| 摘要 |
The invention relates to a method for reading out information from an LED module (2), comprising the following steps: - transmitting (21) an electrical parameter relating to a circuit (6) in a galvanically-isolated manner by means of an evaluation unit (24) on the secondary side of a transmitter, said circuit (6) being assigned to the LED module (2), and - preferably indirectly registering an electrical parameter of said circuit (6) or its temporal change based on a parameter registered on the primary side of the transmitter (21), the electrical circuit parameter preferably being the current running through the circuit or the resistance or impedance value of said circuit. |
