Description

[Detailed Description of the Invention] (Industrial Application Field) This invention relates to a display shelf illumination device in which a light source is installed on a product display shelf.

(Prior art) In conventional lighting devices, fluorescent lamps are installed at predetermined intervals on the underside of the shelf, and the reflective cover scatters the light rays from the light source away from the product (towards the bottom of the shelf). It is intended to prevent
54-120972), direct irradiation was the most common.

Additionally, the fluorescent lights were attached to protrude from the bottom of the shelf.

(Problem that the invention aims to solve) Therefore, in conventional lighting devices for display shelves, the displayed products are illuminated with direct light from the light source, making it difficult to perceive the texture of the products. There was a problem that the appearance of the image deteriorated.

Further, since the fluorescent lamps are attached to protrude from the lower surface of the shelf board, the distance between the fluorescent lamps and the displayed products is very close. Therefore, there is a risk that the product will be heated by the irradiation from the light source and its quality will deteriorate, and if a sufficient space between shelves is provided to prevent this, there is a risk that the storage efficiency will decrease.

(Means for Solving the Problem) However, this invention forms a concave arc-shaped reflective surface on the lower surface of the shelf board, places the light source close to the reflective surface at a predetermined distance, and also places a light source on one side of the light source. The above-mentioned problem was solved by providing an opaque layer on the display to irradiate the displayed products almost indirectly.

The light source is preferably a slim lamp (a type of fluorescent lamp) from the viewpoint of heat dissipation, and the shelf board above the light source installation part has a heat insulating structure. Further, it is preferable that the curved surface of the reflective surface is an appropriate curved surface corresponding to the type and shape of the light source and the irradiation range of the reflected light beam.

That is, this invention forms a curved reflective surface on the lower surface of the shelf that is concave toward the upper surface of the shelf, taking into account the type and shape of the light source and the irradiation range of the reflected light beam, and forms a curved reflective surface that is concave toward the upper surface of the shelf and maintains a predetermined distance from the reflective surface. In this display shelf lighting device, a light source is installed with the light source maintained, an opaque layer is provided on the tip side of the shelf board of the light source, and the shelf board is interposed with a heat insulating material at least in a portion above the light source installation position.

(Function) According to the display shelf illumination device according to this invention, the light source is installed by entering the recessed part of the shelf board, so that the distance between the light source and the displayed products is larger than before.

Furthermore, since an opaque layer is formed on one side of the light source, direct irradiation of light onto the displayed products is restricted, and the eyes of the purchaser can be blinded.

(Example) Next, an example of this invention will be described.

The display shelf 1 shown in FIG.
is fixed vertically, and shelf boards 2, 3, 4 are attached to this frame 12.
are arranged horizontally in parallel at predetermined intervals. Display shelf lighting devices 5 are attached to appropriate positions on the lower surface of each of the shelf boards (see FIG. 2).

That is, this lighting device 5 has a concave arc-shaped reflective surface 6a.
It is composed of a steel reflector 6 having a reflector 6, and a slim lamp 7 with an opaque layer supported by brackets 9 at both ends of the reflector 6. The specific configuration of this lighting device 5 will be explained based on FIG. 2.

FIG. 2 is a partially enlarged sectional view of the shelf board 3, in which a heat insulator 10 having a concave arc-shaped reflective surface 6a is fitted and fixed on the lower surface near the tip. The reflective plate 6
A slim lamp 7 is attached at a predetermined distance from the concave arc-shaped reflective surface 6a. The radius of curvature of the curved shape of the reflective surface can be freely set depending on the irradiation range of the reflected light beam.

Lower part of the slim lamp 7 (tip side of shelf board)
A band-shaped light-shielding film for blocking direct light is adhered to the film, and an opaque layer 8 is formed by the film. The opaque layer 8 also has the function of shielding the eyes of buyers of displayed products.

With the above configuration, in the display shelf illumination device 5 attached to the shelf board 3, the slim lamp 7 is halfway into the concave arc-shaped part of the concave arc-shaped reflective surface 6a, so that the interval between adjacent shelf boards can be changed. Therefore, the distance between the slim lamp 7 and the displayed products can be made larger than before.

In addition, an opaque layer 8 provided on the slim lamp 7
This will almost completely prevent direct irradiation of displayed products.

(Effects of the invention) According to this invention, since the lighting device for display shelves has the above-mentioned configuration, the distance between the light source and the displayed products can be secured without changing the distance between adjacent shelf boards, so that the products themselves can be It does not get very hot, and there is no risk of it being affected by light sources.

In addition, the opaque layer restricts direct light from the light source, and most of the irradiation to the displayed products is indirect irradiation from the reflective surface, which improves the texture and appearance of the displayed products. play.

In addition, since the curved surface is formed taking into account the type and shape of the light source and the illumination range of the reflected light beam, the product can be evenly illuminated. Furthermore, since the shelf board corresponding to the light source has a heat insulating structure, there is no risk that the heat from the light source will have an adverse effect on the product.
