Using the TracePro software environment, the paper presents results of simulating and optimizing the phototherapeutic device lighting systems in treating the wounds and localized infections. It considers a pulsed xenon lamp as the radiation source. The paper determines factors affecting the energy transfer efficiency and the radiation distribution uniformity over the light spot. It indicates that the diffuse reflector shape insignificantly affects characteristics of the irradiation fields. In this regard, the reflector conical and trapezoidal form factors are recommended as optimal being the most technologically advanced in manufacture. The paper shows that the reflector diffuse reflection coefficient significantly affects the irradiation zone energy characteristics and the irradiation uniformity without changing the light spot size. Modern reflective materials for the phototherapeutic devices are considered. Results of irradiation field numerical simulation are compared with the data of direct experimental measurement, and their good agreement is shown. This makes it possible to recommend using the developed methodological approach in designing the photomedicine devices. Based on the known lamp spectral characteristics, the simulation data obtained allow determining the irradiation time for the wound lesions and necessary to achieve the required energy dose during the phototherapeutic procedures.
