Title: ELECTRONIC CIRCUIT MEANS FOR DIMMING A LAMP
Abstract: The invention refers to an electronic circuit means for improving a power factor of a load in response to a dimmer, in particular during dimming of a lamp with a variable phase cut dimmer. The electronic circuit means comprises network, which is connected parallel to the dimmer and the load, including a static part and a dynamic part, wherein the dynamic part is embodied by a network of active and passive components being placed In parallel with the load and restricting the power delivery to the load as the dimmer is progressively advanced.
