5/12/2004 - Agilent Technologies Inc. (NYSE: A) introduced a series of extra-bright InGaN (indium gallium nitride) LEDs targeted for the outdoor electronic sign and signals market. These are the company's brightest InGaN LEDs and enable Agilent to expand its range of applications to include full-color signs and mono-color traffic signals that require the brightest LEDs possible. The combination of high brightness and weather-resistant packaging makes these LEDs ideal for applications such as traffic signals, pedestrian crossing signs, speed limit and exit signs, stadium scoreboards, advertising and other variable message signs.
The HLMP-Cxxx circular-pattern and HLMP-Hxxx oval-pattern extra-bright LED lamps, from Agilent's Semiconductor Products Group, are available in blue, green and cyan, and in 15-, 23- and 30-degree circular viewing angles. The blue and green versions are available with 40-degree by 100-degree oval viewing angles, specifically designed for full-color video and passenger information signs. The oval-shaped radiation pattern and high luminosity make these devices 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, and uniformity across the viewing angle of the sign.
"Our new series of extra-bright InGaN LED lamps provide superior performance and significantly enhance our capability to capture a growing share of the electronic signs and signals applications," said Soo-Ghee Lee, vice president and general manager of Agilent's Optoelectronic Products Division. "As an LED leader, we're committed to providing our customers the highest-quality products in volume and at competitive prices."
Agilent's blue and green LEDs are based on the most efficient and cost-effective flip-chip InGaN material technology. The 470 nm typical dominant wavelength for blue and 521 nm typical wavelength for green are well suited to color mixing in full-color signs. The 505 nm typical dominant wavelength for cyan is suitable for traffic-signal applications. These extra-bright InGaN lamps are supplied in 5 mm (T-1 3/4) through-hole packages and combine Agilent's most advanced through-hole packaging technology to ensure maximum light extraction from the die. The die is attached within the reflector cavity, and the cavity is encapsulated by Agilent's proprietary epoxy blend. This means the lamps perform with high reliability over the -40 C to +85 C temperature range and are protected from UV radiation and humid environments.
