Lighting system
First Claim
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.

Abstract
The invention relates to a lighting system (1) comprising a lighting device (3) for emitting light in a high-power mode and for providing a further function like a sensing function in a low-power mode and a switch (4) connecting the lighting device with a power supply (2). 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 the high-power mode, and which may be regarded as being an ON state, 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 the further function, and which may be regarded as being an OFF state. Thus, for instance, a sensing function can be provided, even if the switch is in its OFF state.
