Lighting device and method of operation

A localization system comprising:

• a first lighting device, comprising:
• an ultra-wideband (UWB) communication unit;
• a mode controller operatively coupled to the UWB communication unit;
• wherein the mode controller is configured to cause the UWB communication unit to operate in a radar mode;
• and
• wherein the UWB communication unit is configured to, while operating in said radar mode, detect at least one living object present within a predefined area around or near the lighting device;
• one or more further lighting devices, wherein each of the one or more further lighting devices includes a further UWB communication unit configured to operate in the radar mode;
• and
• a system controller configured to control the lighting device and the one or more further lighting devices and to determine at least one of the position of the living object within the predefined area and the velocity of the living object by processing results of radar operations performed by the lighting device and the further lighting devices.

A method of operating a networkable lighting device, the lighting device comprising an ultra-wideband (UWB) communication unit and a mode controller operatively coupled to the UWB communication unit, the method comprising:

• causing, by the mode controller, the UWB communication unit to operate in a radar mode;
• detecting, by the UWB communication unit, while operating in said radar mode, at least one living object present within a predefined area around or near the lighting device;
• detecting, by the UWB communication unit, while operating in the radar mode, one or more properties of the living object, the one or more properties include one or more vital signs;
• sending, by the UWB communication unit, a UWB frame to a controller, the UWB frame including information indicative of the at least one living object and the one or more properties;
• and
• receiving, by the UWB communication unit from the controller, a UWB frame including instructions to control light emitted by the lighting device.

A non-transitory computer-readable medium storing machine instructions which, when executed by at least one processor, cause the at least one processor to:

• cause a mode controller to prompt an ultra-wideband (UWB) communication unit to operate in a radar mode, wherein the mode controller and the UWB communication unit are included in a lighting device;
• cause the UWB communication unit to detect, while operating in said radar mode, one or more properties of at least one living object present within a predefined area around or near the lighting device, the one or more properties including at least one vital sign associated with living object;
• and
• cause the UWB communication unit to send a UWB frame to control light emitted by one or more external lighting devices in response to detecting the one or more properties of the at least one living object.
