LEDs Poised to Outshine All Others in $4.4B Lighting Market

Posted in Be Green on September 7th, 2010 by admin – Comments (0)
LAS VEGAS, NV — Dutch giant Royal Philips Electronics took the wraps off its 12-watt EnduraLED light bulb last week at the Lightfair International tradeshow and heralded the latest addition to its EnduraLED line as the “industry’s first” light emitting diodes replacement for the commonly used 60-watt incandescent light bulb, bringing a new measure of energy efficiency to everyday lighting applications at work and in the home.

Osram Sylvania, a subsidiary of Geman powerhouse Siemens AG, countered the following day with its alternative. It introduced attendees at the tradeshow in Las Vegas to the dimmable, mercury-free Sylvania ULTRA LED A-line 12-watt bulb, which its maker calls “the brightest LED replacement” for the traditional 60-watt bulb.

GlacialTechTaiwan-based GlacialTech Inc., a diversified manufacturing firm specializing in cooling, power and lighting, debuted LED products in announcements bracketing Taiwan’s International Lighting Show in March and the Lightfair expo. GlacialTech’s new offerings include a 19-watt portable LED outdoor floodlight and low-power T8 LED tubes.

With a U.S. mandate for more energy efficient lighting taking effect in 2012 and more businesses looking for ways to cut electricity costs, LEDs represent a burgeoning market for the lighting industry — and the rivalry is heating up among companies that want to seize the lion’s share of the sizable spoils.

A new study from Pike Research forecasts that LEDs will account for almost half of a $4.4 billion market for lamps in the commercial, industrial and outdoor stationary sectors by 2020.

Almost 18 percent of global electricity use goes toward lighting, and lighting in the U.S. consumes a fifth of the amount at an annual cost of more than $40 billion. With their ability to produce the same amount of light as traditional bulbs while consuming less energy and lasting far longer, LEDs represent a strong opportunity to cut expenses and reduce electricity use.

Typically, the LED replacements for traditional bulbs are described by their manufacturers as delivering 80 percent energy savings and lasting 25,000 hours, which can be 12 to 25 times longer than the bulbs they are replacing, depending on wattage and the company doing the talking.

Widely used for traffic signals and exit signs, LEDs have yet to break through the cost barrier, which has been the biggest obstacle to market penetration. But that’s expected to change.

Prospective price tags have been reported in the range of $60 for LED retrofits for incandescent 60-watt bulbs and $40 to $50 for LEDs that replace 40-watt bulbs. However, some companies are saying they can beat those prices, at least one already is, and all the firms are jockeying to be the best, brightest and “first” in a number of descriptive categories.

Spotlighting the Green Benefits of LEDs

Posted in Be Green on September 7th, 2010 by admin – Comments (0)

The capability to provide artificial sunlight has dramatically expanded the boundaries of time and space, adding hours to the day when we may see and illuminating where sunlight was unable to penetrate. Since the first humans carried a torch to provide light, heat has been a by-product of producing light.

Traditional electric lights continue to give off more heat than light. An incandescent light bulb uses a paltry 10 percent of its energy to create light. Fluorescent lighting — which has been the green standard in energy efficiency — still wastes nearly half of the electricity it consumes in generating heat. All of this lost energy is significant considering that lighting devours more than a quarter of a typical commercial building’s electricity, as reported by the U.S. Energy Information Administration.

LED, or light emitting diode, fixtures, in comparison, are twice as efficient as fluorescents at converting electricity to light and hence generate very little heat. In addition to improved energy efficiency, LED fixtures are nearly maintenance free and provide high quality of light. They are also dimmable, contain no mercury and tolerate frequent on/off switching without degrading their lifespan.

LED Case Studies

Surgical lightingSince UCSF Medical Center replaced some of its surgical lighting with LED fixtures, doctors and nurses no longer complain about the heat from the light fixtures when performing surgical procedures.

“Previously we had to chill the OR [operating room] to offset the heat generated by the old fixtures,” UCSF Project Manager John Lewis explained. “The new LED lights do not radiate heat and the OR medical staff is comfortable at standard OR temperatures.”

Quality of light is an important issue to adoption of any new lighting technology. Fluorescents were unable to replicate the incandescent bulb’s soft and pleasing glow and disappointed both professional lighting designers and the cube dwellers who toiled under their unnatural glare. LEDs hark back to a more basic light source, the sun. The spectrum and color rendition come closest yet to natural daylight.

An LED is a semiconductor that creates light by releasing energy from electrons. It is frequently referred to as “solid state” or “digital” lighting. Because LED fixtures generate light over an area using thousands of tiny light sources, the fixtures also provide a clear, shadow-free light field that is ideal for task work, whether an accountant, engineer or surgeon.

