Small-footprint auto-focus auxiliary flash LEDs enable thinner digital cameras
Avago has debuted two series of compact LEDs that reduce space requirements for designing auto-focus auxiliary flash functionality into digital cameras. The new ASMT-FJ70 and ASMT-FG70 devices are available in one of the market’s thinnest, smallest-footprint packages for LEDs with the brightness needed for auto-focus functionality in dark settings.
The ASMT-Fx70 LEDs are available in a tiny 3.6 (L) by 3.2 (W) by 3.4 (H) mm surface-mount package that helps 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. The ASMT-FJ70 devices are orange and the ASMT-FG70 devices are the industry’s first green auxiliary flash LEDs in this size range.
The ASMT-FJ70 devices use Aluminum Indium Gallium Phosphate (AlInGaP) material technology and feature a 12 degree viewing angle, while the ASMT-FG70 devices use Indium Gallium Nitride (InGaN) material technology and provide a 14 degree 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.
