ELECTRONIC H.F. DIMMER FOR HIGH VOLTAGE AND LOW VOLTAGE INCANDESCENT LAMPS

摘要

Electronic H.F. dimmers for high voltage and low voltage incandescent lamps have a very high power factor and extraordinarily low mains current harmonic oscillations. Such appliances for operating low voltage halogen incandescent lamps were usually named until now dimming electronic transformers. The advantage of the invention is that it allows high voltage and low voltage incandescent lamps to be operated at the same time with a H.F. dimmer.