“The most important criteria for our application is the quality of light. After an early test, we eliminated fluorescent fixtures since fluorescents render colors poorly,” Lewis said. “The medical team found the quality of light provided by the new LED lighting was superior to the existing incandescent lighting.”

While quality of light is important, CFOs, facilities managers and contractors also want to understand the financial benefits of LED fixtures. LED lighting providers emphasize the lower total cost of ownership offered by LED lighting to justify the higher upfront investment.

Much of the savings stems from the improved energy efficiency of LED lighting; up to 70 percent less energy is required to produce light. An added benefit is reducing heat generated, which saves on air conditioning and is noticeable in an operating room, office or data center.

Adding to the cost benefits, LED manufacturers promise an exceptionally long life of 10, 15 or more years. Shifting from disposable to durable lighting eliminates the maintenance costs such as tube and ballast replacement that are standard with fluorescents. Adding to replacement costs is proper disposal of the mercury-based fluorescent tubes.

The Pittsburgh International Airport found the ROI compelling. The airport is installing more than a thousand LED fixtures to cover over a million square feet in its garage (pictured below) and passenger loading and unloading area. The project is believed to be largest single installation of LEDs to date.

Pittsburgh International Airport“Not only does the LED technology reduce our energy costs, it also reduces maintenance,” said JoAnn Jenny, director of communications for Allegheny County Airport Authority.

To further improve ROI, there may be grants and incentives available. Pittsburgh International Airport is taking advantage of a state grant to subsidize installation of LED lighting. With the grant, the pay-back period is cut by half.

Barriers to Adoption

Although LED fixtures offer compelling advantages, there are barriers to adoption. Kim Parsley, a principal for IA Interior Architects, which focuses on sustainable commercial building design, commented, “We are still recommending T5 fluorescents for office and retail spaces. We are cautious about the claims of LED lighting providers and want more case studies. The upfront costs are also off-putting to clients.”

To overcome these early adopter risks, Pittsburgh International Airport first completed a small pilot and then negotiated guarantees from its vendor that the LED fixtures would achieve the advertised light output, efficiency and life expectancy.

LEDs are starting to light standard commercial installations such as offices and retail. Last year, Unilever’s new 400,000-square-foot headquarters (pictured above) used LEDs as primary electric light source. Starbucks also announced last year its plan to retrofit all of its 8,000 company owned stores with LED fixtures and is on-track to roll-out by the end of this year.

Costs are expected to decline with continued improvement in performance. Sandia National Laboratories completed a LED study in 2001 [PDF] to develop a price / performance model. In that taper, Drennen, Haitz and Tsao described LED improvements over the previous thirty years, “In a Moore’s-law-like fashion, [light] per unit has been increasing 30x per decade … Similarly, the cost per unit … has been decreasing 10x per decade.” Improvements in this decade have been consistent with the model.

Implementation Considerations

The most favorable ROIs are for those applications where the lighting is expensive to operate:

  • Energy intensive — Where there is long hours of operation, inefficient technology such as incandescent, halides, or halogens. These applications include garages, hospitals, retail, airports and other transportation hubs, decorative lighting, signage, elevator and restaurants.
  • Costly maintenance — Frequent replacement required. Expensive to replace parts when using traditional fixtures. Examples are signage or outdoor lights.

Even when the ROI satisfies the company’s hurdle rates, other complications may limit the realization of benefits. Since many commercial buildings are leased, if the installation pay-back period is longer than the lease or the tenant does not pay for electricity used, then the tenant has no incentive to make the investment. In these types of scenarios, the tenant and landlord need to negotiate to determine an equitable way to share the costs and benefits of an LED installation.

Next Page: Key considerations when selecting LED providers.

When selecting LED providers, the Department of Energy (DOE) has established a certification program to test and compare various LED products. Since technology advances continue, DOE and other industry groups should be checked periodically for latest insights.

No matter the lighting technology selected, the first step is to reduce the lighting required and then find the most efficient technology for the remainder. Incorporating day lighting reduces the need for artificial lights. Presence detectors and automatic dimming to maintain correct level of light will  eliminate waste.

LEDs Ready for Expansion

The newest use for LEDs, developed by NASA, is to provide light to grow plants for oxygen and food in space. The research from this space application has been transferred to medical uses in the treatment of cancers (see picture, right).NASA LEDs

The nonprofit Light Up the World Foundation is developing and distributing solar LED lighting to poor people in remote areas who still rely on kerosene lamps and wood fires. This old style lighting creates toxic emissions that debilitate the health of those exposed; especially vulnerable are the young and chronically ill. The new LED light is appreciated for its bright illumination as well as its clean and frugal operation.

