The Method of Indirect Assessment of the Quality of Energy Characteristics

Based on research carried out by various enterprises and independent scientists, it has been established that the use of LED technologies in lighting systems – both inside residential and non-residential buildings, as well as in street lighting systems – significantly increases energy efficiency and provides economic benefits. The main purpose of the study is to develop a method for indirectly assessing the quality of energy characteristics during the operation of electric lighting systems to improve their technical and economic performance. In the course of the work, new theoretical and experimental data were obtained, mathematical dependencies were derived describing the ratio of electric and light power, taking into account the parameters of lighting devices and power sources. Graphs were also constructed demonstrating the theoretical dependence of illumination on the electrical characteristics of the power supply, and the relationship between thermal engineering indicators and the quality of the luminous flux was revealed. In the course of experimental studies conducted using laboratory samples of the system, radiation characteristics were obtained and numerical parameters of the optimal operating range of the LED device were determined. For this purpose, numerical computer modeling was used, which makes it possible to analyze changes in the physical processes occurring during the operation of LED lighting systems. The difference between the best and worst results was 9.91%. A unique method of indirect assessment of the quality of energy characteristics during the operation of electric lighting systems has been developed, aimed at improving their technical and economic efficiency.
