Description

  The present invention relates to an illuminating device used for a merchandise display shelf or the like, and in particular, a pair of left and right brackets supports the lower surface of the shelf plate, and an illuminating device is provided below the shelf plate. The present invention relates to an illumination device for a display shelf that illuminates products on a shelf board.

  There are various types of lighting devices attached to fixtures and the like. For example, product display shelves are constructed by attaching shelves in multiple stages, and the products displayed on the lower shelves are illuminated to display product effects. A lighting device is attached to the lower surface of the shelf board.

  Conventionally, a fluorescent lamp is generally used as a light source for this illumination. In a lighting device for a shelf board using a fluorescent lamp, a fluorescent lamp is attached along the front width direction to the lower front part of the shelf board, and power is supplied through sockets attached to both ends. The product is lit.

  Illumination light sources such as the above-described fluorescent lamps and other lighting devices such as incandescent bulbs and spotlights generate a large amount of heat and consume much power. Under these circumstances, in recent years, light emitting diodes (LEDs) that generate less heat and consume less attention, and the number of lighting devices that include light emitting diodes (LEDs) is increasing.

  Patent Document 1 discloses an example of a display shelf lighting device in which a lighting device using light emitting diodes (LEDs) is attached to a pair of left and right brackets.

  FIG. 20 shows a lighting device for a display shelf to which a lighting device using light emitting diodes (LEDs) is attached to a pair of conventional left and right brackets.

  As shown in FIG. 20, locking portions 241 and 241 for locking to a pair of left and right brackets 217 and 217 are provided at the left and right ends of the lighting device 244 at the side end portions that form the left and right ends of the lighting device 244. Screws 248 are screwed into the mounting holes formed. The lighting device 244 has a plurality of light emitting diodes (LEDs) arranged in the left-right direction (not shown), and is supplied with power from the power cable 249 to the light emitting diodes (LEDs).

  Engagement grooves 217b and 217b are formed in the upper end edge 217a of the brackets 217 and 217 as recesses to which the locking members 241 and 241 can be freely fitted. The lighting device 244 is attached to the brackets 217 and 217 by being locked to 217b.

  In this manner, the lighting device 244 can be easily attached simply by locking the locking members 241 and 241 of the lighting member 244 using the left and right brackets 217 and 217 that support the shelf board.
