Abstract

PURPOSE:To make an beautiful advertisement display not only in the night, but also in the day by forming a colored light emission body by combining a light source and a transparent body together. CONSTITUTION:The light source 11 is provided in a cylindrical light source part 1 and its inner peripheral wall surface is formed into a metallic mirror to improve the projection efficiency of light. The columnar transparent body 2 which is made of plastic and coupled coaxially with the light source part 1 receives the light projected by the light source part 1 on the end surface coupling with the light source part 1, transmits the light inside, and scatters it in circumferential directions. The transparent body 2 is provided with, for example, a red transparent color layer 21 as its surface layer and the light from the inside is passed through this color layer 21, and scattered and projected. The transparent body 2, therefore, emits light in one or plural colors corresponding to the light emission color of the light source 1 and/or the color of the transparent body 2.

Description

[Detailed description of the invention]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an advertising display body suitable for displaying advertisements not only at night but also during the day.

0002

2. Description of the Related Art Neon signs have been used for displaying advertisements, especially at night. This neon sign uses a discharge tube filled with gas to create a color unique to the gas, thereby creating a color advertisement.

0003

[Problems to be Solved by the Invention] However, although this neon sign is clearly displayed at night, the transparent glass tube is exposed on the surface during the day, giving the viewer a cluttered feeling. In order to avoid this, some advertisements have been devised by placing a picture on the background of the discharge tube so that it does not look out of place, but it still leaves the display feeling cluttered.

Incidentally, in recent years, components with high brightness have appeared on the market as light emitting sources. For example, a halogen lamp as a small light source is one of the typical examples. These halogen lamps are widely used in automobile headlights, road night lights, and the like. By making light emitted from such a high-intensity light source incident on a rod-shaped or plate-shaped transparent body, the transparent body can be used as a light-emitting body. An example of this is the red rod-shaped flashlight (a light source placed inside a cylindrical tube) used to guide cars through construction zones.

[0005] An object of the present invention is to provide an advertising display body that combines such a light source and a transparent body to form a colored light-emitting body, thereby realizing a clear advertisement display not only at night but also during the day. The goal is to provide the following.

[0006]

[Means for Solving the Problems] To achieve this, the advertising display of the present invention is composed of a light source section and a transparent body that receives the light emitted from the light source section, scatters it, and radiates it to the outside. The transparent body emits light in one color or in a plurality of colors depending on the emission color of the light source section and/or the color of the transparent body.

[0007]

[Examples] Examples of the present invention will be described below. FIG. 1 is an explanatory diagram of a plastic color bar as an advertising display according to one embodiment. Reference numeral 1 denotes a cylindrical light source section, inside of which a light source 11 such as a 250W white light source or a halogen lamp is provided, and the inner circumferential wall surface is a metal mirror to improve light emission efficiency. Reference numeral 2 denotes a cylindrical transparent body made of plastic that is coaxially connected to the light source section 1, and the light emitted from the light source section 1 enters from the end surface connected to the light source section 1 and is transmitted inside and directed toward the surroundings. Scatter. This transparent body 2 is provided with a transparent color layer 21 of red color, for example, on the surface layer, and light from inside is transmitted through this color layer 21.
Since the light is scattered and emitted via the color layer 1, light of the color (for example, red) of the color layer 21 is emitted.

By the way, when light passes through a scattering material such as plastic, the intensity of the light weakens depending on the distance. The amount attenuated by this scattering is expressed by the following equation. Iout = Io[1-exp(α・t)] where I
out is the amount of light scattered at the distance t, Io is the amount of light emitted from the light source, and α is the attenuation coefficient due to scattering. Therefore,
Since the amount of light emitted from the scatterer Iout is a function of the distance from the light source, the scattered light becomes weaker at a farther location.

