Abstract: The present invention relates to a device for adjusting the luminous flux of a lamp, which, in one embodiment, comprises a conversion unit for converting a main voltage into a supply voltage to be applied to one or more lamp or light elements. The device also comprises a microcontroller which controls the conversion unit in accordance with a luminous flux adjustment program which may be based on current date and time. The device also includes a receiver (for example, a GPS receiver) to receive a broadcast signal carrying date and time information employed by controller when executing the luminous flux adjustment program or for updating a clock/calendar module. The present invention also relates to a system incorporating such a device as well as to a related method for adjusting the luminous flux of a lamp.

Abstract: A centralized device for supply voltage control of a load with power factor correction condensers for lighting engineering applications has an array converter for obtaining a portion of power, with a plurality of switches located between the network sinusoidal supply and the load. The centralized device has controlling and regulating means for managing both the activation and deactivation states of the switches of the array converter so as to avoid sudden voltage changes across the load and provide for control of the load voltage.
