Abstract (en)
[origin: WO2019126583A1] An illumination system is disclosed that provides a control signal interface configured to provide a voltage control signal via a control channel. A light engine is provided and includes a first signal generator configured to provide a first pulse-width modulated (PWM) signal based on the control signal, via a first channel, a second signal generator configured to provide a second PWM signal based on the control signal, via a second channel, and a third signal generator configured to provide a third PWM signal based on the first PWM signal and the second PWM signal, via a third channel.
