Abstract
Presently, energy conservation and carbon dioxide emission reduction have become increasingly
important because of global warming. Using solar energy, which is considered as one of the most important
renewable energy sources, does not only decrease the consumption of fossil fuels, but also slows down the pace
of global warming. For indoor illumination, our team has developed a technique called "Natural Light
Illumination." Instead of using solar cells, our system directly guides sunlight into the interior of a
structure. However, the efficiency of the light-collecting module is still low. To address this problem, we
propose a new light-collecting module based on a prism array structure with high efficiency. We use optical
simulation tools to design and simulate the efficiency of the module, which is found to be 57%. This value is
higher than that of the original concentrator (i.e., 11%).
