Avago expands super half-watt PLCC-4 SMT LEDs to full range of colors

Avago Technologies of San Jose, CA, USA has supplemented its ASMT-QxBE series of super half-watt (0.5W) power PLCC-4 surface-mount (SMT) LEDs for use in automotive and electronic sign applications with four new colors: a brighter cool white, and warm white, blue and green colors (making a full range of colors, together with the existing white ASMT-QWB2, amber ASMT-QAB2, red-orange ASMT-QHB2 and red ASMT-QRB2 LEDs).

The LEDs feature what Avago claims is the industry’s smallest package size and a wide 120º viewing angle, and have been optimized for long operating life under severe environmental conditions. The ASMT-QxBE series of high-brightness power LEDs has been designed to dissipate heat more efficiently in order to provide better thermal management and consistent light output. Typical luminous flux is 9.8-17 lumens at 150mA drive currents. The junction temperature is a high 125ºC, the thermal resistance is a low 60ºC/W junction to pin, and the operating temperature range is –40ºC to +110ºC.

The high-efficiency 40lm/W cool white (ASMT-QWBE), 33lm/W warm white (ASMT-QYBE), 10lm/W blue (ASMT-QBBE) and 35lm/W green (ASMT-QGBE) SMT LEDs can be used in automotive applications for backlighting dashboards, dome and map lighting, puddle lamps, rear reverse lamp indicator lighting, and license plate illumination. The LEDs can also be used for decorative lighting in general lighting applications, channel lettering in electronic sign and signals (ESS) applications , and for backlighting instrument panels and displays in industrial equipment, office automation and home appliance applications. Also, the high-brightness output per LED and small package footprint (3.2mm x 2.8mm x 1.9mm) provide greater flexibility in designing the size, shape and appearance of lighting assemblies, the firm clams.
