Abstract

(57) [Summary] The present invention is a planar light-emitting device EL (electro
Luminescence), which uses a thin and lightweight illuminator with uniform illuminance and automatically blinks at night to provide a sharpness not seen in conventional signs. It is a sign board that has color and can be seen from a distance. [Objective] The present invention is intended to provide a road traffic safety facility, an emergency evacuation display, a guidance display, or the like by using a planar light-emitting body. [Structure] As shown in FIG. 4, a planar light-emitting body EL as shown in FIG. 3 is attached to a substrate such as aluminum, and a semi-transmissive film on which characters, patterns, etc. are printed is attached. Alternatively, it is a structure in which a cut-out reflection sheet is attached or the light-emitting body is housed in a housing so that the light-emitting body can be replaced as shown in FIG.

Description

[Detailed description of the device] [Industrial applications]

 The present invention relates to an improvement of an overhang or overhead type signboard or a pedestrian signboard, which is difficult to visually recognize only by a reflection type, by using a planar light-emitting body EL (electroluminescence). It is effective as a safety signboard, an emergency escape signboard, a guide display board, or the like.

[Prior Art]

 Conventional traffic sign boards include an external lighting method that illuminates a lamp with a fluorescent light source from above the front surface of the sign board, and an internal lighting method that arranges the light source inside to illuminate letters and patterns. In addition, a self-luminous type or a reflective sheet that embeds LED (light emitting diode) and blinks is attached to an aluminum substrate, and at night, there is a reflective sign board that can be viewed by using the reflected light of the headlight of a traveling vehicle. is there.

[Problems to be solved by the present invention]

 The conventional external lighting method uses an installation method in which a lighting fixture is mounted on an overhang or overhead type pillar, but it requires fixing brackets, pillars, etc., and the wind pressure load and weight must be considered in addition to the signboard. In addition, it is difficult to obtain uniform illuminance on the signboard surface. On the other hand, the internal lighting method has a problem of manufacturing and maintenance because the weight of the housing is large, the manufacturing is troublesome. In addition, the signboard using the LED has a defect that letters and patterns are dot-shaped and lack in clarity. The present invention solves the problems of the prior art as described above, and uses a planar light-emitting body (EL) which is thin and lightweight, has uniform illuminance, and does not generate heat, and is further used as a traffic sign board. It is intended to provide a function.

[Means for solving problems]

 In order to achieve the above-mentioned object, the present invention uses a planar light-emitting body (EL) and affixes it on a substrate such as aluminum and superimposes a semi-transmissive or reflective film or sheet on it. It features a self-luminous sign that does not generate heat and has a thin plate-like shape with uniform illuminance. Further, when the illuminance is lowered and it is necessary to replace the light emitter, it is possible to remove only the light emitter or attach a new light emitter and display surface on the display plate.

[Operation] In the present invention, a planar light-emitting body (EL) is used as a light source on the whole surface or a part thereof, and a semi-transmissive or reflective film or sheet is superposed on the surface light-emitting body (EL). The letters and patterns printed or cut out on the rum, resin plate, or reflective sheet can be seen clearly, and at night, the letters and patterns automatically turn on and blink, and you can see the letters and patterns from a distance through a semitransparent film or resin plate. Also, it can be confirmed by the reflected light of the headlight, and it can exert a sufficient effect as a sign board.

【Example】

 An embodiment of the present invention will be described below with reference to the accompanying drawings. 1 and 2 are examples of the layout of the signboard surface of the present invention, FIG. 3 is a perspective view of a planar light-emitting body, and FIG. 4 is a side view of a structure in which the light-emitting body is directly attached to a substrate. FIG. 5 and an enlarged view of a part of the cross section, and FIG. 5 are cross-sectional views of the side surface of the case having a structure in which the light emitter can be replaced. In these figures, 1 is an aluminum substrate, on the surface of which a surface light-emitting body 2 is provided via a double-sided adhesive layer 1 ', and during the daytime, by a storage battery storing electric power by a solar cell or by a commercial power source, at night. The surface light-emitting body 2 emits light through the electric wire 2 ', and it is displayed clearly through a semi-transmissive film on which characters, patterns, etc. are printed, or a resin plate, or the reflection sheets 3 and 3'where characters, patterns, etc. are cut out. . The electric wire 2'is connected to a control unit having a blinking transmission circuit, and blinks at night so that the displayed characters / designs can be seen from a distance. In this case, it is possible to freely set by the electric circuit whether to perform the lighting blinking operation, the lighting operation only, or the interlocking operation with other indicators. As for the luminous body 2, as a measure when the illuminance decreases with the lapse of time of use and it becomes unusable, the present invention has a thin plate shape on the entire sign plate. A new translucent film or cutout reflective sheet can be applied on top of it. If the display board has a relatively small area, it is more convenient to replace it with a new board, and if the display board has a large size, it is necessary to superimpose the new light emitting board and the marking part only on the surface at the site. Can be reused at. Also, as shown in FIG. 5, the structure in which the light emitting plate 2 attached to the aluminum plate 1 and the like is stored so that it can be removed inside the housing, and the structure can be replaced in the housing. It can be reused in.
