Data confidence 70 medium
How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

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.
