It happens nearly a quarter-billion times a day in the USA
They've soared in popularity, and now the U.S. government is having its say over the regulation of electronic cigarettes. The FDA is banning the sale of e-cigarettes to minors — but flavors such as chocolate or bubble gum, which public health officials say might attract children, are fine. The proposed rules won't ban advertising unless the products make health-related claims.
Nation's bridges are falling apart — and we're still driving on them
It happens nearly a quarter-billion times a day in the USA: A car drives across one of the nation's 63,000 structurally compromised bridges. That's from a new analysis by the industry group the American Road & Transportation Builders Association, which is warning that the situation might get worse. The report comes against the backdrop of growing cries of alarm that the federal Highway Trust Fund, normally used to pay for roads and transit projects, could be insolvent by the fall unless Congress acts.
the coverage of discount beneficiaries
Currently, there are about 20 products eligible to use the Lighting Facts label. And Radionic is the first to receive the label for under-cabinet LED lighting fixtures, the DOE has confirmed.Similar to the label one might find on the back of a food carton, Radionic will include a “Lighting Facts” label (see image) on its LED products so that consumers can more easily understand and compare solid-state lighting products.The lighting industry has yet to release an affordable, high quality under-cabinet led high bay light, said Radionic CEO Jeffrey Winton. The first Radionic products to undergo the independent lab tests required to receive the Lighting Facts label included its ZX Series in warm white. The ZX Series is engineered to emit comparable light to a typical fluorescent under-cabinet fixture, but will use approximately half the energy, according to the company.
The five measures include replacing Taiwan`s 260,000 incandescent traffic lights with LED lamps, further cutting electrical-bill discount rate and enlarging the coverage of discount beneficiaries, applying solar energy to public buildings, building a solar power plant, and assisting local governments set up LED-streetlight demonstration system.The government will appropriate NT$484 million (US$14.6 million) from its economic stimulus budget to finance installation of solar-energy equipment at selected public sites, according to Senior MOEA officials. And this measure is estimated to bring NT$1 billion (US$30.3 million) worth of business to the island’s solar-energy industry as well as sharpen its competitive edge.
Discount beneficiary coverage, according to the officials, will be expanded to include public facilities at residential communities, residential houses as well as junior and senior high schools already using the discount incentive. Maximum discount rate can reach 70%, and the new formula will come into effect on July 1.The measure will save estimated 3.8 billion megawatt/hour of electricity and over 3.29 million metric tons of carbon-dioxide emission in 2009.With testing and evaluation complete, Greenlight and Array have concluded a national and municipal/public works accounts sales agreement for Array's full line including PAR30, PAR16, MR16 and GU10-type LED replacement lamp products.

Can users continuously buy the same LEDs luminaires for a long period
LEDs for illumination seem to be rapidly growing in some developing countries, particularly in China for government backed national-wide street lighting projects. But traditional lighting giants still hesitate to jump into this huge market since some intrinsic issues exist in the LEDs industry for real illumination applications. The problems can be concluded “Does the useful life (L70) of high power LEDs lighting Luminaires can be really lasting for a long term (>50,000 hrs) as claimed? Do lighting companies can offer a sustainable LEDs Luminaire to fitting the applications from time to time?” Can users continuously buy the same LEDs luminaires for a long period?”
In NeoPac, we are completely solving the problem by offering NeoPac Universal Platform (NUP) and sustainable standard LEDs light sources to the industry. By adopting our fixed-maintained-lumen and form factor, 60,000 hrs useful life (L70) , system-in-package, point-like-source NeoPac Light Engines, the lighting brands will be able to make their own sustainable NUP-based luminaires easily to fit actual market needs” Jeffrey Chen said.
NeoPac Opto is going to launch its standard point-like-source NeoPac Light Engines at 500 lm, 700 lm, 1000 lm in White and 350 lm, 500 lm, 700 lm in Warm this year and adding 1400 lm in White and 1000 lm in Warm in 2010. Another 2000 lm in White and 1400 lm in Warm will be expected to launch in 2012. There will be totally 10 standard LEDs lamps with sustainable form factor (500 lm/700 lm/1000 lm/1400 lm/2000 lm in White and 350 lm/500 lm/700 lm/1000 lm/1400 lm in warm) for steadily offering to lighting industry in coming years.
If we can’t define the maintained lumen output and useful life (L70) of a lamp, we can’t call the lamp a real light bulb! This is really an intrinsic problem for current LEDs package and LEDs lighting technology platform. Even same LEDs package (lamp) adopted by different luminaire makers will result different lighting effects and different product useful life (L70). Since LEDs chips and phosphor are highly temperature-sensitive and high Tj will directly impact on optical and electrical performance of LEDs, as well as the overall quality and reliability of LEDs Luminaires. Different lighting fixture assembly process and different thermal management scheme result different LEDs junction temperature (Tj) and further result different overall lighting performance.

