PROBLEM TO BE SOLVED: To provide a fixing-type sunlight collector which can collect light received inside into its end parts with high efficiency. SOLUTION: Both the front surface and rear surface of a light guide plate 10 which is made of transparent medium are curved continuously. Solar cell attachment parts are provided on both the left and right end parts of the light guide plate 10, and solar cells 12 are attached to those parts. Solar light 14 incident into the lightguide plate 10 through the front surface reaches the rear surface of the light guide plate 10 and is reflected by a mirror 16, provided on the rear surface and is returned to the front surface again. The sunlight 14 which returns to the front surface is totally reflected by the front surface. The sunlight is transmitted to the solar cell attachment part provided on the end parts while repeating the reflections and total reflections, and enters the solar cells 12. |