The quest to provide artificial light has always been about discovering more efficient and safer lighting technology. LED lighting is the next step in that evolution. LEDs have already expanded from niche lighting to standard commercial applications in the last few years. And LED technology is helping to open new frontiers because of its low energy requirements and ability to mimic sunlight.

Posted in Be Green on June 9th, 2010 by admin – Comments (0)

Ledon supplies Langenegg with retrofit LED lamps at cost to help the municipality provide its citizens with the e5 Energy Box

The municipality of Langenegg won an EUR 8,000 prize in an Austria-wide competition called “Austria’s Climate Protection Municipality 2009.” The city will use the funds to provide its citizens with an e5 Energy Box that includes a CFL energy-saving lamp, a switchable plug, an ammeter, and a LEDON led retrofit lamp that Ledon supplied at cost to show support for the energy saving initiative.

“We are at the same time very happy and proud to provide our residents with this e5 Energy Box put together with the help of the prize money. Due to the innovative technology of Ledon LED lamps, it is particularly easy for everyone to contribute one’s share in reducing energy costs and increasing energy efficiency,“ says Georg Moosbrugger, mayor of Langenegg.

The Ledon LED lamp is a 6W replacement for a 40W incandescent lamp. It is 30% more efficient than a CFL and runs 85% more efficient than an incandescent light bulb. Moreover, the LED lamp has no warm up time, is dimmable, and contains no mercury allowing for easy recycling.

The e5 program is dedicated to sustainable energy across the state of Voralberg in Austria. There are 30 different municipalities that participate including Langenegg. Each municipality has its own e5 energy team, and the Langenegg team put together the e5 Energy Box that citizens can pick up for free at the town hall. The team also supplies citizens with information on minimizing energy usage.

The Climate Protection Municipality program is an annual competition sponsored jointly by the Verbund electrical utility, the Austrian Association of Municipalities, and the Federal Ministry of Agriculture, Forestry, Environment and Water Management. The 2010 program is now underway.

Everlight, LG, and Amtran form LED packaging joint venture

Posted in Be Green on June 9th, 2010 by admin – Comments (0)

A new packaging company will target the LED-backlit TV market, with operations based in JiangSu Province, China.

LED-packaging specialists Everlight Electronics has announced its intention to launch a new company focused on LEDs for TV backlights with partners LG Display and Amtran Technology. The joint venture will be capitalized with $30 million, will be based in WeJiang City, JiangSu Province, China, and plans to start mass production by year’s end.

The joint venture will enter the LED backlight market at a time of high demand. Just last week, analyst iSuppli reaffirmed its belief that a shortage of LEDs for TV applications would persist through this year. The firm projects shipment of large-sized LCD panels with LED backlights to reach 276.7 million this year with the number growing to 477.6 million units in 2011 and 817.9 million units by 2014.

Jointly, the three partners in the new venture have shared experience relative to all key aspects of LED-backlit LCD TV technologies. Taiwan-based Everlight has deep experience in LED packaging. Korea-based LG Display is one of the leading manufacturers of thin-film transistor (TFT) LCD panels for TVs, monitors, and notebook computers.

Amtran technology is a contract manufacturer of computer monitors and TVs based in Taipei, Taiwan. The company has a close partnership with Vizio and in fact owns a stake in the company that was the market leader for TVs in the US for 2009.

The companies believe that their shared experience will enable the yet-to-be-named venture to rapidly offer state-of-the art LEDs for the backlight market.

Epistar expands with Huga investment and Win Semiconductor partnership

Posted in Be Green on June 9th, 2010 by admin – Comments (0)

Epistar, already the largest LED chip manufacturer in Taiwan will take a stake in the second largest manufacturer Huga, and GaAs foundry Win Semiconductor will invest as well.

Apparently driven by the ramping demands for LED backlights in LCD TVs, the leading Taiwanese LED chip maker Epistar will invest in and partner with Huga Optotech. Epistar will become Huga’s largest shareholder and in related news gallium arsenide (GaAs) foundry specialist Win Semiconductor will also invest in Huga.

Epistar’s board of directors has approved a plan to issue 78 million new shares that it will exchange for 184.08 million Huga shares. Huga is also issuing 100 million new shares at NT $30 (USD $0.94) to raise additional capital. Epistar will subscribe to 44.79 million of the new shares with a NT $1.5 billion (USD $50 million) cash investment.

The Epistar deal with Huga is scheduled to close July 19. At that time Epistar will hold a 47.88% stake in Huga worth NT $8.6 billion (USD $268 million). Epistar hopes the consolidation will boost capacity and efficiency so it can better serve the escalating TV market.

