In this paper different light regulation techniques for the LED lamps of distributed lighting system are compared: fluent light regulation, pulse light regulation and step light regulation techniques. The comparison of efficacy and controllability based on theoretical and experimental data is given in this article. It was established that pulse light regulation technique is the most efficient among considered techniques, however it also has significant drawbacks such as stroboscopic effect and flickering. Step light regulation technique has the same controllability parameters as fluent light regulation method, but the efficiency in particular cases may be higher than in case of fluent light regulation.
