Entertainment applications will adopt the new LEDs

The number and breadth of applications that require amber LEDs is tremendous,” said Frank Harder, VP of Product Marketing at Philips Lumileds. “Markets including automotive, entertainment, roadway, signaling, and many others use amber LEDs. With better efficiency and more light output, LUXEON Rebel PC amber makes it that much easier to reduce energy consumption with an environmentally friendly product.lamps to LEDs because they didn’t produce enough light and couldn’t operate effectively at higher temperatures. With the advances provided by LUXEON Rebel PC Amber, yellow traffic signals will be converted, warning lights and beacons on vehicles and obstructions will switch and entertainment applications will adopt the new LEDs.

numbers of amber LEDs. With LUXEON Rebel PC Amber, manufacturers will be able to use fewer LEDs and lower other component costs because of the improved light output and particularly the stable color over temperature, something that has been problematic for many auto manufacturers. Philips Lumileds expects full automotive qualification later this year.Lumileds is the world's leading provider of power LEDs for illumination solutions. The company's leading light output, efficacy and thermal management are direct results of the ongoing commitment to advancing solid-state lighting technology and enabling lighting solutions that are more environmentally friendly, help reduce CO2 emissions and reduce the need for power plant expansion. Philips Lumileds' LUXEON LEDs are enabling new solutions for shop lighting, outdoor lighting, office and school lighting, and home lighting.

The HV9985 contains three peak current mode controllers that provide feedback to the IC and ensure higher efficiency and higher accuracy. Gate drivers within the chip are optimized for driving logic level FETs at 0.25A sourcing or 0.5A sinking. Each output current can be individually dimmed via linear or PWM dimming methods.The HV9985's closed loop system dynamically adjusts its output voltage for excellent line and load regulation of the LED current," states Ahmed Masood, Vice President of Marketing for Supertex. "Integrating three channels in a single package ensures better current matching between strings as well as reducing the total component count of the system.

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...
