Abstract

PURPOSE:To obtain lighting devices whereby commodities are equally lightened by arranging surface-illuminants on the undersurface of each of selves and on the top surface in the present showcase. CONSTITUTION:Each of lighting devices 10 is composed of both surface- illuminants 12 which are stuck in the shape of pavement on the undersurface of a shelf board 82 and terminals 13a on the side of an electric source which are provided on a bracket 81 and connected to the electric source through lead wires 13 and are also connected to terminals 12a. These lighting devices 10 are provided on the undersurface of each of shelves 8 and on the top surface in a showcase 4. When electricity is turned on, each of the lighting devices 10 emits light from all the surfaces of the surface-illuminants 12 and lightens commodities on the shelf 8 at the downward part thereof. In this way, all of the commodities on the shelves are equally lightened and made easy to look, and are also cooled equally.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides a showcase that includes a main case with a U-shaped cross section and an opening for taking out products on the front surface, and in which products are displayed and stored inside the main case. The present invention relates to a lighting device for illuminating the product.

[Conventional technology]

As a showcase, a cold air circulation type multi-stage open showcase shown in FIG. 5 is known. This open showcase includes a main body case 1 having a U-shaped cross section and having an opening 1a for taking out products on the front side. The main case 1 is composed of an outer box 2 and an inner box 3 made of heat insulating walls, and a refrigerator interior 4 is formed inside the inner box 3, and a cold air circulation path 5 is provided between the outer box 2 and the inner box 3. is formed, and a fan 6 and a cooler 7 are arranged here. Inside the warehouse 4, a plurality of shelves 8 are provided above and below so that products can be effectively displayed and stored. This shelf 8 is constructed by placing and locking a shelf board 82 on a pair of left and right brackets 81 whose rear ends are removably held by shelf pillars that stand upright along the back plate of the inner box 3. At the front end of the shelf 8 and the front end of the ceiling surface inside the refrigerator, straight tube fluorescent lamps 11 are installed, respectively, as a lighting device for illuminating the products below.

The oven showcase uses a fan 6 to draw air inside the refrigerator from a suction port 5a into a cold air circulation path 5, passes through a cooler 7, converts it into cold air, and blows it out from a blowout port 5b. The cold air forms a cold air curtain 9 in the opening 1a and cools the inside 4 of the refrigerator. Thus, the products displayed and stored on the bottom plate and shelf board 82 of the refrigerator are refrigerated and illuminated by the fluorescent lamp 11.

FIG. 6 shows a showcase with a front door, so-called a reach-in showcase, as another conventional example. This reach-in showcase is provided with a door 15 for opening and closing the opening 1a on the front surface of the main body case l of the open showcase, and shelf boards 82 on the rear and front left and right shelves that are locked to the shelf pillars. Straight tube fluorescent lamps 11 are supported by the receiver 83 and are provided on both left and right sides of the front end of the chamber in the vertical axis direction for illuminating the products. However, similar to an open showcase, products are displayed and stored on shelves 8 and refrigerated, and fluorescent lights 1
1.

[Problem to be solved by the invention]

By the way, in conventional showcases, whether in the open showcase or the reach-in showcase, the illumination of the products is uneven depending on whether they are close to or far from the fluorescent lights 11, and for example, products that are far from the fluorescent lights 11 have a problem in that it is difficult for customers to see them. was there.

In addition, there is a concern that products near the fluorescent lamp 11 may not be cooled uniformly because they receive a lot of heat from the lighting.

An object of the present invention is to provide a lighting device that uniformly illuminates products in a showcase.

[Means to solve the problem]

In order to achieve the above object, the present invention is provided with a main case having a U-shaped cross section with an opening on the front, and inside the main case, products are displayed and stored in multiple upper and lower stages partitioned by shelves. In a lighting device that is installed in a showcase that forms a refrigerator interior and illuminates the products, a surface light emitting body is installed on the lower surface of the groove and on the ceiling surface of the refrigerator interior.

(Function) Since conventional fluorescent lamps are linear light sources, it was difficult to display products at a uniform distance from the light source, but by using a surface light source, the displayed products can be displayed at approximately the same distance from the light source, making it uniform. Therefore, the amount of heat received by the illumination is approximately the same, resulting in uniform cooling.

〔Example〕

1 to 4 show embodiments of this invention,
Components common or identical to those in FIGS. 5 and 6 are designated by the same reference numerals.

In FIGS. 1 to 4, reference numeral 12 is a tile-shaped surface light emitting body commercially available under the name of "Shining Tile" by Nissho Giken Co., Ltd., for example. This surface light emitter has terminals 12a connected to internal electrodes on both sides, and when energized, it emits light uniformly from the entire surface. Further, the terminals can be connected and installed in a row, and the back side can be glued to the installation location.

The surface light emitters 12 are attached to the lower surface of a shelf board 82 so as to be arranged side by side, and the bracket 81 is connected to a power source through a lead wire 13 and is provided with a terminal 13a on the power source side that is connected to the terminal 12a. 10 are configured. This lighting device 10 is provided on the lower surface of each column 8 and on the ceiling surface of the refrigerator interior 4. In addition, reach-in showcase ll1
A holder (not shown) is provided in place of the bracket 81 for attaching the terminal 13a to the II8 and the lighting device 10 provided on the ceiling surface.

In the above-described configuration, when electricity is applied, the lighting device 10 emits light from the entire surface of the surface light emitter 12 to illuminate the products on the shelf 8 below. Therefore, the products are uniformly illuminated no matter where they are on the shelf board 82, and some products will not become difficult to see for customers looking from the front. Also, it is prevented that some products are difficult to cool down due to strong lighting, and the entire product is cooled uniformly.

〔Effect of the invention〕

According to the present invention, the main body case is provided with a U-shaped cross section and has an opening on the front, and inside the main body case there is provided a showcase that is partitioned into upper and lower stages by shelves and forms an interior in which products are displayed and stored. In the lighting device for illuminating the products, surface light emitters are installed on the bottom surface of the groove and on the ceiling surface of the warehouse interior to constitute the lighting device, so that all the products on the shelf are displayed at the same time. The entire product can be easily seen by customers. In addition, it is possible to prevent some products from being sufficiently cooled due to strong illumination, and all products are cooled uniformly.
