高均勻度多重反射面LED燈具之最佳化設計
The Optimization Design for High Uniformity multi-reflector LED Luminaire
摘要
由於LED的效率不斷的提升，及其價格與傳統光源漸漸接近，使得各式照明燈具開始改用LED作為光源，然而LED發光源與傳統光源截然不同之光學特性，造就許多產品其實並不符合相關法規，如配光、照度及眩光等等，在傳統上，用來解決燈具均勻度問題的方式多半是於燈具出光面安裝噴砂玻璃或是塑膠擴散板，然而這會造成燈具效率的大幅降低且均勻效果有限，本論文主要著重於燈具之反射面設計，利用CAD軟體建立燈具反射面本體模型，並利用TracePro及DiaLux光學軟體進行各項光學模擬分析，探討各項有關於照明品質問題，由於田口方法能在較短的時間與較少的實驗次數下完成參數的最佳化，因此於設計中搭配田口實驗計劃法，將三組反射面角度、轉折處成型R角以及反射面材質之反射率列為品質因子參數，以田口直交表進行光學模擬實驗，並搭配變異數分析各項參數，達成最佳化設計參數。 本研究以一個較有規則性的燈具設計流程，提升設計的速度及改變傳統非成像光學設計較倚賴個人經驗的設計方法設計燈具，並比較對照組之市售LED燈具，燈具經過最佳化設計後將均勻度提升至86.3%且統一眩光指數對照市售燈具降低了30%以上，最後將反射面模型開模製出成品並進行實際量測值與模擬值比較分析，以驗證此設計方法之可行性，實驗結果顯示，該最佳化反射面平均照度較兩款市售燈具高出21.9%及44.84%，而在均勻度值分別提升了54.71%及30.89%。

Since the efficiency of LED continually upgrading and their prices gradually approach with traditional light sources, makes a variety of luminaires began to use LED as a light source, but the LED optical properties different from conventional light sources, creating many of the products is not consistent with the relevant regulations, such as with beam distribution, illumination and glare, etc.. Traditionally, to solve the problem of uniformity of lighting, the way is installation a frosted glass or plastic diffuser, however, it will cause efficiency significantly reduced and adverse effect of uniformity, this paper focuses on the design of reflector, use CAD software to create initial model of reflector, and use TracePro and DiaLux which is the optical simulation software for analysis the lighting quality problems, as the Taguchi method in a shorter time and less number of experiments to complete parameter optimization, so the design with the Taguchi method, the reflector angle, the bend forming R angle and the reflectivity of reflector material as a parameter to Taguchi orthogonal arrays for optical simulation and analysis of variance with the parameters, optimization of the more influential factor. This research proposes a more rules of lighting design process, improve the speed and change the design of non-imaging optical design than the traditional reliance on personal experience of lighting design methods, and compare the control group of commercially available LED lamps, luminaire optimized design uniformity will be increased to 86.3%, UGR glare compared with the commercially luminaires reduced more than 30% , the final mold to produce the finished product and the actual measured value and simulated value of the comparative analysis, to verify the feasibility of this design method. The results showed that the optimization multi-reflector average illumination higher than the two commercially luminaires of 21.9% and 44.84%, and the uniformity improved 54.71% and 30.89%.
