Metro Red Line subway passengers are now seeing 15-second LED tunnel ads designed to generate more revenue for the transit agency as well as advertisers. The Los Angeles County Metropolitan Transportation Authority debuted the new electronic ads earlier this week with a flickering advertisement for the movie "Speed Racer." The video floats outside the train's window in a dark tunnel. The videos are actually 360 LED lights hung over a quarter-mile span of the tunnel. When trains go past the lights, the human eye perceives movement.

Faiz Rahman, a nanoelectronics researcher at the University of Glasgow, predicts that LED light bulbs for the home will start appearing on store shelves in the next 2-3 years to compete with incandescent and fluorescent bulbs.If so, the LED bulbs would provide a much greater efficiency (up to 70%) compared with incandescent (5%) and fluorescent (25%) bulbs.

Most people already know that excessive exposure to the sun is dangerous to the skin. UV light causes environmental damage, fine lines, wrinkles, dryness and spots. So how is it possible that a certain light therapy can actually be good for the skin? Skincare-News.com's latest article, "LED Light Therapy Treats Aging and More," explains the benefits of this new treatment. How LED works

This stunning LED chandelier lit up this year's BKLYN Designs with a stellar low-energy lighting solution for light emitting diodes.

In many of Africa's towns and villages, smoky kerosene lamps are all that keeps the darkness at bay after sunset. However, kerosene is a dangerous and increasingly expensive source of light for Africans who do not have access to electricity -- about three-quarters of those living on the continent, according to the World Bank. Lighting industry entrepreneurs are hoping alternative devices such as solar-powered LED lights will replace the kerosene lamps.

According to market research firm iSuppli,due to their low power consumption, thin form factor, light weight and environmental friendliness, LEDs are set to take the notebook PC display backlighting market by storm during the next few years, with nine out of 10 large-sized mobile PC LCD panels expected to use the technology by 2012.

LED lighting supplier Cree has launched LED University to promote and accelerate the adoption of LEDs by showcasing their use at universities. North Carolina State University, the first to sign up with the initiative, has installed recessed LED lighting in a dorm and chancellor's office and is putting in LED lighting in parking garages. The university reports LED lighting in the dorm has cut energy use by 66 percent so far.

Recently, the American government says that if every American home replaced one light bulb with a compact fluorescent light bulb, we could save enough energy to prevent greenhouse gases equal to the emissions of more than 800,000 cars. Certainly great news, yet recycling burned-out CFL light bulbs poses a quandary for homeowners.

The MacBook Air has become the best advertisement for why companies should use LED (light-emitting diode) backlights in notebook screens, and is driving adoption, according to market researcher DisplaySearch. LED backlights in display screens are an improvement over old CCFL (cold-cathode florescent lamps) technology for several reasons, including a stunning picture due to more vibrant contrasts, better power savings, and they're easier on the environment because they contain no mercury and last longer.

On April 8, 2008 Maryland Governor Martin O'Malley signed Senate Bill 713 authorizing the use of certain auxiliary lighting on motorcycles.Effective June 1, 2008, Maryland motorcyclists can legally ride with light emitting diode (LED) pods and strips on their motorcycle, provided they do not blink, oscillate, or flash and are not red or blue, as these colors are reserved for law enforcement and emergency vehicles. That leaves amber, green, hot pink, jade, orange, purple, and white.

The World's Largest LED Free-Hanging Chandelier was illuminated for the first time by Meyda Lighting on April 2nd, at the Stanley Center for the Arts in Utica, New York. Meyda Lighting, a Meyda Tiffany company and nation's leading manufacturer of decorative lighting, recently installed the chandelier after one year of planning and production in its manufacturing facilities.

Now when the lights go low, the bocce won't have to stop when you have these LED bocce balls. Included in the set are nine colored balls in white, yellow, red, green and blue that all have embedded LEDs.

The lights are a little whiter and a little brighter in part of St. Paul as part of an experiment with LED streetlights. The city's environmental policy director, Anne Hunt, says it is experimenting with the new lights because they are greener, last longer and cheaper to operate. Paul is following Austin, Texas; Anchorage, Alaska and Ann Arbor, Michigan, in installing the lights. A few smaller Minnesota cities have also tried them.

STMicroelectronics , a world leader in power applications, has introduced three monolithic step-up converters for LED backlights and lighting, providing 30mA or 85mA current sources for six rows of up to 10 white LEDs. The LED7706, LED7707 and mobile-optimized PM6600 include on-chip MOSFETs to reduce part count, and operate up to 1MHz to minimize filter components.

LED-backlit LCD TVs, enabled by Dolby Laboratories' High Dynamic Range (HDR) technology, produce stunning pictures. Unclear, though, is how much consumers will have to pay for that kind of picture quality. "These products have been screaming to get out to a mass market," said Eric Haruki, research director for TV markets and technologies at IDC. But he cautioned that unless LED manufacturers can achieve the economies of scale and cut the cost of LEDs, "this could still remain a great white hope for awhile."

Marumi's little ring-light uses LEDs instead of a flash tube, which has a couple of advantages. You can preview the light's effect on the image, and batteries will last a lot longer. Digital photography means that the color of light doesn't matter nearly as much as it did with film, but mixed lighting can still cause problems. The LEDs on the Marumi are daylight balanced.

It's reported that St. Paul is trying to take on a whole new light. A block of St. Paul's Iowa Avenue, between Chatsworth and Milton Streets, is lit with light-emitting diode, or LED, streetlights. The lights are brighter and save on energy costs, but some worry about the lighting levels. The city is testing them to see whether they can cut energy use and maintenance costs.
