Abstract:	本論文提出一種符合照明光形之紅外線 SMD LED 之封裝一次光學設計，此方法透過對目標配光曲線、光源配光曲線與模擬配光曲線的積分運算建構出符合目標配光曲線的一次光學設計。在本論文的研究中，先針對目前市面上各種封裝形式的紅外線 LED進行優劣分析，總結出最理想的封裝形式為SMD-Ceramic封裝形式，接著分析一次光學設計的相關文獻資料，再根據不足的部份提出我們的優化方法，根據優化過後的模擬結果，模擬配光曲線與目標配光曲線的NCC平均達99.84%，接著，我們將LED封裝完成，量測其配光曲線，最後，將實測、模擬與目標配光曲線進行比對，實測與模擬配光曲線的NCC平均達99.64%，實測配光曲線與目標配光曲線的NCC平均達99.72%。 ;In this thesis, we propose a first-order optical design of infrared SMD LED that matches the target intensity distribution. In this design, we design the first-order optical lens that the result intensity distribution can match to target intensity distribution through integrating the target、light source and simulation intensity distribution. First, the study analyzes various commercial infrared LED packages and summed up the most suitable package is SMD package with ceramic substrate. Second, this thesis proposes a method to optimize first-order optical design after we analyze related literature. The simulation result shows the average NCC of intensity distribution between final design of our method and target is 99.84%. Finally, we complete the assembly of infrared SMD LED and measure the intensity distribution. The average NCC of intensity distribution between simulation and measurement is 99.64%. The average NCC of intensity distribution between target and measurement is 99.72%.
