本文主要目的是研究利用田口方法和TracePro光學模擬軟體，來做為對最近非常熱門的無眩光LED T-Bar燈之最佳化設計與分析，並以「燈杯取代原有的Holder與LENS來降低成本、且利用AR coating的技術來改善燈燈具光學性質」做為設計之目標。 田口方法在穩健參數設計方面的目標，為將建立的設計參數做最佳的組合，本無眩光LED T-Bar燈採用「燈管和燈管間距、燈管管徑粗細、燈管材質、燈杯和燈管間距、燈管兩側切角、AR coating面的選擇」等６個可控制因子，並採用５個水準做參數設計。 以田口方法Ｌ25(56)的直交表設定各項參數，利用tracepro光學模擬軟體進行模擬，並取得２５組模擬結果，再將模擬結果利用直交表計算，使用直交表的設計和變異數的分析，找出製程中主要效應分子為何，以及各因子間的交互關係對回應值的最佳化，有效減少模擬次數，將原本６因子５水準需做１５６２５次模擬簡化為２５次，讓設計者可以在較短的時間內得到較佳的設計參數。 原有Holder加LENS之設計，經TracePro模擬得燈具有效效率為37.78％；經燈杯改善設計和田口方法計算後，最佳設計參數狀況之燈具有效效率為50.7125%，提升1.3423倍（提升34.23％）。 The main purpose of this paper is to examine the application of Taguchi method and program TracePro optical simulation software, to do for the very popular recently Glareless LED T-Bar lighting optimization design and analysis, and "using lamp cup to replace the Holder with LENS to reduce costs, and the using of AR coating technology to improve the optical properties of light lamps for the design goal. Taguchi method will be establish the best combination of parameters, using with “tube and tube spacing, tube diameter and thickness, tube material, light cup and lamp spacing, tube cutting angle on both sides, AR coating surface of choice” such as six factors can be controlled and used to do five standard design parameters. By using the Taguchi method orthogonal arrays, tableＬ25(56), to set the parameters. We simulated in TracePro, and obtained 25 sets of simulation results, and calculate the results to identify the main effects of the process elements. Then we got the best response between the various factors. Taguchi method can be effectively reduce simulation times to 25, the 6 factors and the 5 levels of each factor to be done the simulation to 15625 times. The designers can get better design parameters in a short time. The design of the original Holder + LENS by TracePro simulation was 37.78% effective efficiency of the lamp. The lamp cup to improve the design and Taguchi method of experimental design, the best conditions of lighting design parameters has 50.7125% effective efficiency of the lamp and enhance 1.3423 times (34.23 % raise).
