LEDs Magazine: DOE estimates energy-saving potential of LEDs in general lighting through 2030
The cumulative energy-savings potential from the predicted LED market penetration over the 2010-2030 study period is 2700 TWh, a savings of $250 billion at today?s energy prices or the equivalent of 1800 million metric tons of carbon. This is in comparison to the 1800 TWh of savings estimated in the?2010 report of energy-savings potential. However, several significant changes were made to the study?s methodology and assumptions for the latest report, which are discussed below.The forecast predicts that by 2020, LED lamps and luminaires will have primarily penetrated the commercial and outdoor stationary applications. Proliferation into residential, industrial, commercial and outdoor stationary markets will occur in the 2020-2030 timeframe.
The forecast projects LED lamp and luminaire sales measured in lumen-hours. The analysis indicates that LED lighting in general illumination applications has the potential to represent 36% of sales measured in lumen-hours on the general illumination market by 2020 and 74% of sales by 2030.
According to the Energy Information Administration (EIA), the US consumed 694 TWh of site electricity in 2010 on lighting – approximately 18% of all electricity used. The model demonstrates the total energy consumption for lighting could be reduced by 19% by 2020 and by 46% by 2030 relative to a scenario with no additional LED lamps or luminaires beyond what is installed today (baseline curve in Fig. 1).
By 2030, the annual energy savings from market penetration of LEDs will be approximately 297 TWh, enough electricity to power 24 million homes. At current energy prices, that equates to $30 billion in savings in the year 2030. Assuming the same mix of power stations, these savings, according to the report, would reduce greenhouse gas emissions by 210 million metric tons of carbon in 2030.
New, improved study
The DOE has published this report four times, in 2001, 2003, 2006 and 2010. Several important changes to the 2010 methodology have been implemented. First, the 2010 baseline data now uses the DOE?s recently published?2010 US Lighting Market Characterization (2010 LMC) inventory report. That report showed that 67 million LED lamps and luminaires were installed in the US in 2010, accounting for 0.8% of the total.
FIG. 2.
Secondly, the energy-savings report only considers LED technology and not OLEDs, due to the speculative nature of efficacy projections and price forecasts for OLED luminaires. All energy savings are assumed to be due to LED technology and its improvements.The model includes lighting in residential, commercial, industrial and outdoor stationary applications. The previous reports then grouped lamps by high- and low-CRI application. Now the lamps are grouped by submarket in which different technologies compete, including five categories: general service lamps (medium screw base), reflector lamps (screw base), HID, linear fluorescent and miscellaneous.
Performance, price, lifetime targets
An econometric model used in the analysis relies on assumptions of efficacy, retail price and operating life. These estimates were based on work conducted collaboratively by the DOE and industry experts, including members of the Next Generation Lighting Industry Alliance, an SSL technical working group managed by the National Electrical Manufacturers Association.
LED performance assumptions are based on the DOE?s SSL R&D multiyear program plan (MYPP) and its SSL R&D manufacturing roadmap through 2020. Values for 2030 were extrapolated based on the prevailing trend. LED lamps and luminaires were modeled separately, which was not done in previous studies. The model assumes an average efficacy of 37 lm/W for an LED lamp and 70 lm/W for an LED luminaire in 2010, which is expected to increase to 182 lm/W and 193 lm/W, respectively, in 2020 and 203 lm/W for both product types in 2030.
The model assumes the price (in $/klm) for LED lamps will decrease from $55.16/klm in 2010 to $6.28/klm in 2020 and to $3.34/klm in 2030. For LED luminaires, price is expected to drop from $180.88/klm in 2010 to $23.69/klm in 2020 and to $12.73/klm in 2030.
The report noted that the best LED lamps and indoor luminaires have lifetimes in the 25,000-hour range, while outdoor luminaires have lifetimes of 50,000 hours. These lifetimes are expected to increase to 50,000 hours for LED lamps and indoor luminaires by approximately 2020, and to 75,000 for outdoor luminaires by approximately 2020, when both lifetime estimates hit a plateau.
