Available in red, red-orange and amber, the new LEDs fill the need for mid-power illumination capabilities between the current Agilent PLCC-4 products, operating at up to 200 mW power levels, and Lumileds Lighting's Luxeon LED light sources that operate at power levels of 1 W and higher.

The use of Lumileds’ TS AlInGaP (transparent-substrate aluminum indium gallium phosphide) LED die enables the new LEDs to produce higher luminous flux output than other PLCC-4 LEDs on the market, according to Soo-Ghee Lee, vice president and general manager for the optoelectronic products division in Agilent's semiconductor products group.

The Envisium Power PLCC-4 SMT LEDs have a substrate consisting of a molded plastic reflector on top of a bent lead frame. The die is attached within the reflector cavity, and the cavity is encapsulated by an Agilent-proprietary epoxy blend. The package design and careful selection of component materials is said to allow the LEDs to perform reliably over the -40 C to +100 C temperature range. The package can be driven at high current, and is compatible with both IR-solder reflow and through-the-wave soldering.
