<p><P>PROBLEM TO BE SOLVED: To improve a solar light amplifier in which a tip of a condenser is formed in a wedge shape. <P>SOLUTION: The condenser has one surface forming the wedge shape of a transparent material having a tip with a wedge angle of≤30°as a reflecting surface and the other surface forming the wedge shape as an incident surface for sunlight, and increases the luminous flux density of the sunlight by projecting reflected light reflected by the reflecting surface directly from the incident surface as a projection surface or after totally reflecting the sunlight by the incident surface so that the light is projected at an angle of refraction larger than an angle of incidence when the sunlight is made incident on the incident surface vertically or obliquely to the tip side of the wedge. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
