の広い用途がある。2. Description of the Related Art Conventionally, as shown in FIG. 3, a light scatterer 2 is connected to a tip of an optical transmission tube or an optical fiber 4 by a joint 3 as shown in FIG. A lighting method is known in which light is transmitted to the light scatterer 2 and the light incident on the light scatterer 2 is emitted from the entire outer peripheral surface of the light scatterer 2, which is decorative lighting, underwater lighting, explosion-proof lighting, It has a wide range of applications such as displays and special lighting.

The material is made into a rod shape, a spherical shape, a polyhedral shape, a plate shape, or the like.

全体から光が出るものである。In such a light scatterer, the transparent matrix itself causes total reflection of light at the interface with the air and transmits the light without leaking it to the outside, but the light travels in the matrix. At this time, light is scattered at the interface with the transparent material that is uniformly dispersed in this matrix, and a high-angle component where the angle between the interface of the transparent matrix and the air does not satisfy the condition of total reflection is created. And the light is emitted from the entire light scatterer.

体を提供する。In order to achieve the above object, the present invention provides a transparent matrix in which a transparent material having a refractive index different from that of the matrix is uniformly dispersed in a block shape or a column shape. One feature is that the light scatterer that emits the light incident from the one-incident part from the entire outer peripheral surface is surrounded by a thin hollow body formed of a light-transmittable material at a predetermined distance from the light scatterer.

えるという不都合はないものである。The light-emitting body of the present invention has a light-transmitting tube or the like connected to one end of a light-scattering body formed in a block shape or a column shape,
Light transmitted from this tube and incident from one end is scattered inside the light scatterer and emitted from the entire outer peripheral surface of the light scatterer. The light scatterer is made of a material capable of transmitting light. Since it is surrounded by a hollow body, the light emitted from the light scatterer further passes through the hollow body surrounding the light scatterer and is diffused to the outside. The light diffuses uniformly in the direction, so that the hollow body itself becomes as if it were the light emitting body itself. In this case, if a light bulb is used instead of the light scatterer, the light bulb can be seen through the hollow body, but the light emitting body of the present invention does not have the light source (light scatterer) sight. .
