The present invention provides a method for predicting a remaining lifetime of an electrical component of an electrical circuit, the electrical circuit being part of a building management device. The method comprises: estimating (S) two or more estimated temperatures of the electrical component by using a trained machine learning model of the electrical component that is trained based on training data. Further, the method comprises: generating (S) a temporal course of temperature of the electrical component based on the two or more estimated temperatures; and computing (S), based on the temporal course of temperature of the electrical component, an indicator for the remaining lifetime of the electrical component. The present invention also provides a method for predicting a remaining lifetime of an electrical circuit being part of a building management device.

Circuit for the operation of at least one LED

A circuit for the power regulation of an LED comprises a converter having a switch. The LED is interconnected in an output circuit, wherein a control unit controls the magnetization of an inductor, in that it actively clocks the switch. A measured actual value representative of the average value of the LED current is returned to the control unit and compared to a reference value.
