## Abstract

A shelf illumination device (1) for illuminating a shelf board of a shelving system. The device (1) is mounted on a component such as the shelf board. An illumination unit (4) with a plurality of light source is attached to an illumination support (3) to illuminate at least one of the shelf boards. At least one partially transparent label holder (5) receives at least one label, a shelf marking or the like. At least one light guide (6) at least in sections extends between the illumination support (3) and the label holder (5). The light guide (6) is constructed and arranged so that a portion of light emitted by the illumination unit (4) is coupled into and propagates through the light guide (6) to at least partially backlight the label holder (5), whereas the remaining portion of the light emitted by the illumination unit (4) illuminates the shelf board.

## Claims

### Claim 1

A shelf illumination device (1) for illuminating a shelf board of a shelving system, comprising:
a device for mounting the shelf illumination device (1) on a component, in particular on a shelf board (2) of the shelving system;
an illumination support (3);
an illumination unit (4) with a plurality of light sources, wherein the illumination unit (4) is attached on the illumination support (3) so as to be able to illuminate at least one of the shelf boards of the shelving system during operation; and
an at least partially transparent label holder (5) which is adapted to receive at least one label, a shelf marking and the like,
the shelf illumination device (1) comprises at least one light guide (6) which at least in sections extends between the illumination support (3) and the label support (5) and which is constructed and arranged so that a portion of the light emitted by the illumination unit (4) can be coupled into the light guide (6) during the operation and can propagate in the light guide (6) so as to be able to at least partially backlight the label holder (5), whereas the remaining portion of the light emitted by the illumination unit (4) can illuminate the shelf board.

### Claim 2 (depends on 1)

The shelf illumination device (1) according to claim 1, wherein the label holder (5) has a first surface section (50) and a second surface section (51) that are plane-parallel, wherein a receiving area configured to receive at least a label, a shelf marking and the like is formed between the surface sections (50, 51).

### Claim 3 (depends on 2)

The shelf illumination device (1) according to claim 2, wherein the two surface sections (50, 51) are interconnected integrally by a spring section (52) that is bent in sections.

### Claim 4 (depends on 1)

The shelf illumination device (1) according to claim 1, wherein the label holder (5) is made of a transparent plastic material, in particular polyvinylchloride, polycarbonate or polymethyl methacrylate.

### Claim 5 (depends on 1)

The shelf illumination device (1) according to claim 1, wherein the device for attaching the shelf illumination device (1) on a component of the shelving system comprise a planar retaining section (54) which is constructed so that it can be brought into abutment in particular on a topside or an underside of a shelf board, and can be affixed thereon, in particular with an adhesive.

### Claim 6 (depends on 1)

The shelf illumination device (1) according to claim 1, wherein the device for mounting the shelf illumination device (1) on a component of the shelving system comprise a mounting clip (9) which is so constructed for attachment on the shelf board (2), in particular on a front face (20) of the shelf board (2).

### Claim 7 (depends on 1)

The shelf illumination device (1) according to claim 1, wherein the light guide (6) is made of transparent polymethyl methacrylate.

### Claim 8 (depends on 1)

The shelf illumination device (1) according to claim 1, wherein a surface (63) of the light guide (6) facing the illumination support (3) has a surface treatment, in particular, a white-colored layer, a reflective layer, a printed geometric pattern, a laser engraving or a V-cut engraving.

### Claim 9 (depends on 1)

The shelf illumination device (1) according to claim 1, wherein the light guide (6) has a lower section (61) which is curved in sections and which is arranged so that a free end (62) of the lower section partially extends across the light exit surfaces of the illumination device.

### Claim 10 (depends on 9)

The shelf illumination device (1) according to claim 9, wherein a lower section (33) of the illumination support (3) and a lower section (53) of the label holder (5) are curved, wherein the curvatures of the lower sections (33, 53, 61) of the illumination support (3), of the label holder (5) and of the light guide (6) are selected so that, during assembly, the lower section (33) of the illumination support (3) can be brought into abutment inside on the lower section (61) of the light guide (6) and the lower section (61) of the light guide (6) can be brought into abutment inside on the lower section (53) of the label holder (5).

### Claim 11 (depends on 1)

The shelf illumination device (1) according to claim 1, wherein the light sources are light emitting diodes (40), which are preferably arranged with a mutual spacing on a support strip (41).
