Abstract

An illumination device, particularly for motor vehicles, has a housing, at least one support part, a plurality of semi-conductor light sources arranged in the support part and provided with electrical connection means for connecting the semi-conductor light sources with a voltage source. The support part has a plurality of separate support members arranged in the housing. Each of the separate support members carries only some of the semi-conductor light sources and is releasably insertable into the housing independently of other support members.

Claims

1. An illumination device particularly for motor vehicles, comprising a housing;

at least one support part;

a plurality of semi-conductor light sources arranged in said support part and provided with electrical connection means for connecting said semi-conductor light sources with a voltage source, said support part having a plurality of separate support members arranged in said housing and provided with a reflector for each of said semi-conductor light sources, said separate support members each carrying only some of said semi-conductor light sources and being releasably insertable into said housing independently of one another.

2. An illumination device as defined in claim 1, wherein said electrical connection means includes an electrical conductor for connecting said semi-conductor light sources and a plurality of connection elements for connecting said electrical conductor with a voltage source.

3. An illumination device as defined in claim 1;

and further comprising a plurality of electrical contacts arranged on said housing so that said connection means of said support members come to abutment against said electrical contacts during insertion of said support part in said housing.

4. An illumination device as defined in claim 1;

and further comprising a resistance conductor track arranged on each of said support members and operating as pre-resistance for said semi-conductor light sources.

6. An illumination device as defined in claim 4, wherein said support members are held in said housing by said connection elements which engage in said busbars.

5. An illumination device particularly for motor vehicles, comprising a housing;

at least one support part;

a plurality of semi-conductor light source arranged in said support part and provided with electrical connection means for connecting said semi-conductor light sources with a voltage source, said support part having a plurality of separate support members arranged in said housing, said separate support members each carrying only some of said semi-conductor light sources and being releasably insertable into said housing independently of one another; and

a plurality of electrical contacts arranged on said housing so that said connecting elements of said support members come to abutment against said electrical contacts during insertion of said support part in said housing, said electrical contacts are formed in said housing as busbars having a U-shaped cross-section with legs extending opposite to an insertion direction of said support part and being elastically expandable, sad connection elements extending from said support part and engaging between said legs with an elastic expansion of said legs.

7. An illumination device particularly for motor vehicles, comprising a housing;

at least one support part;

a plurality of semi-conductor light source arranged in said support part and provided with electrical connection means for connecting said semi-conductor light sources with a voltage source, said support part having a plurality of separate support members arranged in said housing, said separate support members each carrying only some of said semi-conductor light sources and being releasably insertable into said housing independently of one another; and

a plurality of light plates, each of said support members having a recess for arranging a respective one of said light plates at a side of respective one of said support members for light emitted by said semi-conductor light sources of said support member.

8. An illumination device as defined in claim 7, wherein said light disks have optical elements for influencing the light emitted by said semi-conductor light sources.

9. An illumination device particularly for motor vehicles, comprising a housing;

at least one support part;

a plurality of semi-conductor light source arranged in said support part and provided with electrical connection means for connecting said semi-conductor light sources with a voltage source, said support part having a plurality of separate support members arranged in said housing, said separate support members each carrying only some of said semi-conductor light sources and being releasably insertable into said housing independently of one another, each of said support members having an electrical conductor for said semi-conductor light sources; and

a common coating composed of a transparent synthetic plastic mass and covering both said semi-conductor light sources and said electrical conductor of each of said support members.

10. An illumination device as defined in claim 9, wherein said coating is provided with optical elements for influencing the light emitted by said semi-conductor light sources.
