| Zusammenfassung: | The device (1) has a measurement circuit (8) i.e. analog/digital converter, with a single measurement output to provide electrical values representative of two characteristic parameters of an LED assembly. The circuit includes two circuit configurations that provide measurement outputs with values representative of the characteristic parameters, respectively. A switching unit e.g. MOSFET transistor (5) and transistor (15), switches between the circuit configurations of the circuit. A triggering unit (10) periodically triggers measurement of one of the characteristic parameters. An independent claim is also included for a method for controlling the electrical supply of one assembly of a LED. |
