SAN JOSE, Calif., Jan. 18, 2012 — Avago Technologies has announced two series of compact LEDs that reduce space requirements for designing autofocus auxiliary flash functionality into digital cameras. The ASMT-FJ70 and ASMT-FG70 devices are available in a thin small-footprint package with the brightness needed for autofocus in dark settings.
The LEDs are available in an environmentally friendly 3.6 × 3.2 × 3.4-mm surface-mount package that helps meet market demand for thinner digital cameras. They use a clear, nondiffused lens to produce high luminous intensity within a narrow radiation pattern, providing smooth, consistent optical performance for precise autofocus. The ASMT-FJ70 devices are orange, and the ASMT-FG70 devices are green auxiliary flash LEDs.
Digital cameras continue to shrink in size while growing in functionality and capacity, and the new auxiliary flash LEDs address this challenge by allowing designers to pack in greater functionality per square inch of the camera.
The ASMT-FJ70 devices use AlInGaP material technology and feature a 12° viewing angle, while the ASMT-FG70 devices use InGaN material technology and provide a 14° viewing angle. Both technologies have 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 autofocus auxiliary flash.
The LEDS are supplied in a lead-free and RoHS 6-compliant package, are shipped in tape and reel to facilitate pick-and-place manufacturing, and operate over a temperature range from −40 to 85 °C.
