Toshiba America Electronic Components, Inc. announced its model TLWK1100B compact high-efficiency white LED. This LED offers luminous intensity levels of 1,500 mcd from a drive current of 20 mA (typical value). The robust design makes it suitable for automotive lighting designs, LCD backlighting, panel indicators and the replacement of incandescent bulbs in certain lighting applications.
LEDtronics announced its PAR20 LED short-neck light bulbs that are direct incandescent replacement bulbs which combine advanced LED technologies, standard 25 mm Edison screw bases and light-optimizing designs to produce vivid light. These bulbs are available in three light emitting angles (15°, 20° and 22°) and in 120V AC with other voltages available. The bulbs measure 3.50¨ long and 2.53¨ diameter, making them suitable for small spotlighting tasks
Global Lighting Technologies (GLT) introduced its MicroLens edge-lighting modules that provide white LED backlighting for LCDs in a multitude of functions for a variety of display applications. In addition to bright, clean, uniform white LED backlighting from an ultra-thin, low-power package, these light guides can provide discrete area backlighting for different parts of the display
Supertex introduced its HV9980 three channel, high voltage, LED driver IC that is well suited for LCD and DLP television applications. It features three channels of peak current mode control that include a switch for regulating the LED current, enabling 95 percent efficiency in DLP television applications. Each channel features an integrated, 160V, 25? MOSFET, individual PWM and linear dimming inputs.
American Bright Optoelectronics announced the BL-Hxxx7A-TRB series of small, low current surface mount LED in 0402 (1.0 mm × 0.5 mm × 0.4 mm) package size. The LED is compatible with infrared and vapor phase reflow solder processes and provides compatibility with industry standard automatic placement equipment. The series is RoHS compliant and compatible with industry accepted lead free processes.
Energy News: CNN posted a very solid overview story about the state of solar power. The technology, if we lived in a proverbial vacuum, can already provide all the world's energy needs by installing panels in a small corner of the Sahara. But in the real world, cost and security are
Thermocouples provide the key components of thermoelectric cooling modules. A thermocouple comprises a p-type and an n-type semiconductor element connected by a metal plate. Electrical connections at each end of the p- and n-type material complete an electric circuit. When a source supplies a current, thermoelectric cooling occurs. The thermocouple then "pumps" heat by cooling one side and heating the other by what is known as the Peltier effect.
National Semiconductor Corporation announced the addition of two new, high-efficiency Simple Switcher synchronous buck regulators to its PowerWise energy-efficient product family. The highly integrated LM3102 and LM3103 are said to be the industry’s first synchronous buck regulators to feature an input voltage range up to 42V. The ICs are optimized for powering digital integrated circuits (ICs) in industrial and telecommunication applications. Integration of MOSFET switches and the use of small inductors enables a reduced system component count and very small solution size
Energy News: More than a third of enterprise CIOs don't monitor their corporate energy use, according to an Economist Intelligence Unit report, commissioned by IBM. "Although concerns about energy efficiency and global warming are now high on the political agenda, the spotlight
Supertex introduced the HV9982 three channel LED driver IC designed to provide high LED current accuracy through closed-loop control of the output currents. It is designed for applications using RGB LED backlighting or multiple strings of white LEDs. The device employs a fixed frequency, closed-loop, current mode control architecture that ensures stable operation over a wide range of input and output voltages.
