摘要： A device is configured to determine a switching pattern comprising a first time range for activating a first plurality of light emitting diodes (LEDs) of a LED module and a second time range for activating a second plurality of LEDs of the LED module. The first plurality of LEDs and the second plurality of LEDs are different. The device is further configured to determine, for each LED of the first plurality of LEDs, a respective timeslot of a plurality of timeslots of the first time range. The device is further configured to output an instruction to a switching device to cause the switching device to couple each LED of the first plurality of LEDs to a supply during the respective timeslot determined for the LED.
