As shown in FIG. 2, upper and lower reflectors 30 are provided above and below the central reflector 20 with screws 39, 39, respectively, in connection holes 25, 25, 34, 34,. It is connected so that the position can be adjusted upward and downward by being inserted and fastened, and on both sides of the upper and lower reflectors 30, 30, the side reflectors 40 connect the screws 49, 49 with the connection holes 35, 3, respectively.
5, 44, and 44 are connected so that the position can be adjusted to the side by being fastened, and assembled into a substantially box shape having an open front surface. Forwardly, the end reflectors 50 are connected so that the directions thereof can be adjusted and the positions thereof can be adjusted sideways by fastening screws 59 through the connection holes 54 and 44. The end reflector 50 may be connected in front of the side end portions of the upper and lower reflectors 30 by inserting screws 59 into the connection holes 54 and 35.

Accordingly, the reflector 19 slides the entire height and width of the central reflector 20, the upper and lower reflectors 30, 30, and the side reflectors 40, 40 upward and downward and to the side. , And the orientation and arrangement of the end reflectors 50, 50... Are adjusted by rotating and sliding with respect to the side reflectors 40, 40, so that the light irradiation range is the size of the advertisement display board 9. Thus, it is possible to easily cope with the above and to minimize the installation space. For example, as shown in FIG. 8, the height of the reflector 19 (the lighting device 10) is reduced with respect to the advertisement display board 9 of the sample display window 4, and the height of the reflector 19 (illumination device 10) is reduced. Can increase the height of the reflector 19 (the lighting device 10).

As shown in FIGS. 1 and 2, the reflector 19 has the sockets 16, 16 projecting forward from the socket projecting holes 27, 27 on the front surface of the mounting frame 14.
Screws 29, 29 ... are fixed to fixing holes 24, 24 ..., 15, 15
… And are fastened and fastened. Then, the linear fluorescent lamp 12 has sockets 16, 16 at both end portions.
The reflector 19 is mounted on the mounting frame 14 so as to be engaged with the reflector 19 and is disposed in front of the central reflecting portion 22 of the reflector 19.

In the lighting device 10 configured as described above, the light radiated forward from the fluorescent lamp 12 is directly radiated to the back surface of the advertisement display board 9, and the rear, upper and lower, The light emitted to the side is reflected by the rear reflectors 21, 21, 31, 31, 41, 41, the central reflector 22, the upper and lower reflectors 32, 32, the side reflectors 42, 4 of the reflector 20.
2, the light is reflected forward and illuminated on the back surface of the advertisement display board 9. However, since the reflection surface of the reflector 19 has a specular gloss, the difference in intensity between the direct light and the indirect light is small. On the other hand, it is possible to irradiate the light having substantially the same intensity to the front part and the part distant from the fluorescent lamp 12.

Further, the light emitted from the fluorescent lamp 12 to the upper side is reflected forward and downward by the end reflectors 50, 50, and the light emitted from the fluorescent lamp 12 to the lower side is reflected at the end. Board 5
At 0 and 50, the light is reflected forward and upward to irradiate both end portions of the advertisement display board 9, and shadows of the sockets 16 and 16 make it difficult for the direct light of the fluorescent lamp 12 to be irradiated. ,
50 can be suitably irradiated.

Therefore, the entire surface of the flat advertising display plate 9 can be uniformly illuminated from behind by the light of the linear fluorescent lamps 12, thereby preventing the image of the fluorescent lamps 12 from appearing on the advertising display plate 9. Thus, the visibility of the advertisement content can be further improved. In addition, since the light irradiation range can be easily made to correspond to the size of the advertisement display board 9, the advertisement display board 9 can be efficiently illuminated without waste.

FIGS. 10 and 11 show a second embodiment of the present invention. The same parts as those in the first example are denoted by the same reference numerals, and description thereof will be omitted. 10 and FIG.
In FIG. 1, the end reflectors 50 are omitted.

The side reflectors 140 of the reflector 119 of the lighting device 110 are vertically divided into two parts, and the side reflectors 140 are divided into upper and lower reflectors 30 according to the width of the advertisement display board 9. The position of the side reflector 140 can be adjusted to the side with respect to the center reflector 20 together with the upper and lower reflectors 30 in accordance with the height of the advertisement display board 9 in addition to being adjustable to the side. It is possible. In addition, the side reflector 140 has
The upper and lower reflectors 143 are composed of the rear reflector 41 and the side reflector 4.
2 is formed integrally with the upper and lower surfaces,
The rear reflecting portion 41 is formed in a horizontally long flat plate shape that protrudes forward from upper and lower outer edges and is slightly inclined outward.

In the above embodiment, the connecting holes 2
5, 34, 35, 44, and 54 are formed into an oval shape, and the case where the height, width, arrangement, orientation, and the like of the reflector 19 can be continuously adjusted has been described. May be provided in parallel, so that the height and width of the reflector, the arrangement and orientation of the end reflectors, and the like can be adjusted in a stepwise manner.

[0025]

As described above, in the advertising display board lighting device according to the present invention, the central reflector, the upper and lower reflectors, and the side reflectors are arranged behind the fluorescent lamp behind the advertising display board. hand,
By arranging the reflected light in the forward direction, the back surface of the advertising display panel is illuminated with the direct light of the fluorescent lamp and the reflected light to illuminate the advertising display panel from behind, but the reflective surface has a specular gloss. By using the central reflector, upper and lower reflectors and side reflectors having, it is possible to irradiate the direct light and the reflected light of the fluorescent lamp with the same intensity, and the central reflector, The upper and lower reflectors and the side reflectors are interconnected so that the height and width can be adjusted according to the size of the advertisement display board, so that the light irradiation range can easily correspond to the size of the advertisement display board. be able to. Therefore, the entire surface of the flat advertising display plate can be almost uniformly illuminated with the light of the linear fluorescent lamp without waste, and the installation space can be minimized.

Further, an end reflector having a specular gloss on the reflection surface is connected to the upper and lower reflectors or the side reflectors so that the orientation or arrangement can be adjusted according to the size of the advertisement display board, and the fluorescent lamps By arranging it on the upper or lower side and irradiating the reflected light to the lower front or upper front of the fluorescent lamp, it reflects on the side edge of the advertising display board where direct light of the fluorescent lamp is difficult to irradiate Light is preferably applied, and the entire surface of the advertisement display board can be more uniformly illuminated.

When the advertising display board mounted on the vending machine is illuminated from behind, it can be suitably installed in a narrow space such as inside the vending machine.
