Abstract

The invention provides a wall or ceiling covering arrangement (10) comprising a covering material (100) and a lighting system (200) arranged to generate light (210). The covering material (100) has a user side (101) and an opposite back side (102). The lighting system (200) is arranged at the back side (102) of the covering material (100) and the covering material (100) has a light transmission for light (210) generated by the lighting system (200) in the range of 0.5% to 30%, especially in the range of 1% to 20%. The covering material comprises a material selected from the group consisting of plasters and wallpapers.

Claims

1. A wall or ceiling covering arrangement (10) comprising:

a covering material (100) having a user side (101) and an opposite back side (102), and

a lighting system (200) provided at the back side (102) of the covering material (100), and arranged to generate light (210),

wherein the covering material (100) has a light transmission for light (210) generated by the lighting system (200) in the range of 0.5% to 30%, and

wherein the covering material comprises a material selected from the group consisting of plasters and wallpapers.

2. The wall or ceiling covering arrangement (10) according to claim 1, wherein the covering material comprises a plaster comprising stone granules and a binder.

3. The wall or ceiling covering arrangement (10) according to claim 1, wherein the covering material comprises a wallpaper selected from the group consisting of vinyl wallpaper and glass fiber wallpaper.

4. The wall or ceiling covering arrangement (10) according to claim 1, further comprising an auxiliary layer (500), arranged between at least part of the lighting system (200) and at least part of the covering material (100), wherein the auxiliary layer (500) comprises one or more of an adhesive layer, a levelling layer, a scratch resistance layer, and a liquid-tight layer.

5. The wall or ceiling covering arrangement (10) according to claim 1, wherein the lighting system (200) comprises a plurality of lighting units (250), and wherein the wall or ceiling covering arrangement further comprises a controller (300) arranged to control the lighting system (200).

6. lighting system (200) for use in the wall or ceiling covering arrangement (10) according to claim 1, comprising

one or more light sources (205), and

a printed circuit board with one or more recesses (204) arranged to host the one or more light sources (205).

7. A lighting system (200) for use in the wall or ceiling covering arrangement (10) according to claim 1, comprising a top side (201) for facing the covering material and a back side for facing the wall or ceiling, the top side (201) having adhesion promoting properties.

8. A lighting system (900) for use in the wall or ceiling covering arrangement (10) according to claim 1, comprising a wedge-shaped edge (910) having a first face for being adjacent to the wall or ceiling (940), and a second face for being adjacent to the covering material (930), the first face and the second face enclosing an angle φ

that is smaller than 6 degrees.

9. A lighting system (200) for use in the wall or ceiling covering arrangement (10) according to claim 1, comprising one or more light sources (205) provided on a printed circuit board, the lighting system (200) having a top side for facing the covering material, and a back side for facing the wall or ceiling, wherein at the top side the lighting system (200) comprises one or more auxiliary layers (500) chosen from the group consisting of adhesive layers, levelling layers, and protective layers.

10. The lighting system (200) according to claim 9, wherein the one or more auxiliary layers (500) comprise a liquid-tight protective layer, and wherein the lighting system (200) further comprises a liquid-transporting layer at the side of the liquid-tight protective layer facing away from the printed circuit board.
