Correlation Study of ESLs Lamps Visual Comfort and Power Quality Characteristics

The paper is a continuation of previous studies which discussed separately the effects of voltage variations that occur in the electricity distribution network on the power quality parameter and photometric flicker on energy-saving lamps. Many approaches are combined here to investigate the relationship between those two parameters. Given the complexity of lamp driver architectures, this process is expected to become a new testing method in order to determine and predict ESL lamps behavior. Based only on a few simple optical measurements, complete and comprehensive information can be obtained over undocumented lamps features impacting the user comfort.
