| 摘要 |
The invention relates to a method for reading out information of an LED module (2), comprising the following steps: transmitting (21) electrical power to a circuit (6) on the secondary side of a transformer in a galvanically isolated manner in such a way there is a defined voltage on the circuit (6), wherein the circuit (6) is associated with the LED module (2), and indirectly sensing an electrical parameter of the circuit (6) or the change thereof over time on the basis of a parameter that is sensed on the primary side of the transformer (21). |
