Spectrometer adds dimension to goniometric characterization of SSL lamps and luminaires

While photodetectors have long been used alongside goniometers to characterize light sources, PASI MANNINEN and MIKOLAJ PRZYBYLA explain that a GONIO-SPECTROMETER system enables collection of a more robust set of parametric data for LED-based products. Published on Sep 3, 2015 in LEDs MAGAZINE by Mikolaj Przybyla nad Pasi Maninen   Goniometers are a class of optical [...]

White LED light sources – quality and colorimetric characteristics

Optical radiation in the visible range, primarily white light with correlated colour temperature ranging from 3000 to 6500 K, can be emitted by electroluminescence diodes available in different technologies. For this reasons LED modules, integrated LED lamps and LED luminaries differ with respect to the quantity and quality of emitted radiation. Reliable measurements and comparisons [...]
