本論文內容為利用 3D 繪圖軟體及高階光學模擬分析軟體,針對側邊置入式光源之投射式頭燈作光學模擬設計,首先利用 3D 繪圖軟體建構出光源位置與透鏡 Lens 整體外型,再利用橢圓的雙焦點原理將橢圓焦點格別置於光源與成像板上,當中之橢圓尺寸需參考原廠投射式頭燈樣品,以便達到設後續計完成後能與原廠體積相似,而實驗中光學面建構均使用繪圖軟體中線架構編織面來成形,而線架構則是利用橢圓經過單軸向定點比例縮放的效果,將原本聚光的正橢圓發散成理想中的均勻擴散光形,最後將所建構出所有光學元件匯入光學模擬軟體中進行模擬分析,並依所屬規格的車用頭燈法規為基準來利用反覆調整線架構與模擬的方式將光學面設計完成。 此研究不具有複雜的程式設計與理論,單存是利用繪圖軟體本身的功能及搭配基本的光學模擬分析,就能達到現有市場上特殊設計的頭燈需求,甚至實驗中有將原廠樣品使用成像光學鏡頭拍攝後再利用逆向軟體建構出逆向設計的原廠光學面,經過模擬分析所得到之光形並不甚理想,但利用現架構方式建構出之光學面光形則較均勻且光強度也較亮,兩者比較之下能明顯看出此實驗結果不僅能設計出理想光學面,亦能達到強光區域的亮度需求。總結來說本研究所建立之原理結合 3D 繪圖軟體應用,光學模擬,CNC實體製作與配光驗證的具體數據,將能幫助單純只能利用繪圖與模擬軟體的設計者,能針對設計此類型頭燈能夠有效率的作光學調整與光學修改。
This thesis is using 3D graphics software and high-end optical simulation analysis software for the implanted side of the projection light source for optical analog design headlights, the first to use 3D graphics software to construct the light position with Lens LENS overall appearance, reuse oval bifocal principle focus of the ellipse grid will not put the light source and the imaging plate, which need to refer to the original size of the oval projection headlights samples, in order to achieve complete set up with the original total volume similar to the experimental optical surface were constructed using graphics software architecture woven surface to forming midline, while wireframe is to use the elliptical through uniaxial fixed scaling effects, the original condenser is ideal elliptic divergence into uniform diffused light shape, and finally the construct all optical components imported optical simulation software simulation analysis, and follow the specifications of the car headlights belongs regulations as a benchmark to use repeatedly adjust line architecture and simulation approach to optical surface design is completed. This study does not have a complex program design and theory, a single deposit is to use graphics software functionality itself and with basic optical simulation analysis, we can achieve the existing market demand for specially designed headlights, and even experiment with the use of the original sample shots and then use optical imaging software construct reverse reverse design original optical surface, obtained through simulation of light shape is not very satisfactory, but the use of the existing architecture of ways to construct an optical surface shape are more uniform and light intensity also lighter, comparison between experimental results can obviously see that this is not only able to design the ideal optical surface can also fulfill the needs of the brightness of light areas. Summary speaking with the principles established in this study combined with 3D graphics software applications, optical simulation, CNC production and photometric verification entity specific data, will be able to help only use simple graphics and simulation software designers can focus on the design of this type of head lights can be more efficiently for optical adjustment and optical modifications.
