The second light pipe 134 connected to the other side and rotatably connected to the reflector support 140 at a predetermined angle, and the third light pipe 136 connected to the lower end of the reflector support 140 at a predetermined angle. Consists of

The first light pipe 132 is a passage vertically connected to the periphery of the rear hole 104 of the reflector 101, and is a section in which high-concentration solar light incident through the hole 104 is incident in parallel. The first light transmitting tube 132 is coupled in a structure in which relative rotation is impossible with respect to the reflector 101.

The second light transmitting tube 134 is a passage connecting the first light transmitting tube 132 and the reflector support 140, an inner tube 134a connected to the first transmitting tube 132, and the inner tube Has a multi-stage structure consisting of an outer tube (134b) that partially receives (134a) and is connected to the reflector support (140).
