1. A lighting system comprising:

  • a lighting device,a power supply for powering the lighting device, anda switch electrically connecting the lighting device with the power supply wherein the switch is switchable between a high-power state, in which a higher power is provided to the lighting device via the switch, which allows the lighting device to emit the light in high-power mode, and a low-power state, in which a lower power is provided to the lighting device via the switch, which allows the lighting device to provide a further function in a low power mode,wherein the power supply is configured to supply AC power as the higher power and wherein the switch is configured to provide the higher power in the high-power state, and provide DC power as the lower power in the low-power state, andwherein the further function is at least one of a sensing function, processing function, and communication function,wherein the switch comprises a switching element, wherein the switch is configured such that in the high-power state the switching element is conducting, in order to provide the higher power to the lighting device via the switching element, and in the low-power state the switching element is not conducting, in order to provide power to the lighting device via a resistor or capacitor in the switch, wherein the resistor or capacitor is adapted such that in the low-power state the higher power supplied by the power supply is reduced to the lower power.
