The marker 1 is a glass or resin marker plate having a non-light-transmitting surface provided with a light-transmitting display portion or a transparent or semi-transparent light-transmitting surface provided with a non-light-transmitting display portion. On one side of 1a, a film-shaped reflection sheet 1b that totally reflects the incident light is attached, and on the other side, a film-shaped light diffusion sheet 1c that diffuses and transmits the incident light is attached, and The surface is processed flat to form a substantially rectangular plate with a thickness of about 8 mm. The reflection sheet 1b and the light diffusion sheet 1c may be resin reflection plates or diffusion plates.

The sign support frame 2 is a tubular body having a U-shaped cross section that is longer than at least one side of the sign 1, and has an opening 2 a having a width such that one end of the sign 1 can be attached and detached. At the same time, both edges 2b, 2b of the opening 2a are formed so that they can be joined to the outer edge of the sign 1, a space for accommodating the light guide member 3 is provided inside, and the rear surface 2c side is attached by a screw or the like. The marker 1 fixed to the body 9 and attached to the opening 2a can be fixed by a mounting screw or the like.

The light guide member 3 is composed of a rod-shaped transparent body 4 and a cover body 5. The rod-shaped transparent body 4 is made of a transparent acrylic resin so as to be a columnar body having a diameter slightly larger than the thickness of the marker 1 and slightly longer than the marker 1, and a part of the peripheral surface thereof substantially coincides with one side of the marker 1. The joint surface 4a is provided as a flat surface, the other peripheral surface portion is used as a curved surface 4b, and a guide fixing groove 4c extending in the longitudinal direction is provided at an intermediate portion of the curved surface 4b. 4d is formed so that the connecting fitting 8 of the optical fiber cable 6 can be attached thereto.

In order to enhance the diffusion effect of the light emitted from this surface, the bonding surface 4a is provided with fine irregularities formed by an appropriate method and means, and is a rough surface through which light is diffused and transmitted. Has been formed. The irregularities can be formed by an appropriate method such as rubbing the surface with a sandpaper, scratching an arbitrary position, or attaching a light diffusion sheet or a diffusion plate.

The cover body 5 has substantially the same length as the rod-shaped transparent body 4 so that it can be bonded to the curved surface 4 b of the rod-shaped transparent body 4 by glass, resin, or a metal material to cover the entire surface. A cylindrical body having a substantially C-shaped cross section, preferably a curved body having an opening 5a with the same curvature as that of the curved surface 4b, and having a rod-shaped transparent body at an intermediate portion of an inner surface joined to the curved surface 4b. A convex strip 5b that fits into the groove 4c is provided, and the inner surface is formed as a reflecting surface having a high light reflectance and the outer surface is formed as a light shielding surface. The cover body 5 may be provided integrally with the sign support frame 2.

The light guide member 3 including the above-mentioned members is obtained by inserting the rod-shaped transparent body 4 into the protrusion 5 b of the cover body 5 by inserting the groove 4 c into the inside of the cover body 5 through the end opening. With the joint surface 4a exposed to the opening 5a of the cover body 5 and the curved surface 4b entirely joined to the inner surface of the cover body 5, the end portions 4d and 4d are projected at both ends of the cover body 5 to prevent the predetermined portion inside the cover body 5. It is designed to be held in the position.

The optical fiber cable 6 has its input end 6a connected to the light source 7, and its output end 6b attached to one end 4d of the rod-shaped transparent body 4 housed in the sign support frame 2 via the connection fitting 8. Moreover, it is fixedly attached to the connection port of the sign support frame 2. As shown by the broken line in FIG. 2, if the two optical fiber cables 6 and 6 connected to the light source 7 are connected to both ends 4d and 4d of the rod-shaped transparent body 4, the amount of light incident on the light guide member 3 is increased, The brightness of the marker 1 can be increased, which is preferable.

The light source 7 is installed at a location distant from the skeleton 9, and various incandescent lamps, discharge lamps and the like can be used according to the required light quantity and output.

