碩士 === 崑山科技大學 === 機械工程研究所 === 102 === This study is on design of LED for street lighting. Because of energy-saving considerations, the power consumption on design of street lighting is limited to be 36 watts, the installation of light is of 6-meters height, and the minimal average luminance is 15 lux. In this study, Solidworks 3D graphics software is used to design the scale of the street light and the results of the design are imported into TracePro for further optical simulation analysis. This study considers the issues of energy saving and environmental protection. Moreover, the lighting luminance must be higher than 15 lux, with uniformity of less than 3 to achieve good visual quality. Four parameters which dominate the output of the lighting intensity and distribution are investigated for an optimal design. The parameters include the tilt angle of light, light source arrangement, thickness of light reflector, and the size of reflector opening.