In recent optical communications technology, plastic optical fibers have begun to be used for short distance communications. Some of these materials have an attenuation rate of about -40 dB/Km, and based on this value, the amount of light at 10 meters away will be approximately 67%, which means that a considerable amount of light will be transmitted. If structure 2 is adopted, nearly uniform light emission (scattering)
A transparent body with intensity distribution can be obtained.

In the device shown in FIG. 2, a transparent body 3 made of plastic has a light transmitting portion 31 having high light transmittance as the central material, and a scattering layer 32 is provided on the outer surface of the light transmitting portion 31.
Further, a color layer 33 is provided on the outside thereof. Note that the distal end surface 34 of the transparent body 3 is a mirror surface so that transmitted light is confined within the rod-shaped body. This made it possible to realize a light emitting body that was uniform in the length direction.

[0011] As a method of manufacturing the light transmitting portion 31 and the scattering layer 32 of such a transparent body 3, a double crucible is used, and the material for internal transmission as the light transmitting portion 31 is placed in the center crucible, and the scattering layer 32 is A method can be adopted in which the following materials are simultaneously melted in an external crucible and then blown out from a nozzle.

[0012] If one of the longitudinal sides (back side) of the structure shown in Fig. 2 is made a mirror surface, no light will be emitted to the back side, and the amount of light scattered to the front side will increase accordingly. , the brightness increases. For advertising that is attached to a panel, the attached part on the panel side does not need to function as a light emitter, so that part should be made a mirror surface as described above to prevent light scattering from there. This is preferable because the amount of scattered light from the surface increases.

[0013] The transparent bodies 2 and 3 may also be made of thermoplastic P.
When made of C (polycarbonate) or PMMA (acrylic resin), it becomes possible to bend them by heating, and characters, figures, and symbols for advertising can be formed. During the daytime, these characters are used as chromatic-colored advertisements, and at night, they are displayed as luminescent advertisements in the same color. Note that if flexible materials are used for the transparent bodies 2 and 3, they can be bent into any shape at room temperature to form similar characters or the like.

FIG. 3 shows an improvement of the transparent body 3 shown in FIG. 2, in which the outer diameter of the central light transmitting portion 31 is made smaller as it reaches the tip surface 34, and the inner diameter of the scattering layer 32 is correspondingly increased. It has a tapered shape. In this example, the light transmitted through the light transmission section 31 is efficiently distributed to the scattering layer 32,
A rod-shaped transparent body that is relatively independent of the distance from the light source section 1 can be realized. That is, the brightness of the scattered light becomes substantially uniform in the length direction, and the sense of discomfort can be reduced.

[0015] As the light source section 1 described above, a colored one can be used. As a method for realizing this, there is a method of inserting a color filter at the interface between the light source section 1 and the transparent bodies 2 and 3. In this method, transparent body 2,
If the color layers 21 and 33 of No. 3 are not used and are made colorless and transparent, the color of the filter can be used as the display color, and the color can be selected from various colors depending on the color of the color filter. Also,
If the color layers 21 and 33 are used, the color of the light emitted from the transparent bodies 2 and 3 will be a composite color of those colors and the color of the filter. For example, by rotating the color filter between the light source section 1 and the transparent bodies 2 and 3, it is possible to realize multi-colored coloring that changes every moment over time, which can increase the attention-grabbing effect for advertising purposes. can. This is a big advantage compared to conventional neon signs, which cannot change color after installation.

Further, the shape of the transparent bodies 2 and 3 is not limited to a cylindrical shape, but may be a prismatic shape. Also, even if it is plate-shaped, if you place the light emitting source at an appropriate location,
Color materials for displaying planar advertisements can be realized. Further, the color layers 21 and 33 of the transparent bodies 2 and 3 are not limited to a single color, but may have a plurality of colors in which characters, figures, and symbols are displayed using a plurality of colors.

[0017]

As described above, the advertising display of the present invention has the advantage that it is possible to realize a display that is highly visible and beautiful not only at night but also during the day.
