【摘要】 目的比较不同色度纸张对荧光灯、白炽灯与自然光等的反射光谱成分,为制订相关卫生标准提供依据。方法深、浅色纸张2组,各采用不同色调纸张7种,测定其在白炽灯、荧光灯、白炽灯+荧光灯、自然光和(457±2)nm蓝光等光照条件下14种纸张的反射系数。结果自然光的反射系数高于白炽灯,深、浅色组平均分别高33.0%和36.3%;自然光的反射系数更高于荧光灯,深、浅色组平均分别高56.2%和41.3%。照射在以反射长波光为主的深橙色纸张(H=14)时,白炽灯的反射系数比荧光灯高88.4%。结论白炽灯和荧光灯之间光谱成分有明显差异,且两者都不能完全模拟自然光。更多还原

【Abstract】 Objective To compare the spectrum constitution among fluorescent lamp(FL),incandescent lamp(IL) and sunlight on different colors of paper,and to provide evidence for the related hygiene standards.Methods Determine reflecting index(RI) on seven sorts of dark and light color paper respectively under 5 light conditions,including IL,FL,IL+FL,SL and(457±2)nm blue light(BL).Results In the dark color paper group,the average RI of SL were 33.0% and 56.2% higher than IL and FL respectively.In the light color paper group(LG),the average RI of SL were 36.3% and 41.3% higher than IL and FL respectively.In long wavelength range(dark orange,H=14),the RI of IL was 88.4% higher than FL.Conclusion There are obvious difference between IL and FL,and both of them can not mimic sunlight totally.更多还原
