Abstract

The invention relates to a lighting device for vehicles, particularly for tractors and trailers, with a housing to which light sources of differing light generating types can be exchangeably fastened in an installed state, wherein the light sources of differing light generating types are assigned at least one optic element for the formation of a light module, which is detachably connectable to a carrier frame of the housing, and which generated a defined light function, and wherein a single lens is placed in front of the light modules of differing light generating types in the installed state and the carrier frame.

Claims

1. A lighting device for vehicles, particularly for tractors and trailers, having a housing in which replaceable light sources of differing light generating types can be fastened in an installed state, wherein the light sources of differing light generating types are assigned at least one optic element to form a light module being detachably connectable with a carrier frame of the housing and generating a defined lighting function, and wherein a single lens is placed in front of the light modules of differing light generating types in the installed state and the carrier frame.

2. The lighting device according to claim 1, wherein a light module of a first light generating type has a bulb light module with a reflector as an optic element, wherein in a vertex of the reflector, holding means for the fastening of the bulb to the reflector and contacting means for the contacting of the bulb to an electric lead connected to an electric energy source are arranged.

3. The lighting device according to claim 1, wherein a light module of a second light generating type has an LED light module with a number of light diodes as light source and an optic lens as optic element, the optic lens having a circumferential fastening edge for a mechanical connection with a printed circuit board, on which a number of light diodes is arranged, and that the printed circuit board has contacting means for the electric connection with the electric lead.

4. The lighting device according to claim 1, wherein a light module of a first light generating type and/or a second light generating type can be detachably fastened to the carrier frame, the carrier frame extending in a region between the lens and the light source or light sources of the light module of the first light generating type or the second light generating type.

5. The lighting device according to claim 1, wherein a light module of a first light generating type and/or a second light generating type is connected by snap-fastening to the carrier frame in the installed state, and that the carrier frame is shaped as a decorative bezel limiting the light aperture of the installed light module.

6. The lighting device according to claim 1, wherein the carrier frame has a number of openings, at whose edge a light module of a first light generating type or a second light generating type can be fastened respectively.

7. The lighting device according to claim 1, wherein the carrier frame has a friction-locked connection with the housing.

8. The lighting device according to claim 1, wherein a first opening of the carrier frame has a first light module of a first light generating type or a second light generating type for the formation of a direction indicator function and/or a second opening of the carrier frame has a light module of the first or second light generating type for the formation of a tail light and/or stop light function and/or a third opening of the carrier frame has a light module of the first or the second light generating type for the formation of a reversing light function and/or a fourth opening of the carrier frame has a light module of the first or the second light generating type for the formation of a rear fog light and/or license plate light function, wherein the first opening and the second opening and the third opening and the fourth opening of the carrier frame are covered by the same lens.

9. The lighting device according to claim 1, wherein light modules of a first light generating type and of a second light generating type have a coding marking the light defined lighting function.

10. The lighting device according to claim 1, wherein the transverse extension of a light module of a first or a second light generating type corresponds to a light active surface of the lens.