The model of adoption rate of LED technology considers both first cost of LED lamps and luminaires as well as annual maintenance and operating cost, which together represent life-cycle cost.
By 2030, the energy-savings potential is greatest in the commercial sector, followed by the residential sector, which contribute 37% and 34% to the total energy savings. Outdoor stationary applications make up the next largest sector, at 25% and industrial makes up 4% of the total. A breakdown of forecasted savings in 2030 (Fig. 2) shows that the replacement of linear florescent lamps in commercial applications, HID in outdoor applications and incandescent bulbs in residential applications represent some of the most significant opportunities for energy savings from LED implementation.

LighTimes: Salazar, Chu On Hand at Lighting Ceremony at National Mall
January 31, 2012…At a lighting ceremony put on by the National Park Service and the Trust for the National Mall, Secretary of the Interior Ken Salazar and Secretary of Energy Steven Chu were on hand to celebrate the installation of LED lights on the Mall.? The LED light fixtures, were donated by Osram Sylvania and installed pro bono by Pepco, the electric utility that serves Washington, D.C. The LED fixtures are expected to reduce lighting energy use for the streetlamps by up to 65 percent.
Salazar and Chu were joined by Caroline Cunningham, President of the Trust for the National Mall, Bob Vogel, Superintendent of the National Mall and Memorial Parks and leadership from Osram Sylvania, Pepco, and Siemens Corporation, Sylvania?s parent company.
Osram Sylvania contributed 174 LED bulbs and the retrofit kits for the historic bronze streetlamps that line the Mall from 3rd to 15th streets. The kits replaced the Mall?s high intensity discharge (HID) and compact fluorescent lighting (CFL) with solid-state lighting.
The Department of Energy notes that new LED technology provides a better-lit a atmosphere for visitors after dark, while preserving the architectural integrity of the original fittings.? In addition to being brighter, the technology lasts longer than most conventional light sources.

Optics.Org: Demand for HB-LEDs to grow six-fold in next decade
Global consumption of packaged High Brightness (HB) LEDs in 2011 was $10.77 billion, according to a newly released market survey by?ElectroniCast Consultants. The firm defines HB LEDs as those with a lumens/Watt rating of 30 to 70 lm/W.
The survey reviews the market in 2011 and forecasts what Electronicast believes will happen between 2012 and 2021. The full 887-page market forecast report, along with an extensive database is available for the fee of US$4,200.
In the year 2021, the worldwide consumption value is forecast to reach $69.7 billion. Market forecast data in this study report refers to consumption for a particular calendar year; therefore, this data is not cumulative data. Market data are segmented into the following geographic regions, plus a global summary: America (North, Central and South); EMEA (Europe, Middle Eastern countries, plus Africa); and APAC (Asia Pacific).
And the global HB-LED market is segmented into the following major application categories: Mobile and portable devices, signage and displays, solid-state and general lighting, stationary signals (non-vehicle), automotive/vehicle, consumer-level TV and desktop monitor backlighting, and other/miscellaneous (speciality, medical/science, test/measurement).
Market data for HB-LEDs are also segmented by the following colors (type): multiple-color multiple-chip packaged HB-LEDs; red, orange or yellow single color packaged HB-LED; blue, green, ultraviolet or ?other color? single color packaged HB-LEDs; and white packaged HB-LEDs.
Prices down ? sales up
Decreasing average selling prices is forecast to cause challenging growth patterns in consumption value in some application categories. Because of this, some application categories are forecast for declining consumption values in the second half of the forecast period (2016-2021); however, the sales volumes in all categories are forecast for positive growth throughout the forecast period.
Use of HB-LEDs in mobile and portable devices is forecast to remain a strong segment; however, OLEDs will continue to take market share. The sector is relatively mature and it already has a substantial consumption value in 2012. In terms of consumption value, the use of HB-LEDs in the Automotive/Vehicle category is forecast to multiply by a factor of more than 2-times from 2011 to 2016.
