Some industry experts predict that within 10 years, these lights will deliver more environmental and economic benefits than any other clean technology, including high-voltage power transmission, electric vehicles, smart grids or renewable power.
In North America,LED high bay light account for about 8 percent of the general lighting market, according to a 2012 report on the global LED sector from consultants McKinsey.
The use of these lights in the United States alone has saved 2.6 terawatt hours of power per year, equivalent to the electricity needed to power over 200,000 average U.S. households, according to a 2011 research report prepared by Navigant Consulting Inc for the U.S. Department of Energy.
In China, the world's top energy consumer and carbon emitter, general lighting accounts for 12 percent of annual electricity consumption. About 70 percent of China's electricity is generated from coal.

the customer can quickly test the LED in its desired application
Philips reported a $482 million fourth-quarter net loss, doubling 2011's $218 million loss, and warned that the company will go through a slow start this year. Philips managed to save $635 million at the close of 2012. Van Houten pledged to target $1.48 billion in savings by 2014, according to the Wall Street Journal.
With its “LED Evaluation Kit”, Sharp has developed a new powerful marketing tool for the Mega ZENIGATA which allows customers to easily test the Sharp LEDs for later use in the desired application. The evaluation kits are available for all power output classes of Mega ZENIGATA LEDs (15 W, 25 W, 35 W, 50 W). The “LED Evaluation Kit” includes not only the desired Mega LED ZENIGATA but also all the necessary accessory components, such as mechanically prefabricated heat sinks, thermal paste, and the appropriate power supply, so that the customer can quickly test the LED in its desired application. As technical assistance, each kit comes with a short instruction manual for installation.
This € 14.7 m project was supported by the German Ministry of Education and Research (BMBF) over a three and a half year period and addressed the complete value chain, from primary OLED materials through to OLED-lighting applications. Several of the promising innovations created within the project will now be brought to market by the participants of the So-Light project.
The project partners Novaled, Sensient, University Muenster, Fraunhofer-COMEDD, AIXTRON, LEDON OLED Lighting, Fresnel Optics, HELLA, Siteco, BMG MIS (former AEG MIS) and the University of Paderborn/L-LAB cooperated in a variety of OLED technology areas. These activities created several innovative results related to materials, processes, optical elements and process integration. For some specific applications prototypes have been developed for OLED-signage and speciality applications for markets such as automotive, architectural lighting and transport. The aim of So-Light was to combine as many of the materials and component related results into design studies and prototypes in order to strengthen Germany’s leading role in the growing OLED-market.

the limited adoption of the highest efficacy lamps
Since lamps that meet consumer color quality expectations will provide significantly more energy savings than the limited adoption of the highest efficacy lamps; manufacturers, designers, academics, and LED high bay light utilities strongly recommended that EPA provide some easement for the luminous efficacy targets of high CRI LED Lamps, which are fundamentally more challenging than low CRI products. Specific proposals were submitted to the EPA last week.
“Fundamental physics research shows that there is a ~2% penalty in luminous efficacy per point of CRI. So, going from a CRI of 80, where most LEDs operate, to a CRI of 90, there is a ~20% penalty in lm/W,” said Dr. Shuji Nakamura, Professor of Materials Department and Co-Director for the Solid State Lighting & Energy Center at the University of California, Santa Barbara.
Researchers from Boston University have invented a unique way of using LED lights to transmit location information to mobile devices within buildings.
Researchers Dan Ryan and Aaron Ganick’s start-up, ByteLight, is based entirely around proprietary software that can accurately map the inside of buildings using only LED lighting to transmit location information.

There have only been two larger previous awards
Among the disk makers, Western Digital has been its biggest customer over recent years. Carnegie Mellon had accused Marvell of including technologies—invented by one of its professors and a student—designed to increase the accuracy disk drives read data at high speeds. The university told the court the firm had sold 2.3 billion chips incorporating the disputed inventions between 2003 and 2012.
Marvell had argued both that its chips had not used the university’s tech, and that the patents should never have been awarded in the first place—but the jury disagreed. The damage award has the potential to be the biggest in US patent history. There have only been two larger previous awards, according to law data provider Lex Machina.
In 2007 Microsoft was ordered to pay Lucent Technologies US$1.52 billion in damages over disputed MP3 and MPEG video technologies; and in 2009 Abbot Laboratories was ordered to pay Centocor Ortho Biotech US$1.67 billion for infringing its antibodies biotech patents—however, both judgements were later overturned.
That leaves the recent US$1.05 billion jury award to Apple in its case versus Samsung as the largest outstanding figure—the judge in the case has yet to finalise the sum. However, one expert said it would be some time before the details of the disk drive dispute would be finalised.

