel to a central axis of the lighting apparatus on the front side of the reflector, and a second portion of each of the at least two heat pipes is in the rear side of the reflector and is thermally coupled to the main housing; a heat conducting head located on the front side of the reflector, and is thermally coupled to the heat conducting body; at least two light-emitting diodes ('LEDs') thermally coupled to the heat conducting body, and being positioned to face the front side of the reflector so that light emitted from the LEDs are directed to said front side.

The present invention relates to a secondary optical lens for a light emitting diode ('LED') light projector, comprising at least one lens unit, wherein the lens unit consists of a refraction portion in the centre and a total internal reflection portion on the outer ring; the central refraction portion has a convex surface on the bottom and is attached with a plurality of micro lenses; the bottom attached with a micro lens array; the total internal reflection portion on the outer ring of the lens unit comprises a cylindrical light incident surface with a slight draft angle, and a total internal reflection surface on the outer side, which adopts a diamondoid polyhedral flake design; and the top of the lens unit is a smooth plane surface used as the light emitting surface.
