Acuity acquires Renaissance Lighting and intellectual property
Acuity Brands extends its prior investment in Renaissance acquiring the remaining shares and makes a separate acquisition of intellectual property.
Acuity Brands expanded its minority stake in Renaissance Lighting acquiring the remaining outstanding capital stock for an undisclosed cash payment. The deal gives Acuity outright ownership of Renaissance’s luminaire line and extensive intellectual property portfolio related to LED-based optical technology. Acuity also announced a separate intellectual property acquisition including patents that had been exclusively licensed to Renaissance.
Acuity had previously invested $9.1 million in Renaissance and received a license to certain intellectual property including the Constructive Occlusion optical system that is used in the Gotham (an Acuity Brand) Ecos downlight luminaire family. Now Acuity will have full access to Renaissance’s LED-based solid-state lighting (SSL) portfolio.
“The acquisition of Renaissance and the purchase of related intellectual property support the Company’s strategy to deliver superior, technologically-advanced lighting solutions,” said Vernon J. Nagel, Chairman, President, and Chief Executive Officer of Acuity Brands. “This acquisition will extend our innovation capabilities in solid-state lighting and controls, enabling Acuity Brands to continue to deliver leading-edge lighting solutions to the market.”
Acuity did not reveal the name of the company from which it acquired the intellectual property that had been previously licensed to Renaissance. It did say that the acquisition would add to its capabilities in the sensor and adaptive controls area.
The announcement of the acquisition didn’t specify how Renaissance would be integrated into Accuity Brands, but it will likely join the roster of individual brands that live under the Acuity Brands Lighting banner. Presently, that roster includes Lithonia Lighting, Peerless, American Electric Lighting, Gotham, Roam and several more.
“The merger into Acuity Brands is a tremendous opportunity to broaden the impact of Renaissance’s technology as it is showcased in Acuity Brands’ expansive lighting and controls portfolio,” said Barry Weinbaum, Chief Executive Officer of Renaissance Lighting. “Since its inception in 2005, Renaissance has amassed a high-caliber team with exceptional vision about the future of lighting and has developed a patent portfolio to foster the realization of that vision.”
DOE plans consumer-education initiative on energy-saving lighting
The DOE will work with leaders in the retail and manufacturing segments to educate consumers on green lighting options including LED-based SSL.
The US Department of Energy (DOE) used its SSL Market Introduction Workshop in Philadelphia as a venue to preview a new consumer-education campaign to promote green lighting options. The DOE will partner with GE, Philips, Cree, Osram Sylvania, Home Depot, Costco Wholesale, and Grainger to promote LED-based solid-state lighting (SSL) and other energy-saving lighting options.
The DOE is planning the initiative to coincide with upcoming changes in light-bulb regulation. The Energy Independence and Security Act of 2007 will begin to phase out incandescent bulbs in 2012 – beginning with the 100W lamp and then continuing with lower wattage bulbs on a progressive basis over a two-year period.
According to the DOE press release, “The ultimate effect of phasing out inefficient light sources will be significant national energy savings and a shrunken carbon footprint. However, without an effective consumer education process, these new performance levels could cause considerable confusion.”
The point that the DOE is making is that consumers will need to understand a new figure of merit in place of wattage as an indicator of light output. Indeed wattage has never been a direct measure of light output and new products such as SSL replacement lamps will user a fraction of the wattage or power used by incandescent lamps.
The DOE plans to work with the lighting industry to educate the public on lumens as a measure of light output. The new campaign will also seek to define other benefits of new lighting technologies including for instance the long life promised by SSL.
Expect more details on the education campaign in the coming months. The DOE will formally launch the initiative this fall. It expects other partners to join what’s an impressive group of brand names from both the retail market and the component and lighting manufacturing segment.
