who is also heading its LED Technologies business unit

After questions about achieving competitive brightness and efficiency levels have been answered by various GaN-on-Si contenders, the yield question has remained open. The large mismatch of crystal lattice structure and thermal expansion coefficient cause highly bowed led high bay light after and during growth. This in turn has a very big negative impact on uniformity levels for wavelength, forward voltage and output power. The company uses its proprietary and patented strain-engineering and growth technologies to overcome these obstacles.
Azzurro’s latest results from production and development clearly prove that in addition to the cost advantages from lower cost substrates and by using standard silicon fabs for LED chip processing GaNon-Si LED wafers with the right strain-engineering technology can also help reduce binning dramatically.Alexander Loesing, who is also heading its LED Technologies business unit, commented on the results: “We are very proud of our team’s record 1.0 nm achievement.
Open Technology’s LiGO control system will provide the exact light levels required across the station, matching lighting use to train timetable, passenger presence, daylight levels and other varying uses. The system is able to ensure maximum savings throughout the year as well as reduce light pollution in the surrounding area.
For the first time, Clapham Junction station will automatically be able to dim the lights down to a minimum value when the station is not in operation or switch the lights off when the station is completely closed. On average, this would amount to savings of 35% of usual lighting use.Delivery of a safe environment is of paramount importance in the transport sector. Our LiGO system gives the confidence that appropriate light levels are maintained at all times, whilst ensuring that they are no higher than necessary. We are able to achieve maximum savings for the operators, alongside comfort and safety for staff and passengers” explained Open Technology Managing Director Chris Bedford.

Clapham Junction will be the latest in a series of projects that has seen Network Rail and South West Trains work in partnership with Open Technology to introduce intelligent lighting controls. Following an initial installation at Woking Station in 2010,led flood light has now been introduced at 25 stations and train maintenance depots across the Wessex Route.Installing lighting control is one part of the South West Trains, Network Rail Alliance’s climate change and energy reduction strategy that is estimated to achieve total annual savings of 7–12 million pounds and a payback period of approximately six years.

The standard can only be achieved through the use of improved LED chips

Trade barriers and technological barriers have brought new market changes recently, and affected China’s LED export companies. These have had two major effects, the first being increased export risks. As the bar for technological standards gradually rises, so has the report rate for Chinese exports, and significant increases in export risks.led flood light, for instance has reported of the 54 Chinese lighting products exported to China, 19 were LED lights, accounting for 35.18%, with a YOY increase of 23.61%.

The second effect has been increased costs for companies. Taking the new EU LED lighting product regulation as an example, starting from the second phase of the new regulation after Sept. 1, 2014, only LED lamps with high energy efficiency will be able to enter the EU market. As a result, manufactured LED products or OEM products must purchase and use better power management chips. The standard can only be achieved through the use of improved LED chips.


LED companies in the Asia market should improve the establishment of core technologies, study related export market laws, legal regulations, standards, and prepare in advance measures to cope with technology and trade issues. At the same time, the companies should also establish test laboratories approved by foreign countries to lower its testing fees and production costs.led high bay light companies should also consider developing LED “blue ocean markets,” such as Latin America, Africa, Middle East, Southeast Asia and other emerging markets.

a wider gamut of colors to deliver a new visual experience in image technology

Quantum Materials Corp. announced it has shipped Tetrapod Quantum Dots in sample quantities to a diversified leading Asian-based electronics manufacturer. Quantum Materials recently developed tetrapod quantum dots to meet the client's performance specifications.

Tetrapod Quantum Dots are an advanced nanoscale material that improves the performance and energy efficiency of led high bay light very high-resolution computer, TV and smartphone displays. Quantum Materials' patent-pending continuous-flow technology produces uniform, narrow bandwidth tetrapod quantum dots with bright emission, less aggregation, purer colors (including high-luminous red) and precise color rendition.

Manufacturers are seeking to "print" tetrapod quantum dots onto backplane films in liquid crystal displays (LCD) for brighter images, larger screens and a wider gamut of colors to deliver a new visual experience in image technology. Thinner, lighter, brighter and less expensive QD-LED displays, including portable and flexible devices, will offer almost infinite contrast levels, deep black levels and high light output with no motion blur or field-of-view issues.

"Tetrapod Quantum Dots ultimately allow for lower display manufacturing costs due to their superior luminescence and much lower incidence of aggregation,” said Stephen Squires, Quantum Materials Corp's Founder and CEO. “Far fewer quantum dots are required to achieve the same level of performance.The Future of Displays". The article details led flood light ability to reduce the cost of quantum dot creation while ensuring uniformity in quantities sufficient to meet high volume display-manufacturing needs.

Nichia has held a press conference in Taiwan to explain a patent dispute

Since 2002, Nichia has been involved in more than 50 global patent lawsuits, including against TG, Cree, Rohm and Osram, said Akutagawa. In most cases, the lawsuits ended respectably, in which both sides reached a settlement and exchanged patent rights. However, in Nichia’s case against LED high bay lighting, the Taiwanese manufacturer spread biased information over the past year, resulting in the Japanese manufacturer's skepticism of Everlight’s trustworthiness and patent development. Akutagawa frankly remarked there were no signs of conciliating with Everlight yet.

