Description

  The present invention relates to a lighting device for a product display shelf and a display shelf, and more particularly, to an improved technique for improving the product display effect and product rendering performance while realizing space saving without requiring a decorative illumination and a power source. .

  In a display shelf configured by attaching shelves in multiple stages, an illuminating device for illuminating the displayed products on the lower shelf board to enhance the product display effect may be attached to the lower front part of the shelf board. Conventionally, a fluorescent lamp has been generally used as the light source of the illumination device. In a shelf illuminator using fluorescent lamps, fluorescent lamps are attached to the front of the bottom of the shelf along the front width direction, and power is supplied through sockets attached to both ends to illuminate display products on the lower shelf. did.

  However, illumination light sources such as fluorescent lamps, incandescent bulbs, and spotlights contain an ultraviolet component that induces deterioration of the irradiated object in the illumination light, and the amount of heat generated by light sources such as incandescent bulbs is large. Under such circumstances, in recent years, light emitting elements (LEDs) that generate less heat, ultraviolet components, and power consumption have attracted attention, and in combination with the provision of high-intensity white LEDs, LEDs are used in lighting devices. Things to do are increasing. An example of this type of lighting device is disclosed in Patent Documents 1 and 2, for example.

On the other hand, a display shelf or a sample (sample) may be provided on the display shelf separately from the product. When a sales promotion display uses a lighting device, a light source such as a decorative fluorescent light, an incandescent light bulb, or a spotlight is required separately from the lighting device for the above-described product, and power supply is also performed separately. It was.
