Last year, we featured a nightclub lit entirely by LEDs, but here's an office building that is said to be the first to be lit by 100% LED light. The lighting was provided by the Netherlands-headquartered Royal Philips Electronics. To showcase the potential of LED light, Philips designed the lighting system to be warm and visually comforting. A total 422 LED fixtures were instalLED into the building's false ceilings. The offices are lit with fixtures that incorporate 12-16 high power LEDs, each rated at 2.6 watts. LED spotlights are used to illuminate the corridors.

Technology Review has an update on cheap, energy efficient OLED lighting - Ultra-Efficient Organic LEDs. An organic light-emitting diode (OLED) developed in Germany has the potential to produce the same quality of white light as incandescent bulbs but with power efficiencies considerably better than even fluorescent lighting. The prototype OLED could emerge as an ultra-efficient light source for displays and general lighting, says Sebastian Reineke, who LED the research at the Institute for Applied Photophysics, in Dresden, Germany. The long-term goal is to fabricate the device using conventional low-cost roll-to-roll printing. In recent years, many countries have begun looking to switch from incandescent lighting to compact fluorescent bulbs because the latter are so much more energy efficient. There has also been a lot of interest in using light-emitting diodes (LEDs) for displays and general lighting, again because of the potential energy savings they offer. But with both fluorescent and LED lighting, the quality of white light produced has always left something to be desired. Fluorescent lighting can make people appear unhealthy because less red light is emitted, while most white LEDs on the market today have a bluish quality, making them appear cold.

Earlier today I received an email from the office of Pittsburgh city councilman Bill Peduto announcing an ambitious plan that will reduce Pittsburgh's carbon footprint while saving the city millions in electricity costs. Peduto, who has been the only city legislator to propose green legislation of any sort over the last few years, wants the city to convert all 40,000 of its street lamps to energy efficient LED lighting. The cost of the program will be around $24 million and will be paid using a combination of the annual costs savings and funding from the state's Guaranteed Energy Savings Agreement. Pittsburgh would join cities such as Austin, Raleigh (home LED manufacturer CREE), and Toronto as major cities who have adopted LED lighting on a large scale. According to Peduto, Pittsburgh would be the largest city in the US to roll out a complete conversion to LED lighting. This would be great news for Pittsburgh's green agenda, especially in light of today's Pittsburgh Penguin's press conference, where they announced the 21 year naming rights deal for their new arena, which will be known as the Clean Coal Center.

Fast Company and New Scientist have reports predicting that cheap GaN based LED lights may soon make both ncandescent and compact fluorescent light globes obsolete - Better, Cheaper LEDs Ringing Death Knell of Fluorescent Bulbs. LED lighting has long been viewed as a superior alternative to compact flourescent bulbs. Although flourescents are more electrically efficient than old-fashioned incandescent bulbs, producing them requires a complex procedure that uses a little mercury--a big environmental and health no-no. Indeed many are questioning whether CFLs are actually an environmentally-friendly choice at all.

Light-emitting diodes (LEDs) are better than compact fluorescent bulbs--LEDs use less energy, last longer, and contain no toxic mercury--but for general white-light illumination, they're still far too expensive for mass adoption. Now, researchers at Purdue University have taken a step toward making white LEDs with cheaper materials.

The incandescent lightbulb that wastes 90% of the electricity as heat is dying, we all know that. But a new breakthrough in solid state lighting might also kill compact fluorescent lightbulbs (CFLs) faster than some expected. Scientists at Purdue University have figured out how to manufacture LED solid-state lights on regular metal-coated silicon wafers (more details below). What this means is: much lower costs.

A new way of making LEDs could see household lighting bills reduced by up to 75% within five years. Gallium Nitride (GaN), a man-made semiconductor used to make LEDs (light emitting diodes), emits brilliant light but uses very little electricity. Until now high production costs have made GaN lighting too expensive for wide spread use in homes and offices. However the Cambridge University based Centre for Gallium Nitride has developed a new way of making GaN which could produce LEDs for a tenth of current prices.

Next100 has a report on the introduction of LED street lighting in some sections of San Francisco - Brightening Up San Francisco's Tenderloin. San Francisco's gritty Tenderloin district will shine a little brighter thanks to a new streetlighting program announced today by Mayor Gavin Newsom, the San Francisco Public Utilities Commission and PG&E. Newsom press conf 3-25-09.JPGAt a press conference this morning on Turk St., joined by PG&E's senior vice president for public affairs, Nancy McFadden, Newsom said the city is installing 50 ultra-efficient, energy-saving LED streetlights in the depressed neighborhood, a smart move to enhance public safety while demonstrating environmental leadership and saving money. In addition, city authorities are working with PG&E to evaluate "smart controller" technology that will monitor the performance of individual streetlights, adjust their intensity, and signal when they are about to fail. Flexible controls will give officials to ability to turn selected lights on or off, dim them, or flash them to alert emergency personnel.

Part of creating the ultimate sustainable planet will be our ability to find sustainable energy sources in a variety of means, such as sunlight, water flow, wind, and yes, even rain. We are of course speaking of the kinetic energy which can be harnessed from rain, which up until a few months ago, was not being considered for use in a consumer product... Lightdrops Umbrella This kinetic energy is created from piezoelectric material, which is able to convert mechanical energy into electrical energy. Now, we aren't talking about a whole lot of energy being created here, approximately 1 microwatt to 12 milliwatts per rain droplet. While not much in the large scheme of things, this technology has been put to use in a new LED umbrella calLED Lightdrops, which is able to self power an internal LED light using the rain from which it is protecting its user from.

I wanted to talk to you about the differences in the white LED s. And they also come in different sizes. The numbers that you see before the size is pretty much how big the LED is in millimeters. But keep in mind other sizes that may have come in different applications.

Product review LED Christmas Lights C7 - Energy Efficient

Working in Haiti, Shawn Frayne, a 28-year-old inventor based in Mountain View, Calif., saw the need for small-scale wind power to juice LED lamps and radios in the homes of the poor. Conventional wind turbines don't scale down well-there's too much friction in the gearbox and other components. "With rotary power, there's nothing out there that generates under 50 watts," Frayne says. So he took a new tack, studying the way vibrations caused by the wind LED to the collapse in 1940 of Washington's Tacoma Narrows Bridge (aka Galloping Gertie).

Wall mounted Passive Infrared PIR motion sensor LED lights and energy saving lamps for outdoor and garden areas.

Here's one for the alternative wind power experiments file - a report from BusinessWeek on an interesting design idea, inspired by the Tacoma Narrows Bridge collapse of 1940 - Humdinger's Wind Power Alternative. As an MIT engineering undergraduate visiting the rural fishing village of Petite Anse, Haiti, in 2004, Shawn Frayne hoped to devise a way to convert abundant agricultural waste into cheap fuel. But the budding engineer soon found that the community's mainly poor residents faced an altogether more immediate need. Unconnected to the local power grid, they relied heavily on dirty kerosene lamps, which are not only costly to operate but also unhealthy and dangerous. He decided to devise an alternative-a small, safe, and renewable power generator that could be used to power LED lights and small household electronics, such as radios.
