Abstract (en)
[origin: WO2017186968A1] The invention relates to a method for controlling an LED module by means of a half-bridge circuit with two switches or a full-bridge circuit with four switches, wherein the LED module (EL) is connected in the bridge branch and a diagonal bridge section is activated, wherein a switch (S1, S2) is actively clocked, wherein the LED module has two antiparallel strands, wherein the two antiparallel strands differ in each strand, in particular by a different colour temperature or wavelength of the corresponding LED.
