摘　　要：建筑立面动态景观照明的照明亮度、光色和动态变化速度为照明设计的三个最重要物理参数。本文通过实验的方法找出了不同实验亮度、光色与占空频率的"好评率",并利用对数正态分布函数对其进行数学拟合,从而得到了不同亮度与光色组合情况下实验最佳占空频率和占空频率可接受范围,此外,还利用数学的插值计算法得出各亮度等级与波长组合下所对应的最佳占空频率,并推测出不同亮度情况下,最佳占空频率随波长的变化呈不对称的"燕翅型"分布,照明亮度、光色和动态变化速度三者之间的量化研究结果,为动态照明的设计提供了客观的理论支持,具有重大的参考与指导意义。The three important physical parameters of fa？ ade dynamic lighting are lighting brightness,light color and dynamic change speed.This paper through experiments finds out the ＂positive feedback＂of different brightness,light color and duty frequency.Lognormal distribution function was used to perform mathematical fitting on the results,to obtain the optimum duty cycle frequency and its acceptable range for brightness and color combinations.In addition,the interpolation method was also used to get the optimal duty cycle corresponding to brightness level and wavelength combinations.Under different brightness,the optimal duty varies with the wavelength presenting an asymmetric ＂Swallow Wing Type＂distribution.The quantitative research results of lighting brightness,light color and dynamic change speed provide theory support for dynamic lighting design.
