Light provides wireless Internet access? LED lights to help you achieve

A laptop can be placed under the illumination of a light, and the network video can be played smoothly without a network cable connection and without a wireless network card. The secret of this is the blue LED lighting on the ceiling. According to Dr. Duan Jingyuan from the Photovoltaic 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.

In addition to connecting to the network, LED lights can also act as commanders for a variety of household appliances. Dr. Chen Xiongbin from the institute said that they have now realized the control of switching and regulating various electrical appliances. These two technologies have also been displayed at the Aviation Pavilion of the World Expo and the Eco-House in Shanghai.

And how does the LED light transmit network signals and control signals through light? Experts say that LED lights are new types of lighting equipment. Unlike traditional lighting equipment, it not only saves electricity, but also emits modulated signals through high-speed switching action. , complete the transmission of information and instructions. According to scientific research personnel, the speed of switching per second can reach 2 million times, which cannot be felt by the naked eye. , so the non-stop switching action will not affect the normal lighting use.

Nowadays, while people enjoy the convenient service of wireless network, they are also worried that the electromagnetic waves generated by it may have adverse effects on the human body, and the use of environmentally friendly LED lighting can completely eliminate this concern. Without electromagnetic waves, it will not cause interference to surrounding electronic equipment. The problem of wireless Internet access in the aircraft will also be solved. Even under water, a bundle of LED lights can complete the high-speed transmission of network signals.

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.
