    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).

When the first switch (S1) is activated energy is temporarily stored in the coil (L1) and when the first switch (S1) is deactivated said energy is discharged via a diode (D1) and via at least one LED. The control/regulation unit (SR) activates the first switch (S1) when a reactivation condition has been met, and the control/regulation unit (SR) deactivates the first switch (S1) when a deactivation condition has been met. Said reactivation condition and/or deactivation condition can be set in accordance with the current dimming level.
