Abstract

An integrated reflector lamp (1) comprising an outer wall (3,9,13) enclosing a light source (6), a metal reflector (7), and an electronic power supply unit (4) to which the light source (6) is connected, wherein the reflector (7) extends between the light source (6) and the electronic power supply unit (4). Said outer wall (3,9,13) comprises a substantially conical portion (3) and a transparent portion (9) that covers the opening of said conical portion (3). The reflector (7) also covers the opening of said conical portion (3). The reflector (7) and the transparent portion (9) enclose the light source (6), the reflector (7) and the conical portion (3) enclose the electronic power supply unit (4).

Claims

1. An integrated reflector lamp comprising

an outer wall enclosing a light source having a discharge vessel, a base and an outer envelope around the discharge vessel;

a reflector comprising a body, wherein the body is entirely made of a metal to transfer heat generated by the light source to the outer wall; and

an electronic power supply unit connected to the light source, wherein the reflector extends between the light source and the electronic power supply unit, and wherein the base has an elevation that extends into the outer envelope for centering the discharge vessel, and wherein a portion of the elevation surrounded by the outer envelope contacts the outer envelope.

2. The integrated reflector lamp according to claim 1, wherein said outer wall comprises a substantially conical portion and a transparent portion that covers the opening of said conical portion, and wherein the reflector covers the opening of said conical portion.

3. The integrated reflector lamp according to claim 2, wherein the light source extends coaxially relative to the reflector.

4. The integrated reflector lamp according to claim 2, wherein the reflector and the transparent portion enclose the light source hermetically.

5. The integrated reflector lamp according to claim 2, wherein the reflector and the conical portion enclose the electronic power supply unit.

6. The integrated reflector lamp according to claim 1, further comprising a heat shield extending substantially transversely between the reflector and the electronic power supply unit.

7. The integrated reflector lamp according to claim 6, wherein said heat shield is a PCB.

8. The integrated reflector lamp according to claim 6, wherein said heat shield divides the lamp into two compartments in a substantially airtight manner.

9. The integrated reflector lamp according to claim 1, wherein said light source is a high-pressure discharge light source.

10. The integrated reflector lamp according to claim 1, wherein said light source is a halogen light source.

11. The integrated reflector lamp of claim 1, wherein the reflector comprises a base having a recess for receiving the light source.

12. The integrated reflector lamp of claim 1, wherein the light source further comprises an enamel ring surrounding the elevation.

13. The integrated reflector lamp of claim 1, wherein the reflector further comprises a reflective coating to improve reflective characteristics of the reflector.

14. The integrated reflector lamp of claim 1, wherein the metal includes at least one of steel, aluminum and copper.