which implies a shift in focus from conventional vehicle lighting to technology
The LED manufacturers such as NICHIA, TOYODO GOSEI, CREE, GELCORE, LUMILEDS and OSRAM are also the main LED technology developers, while the other manufacturers from Taiwan and China like Everlight, Epistar and OPTO-TECH relies on their patents. And in China, the LED industry is mainly distributed in the regions of YRD, PRD and Jiangxi Province, Fujian Province, and Bohai Bay.According to people familiar with the acquisition plan, Epistar will first buy the 30% ownership in Huga held by Inventec Corp. Before this deal, Epistar has acquired four domestic peers including United Epitaxy Co., Ltd. and South Epitaxy Corp, and has become world`s biggest red LED chips supplier.
According to a Digital Light representative, the message behind the display is that with the advent of ultra-efficient LED products, consumers can now toss out their fluorescent bulbs — along with incandescents, which are already being phased out by federal legislation.
As Taiwan has been a major development and production base for aftermarket (AM) auto-lamp products and also a solid infrastructure and comprehensive supply chains in the electronics, opto-electrical machinery, light-emitting diode (LED), and semiconductor industries, private manufacturers and research organizations have been working to integrate related resources and further strengthen the auto-lamp industry by upgrading technical capability, product quality, and development and innovation ability.More and more international companies, said ARTC president Joe Huang, such as Philips of the Netherlands, Hella of Germany, and Koito of Japan, along with some universities in mainland China, Hong Kong, and elsewhere, have been setting up sophisticated R&D centers, which implies a shift in focus from conventional vehicle lighting to technology- and optical design-oriented vehicular systems.

the needs of a variety of markets ranging from consumer lifestyle products
A centre of excellence in conducting, promoting, and transferring technological innovations, NAMI is a Hong Kong R&D Centre with major funding support from the Innovation and Technology Commission of the Government of the Hong Kong Special Administrative Region and hosted by led high bay light. NAMI focuses on the development of nanotechnology and advanced materials to serve the needs of a variety of markets ranging from consumer lifestyle products, enhanced properties for building materials to environmental technology for lighting, waste treatment and renewable energy.
Co-organized with Hong Kong Trade Development Council, the forum had invited distinguished speakers from universities and the LED industry to share their views of the latest solid state lighting development, its feasibility in general lighting applications, potentials, and challenges. It also provided a unique platform where academics, business professionals, government officials, and end users from lighting, building and services industry to exchange their ideas and experience on the use of LED and OLED.
The 20,000 hour plus lifetime of the LED significantly reduces the maintenance costs of the LC-L2, and there is no need for optical alignment either. Much smaller required volume is also achieved comparing with its LC-L1 predecessor via the modular design of LC-L2 that incorporates all necessary drive circuits and makes the new device more cost-effective. The high-power LEDs are capable of a UV irradiation intensity of led high bay light at a peak wavelength of 365nm, which is considerably higher than the intensity from the LC-L1 and conventional mercury-xenon lamp curing systems, such as the Hamamatsu LC8 series, which creates a wider range of curing possibilities.

