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 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.

2. :

The lighting device as recited in claim 1, wherein in each case two of the lighting elements are connected to one another by a connecting web.

3. :

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

4. :

The lighting device as recited in claim 2, wherein the connecting webs are oriented essentially horizontally or inclined with respect to the horizontal, and in each case a connecting web connects to one another two lighting elements which are arranged essentially horizontally at the same height or two lighting elements which are arranged offset in relation to one another with respect to the height.

5. :

The lighting device as recited in claim 4, wherein a first connecting web connects two lighting elements which are arranged horizontally essentially at the same height as one another, and a second connecting web connects two lighting elements which are arranged offset in relation to one another with respect to height.

6. :

The lighting device as recited in claim 4, wherein in each case a connecting web connects two lighting elements which are arranged offset in relation to one another with respect to height.

7. :

The lighting device as recited in claim 2, wherein the two connecting webs are connected to one another in an arcuate shape.

8. :

The lighting device as recited in claim 2, wherein the connecting webs are embodied in an illuminated or illuminating or unilluminated form.

9. :

The lighting device as recited in claim 1, wherein at least one transversely extending linear second lighting element is arranged between the two upper and the two lower lighting elements.

10. :

The lighting device as recited in claim 9, wherein at least one transversely extending linear third lighting element is arranged between the two upper and the two lower lighting elements, said lighting element being arranged adjacent to the second lighting element.

11. :

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

12. :

The lighting device as recited in claim 11, wherein the frame-like enclosure projects with respect to a cover panel for covering the four lighting elements which are arranged in a rectangular arrangement with respect to one another or is arranged essentially at the same level.

13. :

The lighting device as recited in claim 1, wherein a first cover panel is provided for covering at least one of the transversely extending linear second or third lighting elements, wherein this cover panel projects with respect to a second cover panel that covers the four lighting elements of the first lighting unit or is arranged at the same level.

14. :

The lighting device as recited in claim 11, wherein the frame-like enclosure is embodied in an illuminated or illuminating form.
