Bright idea illuminates LED standards
The lack of common measurement methods among light-emitting diode (LED) and lighting manufacturers has affected the commercialization of solid-state lighting products. view more (2008-11-26)
Artificial night lighting jeopardises the survival of sea life
Artificial night lighting can jeopardise the survival of sea turtles by obliterating environmental cues. Writing in the August issue of Biologist, Mike Salmon, of Florida Atlantic University, USA, explains how artificial coastal lighting disturbs female sea turtles' navigation to nest beaches and disorientates their hatchlings so that many fail to... view more...

Standards set for energy-conserving LED lighting
Scientists at the National Institute of Standards and Technology (NIST), in cooperation with national standards organizations, have taken the lead in developing the first two standards for solid-state lighting in the United States. view more (2008-06-30)
The Green (and blue, red, and white) lights of the future
A revolution in energy-efficient, environmentally-sound, and powerfully-flexible lighting is coming to businesses and homes, according to a paper in latest special energy issue of Optics Express, the Optical Society's (OSA) open-access journal. view more (2008-12-17)
Why white light is best for our town centres
White lighting is twice as good at letting you see the face of someone else as that from the yellow light from high pressure sodium lamps commonly used to light our streets, according to new research sponsored by the ESRC and published as part of Social Science week. It can therefore allow the same facial recognition as conventional sodium... view more... (2004-06-22)
Highways Agency congratulated for environmentally friendly lighting
Lighting that shines in a controlled manner rather than skywards, has resulted in the Highways Agency being congratulated by the House of Commons Science and Technology Committee recently. The Committee praised the Agency for forward thinking, and believes the high pressure sodium lanterns are a step in the right direction to reducing light... view more... (2003-12-01)
Turkeys with toys facing Christmas with a smile
"Turkeys can be aggressive birds and they do quite a bit of damage with their beaks," said animal behaviour researcher Michael Forbes. "By reducing this pecking we are improving the welfare of farmed birds, which should then increase consumer confidence in the way turkeys are reared." Over ten million turkeys are destined for British dinner plates... view more... (1999-12-06)
New materials for high efficiency organic solid state lighting
A new organic molecule developed by Pacific Northwest National Laboratory scientists may significantly improve the efficiency of organic solid state lighting. Direct conversion of electricity to light in "solid state" thin films of organic molecules occurs in organic light emitting devices which can be far more efficient than... view more... (2006-03-30)
Boston University partners in NSF challenge to create wireless network using visible light
Boston University's College of Engineering is a partner launching a major program, under a National Science Foundation grant, to develop the next generation of wireless communications technology based on visible light instead of radio waves. view more (2008-10-07)
Dartmouth Professor finds that iconic Oswald photo was not faked
Dartmouth Computer Scientist Hany Farid has new evidence regarding a photograph of accused John F. Kennedy assassin Lee Harvey Oswald. Farid, a pioneer in the field of digital forensics, digitally analyzed an iconic image of Oswald pictured in a backyard setting holding a rifle in one hand and Marxist newspapers in the other. view more (2009-11-06)
Engineering the road to safer streetlighting
An innovative engineering project could lead to fewer night-time accidents on badly lit roads. It is developing a revolutionary way of assessing whether roads are equipped with appropriate levels of streetlighting. The new assessment system is quicker, cheaper and more comprehensive than methods previously used. It can also help local... view more... (2002-12-09)
ORNL helps develop next-generation LEDs
Nanotechnology may unlock the secret for creating highly efficient next-generation LED lighting systems, and exploring its potential is the aim of several projects centered at Oak Ridge National Laboratory. view more (2007-03-20)
Smart Lighting: New LED Drops the 'Droop'
Researchers at Rensselaer Polytechnic Institute have developed and demonstrated a new type of light emitting diode (LED) with significantly improved lighting performance and energy efficiency. view more (2009-01-14)
Are we trading energy conservation for toxic air emissions?
A team of Yale scientists has found that certain countries and some U.S. states stand to benefit from the use of compact fluorescent lighting more than others in the fight against global warming. Some places may even produce more mercury emissions by switching from incandescent light bulbs to compact fluorescent lighting. view more (2008-10-01)
Optical wireless and broadband over power lines: High speed, secure Wi-Fi alternative
Penn State engineers have shown that a white-LED system for lighting and high data-rate indoor wireless communications, coupled with broadband over either medium- or low-voltage power line grids (BPL), can offer transmission capacities that exceed DSL or cable and are more secure than RF. view more (2006-01-12)
Researchers lay out vision for lighting 'revolution'
A "revolution" in the way we illuminate our world is imminent, according to a paper published this week by two professors at Rensselaer Polytechnic Institute. view more (2008-12-19)
University Jaume I researchers at work on EU project to improve video game realism
A group of researchers from the Department of Computer Languages and Systems at the Universitat Jaume I is taking part in a project to improve realism in video games. The goal is to design software that makes the task of game programmers easier so that they can create more credible environments without having to carry out complex operations. The... view more...

Flexible Solar Strips Light Up Campus Bus Shelter
There won't be anymore waiting in the dark at this campus bus shelter. New flexible solar cell technology developed by a group of engineering researchers at McMaster University has been installed to power lighting for night-time transit users. view more (2009-06-15)
Freeing light shines promise on energy-efficient lighting
The latest bright idea in energy-efficient lighting for homes and offices uses big science in nano-small packages to dim the future Edison's light bulb. view more (2008-07-16)
New Research could benefit drivers who are sensitive to night-time glare conditions
A new technique to measure the effect of bright light on the human eye could result in safer and more user-friendly lighting conditions. The technique, which records the electrical activity of a major muscle surrounding the eye, opens the way to measuring the discomfort of the eye in conditions of changing light. This could have important... view more... (2001-09-26)
