ABSTRACT:
The device includes a circuit for generating signals indicative of a reference current which is variable in steps and, during successive time intervals defined by a clock-signal generator, decreases according to respective predetermined functions as the voltage detected across the lamp increases, these functions corresponding substantially to respective predefined constant values of the power supplied to the lamp, and a differential comparator circuit which compares the values of the reference current generated with the current detected in the lamp and generates an error signal in dependence on the difference between them. The error signal can be used to control the device for supplying the lamp.
