碩士 === 國立臺灣科技大學 === 電機工程系 === 99 === As a newer energy-saving lighting source, LED is now used to road and tunnel lighting gradually due to its evidently energy-saving property and meeting the requirement of national energy-saving and carbon reduction policy.There are many practical factors should be considered during tunnel lighting design, such as luminance and uniformity of the pavement, running expenditures of tunnel lighting and maintenance. The thesis focused on the traffic safety and high lighting quality of the tunnel lighting. Four tunnel lighting schemes, in different luminous distribution properties and mounting spaces, were proposed to simulate and plan the better and energy saving tunnel lighting through a commercial lighting design software, DIALux. The relative lighting parameters are evaluated via an effective performance evaluation methodology for searching the most reasonable and economical consideration. Furthermore, the benefits of dimming control for LED lamps had been studied both from initial investment and energy savings concern. Finally, the proposed tunnel lighting scheme is compared quantitatively with Hsuehshan Tunnel, Taiwan to verify and confirm suitability and practical reasons of applying LED light source to tunnel lighting. The results show the valuable and feasibility of using LED in tunnel lighting.
