LED home lighting into the era of wireless network control

It will not be long before the lights can be used to illuminate the darkness - they can also wirelessly connect your computer, phone or car to the internet.

That sounds strange, doesn't it? But you can imagine. The remote control has used the infrared light to control the TV and the DVD player. The ceiling lamp and reading lights for wireless access point can be installed anywhere you want the internet.

Of course, this is not a light can do. Little and other researchers hope to work in a light emitting diode (LED) lamp bulb has confirmed this popularity, than it is now commonly used incandescent lamp and fluorescent lamp with low energy, more durable, it is a good substitute.

Communicate with light

It's not news to communicate with light. The Romans used the fire to communicate between the castles, and the lighthouse reminded the ship to avoid the danger zone. NASA and the US military recently in the study of using laser as a direct and rapid means of communication.

Today, however, the most common wireless network technology is radio frequency. With more Internet users and devices in the same band, those bands will be crowded and busy, and the browsing speed will slow down.

"It's like being at a cocktail party," Little told LiveScience. He explained that when a lot of people are talking, the voice gets bigger and bigger.

The light of the information through direct access to individual users and devices to avoid the problem of congestion, whether through a very narrow laser or in a large area of light bulbs. Information will first be sent from a wireless router by a ceiling lamp or a lamp on a wire, and then the LED lamp can be transformed into a data source that can not be detected by the naked eye.

Another advantage is that the system is more secure because the light does not travel through the walls like radio waves. The wireless network cannot be installed in the room where the lights go beyond the walls. Those who want to take the Internet free wireless Internet neighbors must be issued outside the squat lights in the windows in your home.

Green wireless network

Little and her researchers have invented a prototype that can be used with a modified wireless router and a flashlight LED. The next important step in their plan is to rely on the LED bulb to become popular around the world.

LED lights have been everywhere, from the computer screen to the traffic lights, but the popularity of household lights on the slow, because each bulb costs $30 or more. However, a LED bulb can be used for more than 50000 hours, compared to the life of the fluorescent lamp is only 1000 hours, and LED compared to power saving, so it is more cost-effective to use.

Little said: "this is a very important structure of LED compared to a fluorescent light bulb lighting can bring unexpected energy savings," he added, as LED is widely used in various places, its price in the next 5 to 10 years is expected to decline.

Stylish home

Not only do we try to make cheaper wireless networks across the United states. Little talked about achieving all wireless connections in a "stylish" energy efficient home, including computers, TVs and air conditioning.

The outdoor application of the local network can also achieve communication between motor vehicles. A car through the anti lock brakes on the road into the ice on the road, and then its LED brake lights automatically spread some information to remind the car coming back.

"There are huge profits in the mobile industry and transportation industry," Little said. He pointed out that Audi's recent traffic lights have been changing rapidly, even though he thought it would be possible to use a common light instead of a radio transmitter.

The government backed the idea in dollars. Little and the other thirty from Boston University, Rensselaer Polytechnic Institute and University of New Mexico researchers from the National Science Foundation for $18 million 500 thousand as the cost of technology development for five years.

Several World Co are also negotiating the use of this technology transaction, which means that sooner or later to see its application.
