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.

while all of hit new record quarterly highs

As a result, to increase greenhouse yields and decrease producers' energy costs, they will team up with Rutgers University, the University of Arizona, Michigan State University, and Orbital Technologies Corp. on the four-year project to improve and evaluate LED lighting for greenhouse use, according to Cary Mitchell, a professor of horticulture and project director for the grant. Total sales from January through September of 2010 hit NT$92.88 billion, up 35% YoY. Meanwhile, operating profit and net profit reached NT$5.67 billion and NT$6.8 billion respectively, with accumulated EPS of NT$3.05 increasing a remarkable 50% YoY. In 3Q10, The Company’s gross margin and operating margin reached 13.9% and 6.7%, up 0.9% and 0.4% QoQ, respectively. Lite-On’s net cash position held steady at NT$11.9 billion, after its recent cash dividend distribution of NT$5 billion. Non-operating items posted a net income of NT$508 million in3Q, with Perlos’ Q3 sales reaching €138 million, up 12% YoY. Perl...

It is extremely rare for the government to ask retailers

Stephan Wittekind, Business Development Director at Traxon, said, “The highlight of this concept is that the fixtures are completely integrated into the semi-transparent structure. Therefore, they are not visible during the day, and the appearance of the stadium is completely different by night.” According to The Yomiuri Shimbun, Japanese government has encouraged major electronics retailers and home appliance makers to voluntarily halt production and sales of incandescent bulbs to save Led linear high bay light power this summer. The government plans to submit a written request under the names of Economy, Trade and Industry Minister Yukio Edano and Environment Minister Goshi Hosono to an industry group, probably sometime this week. The industry side has indicated it will oblige. It is extremely rare for the government to ask retailers and manufacturers to refrain voluntarily from selling and producing specific products.The two ministers plan to send their request to Sho-ene Akar...

Universal Display will develop new technologies and processes for OLED manufacturing

In addition to the patent sale, the 2 companies are engaged in “a strategic relationship,” with strengthened and enhanced alliances between the companies. Fujifilm will expand its business for the supply of Fujifilm's highly functional materials, such as barrier films, conductive films and flexible substrates, to OLED manufacturers globally, including Universal Display's worldwide customer base. Universal Display will develop new technologies and processes for OLED manufacturing. John R. Peeler, Veeco’s Chairman and Chief Executive Officer, commented, “Veeco continues to deliver solid results in a soft market. Second quarter revenue was $137 million, and adjusted EBITA and non-GAAP earnings per share were $20 million and $0.37, respectively, with gross margins of 45%. Veeco generated about $19 million in cash flow from operations, ending the quarter with $540 million in cash and short term investments.” Second quarter LED & Solar revenues were $87 million, including $75 mil...
