Reducing energy costs during the production of agro-industrial livestock production by maintaining the required lighting parameters is an urgent task. The largest consumption of electricity in farms is by electric lighting. The mass transition to energy-efficient equipment, using control systems in livestock and industrial premises of the agro-industrial complex, leads to increased energy savings and maintenance of optimal microclimate mode. (Research purpose) The research purpose is in developing energy-saving lighting installations, a program for automatic control of the lighting system and assessing the prospects for their use for enterprises of the agro-industrial complex. (Materials and methods) The article presents an overview of developments, scientifically based led lighting devices to maintain the required lighting parameters in livestock and industrial premises of the agro-industrial complex, in order to save electricity. Authors have determined that the technical effect of the proposed lighting installations is in reducing the electrical energy consumed. In one of them by creating a special shape of the light intensity curve, and in the second one by converting thermal energy into electrical energy used for additional power supply of the lamp. (Results and discussion) The article presents the results of research on the development of a program for automatic control of lighting systems for the implementation of energy-saving mode of operation. Authors consider the possibility of maintaining and regulating optimal illumination with the help of programmable controllers. (Conclusions) The analysis of the state and prospects of development of lighting systems showed the possibilities of development of scientifically based led lighting devices, as well as programs for regulating lighting in livestock premises based on programmable controllers. The use of the system will allow achieving optimal parameters of the microclimate, increasing productive and reproductive indicators, and effectively use optical radiation by reducing the consumption of electrical energy by up to 30 percent with the same quality of lighting.
