碩士 === 國立高雄第一科技大學 === 機械與自動化工程研究所 === 99 === The study is focused on designing LED of street light. The main purpose is satisfied with the new regulation and met with low energy loss of street light. The luminous flux of LED light is lower than high pressure traditional sodium lamp. Therefore the LED light must be arranged to meet luminous flux requirement. But its optic properties will lead to light non-uniformity and light shape is difficult to control. Due to the LED light is the energy-saving, the upper quantities of LED light must be less than 75W to meet the energy-saving requirement. The new LED of street light in design process the secondary optic design, the total quantities of LED light, ray tracing cut out and adjusted unwanted light sources must be considered to meet CNS 15233 and energy-saving requirement. Finally the new LED street light in light utilization is more efficiency than market product in the road field simulation using optic software is done.
