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...

LED lighting to reduce both power consumption

The new product is designed for use in bus & taxi stops, benches and walkway coverings and other public spaces. It is set to sell from July 20, exclusive to the Japanese market, targeting municipalities and led linear high bay light private companies. And the two manufacturers also propose its use for a wide range of applications across Japan. Its key features including:Firstly the shelter's solar power generating system can supply electricity for surrounding electrical needs, such as lighting for advertising displays, with excess power being sold to the power utility companies, thus helping to meet expected power shortages in Japan during the summer. Secondly, LED lighting to reduce both power consumption and CO2 emissions at night. Moreover, the shelter can play as emergency power supplier in the event of a disaster, as it has an independent power outlet that could be used to charge mobile phones or other vital electronics. During the several years, LED lights have gradua...

although some of the monster screens had relatively narrow viewing angles

Spark new tunnel light series includes 50w, 75w, 100w, 125w, 150w, 175w, 200w, which could meet different project requirements. From the exhibition we know Spark new LED tunnel light will be more and more popular, and illluminate more and more tunnels all around the world. Consumer Reports didn't render a verdict after just a quick look, but noted that Sharp "has definitely taken the lead in larger TV screen sizes." It cited the 60-, 70- and 80-inch sets from the past, saying they had typically done well in TV ratings, although some of the monster screens had relatively narrow viewing angles. Consumer Reports pointed out a question that "not everyone has the room -- or room in the budget -- for a 90-inch set." So, when rolling out the world's biggest TV (in its class, anyway), why bother with subtlety and understatement, right?Sharp Electronics of America President John Herrington said it "offers size, picture quality and smart functionality unlike anyt...
