Abstract

The invention relates to an operating device for lighting means (400), comprising: output terminals (407a, 407b) supplying lighting means (408), such as e.g. a LED load, a control circuitry (404) for controlling the electrical supply of the lighting means (408); a NFC module (406) configured to receive NFC signals and output a pulse width modulation, PWM, signal with variable duty cycle; and a conversion circuitry (405) arranged for being supplied with the PWM signal and for outputting a DC voltage supplied to an input of the control circuitry (404). The DC voltage is a function of the duty cycle of the PWM signal according to a set conversion rate, wherein the conversion circuitry (405) is configured to be supplied with an internal or external control signal to set at least two conversion rates.
