Zhuhai Huace Group signed a transferee of patent technology LED white light communication

24 days, reporters from the Zhuhai Huace group was informed that the group of 23 and the National Key Laboratory of semiconductor joint innovation in Jiangsu province held in Changzhou base of white light LED communication project cooperation signing ceremony.

According to reports, Vice Minister of science and technology of China, Cao Jianlin, vice governor of Jiangsu Province, he has more than 200 leaders attended the signing ceremony.

According to the National Key Laboratory of semiconductor joint innovation experts, LED white light communication technology referred to as visible light communication technology is a new technology, one of the developed countries in the world have developed, its principle is to compile the information to be transmitted into a special signal with pulse width modulation method of this signal is attached to the drive current of LED lamp on so, LED has a very high frequency of flashing lights. Although the human eye can not see the flicker, but through the photosensitive device can detect the frequency flicker, and restore it to the transmission of information, thus completing the information transmission through the lamp to the technology has the advantages of high security, do not take advantage of wireless channel resources.

LED white light communication technology can also be widely distributed in the interior of each lamp as a positioning reference point, which is similar to the GPS system in the "satellite", to achieve accurate indoor positioning. Its accuracy can reach more than 10 times that of traditional technology.

It is reported that the State Key Laboratory of semiconductor joint innovation fundamentally solve the white light communication and white light positioning of a series of theoretical issues, has now submitted 8 invention patents.

Zhuhai Huace group is a real estate development, integrated run lighting, communications, international trade, hotel and education as one of the multinational corporations. This year, the company based on the basis of the degree of potential industrial transfer, spending huge sums into the technology industry, white light communication technology development and National Key Laboratory of semiconductor joint innovation together in advance of the technology industrialization process, fill in the gaps in the field of Chinese.
