必要とするほか、約２．５ Ｋｐと非常に重いもので、
取扱いずらいものである。For example, spotlights used in television studios, theaters, etc. use a light control body as a focusing lens, such as a Fresnel lens or a convex lens. Since this type of light control body reaches a high temperature of about 200° C. due to the heat generated from the lamp disposed inside the lamp body, it is generally made of glass. However, glass is heat resistant,
Although it has excellent mechanical strength, weather resistance, transparency, etc., it has poor light controllability because it has poor moldability of the light control surface, especially the prism. For this reason, when a clear contour of the spot is required, Fresnel lenses cannot be used, and plano-convex lenses that are polished after molding are used, but this requires a polishing process and is approximately 2.5 Kp and very heavy,
It is difficult to handle.

スポットライトなどには使用できないものである。For this reason, it has been proposed to use a heat-resistant synthetic resin, such as polycarbonate, which has relatively good mechanical strength, excellent moldability into prisms, etc., and good light controllability. However, this product has a heat resistance of 150°C.
It can withstand only a moderate temperature (=) and cannot be used for spotlights, etc., which can reach temperatures of about 200 degrees Celsius.

された。In view of the above, it has been proposed to use silicone resin, which has excellent heat resistance and excellent moldability to realize precise light control. However, silicone resin has flexibility and is easily deformed, making it difficult to use it alone as a light control material. For this reason, a light control body has been proposed in which deformation is prevented by bonding a light control member made of silicone resin to a substrate made of glass with an adhesive.

くなるとともにはがれ易くなるなどの不都合がある。However, the adhesive that bonds the light control member made of silicone resin and the substrate made of glass generally has poor heat resistance, and if used in a place where the temperature reaches about 200°C, the adhesive will not adhere properly. There are disadvantages such as yellowing and other deterioration of the agent, resulting in poor transparency and easy peeling.
本発明は上述の事情を考慮してなされたもので、透明度

するものは上述のような実用上の問題がある。Summary of the Invention] Next, the present invention will be explained in detail. A light control body in which a light control member is molded from silicone resin and adhered to a substrate made of glass with an adhesive to prevent deformation has been proposed, and some of the light control members have been put into practical use. However, a light control body constructed by bonding a light control member made of silicone resin and a glass substrate with an adhesive has the above-mentioned practical problems.

透明性が損なわれず、しかも、変形が防止し得るもので
あればシリコーン樹脂を制光体として充分活用できると
の知見に基づいて本発明をなしたものである。However, silicone resin has excellent heat resistance, as well as prism formability, light control properties, and weather resistance, so it is possible to attach glass substrates to components without losing transparency. Moreover, the present invention was made based on the knowledge that silicone resin can be fully utilized as a light control material if it can prevent deformation.

部の周縁に平坦面側に突出して取付は部材の周縁に嵌合
する嵌合部を一体に形成したことを特徴とする。In the present invention, a substrate portion is formed with one light control surface and a flat surface on the other side, and is made of silicone resin, and the substrate portion protrudes from the periphery of the substrate portion toward the flat surface side and is fitted to the periphery of the member. A feature is that the fitting portion is integrally formed.

制光体の交換なども容易となる。According to the present invention (2), the fitting part should be fitted to the periphery of the member when attaching the fitting part to the glass substrate or the part for attaching the light control body of the spotlight. The fitting holding part is integrally formed with the flexible silicone resin substrate, so it can be easily attached to and detached from the member.
It also becomes easier to replace the light control body.

1 is a light control body, and this light control body 1 is made of a silicone resin having transparency, heat resistance, and flexibility. Then, this light control body 1 includes a substrate portion 4 formed with one light control surface 2 and a flat surface 3 on the other side, and a peripheral portion of this substrate portion 4 that protrudes toward the flat surface side, which will be described later. The mounting is made up of the circumference of the member (: a fitting holding part 5 that fits and holds the board part 4.
is formed, for example, in the shape of a disc with a diameter of 200 mm and a thickness of 2 mm, and the light control surface 2 on the negative side is formed as a concentric prism group 6 (therefore, it is formed as a Fresnel lens surface. A fitting holding portion 5 having a U-shaped cross section is integrally formed on the peripheral edge of the substrate portion 4.

らに、透過率の低下が良好に防止することができる。As shown in FIG. 3, the light control body 1 constructed as described above is mounted by fitting the fitting holding part 5 to the periphery of the part 7 by utilizing the flexibility of the transparent glass substrate. I can say a few phrases. In this case, since the light control body 1 and the material 7 made of the glass substrate are integrally joined, the mechanical strength of the light control body is improved and deformation is prevented. In addition, as shown in FIG. 4, the light control body l is installed in the spotlight 8 in a cylindrical shape by fitting the self-supporting part 5 that fits into the member 7' by using its flexibility. It can also be installed. In this case, since the light control body 1 is directly attached to the spotlight 8 on the part 7', the mechanical strength can be improved without requiring a glass substrate, etc., and the number of parts can be reduced. Decrease in transmittance can be effectively prevented.

Since the prism has excellent formability, light control performance can be improved. Further, the light control body 1 has a holding portion 5 fitted to the periphery.
The members 7 and 7'i can be easily fitted and mounted by utilizing their flexibility, making the operation easier and improving the mechanical strength. The weight of the light control body can be reduced.
