The radiation spectrum of the xenon lamp ranges from ultraviolet to mid-infrared. When the skin is irradiatedbythexenon lamp, the skin temperature will change due to the absorption of the radiation. In order to evaluate whether theskintissue will be damaged when the human body is irradiated with a xenon lamp, it is necessary to obtain the temperaturefield of the skin irradiated by the xenon lamp.In this paper, two methods of numerical calculation and thermal effect test were used to compare and study the instantaneous temperature field of the skin irradiated by a 10Kw xenon lamp.Firstly, the three-layer structure model of human skin tissue was analyzed. Secondly, the heat transfer process of theskinirradiated by the xenon lamp was studied, and the instantaneous temperature field model was established. Thirdly, athermal effect test device was built, and the human skin tissue was replaced by the isolated pigskin tissue. In anindoorenvironment, the experiment of irradiating the pigskin tissue with a xenon lamp was carried out, and the temperatureofseveral positions of the pigskin tissue at different irradiation time was recorded by contact temperature measurement. Finally, using the Heat Transfer in Solids Module in COMSOL Multiphysics 5.5 software, the 3D transient temperaturefield of the skin was solved. The results of experimental test and numerical calculation were compared and analyzed. At the same irradiation time, the numerically calculating temperature value was higher than the experimental test value. Themean value of the absolute error between the numerically calculating temperature value and the experimental test valuewas 6.0°C, and the mean value of the relative error was 14%. The research results provide a scientific basis for thesafeuse of the xenon lamp.
