## Abstract

A reflector lamp having a reflector which has a reflector neck and defines a reflector axis, and an electric lamp fixed in the reflector neck by a metallic holder, in which a section of the metallic holder is arranged, secured against rotations about the axis, in a cutout in the reflector neck and projects from the neck through this cutout, a shoulder in the region of the reflector neck a is designed as a depth stop for the metallic holder in the direction of the reflector axis, the lamp has a metallic base shell is provided with a thread and for which the outer wall of the reflector neck forms a stop surface, and there is a screwed connection between the base shell and the part, projecting from the reflector neck, of the section, arranged in the cutout of the reflector neck, of the metallic holder.

## Claims

### Claim 1

A reflector lamp having a reflector which has a reflector neck and defines a reflector axis, and having an electric lamp which is fixed in the reflector neck by means of a metallic holder, wherein
a section of the metallic holder is arranged, secured against rotations about the reflector axis, in a cutout in the reflector neck and projects from the reflector neck through this cutout,
there is arranged in the region of the reflector neck a shoulder which is designed as a depth stop for the metallic holder in the direction of the reflector axis,
the reflector lamp has a metallic base shell which is provided with a thread and for which the outer wall of the reflector neck forms a stop surface, and
there is a screwed connection between the base shell and the part, projecting from the reflector neck, of the section, arranged in the cutout of the reflector neck, of the metallic holder.

### Claim 2 (depends on 1)

The reflector lamp as claimed in claim 1, wherein both the shape of the cutout in the reflector neck and the section, arranged in the cutout of the reflector neck, of the metallic holder have a shape which is not rotationally symmetrical with reference to the reflector axis, and the dimensions of the cutout and of the section are coordinated with one another.

### Claim 3 (depends on 1)

The reflector lamp as claimed in claim 1, wherein the section, arranged in the cutout in the reflector neck, of the metallic holder is designed as a sleeve which has at least two mutually opposite side walls running parallel to one another, and the reflector neck has at least two mutually opposite inner walls in the region of its cutout, the abovementioned side walls of the sleeve bearing against the inner walls.

### Claim 4 (depends on 1)

The reflector lamp as claimed in claim 1, wherein the metallic holder has at least two lugs which are angled off perpendicular to the reflector axis and bear against the shoulder.

### Claim 5 (depends on 1)

The reflector lamp as claimed in claim 1, wherein the part, projecting from the reflector neck, of the section, arranged in the cutout in the reflector neck, of the metallic holder has knobs which bear against the inner wall of the base shell and engage in the thread of the base shell.

### Claim 6 (depends on 1)

The reflector lamp as claimed in claim 1, wherein the outside of the reflector neck is provided with a surface running obliquely with reference to the reflector axis.

### Claim 7 (depends on 1)

The reflector lamp as claimed in claim 1, wherein the base shell is fixed on the reflector neck by an adhesive or by a crimp connection.

### Claim 8 (depends on 1)

The reflector lamp as claimed in claim 1, wherein a first supply lead, projecting from the lamp, is connected in an electrically conducting fashion to the metallic holder, and a second supply lead, projecting from the lamp, is connected in an electrically conducting fashion to a contact plate of the base shell.