it won't reach the necessary economies of scale
In addition, the report notes that LED industry faces several challenges. Vendors must work with legislators and industry groups to foster a smooth, orderly transition from incandescent bulbs to the more efficient LEDs.LEDs consume less power than the current mainstream fluorescent lamps, or CCFLs, used in flat-panels. LEDs take up less space and are more environmentally friendly with no mercury content but their weak point are their high prices. The expert says with Samsung's investment size, it won't reach the necessary economies of scale.According to a recent report, the sales of led high bay light are about to boom as they improve in quality, and LED product sales will reach $22 billion in 2009 and $33 billion by 2013. The U.S. Department of Energy predicts that LEDs will be 70% of the lighting market in 20 years.The Dubai Mall is the world’s largest shopping centre sprawling over 12 million square feet with an internal floor area of 5.9 million square feet. Housing more than 1,200 stores and a host of world class attractions -- including an Aquarium and underwater zoo, Ice Rink, Cineplex and a spectacular water feature that runs the entire height of the Mall traversing all four levels -- the Dubai Mall is revolutionizing the modern shopping experience.
The fashion area, a dedicated haute couture precinct with 70 signature shops, has the fashion catwalk at its heart. Advanced LEDs has created a stunning focal fixture above the catwalk, by lighting the huge sails with 6.5 kW LED lighting from 76 specially-designed RGBW fittings. Each fitting is individually controlled through wireless DMX. The sails (colored green, red or blue in the three photos) are lit with perfect uniformity as their colors change dramatically up and down through the encircling LED screen rings. The sails have also been designed for image projection.

The exhibited items are LED light
Lighting Fair 2009 hold a seminar titled "LED and organic EL pave the road to the future of illumination". The panel discussion was participated by Shuji Nakamura, a professor of the University of California at Santa Barbara, a developer of blue LED and a leader in the research of GaN-based light-emitting element and Junji Kido, who leads the research of the led high bay light as a professor of Yamagata University Graduate School of Science and Engineering.The international conference hall at Tokyo Big Site was crowded with listeners. The panelists discussed possibilities as well as barriers that interfere with the promotion of LED lights and organic EL lights. The panel discussion was coordinated by lighting designer Tsutomu Ochiai, head of M&O Design Office.
The Lighting Fair is held every two years, but this year's fair is different from previous ones in that the site is full of LED lights. The discussion was started with comments on the exhibition site by Nakamura and Kido. Nakamura said he was surprised because this exhibition is quite different from the previous ones, more than 90% of the exhibited items are LED lights. He also said that 20 - 30% of the exhibits were LED lights and existing light sources including fluorescent lights were the main exhibits at an exhibition of lighting devices he visited two or three years ago in the US.Nakamura expects that luminance efficiency of white LEDs will be enhanced by at least 50% in two to three years, judging from the progress in the research and development of white LEDs. In a speech delivered prior to the panel discussion, he said it is possible that the luminance efficiency will reach 200 to 250lm/W in two to three years.
Kido said fluorescent lights were the main players at the exhibition four years ago, but with the number of LED lights increased, this year's show can be called an LED Fair. He also pointed out the rapid progress in the development of LED light technologies. In his speech delivered prior to the panel discussion, Kido said that organic EL lights have been steadily evolving in terms of luminance efficiency and lifetime and that the research and development of them are two to three years behind those of white led high bay light.while talking about the rapid evolution of LED lights, he expressed concern in respect to business model. He is worried that the Japanese LED light market might become like the Galapagos Islands, where species evolved differently.

