    Abstract:   本文主要目的是研究應用田口實驗計畫法與TracePro光學模擬軟體,來做為對光電產業中LED燈具之設計與分析,並以低成本、高品質為設計目標。   田口實驗計畫法在參數設計方面將建立設計參數的最佳的組合,採用導光管材質、導光管截面形狀、導光管兩側切角、導光管上方切削高度、導光管兩側鏡頭以及導光管上部切削痕跡等6個可控制因子,並採用5個水準做參數設計,以提高照明燈具之輻射照度。   田口實驗計畫法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,以及各因子間交互關係對回應值的最佳化,將可有效減少模擬次數,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。   原本未經田口實驗計畫法優化的LED燈具之設計,經TracePro模擬可得該狀況之輻射照度(Irradiance)為0.41353 W/m2;田口實驗計畫法計算後,預測最佳設計參數狀況之輻射照度為0.80217 W/m2,輻射照度獲得明顯提升。The main purpose of this paper is to examine the application of Taguchi method and program TracePro optical simulation software, to do for the optoelectronics industry in LED lighting design and analysis, and low-cost, high-quality objectives for the design. Taguchi method will be establish the best combination of parameters, the material of the lighting tube, cross-section shape of the lighting tube, cutting angle on both sides of the lighting tube, cutting height above the lighting tube, the type of the lens on both sides of the lighting tube and the type of notch above the lighting tube, 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 original design of lighting tube without optimization by Taguchi method, the situation in TracePro simulated irradiance for 0.41353 W/m2. The design by using Taguchi method had the better irradiance for 0.80217 W/m2 in TracePro into the simulation, the irradiance was improved significantly.
