| Summary: | 碩士 === 臺北城市科技大學 === 機電整合研究所 === 101 === This study is to improve the existing energy-efficient lighting with LED (Light emitting diode) lights as a core goal to develop a controllable energy-saving lamps. The first generation developed product is using infrared sensors to detect the signal from surrounding. If it senses someone or vehicle which is moving, the light will automatically turn on in full brightness. If it senses no target, it will switch to the half-bright. So that the lamps have different output brightness, and really save the energy as well as to extend the life of the lamps.
The feature of second generation is using microwave sensors to detect parking lots with vehicles or not, then it can control the vehicles in and out to upgrade the efficiency of parking. The third generation system develops optical sensing dimming module to automatically detect the light from surrounding, when the light sensing dimming module detects ambient brightness, the controllable energy-saving lamps will automatically reduce the brightness to save energy consumption.
