昼光模拟器的本征光谱分辨灵敏度和光谱优化

Intrinsic Spectrally Resolved Sensitivity and Spectral Optimization of Daylight Simulator

为优化昼光模拟器色度学指标,研究了将同色异谱指数转换为本征光谱分辨灵敏度的计算方法,基于国际照明委员会标准提供的光谱功率分布数据计算每段光谱对色度学指标的影响。模拟发现有6个峰值波长对色度学指标影响较大,进一步对半高宽进行优化,使得此6个峰值波长可模拟出BB级的效果,最后通过优化峰值波长使LED(light emitting diode)昼光模拟器达到AA级。

In order to optimize the colorimetric index of daylight simulator,we studied the calculation method of converting the metamerism index to the intrinsic spectrally resolved sensitivity,and used the CIE(Commission Internationale de L Eclairage)spectral power distribution to calculate the influence of each spectral band.The simulation shows that there are six peak wavelengths,which have great influence on the chromaticity index.The optimization of the full width half maximum with the six peak wavelengths can reach the effect of BB level.The LED(light emitting diode)in AA grade is realized by optimizing the peak wavelength of daylight simulator.
