Description

  The present invention relates to a lighting device using LEDs used for a shelf for displaying and selling cosmetics and the like, and a merchandise display shelf including the lighting device.

Patent Document 1 discloses a lighting device for a merchandise display shelf that displays and sells cosmetics at a drug store or the like. The one with the light case attached is described. The translucent case is opened rearward, and a sign sheet (display board) on which the name, price, etc. of the product are written is attached to the front surface. A fluorescent lamp is used as the illuminating body, and the product displayed on the sign sheet or the lower shelf is illuminated with the light of the fluorescent lamp.
The conventional lighting device uses a fluorescent lamp as an illuminating body. The fluorescent lamp has a relatively short life and needs to be frequently replaced. Further, since the power consumption is large, the running cost is high. Furthermore, there is a disadvantage that the product is heated by the heat and ultraviolet rays emitted from the fluorescent lamp or the product package is burnt.

In recent years, the performance of LEDs such as brightness has been greatly improved, and LEDs have many advantages such as longer life and lower power consumption than fluorescent lamps, so LEDs are often used instead of fluorescent lamps. In addition, under-shelf lighting using LEDs has already been put into practical use by the present applicant (see Non-Patent Document 1). However, since the LED emits light only in one direction, it is difficult to brightly illuminate both the front sign sheet and the product under the shelf even if the LED is incorporated in the conventional lighting device instead of the fluorescent lamp.
Moreover, since the said conventional illuminating device needs to attach a lighting body and a translucent case separately to a shelf board, it took the effort for construction.
