Abstract
A thermally conducting reflector is employed to serve as dual-use thermal conductor and light reflector for collimating a multi-chip LED array. The thermally conducting reflector consists of a heat sink, item, a reflector made of a thermally conducting and optically reflective material such as aluminum, item, a transparent cover, item, and lamp base that is electrically isolating, item and a common lighting electrical connector, item, illustrated as an Edison type screw base. The novelty in the present invention is how the items are structured to work together to dissipate heat.
Claims14
A thermally conducting reflector device employed to serve as dual-use thermal conductor and light reflector for collimating a multi-chip LED array comprising:
- a heat sink;
- a reflector made of a thermally conducting and optically reflective material such as aluminum;
- a transparent cover;
- a lamp base that is electrically isolating;
- and
- a common lighting electrical connector.
The device of claim 15, further comprising
- one of a plurality of multi-control primitives used to optically guide, direct, and collimate the light;
- wherein a light bundle incident upon the multi-control primitive, reflects through operation of the Bezier spline reflector at points respectively;
- a light bundle emerges from the multi-control device with light which is spatially more uniform;
- and
- the composite light beam produced through the combined effect of the multi-control primitives is a uniform light distribution.
