Abstract
Official abstract text for this publication.
An electrical device, particularly having at least one lighting system having light emitting diodes, such as a television having LED backlighting ( 57 ), which has a stand-by mode (ZPM) with very low power consumption in which only one control unit ( 3 ) is supplied with power via a capacitive voltage divider. For this purpose, alongside parts of the power supply unit ( 2 ), the interference suppression capacitor ( 6 ) is also switched off.
First claim
Opening claim text (preview).
The invention claimed is: 1. An electrical device comprising a power supply unit ( 2 ) that has a voltage converter ( 8 ) and an interference suppression capacitor circuit ( 96 ) made up of at least one interference suppression capacitor ( 6 , 60 ), and having a control unit ( 3 ) disposed on a primary side that has its own power supply circuit ( 10 ) directly connected to a mains voltage ( 7 ) and that can be controlled using an external signal ( 11 ), the electrical device ( 1 )…
