    • A refraction method and a compound lens is disclosed for concentrating solar beam in a non-imaging manner for its heat to be harvested and utilized, for example, for generating electricity with thermo-electric or thermocouple circuit when its hot junction is heated. Solar beam (SI), which may be collected over a wide span of the sun's movement without need for tracking, is first refracted with a first positive refractory element which may preferably be an asperical biconvex lens (11). The exiting, i.e. second solar beam (S2), at a still convergent angle is then refracted by a second negative refractory element which may preferably be a biconcave lens (12). The exiting, i.e. third solar beam (S3), converges upon a third positive refractory element, preferably another aspherical biconvex lens (13), which concentrates the exiting solar beam (S4) onto the predetermined heat collection surface area (120). The sum of all the curvature surfaces of the compound lens times the indices of refraction is about zero such that the field of focus is flat. Preferably, the sum of refractive powers of the first and third aspherical biconvex lenses is substantially counter-balanced by the refractive power of the second biconcave lens placed thereinbetween said first and third lenses.
    • 公开了一种折射方法和复合透镜,用于以非成像方式集中太阳能射束以获得和利用其热量,例如,当其热连接被加热时用于用热电或热电偶电路发电。 首先用可能优选为无色双凸透镜(11)的第一正耐火材料折射可在太阳运动的宽跨度上收集的太阳能束(SI),而不需要跟踪。 然后,退出的即第二太阳能光束(S2)以仍然会聚的角度被第二负的难熔元件折射,第二负的耐火元件可以优选地是双凹透镜(12)。 离开的即第三太阳能光束(S3)会聚在第三阳极耐火元件上,优选另一个非球面双凸透镜(13),其将出射的太阳能束(S4)集中到预定的集热表面区域(120)上。 复合透镜的所有曲率面的总和乘以折射率约为零,使得焦点的平面。 优选地,第一和第三非球面双凸透镜的折射率的总和通过其中放置在所述第一和第三透镜之间的第二双凹透镜的屈光力实质上反平衡。
