Notes

The evaluation of eye safety occurs according to the standard IEC 62471:2006 (photo biological safety of

lamps and lamp systems). Within the risk grouping system of this IEC standard, the LED speci󰘰ed in this

data sheet falls into the class exempt group (exposure time 10000 s)

. Under real circumstances (for expo-

sure time, conditions of the eye pupils, observation distance), it is assumed that no endangerment to the

eye exists from these devices. As a matter of principle, however, it should be mentioned that intense light

sources have a high secondary exposure potential due to their blinding e󰘯ect. When looking at bright light

sources (e.g. headlights), temporary reduction in visual acuity and afterimages can occur, leading to irrita-

tion, annoyance, visual impairment, and even accidents, depending on the situation.
