Abstract

An illumination system for indirectly or directly illuminating an outer edge arrangement of a structure covered in tiles, such as for example a step of a staircase, includes at least one elongate profile that forms a base arm, a decorative arm projecting from a free end of the base arm and the outer surface of which forms a visible decorative surface in the correctly arranged state, and a fastening arm projecting from the other free end of the base arm, arranged opposite the decorative arm, at least one illuminant that is fastened or can be fastened within the receiving space defined by the base arm, the decorative arm and the fastening arm, and at least one elongate diffusion disc cover that can be fixed to the profile.

First claim

What is claimed is:

1. An illumination system ( 1 ) for indirectly or directly illuminating an outer edge arrangement of a structure covered in tiles, such as for example a step ( 31 ) of a staircase, comprising
at least one elongate profile ( 2 ) that forms a base arm ( 6 ), a decorative arm ( 7 ) projecting from a free end of the base arm ( 6 ) and the outer surface of which forms a visible decorative surface ( 8 ) in the correctly arranged state, and a fastening arm ( 9 ) projecting from the other free end of the base arm ( 6 ), arranged opposite the decorative arm ( 7 ), wherein the fastening arm ( 9 ) is provided on its outside with at least one undercut recess ( 11 ),
at least one illuminant ( 3 ) that is fastened or can be fastened within the receiving space defined by the base arm ( 6 ), the decorative arm ( 7 ) and the fastening arm ( 9 ), and
at least one elongate diffusion disc cover ( 4 , 5 ) that can be fixed to the profile ( 2 ).

2. The illumination system ( 1 ) according to claim 1 , wherein the profile ( 2 ) is an extruded profile with a cross-section that remains the same over the entire length.

3. The illumination system ( 1 ) according to claim 1 , wherein the profile ( 2 ) is produced from aluminium or stainless steel.

4. The illumination system ( 1 ) according to claim 1 , wherein a fleece or a fabric is fastened to the outside of the fastening arm ( 9 ).

5. The illumination system ( 1 ) according to claim 1 , wherein at least one undercut recess ( 10 ) is provided on the outside of the base arm ( 6 ).

6. The illumination system ( 1 ) according to claim 1 , wherein a fleece or a fabric is fastened to the outside of the base arm ( 6 ).

7. The illumination system ( 1 ) according to claim 1 , wherein a limiting arm ( 12 ) projecting towards the decorative arm ( 7 ) is provided on the free end of the fastening arm ( 9 ).

8. The illumination system ( 1 ) according to claim 7 , wherein a holding arm ( 13 ) projecting towards the base arm ( 6 ) adjoins the limiting arm ( 12 ), said holding arm being positioned a distance away from the decorative arm ( 7 ).

9. The illumination system ( 1 ) according to claim 1 , wherein the decorative arm ( 7 ) and the fastening arm ( 9 ) extend parallel to one another and respectively at an angle of 90° in relation to the base arm ( 6 ).

10. The illumination system ( 1 ) according to claim 1 , wherein the diffusion disc cover ( 4 , 5 ) is substantially U-shaped and has a base section ( 16 ; 23 ) and two side sections ( 17 , 18 ; 24 , 25 ) projecting from the latter and lying opposite one another.

11. The illumination system ( 1 ) according claim 10 , wherein the first side section ( 17 ; 24 ) is made longer than the second side section ( 18 ; 25 ), in the correct state the illuminant ( 3 ) being positioned on the inner surface of the first side section ( 17 ; 24 ) in the region protruding with respect to the second side section ( 18 ; 25 ).

12. The illumination system ( 1 ) according to claim 11 , wherein there is formed in the region of the free end of the first side section ( 17 ; 24 ) an inwardly projecting protrusion ( 20 ; 26 ) which serves as a stop for the illuminant ( 3 ).

13. The illumination system ( 1 ) according to claim 10 , wherein the length of the side sections is chosen such that in the correctly arranged state the outer surface of the base section ( 16 ) terminates substantially flush with the free end of the decorative arm ( 7 ) of the profile ( 2 ).

14. The illumination system ( 1 ) according to claim 10 , wherein the first side section ( 24 ) has in the region of its free end a region ( 29 ) receding in the direction of the second side section ( 25 ) which is made such that in the correctly arranged state the outer surface of the protruding region ( 30 ) of the first side section ( 24 ) terminates substantially flush with the outer surface of the decorative arm ( 7 ) of the profile ( 2 ).

15. The illumination system ( 1 ) according to claim 1 , wherein, in order to fix the diffusion disc cover ( 4 , 5 ) to the profile ( 2 ) fastening means are provided which are made integrally with the profile ( 2 ) and the diffusion disc cover ( 4 , 5 ).

16. The illumination system ( 1 ) according to claim 15 , wherein the fastening means define a manually releaseable snap-on connection and are provided in particular in the form of protrusions ( 14 , 15 ) and recesses ( 21 , 22 ; 27 , 28 ) engaging with one another.

17. The illumination system ( 1 ) according to claim 1 , wherein the illuminant ( 3 ) is elongate in form, in particular in the form of a strip or a chain with a plurality of LEDs arranged over the latter.

18. An illumination system ( 1 ) for indirectly or directly illuminating an outer edge arrangement of a structure covered in tiles, such as for example a step ( 31 ) of a staircase, comprising
at least one elongate profile ( 2 ) that forms a base arm ( 6 ), a decorative arm ( 7 ) projecting from a free end of the base arm ( 6 ) and the outer surface of which forms a visible decorative surface ( 8 ) in the correctly arranged state, and a fastening arm ( 9 ) projecting from the other free end of the base arm ( 6 ), arranged opposite the decorative arm ( 7 ), wherein a fleece or a fabric is fastened to an outside of the fastening arm ( 9 ),
at least one illuminant ( 3 ) that is fastened or can be fastened within the receiving space defined by the base arm ( 6 ), the decorative arm ( 7 ) and the fastening arm ( 9 ), and
at least one elongate diffusion disc cover ( 4 , 5 ) that can be fixed to the profile ( 2 ).
