Abstract

Implementations of the present disclosure provide an adapter for use in a processing chamber. In one implementation, the adapter comprises a hollow body having a first end and a second end opposing the first end, a first block and a second block symmetrically disposed within the hollow body about a longitudinal axis of the body, wherein the first block and the second block define a central opening therebetween, and a retention device disposed in contact with the first and second blocks to confine the movement of the first and second blocks with respect to the hollow body. The central opening is sized so that the first block and the second block provide direct contact with a press seal of the lamp.

First claim

The invention claimed is:

1. A lamp assembly, comprising:
a lamp comprising:
a lamp capsule having a filament disposed therein; and
a press seal extending from the lamp capsule; and

an adapter removably engaged with the lamp, wherein the adapter is a cylindrical hollow body having a first end and a second end opposing the first end, the adapter having a first cut-out and a second cut-out symmetrically disposed about a longitudinal axis of the adapter at the first end, the adapter comprising:
a first block and a second block symmetrically disposed about the longitudinal axis of the adapter, wherein the first block is received within the first cut-out and the second block is received within the second cut-out; and
a retention device disposed around the cylindrical hollow body to confine the movement of the first block and the second block within the cylindrical hollow body, wherein the first block and the second block define an opening to allow passage of the press seal.

2. The lamp assembly of claim 1 , wherein the first block and the second block are two half-cylindrical sections.

3. The lamp assembly of claim 1 , wherein the opening is defined by a recess formed in each of the first block and the second block along a diameter of the first block and a diameter of the second block.

4. The lamp assembly of claim 1 , wherein the first block and the second block make direct contact with the press seal.

5. The lamp assembly of claim 1 , wherein the first block and the second block each has an interior surface that makes direct contact with the press seal, and the interior surface is coated with a light reflecting material.

6. The lamp assembly of claim 1 , wherein the first block and the second block each has one or more grooves formed in an outer peripheral surface of the first block and the second block.

7. The lamp assembly of claim 1 , wherein the adapter has an upper inner surface that surrounds a portion of the lamp capsule, and the upper inner surface is coated with a light reflecting material.

8. The lamp assembly of claim 1 , wherein the adapter has a lower inner surface coated with an insulating layer.

9. A lamp assembly, comprising:
a lamp comprising:
a lamp capsule having a filament disposed therein; and
a press seal extending from the lamp capsule; and

an adapter removably engaged with the lamp, wherein the adapter is a cylindrical hollow body having a first end and a second end opposing the first end, the adapter comprising:
a first block and a second block symmetrically disposed within the cylindrical hollow body about a longitudinal axis of the body, wherein the first block and the second block define an opening to allow passage of the press seal; and
a retention device disposed around the cylindrical hollow body to confine the movement of the first block and the second block within the cylindrical hollow body.

10. The lamp assembly of claim 9 , wherein the first block and the second block are two half-cylindrical sections physically integrated with the cylindrical hollow body.

11. The lamp assembly of claim 9 , wherein the first block and second block are two half-cylindrical sections removably attached to the cylindrical hollow body through the retention device.

12. The lamp assembly of claim 9 , wherein the cylindrical hollow body has one or more grooves formed in an outer peripheral surface of the cylindrical hollow body to receive the retention device.

13. The lamp assembly of claim 9 , wherein the cylindrical hollow body is made of a metal or ceramic material.

14. The lamp assembly of claim 9 , wherein the opening is smaller than the smallest width of the press seal.

15. The lamp assembly of claim 14 , wherein the press seal has a width of about 1 mm to about 5 mm.
