摘要

本研究主要是開發以發光二極體為光源的室內照明燈具，透過光學模擬的設計與分析，將反射鏡有效的與發光二極體結合，以達到最佳的照明效果。本論文主要探討的有兩個實際案例，其一為LED崁燈，另一為冷藏櫃LED燈管。LED崁燈使用3瓦的高功率發光二極體配合使用環狀刻面反射罩，經由光學模擬與實際量測結果，可以達到比傳統崁燈更好的照明效果，而且節省了55.6 %的能源使用。藉由熱阻分析與熱傳模擬結果，為此LED崁燈設計的散熱模組，可以很有效的降低發光二極體接面溫度。同樣地，透過光學模擬與實際量測結果，冷藏櫃LED燈管僅需使用48顆0.1瓦的Flux LED，並配合使用橢圓反射鏡，便可達到比傳統螢光燈管更佳的照度分佈效果，以及更好的演色性指數，也減少高達88 %的能源消耗。因此本研究所開發的LED室內照明燈具，具有相當大的潛力足以取代現有燈具。

This research developed the Light-emitting diode (LED) lamps on indoor illumination. With help of optical analysis and simulations, we are able to utilize the reflectors to reach the optimal illumination results. Two case studies are presented: one is recessed LED lamp; the other is LED lightbar. In the first case, it uses 3 W high-power LEDs combined with facetted reflectors in recessed LED lamp. The optical simulation and experimental results demonstrated that our design is more efficient in illumination and saving 55.6 % energy than traditional lamps. In the second case, through the optical simulation and experimental results, the LED lightbar which needs only to uses 48 Flux LEDs of 0.1 W combined with elliptical reflector result in much more uniformity illumination distribution and higher color rendering index (CRI) than the fluorescent lamp. Moreover, it reduce up to 88 % power consumption. Both cases implies great potentials to replace the traditional lamps with the LED lamps developed by our research.
