How long the lamp can not light up the dark — not only for them but also your computer, phone or car radio to connect to the Internet. This sounds strange, right? But you can imagine the next. Have used infrared light remote control to remote control a TV and DVD player. The ceiling and reading lamps for wireless access points can do any of you install the Internet anywhere.

Of course this is not any light can do. Little and other researchers hope that the efforts of the light-emitting diode (LED) bulbs on the popularity of these bulbs have confirmed the general use than the current incandescent and fluorescent light bulbs low energy consumption, more durable, they a good substitute.

To communications with the lighting is not news. Romans used beacon for all communication between the castle, lighthouse to remind the vessel to avoid the coastal zone of danger. NASA and the U.S. Army recently in the research of laser as a direct, high-speed means of communication.
However, today’s most popular wireless network technology is dependent on radio frequency. As more Internet users and devices occupy the same band, that band will become very crowded and busy, the speed will slow down browsing.

“It’s like in a cocktail party,” Little told LiveScience, he explained, when a lot of people together, talking, the sound will be increasing. Light of the information through directly to individual users and devices to avoid the congestion problem, whether through a very narrow laser or LED light bulbs in a large area. Information will be first through the ceiling light or table lamp wire wireless router from a wireless issue, then LED lights in a human eye can not detect the flash mode conversion data.

Another advantage is the icing on the cake such a system more secure, because light can not pass through walls like radio waves. Installed in the lamp on the wireless network can not go beyond the four walls of the room where. Those ill-disposed to take up the neighbors free wireless Internet to be squatting in your house lights outside the window Caixing issued.

Little and her researchers have used a modified wireless router and flashlight LED lights invented a prototype that can be used. They plan to the next important step is necessary to rely on the worldwide popularity of LED bulbs.

LED lights have appeared everywhere, from computer screens to traffic lights, but in everyday household lamps spend popularity slowly because each bulb to spend 30 U.S. dollars or more. However, an LED bulb can last more than 50,000 hours, compared with only 1000 hours life lamps, and LED power compared to, so use them more cost-effective.

Little said: “This is very important, LED lighting structure compared to fluorescent bulbs can bring about energy savings,” he said, with a wide range LED applications in all areas, its price in the next 5 to 10 years expected to decline.

Not only to make a cheaper wireless network throughout the U.S. city. Little spoke in a very “in” energy efficient homes to achieve full wireless connectivity, including computers, television and air conditioning.

Outdoor applications of local networks can achieve the communication between vehicles. A car through the anti-lock braking sensors to vehicles on the road under the ice, and then it’s LED brake lights automatically came a message to the back of the car over.

“Mobile industry and transport industry there is a huge profit”, Little said. He pointed out that Audi has recently been on display traffic lights change color soon, although he envisaged normal light instead of radio transmission with a machine to inform the car.

Government dollars to support this idea. Little and the rest 30 from Boston University, Rensselaer Polytechnic Institute and researchers at the University of New Mexico received from the National Science Foundation, 18.5 million U.S. dollars for five years, the cost of the development of this technology.

Communications companies are some of the world using this technology, trade negotiations, which means that sooner or later will see its application.
