本論文奠基於孫慶成教授所領導之固態照明實驗室所建立之螢光粉光學模型，利用紅綠雙螢光粉為材料，進行其混粉光學模型之建立與分析。此等效螢光粉光學模型可用來評估一白光 LED 在各特定螢光粉配方下之封裝效率，以及色彩於空間上之分布。藉由模型的開發，成功的利用模擬與實驗驗證，比較混粉及分層之螢光粉配置方式下，空間色偏與封裝效率及演色性之差異，突破文獻中僅能以實驗進行探討之缺陷。在高演色性的光源應用當中，封裝方式有相當多種，因此如何有效由光學模型來進行效率及色彩部分的分析相當重要。藉由實驗進行分析及優化，以發展出高效率且高演色性之封裝型式。最後實際應用至燈具當中進行光學特性之評估與分析以提升其光色品質。;In this thesis, on the basis of the phosphor optical models developed in the solid-state lighting laboratory whose supervisor is Dr. Ching-Cherng Sun, green and red phosphor mixture optical model has been well established. Under some specific green to red phosphor doping proportions, this model can be utilized to simulate the chromatic properties, spatial CCT distributions, and packaging efficiency. On the benefits of applying the phosphor optical model, the confusion about mixture or layer phosphor configuration can perform better could be solved. The comparison and analysis of these phosphor configurations can be made not only in experiment but also in simulation to discuss in more details. There are several types of packaging structures in high color quality applications. Consequently, the importance of phosphor optical model cannot be overestimated. With the help of experimental analysis and optimized in simulation, a packaging structure with high color quality and high efficiency has been approved. Finally, this light source with high performance is utilized in the luminaire to improve the color and energy saving properties.
