PURPOSE:To reduce the energy loss of solar light during transmission thereof and efficiently transmit the solar light, by a method wherein solar light is converged by a light condenser, and is then transmitted by a light-transmitting pipe provided at a light converging part. CONSTITUTION:One end of the light-transmitting pipe 2 utilizing reflection of light is provided at the light-converging part of the light condenser 1 in the direction of the optical axis. The solar light 3 is converged by the condenser 1, and the light 3 thus converged is transmitted to a desired place by the light- transmitting pipe 2. Accordingly, the solar light 3 can be efficiently transmitted, and the energy loss of the light during transmission thereof can be reduced. |
