PURPOSE:To obtain a sunlight condensing device of which its focus can be easily obtained, by using a reflective plate having a spherical face only on one side. CONSTITUTION:A lens plate 2 is arranged at the focal position of the arcuate reflective plate 1 in the axial direction (X-X direction), and a light transmitter 3 is arranged at the focal position of the lens plate 2. The sunlight L converged with the plates 1, 2 is conducted and transmitted to a desired position. When the circumferential side faces of the plate 2 are provided with a reflective mirror or a clad layer the light introduced into the lens plate 2 does not leak. |