Department of Energy Finishes Largest Zero-Energy Building in US Read more: Department of Energy Finishes Largest Zero-Energy Building in US
Walking the walk is key when playing the environmental game, which is why we’re thrilled to report that the United States Department of Energy has completed their new zero-energy research building in Colorado. It clocks in at 222,000 square feet and is the largest zero-energy building in the United States. Boasting 50% less energy usage than a conventional building of its size and a huge array of on-site solar panels, the new Research Support Facility is able to produce all the energy it needs to function without borrowing from the grid. The US government certainly seems to be leading by example with this passive beauty.
The Research Support Facility is located on the Golden, Colorado campus of the National Renewable Energy Laboratory. It will officially open in late August and it will be the working home of 800 federal employees. The building employs techniques new and old to reach its zero-energy status, many of which are hundreds of years old and help the building make the best of natural light from the sun as well as use the earth below it to help heat and cool the building.
Typical office buildings use as much as 30% of their energy expenditure on lighting – not so with the Research Support Facility. The entire east-to-west facing facade is made of as much glass as possible and brings light to all of the building’s interior spaces. It is also outfitted with a smart lighting system which sends employees an on screen message on their computer monitor telling them when to open their blinds. Much of the construction material in the building is recycled including reclaimed steel natural gas pipes that are being used as structural columns. The DOE is hoping that this new building achieves a LEED Platinum rating for all of its green bells and whistles, and it looks like they have a great shot.
Navigating uncharted waters: new challenges in specifying LED luminaire lifetime
Understanding and quantifying the behavior of a single LED, and calculating how this will affect a system with multiple LEDs, are crucial if lighting companies are to set their system warranty level correctly and assess the cost of failures potentially occurring within the warranty period.
Power LED manufacturers claim many advantages for their products over traditional light sources; one is their presumed ultra-long life. In applications that cannot tolerate failure, or where maintenance and repair are difficult or costly, long operating lifetime and extended maintenance cycles are attractive, even when balanced against relatively high purchase costs.
Luminaire manufacturers, and lighting designers and specifiers, have generally been reassured by the claims from LED manufacturers that their devices will typically operate for 50,000 hours. But in fact, the claims of long operating life for LEDs, as for any component, only apply under certain conditions. What is more, LEDs can and do fail in rare cases

Why Are LED Bulbs Better?
The operational life of current white LED lamps is over 100,000 hours. This is 11 years of continuous operation, or 22 years of 50% operation. The long operational life of an led lamp is a huge contrast to the average life of an standard incandescent bulb, which is approximately less than 5000 hours. If the lighting device needs to be embedded into a very inaccessible place, using LEDs would virtually eliminate the need for routine bulb replacement, as well as save energy costs for years to come!
There is no comparison between the cost of LED lights vs. the traditional incandescent options. With incandescent bulbs, the true cost of the bulb is the cost of replacement bulbs and the labor expense and time needed to replace them. These are significant factors, especially where there are a large number of installed bulbs. For office buildings and skyscrapers, maintenance costs to replace bulbs can be enormous. These issues can all be virtually eliminated with the LED option.
The key strength of LED lighting is reduced power consumption. When designed properly, an LED circuit will approach 80% efficiency, which means 80% of the electrical energy is converted to light energy. The remaining 20% is lost as heat energy. Compare that with incandescent bulbs which operate at about 20% efficiency (80% of the electrical energy is lost as heat). In real money terms, if a 100 Watt incandescent bulb is used for 1 year, with an electrical cost of 10 cents/kilowatt hour, $88 will be spent on electricity costs. Of the $88 expense, $70 will have been used to heat the room, not light the room. If an 80% efficient LED system had been used, the electricity cost would be $23 per year – there would be a cost savings of $65 on electricity during the year. Realistically the cost savings would be higher as most incandescent light bulbs blow out within a year and require replacements whereas LED light bulbs can be used easily for a decade without burning out.
Conclusive Test Results Confirm PolyBrite International’s Borealis Streetlight Energy Savings
February 25, 2010 –PolyBrite International, Inc. developer of Borealis LED (Light Emitting
Diode) lamps and lighting systems announced today that The City of Naperville has concluded their 6 month LED streetlight testing period with up to 60% savings in energy usage. Seven 120 watt Borealis LED streetlights with a like number of 350 watt HPS (High Pressure Sodium) streetlights were monitored from June 2009 through January 2010. The Borealis LED streetlights on loan from PolyBrite International were tested along the south side of Diehl Road between Country Club Boulevard and Fairway Drive.
