    摘要: 在本論文中,我們將設計一款搭配一維柱狀透鏡陣列(Cylindrical Lens Array, CLA)結構之下打式反射面,以控制最亮點(Emax)的位置,並盡可能縮短最亮點與截止線(cut-off line)之間的距離。在光形設計方面,本研究將能量集中於光形下緣區域,並將初始光形設計為上寬下窄之幾何分布形式;再透過不同參數之一維柱狀透鏡陣列結構進行水平方向延展,使能量經過疊加後,達到將亮點上移至特定高度之目的。
    本論文研究基於孫教授領導的固態照明實驗室的光學設計與封裝技術。我們的目標是設計一款符合德國StVZO 22A TA23法規和聯合國歐洲經濟委員會(UNECE)第113號法規B類標準的白色LED頭燈,該頭燈採用柱狀透鏡陣列。
    在傳統設計流程中,下打式反射面完成設計後,通常需先進行打樣製作,再透過實際量測確認一維柱狀透鏡陣列對光形之影響。然而,本論文於反射面打樣前,先利用投影機投影初始光形,並使光線通過柱狀透鏡陣列,,以量測 CLA 對光形的實際影響,藉此降低研究開發過程中的時間成本與製作成本。;This thesis proposes the design of a low-beam reflector combined with a one-dimensional Cylindrical Lens Array (CLA) to control the position of the maximum illuminance (Emax) while minimizing the distance between Emax and the cut-off line. In the optical design, the energy is concentrated in the lower region of the beam pattern, and the initial light distribution is configured with a trapezoidal distribution featuring a wider upper section and a narrower lower section. By employing one-dimensional cylindrical lens arrays with different divergence angles to expand the light distribution in the horizontal direction, the redistribution of energy shifts the maximum illuminance upward to predetermined positions.
    The optical design presented in this thesis is based on the optical design and packaging technologies developed by Professor Sun′s Solid-State Lighting Laboratory. The objective is to develop a white LED headlamp combined with a cylindrical lens array that complies with the German StVZO §22a No.23 regulation and ECE R113 class B regulation.
    In conventional design procedures, after the design of lower-beam reflector is completed, the procedure is typically fabricated and experimentally evaluated to investigate the influence of the Cylindrical Lens Array on the light pattern. However, before manufacturing the reflector, this study first utilizes a projector to generate the initial light pattern and directs the projected light through the CLA.
    The actual effect of the CLA on the light pattern is then measured experimentally. This approach enables the optical performance of the CLA to be evaluated in advance, thereby reducing both the development time and manufacturing costs associated with the research process.
