Abstract
A lamp comprises an LED light source for emitting light. A combined heat sink and reflector is thermally coupled to the LED light source. The heat sink and reflector comprise an internal surface for reflecting the light and an exterior surface. The internal surface and the external surface are uncovered such that heat is dissipated from the interior surface and the exterior surface.
Claims21
A lamp comprising:
- an LED light source for emitting light;
- a heat sink and reflector surrounding the LED light source, the heat sink and reflector comprising an interior surface for reflecting the light and an exterior surface, an optical element disposed in the heat sink and reflector that receives all of the light emitted from the LED light source for shaping and mixing the light emitted from the LED light source, the optical element being positioned such that the interior surface and the exterior surface of the heat sink and reflector are uncovered such that heat is dissipated from the interior surface and the exterior surface.
