APPARATUS FOR DETECTING QUANTITY OF SOLAR RADIATION

摘要

PURPOSE:To facilitate detection under a plurality of positional conditions, by a method wherein one terminals of optical fibers are branched to form a plurality of solar-radiation-quantity detection end parts and the other terminals thereof are gathered and connected to a photoelectric converter by an optical connector. CONSTITUTION:One terminals of optical fibers 5 are branched into plural fibers and each fiber is embedded in the wall 2 separating a chamber into inner and outer chambers in a state held by each metal sleeve 4 and the other terminals of the optical fibers are gathered by a covering part 6 and connected to a photoelectric converter 8 through an optical connector 7. By this apparatus, the quantity of solar radiation can be easily detected at a plurality of places.
