Philips Lumileds Luxeon Rebel ES delivers 300+ lumens for outdoor lighting
Posted by LED Larry in Uncategorized on August 9th, 2010
A new addition to the Luxeon Rebel family, the new ES model outputs more than 300 lumens at 1A of drive current boosting efficacy for outdoor SSL.
Philips Lumileds has added to its Luxeon Rebel family with a brighter ES model that delivers in excess of 300 lm, and that the company predicts will shorten the payback period for outdoor solid-state lighting (SSL) installations via high efficacy. The Luxeon Rebel ES can deliver 100 lm/W efficacy at the maximum 1A drive current, or luminaire makers can lower the drive current and achieve even greater 125 lm/W efficacy.
Luxeon Rebel ES
Philips is targeting both outdoor applications such as streets, roadways, and tunnels, and industrial high- and low-bay applications with the Luxeon Rebel ES. The LEDs are available with a choice of 4100K and 5650k color correlated temperatures.
Flexibility is a key feature of the Luxeon Rebel ES product because the design allows luminaire makers to optimize products for efficiency or for brightness – or for variable operation based on adaptive controls. “For our customers, system efficiency and costs are significant drivers of LED solution adoption. LUXEON Rebel ES directly addresses these factors and supports our customers’ key objectives,” said Executive Vice President of Sales and Marketing Steve Barlow.
A luminaire optimized for brightness would likely drive the LEDs at the full 1A current, and luminaire makers would need fewer emitters in a fixture to meet the light-output target. Such a design would lower the up-front cost of the luminaire for the buyer thereby reducing the payback period.
The Rebel ES can still deliver in excess of 220 lm at 700mA drive current and in excess of 125 lm at 350 mA drive current. A luminaire maker could optimize for efficacy by using a lower drive current thereby lowering operating cost due to energy consumption – again potentially reducing payback period.
A scenario with adaptive controls might provide the best of both worlds. Indeed recent research and advice from experts recommend controls to dim and extinguish lights automatically based on scenarios such as time of day and activity (see links at right). LEDs are unique among energy-efficient light sources in their broad compatibility with control scenarios.

Real-Life Sci-Fi Discovery of the Day: Scientists Make LED Bulbs From Salmon DNA
Posted by LED Larry in Uncategorized on June 1st, 2010
Where can science fiction possibly go when real-life headlines proclaim that researchers have created LED lightbulbs from salmon DNA? University of Connecticut researchers have added fluorescent dye to salmon DNA and spun the DNA strands into nanofibers to create a brand new material that gives off a bright white light. A LED light is coated with the DNA nanofibers, and voila, a salmon DNA lightbulb is born.
While other scientists have experimented with materials like silica nanoparticles and block copolymers to alter the color of light given off by a LED bulb, salmon DNA has proven most successful. Tuning the light quality from cool white to warm white is just a matter of tweaking the ratio of dyes because, according to researchers, “the DNA fibers orient the dyes in an optimum way for efficient [fluorescence energy transfer] to occur.” So salmon DNA bulbs could overcome at least one hurdle for LEDs–complaints about brightness.
But despite advances in color tuning, University of Connecticut scientists don’t know if their LED bulbs will be cheaper or more energy-efficient than current LED bulbs, which are already more efficient than CFLs and incandescents. And with high-end LED bulbs selling for as much as $80, price will ultimately be the barrier that makes or breaks the success of LEDs in the market.

Solar-Powered Speakers Sing for Renewable Energy
Posted by LED Larry in Uncategorized on May 11th, 2010
Making a statement through music is far from unfamiliar – some of the most powerful messages of our time have been embodied in the most fetching melodies. Taking the wide human reach held within this medium, designer Craig Colorusso has created “Sun Boxes,” an alien field of independently operating, solar-powered speakers, each remitting its own distinct guitar sample. A true marriage of sound and (natural) light, this array of speakers is able to create a glorious composition that attests to the value of solar power in today’s world.
Solely reliant on the sun for its power, the piece changes in synch with nature, offering visitors clear auditory cues into the cycles that occur over a normal day. Each individual is strongly encouraged to wander the field and experience the evolution of music in relation to their position within the space, as well as the intensity of the sunlight – the Sun Boxes will adjust to the light accordingly, and stop playing music when the sun sets. Given the variation in volume and sound, each person is able to create their own experience specific to the path they take within the space.
If you happen to be in Rhyolite, Nevada on May 8th (today!) don’t miss out on the special concert hosted by Important Records, otherwise you can view a windy video of the boxes singing here.

