Description

  The present invention relates to a lighting fixture which is installed under a shelf such as a showcase or a display shelf and mainly illuminates a product displayed in a lower stage, and particularly relates to a lighting fixture under the shelf using an LED as a light source. .

  Under-shelf lighting fixtures were mainly made of thin fluorescent tubes, but the adverse effects on display products due to ultraviolet rays and heat generated by fluorescent tubes, and environmental pollution problems associated with disposal of fluorescent tubes using mercury As a result, alternative lighting fixtures using LEDs as light sources have attracted attention.

  It is an object of the present invention to provide a lighting fixture that can be easily installed under a shelf lighting fixture that uses LEDs as a light source and that efficiently illuminates products displayed in the lower stage.

  A plate nut 7 for forming a mounting surface 9 of a tape-shaped LED substrate 3 in which a plurality of LEDs are linearly arranged in a U-shape and screwing a support member to an arbitrary position on the back surface in the longitudinal direction. An aluminum shape member provided with a pair of fitting grooves 8 for mounting a flat, substantially U-shaped transparent resin cover 4 that covers the entire width of the mounting surface 9 of the substrate 3 is provided. 2, and an end cap 5 provided with a square notch 10 abutting against the end of the instrument body 2 is attached, and the square notch 10 is connected to the insertion hole of the power cord or the connector 11 of the power cord. The under-shelf luminaire 1 having a mounting hole is realized.

    As described above, the under-shelf lighting fixture 1 of the present invention has a wide irradiation angle because the transparent resin cover 4 has a flat and substantially U shape, and the mounting surface 9 of the tape-like LED substrate 3 has a U-shape. The tape-shaped LED board 3 can be mounted at two angles using the bent line of the U-shaped as a guide, so when installing on the front side under the shelf, wide in the back, when installing in the back Widely illuminate the lower display products on the front side.

  Further, a rectangular notch 10 provided on one surface of the end cap 5 attached to the end of the instrument body 2 is a power cord insertion hole and a mounting hole for the connector 11 of the power cord.

  Further, for installation, various support members can be easily attached at arbitrary positions by sliding the plate nuts 7 inserted into the retainer grooves 6 provided in the luminaire body 2, so Various installation methods such as a hanging type from the bracket 16, a cantilever type from the wall structure 17 of the display shelf, a magnet type to the steel shelf, and a screwing type to the wooden shelf are possible.

  In the best mode of the present invention, the mounting surface 9 of the tape-shaped LED substrate 3 is formed in a U-shape, and a plate nut 7 for screwing a support member in an arbitrary position is inserted in the longitudinal direction. A flat, substantially U-shaped polycarbonate transparent resin cover 4 covering the entire width of the mounting surface 9 of the substrate 3 is attached to the lighting fixture main body 2 made of an aluminum profile provided with the retainer groove 6. 8 is an under-shelf luminaire 1 that is attached to both ends and end caps 5 that are integrally provided with a square notch 10 that serves as a mounting hole for a connector 11 of a power cord.

  DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments that are the best mode of the present invention will be described below with reference to the drawings. FIG. 1 is an exploded perspective view showing the configuration of the under-shelf luminaire 1 according to the present embodiment as viewed obliquely from the rear. The under-shelf lighting fixture 1 of the present embodiment is roughly divided into a lighting fixture body 2, a tape-like LED substrate 3, a transparent resin cover 4, and an end cap 5.

  FIG. 2 is a perspective view showing the completed state of the under-shelf lighting fixture 1 according to the present embodiment as viewed obliquely from the rear. The transparent resin cover 4 and the end cap 5 are attached to the fixture body 2 in which the tape-like LED substrate 3 is included. In addition, a power cord connector 11 is attached to one rectangular notch 10 provided on the end cap 5, and a plate nut 7 is slidably inserted into the retainer groove 6. Yes.

  FIG. 3 is an enlarged cross-sectional view of the under-shelf lighting fixture 1. A plate nut 7 is inserted into the retainer groove 6 of the aluminum lighting fixture body 2 on which the tape-shaped LED substrate 3 is mounted, and the pair of fitting grooves 8 are inserted. The flat, substantially U-shaped polycarbonate transparent resin cover 4 is attached, and the luminaire body 2 is made of aluminum in order to dissipate some heat generated from the LED substrate 3. Yes, the transparent resin cover 4 is made of polycarbonate for heat resistance and fire prevention.

  FIG. 4 is a cross-sectional view showing the luminaire 1 and the hanging support bracket 12 installed immediately below the front surface of the shelf board 14 mounted on the shelf support bracket 16, and the tape-shaped LED board 3 is a lower display product. It is mounted on the front side of the U-shaped mounting surface 9 provided on the instrument main body 2 so as to illuminate the depth widely.

  FIG. 5 is a cross-sectional view showing the under-shelf luminaire 1 and the cantilevered support fitting 13 installed near the wall structure of the product pallet 15 directly supported by the special-shaped wall structure 17, and is a tape-shaped LED substrate. 3 is mounted on the back side of the broken line of the U-shaped mounting surface 9 so as to widely illuminate the front of the lower display product.

  FIG. 6 is a perspective view showing the end cap 5 formed integrally. The end cap 5 is a decorative member to be attached to the end of the luminaire main body 2, and is provided with a rectangular notch 10 having a contact surface opened on one surface, and the notch is provided in a power cord insertion hole or a power cord. The connector 11 also serves as a mounting member for the connector 11.

  Compared to fluorescent tubes, LEDs have a longer life and consume less power. Also, they do not use heavy metals such as mercury for disposal, and are expected to become the mainstream of future lighting fixtures as environmentally friendly light sources. The shelf lighting fixtures of the present invention, which generate less heat and emit almost no ultraviolet rays, take advantage of the fact that they do not degrade the displayed products, have good irradiation efficiency, are lightweight and easy to install in various ways. I think that it will be widely accepted by stores and the display industry immediately.
