Extra-bright white LEDs

Supplier News

AGILENT Technologies has introduced a series of extra-bright white InGaN (indium gallium nitride) LEDs targeted for the electronic sign and signals market.

These are the company's brightest white InGaN LEDs and enable Agilent to address a wider range of indoor and outdoor applications that require the brightest LEDs possible.

The combination of high brightness and weather-resistant packaging makes these LEDs ideal for applications such as gaming machines, traffic signals and signs, stadium scoreboards, advertising and other variable message signs.

The HLMP-CWxx circular-pattern and HLMP-FWxx flat-top extra-bright white LED lamps, from Agilent's Semiconductor Products Group, are available in 15-, 23-, 30-, 50-, 70- and 85-degree circular viewing angles.

The spatial 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.

Agilent's white LEDs are based on efficient and cost-effective flip-chip InGaN material technology. These extra-bright white InGaN lamps are supplied in 5mm (T-1 3/4) through-hole packages and combine Agilent's 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.
