| 摘要 |
The invention relates to a method for reading information from an LED module (2), said method comprising the following steps: - electrically isolated transmission (21) of an electrical parameter to a circuit (6) by an evaluation unit (24) on the secondary side of a transmitter, said circuit (6) being assigned to the LED module (2); and - preferably indirect acquisition of an electrical parameter of the circuit (6) or the variation thereof over time on the basis of a parameter acquired on the primary side of the transmitter (21), the electrical parameter of the circuit preferably being the current through the circuit or the value of the resistance or impedance of the circuit. |
