Description

  The present invention relates to an LED lighting device that is mounted on a shelf on which products are displayed and illuminates a display of products and advertisements, and a product display shelf that is mounted with the lighting device.

In order to clearly show the products placed on the display shelves to the customers, various methods of lighting have been conventionally performed.
For example, a method of illuminating a product placed on a display shelf having several levels by providing a lighting device in front of the upper portion, or arranging a lighting device in the upper portion of each step is employed.
In addition, there is a type in which the shelf plate is made of a transparent material such as glass or plastic, and light illuminated from above is passed through the transparent material shelf to irradiate the lower shelf. The light of the luminaire installed on the top of the shelf can pass through the upper transparent shelf to illuminate the upper shelf.

An illumination light source such as an LED element is provided on each surface of the V-shaped mounting plate, and this is arranged on one shelf to irradiate light upward and downward, and the light emitted upward is the upper side. An illumination system that illuminates a product placed on a lower shelf plate by illuminating the display board and emitting light emitted downward is conceivable.
FIG. 10 is a diagram showing an outline of the lighting system, in which (a) is a front view of a display shelf incorporating the lighting system, (b) is a side view of the display shelf, and (c) is an LED constituting the lighting system. Each element mounting substrate is shown.
The display shelf board 42b is a horizontally long transparent plastic board, and a number of products (such as cosmetics) 43 are displayed on the display shelf board 42b. A display shelf plate 42a is disposed above the display shelf plate 42b, and a horizontally long board mounting plate 44 having a V-shaped cross section is disposed on the display shelf plate 42a. An illumination substrate 46 in which a large number of LED elements 45 are arranged is mounted on the plate surfaces 44 a and 44 b of the substrate mounting plate 44.

A display display board 41 in which characters, pictures, etc. are attached to a transparent plastic board is positioned in front of the display shelf board 42a so that it can be easily viewed by customers.
The light emitted from the illumination substrate 46 mounted on the plate surface 44a illuminates and displays characters and pictures on the display display board 41.
On the other hand, the light emitted from the illumination board 46 mounted on the plate surface 44b can pass through the display shelf 42a and illuminate the product 43 displayed on the display shelf 42b.

Moreover, as a lighting device for illuminating a display stand, a display shelf lighting device that can be easily attached to the front edge of a shelf board and has excellent eye-catching properties has been proposed (Patent Document 1).
This display shelf lighting device is provided with a lighting device that illuminates and emits a plurality of LEDs mounted on a substrate in a thin plate-like case at the front edge portion of the display shelf. Illumination is performed from the back of the card inserted into the card holder.
However, the LED mounted on the substrate is for illuminating a card indicating the manufacturer brand of the product and not for illuminating the product displayed on the display shelf.

As an illuminating device for illuminating a product, a shelf lamp that can uniformly illuminate the entire product display space below the shelf plate of the product display shelf has been proposed (Patent Document 2).
This shelf down lamp is provided on the lower surface of the front end of the shelf plate, and illuminates the entire shelf plate by providing a light distribution control means for distributing a part of the LED light to the back side of the shelf.
The shelf light is used to illuminate the product with illumination only in the lower surface direction. For example, the shelf light is not configured to illuminate the other direction and illuminate a display board for displaying advertisements, product names, and the like.

There has been proposed a lighting fixture that illuminates both a display part (shade) and a product under the shelf (Patent Document 3).
In this lighting fixture and product display shelf, the LED illuminator attached to the mounting portion of the shelf plate has a large number of LED elements mounted on one surface of the board, and the light from the many LED elements is downward in a certain irradiation angle range. , And a part of the light is reflected by the reflector, and the sign sheet in the shade is irradiated from the back side.

However, a configuration is adopted in which irradiation light is irradiated in one direction within a certain irradiation angle range, and the light is divided into two to guide light in the vertical direction.
Since this structure employs a configuration using a reflecting plate, the structure of the display shelf becomes complicated, which also causes an increase in price. Moreover, since it is set as the structure which divided light into 2, it is not certain whether it is what fully illuminates the goods under a shelf uniformly. In addition, since the light that illuminates the sign sheet is guided once reflected, the angle of the light that illuminates the sign sheet is not from the right angle direction, but the light hits the structure where the light enters obliquely, The distribution of light that illuminates is also not appropriate.
