An overview of existing energy-saving lighting sources for premises was conducted in the paper. The method of measuring the brightness of organic light-emitting structure, which consists of a measuring part, which is carried out on the developed measuring device and a mathematical part of direct calculation of the OLEDs glow brightness was proposed. The measuring was carried out on the basis of the developed structure and proposed method for brightness measurement. Current-voltage and voltage-brightness characteristics of organic light-emitting diode were shown.
A circuit solution to the OLEDs glow brightness automatic control, depending on the room lightning was developed. The electrical schematic diagram in the program environment Proteus was modeled and optimized. The proposed diagram allows optimizing the performance of light-emitting device using the OLEDs and their control system, reducing power consumption. During the optimization, the optimum values for parameters of electrical diagram and microcontroller code table were selected.References
