A lamp (10), which is particularly a motor vehicle headlight, comprises a burner (12) for emitting light, which is supported by a holder (16) for mechanically connecting the burner (12) with a socket (14). The holder (16) comprises a metal ring (26) surrounding the burner (12). The metal ring (26) is thermally connected to the burner (12) via a single connecting surface (40), which is in planar contact to the burner (12) over an angle of 350 in circumferential direction. Due to the increased heat transfer to the environment the used materials are less subjected to heat, so that the overall lifetime and the shock resistance of the lamp (10) are increased at the same time.

Provided are heat radiation sheet and method of manufacturing the same. The heat radiation sheet comprising: a first protective layer; a first adhesive member which is disposed on the first protective layer and has one or more through holes; a support member which is disposed on the first adhesive member and has one or more through holes; a second adhesive member which is disposed on the support member and has one or more through holes; a heat radiation member which is disposed on the second adhesive member and has one or more through holes; and a third adhesive member which is disposed on the heat radiation member and comprises a base portion contacting a first surface of the heat radiation member and protrusions protruding from the base portion and inserted into the through holes of the heat radiation member, the through holes of the second adhesive member, the through holes of the support member and the through holes of the first adhesive member, wherein the protrusions of the third adhesive member are at least partially coupled to the first protective layer.

A filament for a light bulb includes a tube and a filament material within the tube, wherein the filament material is configured to be in a liquid state while the light bulb is in use.

A lamp assembly for the lamp assembly adapted for use in a substrate thermal processing chamber to heat the substrate to temperatures up to at least about 1100 C. is disclosed. In one embodiment, the lamp assembly comprises a bulb enclosing at least one radiation generating filament attached to a pair of leads, the bulb having an inner surface and an outer surface, a lamp base configured to receive the pair of leads and at least a portion of the bulb having a surface treatment adapted to reflect light away from the lamp base. In another embodiment, a sleeve covers the lamp base, which has a cross-sectional area less than about 1.2 times the cross-sectional area of the bulb.
