Abstract

A lamp assembly (10) has a base (12) with an axially extending post 14 having a first surface 16. The base and the post are thermally conductive. A light emitting diode (18) is operatively affixed to the first surface (16). A reflector (20) is in optical communication with the light emitting diode (18) and the reflector (20) is mechanically fixed to the base 12. Electrical connections (22, 24) extend through the base (12) to the light emitting diode (18).

Claims

1. A lamp assembly comprising:

a base having an axially extending post with a first surface, said base being thermally conductive;

a single light emitting diode operatively affixed to said first surface;

a reflector in optical communication with said light emitting diode, said reflector being mechanically fixed to said thermally conductive base; and

electrical connections extending through said base to said light emitting diode.

2. The lamp assembly of claim 1 wherein said mechanical fixation comprises said reflector and said base being insert-molded together.

3. The lamp assembly of claim 1 wherein said mechanical fixation comprises said base and said reflector being compression-fitted together.

4. The lamp assembly of claim 1 wherein said mechanical fixation comprises said reflector and said base being glued together.

5. The lamp assembly of claim 1 wherein a housing is attached to said base and said housing includes electrical circuitry for powering said light emitting diode.

6. The lamp assembly of claim 1 wherein said base has at least one surface exposed for heat dissipation.

7. The lamp assembly of claim 1 wherein said light emitting diode is substantially a side emitting diode.

8. The lamp assembly of claim 2 wherein said light emitting diode is substantially a side emitting diode.

9. The lamp assembly of claim 3 wherein said light emitting diode is substantially a side emitting diode.

10. The lamp assembly of claim 4 wherein said light emitting diode is substantially a side emitting diode.

11. The lamp assembly of claim 5 wherein said light emitting diode is substantially a side emitting diode.

12. The lamp assembly of claim 6 wherein said light emitting diode is substantially a side emitting diode.
