摘要
为了使基层质检人员经济快速的评估光源蓝光危害与节律效应, 测量了六种常见人工照明和三种显示器的光谱分布, 结合QB5型钴蓝玻璃片的透射率, 对九种光源透过QB5型钴蓝玻璃片的光谱分布进行计算分析, 研究了光源蓝光危害因子和节律因子与1931 CIE-XYZ色坐标Z值、 透过钴蓝玻璃片的主波长及明视觉光通量的关系; 以人眼对波长及亮度变化的分辨力为依据, 验证了以烛光为参照, 根据人眼透过QB5型钴蓝玻璃片观察到的光源亮度, 对光源蓝光危害与节律效应进行可视化评估的可行性。 结果表明: 九种光源的蓝光危害因子和节律因子均随色坐标Z值、 透过钴蓝玻璃片的主波长及明视觉光通量的增大而增加; 该可视化评估方法可行。 研究方法与结果可为光生物安全评估与相关仪器设备开发提供参考。
Abstract
In order to provide general consumers with a convenient and direct method for evaluating blue light hazard and circadian effect of light source, the spectra distributions of six common artificial illumination and three displays were measured. The spectra distributions of the nine light sources going through QB5 cobalt blue glass were calculated and analyzed, combined with the transmittance of the adopted glass. The relationship between blue light hazard factor, circadian factor, and chromaticity coordinate Z value of 1931 CIE-XYZ was investigated, as well as the relationship between dominant wavelength of the glass and luminous flux through the glass. Based on the resolution of wavelength and brightness variation by human eyes to visible light through the glass, the feasibility of evaluating blue light hazard and circadian effect in visualization way was demonstrated where candlelight was the reference. Results showed that blue light hazard factor and circadian factor of nine light source increase with the increase of the chromaticity coordinate Z value of 1931 CIE-XYZ, the dominant wavelength and the luminous flux through the glass, which verified the feasibility of this method. The research method and the obtained results can provide reference for the evaluation of photobiological safety and the development of related devices.
