    The invention relates to a method and a circuit arrangement for the Diromen of a light source (1) according to digital Nimmwerten (Dct) by regulation. In order to ensure that a slow high-resolution dirome is possible, but the control nevertheless takes place quickly, it is proposed that the controller (7) operates digitally, but that the setpoint / actual value comparison in the comparator (13) uses analog signals he follows. For this purpose, the digital dimming values (Dct) are first converted into analogue dimming values (Da) in a D / A converter (11). The analog control deviation (xa) determined by the analog comparator (13) is then converted again by means of an A / D converter (14) into a digital control deviation (xct), so that the digital controller (7) can process it. The analogue actual values (Ia) are amplified before the comparison with the analogue dimming values (Da), and the gain (V) is reduced by a factor when a specific operating state is reached. To compensate for the reduction in DIA conversion, multiplication by this factor is performed.

    Indung relates to a method and a circuit arrangement for directing a lamp (1) according to digital dimming values (Dd) by regulation. In order to ensure that a slow direction with high resolution is possible, but the control is nevertheless carried out quickly, it is proposed that the controller (7) works digitally, but that the setpoint / actual value comparison in the comparator (13) with analog signals he follows. For this purpose, the digital dimming values (Dd) are first converted into analog dimming values (Da) in a D / A converter (11). The analog control deviation (xa) determined by the analog operating comparator (13) is then converted again into a digital control deviation (xd) by means of an A / D converter (14), so that the digital controller (7) can process it. The analog actual values (Ia) are amplified before the comparison with the analog dimming values (Da), and the degree of amplification (V) is reduced by a factor when a certain operating state is reached. To compensate for the reduction in D / A conversion, multiplication by this factor is carried out.
