High Brightness SMT Oval LED Lamps
Amber, Red, Green and Blue
Data Sheet
Description
The new Avago ALMD-Lx36 oval LED series has the same
or just slightly less luminous intensity than conventional
high brightness, through-hole LEDs.
The new oval LED lamps can be assembled using common
SMT assembly processes and are compatible with indus-
trial reflow soldering processes.
The LEDs are made with an advanced optical grade epoxy
for superior performance in outdoor sign applications.
The surface mount Oval LEDs are specifically designed for
full color/video signs and indoor or outdoor passenger
information sign applications.
For easy pick and place assembly, the LEDs are shipped
in EIA-compliant tape and reel. Every reel is shipped from
a single intensity and color bin– except the red color–for
better uniformity.

CAUTION:
InGaN devices are Class 1C HBM ESD sensitive, AlInGaP devices are Class 1B ESD sensitive per JEDEC Standard.
Please observe appropriate precautions during handling and processing. Refer to Application Note AN-1142 for additional details.
CAUTION:
Customer is advised to keep the LED in the MBB when not in use as prolonged exposure to environment might cause the
silver plated leads to tarnish, which might cause difficulties in soldering.

Notes:
1. The luminous intensity is measured on the mechanical axis of the lamp package and it is tested with pulsing condition.
2. The optical axis is closely aligned with the package mechanical axis.
3. Dominant wavelength, λd, is derived from the CIE Chromaticity Diagram and represents the color of the lamp.
4.
T½
is the off-axis angle where the luminous intensity is half the on-axis intensity.
5. Tolerance for each bin limit is ± 15%
