| Summary: | 碩士 === 國立臺灣科技大學 === 電子工程系 === 103 === Sunlight is one of the important elements for creatures' survival and growth. Due to the change of lifestyle, people spend about 90 \% of time staying in buildings. In this situation, the artificial indoor illumination gradually replaces the sunlight in human beings' life. This condition may lead to exhaustion, osteoporosis, depression, inability of concentration, and other symptoms if people cannot be exposed to enough sunlight. To solve this problem, this dissertation proposes an Intelligent Natural Light Illumination System. This illumination system can take people's health and environmental protection into account. This system can divide into four parts: Light Collecting, Light Transmitting, Light Emitting, and Auxiliary Lighting. When the sunlight is enough, the lighting system can guide the sunlight into the building for lighting applications. The auxiliary lighting subsystem would control the LED to satisfy the users' demand when the brightness of the environment could not achieve the desired results. After that, it can let the sunlight indoors and improve the quality of human's life at the same time.
