摘要:
An apparatus for the closed-loop and open-loop control of filament heating for a lamp, in particular for a fluorescent lamp, has a control loop into which a first filament (W1), an operational-parameter detection element (E), a heating controller (H) and a first actuating element (S1) are connected. The heating poser of the first filament (W1) is detected by means of the operational-parameter detection element (E) and, on the basis of this, a manipulated variable (SG) is determined, by means of which this first filament (W1) is subjected to closed-loop control. Furthermore, at least one second filament (W2 to Wn), which is not connected in the control loop, is controlled on the basis of the determined manipulated variable (SG).
