OPTEK Technology�s LED lab offers a comprehensive range of services and customized testing capabilities for the design and development of solid-state lighting applications, providing design engineers of LED light engines with the facility to perform the precision testing required for uniform color temperature and intensity. Specifically built for the testing and analysis of LED light engines, OPTEK�s lab capabilities feature 100 percent color temperature and/or intensity screening for precision binning specifications.

OPTEK�s vice-president for Integrated Solutions, Roland Chapa explains, �Our lab�s ability to provide screening for LED binning smaller than ANSI standards enables our customers to deliver uniform color temperature and consistent color for applications where lighting aesthetics are critical.? He adds, �This level of precision screening and testing is vital for customers who require a specific color light associated with their brand or corporate image, and it�s a capability that typical contract manufacturers are unable to provide.?

OPTEK�s LED test lab includes the following advanced equipment for precise measurement and characterization of radiometric and photometric characteristics:

Integrating spheres to determine a light source�s correlated color temperature (CCT) and luminosity/total luminous flux (TLF); radiation spectrometer system, consisting of a 6-inch integrating sphere, a goniometer to measure the spatial distribution of light visible to the human eye at a specific angular position; luminous flux and wavelength test equipment to verify light output and spectral bandwidth; Infrared thermal imaging camera to provide data for optimizing thermal management of LED assemblies; Princeton Gamma-Tech scanning electron microscope (SEM) X-ray analyzer to provide data for failure analysis.

OPTEK�s solid-state lighting solutions are extensively utilized in commercial and institutional lighting, which includes backlighting of displays, interior and exterior automotive lighting, general illumination, street and market lights, and many other specialty applications.
