Solar energy is clean and reusable. It preserves the environment and good for human health protection. In addition, sunlight has the greatest rendering index which provides the most natural vision effect. Therefore, tremendous researches are contributed to study daylight applications, including indoor illumination, which is the primary focus of our research.
To approach the objective, a parabolic reflector is applied to collect sunlight. When straight sunlight falls onto a correctly aligned parabolic reflector, it will be reflected back towards a focal point, so we apply a circle hollow light pipe to guide the sunlight. Because the efficiency of the guiding depends on the reflection times of rays, we built mathematical model to calculate the times of reflection in a light pipe and added a wedge structure to improve the efficiency. In order to collect more sunlight, when it’s not straight to fall onto parabolic reflector, we design the appropriate dimension of entering hole to allow the departure.
And then, the weather information of Taiwan is considered to design a compound parabolic concentrator that can collect wide range of the incident sunlight without a sun tracking system. For the maximum efficiency, we define two tilted conditions to evaluate the static concentrator with the total saved energy in visible range.
