Abstract
An algorithm is developed for calculating the design parameters of a LED lighting device. The method for calculating the main structural parameters is based on one of the optimization methods of mathematical analysis, a genetic algorithm with real coding. The genetic algorithm is a numerical heuristic search method used to solve optimization and modeling problems by sequentially selecting, combining and varying the desired parameters, searching for the global minimum of the function, not deteriorating the solution at each iteration, simplicity of limiting the corridor constraints. To simplify the calculation and minimize the number of calculations, based on the developed algorithm, a software is developed. The developed algorithm and software make it possible to define the parameters of the LED lighting device, providing normalized illumination on a horizontal working surface with minimal energy consumption, to evaluate the distribution of light flux taking into account the configuration and geometry of the LED lighting device. To check the operability of the program, its visualization is presented. The results of calculating a lighting device for illuminating a horizontal working surface (feeder) in the animal husbandry building are presented. When using the proposed device, the uniformity of illumination of the longitudinal horizontal zones of the working surface, which are located between adjacent LED lighting devices, is increased.
