According to the introduction of the staff of the photoelectric system laboratory of the LED Lighting Institute of the Chinese Academy of Sciences, the network signal is transmitted to the computer through the light. In this way, the current maximum transmission rate of the Internet can reach 2 megabits per second. According to experts, LED lights can transmit modulated signals through high-speed switching operations to complete the transmission of information and commands. The switching speed per second can reach 2 million times, which can't be felt by the naked eye, so the non-stop switching action will not affect the normal lighting use.
According to experts, LED lighting is only a potential stock compared with current wireless technology. Due to its special information transmission method, it can reach the access speed of G on every second in the future. It is understood that the United States, Japan and Europe have begun research and development on LED wireless communication technology, which may become an important direction for future technological development.
