    摘要： 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 (Si) 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 (S2) a temporal course of temperature of the electrical component based on the two or more estimated temperatures; and computing (S 3 ), 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.

    摘要： Concerning the field of power electronics and lighting, the method for controlling at least one driver device, in particular a light driver, controls the at least one driver device to operate either in a standby mode or in a power-supplying mode. The method comprises obtaining a parameter value, evaluating the obtained parameter value to determine whether the obtained parameter value meets a lifecycle-criterion, and switching the at least one driver device into a lifetime-preserving mode in case the obtained parameter value meets the lifecycle criterion. In the lifetime-preserving mode, an adjustable value of at least one operational parameter of the at least one driver device is set to reduce a temperature spread of a device temperature of the at least one driver device. A control circuit for a driver device, e.g. a light driver, the driver device, a luminaire or a lighting system may implement the method.

    摘要： The invention concerns to the field of technical building infrastructure and, in particular, concerns a monitoring system for using light driver devices for obtaining and evaluating technical and environmental parameters within the building, a corresponding building infrastructure device and a corresponding monitoring method. The building infrastructure system includes the monitoring system. The monitoring system for monitoring at least one parameter from an environment of the building infrastructure system comprises a sensor circuit for obtaining sensor data on the at least one parameter, wherein the sensor circuit is arranged in a building infrastructure device. The monitoring system further comprises an evaluator circuit for generating an evaluation signal by evaluating the sensor data obtained by the sensor circuit. The at least one parameter is an environmental parameter or a technical parameter, which influences a plurality of devices of the building infrastructure system. The monitoring system is configured to provide the evaluation signal to at least one other infrastructure device.
