Description

  The present invention relates to a lighting device in which a light emitting element such as a light emitting diode as a lighting fixture is attached to a shelf provided in a showcase, a product display shelf, a cabinet, furniture, or the like.

In conventional shelf lighting of merchandise display shelves, fluorescent lamps are placed on the front of the shelf and the lower side is illuminated, so that direct light from the lighting is not applied to people on the front of the shelf. A shielding plate about the diameter of the fluorescent tube was required.
For this reason, the rear side of the lower surface of the shelf arranged in the upper stage is not visible from the front due to the shielding plate, and a large blind spot is generated.
In view of this, Japanese Patent Application Laid-Open No. 2001-250420 discloses a shelf illuminating device in which a light emitting element is built in a shelf board instead of a fluorescent lamp, a display is held on the upper surface, and the lower part is irradiated with the light emitting element.
According to this structure, although the lower part of a shelf board can be illuminated, there exists a fault that illumination does not reach even the front upper surface of a shelf board.
On the other hand, in Japanese Patent Laid-Open No. 2001-112655, a structure is known in which a light emitting element built in a shelf plate of a storage cabinet is reflected and scattered by using a reflector to irradiate light up and down. You can illuminate the top and bottom of the front, but the light will be weak and you will not be able to illuminate the displayed product brightly.
