The realization of wireless internet access technology to overcome the problem of flight LED

LED street lamp, LED display, LED as an energy-saving lighting equipment has gradually entered our lives. But do you know that the light emitted by the LED can be connected to the broadband network, which has become a reality in the current scientific research. From the Chinese Academy of Sciences Institute of LED lighting was informed that the study of LED lighting information has made a major breakthrough.

Wireless internet access

A laptop is placed under the light, there is no cable connection, no wireless network card, but the smooth network video is still playing...... This is the scene yesterday in the Chinese Academy of Sciences LED lighting LED lighting and Information Technology Museum in the scene. Why is there such a situation? Dr Duan Jingyuan, of the photovoltaic systems laboratory, reached out and pointed out that the secret lies in the blue LED lights on the ceiling.

He explained that the network signal is transmitted to the computer through the light. In this way, the current maximum transmission rate can reach 2 megabits per second.

In addition to connecting the network, LED lights can also serve as a variety of home appliances commander. The Institute of Dr. Chen Xiongbin, at present, they have achieved a variety of electrical switches and regulation control. These two technologies have been carried out in World Expo, respectively, in the Aviation Museum and the Shanghai museum.

High speed switching information

How does the LED light transmit the network signal and the control signal through the light? Experts, LED lamp is a new type of lighting equipment, different from the traditional lighting equipment, it is not only energy saving, but also through high-speed switching action, issued a modulated signal, complete the transmission of information and instructions.

Do not switch the action will affect the normal use of lighting it? The answer was No. Researchers, the switch can be up to 2 million times per second, the naked eye can not feel.

To overcome the problem of flight Internet

Now people enjoy the convenient wireless network services at the same time, also in constant fear of electromagnetic waves produced by it may have an adverse impact on the human body, and LED lighting environmental protection Internet can completely eliminate the concerns. No electromagnetic waves will not cause interference to the surrounding electronic equipment, wireless internet access will also be resolved in the plane, even in the water, a beam of light coming in LED, you can complete the high-speed transmission of network signals.

Experts, compared with the current wireless technology, LED lighting is only a potential stock. Because of its special way of information transmission, it can reach G access speed per second in the future. It is understood that the United States, Japan and Europe have begun on the development of LED wireless communication technology, which may become an important direction for future development of science and technology.
