OPERATION OF A LAMP WITH AN AUTONOMOUS ENERGY STORE

摘要

An operating device (1) for operating an illuminant (2) is proposed, having: an energy storage unit (3) for storing electrical energy, a charging circuit (4), requiring the supply of a mains voltage (Vin), for charging the energy storage unit (3) during a charging mode of operation, a driver circuit (7), supplied with power by means of the energy storage unit (3) during a storage mode of operation, for operating the illuminant (2), and a control unit (8) for activating the charging mode of operation or the storage mode of operation independently of the state of the mains voltage (Vin), particularly independently of the level of the mains voltage (Vin).

主权项

1. An operating device (1) for operating a light-emitting means (2), comprising:
an energy storage unit (3) for storing electrical energy, a charging circuit (4) to which a mains voltage (Vin) is to be supplied for charging the energy storage unit (3) during a charging operating mode, a driver circuit (7) to which power is supplied by the energy storage unit (3) during a storage operating mode for operating the light-emitting means (2), and a control unit (8) for activating the charging operating mode or the storage operating mode independently of the state of the mains voltage (Vin).
