Connected bulb rc latch optimized for low standby power

Abstract

The invention relates to a driver for driving a lighting load, the driver comprising a rectifier adapted to receive an alternating current, AC, input voltage and adapted to provide a rectified voltage, a converter adapted to convert the rectified voltage into an output voltage for the lighting load, a controller for controlling the converter and a switching element, and a latching circuit adapted to receive the alternating input voltage or the rectified voltage and comprising a series combination of a resistor, a capacitor and the switching element, wherein the controller is arranged to configure the converter in an active mode and a stand-by mode, close the switching element when the controller configures the converter in the active mode, and open the switching element when the controller configures the converter in the stand-by mode.
