More brightness for InGaN LEDs
Agilent Technologies has expanded its line of extra-bright InGaN LEDs for outdoor electronic signs and signals with new devices in 4 and 5mm domed through-hole packages with oval radiation patterns.
Agilent Technologies has expanded its line of extra-bright InGaN (indium gallium nitride) LEDs for the outdoor electronic sign and signals market by adding new devices in 4mm (T-1) and 5mm (T-1.75) domed through-hole packages with oval radiation patterns These are the company's brightest InGaN LEDs, with brightness equivalent to the industry's leading supplier

Hot-pluggable transceiver for Fibre Channel
Agilent Technologies has announced volume availability of its 2Gbit/s small-form-pluggable (SFP) fibre-optic transceiver for Fibre Channel storage area networks (SANs).
The combination of high brightness and weather-resistant packaging with an oval radiation pattern makes these LEDs ideal for applications such as full-colour outdoor video displays, stadium scoreboards and other variable message signs.
The oval-shaped radiation pattern casts a wider field-of-view with a higher luminosity than standard LEDs, making the devices ideal for outdoor applications where readability in sunlight is essential.
These lamps have very smooth, matched radiation patterns, ensuring consistent colour mixing in full-colour applications and uniformity across the viewing angle of the sign.
Agilent's blue and green LEDs are based on the most efficient and cost-effective flip-chip InGaN material technology.
The 470nm typical dominant wavelength for blue and 521nm typical wavelength for green are well suited to colour mixing in full-colour signs.
These extra-bright InGaN lamps feature 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 ultraviolet-resistant blend.
This means the lamps perform with high reliability over the -40 to +85C temperature range and are protected from UV radiation and humid environments.
These LEDs are specifically optimised for full-colour video and information signs.
Samples and production quantities (four-week guaranteed lead-time) are available now through Agilent's direct sales channel and worldwide distribution partners. Request a free brochure from Avago Technologies ...
