Abstract
A method is provided for operating a control and/or regulating system for a light emitting diode field. At least two first outputs are provided at which control signals for controlling controllable switch elements of the light emitting diode field are tapped. A second output is provided at which control and/or regulating signals for controlling and/or regulating a controllable and/or regulatable power source is tapped. The voltage drop across the light emitting diode field is measured by the first voltage sensor, and when the control and/or regulating signal of the control and/or regulating system falls below a designated voltage value, the controllable and/or regulatable power source is switched off. A constant sensor signal is present at the at least one measuring signal input, and the sensor signal is larger than the designated voltage value.
