摘要

本研究係以四種不同色溫之發光二極體（Light-Emitting Diode, LED）輔以博物館常用之低紫外線螢光燈管（NU），透過燈具光學性質分析，及利用書畫用紙進行光照劣化試驗，評估燈具合適性之參考。試驗結果得知，較低色溫之LED通常具較低藍光比例與損害因數，對大部分材料造成之色差值影響較小；且LED燈具以較低色溫者演色指數為佳，符合博物館、美術館等展場之需求，可作為展示燈具之參考。

The main aim of this study presented in this paper was to evaluate museum lighting sources causing color degradation on different materials. Painting and calligraphy paper were exposed to four types of white LED lamps with different correlated color temperatures (CCTs) and NU-fluorescent lamp. The experimental result of light sources measurement shows that a low CCT type LED characterized the lower blue wave band ratio and damage factor. The LED lamps result in lower degradation of materials than the NU-fluorescent lamp. It suggests that the LED lamp with lower CCT is appropriate for the museum lighting.
