Abstract
We have designed an optical component to collect sunlight for indoor illumination. We use a CPC structure utilizing the edge-ray principle to design the collecting part to gather sunlight at many different angles, without a sun tracking system. The CPC structure was designed with the sun condition in Taipei each season. For the maximum efficiency, we define two conditions to evaluate the static concentrator is total energy saving in the visible range.
