QUALILAB s.r.l. has a state of the art spectrometer (double monochromator) that gives a reliable source of data that defines the radiometric performance and safety of luminaires and light sources. Over the past years, safety legislation relating to LED devices has become somewhat more complicate due to not only change of horizontal product safety standard, but also the impending implementation of the artificial optical radiation directive, concerned with worker exposure. EN 62471:2008 gives guidance for evaluating the photobiological safety of lamps and lamp systems emitting optical radiation in the range 200nm to 3000nm and provides exposure limits and a framework of classification.
Sources are classified in the following four groups according to hazard, based on permissible exposure time before hazard exceeded:
EXEMPT - RISK GROUP 1 - RISK GROUP 2 - RISK GROUP 3
norms and standards: EN 62471 / directive 2006/25/EC / IESNA RP27
instrument: spectrometer double-monochromator from 200nm to 3000nm
derived measurements: CCT - correlated color temperature, CRI - color rendering index, color coordinates