The use of HB-LEDs in stationary (non-vehicle) signals is forecast to increase at an average growth rate of only 5.5 percent from 2011 to 2016; consumption value of HB-LEDs in stationary signals is forecast to decline sharply due to offsetting price declines, as well as market saturation; however, in terms of volume, the segment is forecast for a slight increase during 2016-2021.
General lighting provides the main illumination of an area. In this study, ElectroniCast provides the consumption data for 2011 as well as its market forecast for 2012-2021 of the packaged HB-LEDs used for general lighting stationary applications, including interior and exterior decorative and functional lighting for residential, commercial and government areas.
LEDs are used in both functional and decorative light fixtures, with an advantage of energy savings. Compared to incandescent lighting, LED-based solid-state lighting delivers visible light with reduced heat. In addition, its solid-state nature provides for greater resistance to shock, vibration, and wear, thereby significantly increasing its lifespan.
The consumption value of HB-LEDs in the signage/professional display application is forecast to increase at an average annual rate of 22.1 percent from 2011 to 2016 and then increase at an impressive 35.9 percent per year (2016-2021). Consumption of HB-LEDs in miscellaneous (non-specified) applications is forecast to reach $710 million in 2016, before decreasing during the second half of the forecast period (2016-2021).
The use of HB-LEDs in backlighting of consumer-level TV/desktop monitors is forecast to maintain a strong market share throughout the first half of the forecast period (to 2016), before slipping in market share during the second half of the forecast period (2016-2021), due to saturation in many markets as well as an increase in competition from OLEDs.
Also, the number of white packaged light emitting diodes require in the back lighting unit in the consumer-level LCD-TV and desktop monitor sector will decline, due to increased luminous efficacy and expected improvements in supporting optics (components and packaging).
Interview with Electronicast
High Brightness LED global market sharesoptics.org Does Electronicast foresee a significant switch in both manufacture and consumption of HB LEDs from the West to the East i.e. from the Americas and Europe to SE Asia and the Far East?
Theresa Hosking, VP Marketing, ElectroniCast Consultants Consumption in the American region ? including South, Central and North America ? is forecast to expand in value from $3.88 billion in 2011 to $24.73 billion in 2021. The Europe, Middle East and African region held a 20.2 percent share of global HB-LED consumption value in 2011; EMEA?s relative market share is forecast to increase by 2021, as the region grows at the fastest pace between 2016-2021.
In 2011, the average selling price for HB-LEDs consumed in the American region was 9.6% higher than in the APAC region. In the EMEA region the ASPs, based on consumption, were 7.6% higher in 2011 than in the APAC region.
o.o. Do you expect further legal attempts by Western regulating and governmental agencies to protect the Western-based LED/OLED businesses?
Electronicast We did not forecast future legal attempts by the regulating and governmental agencies; however, we are projecting that one of the major market dynamics and drivers for the use of HB-LEDs will be the continued financial support, including subsidies and incentives, and energy efficiency legislation, regulations and standards by the regulating and governmental agencies, which tend to benefit LED-based illumination.
o.o. Can you comment on the value of your 10-year forecast in such a volatile market and global economy, considering: the likely emergence of LEDs / OLEDs with significantly higher efficiency and more stringent energy and recycling legislation.
Electronicast The length of time of the product planning cycle for an LED-based lighting product from the idea-stage (R&D) through the concept-stage (prototype) to the innovation (new product) can take up to seven years. Therefore five-year forecasts and 10-year forecasts, which quantify the consumption of such products, are vital for developers in the strategic planning process. Developing a product-line without the benefit of independent market projections is not acceptable in terms of best practices.
The future market for a particular type of HB-LED consumed in selected applications depends on a number of factors, including: user equipment demand, energy efficiency requirements and government regulations, future-proofing, the progress of the [wider] economy and investment community, product life cycles, and possible competing technologies.
ElectroniCast analysts forecast the growth rates in HB-LED quantity use in each application, along with price trends, based on competitive, economic and technology forecast trends, and apply these to derive long term forecasts. The concluding usage growth rate forecasts depend heavily on analysis of overall end user trends toward device usage and economic payback.

