ENAC Accredited, Photobiological safety
Photobiological safety testing of luminaires, lamps, and other lighting devices according to
UNE-EN 62471
and photobiological risk assessment according to
IEC 62471-7
and
IEC TR 62778.
Optical radiation is easily absorbed absorbed by the outer layers of the human body, with the skin and eyes being the organs most at risk of damage due to exposure to optical radiation.
Therefore, three exposure scenarios must be considered: exposure to the skin, to the front of the eye (cornea, conjunctiva, and lens), and to the retina. These effects must be assessed considering the emission limits provided by the Artificial Optical Radiation Directive (2006/25/EC).
The results provided in a photobiological safety test report (blue light risk) are the risk group (UNE-EN 62471), compliance with the permissible limits according to its application group (IEC 62471-7), or the calculation of the distance and cut-off illuminance, if necessary (IEC/TR 62778).
Although the IEC/TR 62778 technical report is canceled and there is no document replacing it, the calculations defined therein are referenced in other safety standards.
The procedure for evaluating a specific product will depend on the needs and the conditions it must meet. At candelTEC, we can help you determine the best way to evaluate it.
Our reports always provide the test and calculation results along with their corresponding
measurement uncertainties.
