摘　　要：根据现有中间视觉实用模型并结合测量的实验数据,推导了不同色温LED光源在中间视觉下的照度修正系数。通过修正系数可以更简单准确地对现有照度计测量的照度值进行修正,并计算得出中间视觉下的等效照度。计算结果表明,高色温LED光源更适用于道路照明,并可为适用于中间视觉环境下的照度计的研究提供了理论依据,使其更加符合中间视觉状态下人眼的光特性。According to the practical mesopic model and the existing experimental data,one kind of modified coefficient for different color temperature LED sources under mesopic light level is studied.The coefficient can be used easily to calculate the mesopic equivalent illumination with the results measured for different color temperature light sources under mesopic light level.The results show that higher color temperature LED sources can present better visual performance.Moreover,the results provide the basis for further studies on the illuminometer,which make the illuminometer much more suitable for mesopic vision.
