Avago Technologies Introduces New Extra Bright II Oval Red, Green and Blue LEDs for Electronic Signs and Signals Applications

Avago Technologies today announced a new series of Extra Bright II oval Red, Green and Blue light emitting diodes (LEDs) for the electronic signs and signals (ESS) market.  Avago¡¯s series of 4 and 5 mm oval through-hole LED lamps have been specifically designed for use in full color ESS applications such as passenger signs, variable message signs, scoreboards and channel lighting.  Avago is a leading supplier of analog interface components for communications, industrial and consumer applications.

Avago¡¯s HLMP-Lx63 (4 mm) and HLMP-Hx63 (5 mm) series of LEDs provide an oval shaped radiation pattern, a wide viewing angle and high illumination intensity to make display characters viewable from any angle in bright sunlight.  Moreover, these LED lamps have a very smooth, matched radiation pattern to ensure consistent color mixing in full color applications.  Each lamp is made with advanced optical grade epoxy to offer superior high temperature and high moisture resistance in outdoor ESS applications.

Designers of electronic signs and signals are seeking higher brightness levels to reduce the number of LEDs in a cluster.  With Avago¡¯s HLMP-Lx63 and HLMP-Hx63 series of extra-bright 4 and 5 mm oval through-hole LED lamps, electronic signs can be designed using fewer individual LEDs to provide equivalent brightness.  Alternatively, signs can be designed with the same number of LEDs, providing substantially higher brightness levels for better readability and contrast.  The lead spacing and packages are compatible with conventional high-brightness 4 and 5 mm standard and miniature oval-pattern LED lamps.

The extra-bright HLMP-Lx63 and HLMP-Hx63 through-hole oval LED lamps are supplied in Avago¡¯s precision optical performance molded packages to offer high brightness and low power consumption.  The packaging design coupled with carefully selected materials allows the lamps to perform with high reliability in a wide temperature range, which is crucial for outdoor applications where the LED is exposed directly to ultraviolet radiation and humid environments.
