Agilent HSMx-C540
Oval Lens High Performance
Surface Mount LEDs
Data Sheet
Description
These high performance
HSMx-C540 surface mount LEDs
are specifically designed for indoor
full color signs and passenger infor-
mation signs. The oval shaped
radiation pattern (40
x 100
) and
high luminous intensity ensure that
these devices are excellent for wide
field of view indoor applications.
These lamps have a very smooth
matched radiation pattern that
ensures consistent color mixing in
full color applications, and message
uniformity across the viewing angle
of the sign.
High efficiency LED dice are used
in these LED components. InGaN
(Indium Gallium Nitride) for green
and blue and AlInGaP (Aluminium
Indium Gallium Phosphide) for red
LED Part Numbers HSMA-C540, HSMC-C540,
HSMM-C540, HSMN-C540, HSMU-C540, HSMZ-C540

CAUTION: HSMM-C540 and HSMN-C540 LEDs are Class 1 ESD sensitive. Please observe appropriate precautions
during handling and processing. Refer to Agilent Technologies Application Note AN-1142 for additional details.
and amber are capable of produc-
ing high light output.
The HSMx-C540 has an industry
standard 2.0 x 1.25 mm footprint
that is excellent for all-around use.
These solid state surface mount
LEDs are designed with a reflector
cup and oval shape dome which
provides directional lighting. The
reflector cup focuses the light
more efficiently to provide higher
intensity compared to a
nonreflector cup equivalent part.
The oval dome produces oval
radiation pattern for wide field of
view indoor applications.
All packages are compatible with
IR soldering process and are
shipped in tape and reel with
3000 units per reel.

Notes:
1. The luminous intensity, I
V
, is measured at the peak of the spatial radiation pattern, which may not be aligned with the mechanical axis of the
lamp package.
2. The dominant wavelength,
d
, is derived from the CIE Chromatically Diagram and represents the perceived color of the device.
3.
1/2
is the off-axis angle where the luminous intensity is 1/2 the peak intensity.