Win Semiconductor, meanwhile, is expected to buy the remaining new shares issued by Huga according to Taiwan semiconductor news specialist DigiTimes. Win Semiconductor Chairman Dennis Chen is also the current Chairman of Huga.

Epistar has previously been active in the acquisition market. In October 2009 Epistar acquired a 19.3% stake in Tekore Co, and earlier acquired a 40.75% stake in Na Ya Photonics. All of the acquisitions provide Epistar with access to additional MOCVD reactors needed for LED production, but which are currently in short supply.

LED Lighting Penetration to Reach 46% of the Commercial Building Lamp Market by 2020

Posted in Be Green on June 1st, 2010 by admin – Comments (0)

Lighting accounts for about 17.5% of global electricity use and, within the United States, the majority of lighting energy is consumed in commercial buildings. Recent innovations in lighting technologies, particularly the development of solid state lighting using light emitting diodes (LEDs), hold significant long-term potential for energy savings in the commercial building sector.

According to a new report from Pike Research, LED lighting will become an increasingly important segment of the market, and by 2020 it will achieve a 46% penetration of the $4.4 billion U.S. market for lamps in the commercial, industrial, and outdoor stationary sectors.

“LED lighting will reach an inflection point in the next five years,” says managing director Clint Wheelock. “As solid state lighting costs come down and performance increases, LEDs will become a practical option for an increasing number of commercial applications.” Wheelock adds that LEDs are already widely used in traffic signals and exit sign lighting, and Pike Research anticipates that those markets will become saturated within the next few years. The outdoor stationary sector will be the next growth area for LED lighting, followed by retail and office/professional and institutional buildings.

However, despite the strong long-term prospects for LED lighting, Pike Research’s analysis indicates that the category still faces a number of technological and economic hurdles. As a result, while the cost and efficacy of solid state lighting are rapidly improving, it will be a number of years before LEDs lead the commercial lighting market. During this period of transition, fluorescent T8 and T5 lamps, which offer good efficacy and life at very reasonable prices, will overtake incandescent lamps as the leading technology prior to the coming of age for LED lighting products.

Pike Research’s study, “Energy Efficient Lighting for Commercial Markets”, examines the key technology and market trends that are driving the use of LED and other high-efficiency lighting in the Commercial, Industrial, and Outdoor Stationary sectors. The report includes a 10-year forecast for lamp and luminaire sales in the U.S. across 10 different lighting technology categories in seven major building types and application sectors. In addition, the study provides SWOT analyses of 16 key industry players. An Executive Summary of the report is available for free download on the firm’s website.

Pike Research is a market research and consulting firm that provides in-depth analysis of global clean technology markets. The company’s research methodology combines supply-side industry analysis, end-user primary research and demand assessment, and deep examination of technology trends to provide a comprehensive view of the Smart Energy, Clean Transportation, Clean Industry, Corporate Sustainability, and Building Efficiency sectors.

Novaled and Universal Display advance OLED lighting technology

Posted in Be Green on May 24th, 2010 by admin – Comments (0)

OLED lighting technology

Novaled announces a new top-emitting white OLED, while Universal Display receives $4 million from the DOE to build pilot OLED production line

Universal Display will have two years and $4 million to demonstrate the scalability of its UniversalPHOLED technology for the general illumination market, and together with Moser Baer Technologies will build a pilot production line. Novaled, meanwhile has a new top-emitting white OLED technology that is made on a metal substrate, doesn’t require brittle and expensive Indium Tin Oxide (ITO), and is rated for 50,000 hours of life.

Novaled developed the new OLED using its P-doped, Intrinsic, N-doped (PIN) OLED technology that leverages proprietary host and doping materials, and blue fluorescent emitting material from SFC Korea. The company also adds a proprietary light-extraction layer that eliminates color shift and increases efficiency.

The metal substrate in the new PIN-OLED-based design offers improved heat dissipation, mechanical stability, and flexibility, and offers compatibility with roll-to-roll manufacturing techniques.

The new Novaled OLED outputs 30 lm/W with an initial luminance of 1,000 cd/m2. With this achievement Novaled demonstrates once again the robustness and potential of its PIN technology”, says Gildas Sorin, Novaled CEO. “Configurations like top or bottom, inverted or non-inverted organic structures with various emitting materials and metal electrodes bring the proper high performance for each specific market request in the display and lighting domain.”

Universal, meanwhile, is a technology leader in phosphorescent OLED technology and materials and has claimed a 4x energy efficiency advantage over competing technologies. The US Department of Energy (DOE) has invested $4 million in Universal under the American Recovery and Reinvestment Act of 2009 for a program titled “Creation of a U.S. Phosphorescent OLED Lighting Panel Manufacturing Facility.”

