Compact reflector lamp and method for its production

1 . A compact reflector lamp having a lamp stem, from which outer power supply lines are passed, and a lamp vessel which has a lamp vessel section which is closely surrounded by a reflective substrate material in the form of a reflector.

2 . The reflector lamp as claimed in claim 1 , the reflective substrate material being a mirror-coated sheet or metal sheet or a mirror-coated film.

3 . The reflector lamp as claimed in claim 2 , the substrate material being made from aluminum.

4 . The reflector lamp as claimed in claim 1 , which has a lamp neck in the form of a constriction between the lamp vessel and the lamp stem, the reflective substrate material closely surrounding this lamp neck and in the process being supported on the lamp stem.

5 . The reflector lamp as claimed in claim 1 , the lamp vessel section surrounded by the reflective substrate material tapering in the direction towards the lamp neck, and, at the end opposite the lamp stem, the lamp vessel having a bowl, through which light is emitted during operation of the lamp.

6 . The reflector lamp as claimed in claim 1 , the lamp vessel section surrounded by the reflective substrate material corresponding to one half of the length of the lamp vessel.

7 . The reflector lamp as claimed in claim 1 in the form of an incandescent lamp.

8 . The reflector lamp as claimed in claim 1 in the form of a discharge lamp.

9 . A method for producing a reflector lamp having the features as claimed in claim 1 , having the following method steps:

provision of the lamp vessel including the lamp stem,

provision of a previously mirror-coated material as the reflective substrate material,

cutting the reflective substrate material to size,

integrally forming the reflective substrate material on the lamp vessel section provided for this purpose.

10 . The method as claimed in claim 9 , in which, once the reflective substrate material has been integrally formed, the two abutting edges of said substrate material are joined, for example by means of welding, by being bent back or being pushed through.

11 . The method as claimed in claim 9 , in which two flap halves are formed from the substrate material which are connected to one another at their seam once they have been integrally formed on the lamp vessel.

12 . The reflector lamp as claimed in claim 2 , which has a lamp neck in the form of a constriction between the lamp vessel and the lamp stem, the reflective substrate material closely surrounding this lamp neck and in the process being supported on the lamp stem.

13 . The reflector lamp as claimed in claim 3 , which has a lamp neck in the form of a constriction between the lamp vessel and the lamp stem, the reflective substrate material closely surrounding this lamp neck and in the process being supported on the lamp stem.
