Tiny half-watt LEDs add more colours

Avago Technologies product story

The high brightness output per LED and small package footprint provide lighting designers with greater flexibility in designing the size, shape and appearance of lighting assemblies.
Avago Technologies has added four new colours to its series of super 0.5W power PLCC-4 surface-mount light emitting diodes for automotive and electronic sign applications.
The new additions to Avago's ASMT-QxBE series include a brighter cool white, as well as warm white, blue and green colours.
These new LEDs from Avago feature the industry's smallest package size, a wide 120-degree viewing angle, and have been optimised for long operating life under severe environmental conditions.
The addition of these new LEDs will enable Avago to offer a full range of colours to its existing 0.5W PLCC-4 LED customers.
The ASMT-QxBE Power LED series of high-brightness LEDs have been designed to dissipate heat more efficiently to provide superior thermal management and consistent light output.
Avago's 0.5W cool white (ASMT-QWBE), warm white (ASMT-QYBE), blue (ASMT-QBBE) and green (ASMT-QGBE) series of SMT LEDs can be used for backlighting dashboards, dome and map lighting, puddle lamps, rear reverse lamp indicator lighting and licence plate illumination in automotive applications.
The ASMT-QxBE series can also be used for decorative lighting in general lighting applications, channel lettering in ESS applications, and for backlighting instrument panels and displays in industrial equipment, office automation and home appliance applications.
Moreover, the high brightness output per LED and small package footprint (3.2 x 2.8 x 1.9mm) of Avago's 0.5W power LED series provide lighting designers with greater flexibility in designing the size, shape and appearance of lighting assemblies.
In addition to the combination of high-brightness, long life and compact size, Avago's 0.5W power PLCC-4 series of LEDs provide two significant advantages in the production environment.
They can be easily soldered using conventional surface mount techniques to minimise production costs, and the package is qualified to a Joint Electron Device Engineering Council (JEDEC) moisture sensitive level (MSL) rating of 2A.
For manufacturers, this rating means that the 0.5W power PLCC-4 LEDs can be kept in the open air (30C, 60% RH) for up to four weeks after being removed from its sealed package without the need to remove absorbed moisture.
Avago's ASMT-QxBE series feature typical luminous flux of 9.8 to 17 lumen at 150mA drive currents.
Previously announced 0.5W power PLCC-4 LED colours and corresponding part numbers for the power PLCC-4 series are white (ASMT-QWB2), amber (ASMT-QAB2), red-orange (ASMT-QHB2) and red (ASMT-QRB2).
