San Jose, Calif. 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 when used in low ambient light conditions. The ASMT-FG10 flash LED offers a small footprint, measuring 4.8 x 4.8 x 5.33 mm.
Touted as a low-cost alternative to conventional infrared (IR) auxiliary auto focus solutions, the ASMT-FG10 compact green LED lamp is said to provide the highest brightness and smallest package in the industry. The narrow angle SMT lamp package is suitable for digital cameras that require long distance illumination and a narrow beam pattern. Digital still cameras have twice the sensitivity when responding to the color green than other colors, due to the availability of more photo diodes allocated for green in each pixel, said the company.
The ASMT-FG10 green (530nm) Indium Gallium Nitride (InGaN) dome LED lamp uses an un-tinted, non-diffused lens to provide high luminous intensity within a narrow radiation pattern. It incorporates an encapsulated LED chip on an axial leadframe to form a molded epoxy lamp package with six bended leads for surface mounting. The InGaN material has a very high luminous efficiency and is capable of producing high light output over a wide range of drive currents, said the company.
The easy to install ASMT-FG10 also simplifies the assembly process, which is said to result in a cost savings and better overall performance of the camera. It also features a six-degree viewing angle and is compatible with 2x solder reflow process. It meets IEC/EN 60825-1 Eye Safety Class 1 requirement. The device is RoHS compliant.
