Abstract
The application relates to a circuit for operating a light-emitting means, having a half-bridge or full-bridge circuit for providing a supply voltage for the at least one light-emitting means, and a control circuit for the closed-loop control of the operation of the light-emitting means and/or fault identification. A measurement signal which represents the current through the bridge circuit and/or a measurement signal which represents the lamp current and a measurement signal which represents the voltage across the at least one light-emitting means are supplied to the control circuit at the same input.
