October 14, 2005, Carrollton, TX--Expanding the scope of their visible LED business into the solid-state lighting marketplace, Optek Technology has signed a joint research and development, manufacturing and marketing relationship agreement with Lednium, an Australian-based LED technology company.

Under terms of the agreement, Optek will develop a series of solid state lighting products using the Lednium packaging technology. Designated the Optek Lednium Series, the new product line will include single-chip "cup" packaged discrete LED lighting units as well as multi-chip geodesic dome shaped 10W LED assemblies. Available colors will include white, blue, green, amber, and red, along with color combinations such as RGB.

Optek established a visible LED business unit earlier this year, and currently offers a comprehensive product line that includes industry standard high brightness and high power LEDs.

Through a focused research initiative, Lednium developed the world's first three-dimensional LED die platform for both white and monocolor LEDs, as well as end-product LED assemblies for applications ranging from architectural lighting to automotive aftermarket assemblies for tractor-trailer exterior taillights and clearance lights.

Optek and Lednium plan to jointly develop other wavelength technologies to be packaged for various markets, from medical applications to surveillance and security equipment. Applications for the Optek Lednium Series include architectural lighting, automotive, aviation, display, entertainment, gaming and vending machines, marine, military, signs and signals, variable message signs and general illumination.
