<p><P>PROBLEM TO BE SOLVED: To effectively utilize solar energy by controlling the angle and the density of sunlight with a simple device, in utilization of solar energy. <P>SOLUTION: In this sun tracking system, a light duct B9 and a light duct A10, each with an angle to the axis, are individually and rotatably controlled to have the in-coming light side axis of the light duct B9 automatically track the direction of the sun, and light is guided in the ducts by the reflection from inner surfaces of the light duct B9 and the light duct A10 or by the reflection from a reflector 46. Thus, the output light is fixed in a specified direction. A parabolic reflecting structure is employed to retain the parallel state of the light even after the sunlight concentration. <P>COPYRIGHT: (C)2003,JPO</p> |
