【摘要】：测量不同色温LED背光屏的光谱分布,根据相关原始数据对多个函数表达式进行高质量拟合。通过MATLAB研究了照度因子、蓝光危害因子和节律因子随色温的变化。在可见光范围,对不同色温LED背光屏的蓝光占比进行计算。结果表明:照度因子随年龄和色温增大而减小;蓝光危害因子和节律因子均随色温升高而增大,随年龄增大而减小;当色温为1200K时,LED背光屏蓝光占比与烛光蓝光占比的比值为0.783,6500K时为10.294。青年人受LED背光屏的蓝光危害和非视觉生物效应影响相对较大,在使用时应尽量调低色温。该研究为LED背光屏的个性化设计及色温调节提供了理论参考。
[Abstract]:The spectral distribution of LED backlight screen with different color temperatures was measured, and several functional expressions were fitted with high quality according to the original data. The variation of illumination factor, blue light hazard factor and rhythm factor with color temperature was studied by MATLAB. In the visible range, the blue light ratio of LED backlight screen with different color temperature is calculated. The results showed that the illuminance factor decreased with the increase of age and color temperature, the blue light hazard factor and rhythm factor increased with the increase of color temperature, and decreased with the increase of age. When the color temperature is 1200K, the ratio of blue light to candlelight blue light is 0.783t / 6500K, which is 10.294 when the color temperature is 1200K. Young people are greatly affected by the blue light and non-visual biological effects of LED backlight screen, so the color temperature should be lowered as far as possible. The research provides a theoretical reference for the personalized design and color temperature adjustment of LED backlight screen.