Louisiana Governor Wants to Build New Islands to Ward Off Oil Slick

After the press jumped on the fact that the first attempt to seal the gushing oil leak with an underwater oil containment dome had failed, other noteworthy news receded into the background: Namely, Louisiana Governor Bobby Jindal’s new plan to fight the giant incoming oil slick by dumping dredged materials across the barrier islands off the coast. He says this would strengthen existing islands, and even create brand new ones–but at what cost?

Build Islands, at a Time Like This?
Well, the monetary cost is one thing–the governor said that it would cost “hundreds of millions of dollars” if the plan was given the go ahead. Twelve sites have already been selected for the dredging, and the plans have been sent to the federal government for “quick approval.”
Jindal was optimistic that it would have both short and long term benefits–keeping large swaths of oil from entering Louisiana’s fragile marshlands, and strengthening the barrier islands’ ability to shield the coast from storms. Those islands have been eroding away at an alarming rate–up to 100 feet vanish a year, according to one US Geological Survey report.

He took pains to note that a similar plan has actually been on the drawing board for three years now, and that the oil spill makes the need to approve them even more acute. However, such an operation shouldn’t be taken lightly, as it’s the cost to the environment that should be more carefully considered–it’s got some potentially devastating side effects. And yet, after Jindal announced the plan at a press conference I attended in Venice, LA, attention shifted immediately to the failed containment box, and the plan wasn’t even questioned.
Could be Dredging for Trouble
What Jindal is talking about is essentially a form of what’s commonly referred to as beach nourishment. Which is shiny terminology for shipping in sand or sediment from other locations to drop on threatened or eroding beaches. It’s already a fairly common practice–the federal government already spends some $50-100 million a year “nourishing” beaches in places like California and Virginia. Although in this case, nourishment seems like an understatement–”beach creation” is more apt.

So what’s the problem? Well, just picture what needs to be done to make this happen: First, material needs to be dredged from the selected locations. Which means, tons of mud needs to be dug up form another ecosystem, and this can can be disruptive, even toxic to local wildlife. It can cause a number of problems to the local food chain as well. And then, all that material needs to be dumped on the new location–again disrupting the already existing habitats.
And these barrier islands that Jindal proposes strengthening are indeed home to fragile ecosystems and threatened species like the brown pelican, Louisiana’s state bird. In other words, there could be a bevy of side effects that nobody’s hearing about in this island-creation scheme. Which isn’t to say the plan should be ruled out–just that a careful cost-benefit analysis regarding the effected environment should be carried out before the governor builds a chain of brand new islands.

LED lighting community benefits from ongoing standardization efforts
Posted by LED Larry in Uncategorized on May 6th, 2010
Industry input is providing valuable feedback on the LED lighting standards that have already been put in place in the USA, while further standardization efforts are continuing, writes JIANZHONG JIAO.
With the beginning of a new year and many signs of economic recovery, the LED lighting industry is gaining ground, expanding revenues and working to broaden LED product knowledge and acceptance. The continued market penetration of LED lighting is also providing the industry’s standardization community with valuable, first-hand feedback from users of the technology. This is enabling various organizations to revise existing standards and to continue to develop new standards and to prescribe best practices for developing and using LED lighting products. This article updates progress on standards in the USA since our two-part series published last year (see Links p. 60).
In October 2008, IESNA (the Illuminating Engineering Society of North America) published LM-80, the LED lumen-maintenance testing standard. The purpose of LM-80 is to establish uniform test methods for lumen maintenance of LED light sources including LED packages, arrays and modules. In turn, this allows a comparison of test results from various laboratories. LM-80 lists what data needs to be reported, but it does not specify how the data should be presented, nor does it address the uncertainty of testing equipment and repeatability of testing operations.

Philips has reported strong sales growth in Lighting, with 10% now coming from LED products. Elsewhere, Sharp has a new President of SME, and CRS has reported solid growth.
Posted by LED Larry in Uncategorized on April 29th, 2010
Philips reported first-quarter 2010 sales of EUR 5.7 billion, and EBITA of EUR 504 million. Gerard Kleisterlee, President and CEO of Royal Philips Electronics, said that “growth at Lighting was an impressive 18%, despite a large Professional Luminaires business which is not yet rebounding.”
Philips said that its Lighting sales value was EUR 1.8 billion in the first quarter of 2010, and EUR 6.9 billion in the last 12 months to March 2010.
Philips’ LED sales as a percentage of Lighting sales were 10% over the last twelve months. As shown in the graph, total LED sales were EUR 0.7 billion, split almost equally between packaged LEDs (i.e. products from Philips Lumileds), and LED lamps and luminaires.
The sales value of approx. EUR 350 million ($466 million) for Lumileds for the last 12 months compares with the LED product revenue reported by Cree of $686 million (total figure for the last 4 quareters – see News).
