Single LED packages through complex power LED assemblies are evaluated at the lab, with customers encouraged to observe the in-house tests. A large one-meter integrating sphere determines color temperature (CCT) and brightness (TLF). A thermal imaging camera provides data for optimizing thermal management designs, used to extend the lifespan and light output of power LED assemblies. Other equipment includes a scanning electron microscope (SEM) with a Princeton gamma tech X-ray analyzer for failure analysis, and luminous flux and wavelength tester, a spectroradiometer system, and a goniometer. OPTEK provides comparison data for redesigns or LEDs designed to replace conventional lighting sources.
