New Development Direction of LED Optical Communication Technology

It is reported that in recent years, LED lighting as a low-carbon, energy-saving, environmentally friendly lighting equipment has been gradually understood by people, in the field of smart lighting as a strategic emerging industry vigorously supported by the national and local governments. It is favored by the industry for its rich and colorful colors, long life, and strong safety performance. It gradually eliminates ordinary lighting (such as incandescent lamps) from the lighting market. Experts predict that around 2015, LED lighting will become popular. A few days ago a research report showed that: LED lighting research has the latest technological breakthroughs - it can be directly connected to broadband networks through LED lighting.

LED light source supports broadband connection

A computer can be placed under the illumination of a LED light, and the network broadband connection can be smoothly performed without a network cable connection and a wireless built-in port. Complete web browsing, video playback, and many other network functions. The secret of this is the LED lighting on the roof. According to experts, Unicom's network signal is transmitted to the computer via LED light. The maximum transmission rate measured through this method can reach 2 megabits per second.

Breakthrough in LED technology breakthroughs

In fact, since the birth of the LED concept, technological breakthroughs have emerged in an endless stream. Foreign IAO studios have developed LED virtual sky panels. It uses LED light bulbs to simulate the sky and sunshine, thereby replacing the ceiling of a traditional office, to create a relaxed and happy working environment, and to increase employee productivity. And the energy saving effect of LED bulbs is 8 times higher than that of traditional white light bulbs. It can also achieve a win-win effect for companies to save electricity and improve work efficiency.

So it is not surprising that the connection network function is realized. In addition, LED lights can also play the role of commander of household appliances. Some experts introduced: Through certain technical means LED lighting has been able to achieve a variety of electrical switches and adjustment control. How does LED light transmit network signal and control signal through light? Experts further explained that LED light is different from traditional lighting equipment in that it not only saves energy, but also can send out modulated signals through high-speed switching actions to complete information and instructions. Transmission. Switching speeds up to 2 million times per second, so non-stop switching will not affect normal lighting use. It will not affect the human body because human eyes do not see such rapid frequency changes at all.

LED wireless communication technology into a new direction for the development of science and technology

People have been enjoying the convenient services of wireless networks all along. They are also worried that the radiation generated by it may have a negative impact on the human body. However, using the environmentally friendly LED lighting to surf the Internet can completely eliminate this concern. Although compared with wireless technology, LED lighting internet access is still only a potential stock. However, its special information transmission method can reach an access speed of more than 1G per second in the future. It is understood that in addition to LED lighting in the field of smart development potential, both at home and abroad have also begun on the further research and development of LED wireless communication technology research and development, which may become a new direction of future scientific and technological development.