The Financial Times believes LED technology is reaching a tipping point
A glut of manufacturing capacity and near-collapse in rare earth metal prices is driving down the cost and hence encouraging the rapid take-up of light-emitting diode (LED) lighting.
LED lights are based on semiconductors and therefore do not require traditional lamp manufacturing expertise. This has opened opportunities for LED chipmakers to challenge the incumbent incandescent light bulb manufacturers such as Philips, Osram and General Electric (GE), who have enjoyed a near-monopoly of the market according to an FT article.
The Financial Times believes LED technology is reaching a tipping point, particularly for the commercial sector, as price declines bring forward the payback time on the initial cost of investment. According to McKinsey, quoted in the article, LEDs are set to account for 41 percent of the overall value of the lighting market in 2016 and 63 percent by 2020, versus 12 percent last year.

The pilot program is intended to showcase the various technology options
The SFPUC says LED fixtures are superior to the existing high-pressure sodium cobra head-style streetlights. They consume 50 percent less energy on average than the conventional streetlights and generally do not require maintenance for up to 20 years.
The technology would allow the lights to be monitored in real time, allowing the SFPUC to detect whether a replacement is needed, respond more quickly to outages and adjust brightness levels remotely, said Charles Sheehan, a spokesman for the agency.
A Dec. 11 SFPUC memo says, “Each pilot project partner will supply 18 LED street lights with integrated controls, supporting equipment and web access to software. In addition to the integration of the LED street lights with the controls, various sensors and video cameras will be tested.”
The pilot program is intended to showcase the various technology options.
Community meetings are planned for January in the test neighborhoods. Those areas include Irving Street between Sixth and 24th avenues, Washington Street between Presidio Avenue and Arguello Boulevard, and Pine Street between Market Street and Grant Avenue.
The pilot is expected to begin in March, with total installation and a Wi-Fi network slated for 2014. The project is estimated to take about a year and a half to complete.

Annual bulb replacements were becoming a significant financial drain in both supply
At its 1,700-megawatt Martins Creek Power Plant north of Easton, Pa., the company recently replaced the antiquated Xenon obstruction lighting system on the facility’s two exhaust stacks with state-of-the-art 270,000 candela LED High-Intensity Strobe systems from Dialight. The retrofit will reduce PPL Generation’s maintenance and energy costs.
Constructed in 1974, the Martins Creek facility consists of two oil/natural gas-fired units with a generation capacity of 850 megawatts each. Twin 600-foot ventilation stacks tower over the facility and its surrounding neighbors, each signaled by the requisite FAA obstruction lighting system.
The existing systems, comprised of two sets of three Xenon strobes at positioned 296 feet and 586 feet, had been in place more than 30 years, since the plant first came online. Annual bulb replacements were becoming a significant financial drain in both supply and manpower costs. In 2010 alone, the Martins Creek plant had to replace 10 out of 12 lamps. The year before, the plant replaced all 12 lamps.
Recognizing the need to upgrade, PPL worked with its electrical and lighting contractor, Fuellgraf Chimney & Tower, to specify a new high-efficiency LED system.

the final stages of renovation with a scheduled inauguration date of February 2013
Insiders emphasize that government regulators should provide clear and consistent LED bulb lumen specifications that precisely match incandescent lumen specifications so that shoddy products will not be able to push quality products out of market.
The PIDA suggests that in addition to providing labels with clear product specifications, manufacturers need to introduce LED bulbs that are much better, in terms of energy efficiency, than CFLs equipped with efficient ballasts.The association feels that purchases of LED bulbs will likely increase if the government includes the bulbs in a labeling system established by the government to rate electrical products according to energy-saving performance.
The lighting system for the final match and six other games in the 2014 FIFA World Cup, as well as the opening and closing ceremonies of the 2016 Olympic Games has been selected: Jornalista Mário Filho Stadium, better known as Maracan? - considered one of the world's best and most classic soccer venues - will offer a much clearer and sharper visual experience for athletes, spectators and television viewers around the globe. A contract between the Rio de Janeiro state government's public works company (Empresa de Obras Públicas, EMOP ); Consórcio Maracan? Rio 2014, a consortium comprised of the Norberto Odebrecht and Andrade Gutierrez construction groups; and GE Lighting, which will supply the system, includes the installation of 396 GE EF2000 floodlights to illuminate the field at the new Maracan?, currently in the final stages of renovation with a scheduled inauguration date of February 2013.

the chip has been designed in particular for infrared illumination applications
Epistar not only respects others’ IP but also protects its proprietary technologies by filing its own patents or by acquisition to strengthen its patent portfolio. This is a demonstration of Epistar’s engineering efforts and capabilities. It also provides Epistar’s customers and partners freedom and a secured position in LED industry.
The infrared chip prototype has achieved a new record with an efficiency of up to 72 percent. At 930 milliwatts from an operating current of 1 amp, its light output under laboratory conditions is 25 percent higher than that of the chips currently available on the market, which means that future infrared LEDs can be made even more energy-efficient. The efficiency was measured at room temperature and at a dc current up to 1 amp. With a wavelength of 850 nanometers the chip has been designed in particular for infrared illumination applications.
The results from the R&D laboratory in Regensburg have created a new milestone. The prototype of a 1 mm2 chip in infrared thin-film chip technology has achieved an efficiency of 72 percent from an operating current of 100 milliamps. This efficiency, known as wall plug efficiency (WPE), indicates the ration of the radiated power to the electrical input power.
The external quantum efficiency (EQE), in other words the probability of creating a photon and its emission from the LED chip per electron, is as high as 67 percent and remains above 64 percent up to an operating current of 1 amp.

