Methodology for calculating and modeling LED lighting device
Introduction. Reducing energy consumption is one of the urgent tasks, taking into account the adoption of Federal Law No. 261 of the Russian Federation. One of the energy-intensive processes is lighting, which constantly requires development in the direction of energy conservation and new electrical technology and the use of the latest scientific achievements. Materials and methods. The main materials used in the work are the results of leading scientists in the field of lighting engineering and their own previous studies of the main technical characteristics of LED lighting installations, taking into account the peculiarities of their influence on the condition of animals (cattle, laying hens and broiler chickens), as well as the results of experimental data on the distribution of illumination, with the exception of the boundaries of the room. The paper uses theoretical methods of scientific cognition: mathematical analysis, analysis, synthesis; as well as empirical methods: observation, experiment and measurement. Results. The rational distribution of parameters is calculated using the developed mathematical objective function, on the basis of which the software is developed. The software is implemented in a programming environment in the graphical language of the C++ standard. The development has the ability to visualize the distribution of illumination, determines the relationship between illumination and uneven illumination, allows you to optimize the design parameters of the lighting device and select the parameters of the lighting device. Discussion. The above theoretical studies are submitted for discussion, which allow choosing the parameters of the lighting device, taking into account ensuring the smallest deviation of maximum illumination and uneven illumination from their initial set values; the parameters of the lamp that can be used in the design and manufacture of a prototype; the proposed design of an LED lamp with improved technical characteristics; as well as the results, the use of which will lead to a reduction in energy consumption and an increase in the efficiency of electric energy use. Conclusion. A method for calculating the parameters was developed and the results of modeling the distribution of illumination were obtained, which make it possible to determine the relationship between illumination and uneven illumination, to optimize and calculate the design parameters of an LED lighting device.
