Avago Technologies has introduced a high-brightness green auto focus auxiliary flash light emitting diode (LED) to assist the auto focusing function in digital still cameras used in low ambient light conditions. With a footprint about the size of a pencil eraser, Avago's ASMT-FG10 auto focus auxiliary flash LED provides designers of digital still cameras with a low-cost alternative to conventional infrared (IR) auxiliary auto focus solutions.

This compact green LED lamp is easy to install, offers the highest brightness and most compact package in the industry, and targets digital camera designers who need a cost-effective solution that can perform auto focusing functions in dark environments.

Digital still cameras have twice the sensitivity when responding to the colour green than other colours, due to the availability of more photo diodes allocated for green in each pixel. Avago's ASMT-FG10 surface mount (SMT) LED allows designers of digital cameras to package far greater functionality per square-inch of printed circuit board space while achieving superior performance in terms of brightness and power consumption. In addition, this SMT LED package simplifies the assembly process. As a result, design engineers can expect cost savings and better performance of the overall camera system.

Avago's ASMT-FG10 green (530nm) Indium Gallium Nitrate (InGaN) dome LED lamp uses an un-tinted, non-diffused lens to provide high luminous intensity within a narrow radiation pattern. The ASMT-FG10 incorporates an encapsulated LED chip on an axial lead frame to form a moulded epoxy lamp package with six bended leads for surface mounting. The InGaN material used in this LED lamp has a very high luminous efficiency and is capable of producing high light output over a wide range of drive currents. The narrow angle SMT lamp package is suitable for digital cameras that require long distance illumination and a narrow beam pattern.