the dark spots that form between poles with sodium lamps strung along residential streets
Across North Carolina, the "greener" streetlights are beginning to appear in pilot studies in Charlotte, Raleigh, LED high bay light and Greenville. In November, Asheville began the third and final phase through Progress Energy Carolinas to upgrade LED streetlights on city-maintained roads.
In Fayetteville, PWC installed the first electric streetlight around 1910 on North Cool Spring Street downtown, and more than 40 were added along Hay Street in 1913.
Today, sodium-vapor-powered lights have been ubiquitous across the city for a generation, casting a yellowish glow over streets and sidewalks. Sodium vapor replaced mercury-vapor lights, which were the industry standard in the 1950s and '60s.
But mercury lamps became an environmental liability, and disposing of burned-out mercury bulbs became costly, said Reggie Wallace, interim chief operating officer for PWC's electric system.
He said streetlights with LED fixtures cast white light that spreads out, reducing the dark spots that form between poles with sodium lamps strung along residential streets.

wireless control systems are set to overtake wired control systems in sales
The popularity of wireless lighting control systems is increasing as they are cheaper in construction terms, and easier to set up, as no modification to existing structures is required. Patterns suggest that wireless control systems are set to overtake wired control systems in sales.
Ballasts account for the largest portion of the lighting controls market, and the advent of electronic ballasts and the subsequent LED high bay light dip in price, coupled with their energy efficiency resulted in markets swaying in favour of electronic ballasts.
Currently, Europe is the largest regional lighting controls market worldwide. It is closely followed by the USA, with Asia-Pacific offering the highest growth potential due to an increase in construction activity and mandatory government policies that require the incorporation of green technologies and adherence to various energy efficiency standards.
Speaking to reporters here showcasing Light Next ? an interactive lighting experience centre, Nirupam Sahay, president at Philips Lighting said, the growth drivers from the segment are the decline in LED prices, investment by government in energy efficient lighting systems and the quick return on investment (ROI).

Commercial lighting trade show and conference
The partnership will cover in total some 90 light centers across Africa and South America, the first of which are scheduled for installation in early 2013, will be focused on schools which are closely linked to villages and LED high bay light towns in off-grid or semi-grid areas (this can also include parts of cities).
Some 1.6 billion people worldwide have no access to electricity. For people living near the equator, darkness falls around 7pm all year round, slowing down or completely stopping many vital tasks.
Diego in a strategic move signaling continuing growth for the world’s largest annual architectural and commercial lighting trade show and conference, according to Jeffrey L. Portman, Sr., president and chief operating officer of LFI managing partner AMC, Inc.
The 2016 staging at the San Diego Convention Center marks the San Diego premiere for LFI, which is produced alternately annually in large east- and west-coast venues. The San Diego location follows LFI’s long-running staging in Las Vegas at the Las Vegas Convention Center, its west-coast venue beginning in 1998, continuing in 2001 and then recurring in even years 2004-2012.
The San Diego Convention Center size and scale, together with its proximity to extensive hotel facilities and transportation resources and services, is a defining factor in the LFI 2016 location decision. The Center is conveniently located within walking distance of more than 11,000 first-class hotel rooms and scenic San Diego Bay. San Diego International Airport’s advantageous location within three miles of the Center offers additional convenience with LED linear high bay light airlines serving 54 domestic and international destinations. With more than 500,000 square feet of exhibit hall space, the Center is well equipped to house LFI’s rapidly growing presentation of lighting, energy and design products, systems and technologies.

The electrical contractor for all light fittings
Brand experience company Innovision originally commissioned lighting designer Paul Cook and a handful of experts from the electrical, lighting and design industries to illuminate the six bridges that run either side of Hungerford Bridge.
London, Southwark, Millennium, Blackfriars and Waterloo Bridge, plus the Golden Jubilee footbridge, were all studied carefully before a tailor-made design was employed for each bridge.
Lighting solutions company Architainment supplied a range of Color Kinetic LEDs and provided technical support and wifi for all the bridges. The arches of Waterloo Bridge were illuminated by four ColorReach and two ColorBlast LED fittings on each of the four piers and the suspension wires and arms of the Golden Jubilee footbridges were fitted with Philips Color Kinetics ColorBurst fixtures. London Bridge was fitted with 36 Philips Color Kinetics ColorBlast 12 Powercore XRE fittings.
Pharos LPC lighting controllers were installed by Pharos technicians, while PRG supplied the rental equipment and customised some of the fixtures against weather damage. Proctor and Co Ltd were appointed by main contractor FM Conway as the electrical contractor for all light fittings, power and data cables.