The present example is configured as described above, and construction is performed by the following procedure. First, the rod-shaped transparent body 4 is attached to the cover body 5 to form the light guide member 3, and the light guide member 3 is housed in the sign support frame 2 by an appropriate fastening means. Next, the marker support frame 2 is fixed to the skeleton 9, and the marker 1 is fixed to the edges 2b and 2b of the marker support frame 2 by bonding one surface to the bonding surface 4a of the rod-shaped transparent body 4. . The light guide member 3 and the marker 1 may be fixed to the marker support frame 2 and then attached to the body 9.

Then, the output end 6 b of the optical fiber cable 6 is attached to the end 4 d of the rod-shaped transparent body 4 via the connection port 8 and fixed to the connection port of the sign support frame 2. When the optical fiber cable 6 is attached only to one end 4d of the rod-shaped transparent body 4, the other end 4b of the rod-shaped transparent body 4 is covered with a reflecting member (not shown). Further, the optical fiber cable 6 is wired and the input end 6a thereof is connected to the light source 7 to complete the construction.

According to this configuration, the light source light output from the light source 7 enters the fiber from the input end 6a of the optical fiber cable 6, is transmitted through the fiber without deteriorating the output, and is output from the output end 6b. It is incident on the light guide member 3. The light source light incident on the light guide member 3 spreads from the output end 6b and travels straight through the same member, and a part of the light enters the joint surface 4a which is a boundary surface with the marker 1 as it is and is formed on the surface. The light is refracted by the unevenness and is incident on the marker 1, or is reflected by the inner surface of the cover body 5 and then is incident on the bonding surface 4a, and similarly is refracted by the unevenness and is incident on the marker 1 all over and is incident on the marker 1. The marker 1 can be uniformly emitted by the light source light.

Therefore, since the medium for absorbing the light source light is not interposed between the rod-shaped transparent body 4 of the light guide member 3 and the sign 1, there is no transmission loss of the light source light between the two members, and the optical fiber cable 6 is provided. The label 1 can be efficiently emitted by the light transmitted from In addition, since the light rays in the rod-shaped transparent body 4 can be made incident on the marker 1 by the refraction effect of the unevenness 4d provided on the bonding surface 4a of the rod-shaped transparent member 4, the light guide member 3 and the marker support frame for housing the same. 2 can be provided in a smart shape that is approximately equal to the length and thickness of the sign 1.

In the above structure, the marker 1 and the rod-shaped transparent body 4 can be formed to have appropriate sizes and lengths as long as they can be joined to each other. As shown in FIG. 4, the marker 1 is formed by using only one surface as a light emitting surface as described above, and as shown in FIG. 4, the marker plates 1a are superposed with the reflection sheet 1b sandwiched therebetween, and light is diffused on the outer surfaces of both marker plates 1a. It is possible to use a sheet in which the sheets 1c and 1c are attached and both sides are formed as light emitting surfaces. In this case, the bonding surface 4a of the rod-shaped transparent body 4 needs to be formed to have a width obtained by stacking two marker plates 1a so that the side surfaces of the marker 1 can be bonded.

The amount of light emitted from the marker 1 can be adjusted by adjusting the amount of light emitted from the light source 7 or replacing the lamp with a lamp having a different output. In addition, an automatic lighting circuit may be incorporated to automatically turn on and off the light.

[0024]

[Effect of device]

 As described above, according to the sign light-emitting device of the present invention, the sign can be formed with an appropriate thickness and size without being restricted by the type and size of the light source used, and the sign design can be designed in various ways. Can give sex.

Since the rod-shaped transparent body of the light guide member is directly bonded to one side surface of the sign and no medium for absorbing the light source is interposed between the sign and the rod-shaped transparent body, the light source light is transmitted between both members. There is no transmission loss of light, and almost all of the light transmitted from the optical fiber cable can be made incident on the sign, and the sign can efficiently emit light. Further, since the light rays in the rod-shaped transparent body can be incident on the sign by the refraction effect of the concavities and convexities provided on the bonding surface of the rod-shaped transparent body, the light guide member and the sign support frame that houses the light guide member can be adjusted to the length and thickness of the sign. It can be provided in a substantially equal smart shape.

Further, since it is not necessary to provide a light source or power wiring adjacent to the sign, the installation space can be effectively utilized, the installation work such as mounting and wiring can be facilitated, and maintenance such as lamp replacement can be facilitated. Since the light source can be installed at a remote location, the installation location, the type of light source used, the output, etc. can be freely selected, and the flexibility in sign design can be expanded.
