    摘要： The invention relates to a ballast (101) for lighting means, comprising an actively switched power factor correction stage (102), which is implemented in a Totem Pole boost topology, comprising
    - a control circuit (103), which issues control signals for driving switches of the PFC stage (102),
    - wherein the control circuit (103) is on a floating potential and galvanically isolated from a ground potential of the ballast (101).

    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： A device (1) of a lighting technology network (2) is provided. The device (1) comprises one or more antenna units (102) being configured to communicate in respective preferential directions (103). The device (1) further comprises a processing unit (101). The processing unit (101) is configured to determine, in a commissioning phase of the device (1), an association of each further device (1) of the lighting technology network (2) with a respective preferential direction (103) of a respective one of the antenna units (102) that enables a radio connectivity between the device (1) and the respective further device (1). The processing unit (101) is further configured to communicate, in an operating phase of the device (1), to the further devices (1) using the associated one of the antenna units (102) in the associated preferential direction (103). By communicating to a further device (1) using the associated antenna unit (102) in the associated preferential direction (103), a probability of collisions is reduced in an operation phase of the device (1).
