The optical transmission tube 1 has a band-shaped reflective layer 4 extending in the longitudinal direction of the tube between a core 2 and a tubular cladding 3 covering the core. The reflection layer 4 may be formed in a state in which the reflection layer 4 slightly penetrates into the core 3 from the surface of the core 3.

The reflection layer 4 is disposed on the side of the light transmission tube 1 opposite to the side from which light is to be emitted.
In this embodiment, the reflective layer 4 has a width that is about half the circumference of the core 2 of the light transmission tube 1, and light is hardly leaked from the reflective layer 4 side.

As the material (core material) forming the core 2, a transparent material having a higher refractive index than the material (cladding material) forming the tubular cladding 3 is used. Is appropriately selected and used depending on the purpose.

As specific examples of the core material, polystyrene,

On the other hand, the clad material can be selected from transparent materials having a low refractive index, and examples thereof include organic materials such as plastics and elastomers.

Specific examples of the clad material include polyethylene, polypropylene, polymethyl methacrylate, polymethyl methacrylate, polyvinyl chloride, polyvinylidene chloride, polyvinyl acetate, polyethylene-vinyl acetate copolymer, polyvinyl alcohol, and polyethylene. -Polyvinyl alcohol copolymer, fluororesin, silicone resin, natural rubber, polyisoprene rubber, polybutadiene rubber, styrene-butadiene copolymer, butyl rubber,
Halogenated butyl rubber, chloroprene rubber, acrylic rubber, ethylene-propylene-diene copolymer (EPD
M), acrylonitrile-butadiene copolymer, fluorine rubber, silicone rubber and the like.

Of the above core materials and cladding materials, polystyrene, polycarbonate, styrene- (meth) acryl copolymer ( MS polymer) and the like, and the clad material is (meth)
Acrylic polymers are preferred.

The reflection layer contains a white pigment and a scattering material (meta).
It is preferable to use an acrylic polymer.

Examples of the white pigment and the scattering material include organic polymer particles such as silicone resin particles and polystyrene resin particles, metal oxide particles such as Al ₂ O ₃ , TiO ₂ and SiO ₂ , and sulfate particles such as BaSO _4. And carbonate particles such as CaCO _3, etc., and one of these can be used alone or in combination of two or more.

In consideration of reflection efficiency, coextrusion workability, and the like, the average particle size of the particles of the white pigment and the scattering material is preferably about 0.1 to 200 μm, particularly preferably about 0.5 to 50 μm. The content in the reflective layer constituting material (reflective material) is about 0.5 to 20% by weight, particularly 1 to 10% by weight.
It is preferred that it is about.

Although the thickness of the reflection layer 4 is not particularly limited,
The thickness is preferably 0 to 200 μm, particularly preferably 50 to 100 μm. If the thickness is too small, the reflected light decreases and the luminance decreases.If the thickness is too large, the reflected light increases and the luminance increases. In some places, the brightness may be disadvantageously reduced.

The diameter of the core 2 is not particularly limited, but is usually about 2 to 30 mm, especially about 5 to 15 mm.
The wall thickness of the tubular cladding 3 is usually about 0.05 to 4 mm, especially about 0.2 to 2 mm.

In this light transmission tube, a reflective protective layer may be formed on the outer surface of the tubular clad 3 so as to cover the peripheral surface that does not emit light (the peripheral surface on the side of the reflective layer 4). In the case of an optical transmission tube having such a reflective protective layer formed thereon, when there is a defect such as a pinhole in the reflective layer 4, light leaking to the back side of the reflective layer 4 through this defective portion or the reflective layer 4 has By reflecting the light leaking from the side portion with the reflective protective layer, the loss of light can be reduced, and the brightness on the opposite side of the reflective layer 4 can be further increased.

As a constituent material of the reflective protective layer, a material that does not transmit the light leaked from the reflective layer 4 to the outside, does not absorb the light, and reflects the light efficiently is preferable. And a metal foil or metal sheet of silver, aluminum, or the like, or a coating film in which the above-described scattering particles that scatter light are dispersed.

To manufacture this light transmission tube, for example, a three-color extruder having three screw parts is used, and a core material, a clad material, and a reflecting material containing a white pigment or a scattering material are introduced into the extruder. The core material may be extruded into a cylindrical shape, the reflective material may be extruded into a plurality of strips on the outer peripheral surface of the columnar core material, and the clad material may be extruded into a tube shape covering the core material and the reflective material.

According to this method, three types of materials having different refractive indices and physical properties can be simultaneously extruded, and a laminated structure having three types of functions can be formed at a time.
Moreover, since the respective materials are laminated in a softened state, an optical transmission tube having excellent adhesion between the respective layers can be efficiently manufactured.

When a reflective protective layer is formed, a metal foil or a metal sheet may be attached after the extrusion molding, or a coating material in which scattering particles are dispersed may be applied. It is also possible to form a hydrophilic protective layer.

The optical transmission tube may be manufactured by a method other than the above.

By lighting one, two or three of the light emitting diodes 12, 13, and 14, the light transmission tube 1 is turned on.
Can emit light of various colors. When only one light emitting diode 12, 13, 14 of the light source unit 11 is turned on, light of the color of the diode is radiated, and when two diodes are turned on, a light of an intermediate color in which they are mixed is emitted. Light is emitted and white light is emitted by turning on the three diodes.

When the light source units 11 are provided at both ends of the light transmission tube 1, light with high luminance is emitted over the entire length of the light transmission tube 1. When the light transmission tube 1 is short, it is sufficient to provide the light source unit 11 only at one end of the light transmission tube 1, but when the light transmission tube 1 is long, it is preferable to provide it at both ends.

When the light source units 11 are provided at both ends of the light transmission tube 1, the light emission colors of the light source unit 11 at one end and the light source unit 11 at the other end may be different. For example, when red light is supplied from one end and blue light is supplied from the other end, red light is emitted near one end of the light transmission tube 1 and blue light is emitted near the other end. Near the middle of the tube 1, purple light is emitted. Therefore, a subtle hue and color tone can be expressed by one light transmission tube.
