Abstract
A lighting device includes an ultra-wideband (UWB) sensor module configured to detect movement, a light source module having a plurality of light emitting diodes (LEDs), and a driver configured to drive the plurality of LEDs, and a first controller connected to the light source module and the UWB sensor module, the first controller being configured to receive setting data from an external control device, output the setting data to the UWB sensor module to cause the UWB sensor module to set at least one operational parameter of the UWB sensor module, and output a control signal to the driver to cause the driver to drive the plurality of LEDs.
Claims16
A lighting device comprising:
- an ultra-wideband (UWB) sensor module configured to detect movement;
- a light source module having
- a plurality of light emitting diodes (LEDs), and
- a driver configured to drive the plurality of LEDs;
- and
- a first controller connected to the light source module and the UWB sensor module, the first controller being configured to
- receive setting data from an external control device,
- output the setting data to the UWB sensor module to cause the UWB sensor module to set at least one operational parameter of the UWB sensor module, and
- output a control signal to the driver to cause the driver to drive the plurality of LEDs,
- wherein the UWB sensor module comprises:
- an UWB sensor configured to generate a pulse signal, transmit the generated pulse signal, and receive a signal reflected from an object;
- and
- a second controller configured to control operations of the UWB sensor, and process the signal.
A lighting system comprising:
- a lighting device configured to
- detect movement using an UWB sensor, the detection being based on setting data, and
- drive a plurality of LEDs based on the detected movement;
- and
- a control device connected to the lighting device, the control device being configured to provide the setting data to the lighting device,
- wherein the lighting device comprises:
- an UWB sensor module having the UWB sensor;
- a light source module having the plurality of LEDs;
- a driver driving the plurality of LEDs;
- and
- a first controller connected to the light source module and the UWB sensor module, the first controller being configured to
- receive the setting data from the control device,
- output the setting data to the UWB sensor module to set operations of the UWB sensor module, and
- output a control signal to the driver to cause the driver to drive the plurality of LEDs,
- wherein
- the UWB sensor is configured to generate a pulse signal, transmit the generated pulse signal, and receive a signal reflected from an object;
- and
- the UWB sensor module comprises:
- a second controller configured to control operations of the UWB sensor, and process the signal.
