OmniVision Technologies, Inc. (NASDAQ: OVTI), a leading developer of advanced digital imaging solutions, today introduced the OV7727, a top-of-the-line VGA sensor for the high-end ultra-thin notebook market. The 1/13-inch OV7727 is the first VGA sensor built with OmniBSI™ backside illumination technology. It combines extremely strong performance and sensitivity with an ultra-compact form factor, enabling camera integration with sub-2 mm liquid ...

OMC has introduced a range of Light Engines designed to simplify LED lighting design. SPECTRALUX light engines enable luminaire manufacturers and other lighting users to produce a vast range of products that deliver excellent illumination and have an extremely long life time at particularly high luminous efficiencies which in many cases exceed 100lm/W.

OMC can now offer bespoke backlights for LCDs based on a new emitter design that provides the brightness of a dual chip emitter but requires only the forward voltage of single chip solution. Therefore, for the first time, users can drive OMC’s white and blue Profiled Backlight range from a 5V source, which OMC say is becoming ever more desirable in modern applications.

In 2011, LED supply exceeded demand by 30% due to poor LED TV sales and slow growth in LED lighting. However, this gap is closing in 2012 due to recovering backlight demand and increasing demand for lighting. According to the recent NPD DisplaySearch Quarterly LED Supply/Demand Market Forecast Report, the glut will be 19% in Q1’12 and will drop to 16% in Q2’12.

New OSRAM Ostar Stage LEDs from OSRAM Opto Semiconductors are making spotlights more compact and brighter than ever by means of a much flatter profile, an extremely narrow beam angle, and significantly higher luminance. These LEDs are ideal for moveable stage lights, known as moving heads that provide powerful light beams for rock concerts and other events.

This circuit consists of a power section optimized to deliver a total of 160mA to the LED array. The first string is controlled by the feedback loop to 20mA. The remaining strings are controlled by the current mirrors created by the PNP transistors at the top of each string.

DSEM has launched the JLED series which is the first LED array with integrated optics. The 10W product has achieve >110lm/W for cool white solution. The integrated optics proves DSEM has grown to next level of the technology in their LED array.

Maxim Integrated Products introduces the MAX9635, a fully integrated digital ambient-light sensor (ALS) with a unique adaptive gain block. Designed using the Company's proprietary BiCMOS technology, this device integrates two photodiodes, an ADC, and all necessary digital functionality into a tiny 2mm x 2mm package. This integrated solution saves valuable space in tight enclosures while delivering the industry's highest performance. The MAX9635 c...

Sharp's new 10W Mini Zeni series radiates with even more efficiency, whilst retaining very good light quality (CRI values of up to 87) and a long service life with its compact and cost-effective design.

S Components today announced it is the first distributor to be stocking the latest OLED lighting solutions from Osram Opto Semiconductors. The 'instant on, dimmable' additions to the Orbeos range of OLED lighting components represent the very latest in lighting flexibility and are available for same day despatch.