According to data from Nichia, there are currently eight patent lawsuits between the two companies. Out of these, Nichia accused Everlight over patent infringements in six cases, while the remaining two were filed by Everlight against Nichia.In the patent infringement case filed jointly by Everlight and U.S. fiber optic manufacturer Emcore against Nichia’s on April 9, 2012, the patent used by Everlight belonged to Emcore, according to Akutagawa.


This is the second time that Nichia has held a press conference in Taiwan to explain a patent dispute.Nichia’s attitude has become more hawkish compared to its last press conference back in June 2012 to explain Japan’s Patent Office’s ruling that invalidated the company's blue LED patents. Akutagawa pointed out, the main reason of organizing another press conference, was impact from information released by Everlight over the past year has mislead clients to believing the company patents were worthless. Nichia announced it will launch a full scale war against Everlight products that have infringed patent rights.

detail the effects of light on the biological clock

The all-glass pod is a prototype for the Photon Project that will collect invaluable data and insights on the links between light, and health and wellbeing over a planned four-year period. The Photon Project is a scientific study initiated by glass engineering company led flood light, and Oxford University, to explore in detail the effects of light on the biological clock – which in turn affects the health, wellbeing, mood and behavior of each of us.

The stunning glass pod installation showcased at London Design Festival invites the public to experience ‘life under glass’ and take part in a series of simulations that measure levels of alertness or relaxation in different light settings – illustrating the future research plans. Within the Photon Pod, visitors can also interact with Philips Hue providing a personal light experience. Tuneable white light from Hue can be controlled via a simple app to instantly match the mood and moment, and through pre-settings light can be set to help concentrate, relax or energize. The Photon Project and its founders at Cantifix share the belief that the results of the research can potentially contribute to improving the lives of millions, through new standards and light-related solutions for all sorts of buildings.


Sean Carney, YAHAM Chief Design Officer, will attend the Photon Project’s symposium at the London Design Festival and speak about the future possibilities of light. Sean comments: “With led high bay light, we are only beginning to understand the endless creative possibilities digital lighting will bring. As we acquire new insight into the physiological and psychological effects of light, programmable digital light sources such as Hue will allow us to apply light in ever more meaningful ways. Whether supporting our bodies’ own natural balance by simulating daylight or achieving something much deeper, promoting feelings of wellness.”

the company look into developing an interactive light product for children with disabilities

Philips has partnered up with Perkins Products, a provider of education, services and products to the blind, deafblind, and those with disabilities to develop Light Aide, a new LED device designed as a teaching tool for children with low vision or other disabilities. Arrays of multi-colored led flood light in Light Aide can be programmed and manipulated in various ways to help children get ready to learn reading, math and critical interactive skills. The product will be demonstrated at the Perkins Products booth during the Abilities Expo Boston, September 20-22 at the Boston Convention & Exhibition Center at booths 640 and 636.

Both Perkins and Philips have histories of innovation and collaboration, and this latest partnership was sparked by Philips employee Catherine Rose. Rose was working for Philips Healthcare when she noticed that the type of LED lighting used in the Philips Color Kinetics showroom could capture the attention of her seven-year-old daughter Alexis, who is deafblind. Realizing that the interactive displays of colored light could be a powerful learning tool, Rose suggested that the company look into developing an interactive light product for children with disabilities.


With support from Philips’ Lighting and Healthcare groups, Rose moved forward with a project that brought together Philips Color Kinetics engineers and staffers from Perkins Products. Educators and therapists at Perkins School for the Blind conducted tests and advised the designers. That interaction evolved into an increasingly sophisticated series of prototypes, incorporating feedback from teachers and students. Starting from a 7x7 prototype grid of 49 LED points of light, the final version of Light Aide with led high bay light in a 14x16 grid features an oversized switch button manageable for little hands with limited motor skills. A control panel on the side allows teachers to choose from a variety of educational activities.

LED Array delivers an impressive amount of light from a very small source

A breakthrough technology that doubles the system intensity of spot lights compared to previous arrays. The new HD class of CXA Arrays provide unrivaled lumen density, enabling major reduction in system cost and power consumption. The first HD Array, the CXA1520 LED, enables lighting manufacturers to create a new generation of products that delivers the same intensity and light quality as 39W ceramic metal halide (CMH) at up to 50 percent lower power.

“The new CXA1520 LED Array delivers an impressive amount of light from a very small source. I have not seen another integrated array that can match this level of lumen density,” said Mark Groenke, VP of engineering at ConTech Lighting. “The CXA1520 LED Array enables ConTech Lighting’s newest LED fixtures to exceed the efficiency and life of our ceramic metal halide fixture offerings while maintaining intensity and color quality.”
