In the case of a circuit arrangement for determining and displaying that a luminous intensity limiting state has been exceeded, in the case of which circuit arrangement a comparator compares a temperature-dependent measurement, which is obtained by taking the logarithm of a photocurrent with a limiting value which can be defined and contains an adjustable temperature dependency, the comparator is connected by means of one input, in a manner known per se, to the output of a logarithmic amplifier, and by means of its other input to the pick-off of a potentiometer. Furthermore, for its part, the potentiometer is connected therein to a temperature-dependent divider circuit, and the output of the comparator acts on a display circuit and/or a processing stage.
