Abstract：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.