Universal will use the funding to prove out the technology, materials, and manufacturability of its UniversalPHOLED technology for commercial lighting. Moser Baer Technologies (US subsidiary of Moser Baer India) will design and build a US-based pilot production facility for Universal.

“This new U.S. DOE program represents a very important step towards the establishment of high-volume manufacturing of white OLED lighting panels in the U.S.,” stated Steven V. Abramson, President and Chief Executive Officer of Universal Display. “We are delighted to have this opportunity to team with Moser Baer Technologies, with its experienced leadership in manufacturing of thin-film, high-volume products. By combining our highly-efficient UniversalPHOLED technology and materials with Moser Baer Technologies’ proprietary manufacturing technology, we believe that the new pilot facility can demonstrate a cost-effective route to high-volume production of energy-efficient and environmentally-friendly white OLED lighting products, which in turn can serve as a basis for new manufacturing investment and job growth in the U.S.”

An LED BFD

Posted in Be Green on May 24th, 2010 by admin – Comments (0)

uture of light is plastic

The future of light is plastic, says Cyberlux.

The company, which specializes in light emitting diodes (LEDs, will come out with prototypes of a new type of white light LEDs in about four months that will cost substantially less to manufacture than conventional LEDs and provide more light at the same time.

In conventional white light LEDs, a semiconductor emits blue light. The blue light passes through the phosphor and becomes white light. The phosphor is thin film on a substrate; the substrate has to be placed in intricate proximity to the semiconductor. Positioning the phosphor is one of the more expensive steps in creating an LED, said Mark Schmidt.

LEDs cost a lot. But they use less energy than conventional lights and come in multiple colors, so you can decorate your house so it looks like Peter Max lives there, as this photo at the Lumileds headquarters shows.

In the coming prototype, the conventional phosphor is replaced with a sheet of polymer, which sort of applies itself into the LED, almost like a layer of shrink wrap. The technology was invented by The University of California Santa Barbara’s Stephen DenBaars, who has been a big advocate of LEDs and Nobel Prize winner Alan Heeger.

Meanwhile, the prototype will have a greater efficiency than conventional LEDs because more photons will get through the phosphor and emerge as white light because of technology from RPI.

Semiconductor vendors show LED focus with new driver ICs at APEC

Posted in Be Green on February 25th, 2010 by admin – Comments (0)

APEC LED-driver-IC announcements highlight PFC and efficiency, along with TRIAC dimming capabilities and single-stage power supplies

The 2010 APEC (Applied Power Electronics Conference and Exposition) kicked off in Palm Springs Monday, and among the early highlights you will find several LED-centric developments. The power-electronics IC community has embraced LED lighting as a key application going forward, and the current trend appears to be more efficiency and power factor correction (PFC).

On Semiconductor, Fairchild Semiconductor, and Infineon have all made news in the LED space. Along with efficiency, other headlines include TRIAC dimming and varying power-supply topologies.

On Semiconductor launched the NCL30000 driver that is mainly used in critical-conduction-mode flyback supply architectures, although it can also support buck topologies. The IC can implement a single power stage working from the AC line, eliminating the need for a DC/DC stage.
On Semiconductor NCL30000

The design includes power factor correction (PFC). In a power supply, PFC circuits control input current to the load attempting to keep voltage and current in phase and to make the load appear purely resistive. A resistive load allows most efficient usage of AC mains power. PFC is expressed as a fraction of unity and the On Semiconductor component achieves a 0.95 rating.

Targeting residential and commercial applications, the NCL30000 also offers the efficiency needed for certifications such as Energy Star. In fact the IC can maintain efficiency even at very light loads and can implement TRIAC dimming to less than 2% of full light output.

Infineon also introduced a dimming capable IC at APEC. The company claims that the ICL8001G achieves 90% overall efficiency and a PFC rating of greater than 0.98. Moreover, the IC maintains efficiency of over 80% across the entire dimming range.

The Infineon IC targets residential applications including 40W to 100W incandescent bulb replacement. The AC-driven IC includes digital soft-start capability to limit in-rush current as well short-circuit, over-voltage, and over-temperature protection.

The Fairchild offerings include the FSEZ1307, FSEZ1317, and FAN103 PWM drivers. All of the products use primary-side regulation (PSR) techniques that don’t require feedback from the secondary side of the supply. The constant-current drivers dissipate only 30 mW of standby power and achieve efficiency levels needed for Energy Star compliance.

Stay tuned for more APEC news later in the week.