LED Streetlight reduces drastically light pollution
Neo-Neon LED Streetlights place light directionally, onto the ground where it is needed, without the estimated 30% of outdoor light pollution from other forms of lighting. A Neo-Neon LED Streetlight reduces drastically light pollution and aids the global Dark Skies Initiative. The energy efficiency led high bay light stems from the technological advancements in White LED Production process, the custom designed optics such as led high bay light technology, and other green processes to create the most economical product possible.
The greatest advantage of the LED Streetlight by Neo-Neon is energy saving. Neo-Neon’s LED streetlights can reduce energy usage by at least 50% compared to high pressure sodium. Another important benefit of LED streetlights by Neo-Neon is the reduction of maintenance over time and it is possible to save up to 75% of the total service costs that exist with traditional streetlight fixtures.As with all newer technologies the initial investment is slightly higher than installing existing lamp based fixtures but coupled with the compounded energy savings, greatly reduced maintenance costs, extended lifetime of LED vs. lamps, dramatic reduction of light pollution and enhanced colour rendering of LED Lighting the additional costs are recovered many times over in life of the lamp with high environmental benefits.
Neo-Neon is aware of the toxins such as Mercury that are involved in the construction of traditional lamps. Not only should they as a people be focusing on energy savings, they should also be focusing on true “green” technologies. Neo-Neon LED Streetlights contain no mercury and are completely recyclable. The company says its led high bay light assuredly will have a place in that solution to the global economic crisis.The housing for Sierra 6500 column is extruded aluminum. Overall height is twenty-one feet with a diameter of ten inches. A flush hand-hole cover has tamper-resistant locking device. Lens is impact-resistant matte acrylic. Mounting options include internal flange with anchor bolts or external flange with anchor bolts and base cover.

achievement in setting efficiency records for white LED lighting
A team of three electrical and electronic engineers, led by Kubik's Mike Hudson, spent eight weeks on research and development and built the modules for the floor in less than four weeks. Besides the aesthetical, illumination and market-related brief, the development team was asked to create a product with a minimum ten-year lifespan as well as to create an energy-saving, recyclable, ‘green' product.Kubik says that the high-quality electronic components and the LEDs, which are mounted on a heat sink aluminium frame, the right selection of cables and the thermostat-controlled power consoles, guarantee a power consumption of only 35 Wm2, which is equal to a small light bulb or night-table lamp.
Hudson says that all the materials were chosen with recyclability in mind. He notes that glass is 100% recyclable, as are the aluminium frames and, thanks to the intelligent design and the use of low voltage, they can reduce the amount of electrical cables and components to an absolute minimum.LED technology, announced that the company's research advances in white LED lighting performance was honored by the U.S. Department of Energy (DOE) during the DOE's Annual Solid-State Lighting Workshop. With the support of the DOE, Universal Display has been working on developing highly-efficient white LEDs for use in myriad lighting applications.
Dr. James Brodrick, DOE Lighting Program Manager, recognized Universal Display's achievement in setting efficiency records for white LED lighting. Dr. Michael Hack of Universal Display also spoke about recent advances and Universal Display's development of white LED lighting in a presentation titled "Pushing the Envelope for White LED efficiencies. In particular, Dr. Hack highlighted Universal Display's 2008 demonstration of a white LED light source with record luminous efficiency of 102 lm/W, a significant leap forward in LED efficiency. That milestone placed LED development well on the way to achieving the DOE's target of a 150 lm/W LED lighting device by 2015.

which can result in inaccurate current readings
The yaham offers superior temperature control through its proprietary LED-Sense Temperature Compensation engine. Existing solutions either place a sensor in the proximity of the LEDs, which increases cost and reduces the available footprint of the phone, or rely on measuring temperature only inside the LED driver chip, which can result in inaccurate current readings. The led high bay light, however, measures the temperature of each LED at the diode itself. This in-situ measurement doubles the accuracy and does not require extra sensor components on the board. Every few seconds, the measured temperature is fed into Leadis' proprietary compensation engine that adjusts the current on each LED channel in order to optimize luminosity, color saturation and to prevent system overheating. Sixteen I2C-programmable registers for each of 3 channel banks let users define the compensation curve as a function of the specific LED Diode used in the design.
Major bulb manufacturers and retailers are meeting in Dallas this week to find ways to incorporate LEDs into more products, but have been in transition mode for years. General Electric has closed lighting plants in Brazil, Mexico, and the United States, and Osram Sylvania is modifying existing plants. The European Union will start phasing out incandescent bulbs this September.The incandescent bulb is about to become obsolete is lost on the vast majority of the public. The phase-out begins in three years as part of the energy bill signed in 2007. They will be edged out by LEDs. So light bulb makers have to revamp some plants, shutter others, and invest enormous sums of money in preparation for a technological shift.
Incandescent bulbs, invented by Thomas Edison more than 120 years ago, brighten a room by heating a metal filament in a vacuum, but waste large amounts of heat. Compact fluorescent bulbs contain a gas that reacts with electricity to create invisible ultraviolet light. When that light hits material inside the bulb, it is converted into ordinary led high bay light. LEDs emit very little heat, are about 40 percent more efficient, and can last for more than 50,000 hours. For instance, a typical 100-watt bulb be replaced by one that provides the same amount of light with 72 watts.Prices will come down as technology improves, said Charlie Jerabek, president and chief executive of Osram Sylvania. And the new bulbs do eventually pay off, economically and in efficiency.

