Schaltungsanordnung und Verfahren für eine Beleuchtungseinrichtung mit einstellbarer Farbe und Helligkeit

摘要

The switching arrangement includes first and second control units (E1,E2). The first control unit controls the power output of first and second power supplies (CON,PWM1,PWM2). The second control unit allows controlling of only the second power supply. The first power supply controls the power supply to a first group of light sources (G1) and the second power supply controls the power supply to a second group of light sources (G2).
