  • Indoor positioning energy-saving lighting device and its navigation system
    Patent number: 10741074
    Abstract: An indoor positioning energy-saving lighting device has a central processing module, a light source control module, a motion sensing module, a communication module, and an indoor positioning module. The light source control module, the motion sensing module, the communication module, and the indoor positioning module are electrically connected to the central processing module. The motion sensing module continuously sends out an identification code and a turn-on message. The motion sensing module senses a movement of an object or the communication module receives the light-on message, the light source control module controls the light source to illuminate, and the indoor positioning module is used to memorize the location information of other indoor positioning energy-saving lighting devices and position information of an external gyroscope received by the communication module.
