Abstract

PURPOSE:To prevent a shade between arranged fluorescent lamps by installing recess reflectors on boundary back sides of adjacent lamps. CONSTITUTION:A reflecting plate 8 formed by assembling a pair of reflecting plates 8a, 8b of a flat plate state formed by coating back sides of fluorescent lamps 4 supported at both ends by a socket 7 and linearly arranged at an interval A in a fluorescent lamp container 3, for example, with white gloss coating in a recess surface state is directed at its reflecting surface toward the lamps 4 and its end is so widely installed as to arrive at a glass 4a corresponding part of the lamp 4. Most of lights emitted to the plate 8 from the end side of the lamp 4 is reflected and advanced to the side of the interval A, and hence the part is brightly illuminated. Accordingly, a character of a film stuck to a shade 2 is easily read.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a showcase in which straight tube fluorescent lamps are arranged as lighting means.

[0002]

2. Description of the Related Art This type of showcase is mainly used for selling fresh foods, frozen foods, etc. in supermarkets, convenience stores, etc., and its structure is composed of a plurality of stages as shown in FIGS. A fluorescent lamp housing 3 covered with a shade 2 made of a semitransparent resin is provided in the upper part of the display room 1 equipped with the display shelves, and a straight tube type fluorescent lamp 4 is lined up with a predetermined gap. It was set up.

In the showcase having the above-mentioned structure, the fluorescent lamp 4 installed in the fluorescent lamp housing 3 illuminates the interior of the display room 1 brightly to improve the appearance of the displayed products, and a film in which the product categories are written (see FIG. By brightly illuminating the shade 2 to which (not shown) is attached, sales guidance and advertisement are also performed at the same time.

Reference numeral 5 is a reflecting member which is installed on the back side of the fluorescent lamp housing 3 and which reflects the light of the fluorescent lamp 4 forward, for example, which is formed by applying a white glossy coating to a sheet metal. . Reference numeral 6 denotes a cool air discharge port for discharging air cooled to a predetermined temperature by a cooling coil (not shown) or the like.

[0005]

However, in the conventional showcase having the above-mentioned structure, the fluorescent lamp 4 is supported by the socket 7 and is supplied with power to be turned on. Since the light is blocked and a shadow is formed, the gaps A and B between the adjacent sockets 7, 7 become dark, and when the shade 2 is seen from the front, it appears to be partially darkened and is written on the shade 2. There was a problem that the characters were difficult to read, and the solution to this problem was a problem.

[0006]

The present invention is, as a concrete means for solving the above-mentioned problems of the prior art, in a showcase in which a plurality of straight tube fluorescent lamps are arranged in a row, a boundary between adjacent fluorescent lamps is provided. The present invention provides a showcase in which a concave reflector is installed on the rear surface side of the section, and further, at least a pair of adjacent fluorescent lamps are arranged at an angle, and the rear surface side of the boundary section between the pair of fluorescent lamps is provided. It is an object of the present invention to solve the above-mentioned problems of the prior art by providing the above-described showcase in which the reflector to be installed has a reflecting surface formed into a flat surface or a gentle concave surface or a gentle convex surface.

[0007]

[Function] By the reflector installed on the back side between the fluorescent lamps,
Light emitted from the vicinity of the ends of the fluorescent lamps is reflected toward the gap side between the fluorescent lamps and illuminates this portion brightly, resulting in illumination of uniform brightness.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A showcase according to the present invention will be described in detail below with reference to FIGS. In addition, in order to facilitate understanding, in these drawings, the same reference numerals are given to the parts having the same functions as those described in FIGS.
Although FIG. 5 is also used in the description of the present invention as necessary, the description of the same mechanism as that of the prior art is omitted without departing from the understanding of the present invention.

In the first showcase according to the present invention shown in FIG. 1, both ends of the showcase are supported by the socket 7, and the gap A between the fluorescent lamps 4 and 4 linearly arranged in the fluorescent lamp housing 3 is formed. On the back side, for example, a reflecting plate 8 formed by assembling a pair of flat plate-shaped reflecting plates 8a and 8b formed by applying a white glossy coating to a concave surface, the reflecting surface of which is on the fluorescent lamp 4 side. The fluorescent lamp 4 is installed so that its end portion reaches the glass portion 4a corresponding to each fluorescent lamp 4.

In the showcase having the above-mentioned illuminating means, most of the light emitted from the end portions of the fluorescent lamps 4, 4 and hitting the reflecting plate 8 is reflected to the gap A side and travels. The part is also illuminated brightly.

Therefore, since the shade 2 has substantially the same brightness over the entire length, the characters of the film (not shown) attached to the shade 2 are easy to read, and the effect of guidance and advertisement is great.

According to the reflection plate 8 having the above structure, the reflection plate 8
The brightness of the gap A can be adjusted by adjusting the attachment angles of a and 8b or by adjusting the distance to the fluorescent lamps 4 and 4.

Further, instead of the reflecting plate 8, a reflecting plate 8c having a reflecting surface formed in a polygonal shape as shown in FIG. 2 so as to change the reflection angle may be used, or a concave curved surface as shown in FIG. 3 may be formed. It is also possible to use the reflecting plate 8d. The reflectors 8c and 8d shown in FIGS. 2 and 3 are more effective than the reflector 8 shown in FIG. 1 in spreading the reflected light to every corner of the gap A.

The second showcase according to the present invention shown in FIG. 4 is similar to the reflector 8 on the back side of the gap B between the fluorescent lamps 4 and 4 arranged in a non-linear manner at the corners. Reflector 9 dedicated to the corner formed in a flat plate shape using the above material
However, the reflective surface is directed toward the side closer to the fluorescent lamps 4 and 4, and the ends are widely installed so as to reach the glass portion 4a equivalent portion of each fluorescent lamp 4.

Therefore, most of the light emitted from the end portions of the fluorescent lamps 4 and 4 and hitting the reflecting plate 9 is reflected in the direction of the gap B and travels, and this portion is also illuminated brightly.

Therefore, in the second showcase according to the present invention, since the corner portion of the shade 2 does not become dark, the characters of the film (not shown) attached to the shade 2 can be easily read to the end. . Further, there is no discomfort due to the shadow.

Even if the reflecting surface of the reflecting plate 9 is curved so as to have a gentle concave surface or a convex surface, the same operational effect as that of the flat plate can be obtained.

By the way, since the present invention is not limited to the above-mentioned embodiments, various modifications can be made within the scope of the claims.

For example, the space between the adjacent sockets 7, 7 may be narrowed, and the fluorescent lamps 4, 4 may be arranged close to each other so that the space A is substantially eliminated. Even in the case of such an arrangement, since the light wraps around from above and below due to the reflector, the sockets 7 and 7 are not shaded.

[0020]

As described above, in the showcase of the present invention, since the reflecting plate is installed on the back side of the gap between the fluorescent lamps arranged in a row, fluorescent light is emitted even in the portion which is conventionally blocked by the socket and is dark. The light of the lamp is evenly distributed, and it is possible to make the letters written on the shade stand out evenly, which has a great effect on promoting sales.
