Abstract: | 白光發光二極體(white LED)被視為下個世代的照明光源。然而傳統上螢光粉型的白光LED,因為封裝方式所造成的能量損失達30%~50%。本論文藉由建構一個一維螢光層模型來探討螢光層中光的吸收與轉換機制,並由適當的實驗回歸出模型中的參數值。利用此模型,我們討論螢光粉型的白光LED中造成能量損失的因素,提出具體的改善方式,並且利用實驗加以佐證。 White-light-emitting diode (white LED) is considered the next generation lightning source. However the conventional package of phosphor-type LED loses 30% to 50% energy. The thesis constructed a 1-dimentional model to describe the absorption and conversion of light propagating in a phosphor layer. Designing an experiment we can regress the coefficients in the model. We observe the energy loss term in the model and can optimize the phosphor-type white LED package. |
