请参阅图 6所示， 揭示出本发明第三款实施例的剖示图， 说明其于上述第 一款实施例相异之处在于， 省略上述辅助镜 5 , 该太阳能电池芯片 3位于该透镜 6中央底面， 而邻近该窗口 12 , 且太阳能电池芯片 3位于该反射镜 2的弧凹状 反光面 21中央上方的聚光区 13内， 该反射镜 2的反射面积大于该太阳能电池 芯片 3接收太阳热辐射能的面积； 如此， 当太阳光照射该壳体 1顶面时， 太阳 光线 7能够通过透镜 6照射反射镜 2的弧凹状反光面 21 , 且反射镜 2经由弧凹 状反光面 21反射所述太阳光线 7照射该太阳能电池芯片 3 , 致使太阳能电池芯 片 3发电， 其余构件组成及实施方式等同于上述第一款实施例。
以上说明对本发明而言只是说明性的， 而非限制性的， 本领域普通技术人员 理解， 在不脱离权利要求所限定的精神和范围的情况下， 可作出许多修改、 变化 或等效， 但都将落入本发明的保护范围之内。
