PURPOSE:To prevent heat from being lowered during transmission and to increase the heat exchange efficiency, by leading the light collected by a light collecting to a heater via optical fibers and a rotating paraboloidal reflective plate so as to heat a heating medium circulating through a heat exchanger for accumulating heat. CONSTITUTION:Sunlight converges to the focal point of a transparent body 20, is converted to a high density light flux in a converter 4, and is released via the optical fibers 3 and transmitting optical fibers 18 from a light releasing terminal apparatus 10 toward the rotating paraboloidal reflective plate 8. Then this light flux is reflected by the reflective plate 8, enters the heater 9 located at the focal point, and heats the heating medium that is circulating through the heat exchanger 21 of the heat accumulating tank 20 and a heating coil (not shown) of the heater 9 so that the heat of the light flux is lowered. The heating medium heats water in the heat accumulating tank 20 through the heat exchanger 21. According to this arrangement, the loss of the heat during transmission can be lowered and the heat exchange efficiency can be increased. |
