The addition of a new UV LED reactor will allow SemiLEDs to continue to build on the momentum of the rapidly growing UV LED market and confirms our position and commitment as a top supplier of led high bay light,” said Dr. Chuong Tran, SemiLEDs President and COO. “The addition of the new reactor will enable us to further improve the support and service we provide to a growing list of companies dedicated to the UV market through our broad portfolio of UV LEDs.
Lumileds said the new white paper goes beyond simple lumen maintenance data which describes how a single LED behaves and addresses the more common lighting system which uses multiple LEDs in a wide variety of use conditions.
An LED luminaire's usable life is determined by a manufacturer's determination of expected lumen maintenance and by the actual usable life of the many components included in the system. Each of the LED high bay lighting components must be analyzed independently in order to provide an accurate assessment.

the control and dimming of compact fluorescent lamps and LED lamps
Different moods, activities and times of the day require different light levels. Digitally controlled and infinitely variable digitally dimmable lights, for example at the workplace, not only save energy, but also ensure the right ambience at any given time. With Dulux Intelligent Dim Lamps by OSRAM, replacing conventional incandescent led high bay light with compact fluorescent lamps is simple and straightforward.
Working with dimmer manufacturers Insta, Berker, Gira and Jung, OSRAM is currently in the process of developing Leditron, the new industrial standard and the "future of dimming".The new Dulux Intelligent Dim Lamps with Leditron technology are the right choice forpremium applications such as hotels or restaurants, offices or in the home. In modern systems for the control and dimming of compact fluorescent lamps and LED lamps, they are immediately ready for use without addressing.
Even greater lighting comfort in combination with energy savings will be available in the very near future thanks to a new dimmer and control technology currently under joint development by OSRAM and dimmer manufacturers Berker, Gira, Jung and Insta. Under the motto "The future of dimming", the companies present the new Leditron standard at the Light + Building 2010 trade fair.
Up to now, only a few models of compact fluorescent lamps - or energy saving lamps – have been suitable for dimming. Occasional accompaniments such as flickering or uneven dimming will be made a thing of the past thanks to Leditron.
The basic principle of LED high bay lighting this new technology is to replace dimmers by control units and to send the control information via the mains to the lights connected to a particular circuit. In this way, not only the brightness of the lamps can be varied, but for suitable lights on LED basis, the idea is also to control the light colour simply and standard-compliant.

we can help them with customization of software locally
In addition to system performance, the quality of Labsphere’s sales support impressed the Institute. During system development, US staff flew to Shanghai to meet with the Institute face to face, along with Labsphere’s local sales and applications engineers. Now that the system is in place, Labsphere’s Shanghai-based team will be available on an ongoing basis for upgrades to meet evolving LED market needs.
“The Labsphere system is ideal as we will be able to upgrade it for certain applications. The system is also tailored specifically to new solid state lighting sources,” said Steven Li, the Institute’s General Evaluation Lab Manager.Per Roger Xiao, Asia Pacific Sales Director of Labsphere, a key reason the Institute selected Labsphere is, “Labsphere can commit to the customer that we can help them with customization of software locally; also both parties can cooperate on building a SSL test and measurement platform that complies with international industry trends.”
He is widely known for having developed the high-brightness blue LED based on GaN in 1993 while working for Nichia Corporation in Japan. In those days, developing a blue LED was considered impossible; only red and green LEDs had been available for the prior 20 years. Prof. Nakamura’s innovation allowed LED manufacturers to produce LEDs with three primary colors (red, green and blue) which could be mixed to express 16 million colors. Perhaps most importantly, the new technology was leveraged by the LED industry to begin commercial production of white LEDs, the semiconductor ecological light source.
