Features
• Smooth, Consistent Spatial
Radiation Patterns
• Viewing Angles: 15˚ and 30˚
• High Luminous Output
• Colors: 472 nm Blue,
526 nm Green
• Superior Resistance to
Moisture
Description
These high intensity blue and
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 472 nm typical dominant
wavelength for blue and 526 nm
typical dominant wavelength for
green are well suited to color
mixing in full color signs.
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 high maximum
LED junction temperature limit of
+130˚C enables high
temperature operation in bright
sunlight conditions. 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.
Benefits
• Superior Performance in
Outdoor Environments
• Wavelengths Suitable for
Color Mixing in Full Color
(RGB) Signs
• Color to Color Consistency
of Radiation Patterns (CBxx
to CMxx to HLMP-DGxx
Red) Enables Sign Color
Uniformity at All Angles
Applications
•
•
•
•
Commercial Outdoor Signs
Automotive Interior Lights
Front Panel Indicators
Front Panel Backlighting
CAUTION:
HLMP-CBxx LEDs and -CMxx’s 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
λ
d
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.
