The researchers combined wireless networks and optical to convert LED light into network device that helped user’s smart phone or computer to receive or send data in Germany F Rauen Hoff Applied Research Institute. It is reported that the technology research and development can make use of flashing LED lights to transmit data from the air, the transmission speeds is up to 1,000 megabytes per second, and express different transmission data rate with three different colors of LED lighting,. |
LED lights are very popular in our daily lives, whether in the room, offices, streets we can find the product. In addition to LED lights provide illumination for us, doesn’t it have no more powerful?
The Institute’s researchers Anagnostis Paraskevopoulos said he personally thought that the first test of the technology would be put to use in meeting room, exhibition, industrial production environment, and more professional hospitals and other places.
But he also said that such technology would lead to a series of questions. For example, if the LED lights adopt battery powered, which means that receiving signal will be better within a short range. Another problem is that the strong sunlight will affect the LED light signal receiver, which make some damage to outdoor LED apparatus. As the change in distance ,it will change its performance, the transmission speed is 20 megabytes per second outside the range of 20 meters.
In addition, the visible light communication also requires line of sight communication conditions, after all, the light can not penetrate walls. However, by coordinating all LED lights each other in the room, you can still received signal i in any one corner of the room.
The limitations of this research lies in that not every user wants their phone or computer to receive the signal, it must have a head glowing LED lights. But the research team, said research and develop or introduce invisible infrared light LED lights in future.
LED lighting is currently more and more high-tech and practical, it is unlike incandescent and fluorescent lamps, which just satisfy our demand for general lighting, as the high-tech semiconductor LED lighting, it has been innovating so that closely linked in our daily life we just to try and develop high-tech life in term of LED lighting connecting to the Internet, perhaps in the near future it will spread to everyday life, but LED has entered our lives using for commercial lighting and home lighting in real life, we can see LED flood light and LED tunnel lights in our city squares, stadiums, parks, shopping centers, road and rail tunnels, LED tube s is widely used in the underground supermarkets, car parks, office building, as LED lighting R & D and production enterprise, Li Sida Lighting http://www.lead-lighting.com make effort to develop and produce energy-saving LED lighting that is closer to our lives and mass consumption, lead us forward to high-tech green energy.
