汽车太阳膜的色度与光谱特性分析

通过用带计算机控制的WGS-9型色度测量系统、UV-Vis 8500型双光束紫外-可见分光光度计和WGD-4A型光栅光谱仪定量测量和分析了某品牌汽车太阳膜的色度和光谱特性。测量分析结果表明：低红外透过率和紫外透过率与高可见光透过率是一对矛盾体，在选择太阳膜时只能有所侧重。如要求较高可见光透过的同时要避免过多紫外线照射，那应选择主波长为587.3 nm(浅蓝)或522.1 nm(钻石绿)的太阳膜。如要求较高可见光透过同时要兼顾隔热节能的功能，那么应选用色度主波长为497.3 nm(宝石蓝)或507 nm(翡翠绿)的太阳膜。

Analysis of Chromaticity and Spectral Properties of Car Solar Films

Chromaticity and spectral properties of the ordinary car solar films of a certain brand in the market were qualitatively measured and analyzed with WGS-9 chromaticity analysis system,UV-Vis 8500 double-beam ultraviolet/visible spectrometer and WGD-4A grating spectrometer.The result shows that getting low infrared/ ultraviolet transmissivity and high visible light transmissivity at the same time is impossible,so only one aspect can be fulfilled when we choose solar films.Solar films with main wavelength 587.3 nm(Cambridge blue) and 522.1 nm(diamond green) should be chosen if we want to get high visible light transmissivity and low ultraviolet transmissivity.Solar films with main wavelength 497.3 nm(diamond blue) and 507 nm(emerald green) should be chosen if the authors want to get high visible light transmissivity and heat insulation function.
