Description

The present invention relates to a display shelf lighting system using a solar cell as a lighting power source for a display shelf.

Conventionally, in this kind of display shelf for displaying products on a shelf, a plurality of shelves are installed, a light source such as a fluorescent lamp is provided at the front of the bottom surface of the shelf, and the products on the shelf located below the shelf are arranged. Illuminated.

In such a conventional display shelf, power is supplied to the light source by a commercial power source. Therefore, the outlets provided on the wall surface or the floor surface from the display shelf are connected by electric wires, and a predetermined electric power is supplied. Wiring processing was required.

Therefore, if electrical outlets are installed near the display shelf location, electrical wiring processing can be performed relatively smoothly. However, electrical outlets are not always nearby, and are associated with relocation in the store. When the display shelf is moved, there are inconveniences such as electric wiring processing is difficult to adapt to the occasion.

On the other hand, it is conceivable to use a solar cell as the power source of the light source in order to eliminate the need for electrical wiring processing. For example, in a showcase, a solar cell is provided corresponding to each fluorescent lamp provided on the lower surface of a shelf, and a part of light from the fluorescent lamp is converted into electric power by this solar cell (“Patent Document 1”). reference).

  However, what is shown in “Patent Document 1” is to supply power to a load mainly by a storage battery charged by a commercial power source, and the electric power generated by the solar battery is used only for assisting the storage battery charging.

Therefore, since a commercial power source is used, electrical wiring processing is necessary, and it is based on the premise that the power supplied to the load is not sufficient with the power of the solar cell.

The present invention uses a solar cell as a power source of a shelf light source for illuminating a shelf, eliminates the need for electrical wiring processing between outlets provided on the wall surface or floor surface from the display shelf, and improves the degree of freedom of arrangement of the display shelf. Another object of the present invention is to provide a display shelf lighting system that can achieve a desired lighting effect on the shelf.

The display shelf lighting system according to claim 1 is provided in a display shelf main body having a shelf, a shelf light source that illuminates the shelf, an upper opening portion of the display shelf main body, and power to the shelf light source. A solar cell to be supplied and a light source that is installed indoors and that emits light toward a light receiving portion of the solar cell are provided.

In the present invention, terms and technical meanings are as follows unless otherwise specified.

The “open upper part of the display shelf main body” is an upper part of the display shelf main body that is less likely to be obstructed by light from the light source directed to the light receiving part of the interior lighting or solar cell. It is what you point to.

Installing the light source in the room includes attaching the light source to a ceiling surface or a wall surface and arranging the light source in the room by a stand or the like.

The light source for irradiating light toward the light receiving part of the solar cell may be a light source for indoor illumination or illumination such as merchandise, or may be provided specifically for the purpose of solar cell irradiation.

  According to the first aspect of the present invention, since the solar cell is used to supply power to the shelf light source, it is possible to save energy, eliminate the need for electrical wiring processing, and improve the degree of freedom in arranging the display shelf.

Moreover, since the solar cell is provided in the upper open part of the display shelf body, it is not only easy to receive the light of the indoor lighting, but also receives the light from the light source directed to the light receiving part of the solar cell and effectively generates power. The effect can be achieved to achieve the desired lighting effect on the shelf.

In addition, since the light source is directed to the upper open portion of the display shelf main body, the display shelf illumination system capable of performing the function of illuminating the display shelf and the function of room lighting is provided from the spread of the light irradiation. be able to.

A display shelf lighting system according to a first embodiment of the present invention will be described with reference to FIGS. FIG. 1 is a perspective view showing a commodity display shelf body, and FIG. 2 is a side view thereof.

The display shelf main body 1 includes a base 2 and a back wall 3 that rises substantially vertically from the base 2. Casters 4 that contribute to the movement of the main body are attached to the four positions on the lower surface of the base. A plurality of display shelves 5a, 5b, 5c, and 5d are provided on the back wall 3 so as to extend forward. The display shelves 5a, 5b, 5c, and 5d are arranged with the front and rear widths of the shelves 5a and 5b positioned on the upper side downward so that customers can easily see the products placed on the display shelves 5a, 5b, 5c, and 5d. It is configured to be narrower than the shelves 5c and 5d.

The upper surface of the base 2 functions as a display shelf, that is, the lowermost display shelf 5e among the plurality of stages of display shelves 5a, 5b, 5c, 5d, and 5e.

Next, shelf light sources 6a, 6b, 6c, and 6d that illuminate the respective lower display shelves 5b, 5c, 5d, and 5e along the longitudinal direction are provided on the front lower surfaces of the display shelves 5a, 5b, 5c, and 5d. ing. Accordingly, the display shelves 5b, 5c, 5d, and 5e are illuminated by the shelf light sources 6a, 6b, 6c, and 6d, and the uppermost shelf 5a is illuminated by room lighting.

Moreover, the solar cell 8 is attached to the back wall upper end part 7 as an upper open part of the display shelf main body 1 with the light receiving part 8a in a panel shape, and the solar cell 8 uses the generated power to each light source 6a. , 6b, 6c, 6d are electrically connected in parallel to the light sources 6a, 6b, 6c, 6d. Considering the power generation capability of the solar cell 8, the shelf light sources 6a, 6b, 6c, and 6d are preferably LEDs, cold cathode lamps, organic ELs, and the like that consume relatively little power.

By the way, the power generation capacity of the solar cell 8 that supplies power to the light sources 6a, 6b, 6c, and 6d tends to be insufficient only from the light of the in-store lighting. Therefore, as shown in FIG. 3, a light source, for example, a spotlight 10 capable of adjusting the irradiation angle is attached to the ceiling surface 11, and the light is irradiated toward the light receiving portion 8 a of the solar cell 8.
