Modern artificial lighting systems are based mainly on the basis of light-emitting diodes (LEDs), flowing current through which (and therefore - and the level of illumination of the object) is stabilized or regulated in accordance with the environment via an electronic ballast, which is a pulse voltage converter covered feedback output current. Changes in the ambient light requires quick and accurate illumination system and the formation reaction of the LED current, which will provide the best illumination for practicing errors. This article is devoted to development of the structure, functional circuitry and software prototype of the complex to be used for research of intelligent LED driver control algorithms and analysis of dynamic processes in the closed automatic control system containing the inner current and external illumination loop.

Key words:

light emitting diode (LED), electronic ballast, pulse converter, pulse-width modulation (PWM), automatic control system
