摘要: The invention describes a method for the modulation of light intensity fluorescent lamps via supply main by modification form and/or amplitude power provided. An electronic control element, provided as component logical circuit, temporarily blocks current flow after at least every second zero-crossing voltage, dependent upon time voltage. Blocking occurs only during period in which there is no charging downstream direct-current mains circuit. advantage thus obtained that pulses circuit do not influence electric flowing through lamps.
