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 transparent cover including

a main portion that extends between the first side wall and the second side wall and that is fastened to the first side wall and the second side wall,

a first side portion extending transversely to the main portion of the cover and along the first side wall,

a second side portion extending transversely to the main portion of the cover and along the second side wall,

a holder formed by a first latching portion formed in the first side portion and by a second latching portion formed in the second side portion, a first edge region of the support plate being held by the first latching portion and a second edge region being held by the second latching portion, whereby the support plate of the lamp device is coupled 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;

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

2. The luminaire of claim 1, wherein the first latching portion is formed by a first receiving groove extending in the first side portion of the transparent cover and the second latching portion is formed by a second receiving groove extending in the second side portion of the transparent cover, the first edge region of the support plate being received in the first receiving groove and the second edge portion of the support plate being received in the second receiving groove.

3. The luminaire of claim 2, wherein the first latching portion and the second latching portion are each in the shape of a receiving groove.

4. The luminaire of claim 1, 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.

5. The luminaire of claim 4, 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.

6. The luminaire of claim 5, wherein the first cover-latching structure is in the shape of a latching lug, the first housing-latching structure in 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.

7. The luminaire of claim 1, 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.

8. 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.

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

10. 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.

11. The luminaire of claim 10, wherein the electrical connection device is fastened to the cover wall of the housing.

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

13. The luminaire of claim 1, wherein the holder is formed in an end region of each of the first side portion and the second side portion, and wherein the end region that is remote from the main portion of the cover.
