Abstract

The invention relates to a lamp for a light system, which lamp comprises at least: a lamp envelope (1) in which at least one electrical radiant source is enclosed and from which project at least two current supply means, a lamp base (2) that has at least one part by which the lamp envelope is fixed to the lamp base, and a reference element (3, 4) that is arranged on the lamp base wherein the material of the part of the lamp base by which the lamp base (2) is fixed to the lamp envelope (1) is composed of a plastics material or a mixture of plastics materials that is resistant to high temperatures.

Claims

1. A lamp for a light system, comprising at least:

a lamp envelope (1) in which at least one electrical radiant source is enclosed and from which project at least two current supply means,

a lamp base (2) that has a part by which the lamp base (2) is fixed to the lamp envelope (1), and

a reference element (4) that is arranged on the lamp base (2),

wherein the material of the part of the lamp base by which the lamp base (2) is fixed to the lamp envelope (1) is composed of a plastics material or a mixture of plastics materials that is resistant to high temperatures.

2. A lamp as claimed in claim 1, characterized in that the lamp base (2) is a one-piece injection molding.

3. A lamp as claimed in claim 1, characterized in that the reference element (4) is an integral part of the lamp base (2).

4. A lamp as claimed in claim 1, characterized in that the material of the lamp base (2) is molded round the reference element (4).

5. A lamp as claimed in claim 2, characterized in that the current supply means are connected to contact elements (5) by electrically conductive connections, the current supply means extending approximately parallel to the longitudinal axis of the lamp and the contact elements (5) being arranged approximately perpendicularly or parallel to the longitudinal axis of the lamp.

6. A lamp as claimed in claim 1, characterized in that the reference element (4) is arrangeable in such a way as to correspond to a reference and fixing element belonging to the light system.

7. A lamp as claimed in claim 1, characterized in that the plastics material resistant to high temperatures is PPS (Ryton, Fortron) or LCP.

8. A lamp as claimed in claim 1, characterized in that the lamp is a halogen lamp having at least one incandescent filament.

9. A method of manufacturing a lamp as claimed in claim 5, having the following steps:

placing of the lamp envelope (1), the reference element (4) and the contact elements (5) in the mold of an automatic injection molding machine,

positioning of the lamp envelope (1), the reference element (4) and the contact elements (5) relative to one another,

connecting of the current supply means of the lamp envelope (1) to the contact elements (5),

closing of the mold of the automatic injection molding machine,

feeding in of the fluidified material of the lamp base 2,

cooling and curing of the material of the lamp base 2 to form the injection molding for the lamp base 2,

opening of the mold of the automatic injection molding machine and removal of the injection molding from the mold.
