Özet:

In the work traditional and innovative methods for constant current LED drivers have been studied. The low-cost solutions for energy effective low lighting flicker current regulation have been proposed. The advantage is due to fact that auxiliary switch-mode regulator converts only small part of output power. The proposed solution can be used in LED drivers to reduce pulsations of the light flux, as well as in driverless AC LED modules to monitor LED currents and/for power correction.
