The primary goal of the research is to develop LEDs

It’s reported that new research from Boston University's College of Engineering, funded by a National Science Foundation grant, indicates that LEDs may be not only the integral lighting component of the future, but may also form the backbone of future wireless networks. The US government is funding research into using next-generation led high bay light as data network access points. Room or street lamps would link with devices using visible light, carrying data beyond over existing power lines. The primary goal of the research is to develop LEDs that do exactly that -- transmit information wirelessly via controlled blinking.

The initiative is known as the Smart Lighting Engineering Research Centre, and will be carried forward at Boston University, Rensselaer Polytechnic Institute and the University of New Mexico. The US National Science Foundation is providing $18.5m in funding.Little and his colleagues envisage affordable devices which would replace existing lamps and light fittings, usually requiring only the already-present power lines for backhaul. Devices equipped with visible-light ports not unlike IrDA kit would have a data connection whenever such a lamp was in line of sight. The data would be transmitted by the same LEDs which provided white-light illumination, flickering like tremendously fast signal lamps. The data flicker would be imperceptible to humans.

As visible light doesn't penetrate walls or travel round corners, the developers say that the system would be more secure than present-day WiFi, and would avoid the problem of multiple radio networks competing for bandwidth. Furthermore, the much higher frequency of visible light compared to radio waves would mean there was much more wireless bandwidth to use.Meanwhile, the lighting function of the LED access devices would also save useful amounts of led flood light, being much more efficient than existing filament or even fluorescent bulbs and tubes. The Smart Lighting advocates reckon that their kit could become truly ubiquitous, present in almost every place there is a light today - on cars and in streets as well as inside buildings.

while all of hit new record quarterly highs

As a result, to increase greenhouse yields and decrease producers' energy costs, they will team up with Rutgers University, the University of Arizona, Michigan State University, and Orbital Technologies Corp. on the four-year project to improve and evaluate LED lighting for greenhouse use, according to Cary Mitchell, a professor of horticulture and project director for the grant. Total sales from January through September of 2010 hit NT$92.88 billion, up 35% YoY. Meanwhile, operating profit and net profit reached NT$5.67 billion and NT$6.8 billion respectively, with accumulated EPS of NT$3.05 increasing a remarkable 50% YoY.
