Abstract

A luminaire includes a housing with a first side wall, a second side wall opposite the first side wall and a cover wall connecting the two side walls. The luminaire further includes a lamp device with a support plate and at least one luminous element, and a holder that couples the support plate of the lamp device to the side walls such that the support plate, together with the side walls and the cover wall, define an enclosed receiving space. An electrical connection device that is electrically connected to the lamp device is arranged in the enclosed receiving space.

Claims

1. A luminaire comprising:

a housing extending in a longitudinal direction, the housing comprising a first side wall, a second side wall opposite the first side wall and a cover wall connecting the first and second side wall;

a lamp device comprising a support plate and at least one luminous element, the lamp device being arranged on a first surface of the support plate;

a holder coupling the support plate of the lamp device to the side walls such that the support plate, together with the first side wall, the second side wall and the cover wall, defines an enclosed receiving space; and

an electrical connection device electrically connected to the lamp device and arranged in the enclosed receiving space.

2. The luminaire of claim 1, further comprising:

a transparent cover, a main portion of which extends between the first and second side wall, the main portion being fastened to the first and second side wall.

3. The luminaire of claim 2, wherein the transparent cover comprises a first side portion and a second side portion, the first and second side portions each extending transversely to the main portion, the first side portion extending along the first side wall and the second side portion extending along the second side wall.

4. The luminaire of claim 3, wherein the holder is formed on the first side portion and the second side portion of the transparent cover.

5. The luminaire of claim 4, wherein the holder is formed by a first latching portion formed in the first side portion of the transparent cover and by a second latching portion formed in the second side portion of the transparent cover, an edge region of the support plate of the lamp device being held by the first and second latching portions.

6. The luminaire of claim 3, wherein the first and second side portions of the transparent cover are latched to the first and second side walls of the housing in an interlocking manner.

7. The luminaire of claim 6, wherein a first cover-latching structure is formed on an outer surface of the first side portion of the transparent cover that faces the first side wall of the housing, which first cover-latching structure engages in a first housing-latching structure formed on the first side wall, and a second cover-latching structure is formed on an outer surface of the second side portion of the transparent cover that faces the second side wall of the housing, which second cover-latching structure engages in a second housing-latching structure formed on the second side wall.

8. The luminaire of claim 3, wherein a first undercut region, which is delimited by mutually spaced hook-shaped lugs, is formed on an inner surface of the first side portion of the transparent cover that is oriented so as to face the second side portion of the transparent cover, and a second undercut region, which is delimited by mutually spaced hook-shaped lugs, is formed on an inner surface of the second side portion of the transparent cover that is oriented so as to face the first side portion of the transparent cover.

9. The luminaire of claim 1, wherein a first L-shaped projection that projects towards the second side wall is formed on the first side wall and a second L-shaped projection that projects towards the first side wall is formed on the second side wall, the first and the second L-shaped projection each overlapping with an edge region of the support plate.

10. The luminaire of claim 1, wherein the support plate comprises an aluminum material.

11. The luminaire of claim 1, wherein the electrical connection device is arranged so as to be spaced apart from the support plate of the lamp device.

12. The luminaire of claim 1, wherein the at least one luminous element comprises an LED luminous element.

13. The luminaire of claim 5, wherein the first latching portion and the second latching portion are each in the shape of a receiving groove.

14. The luminaire of claim 7, wherein the first cover-latching structure is in the shape of a latching lug, the first housing-latching structure in the shape of a latching recess, the second cover-latching structure is in the shape of a latching lug and the second housing-latching structure is in the shape of a latching recess.

15. The luminaire of claim 11, wherein the electrical connection device is fastened to the cover wall of the housing.
