摘　　要：为了得到不同光源色温的辐射谱,提出了基于颜色玻璃和镀膜相结合的方法进行色温变换。以3000 K色温的卤素灯作为标准光源,将其变换成4800 K标准黑体辐射色温,根据目标色温透辐射光谱,选定QB11作为基底,为了进一步修正辐射谱线,选择在QB11基底上镀制光学薄膜。使用Essential Macleod薄膜设计软件设计了以TiO_(2)和SiO_(2)组合的5层膜系,并进行了优化,最终得到膜层厚度为353 nm。实验结果表明,通过颜色玻璃和光学薄膜相结合的方法可有效将标准卤素灯的3000 K色温变换成标准黑体辐射4800 K色温,光谱偏离度质量指数为3.67%。最终的光谱偏离质量指数表明,通过上述方法进行色温变换效果良好。In order to obtain the radiation spectrum of different light source color temperatures,a method based on the combination of colored glass and coating for color temperature conversion was proposed.The halogen lamp with 3000 K color temperature was used as the standard light source and transformed it into 4800 K standard blackbody radiation color temperature.According to the target color temperature transmittance spectrum curve,QB11 was selected as the substrate.In order to further modified the radiation spectrum,the optical film is coated on QB11 substrate.A 5-layer film system composed of TiO_(2) and SiO_(2) was designed by using Essential Macleod film design software.After optimization,the film thickness was 353 nm.The experimental results show that,the 3000 K color temperature of standard halogen lamp can be effectively transformed into 4800 K color temperature of standard blackbody radiation by the combination of color glass and optical film.The spectral deviation quality index was 3.67%.From the final spectral deviation quality index,the color temperature transformation method is effective through above method.
