Avago’s small-footprint auto-focus auxiliary flash LEDs enable thinner digital cameras

Avago Technologies has launched two series of compact LEDs that reduce space requirements for designing auto-focus auxiliary flash functionality into digital cameras. The ASMT-FJ70 and ASMT-FG70 devices are available in what is claimed to be one of the market’s thinnest, smallest-footprint packages for LEDs with the brightness needed for auto-focus functionality in dark settings.

ASMT-Fx70 LEDs are available in an environmentally friendly 3.6mm-long by 3.2mm-wide by 3.4mm-high surface-mount package that helps to meet market demand for thinner digital cameras. The LEDs use a clear, non-diffused lens to provide high luminous intensity within a narrow radiation pattern, providing smooth, consistent optical performance for precise auto-focus functionality. ASMT-FJ70 devices are orange and ASMT-FG70 devices are reckoned to be the industry’s first green auxiliary flash LEDs in this size range.

“Digital cameras continue to shrink in size while growing in functionality and capacity, and our new auxiliary flash LEDs address this challenge by allowing designers to pack in greater functionality per square inch of the camera,” says Francis Khor, director of marketing for optoelectronics products. “The Avago ASMT-Fx70 LEDs provide the best of both worlds, as they offer a small design footprint without sacrificing auto-flash performance,” he adds.

The ASMT-FJ70 devices use aluminum indium gallium phosphide (AlInGaP) material and feature a 12° viewing angle, while the ASMT-FG70 devices use indium gallium nitride (InGaN) material and provide a 14° viewing angle. Both technologies have very high luminous efficiency, producing high light output over a wide range of drive currents. The narrow viewing angles deliver the long-distance illumination and narrow beam pattern required for auto-focus auxiliary flash functionality.

The ASMT-FJ70 and ASMT-FG70 also feature a lead (Pb)-free and RoHS 6 compliant package. The LEDs are shipped in tape and reel to facilitate pick & place manufacturing. The operating temperature range is -40°C to +85°C.

Pricing is $0.45 each for the orange ASMT-FJ70 LEDs and $0.60 each for the green ASMT-FG70 LEDs, both in minimum quantities of 10,000 pieces.