LEDs Magazine: DOE releases status report on US lighting market
A detailed report has been published recently by the US Department of Energy (DOE), which indicates an overall trend toward higher average system efficacy of installed lighting in the US from 45 lm/W in 2001 to 58 lm/W in 2010 (Fig. 1).This 29% boost in system efficacy is due mainly to the replacement of incandescent bulbs with compact fluorescent lamps (CFLs) in residential applications, and to the replacement of T12 fluorescent lamps with T8 and T5 fluorescent lamps in commercial and industrial sectors.
The efficacies of each of the sectors shows that residential is the sector most in need of improvement with an average efficacy of 19 lm/W, significantly below the other three sectors, which have average efficacies at or above 70 lm/W. The improvement in industrial and outdoor sector efficacies is attributed to a migration from mercury-vapor lamps to metal-halide lamps.
At the same time, new construction has led to an overall 14% increase in the total number of lamps installed in the US. The total number of lamps installed increased from 7 billion in 2001 to 8 billion in 2010, largely in the residential sector. The increased number reflects an increased number of residences but also a trend toward larger homes that require more lamps.
Fig. 2. Electricy usage
The?2010 US Lighting Market Characterization report states that lighting accounts for 700 TWh, or 19% of the country?s energy use (Fig. 2). The commercial sector consumes nearly half of the total (349 TWh), which is largely dominated by fluorescent lighting.Although the residential sector (175 TWh) contained far more installed lamps, most of them incandescent, these lamps experience less daily use, on average, than commercial-sector lamps.
It’s worth noting that LEDs barely register on the chart of total electricity consumption in Fig. 2.

LEDs Magazine: Energy Star Lamps V 1.0 Specification Discussed
January 3, 2012…The 2011 calender year has brought significant changes to Energy Star. On October 21, the EPA released Energy Star Draft 1 of the Lamps V 1.0 specification. The new specification merged the previous specifications into a technology neutral specification to replace the existing specifications for CFLs, Integral LED Lamps, and GU24-based fluorescent lamps.
The EPA sought comment for the specification. The comment period was closed 9 December 2011. On 30 November 2011, the EPA hosted a roundtable discussion and Webinar about the draft specification in which more than 50 stake holders attended and more than 100 participated by phone. The EPA gave partners and stake holders the opportunity to provide feedback to be considered in subsequent drafts. The EPA has made the presentations and audio recordings available at:?www.energystar.gov/lamps.

LEDs Magazine: DOE report on ornamental post-top LED street lights proves disappointing
To allow for apples-to-apples economic comparison, the pricing and input power of the LED products had to be scaled proportionately to represent hypothetical products which could match light levels from the HPS fixtures. Energy used by three of the scaled-up LED systems ranged from 63-90% of the baseline HPS. The fourth product would actually require an increase in energy use by 15%. None of the products would represent cost-effective alternatives to HPS.
In response to recent industry developments, the study also investigated the relative significance of mesopic multipliers offered in the new IES Lighting Handbook and the lumen maintenance extrapolation methodology offered in the new IES TM-21.
This pilot project is the first in a series conducted by the DOE Municipal Solid-State Street Lighting Consortium, which serves as an objective resource for LED product evaluation and a repository for valuable field experience and data. The data generated from this project may be useful to standards groups, manufacturers, and those considering retrofits to LED.

LighTimes: LEDs Make Simulated Sky Ceiling
January 5, 2012…The Fraunhofer Institute for Industrial Engineering IAO has developed a ceiling display that simulates a semi-cloudy blue sky. The luminous ceiling extends across the entire room. The dynamic display simulates passing clouds in the sky, like being out doors.
