PURPOSE:To utilize a device as an illuminating light source in every place, by using a passive reflector of a polyhedral, polygonal and conical shape, and equally branching and transferring sunlight. CONSTITUTION:The sunlight of high density, focused by a condensing lens is cooled by making them pass through a cylindrical pipe (a pipe having a reflecting member on the inside surface) through which water is fed and discharged and after that, are led to a master glass fiber 11. The sunlight 17 of high density for tansferring this master glass fiber 11 is branched to a lot of branching and transferring glass fibers 16 by a passive reflector 21 of a polyhedral, polygonal and conical shape, having a lot of edge line 20 and reflecting materials 19. Also, the reflecting material is provided on the surface except penetration parts 16 of the side of a case 29, as well, the sunlight is branched efficiently and equally. |
