Efficient Lights in Any Shape

Written by , on December 9, 2012

Researchers at Wake Forest University in North Carolina have reported that they have developed a  plastic material that glows when an electric current runs through it. The material, which can be formed in any shape, gives off a soft, white light, similar to sunkight, and is just as energy efficient as LEDs. The researchers made […]  Read more »

CO2 Absorbing Street Lights

Written by , on May 19, 2012

French biochemist Pierre Calleja has developed a lighting system that draws CO2 from the atmosphere and uses micro-algae to produce light with oxygen as a byproduct.  The inventor claims that one of his street lights will absorb CO2 at the rate of one tonne a year – which is about as much as a typical […]  Read more »

LED Lighting Advances

Written by , on May 12, 2012

At the recent Lightfair Internation in Las Vagas, GE, Phillips and Sylvania all announced LED light bulbs with an output equivalent to a 100-watt incandescent bulb. The Philips and Sylvania bulbs are extensions of current technology but the GE bulb is cooled by "breathing". A diaphragm embedded in the GE bulb vibrates to create a […]  Read more »

Street Lighting System Reduces Power Consumption by 80%

Written by , on July 18, 2011

Delft University of Technology is currently testing an intelligent street lighting system which reduces electricity consumption and CO2 emissions by up to 80%, reduces light pollution and is cheaper to maintain than current systems. The system, which was designed by Chintan Shah for a competition to improve the University’s energy efficiency, consists of LED street […]  Read more »

Sensor System Could Cut Lighting Costs by More Than Half

Written by , on November 23, 2010

Researchers at the Massachusetts Institute of Technology have developed a lighting control system which they say can reduce power usage by 65 to 90% beyond the savings made by switching to efficient light sources, such as LEDs. The system consists of control devices, about the size of a business card, that can be placed on […]  Read more »

Inexpensive Alternative to OLEDs

Written by , on February 6, 2010

Swedish and American researchers have succeeded in producing a new type of lighting component that is inexpensive to produce and can be fully recycled. The invention paves the way for glowing wallpaper made entirely of recylclable plastic. OLEDs (organic light-emitting diodes) have recently been introduced commercially in some mobile phones, cameras and TVs. These consist […]  Read more »

How Many New Yorkers Will It Take to Change All the Lightbulbs?

Written by , on December 20, 2008

The New York Department of Transportation has contracted a lighting design group, the Office of Visual Interaction, to trial LED street lighting. If the trial is successful, the city intends to replace all of its 300,000 street lights The contract includes the complete redesign of lamp posts – with the new ones having dedicated channels […]  Read more »

Cheaper LEDs

Written by , on July 21, 2008

Researchers at Purdue University in Indiana have reported that they have succeeded in overcoming a major obstacle in the production of low-cost LEDs. LEDs are far more efficient and have a much longer life than traditional incandescent lights. However, current LEDs are also much more expensive to produce. One of the major factors in the […]  Read more »