The innovative luminous ceiling was developed by the Fraunhofer researchers in close collaboration with their partners at LEiDs GmbH. It consists of 50cm by 50cm tiles.??Each tile comprises an LED board with 288 light emitting diodes (LEDs),? stated Dr. Matthias Bues, head of department at the IAO.??The board is mounted on the ceiling. A diffuser film in matt white is attached approximately 30cm beneath the LEDs and ensures that the individual points of light are not perceived as such. This diffuser film creates homogenous lighting that illuminates the room throughout.?
The researchers use a combination of red, blue, green and white LEDs in order to produce the full light spectrum. This combination makes it possible to generate more than 16 million hues. What?s more, the white LEDs are more energy efficient than the colored lights, which keeps the energy costs to a minimum.

The company’s have already committed to the standards and will probably be able to exert pressure on the companies who don’t.
The lighting companies have already switched much of their emphasis from incandecent to LEDs and CFLs. Stores will likely choose to follow the law, but there will likely be some holdouts who continue to purchase and sell incandescent bulbs beyond their existing stock for some time.

LEDs Magazine: Europe initiates public consultation on LED lighting
The European Commission has published a?Green Paper on LED- and OLED-based solid-state lighting (SSL) entitled “Lighting the Future: Accelerating the Deployment of Innovative Lighting Technologies.”
The Green Paper proposes a number of new Europe-wide policy initiatives that are intended to accelerate the wide deployment of SSL. The document also encourages public debate in Europe involving all interested parties.
The Green Paper?s publication also launches a?public consultation period, which is open now and ends onFebruary 29, 2012.The Commission is seeking the views of all interested individuals and organizations on the relevant issues involved by collecting replies on specific questions set out in the Green Paper.
The Green Paper is part of the Digital Agenda for Europe initiative, under the Europe 2020 Strategy for smart, sustainable and inclusive growth. The Green Paper was one of several European initiatives discussed at?Strategies in Light Europe 2010. Two or three large-scale?demonstration projects are expected to be announced soon.
SSL in Europe
The EC believes that, while Europe?s SSL industry is both large and ?world-class?, SSL market uptake is slow in Europe, and SSL-related research, innovation and cooperative activities are fragmented. In this respect, Europe compares poorly with the USA and various countries in Asia.
This situation indicates a need for immediate action at a European level. First, the Green Paper addresses policies targeting European users (consumers, professional users and public procurers) that will help to overcome existing challenges and promote wider market uptake. This includes raising awareness of, and demonstrating, the benefits of SSL, as well as proposing initiatives to prevent early market failure.
On the supply side, the Green Paper proposes policies that ?foster the competitiveness and global leadership? of the European lighting industry. This will, says the EC, contribute to the creation of growth and jobs in Europe.
The public consultation invites participants to answer a series of questions (12 in total) included within the Green Paper. These include:
? What can Member States do to reinforce the market surveillance of product performance and safety in the area of SSL lighting products?
? Which specific measures would you propose for accelerating SSL uptake?
? Which other actions could be taken by industry to reinforce sustainable SSL manufacturing capacity in Europe?
The?public consultation web-page also contain two background documents that can be downloaded. One is entitled ?Energy-Efficient Lighting and Displays: Technologies and Applications? while the second is a report on LED projects and economic test cases in Europe.
LEDs Magazine: US Congress is poised to weaken light-bulb efficiency legislation
The light-bulb-specific activity comes just weeks before the first stage of the regulations would impact the manufacture of 100W incandescent lamps for sale in the US. The Democratic and Republican parties are using the so-called omnibus spending bill, passage of which is necessary to keep the US government funded and functioning into 2012, to advance partisan initiatives. Many Republicans, especially in the radical Tea Party faction, have previously sought and failed to?overturn the light-bulb legislation despite the fact that it was enacted under Republican President George W. Bush.
The Republican-sought riders attacked a number of environmental initiatives, although President Obama and Democratic leaders have worked to limit the environmental impact. The rider eliminating lamp-efficiency regulations remains in the bill at this time. Frances Beinecke, president of the Natural Resources Defense Council, said, “Unfortunately, the bill still contains some damaging riders, including one that will weaken air-pollution controls in the Arctic and another that will block funding to enforce new light-bulb-efficiency standards that were signed into law by George W. Bush.”
