LED色彩照明評價技術之開發

本研究著重在探討新穎LED的評價技術，此技術建立在相關色溫與亮度之間的關係，並使用多頻譜影像技術模擬出在不同相關色溫與照度的條件下RGB LED光源和CIE參考光源照明的色彩再現影像，根據CIE 116的規範做為參考條件，以標準光源D65在照度400 lux的模擬照明影像為基準，與其他光源在不同相關色溫與照度置換之色彩再現影像進行色差計算，找出相關色溫與亮度之間的關係，並以多頻譜影像技術再現照明影像提供視覺上的感受，最後發現在照明上，高相關色溫搭配較低照度光源的模擬照明影像和低相關色溫搭配較高照度光源的模擬照明影像，兩者與標準光源D65在400 lux的模擬照明影像比較後有相近的色差值，且有相同的視覺感受。

In this study, we focus on evaluating lighting source’s relationship between correlated color temperature and brightness.We use multi-spectral imaging technique to simulate 24 color patch’s image with different correlated color temperature and illuminace under RGB LED and CIE standard illuminant. According to CIE 116, we use the simulated image which uses CIE standard illuminant D65 with illuminance at 400 lux as our basis to calculate color difference with other simulated image in order to find the relationship between correlated color temperature and brightness.These simulated images can provide observers with visual perception.Finally, after two simulated images which use high CCT light source with lower illuminance and low CCT light source with higher illuminance light source compare with a simulated image which uses CIE standard illuminant D65 with illuminance at 400 lux,we can find these simulated images have same color difference and visual perception.
