• Choice of Three Minimum
Luminous Intensities
• Viewing Angles: 23˚ and 30˚
• Superior Resistance to

Description
These high intensity bluish-green
LEDs are based on InGaN
material technology. InGaN is the
most efficient and cost effective
material for LEDs in the blue and
green region of the spectrum.
The 505 nm typical dominant
wavelength matches international
specifications for green traffic
signals.
These LED lamps are untinted,
nondiffused, T-1 3/4 packages
incorporating second generation
optics producing well defined
spatial radiation patterns at
specific viewing cone angles.
These lamps are made with an
advanced optical grade epoxy,
offering superior temperature
and moisture resistance in
outdoor signal and sign
applications. The package epoxy
contains both UV-a and UV-b
inhibitors to reduce the effects of
long term exposure to direct
sunlight.
These lamps are available in two
viewing angle options and two
package options to give the
designer flexibility with optical
design and device mounting.
Each part type includes three
choices for minimum luminous
intensity.
Benefits
• Viewing Angles Match
Traffic Signal Requirements
• Superior Performance in
Outdoor Environments
• Suitable for Autoinsertion
onto PC Boards
Applications
• Traffic Signals
• Commercial Outdoor Signs
• Automotive Interior Lights
CAUTION:
HLMP-CExx LEDs are Class 1 ESD sensitive. Please observe appropriate precautions
during handling and processing. Refer to Hewlett-Packard Application Note AN-1142 for
additional details.

Notes:
1. All InGaN LEDs represented here are IEC825 Class 2. See
Application Brief 1009
and
1015
for details.
2. The dominant wavelength
λd
is derived from the CIE Chromaticity Diagram and represents the perceived color of the device.
3.
θ
1/2
is the off-axis angle where the luminous intensity is 1/2 the peak intensity.
4. Luminous efficacy is the ratio of luminous flux to radiant flux.
