[Industrial applications]

The present invention relates to a method of illuminating an inverted display, and more particularly to a method of illuminating an inverted display that performs display by inverting a colored display surface.

[Conventional technology]

2. Description of the Related Art Conventionally, for example, a four-color display is used as an inversion type display that performs color display by inverting a display surface.

FIG. 3 is a perspective view of a conventional four-color display, and FIG.
FIG. 3 is an enlarged perspective view of the four-color display of FIG.

In these figures, a four-color display 1 includes a plurality of rotating bodies 2 arranged in a matrix as display elements.
Is configured to be inverted around the center. The rotating body 2
It has four display surfaces 2a, 2b, 2c, 2d, each of which is white, red,
Any color such as green or blue is applied, and the adjacent rotating bodies 2 are arranged at intervals. In order to perform the display, energization of an unillustrated electromagnet provided inside the rotating body 2 is controlled so as to be attracted and repelled by a permanent magnet (not shown) attached to the rotating body 2. Is rotated about the axis 3 to a desired position. Further, as the four-color display 1, for example, about 120 to 160 rotating bodies 2 are arranged in the vertical direction and about 240 to 320 rotating bodies 2 are arranged in the horizontal direction to display a graphic attached to a wall or the like.

Such a four-color display 1 employs an external illumination system or an internal illumination system so that the display can be seen even at night.

In the external illumination system, as shown in FIG. 5, an illuminating lamp 4 is disposed on the lower side or the like, and the display surfaces 2a and 2 are externally provided when it is dark such as at night.
This is a method of illuminating b, 2c, and 2d.

In the internal illumination system, as shown in FIG. 6, the display surfaces 2a, 2b, 2c, and 2d of the respective rotating bodies 2 are made of a material such as resin and have transparency, and a built-in lamp 5 is provided therein. When the camera is used outdoors, the built-in lamp 5 is not turned on in a bright atmosphere in the daytime, but it is turned on in darkness at night to make it easier to see.

[Problems to be solved by the invention]

In the conventional external illumination system of the four-panel display 1, the distance from the display surface 2a, 2b, 2c, 2d of the rotating body 2 differs depending on the position of the illumination lamp 4, and the illuminance is not uniform. That is, the display screens 2a, 2b, 2c, and 2d near the lighting lamp 4 are bright, but the display screens 2a, 2a,
2b, 2c, 2d darkens.

On the other hand, in the internal illumination system of the four-panel display 1, the color temperature of the normally used built-in lamp 5 is low, and the display surfaces 2a, 2b, 2c, Since the light passes through 2d, the color becomes yellowish or whitish, and there is a problem that the color is different between the illumination by natural light in the daytime and the case where the built-in lamp 5 is turned on at night.

Therefore, an object of the present invention is to provide a method of illuminating a reversal display device that can uniformly illuminate a display surface and does not cause a color difference.

[Means to solve the problem]

The above object is to provide a method of illuminating an inversion display in which an image is displayed by inverting a rotating body having at least a colored display surface as an axis. The problem is solved by a method for illuminating an inverted front display device, comprising arranging a lamp and illuminating a display surface of an adjacent rotating body through an illumination window with the built-in lamp.

[Action]

In the present invention, by illuminating the display surface of the adjacent rotator through the illumination window with the built-in lamp disposed on each rotator, the distance from the internal lamp in each adjacent rotator becomes the same, and the illuminance is reduced. The colors are almost the same because they are uniform and are illuminated from the outside.

〔Example〕

Hereinafter, the present invention will be described in detail with reference to an embodiment shown in the drawings.

FIG. 1 is a principle diagram showing a method of illuminating an inversion type display according to the present invention.

In FIG. 1, an inversion type display 11 has a display surface 12 such as a rotating body 12 constituting a display element arranged in a matrix.
a (12b, 12c, 12d) is configured to be illuminated by the built-in lamps 15 provided on the adjacent rotating bodies 12, respectively.

FIG. 2 is a diagram showing a method of illuminating an inversion display according to an embodiment of the present invention. Parts corresponding to FIG. 1 are denoted by the same reference numerals.

In FIG. 1, an inverted display 11 is applied to a four-sided display, and a rotating body serving as a display element as in the conventional example.
A large number of 12 are arranged in a matrix, and are configured to be inverted around the axis 13. The rotating body 12 is
It has four rectangular display surfaces 12a, 12b, 12c, and 12d, each of which is given a color such as white, red, green, or blue, and has an illumination window 14 formed at a corner (four locations). ) Has been. Also,
Inside the rotating body 12, a built-in lamp 15 fixed to the shaft 13 is disposed. Then, the rotating body 12 has a display surface 12a, 12b, 12c,
It is configured so that it can be seen from the inside through the illumination window 14 and slightly inclined downward and inverted.

In the illumination method of the inverted display having the above-described configuration, the display surfaces 12a, 12b, 12c, and 12d of the rotating body 12 are illuminated by the built-in lamps 15 arranged inside the adjacent lower rotating body 12, respectively.
Irradiated through. Therefore, each display surface 12a, 12b, 12c, 12
d has the same distance from the built-in lamp 15 in each adjacent rotating body 12, uniform illuminance, and external illumination. become.

In the above embodiment, a four-color display is described as an example. However, the scope of the present invention is not limited to this, and it is sufficient if the reversible rotator has at least a colored display surface.

Further, in the four-color display of the above-described embodiment, the built-in lamp 15 fixed to the shaft 13 is provided inside, but the built-in lamp that is inverted with each display surface may be provided on the back surface.

〔The invention's effect〕

As described above, according to the present invention, in the inverting display, the display surface of the adjacent rotator is illuminated through the illumination window by the built-in lamp provided on each rotator, thereby providing the illuminance of each display surface. Is uniform and illumination is provided from the outside, so that there is an effect that almost the same color is obtained.
