NEW YORK, NY (May 8, 2007) – Providing lighting design engineers with a complete LED

solution, from designing to manufacturing to testing, TT electronics OPTEK Technology’s

in-house visible LED laboratory features an array of equipment and other resources to

accurately assess products ranging from single LEDs to complex power LED assemblies.

According to Richard Saffa, vice president of OPTEK Technology’s Visible LED Business

Unit, a customer approached OPTEK with the need to convert an existing halogen lamp to

an LED assembly. “With the use of the equipment in our lab, we were able to match the

spot size, luminous flux and uniformity of the halogen lamp to the assembly, as well as

increase the optical efficiency,” said Saffa. “As a result, we were able to recommend a

custom designed LED solution that fit exactly what the customer needed.”

Each characteristic of an LED or LED assembly has significant implications, depending on

the application, Saffa continued. OPTEK’s lab has the equipment to assess variations over

time and junction temperature in most common optical parameters, including dominant

wavelength, color temperature and color rendering index.

OPTEK’s visible LED laboratory equipment includes a large one-meter integrating sphere

used to determine color temperature (CCT) and brightness (TLF); a thermal imaging

camera to provide data for optimizing thermal management designs which enhance the

lifespan and light output of power LED assemblies; a scanning electron microscope with a

Princeton Gamma Tech X-ray analyzer for failure analysis; a luminous flux and wavelength

tester to verify color and hue; and a spectroradiometer system accommodating

wavelengths from 200nm to 780nm measuring the radiometric and photometric

characteristics of LED assemblies of all shapes. The spectroradiometer system also

includes a goniometer, CIE 127 Publication Condition A&B tube, and a 6” integrating


OPTEK will also provide customers with full comparison data, and invites them to be on-

site to witness the testing first hand.
