本論文整合雷射白光光源模組，開發一套矽膠透鏡製程技術，解決全內反射透鏡使用CNC車削、射出成型等方法無法加工尖角的問題，以應用於水下照明。其中，白光光源模組為利用藍光雷射結合黃色螢光粉組成反射式結構。TIR透鏡曲線根據幾何光學理論設計出自由曲面之折射面及反射面，來自光源小角度之光線通過折射面進行準直，大角度之光線通過反射面進行準直，並設計成矩形光型以滿足目標物所需之形狀，提升其照明效率及均勻性。再利用Python及Solidworks建構出模型，並運用光學軟體Tracepro進行模擬和優化，將模擬之最佳參數進行矽膠透鏡製程開發，並另外加工兩種不同反射層之矽膠透鏡進行後續實驗比較。最後針對水下目標物之應用，進行照度、明度(L*)及色差值(ΔE)分析來量化評估矽膠透鏡雷射白光燈具於水下照明與色彩辨識之能力。由實驗結果顯示，在小水槽或大水槽進行之照度及明度(L*)實驗，矽膠透鏡皆優於經過加工反射層後之烤漆及鍍膜，由於透鏡製程之表面粗糙度導致反射層的效率不佳，反而使光線被吸收，導致照明效率下降，分別高出烤漆1.8倍及高出鍍膜2.69倍。本論文所開發之矽膠透鏡能完整製作出尖角，改善傳統加工尖角變形所造成超過9.45%的光學效率損失，證實其建立水下照明燈具之可行性，為水下照明領域提供新型態的材料，以實現20m之長距離照明。

This thesis integrates the laser white light source module and develops a set of silicone lens process technology to solve the problem that the total internal reflection lens cannot be machined with sharp corners by CNC turning, so as to be applied to underwater illumination. Wherein, the white light source module is a reflective structure composed of blue light laser combined with yellow phosphor. The refracting surface and reflective surface of the free-form surface are designed according to the geometrical optics theory for the TIR lens curve. The light from a small angle of the light source is collimated by the refracting surface, and the light from a large angle is collimated by the reflective surface. The designed into a rectangular light shape to meet the desired shape of the target, improve its illumination efficiency and uniformity. Then use Python and Solidworks to build a model and use Tracepro to simulate and optimize. Use the best parameters of the simulation to develop the silicone lens process and machine two different reflective layers of silicone lenses for follow-up experiments and comparisons. The experimental results show that the illuminance and L* experiments conducted in a small tank or a towing tank, the silicone lens is 1.8 times higher than that of painting and 2.69 times higher than that of coating. The silicone lens developed in this thesis can completely produce sharp corners and improve the optical efficiency loss of more than 9.45% caused by the deformation of traditional processing sharp corners. It has confirmed the feasibility of establishing underwater illumination fixtures, providing new types of materials for the underwater illumination field to achieve long-distance illumination of 20m.
