碩士 === 國立高雄科技大學 === 機械與自動化工程系 === 107 === As archetypal energy-saving products, light-emitting diodes (LEDs) are widely used in various lighting equipment such as medical lighting, indoor lighting, and road lighting equipment because of their excellent light source characteristics, and their use signifies global efforts to achieve environmental protection and energy conservation.

This study primarily focuses on the interior area of high-speed tunnels and employed LEDs as the light source to design special lighting modules. To solve the problem of insufficient illumination and brightness of LED tunnel lighting, lighting efficiency in tunnels should be improved by shortening the distance between lamps in tunnels.
An LED street light module (SmileRay) is used as our basic design architecture. The initial model of the lens is constructed according to the laws of geometric optics by using CREO modeling software, and the optical design simulation function of LightTools was used to design the secondary optical lens and the lightbar light source module; it is also used to modify the lamp mechanism. Next, values for the lens light distribution are input into the DIALux lighting design software to verify the accuracy of the simulation for tunnel illumination specifications, and the lens design is further adjusted on the basis of the result. Finally, the erection mode is optimized.
