Description
• Colors: Amber and Red
The LED Light Source is based
on clustered High Flux AlInGaP
LEDs in a series/parallel circuit,
assembled onto a metal core
printed circuit board (MCPCB).
The reliable connections provide
mechanical sturdiness and good
electrical and thermal
conductivity. This component is
designed and manufactured by
LumiLeds Lighting, and sold and
supported by Hewlett-Packard.

on new packaging technology
and large LED chip sizes. These
lamps offer greater efficiency and
reliability at high current than
traditional LEDs.
Benefits
• Highest Luminous Flux per
Surface Area for any LED
Source
• Radiation Pattern Provides
Uniform Luminance across
Entry Plane of Secondary
Optics
Built with the same aluminum
indium gallium phosphide
(AlInGaP) LED technology as
Hewlett-Packard’s Precision
Optical Performance lamps,
these products deliver a luminous
efficiency of approximately 18
lumen per watt. Superior
Designers who are seeking a
reliable solid state light source
offering a very high luminous
output will experience reduced
design time and enhanced
reliability by this preassembled
LED array. While the LED Light
Source is optimized for use in
traffic signals, its small size and
versatility make it a good choice
for many applications.
