Abstract

A thermally efficient OGC lamp includes a positive terminal; a negative terminal; a connecting member formed with the negative terminal; a circuit board disposed substantially within the negative terminal; a housing formed with the connecting member; a thermally efficient element filled in the housing; a sealing member disposed on the connecting member; a lens disposed on a bottom of the housing and being distal the connecting member; and a plurality of integrated circuits disposed in the lens for emitting light. The integrated circuits are electrically connected to the circuit board. The circuit board is electrically connected to both the positive terminal and the negative terminal. The thermally efficient element is either oil or wax.

Claims

a positive terminal;

a negative terminal;

a connecting member formed with the negative terminal;

a circuit board disposed substantially within the negative terminal;

a housing formed with the connecting member;

thermally efficient means filled in the housing;

a sealing member disposed on the connecting member;

a lens disposed on a bottom of the housing and being distal the connecting member; and

a plurality of integrated circuits disposed in the lens for emitting light;

wherein the integrated circuits are electrically connected to the circuit board; and

wherein the circuit board is electrically connected to both the positive terminal and the negative terminal.

2. The light source of claim 1, wherein the negative terminal is externally threaded.

3. The light source of claim 1, wherein the housing is formed of glass.

4. The light source of claim 1, wherein the housing is formed of ceramic.

5. The light source of claim 1, wherein the thermally efficient means is oil.

6. The light source of claim 1, wherein the thermally efficient means is wax.

7. The light source of claim 1, wherein the lens is formed of glass.

8. The light source of claim 1, wherein the lens is formed of plastic.
