Abstract

A light device for vehicles has a housing mountable on a vehicle part and a light adjustably received in the housing. The housing is provided with a region which is curved in an adjustment direction of the light and the light abuts against the region. At least one mounting element extends through the housing and fixes the light so that when the mounting element is released, the light is displaceable inside the housing along the curved region, and a control element is arranged outside of the housing and follows an adjusting movement of the light. The control element is provided with indicating means for indicating an orientation of an optical axis of the light.

Claims

1. A light device for vehicles, comprising a housing mountable on a vehicle part, said housing being provided with a region which is curved;

a light received in said housing and abutting against said region;

at least one mounting element extending through said housing and fixing said light to said housing so that when said mounting element is released, said light is displaceable inside said housing along said curved region; and

a control element arranged outside of said housing and coupled with said light for following an adjusting movement of said light, said control element being provided with indicating means for indicating an orientation of an optical axis of said light, said at least one mounting element being fixedly connected with said light in an adjusting direction, extending through said control element and entraining said control element during an adjustment of said light.

2. A light device as defined in claim 1, wherein said housing has a longitudinally extending opening, said mounting element extending through said opening of said housing.

3. A light device as defined in claim 1, wherein said plan surface is located vertically with respect to a roadway with a correct orientation of said optical axis of said light.

4. A light device as defined in claim 1, wherein said control element is formed as a water level which is arranged on said light and has a light bubble with a scale forming together said indicating means.

5. A light device as defined in claim 1;

and further comprising means for mounting said housing on a window pane of the vehicle.

15. A light device as defined in claim 1, wherein said control element is formed as a water level which is arranged on said mounting element and has a light bubble with a scale forming together said indicating means.

6. A light device for vehicles, comprising a housing mountable on a vehicle part, said housing being provided with a region which is curved;

a light received in said housing and abutting against said curved region;

at least one mounting element extending through said housing and fixing said light to said housing so that when said mounting element is released, said light is displaceable inside said housing along said curved region;

a control element arranged outside of said housing and coupled with said light for following an adjusting movement of said light, said control element being provided with indicating means for indicating an orientation of an optical axis of said light, said light having a plurality of semi-conductor light sources;

a light housing; and

a plurality of support parts each provided with a portion of all said semi-conductor light sources of said light and insertable in said light housing independently of one another.

7. A light device as defined in claim 6;

and further comprising electrical contact elements arranged in said light housing and connection elements provided on said support parts and abutting against said contact elements during insertion of said support parts in said light housing.

8. A light device as defined in claim 7, wherein said electrical contact elements are formed as busbars which are U-shaped in longitudinal sections through said light housing, said busbars having legs which extend against an insertion direction of said support part and are elastically expandable, said connection elements extending outwardly beyond said support parts and between said legs with elastic expansion of said legs.

9. A light device as defined in claim 8, wherein said connection elements are inserted in said busbars, said support parts being held in said light housing by said connection elements inserted in said busbar.

10. A light device as defined in claim 6, wherein each of said support parts has a receptacle;

and further comprising transparent light plates each received in said receptacle and located forwardly of said semi-conductor light sources.

11. A light device as defined in claim 10, wherein said light plate is provided with optical elements for influencing the light radiated by said semi-conductor light sources.

12. A light device as defined in claim 6;

and further comprising an electrical conductor provided for said semi-conductor light sources, said semi-conductor light sources and said electrical conductor of each of said support parts being surrounded by an injection molded joint coating of a transparent synthetic plastic material.

13. A light device as defined in claim 12, wherein said coating is provided with optical elements for influencing a light radiated by said semi-conductor light sources.

14. A light device as defined in claim 6;

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