Abstract

A lighting device includes a housing, at least one cover panel covering the housing and a plurality of lighting elements disposed in the housing and forming different lighting units. Four of the lighting elements are arranged in a rectangular arrangement with respect to one another so as to form a first lighting unit. The four lighting elements of the first lighting unit including two upper lighting elements disposed adjacent to one another and two lower lighting elements disposed adjacent to one another.

Claims

1. A lighting device for a rear part of a vehicle, the lighting device comprising:

a housing;

at least one cover panel covering the housing;

a plurality of lighting elements disposed in the housing and forming different lighting units, wherein four of the lighting elements are arranged in a rectangular arrangement with respect to one another so as to form a first lighting unit, the four lighting elements of the first lighting unit including two upper lighting elements disposed adjacent to one another and two lower lighting elements disposed adjacent to one another, wherein the two upper lighting elements are connected to one another by a first connecting web that extends at least from a first of the upper lighting elements to a second of the upper lighting elements and the two lower lighting elements are connected to one another by a second connecting web that extends at least from a first of the lower lighting elements to a second of the lower lighting elements, each of the first and. second connecting webs being configured to be illuminated so as to contribute to the light emitted by the first lighting unit, the two connecting webs being connected to one another in an arcuate shape; and

at least one transversely extending second lighting element having an elongated design arranged between the two upper and the two lower lighting elements.

2. The lighting device as recited in claim 1, wherein the lighting elements include light emitting diodes.

3. The lighting device as recited in claim 1, wherein the first and second connecting webs are oriented essentially horizontally or inclined with respect to the horizontal, and in each case the respective first and second lighting elements are arranged essentially horizontally at the same height or are arranged offset in relation to one another with respect to the height.

4. The lighting device as recited in claim 3, wherein one of the two upper lighting elements or two lower lighting elements are arranged horizontally essentially at the same height as one another, and the other of the two upper lighting elements or two lower lighting elements are arranged offset in relation to one another with respect to height.

5. The lighting device, as recited in claim 3, wherein the upper two lighting elements are arranged offset in relation to one another with respect to height and the lower two lighting elements are also arranged offset in relation to one another with respect to height.

6. The lighting device as recited in claim 1, wherein at least one third lighting element that has an elongated design and extends transversely is arranged between the two upper and the two lower lighting elements, said third lighting element being arranged adjacent to the second lighting element.

7. The lighting device as recited in claim 1, wherein the housing has a frame-like enclosure which is C-shaped and extends transversely, wherein one arm is arranged above and one arm is arranged below the four lighting elements of the first lighting unit.

8. The lighting device as recited in claim 7, Wherein the at least one cover panel includes a first cover panel and the frame-like enclosure projects outward with respect to the first cover panel, the first cover panel being positioned so as to cover the four lighting elements of the first lighting unit, or the frame-like enclosure is arranged essentially at the same level as the first cover panel.

9. The lighting device as recited in claim 6, wherein the at least one cover panel includes a first cover panel that is provided for covering at least one of the transversely extending linear second or third lighting elements, wherein the first cover panel projects outward with respect to a second cover panel that covers the four lighting elements of the first lighting unit or the first cover panel is arranged at the same level as the second cover panel.

10. The lighting device as recited in claim 7, wherein the flame-like enclosure is embodied in an illuminated or illuminating form.

11. The lighting device as recited in claim 1, wherein the connecting webs are narrower than the lighting elements.

12. The lighting device as recited in claim 1, wherein the connecting webs do not cover the lighting elements.

13. The lighting device as recited in claim 1, wherein the lighting elements of the first lighting unit and the connecting webs are arranged on a common arcuate printed circuit board.

14. The lighting device as recited in claim 1, wherein the first connecting web extends from the second of the upper lighting elements and the second connecting web extends from the second of the lower lighting elements into a connection section so as to provide the arcuate-shaped connection. between the two connecting webs and form a C-shaped web.