“The successful Borealis LED streetlight pilot test has saved the City of Naperville in electricity use, in turn
saving tax payer dollars,” said Carl Scianna, President and CEO of PolyBrite International. Mr. Scianna further noted, “The test concludes that Borealis LED streetlights consumed a remarkable average of 57.6% less energy than the HPS streetlights. The goal is to replace all public lighting with LEDs to significantly reduce electricity use and green house gas emissions…a win-win situation for our city budgets and for the environment.”
PolyBrite’s patented LED technology, used in all Borealis lamps and lighting systems, will reduce the city’s
operating costs, including lower energy usage and reduced maintenance and bulb replacement. The City of
Naperville’s cost saving calculations project an annual GHG (green house gas) savings by 2015 to be 4,739 metric tons of CO2e (Carbon dioxide equivalent) per year and an annual financial savings, by 2015, of at least $500,000 per year once all the streetlights and traffic signal are converted to LED. These estimates are based on a conservative electricity rate and increases in energy costs would result in higher cost savings.
Borealis LED streetlights produce a sharp, pure color without glare and feature an instant “on” with no cold
starting as compared to HPS street lights, which typically take several minutes to get to full brightness. Motion sensors and lighting controls can also be used with Borealis LED lighting since they can be turned on and off instantly. Furthermore, Borealis LED streetlights are better equipped to withstand extreme hot and cold temperatures and provide more control over what is illuminated, thus reducing light pollution making it an ideal solution for public lighting.
The City of Naperville requested public input and approval of the test installations. The response from the
community has been extremely positive.
Analyst questions LED backlight technology but still sees growth market
Posted by LED Larry in Green Tip, LED, Lighting, New LED Technology on March 9th, 2010
Steve Ohr discussed LED TV backlighting in an APEC Consumer session questioning the price and advantages of the technology while stating that even a bearish outlook promises growth.
The APEC conference featured a series of Special Presentations focused on application areas this year, and the lead session in the consumer space focused on LED backlighting for LCD TVs. Gartner Research Director Steve Ohr presented “The promise for LED backlights in consumer TVs” and questioned just how quickly LEDs will penetrate the application, but still offered a positive market outlook.
Ohr started the presentation stating, “I thought LEDs would be too expensive to use as backlights.” But Ohr noted that consumers seem to be buying the LED sets despite the price premium – and in many cases without a discernible difference in picture quality. Ohr questioned whether the edge-lit sets offer any real improvement in image quality relative to fluorescent-lit sets.
While Ohr noted that some analysts and the TV manufacturers are predicting 50% market penetration in 2010, he takes a much more conservative view. Ohr sees 50% penetration by 2013, but notes that bearish outlook still results in a $2 billion white LED opportunity in 2013
Ohr isn’t alone questioning some of the bullish forecasts. Strategies Unlimited’s Bob Steele also questioned some of the high market projections two weeks ago at the Strategies in Light conference. In his annual market forecast presentation, Steele noted that some analysts are projecting that 39 million LED-based TVs will ship in 2010 while he believes 22 million is a more reasonable projection.
Despite his analysis of the financials and questions about the advantages of LEDs in edge-lit configurations, Ohr said signs are pointing potentially to a more rapid adoption of LEDs. He stated, “Promotion of LED backlights may result in high consumer acceptance despite the higher price.”
Ohr also noted that there are signs in the semiconductor space that those companies see a more rapid transition than most expected previously. He noted that NXP had discontinued development of a new fluorescent driver IC. And he displayed a slide of a Marvell fluorescent driver data sheet with discontinued stamped across the sheet.
Ohr concluded stating, “We need $0.05 by 2013.” He questions whether the LED industry can deliver components at that price both because of the manufacturing and packaging cost, and the need to test and bin the products for intensity and color.