The Hill website on its?E2 Wire energy- and environment-focused blog reported Thursday night that both the US House of Representatives and Senate tentatively agreed to a $1 trillion spending bill that?blocks the Energy Department light-bulb-efficiency standards.
In actuality, according to NEMA, it is only the funding for enforcement that is impacted. “Our view is that the standards are still in effect,” said Joseph Higbee, director of marketing communications at NEMA. “The standards are the law and the manufacturers will follow the law.”
The US House will vote on the bill on Friday, December 16. The US Senate will likely vote on the bill on either Saturday or Sunday. Ironically the more controversial part of the bill is an extension of middle- and lower-class tax benefits, but partisanship politics invariably intertwines unrelated measures that should ideally be handled independently. As mentioned earlier, the Republicans failed this past summer to explicitly repeal the 2007 bill.
The legislation will initially impact lamps with 1700-lm output (typical of 100W-incandescent lamps) beginning in January, requiring 30% more efficiency. Incandescent lamps would not likely meet those guidelines, making LED-based solid-state lighting (SSL) or compact-fluorescent lamps (CFLs) the primary consumer choice on store shelves.
It remains to be seen just what type of impact the rider may have. Even if the rider truly blocked the prior legislation, lighting manufacturers and retailers have been preparing for years for the change. Presumably the supply chain is poised to predominantly sell the more efficient lamps.
Indeed the Republican-led last-grasp effort to diminish the impact of the legislation could cost companies heavily. “Manufacturers have invested millions of dollars in meeting the regulations,” said NEMA’s Higbee.
Higbee correctly points out that the manufacturers have developed hybrid incandescent/halogen lamps that meet the new standards, as well as LED and CFL lamps. That is one reason that Higbee said, “We [NEMA] were opposed to the rider.”
Higbee also believes that any delay in enforcement is bad for the lighting industry. He said, “It brings regulatory uncertainty to the industry.” About the Author Maury Wright is a Senior Technical Editor with?LEDs Magazine.
LighTimes: Traditional Incandescent Bulbs Get Nine Month Reprieve
December 19, 2011…Inside the $1 trillion, 1,200 page spending bill is a provision that eliminates funding for implementation or enforcement of the incandescent bulb ban during the 2012 fiscal year. Specifically the bill eliminates funding for Sec 430.32(x) of Title 10 of the Code of Federal Regulations (which covers the general service incandescent lamps, ie A-lamps) and no funding for implementation or enforcement of efficiency standards in the tables in 325(i)(1)(B) of the Energy Policy and Conservation Act with respect to BPAR, BR and ER incandescent reflector lamps during fiscal 2012.
Because the provision is integral to the 2012 appropriations bill, the ban on enforcement would either have to be renewed or the efficiency standards revoked. Otherwise, enforcement of the efficiency standards could start as soon as October 2012.
The bulb ban was one of the sticking points in the bipartisan debates. Republicans wanted to eliminate the bulb ban for some time, reasoning that the ban would force citizens to spend more money on lighting in these difficult economic times. The Republicans were able to tack on the provision, which was approved in Congress.

LighTimes: Frost and Sullivan Projects that Indian LED Lighting Market Will Grow at a CAGR of 45.53 Percent Till 2015
December 13, 2011…&Frost and Sullivan estimates that in India, the LED lighting market is expected to grow at a compound annual growth rate of 45.53 percent till 2015. According to Frost and Sullivan, the fledgling LED lighting industry in India had total revenues of only USD$ 73.3 million. However, massive increases are expected in the industry over the coming years. The growth is attributed to short-term drivers including street light applications and the railway sector. The company says that over 60 percent of the total demand in 2012 will be attributed to these two applications.
