Abstract

The present invention provides a method for adjusting the illumination range in indoor visible light communication and an illumination device, wherein the method includes: receiving a signal sent by a terminal located within the circular illumination range of the illumination device on the ground; monitoring according to the signal The distance between the terminal and the center of the circle within the circular illumination range; when the maximum distance between the terminal and the center of the circle is detected to be less than the maximum illumination radius, and there is a terminal disconnected from the illumination device, the power of the illumination device is adjusted to the maximum power, and the illumination radius Adjust to the maximum illumination radius, where the maximum illumination radius is the illumination radius of the illumination device working at maximum power. The above technical solution achieves the technical effect of adjusting the illumination range of the lighting device as the indoor terminal moves without exceeding the maximum power of the lighting device.

Description

technical field [0001] The present invention relates to the field of visible light communication, in particular to a method and an illuminating device for adjusting an illumination range in indoor visible light communication. Background technique [0002] Indoor visible light communication technology, a specific lighting device is configured indoors, and the lighting device is equipped with a microchip. The microchip is connected to the router, receives Internet data from the router, and controls the lighting device according to the Internet data to send out signals invisible to the naked eye. The received high-speed bright and dark flashing signal, where bright means 1, and off means 0, the terminal under the light receives the signal through the optical / electrical converter. When the terminal under the light wants to send a signal, it first converts the signal to be sent into an optical signal through an electrical / optical converter and then sends it out, and the optical / e...
