HLMP-SD11 4mm Oval Precision Optical Performance Best Value AlInGaP LED Lamps

Currently Viewing:

These Precision Optical Performance Oval LEDs are specifically designed for Full Color/Video and Passenger Information signs. The Oval shaped radiation pattern (60 degrees x 120 degrees) and high luminous intensity ensure that these devices are excellent for wide field of view outdoor applications 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: Higher performance of Aluminum Indium Gallium Phosphide (AlInGaP II). Each lamp is made with an advanced 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.
