Philips has announced a new addition to its Fortimo LED family - the Fortimo LED High Brightness Module (HBM). Fortimo LED HBM is an easy to design-in, compact, high lumen LED module for white light applications.

On Aug. 31, 2011, Nichia Corporation has filed a patent infringement lawsuit in Tokyo District Court to enjoin Chip One Stop, Inc. from infringing Nichia's patent (No. 4530094, or patent No. 094) with regard to white LED products (product number: GT 3528 series) manufactured by EVERLIGHT ELECTRONICS Co., Ltd.

Lumex announces the global expansion of the QuasarBrite™ UV family of LED technologies to include three new standard wavelengths and also announces the availability of custom UV LED arrays. QuasarBrite UV LEDs provide up to 10 times longer lifespan, up to 50% cost savings , up to 70% energy consumption savings, and superior light performance compared to alternative technologies.

LED lamps have a significantly higher reliability than incandescent bulbs. The potential savings in warranty repair when using LEDs instead of incandescent bulbs is highly attractive for automotive signal lamps—especially center high mount stop lamps (CHMSLs) and rear combination lamps.

This circuit is designed to replace a dual-filament incandescent bulb in a combined brake/tail light for automotive use. When power is applied to the 'Tail' input the current in the LED is regulated to 300mA. When power is applied to the 'Brake' input or both inputs simultaneously, the current in the LED increases to 900mA. The 'Brake' and 'Tail' input voltage can vary between 8V and 40V This makes the circuit suitable for standard passenger cars...

The Edison Opto has expanded its EdiPower®II product line to further increase choices for high voltage LEDs. The new EdiPower II-HV series delivers 710 to 1,300 operational lumens, two color temperatures including warm white and cool white are available, each with two different operating powers— 6-9W and 10-13W.

An expanded line of diffuser lens options for the Lithonia Lighting TLED luminaire enhances, once again, the Acuity Brands portfolio of indoor ambient LED lighting. The TLED luminaire – a high-quality, general-purpose troffer with flexible diffuser options – maximizes energy savings with the use of advanced LED lighting technology, full-range dimming, and flexible diffuser lens options. It’s part of Lithonia Lighting’s versatile recessed ...

With two new models in the 5.7 inch (14,4 cm) and 8.4 inch (21 cm) categories, Sharp continues to enhance its portfolio of backlit LED industrial displays. The target applications of the new industrial TFT LCDs are mainly testing and measuring instruments, portable medical monitoring devices and building automation systems.

austriamicrosystems has announced the AS1130, the most advanced and smallest dotmatrix LED driver (channels vs. PCB space) available. The AS1130 drives 132 LEDs but requires only 5 mm² PCB space, reduces external component count, allows use of cheap connectors and requires fewer PCB (printed circuit board) layers. Benefits for end users include up to 80% longer battery lifetime, more colorful effects and smoother running animations.

Although it is relatively straightforward to design a basic LED driver for a general lighting application, it becomes far more complex when additional functionality such as phase cut dimming and power factor correction are also required. A non-dimming LED driver with no power factor correction generally consists of an off line switching power supply configured to regulate the output at a constant current. This is not much different from a standar...
