On December 23, Zhuhai Huace Group Co., Ltd. and the State Key Laboratory of Semiconductor Joint Innovation held a signing ceremony for the cooperation of LED white light communication project in Changzhou, Jiangsu Province. Huace Group officially signed the patented technology for LED white light communication.
LED white light communication technology, referred to as visible light technology, is an emerging communication technology developed by the world's developed countries. The principle is to compile the information to be transmitted into a special signal, and add this signal to the driving current of the LED lamp by pulse width modulation, so that the LED lamp flashes at a very high frequency. It can also use each luminaire in a wide range of indoors as a positioning reference point, the "satellite" in the GPS system, to achieve accurate positioning in the room. Its accuracy can reach more than 10 times that of traditional technology.
