| Summary: | 碩士 === 國立高雄應用科技大學 === 電子工程系碩士班 === 101 === Lighting is an indispensable appliance to daily life of human. Therefore, the total average power consumption of every country around the world spending on lighting appliance is very appreciable. International Cooperation Sci-Tech Newsbrief (May 2010) mentions the lighting power consumed 20% rate in world energy usage. The requirement for lighting power will more increase to 80% in 2030, predicted by power experts. The lighting type includes commercial (70%), residential (26%) and street lighting (4%). Recently a lack of energy and rising of environmental awareness, lighting power consumption in the world expects to be reduced at least 38% by new lighting LED with energy saving and environmental concept, and combined with improvement of energy-saving technologies. Energy saving is not to have a negative effect on quality of life due to reducing power usage. However, energy shall be efficiently and appropriately applied.
In this study, provides an efficient energy-saving lighting control system in relation to lighting environment and psychological reaction to achieve comfortable atmosphere and energy saving. The system structure consists of a microprocessor module, sensor module, LED driver modules, and LED lighting device. To achieve the wisdom dimming of the LED lighting device by inputting auto-dimming ideal parameters into the microprocessor module, and using output PWM signal of microprocessor module and sensor module. The actual experiment conclusion, the common lighting in the home between 9:00 and 17:00 after using Dimmer system that can reduce the energy consumption around 60% to 65% than before, and the lighting for business store can reduce energy consumption around 30% to 45% .
In different environmental light and temperature, the system can automatically adjust the illuminance light as expected and color temperature based on various requirement of user. To prevent from much lighting power wasting and unnecessary full power load while power switch on. It can be fully applied in natural light, such as commercial interiors, signs, billboards and public electricity lights, automotive illumination, not only can save a considerable amount of electricity for lighting, but also It can achieve carbon reduction.
