the functions necessary to implement a supercapacitor based LED flash driver solution

Increased resolution in camera phones and standalone digital cameras requires a high intensity LED flash current beyond the capabilities of standard lithium-ion batteries. The XRP6840 alleviates such peak current requirements by constantly sourcing a low controlled current from the system's battery to charge a supercapacitor which in turn provides the power for peak load functions. Charging and discharging parameters of the supercapacitor are completely managed by the XRP6840 and fully programmable via an industry standard I2C interface. The XRP6840 supports high peak current functions in battery operated portable systems while significantly increasing battery life.

The XRP6840 combines and manages in a single device all the functions necessary to implement a supercapacitor based LED flash driver solution. Supporting programmable current in torch and flash modes, the device comes in both two and three channel versions for increased design flexibility and supports up to 600mA of constant charging current. Built around tri-mode charge pump architecture and operating at 2.4MHz, the XRP6840 provides inrush current control and device protection circuitry while a standard I2C interface provides a seamless integration into any system.

In doing so, Rutronik extends its product range of visible and invisible LEDs. Brtled products combine first-class quality with an attractive price-performance ratio. The product range covers standard LEDs, high power LEDs and ultra high power LEDs as well as standard and customised led high bay light, optocouplers, photodiodes and phototransistors up to infrared transmitters, receivers and receiver modules. Together, Rutronik and Brtled focus in particular on white goods markets such as components and displays for cooker control units with a temperature performance of up to 125°C, general and interior lighting and the consumer, communications and computing industries.

The specialty crop industry plays an enormously important part in American agriculture

The USDA Specialty Crops Research Initiative Award will include $2.44 million from the USDA and an equal amount of in-kind contributions of equipment and services from industry partners. The project is titled "Developing LED Linear high bay light Technology and Practices for Sustainable Specialty-Crop Production." Merrigan pointed out that” The specialty crop industry plays an enormously important part in American agriculture and is valued at approximately $50 billion every year. These projects will be key to providing specialty crop producers with the information and tools they need to successfully grow, process, and market safe and high-quality products." In the process of the project, Mitchell will test led high bay light on high-wire tomatoes. He believes that using LED lights on the sides of plants will increase photosynthesis and flowering, improving yield. Roberto Lopez, an assistant professor of horticulture, will work with about 20 species of bedding pla...

We expect global sales to be about 60 percent of YAHAM going forward

Rice has served customers, built partnerships and done deals around the world for more than 20 years.He will be responsible for all non-U.S. markets with particular emphasis on high-growth markets such as China, India, the Middle East and Brazil where he will accelerate LED Linear high bay light efforts to meet customer needs with GE’s leading technology and services. In many of these markets, this includes GE’s “company to country” growth strategy in which GE works directly with governments to meet local needs. According to GE Chairman and CEO Jeff Immelt, “We expect global sales to be about 60 percent of GE going forward. Our global growth has expanded by about 15 percent a year for most of the past decade and we expect it to continue in the future,” Rice will oversee 12 integrated local organizations that will include business development, commercial teams, finance, led high bay light controllership and legal. This will include China, India, Southeast Asia, Latin/South America,...

automation solutions for the semiconductor industry

Taiwan semiconductor and panel equipment maker Gallant Precision Machining (GPM), reported November revenues of led high bay light , which was of NT$319 million in October. GPM's revenues for the first 11 months of 2010 increased 57.4% from a year earlier to total NT$2.96 billion. The company estimated its equipment for panels, solar energy products and semiconductor would account for 40%, 25% and 25%, respectively, of 2010 revenues. GPM mainly produced back-end automation solutions for the semiconductor industry, and supplied equipment for the FPD and LED industries . Also, the company made equipments for the production of solar cells. The company estimated the revenues would grow 20-30% in 2011, not include the revenues from the semiconductor business sales. At present, the company had transferred its semiconductor business to LED Linear high bay light , its wholly-owned subsidiary in China specializing in semiconductor manufacturing equipment.