the participants are taught methods for measuring
Rensselaer Polytechnic Institute’s Lighting Research Center (LRC) has enhanced its outreach education by taking the LED Lighting Institute “on the road.” In addition to the traditional three-day seminar held each spring and fall at the LRC, a two-day LED Lighting Institute program option has been added, which will be hosted at a program sponsor site each year.The first two-day, on-the-road LED Lighting Institute will be held led high bay light, at Cree Corporate Headquarters in Durham, North Carolina. It will provide detailed instruction for lighting fixture designers and manufacturers, lighting specifiers, and other professionals interested in learning more about this quickly evolving lighting technology.
Through hands-on workshops and classroom sessions, participants learn the basics of LED technology while building an understanding of LED system integration issues involving the electrical, optical, and thermal characteristics of LEDs. Participants also learn how to measure and evaluate LEDs and LED systems, and have the opportunity to compare LED technologies from a variety of manufacturers. The program culminates with the participants designing, building, and evaluating their own LED fixtures.
According to Dan Frering, LRC manager of education, the program is designed to have participants choose and evaluate all necessary LED system components including heat sinks, LEDs, and drivers from a variety of manufacturers. Then participants will have the opportunity to compare the systems side-by-side, examining the thermal, photometric, and color properties for each system.Director of research and head of the Solid-State Lighting Program at the LRC, noted that the workshop offers objective information on current led high bay light technology so participants walk away with realistic expectations for using LEDs in place of traditional light sources. In addition, the participants are taught methods for measuring and quantifying LED performance.

while LED panels only need to be turned on occasionally
Since the hazard levels in the standard are specific to the operating conditions of radiating products, it is impossible for LED component manufacturers to provide conclusive eye safety information specific to the end product implementation of their parts. For this and other reasons, it is critical that product manufacturers incorporating LEDs properly test and label their products for their intended system application.Orb Optronix offers product evaluation to the ANSI/IESNA RP-27 Recommended Practice for Photobiological Safety for Lamps and Lamp Systems, and led high bay light as a service to the LED and Solid State Lighting communities.In addition to its measurement services related to current standards, Orb Optronix works closely with medical physicist David Sliney, Ph.D., an expert in photo-biological safety, to provide additional in-depth analyses.
Until recently, there was confusion among manufacturers about the use of proper classification standards in differing markets. For instance, in some countries, products containing LEDs required a classification under a product standard intended for lasers, not LEDs. Fortunately, the recently published second edition of this laser product standard, which was sometimes difficult to apply to LEDs, no longer includes LEDs in its scope. IEC 62471 replaces IEC 60825-1 internationally for LEDs and provides methods to assess the risk of LEDs by classifying their risk group.In LED traffic sign applications, the dark pixels will still consume a lot of power over long periods of time. To solve this problem, the MBI5037 provides two power-saving modes: sleep mode and 0-Power mode. Both modes feature only 100uA power consumption and reach new stage of smart power-saving in LED traffic sign applications.
The MBI5037 can enter in sleep mode and wake up compulsorily by command. It is suitable for LED traffic sign applications while LED panels only need to be turned on occasionally. In the 0-Power mode, the led high bay light can save power automatically when all the output data are 0. It is suitable for LED traffic message sign, which partial of the LEDs are always turned-off. With MBI5037, users can easily design in their LED traffic sign applications with high efficiency, reliability and low cost.
