Abstract

The present invention relates to a display device using a light source module that can emit natural colors by combining three primary colors of light and an optical fiber that can emit light in the middle by adjusting the total reflectance.

Recently, the necessity and demand of indoor / outdoor advertising or exhibition aids using optical media are greatly increasing. A typical display device using an optical medium is neon sign. The neon signs presented above require a separate transformer because of the beauty of neon light, but use a high voltage, and there is a risk of an accident due to a short circuit.

In addition, there is a risk of breakage because of the use of glass and there is a disadvantage that can not change the shape and color once manufactured. Generally, due to the total reflection property of the optical fiber, when light passes through one end of the optical fiber, the light reaches the other end without leaking out from the middle. At this time, if a part of the optical fiber is processed to lower the total reflection property to a partial reflection state, light will be emitted to the outside depending on the degree of processing at the corresponding part. By using a light source module that can emit natural colors by combining three primary colors of light and an optical fiber that can emit light in the middle by adjusting the total reflectance, display devices of various colors and shapes can be made safe and cheap.

The necessity and demand of indoor / outdoor advertising or exhibition aids using optical media are increasing.

A typical display device using an optical medium is neon sign. Neon sign uses the beauty of neon light, but because of the high voltage requires a separate transformer, there is a risk of accidents due to short circuit. In addition, there is a risk of breakage because of the use of glass and there is a disadvantage that can not change the shape and color once manufactured.

An object of the present invention is to provide a display device that can produce various shapes and colors using inexpensive and safe optical fibers. Furthermore, it should not be restricted by the installation space and should be able to be used by inserting or attaching to glass or acrylic as well as being used alone.

In order to achieve the above object, the present invention uses a light source module that can emit natural colors by combining three primary colors of light and an optical fiber that can emit light in the middle by adjusting the total reflection property or reflection angle. Characterized in that the optical display device can be used without significant restrictions in the installation place.

Hereinafter, with reference to the accompanying drawings will be described to facilitate the use and reproduction of the present invention through a preferred embodiment.

As shown in FIG. 1, when light enters a dense medium from a dense medium, the angle of refraction becomes larger than the angle of incidence. If the angle of incidence is greater than the critical angle (refractive angle = 90 degrees), the light does not leak to the outside at the interface of the medium, but is all internally reflected (total reflection). The closer the incident angle of light is to the critical angle, the higher the total reflectivity. The farther the incident angle of light is from the critical angle, the lower the total reflectance and the higher the partial reflectivity.

As shown in Figure 2, ordinary optical fiber transmits the incident light without emitting it to the outside.

As shown in Fig. 3, when the surface of a general optical fiber is processed to make partial reflection (the incident angle of incident light is smaller than the critical angle of the light ③ of Fig. 1), the incident light is emitted to the outside without total reflection. . In this case, the closer the incident angle of light is to the critical angle, the higher the total reflectivity. Therefore, when the surface of the optical fiber is processed to perform partial reflection, the outside according to the processed surface of the light incident on the optical fiber produced in the desired shape (letter or shape) by varying the depth, angle, interval of the processing surface The distribution and reach of the furnace can be controlled.

As shown in FIG. 4, after the optical fiber whose surface is processed to produce partial reflection is manufactured into a desired shape (letter or shape), when the light is incident by connecting the light source module to one end, the processed surface of the optical fiber is Therefore, the overall shape produced by emitting light is made.

As shown in FIG. 5, after the optical fiber whose surface is processed to produce partial reflection is manufactured into a desired shape (letter or shape), when the light is incident by connecting the light source module to both ends, the processed surface of the optical fiber is Accordingly, a display device having an overall shape manufactured by emitting light is formed. At this time, a variety of light is emitted from the processed surface of the optical fiber according to the intensity and color of the light incident from both ends.

As shown in FIG. 6, the optical fiber may be included in a transparent material (glass, acrylic, etc.) and then manufactured and used.

As shown in FIG. 7, the optical fiber can be manufactured by being used between the two transparent materials (glass, acrylic, etc.).

The necessity and demand of indoor / outdoor advertising or exhibition aids using optical media are increasing.

Neon sign, a representative display device using optical media, has the advantage of the unique beauty of neon light, but uses a high voltage, so a separate transformer is required and there is a risk of an accident due to a short circuit. In addition, there is a risk of breakage because of the use of glass and there is a disadvantage that can not change the shape and color once manufactured.

The present invention is a display device that can produce various shapes and colors using optical fibers, and is inexpensive, safe, and can freely change colors even after being installed. Furthermore, it is not limited by the installation space and can be used as a sculpture, a decoration, or an advertisement medium because it can be used alone or inserted or attached to glass or acrylic.
