Description

[Detailed description of the invention]

[0001]

[Industrial application] The present invention relates to a refrigerated or frozen multi-stage show.
It relates Kesu relates showcase capable particular lighting each shelf with good brightness balance.

[0002]

2. Description of the Related Art In a refrigerated or frozen multi-stage showcase ,
The entire showcase needs to be illuminated with the appropriate brightness in order to make the products displayed on the display shelf stand out with a lighting effect or give a fresh impression.

FIG. 3 shows a layout of lights in a conventional multi-stage open showcase. In this figure, a canopy illumination lamp 3 is installed on a canopy portion 2 protruding from a ceiling 4 of the showcase body 1 to the front side, and a ceiling illumination lamp 5 is installed on the ceiling 4. . A scattering plate 17 made of a honeycomb plate or a lattice plate for scattering illumination light is attached to the lower surface of the ceiling illumination lamp 5. The canopy illumination lamp 3 and the ceiling illumination lamp 5, each of which is a straight tube fluorescent lamp, are turned on by a ballast 11 provided in the canopy section 2.

[0004] Each of the display shelves 6, which are provided in four stages in the middle,
At the lower part on the tip side of 7, 8, 9 are provided shelf lighting lamps 12 for illuminating the display shelves 7, 8, 9 and the lowermost display shelf 10, respectively. These shelf illumination lamps 12 composed of straight tube fluorescent lamps are lit by a ballast 20 provided on the lower front side of the showcase body 1. In a conventional multi-stage open showcase, a canopy lighting lamp 3, a ceiling lighting lamp 5, and a shelf lighting lamp 12 are provided.
The fluorescent lamps having the same wattage were used, and the illumination lamps 3, 5, and 12 were turned on with the same brightness.

[0005]

As described above, in the conventional multi-stage open showcase, each of the lighting lamps 3, 5, 12
Are lit at the same brightness, and the uppermost display shelf 6
Is far from the canopy lighting lamp 3 and the ceiling lighting lamp 5, and the middle and bottom display shelves 7, 8, 9,
10 is a shelf lighting lamp 12 mounted on the upper shelf
, The illuminance of the middle and bottom display shelves 7a, 8a, 9a, 10a becomes extremely high with respect to the top display shelf surface 6a, and the brightness of the entire showcase becomes unbalanced. Had become.

In the middle and bottom display shelves 7, 8, 9 and 10, where the illuminance is very bright, the wrap 16a wrapping the product pack 16 is reflected to make it difficult to see the product, and the strong light of the fluorescent lamp. Therefore, there is a problem that the product becomes thigh-colored. Arrow P indicates reflected light from the product.

The present invention has been proposed in order to solve such problems of the prior art, and has been proposed in a case .
It is an object of the present invention to provide a multi-stage showcase in which the front part of the display shelf can be lit in a vertical direction with good balance, and the products on the display shelf can be easily viewed.

[0008]

In order to achieve this object, a multi-stage showcase according to the present invention is a showcase having a plurality of intermediate shelves, wherein the uppermost display shelf of the intermediate shelves is both a fluorescent lamp. Illuminated by horizontal canopy lighting lamps and ceiling lighting lamps, and the remaining middle and bottom display shelves are illuminated by horizontal shelf lighting lamps consisting of fluorescent lamps installed at the lower end of the middle shelf. configured so an inverter ballast for lighting the shelves illumination lamps, provided with a dimmer that outputs a dimming signal to the inverter ballast, by the optical modulator, the illumination and the remaining front portion of the uppermost shelf of the middle and the bottom of the display shelf of
Make sure that the illuminance on the front
Lighting for shelves so that the illuminance at the front of the
Lamp is a configuration that will be dimming.

[0009]

According to the above construction, the illuminance of the shelf illumination lamp is adjusted by sending a dimming signal from the dimmer to the inverter ballast for lighting the shelf illumination lamp.

Thus, the illuminance at the front of the uppermost display shelf and the illuminance at the front of the remaining middle and lowermost display shelves are changed.
If words Ru can be made uniform <br/> illuminance of the front portion of the showcase in the longitudinal direction.

[0011]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a refrigerated or frozen multi-stage show according to the present invention will be described.
-A specific example of the case will be described in detail with reference to the drawings.

FIG. 1 shows a layout of lights in, for example, a middle four-stage multi-stage open showcase having a front opening . In this Figure, the canopy portion 2 are installed horizontally canopy illumination lamps 3, the ceiling portion 4 ceiling illumination lamps 5 for illuminating the shelves 6 of the top is installed horizontally. These illumination lamps 3 and 5 made of straight tube fluorescent lamps are turned on by a ceiling ballast 11 provided in the canopy portion 2.

Further, shelf illumination lamps 12 for illuminating the middle display shelves 7, 8, 9 and the lowermost display shelf 10 are horizontally installed at the lower end portion of the lower surface of each intermediate shelf. These shelf lighting lamps 1 consisting of straight tube fluorescent lamps
The light 2 is slightly illuminated by an inverter ballast 13 for shelves provided at the lower portion of the front part of the showcase body 1.

FIG. 2 shows a block diagram of a lighting circuit for lighting these illumination lamps. In this figure, a canopy illumination lamp 3 and a ceiling illumination lamp 5 are connected to a ceiling ballast 11 to which a commercial AC power supply AC is supplied, and the ballast 11 turns on the illumination lamps 3 and 5.

Each of the inverter ballasts 13 to which the commercial AC power supply AC is supplied is connected to a shelf illumination lamp 12 to which a starting capacitor 14 is connected in parallel, and a dimmer 15 dims each inverter ballast 13. Signal S1
Is supplied. Here, the inverter ballast 13 rectifies the commercial AC power supply AC to generate a DC power supply, converts the DC power supply to a high-frequency power supply, and supplies the high-frequency power supply to the shelf lighting lamp 12. The lighting output of the shelf lighting lamp 12 is
80-85% when the brightness of the canopy illumination lamp 3 and the ceiling illumination lamp 5 is 100% (all-light lighting).
The dimming ratio is controlled by the dimming signal.

In the multi-stage open showcase constructed as described above, the brightness of the illumination lamp 12 for shelves is made slightly dark, so that the illuminance on the front surface of the uppermost display shelf surface 6a and the middle and lowermost display shelves. face 7a, 8a, 9a, the previous 10a
The illuminance of the surface can be made the same, inside the showcase
Can be lit with uniform brightness in the vertical direction .

Thus, the wrap 16a of the product pack 16
There is no reflection from the object, and the entire product can be easily viewed. The ceiling ballast 11 may be configured using an inverter ballast. In addition, the present invention can be applied not only to an open showcase having four intermediate shelves but also to other showcases .

[0018]

[Effects of the Invention] As described above, according to the present invention,
The illuminance on the front of the showcase is also
Direction so that it is not in the shopper's view.
Compared to pointless conventional lighting that illuminates the depths of shelves
The advantage that the lighting effect is excellent and the product is easy to see
There is .
