<p><P>PROBLEM TO BE SOLVED: To provide a solar lens capable of condensing solar light within a predetermined range using a static lens regardless of position of the sun, to eliminate the requirement that the condensing surface must always directly face the sun according to the position of the moving sun using a sun tracking device for effectively utilizing the solar light, relating to a solar generator of condensing type and a daylighting device for natural illumination. <P>SOLUTION: The solar lens is formed by making a sawtooth rectifier lens, in which an infinite number of rectifier units of isosceles triangles are arrayed, engage with the light emitting surface of a condenser lens whose cross section has inverted trapezoid shape, to condense the solar light from all directions and all altitudes using a static lens. The condenser lens is separated from the rectifier lens with a minute gap. Further, the inclination angles of a slope of the condenser lens and the rectifier lens are set to be such angles that totally reflect maximum incident beam corresponding to the critical refractive angle of a component material or less, thereby condensing the solar light on the light emitting surface. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
