Title: Converging device for solar light
Inventor: MIYAMOTO KEIGO
IPC: G02B6/42
Filed: 1987-09-29
Abstract: PURPOSE:To improve the durability of an optical fiber cable by forming a gap between a light transmissive member installed in front of a light receiving end face of the optical fiber cable and the light receiving end face. CONSTITUTION:A light transmissive member 126 is installed in front of a light receiving end face of an optical fiber cable 100, and between the light transmissive member 126 and the light receiving end face, a gap (d) is formed. In this state, a solar light which has been condensed by a lens passes through the light transmissive member 126, and thereafter, made incident on the light receiving end face of the optical fiber cable 100, and transmitted by the optical fiber cable 100. When a temperature of the optical fiber cable 100 in the vicinity of the light receiving end face rises by this incident light, this heat is radiated from the light receiving end face, or transferred to air in the vicinity of the light receiving end face but absorbed quickly to the light transmissive member 126. In such a way, the radiation characteristic of the light receiving end face of the optical fiber cable is improved, and an excessive temperature rise of the light receiving end face is prevented.
