Photobiological safety

ENAC Accredited, Photobiological safety

Photobiological safety test on luminaires, lamps and other lighting devices, according to the UNE-EN 62471 standard and according to the technical report IEC TR 62778.

Optical radiation is easily absorbed by the outer layers of the human body: the skin and eyes being the organs that are most at risk of some type of damage due to exposure to optical radiation. 

Having this fact in mind, three exposure scenarios should be considered: exposure of the skin, of the frontal surface of the eye (cornea, conjunctiva, and lens) and of the retina. The effects of the radiation must be evaluated considering the emission limits provided by the Artificial Optical Radiation Directive (2006/25 / EC).

The results offered in a photobiological safety test report (blue light risk) depend on the type of product to be evaluated (light source or source integrated into a general lighting product):

Classification of the blue light risk group (LB, EB), according to UNE-EN 62471: 2009 and according to the technical report IEC TR 62778: 2014.

Determination of the risk group of a luminaire or other final product based on the results of the primary source.

Determination of illuminance, Ethr and distance dthr, where a product changes from class RG2 to class RG1.

Test and calculation results are always provided in our reports together with their corresponding measurement uncertainties.
