[[alternative]]The System Design and Analysis of Energy Saving for Solar Power Street Light

碩士電機工程學系[[abstract]]摘要 近年由於全球經濟持續成長，亞洲等新興國家興起，能源需求也相對大幅度的成長，導致能源價格持續高漲，各種替代能源與節能技術亦紛紛興起。根據工研院統計2005年我國路燈市場規模達1.3百萬盞，其中以水銀燈為主要光源。以目前居高不下的能源價格、能源缺乏等因素，若能有效的結合再生能源與高效率之照明設備，發展太陽光電能街燈，對於節能、減碳必有相當之貢獻。 因此本文以太陽光電能街燈為主題探討再生能源用於照明電力需要效能評估與分析，並以HID(High Intensity Discharge Lamps)燈及LED(Light Emitting Diode)燈兩種方式做為街燈照明設備。考慮陰雨天數電力儲存及維持街燈持續照明特性等需求，當電力充足時由HID燈提供照明，電力不足時則改由LED燈照明，除了省電之外又能達到街燈持續供電的目的。 關鍵字：太陽光電能、LED、HID[[abstract]]ABSTRACT The demand of energy is greatly increased in recent years because of the growth of global economy. The price of energy is also increased in these developing Asian countries. Several kinds of alternating energy are therefore investigated. According to Industrial Technology Research Institute, the street light market supplied 1,300,000 in quantity and most of them are mercury vapor lamp. Since the high price and shortage for the energy are important factors, the combination of renewable energy and high-efficient light equipments are considered. The development of solar-powered street light will have significant contribution to energy saving and reduction for carbon reduction. This research investigates and analyzes efficiency of renewable energy powered street light application. Both High Intensity Discharge Lamps (HID) and Light Emitting Diode (LED) are used for street light. Electrical power storage in rainy days and street light maintenance are considered. HID lamp will be used if the electrical power is sufficient; LED will be used once the electrical power is insufficient. The energy will be saved and street light can continually operated.
