碩士 === 淡江大學 === 電機工程學系碩士班 === 102 === Energy saving and environment protection issues have drawn people’s attention these days as the global industrial development prospers; the conventional incandescent lamps in recent years have continuously been faded and instead the LED (light emitting diode) lamps have brought in unlimited business opportunities in the illumination industry. Comparing with other illumination technology LED has many unique characteristics and also with its capability to illuminate many different color patterns makes the applications of LED across many fields. It needs to have direct current and low voltage in LED power supply therefore it is not suitable to design and fabricate LED directly on the same power sources as the conventional incandescent and fluorescent lamps. Consequently in the development of LED products it needs to use fixed voltage transformation and to consider proper electronic circuit technology in its product design. In this thesis many color modes of LED products are designed and fabricated; it utilizes one single light apparatus to generate many different color modes of LED lamps and it also solves the heat dissipation problem. The design of control circuit is for fixed voltage circuit and with it to accomplish the requirements of energy saving, small size anal then to produce many specific color patterns of LED lamps.
