This article discusses original technical solutions for LED modules that ensure system operation within a wide range of input supply voltages for direct and alternating currents. The effectiveness of the proposed circuit approach is demonstrated using the example of a developed LED lighting device with an electronic LED power system with a driver built using the concept of flyback topology, capable of working with input voltages of both direct (20…300 V) and alternating (36…300 V) currents. The results of experimental studies of electro-optical parameters and characteristics of the manufactured prototypes of the developed lighting systems are presented. It has been shown that the LED modules demonstrate a stable luminous flux and a high luminous efficiency (more than 150 lm/W) at various values and types of supply voltage. The developed lighting systems can be effectively used in domestic and industrial environments, including special-purpose facilities, namely, shelters and warehouses for various purposes, etc. KW - LED lighting systems KW - unstable power supply KW - flyback topology KW - high luminous efficiency ER -
