過去在傳統LED光源模型的建立上，並未掌握真實光源之空間色彩特性。本論文提出以高光譜影像儀所獲得的高光譜影像，並結合角測儀所獲得的場型數據，建立出具有空間色彩分佈資訊的光色光源模型。
本研究將三顆不同封裝形式的白光LED進行完整的空間場型分步分析與空間色彩分析，並依據其光源面積大小以理論推算其遠場位置來確認量測結果的正確性。並將量測結果轉換為角度相關色溫差值，獲得了具有穩定趨勢的空間色偏變化曲線。本研究三個樣本所建立出的模型，其空間強度分佈模擬結果與量測結果間之相關係數高於0.995；其空間色彩分佈與量測結果之間的相關係數皆高於0.95；而三個樣本以角度相關色溫差值定義的空間色彩分佈模擬結果與量測結果之間的最大差值分別為405K、220K與2497K，其中Case 3模型的模擬結果雖差值較高，但因為其平均色溫較高，故屬可接受範圍。而在建模的過程較傳統更加簡易，節省了大量的建模時間
最後我們將三樣本中的Case 1使用光源影像角測儀(SIG-400)進行近場量測，並將其產生之光源檔進行模擬比較，其遠場位置與理論推算及量測結果並不符合，而空間色彩分佈於10mm~20mm與量測也有顯著差異，角度相關色溫差值最大差值高達3945K。
與之相較本論文所提出之以高光譜影像建立的Case 1光源光色模型，成功的在不論空間能量分佈與空間色彩分佈皆能表現出隨距離維度的變化趨勢，遠場位置與理論計算完全一致，角度相關色溫差值之變化高度符合，而最重要的是建模過程較為簡易且本論文模型具有光線數、場型分佈與表面分佈的可調整之特性。

The color spatial distribution (CSD) of LED light source was studied in recent years. However, the traditional modeling method of LED did not include the information of CSD. According to this issue, we propose a new method by measuring hyperspectral image and far-field radiation pattern to establish chromatic source model (CSM) which including the properties of intensity and color distribution for LED light source.
In this study, we analyzed three types of white light LED by measuring mid-field measurement and the definition of angular correlated color temperature deviation (ACCTD). These analyzing results were used to verifying the CSM. According, the normalized cross correlation (NCC) between measurement and simulation of intensity distribution and color distribution are all higher than 0.995 and 0.95, respectively. In order to obtain the more accuracy CSM, we further compare the ACCTD of measurement and simulation through mid-field. The differences of ACCTD between measurement and simulation are 405K, 220K, and 2497K, respectively. The ACCTD of Case 3 is acceptable because the average CCT of Case 3 is up to 24767K.
Furthermore, we compared CSM of Case 1 with the radiant source model of Case 1, which established by using the SIG-400 (Source Imaging Goniometer®, Gen. 4). According the simulate process, there is a huge difference between the result of the SIG model and mid-field measurement. The differences of ACCTD between SIG model and mid-field measurement is 3945K, higher than 405K of our model.
In conclusion, this new modeling method of CSM is much easier, faster and more accurate in both intensity and color spatial distribution than traditional method.
