In response to CIE′s recent call that lighting should consider both visual and non-visual effects of light,the relat ionship between visual and non-visual parameters was sought.8LED lighting sour ces with large color temperature range (2678K－7258K),especially ultra-low color temperature LED,were selected to coll ect the spectral distribution data of visible light band of 380nm-800nm.The c hrominance analysis software OSRAM COLOR CALCULATOR and MATLAB were used to calc ulate and analyze the changes of 6visual parameters (Color rendering index,Colo r tolerance,Color quality scale,Color purity,Dominant wavelength,ratio of dark a nd bright S/P) and 4non-visual parameters (Circadian f actor KC,Blue light hazard factor KB,Proportion of 400－500nm blue light,Z value of 1931CIE-XYZ standard chrominance system) with color temperature.The results s how that the 6visual parameters of LED lighting with 8different color temperat ures change with color temperature is relatively complex,so it is inconvenient t o directly find the relationship of 6visual parameters with color temperature.T he four non-visual parameters show a linear increasing relationship with the in crease of color temperature,and the expressions are as follows:KC= 0.11895+6.06953×10－4×T_c、KB=1.62585×10－4+ 1.68239×10－7× T_c、Z=0.01499+5.24009×10－5×T_c 、P=－0.06537+0.00504×T_c.In addition,blue light hazard factors KB and the ratio o f 400－500nm blue light P was expressed as follows:KB= －1.5756×10－4+3.32615×10－5×P,correlation coefficient squared R²=0.979 93.The above conclusions can provide references for the analysis of the change of LED lighting quality and photobiosafety with color temperature,esp ecially for the coordinated development of LED lighting vision and non-vision.
