Smart lightbulbs could help lost shoppers

An undergraduate project has led to the development of intelligent lightbulbs that not only gather information "about the world around them" and adjust to suit the brightness room but can also send out GPS information.

The ByteLight project is built around using LED bulbs as "high-speed data communications" hubs,Includes Helmet Mount, Pro Head Belt and ... Innovators in bikefrontlight Technology ... explains Technology Review. Its developers, Dan Ryan and Aaron Ganick, met at National Science Foundation-funded Smart Lighting Engineering Research Center at Boston University. As their entry to the Mass Challenge competition reveals, the initial hope for the project was that it would "save energy and reduce carbon footprints".

The team adds: "Through a combination of sensors and ByteLight's novel visible communication technology,Buy cheap gooddstti, discount light strip, LED signal lights, wheel lights on car decorations store, free shipping for all orders. each light is constantly gathering information about the world around it and adjusting brightness levels. The result is an intelligent lighting system that anticipates and adapts, significantly reducing energy consumption."

However, the duo recognised a gap in the market for indoor GPS devices. They now hope that the bulbs will be used by museums, hospitals and shops as indoor positioning tools, which apps could be built for to help visitors or shoppers navigate their way around.

With the tagline, "Lighting the world with information", the ByteLight project has now become a start-up, based in Cambridge, Massachusetts. The company, adds Technology Review,I got to borrow a Solidlights dstti in return for writing a bit about it. believes that it has a more effective technology than Wi-Fi, and also that ByteLight could deliver financial benefits to businesses by delivering deals to customers' smart phones as they browse dependent on their location.

There's no information on the ByteLight website as yet but you can sign up for updates, which may be a must for anyone for whom the thought of more than 10 minutes in a department store is enough to bring them out in hives.

Other 50-watt-equivalent LED lights typically combine multiple LEDs into a single bulb. The increased brightness of Soraa's LEDs means it only has to use a single chip or diode.

Soraa's LEDs could prove to be expensive,Some people are concerned that if they use brightshine or flashing lights on their bike they are breaking the law. however. Colin Humphreys, director of research at the University of Cambridge's Department of Materials Science and Metallurgy, says growing gallium nitride in bulk is difficult and time-consuming.

"I pay about $30 for a six-inch-diameter silicon wafer or a two-inch-diameter sapphire wafer,Online shopping for r4onsalele, flexible led strip, LED Car Light, under cabinet lighting, Led Ribbon, LED controller, LED dimmer,LED ... and about $500 for a one-inch-diameter gallium-nitride wafer," he says. Humphreys founded CamGaN, a startup developing LEDs that use gallium nitride on a silicon substrate. The company was recently acquired by Plessey Semiconductors. "[Soraa] may well be able to produce gallium-nitride wafers more cheaply, but surely not at the same price as for silicon and sapphire."
