3.6 Information on optical radiation
Due to the withdrawal of the LED from IEC 60825, the assessment of eye safety is done
according to CIE S009/E:2002
“Photo Biological Safety of Lamps and Lamp Systems”.
Within the risk assessment system of CIE S009/E:2002 (DIN EN 62471) the LEDs used in the
Corona II illumination unit are depending on the LED color, the focus and the intensity might
be in this risk classes:
LED
Dark Field
A

It is assumed that these devices for Class 1 do not normally present a hazard.
These classes are at full power operation; at lower current rates, the safety class for white,
red, green, blue and IR might be lower.