Frost Sullivan asserts that LED lighting is expected to grow in India significantly in the future, replacing traditional lighting technologies, but its penetration largely depends on standardization, government support, awareness, and affordability. Frost and Sullivan point outs that LED lighting installations require more complicated designs, spanning optical, thermal, and electronics domains. Furthermore, LED lamps continue to be quite expensive compared to conventional lamps; they rely on imports, as current economies of scale prevent indigenous manufacturing. Frost and Sullivan says that absence of uniform standards for different applications is also restraining LED adoption and is paving the way for sub-standard cheaper imports to flood the market.
World of Photonics: OLEDS with dramatic growth
The innovation in technology and mass production volume are expected to cause a decline in OLED prices. Industry experts expect a huge decline in OLED prices once they are being produced in certain volumes. OLED manufactures across the globe are involved in the research and development (R&D) and expansion of their production line, which will help in attaining economies of scale and reducing prices. The unique features of OLED, such as weight, flexibility, color tunability, low power consumption and durability; show the competitiveness of this technology and its edge over others. OLEDs are also expected to penetrate into the non-lighting market with niche applications due to novel form factors.

LighTimes: Price Gap of LED Backlit vrs. CCFL-Backlit Displays Reemerges as Adoption of LED-Backlit TVs Slows
November 22, 2011…During the Q2 of 2011, the price gap between LED and CCFL-backlit monitors has been reduced virtually zero in models under 22 inches. For models above 24 inches, the gap is at 5 percent, according to a Digitimes?article. According to the article, the market has been experiencing the resurfacing of the price gap. Digitimes cites industry sources who optimistically predicted that the price gap will not affect the penetration rate of LED-backlit monitors because it has become the mainstream.
LED TV sales did not pick up as expected in 2011. This reportedly allowed the reemergence of CCFL-backlit products to the market with lower prices. However, the price of LED-backlit models has still reportedly been decreasing. For example the article cited industry sources who forecast that the price gap between LED- and CCFL-backlit models in the 32-inch size will narrow to less than US$10 in 2011.
The article says that LED-backlit monitors have successfully become the mainstream. The publication says that by the end of the 2011 year the penetration rate is expected to be 70-80%, and the average penetration of the whole year is expected to be around 50-60%. The cited Industry sources pointed out the price of CCFL panels cannot fall lower because there is limited space of gross margin for contraction. However, LED-backlit models still have room for price contraction.
LEDs Magazine: DOE municipal consortium publishes LED street-lighting guidelines
The first draft of the Model Specification was?posted for review in April and the revised specification takes into account feedback from the street-lighting consortium members and the wider community.
The Model Specification available at?www.ssl.energy.gov/specification.html is designed specifically for LED lighting products, which can substantially reduce maintenance costs while improving roadway visibility. There are two guidelines available: the System Specification option for municipalities (Appendix A), which is designed to maximize application efficiency and incorporates site characteristics such as pole spacing and mounting height; and the Material Specification option for utilities (Appendix B), which emphasizes luminaire efficiency and does not consider site characteristics.
The flexible format of the guideline allows users to modify default values to fit their local design criteria, which typically vary from city to city, and even from application to application within a given city.
?Converting our nation?s streetlights to LED technology could make a substantial dent in our energy consumption while also improving quality of illumination ? but only if the right choices are made,? said Consortium Director Edward Smalley of Seattle City Light. ?The new specification will help cities, utilities, and others make better choices.?
The DOE created the Consortium last year to inform and harmonize the efforts of the many cities that are evaluating LED street lighting products, often spurred on by block grants and energy mandates. The model specification was developed by consortium members, with feedback from a manufacturers? working group that included Acuity Brands, BetaLED/Ruud Lighting, Cooper, GE Lighting Solutions, Hubbell, LED Roadway Lighting, Leotek, Lighting Science Group, Osram Sylvania, Philips Hadco, Philips Lumileds, and Philips Roadway Lighting. This input is designed to ensure that RFPs based on the specification will result in submissions from multiple manufacturers.
The specification is a ?living document? that will be adapted as needed. To learn more about the consortium, visit?www.ssl.energy.gov/specification.html. About the Author Laura Peters is a Senior Technical Editor with?LEDs Magazine.
