Various lighting devices have been proposed that utilize the light transmission properties of fibers. Further, a lighting device using a light transmission rod made of quartz glass rod, optical glass rod, silicone resin rod, acrylic resin rod, etc. has been proposed in Japanese Patent Application Laid-Open No. 118806/1983. Conventionally, a lamp with a reflector has been generally used as a light source for the above-mentioned lighting equipment, and the light emitted from the lamp with a reflector is transmitted to a fiber bundle or an optical transmission rod (hereinafter referred to as an optical transmission body). is incident on the end face of At this time, the fiber had a problem in that the transmitted light leaked due to scratches and dirt on the surface. For this reason, a cladding layer is provided on the outside of the main body core to prevent scratches and dirt from adhering to the surface.

れらの問題を解決することが提案されている。 On the other hand, similar to fibers, optical transmission bodies also have the problem of leakage of transmitted light due to scratches or dirt on the surface. Furthermore, leakage of light when holding and fixing the optical transmission body has become a problem, and it has become necessary to improve the selection of materials for fixing and the fixing structure. Furthermore, in order to be assembled into other equipment as a lighting device, it is necessary to ensure vibration resistance and impact resistance, so by providing a clad layer on the optical transmission body and holding the periphery with silicone resin, etc. It is proposed to solve the problem.

However, in the structure in which the cladding layer 100 is provided in the optical transmission body, the diameter of the optical transmission body is generally about 10 mm.
As a result, the angle of acceptance (acceptance cone) becomes narrow, making it inefficient. That is,
To explain based on FIG.
When the cladding layer 100 is provided, the cladding layer 100
The angle at which light can be received changes compared to the acceptance angle α of the case where the angle is not provided, and the acceptance angle β becomes narrower than α (α
β), cannot be combined efficiently with high-output, short-throw lamps.

う問題点があつた。 In addition, in the case of a structure in which the cladding layer 100 is not provided, loss due to light leakage can be reduced by directly covering and holding the optical transmission body with a high brightness metal tube such as aluminum so as not to damage the surface of the optical transmission body. It has been known. However, high brightness metal tubes are not stable over time due to heat shrinkage, have poor vibration resistance and impact resistance, and furthermore, there is a risk of damage to the optical transmission body itself due to the risk of locally increasing contact pressure. be. For this reason, a structure is sometimes adopted in which silicone resin, which is commonly used, is interposed between the optical transmission body and the high brightness metal tube, but although it has good heat resistance, light resistance, and elasticity, There is a lot of light leakage from the contact part with the body,
There was a problem in that the loss of incident light increased, resulting in poor efficiency.

After contacting the linear light emitting slit surface of the body storage case, both ends of the light transmitting body are coated with the light-resistant light-transmitting elastic member by a fixing device from the side facing the linear light emitting slit surface. An optical transmission body fixing structure characterized in that the optical transmission body is fixed in an optical transmission body storage case by pressing the light transmission body against a linear light emitting slit surface.
