Halogen lampholder and halogen lampholder with heat shield

1. A lamp assembly comprising:

a housing having a front surface, a cavity, and a mounting rod;

a reflector mounted within the cavity, the reflector having a first portion with an opening and a second portion closer to the front surface than the first portion;

a halogen light source removably mounted within the cavity, the opening, and the reflector;

a cap removably secured to the housing;

a lens separate from the reflector and removably disposed between the cap and the housing; and

a heat shield disposed between the lens and the light source.

2. The lamp assembly of claim 1 wherein the heat shield is located between the lens and the reflector.

3. The lamp assembly of claim 1 wherein the heat shield further comprises a central portion aligned with the light source.

4. The lamp assembly of claim 3 wherein the central portion is disk shaped.

5. The lamp assembly of claim 3 wherein the heat shield further comprises an upper flange and a lower flange with a first pair of legs connecting the upper flange to the central portion and a second pair of legs connecting the lower flange to the central portion.

6. The lamp assembly of claim 3 wherein the central portion prevents heat generated by the light source from directly impacting a central section of the lens.

7. The lamp assembly of claim 5 wherein heat generated by the light source and impacting the central portion is dissipated through the first and second pair of legs and the upper and lower flanges.

8. The lamp assembly of claim 7 wherein the upper and lower flanges transfer heat into the cap.

9. The lamp assembly of claim 1 wherein the first portion of the reflector is parabolic in shape.

10. The lamp assembly of claim 1 wherein the reflector further comprises a midpoint along the length of the reflector between the opening and the front surface of the housing, wherein the light source extends proximate the mid-point.

11. The lamp assembly of claim 1 wherein the first portion of the reflector is parabolic in shape and the second portion of the reflector is cylindrical in shape and wherein the light source is maintained within an area surrounded by the parabolic portion.

12. The lamp assembly of claim 1 wherein the lens is ceramic.

13. The lamp assembly of claim 1 wherein the light source and the lens each further comprise a longitudinal axis and wherein the light source longitudinal axis is arranged generally perpendicular to the lens longitudinal axis.

14. The lamp assembly of claim 1 wherein the housing is pivotably secured to the mounting rod.

15. The lamp assembly of claim 1 further comprising a gasket disposed between the housing and the cap and wherein the heat shield is at least partially disposed within the gasket.

16. The lamp assembly of claim 1 wherein the heat shield covers at least approximately 25% of the lens.

17. A lamp assembly comprising:

a housing having a front surface, a cavity, and a mounting rod;

a reflector mounted within the cavity and having a first parabolic portion with an opening and a second portion closer to the front surface than the first parabolic portion;

a halogen light source removably mounted within the cavity, the opening, and the reflector;

a cap removably secured to the housing;

a lens separate from the reflector and removably disposed between the cap and the housing; and

a heat shield disposed between the lens and the light source,

wherein the second portion is generally cylindrical in shape.

18. The lamp assembly of claim 17 wherein a diameter of the second portion increases from the first portion to the front surface.

19. The lamp assembly of claim 1 wherein the heat shield comprises a step spacing the heat shield from the lens.
