the chip with high efficiency resulting in high luminous intensity

The three independently controllable LED chips in blue, red and green in the MultiLED are available in different brightness groups thanks to finely defined grouping (known as binning). They can be individually combined to produce a large color spectrum. All three chip colors are the product led high bay of state-of-the-art technology: Blue and green in UX:3 technology, red in the latest thin-film technology. The light is therefore extracted from the chip with high efficiency resulting in high luminous intensity. In the upper blue wavelength range, for example, a figure of up to 560 millicandelas is achieved at an operating current of 20 mA. Luminous intensity in candela (cd) corresponds to luminous flux in lumen (lm) emitted by a light source in a particular solid angle. The typical thermal resistance between the chip and the solder point is 127 K/W for blue and green, and 96 K/W for red.

Osram Opto Semiconductors launches the Duris S 8, a new, multi-chip, high-power member of the Duris “S” LED series. The close grouping of the LED permits very good color consistency in combination with a high luminous flux. The new Duris S is primarily used in directional and omnidirectional retrofits, as well as in LED spots in indoor lighting. It is particularly suitable for directional lighting in office and business premises, as well as in the home.

The very good color consistency (color binning) in the directional retrofits is achieved through the close grouping of the led high bay light, which corresponds to the coverage of a 5-step MacAdam ellipse. 3-step MacAdam grouping is additionally available for applications requiring very good color homogeneity. The Duris S 8 is grouped by color coordinates at the junction temperature of 100 °C instead of at room temperature, as is customary. “In terms of color rendering, the Duris S 8 has a CRI of more than 80. An even higher CRI will be the next step,” says Janick Ihringer, the responsible Product Manager SSL at Osram Opto Semiconductors.

Only imaginations brought the ceremony

In 1923, families gathered around the radio to listen as President Calvin Coolidge lit the first National Christmas Tree. Only imaginations brought the ceremony, and the tree located in what is now President’s led linear high bay light , to life. Eighty-nine years later, families are still gathering to witness the lighting of the National Christmas Tree, but 21st century technology is giving them a front-row seat. At 4:30 p.m. ET on Dec. 1, GE Lighting, in conjunction with the National Park Foundation, an official charitable partner of America’s national parks and the National Park Service, invites families to gather around the laptop to watch as the National Christmas Tree come to life. GE Lighting has been designing the National Christmas Tree, and contributing its lighting and decorations for 49 years.  The design process usually begins only a few months after the previous year’s lighting on the National Christmas Tree is shut off, often starting in March or earlier.

In order to take maximum advantage of opportunities

Recently, China government promoted LED solid state lighting and listed Beijing as a level-one city for demonstration. Meanwhile, BOE's 8G plant scheduled to start mass production in 2011, LED backlight unit (BLU) demand from BOE was expected to surge. Additionally, Everlight was listed as one of BOE's backlighting suppliers. In order to take maximum advantage of opportunities, Everlight decided to set up a production plant in Beijing. Market sources noted, Currently all LED Linear high bay light notebook products were LED backlit. BOE's overall LED demand from its 5G and 6G plants was expected to exceed one billion chips in 2011, and to over seven billion chips when BOE's advanced production lines came online in the future. If BOE's 8G line fully adopted LED backlighting, BOE would need the support of about 20 LED production lines, or five billion LED chips per year, and generate CNY10 billion (US$1.5 billion) worth of industry value. The vertically-integrate...

winners will be recognized with personalized plaques acknowledging their lighting design achievements

The Award for Environmental Design gives special recognition to projects that minimize the use of energy, maximize the use of daylighting, control light pollution, and ensure system durability and maintainability. All qualifying entrants will be invited to an awards ceremony, which will take place Monday, April 22, 2013, in Philadelphia, Pennsylvania, USA, on the evening prior to the opening of LightFair International, the world’s largest annual architectural and commercial lighting trade show and conference. At that time, all winners will be recognized with personalized plaques acknowledging their lighting design achievements. The identity of the 2012 GE Edison Award Winner will remain confidential until announced at the awards ceremony. The winner will receive a personalized Steuben crystal trophy and continued publicity throughout the following year. A distinctive plaque also will be presented to the owner of the winning installation. The products manufactured in the plant is expect...
