Description
These Precision Optical
Performance Oval LEDs are
specifically designed for full
color/video and passenger
information signs. The oval
shaped radiation pattern
(35°x70°) and high luminous
intensity ensure that these
devices are excellent for wide
field of view outdoor application
where a wide viewing angle and
readability in sunlight are
essential. These lamps have very
smooth, matched radiation
patterns ensuring consistent
color mixing in full color
applications, message uniformity
across the viewing angle of the
sign.
High efficiency LED material is
used in these lamps: Aluminum
Indium Gallium Phosphide
(AlInGaP) for amber and red,
and Indium Gallium Nitride
(InGaN) for blue and green. Each
lamp is made with an advance
optical grade epoxy offering
superior high temperature and
high moisture resistance in
outdoor applications. The
package epoxy contains both
UV-A and UV-B inhibitors to
reduce the effects of long term
exposure to direct sunlight.
Designers can select parallel or
perpendicular orientation. Both
lamps are available in tinted
version.
CAUTION: The blue and green LEDs are Class 1 ESD sensitive. Please observe appropriate
precautions during handling and processing. Refer to Agilent Application Note AN-1142 for
additional details.
