Abstract (en)

[origin: WO2020182427A1] The invention relates to a control and/or regulating means for controlling and/or regulating a light-emitting diode field with n light-emitting diodes, comprising outputs at which control and/or regulating signals can be tapped in order to control and/or regulate controllable switching elements. Switch-on times and/or switch-off times of pulses can be defined by the control and/or regulating means using the control signals and/or regulating signals, and one and/or more controllable switching elements can be actuated during the ascertained pulse for an opening or closing process. A number of k groups can be defined or is defined, and each LED is assigned to one of the k groups such that each of the k groups mj contains light-emitting diodes, wherein 1 ≤ j ≤ k, formula I is (FI), and the ascertained switch-on times and/or switch-off times of the pulses of each group are defined by the control and/or regulating means such that the pulses overlap as little as possible.
