Wegen der Streichung der LED aus der IEC 60825-1 (2nd edition 2007-03) erfolgt die Bewertung der Augesicherheit

nach dem Standard CIE S009/E:2002 ("photobiological safety of lamps and lamp systems") / IEC 62471 (1st edition

2006-07).

Im Risikogruppensystem dieser CIE- Norm erf¸llen die in diesem Datenblatt angegebenen LED die "moderate risk"-

Gruppe (die die sich im "sichtbaren" Spektralbereich auf eine Expositionsdauer von 0,25 s bezieht). Unter realen

Umst‰nden (f¸r Expositionsdauer, Augenpupille, Betrachtungsabstand) geht damit von diesen Bauelementen keinerlei

Augengef‰hrdung aus.

Grunds‰tzlich sollte jedoch erw‰hnt werden, dass intensive Lichtquellen durch ihre Blendwirkung ein hohes se-

kund‰res Gefahrenpotenzial besitzen. Wie nach dem Blick in andere helle Lichtquellen (z.B. Autoscheinwerfer) auch,

kˆnnen tempor‰r eingeschr‰nktes Sehvermˆgen und Nachbilder je nach Situation zu Irritationen, Bel‰stigungen, Be-

eintr‰chtigungen oder sogar Unf‰llen f¸hren.

Due to the cancellation of the LED from IEC 608251 (2nd edition 2007-03) , the evaluation of eye safety occurs accor-

ding to the dual IEC/CIE logo standard CIE S009/E:2002 ("photobiological safety of lamps and lamp systems")-

IEC 62471 (1st edition 2006-07).

Within the risk grouping system of this CIE standard, the LEDs specified in this data sheet fall into the "lmoderate risk"

group (relating to devices in the visible spectrum with an exposure time of 0.25s). Under real circumstances (for expo-

sure time, 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 effect. As is also true when viewing other bright light sources (e.g. headlights), temporary

reduction in visual acuity and afterimages can occur, leading to irritation, annoyance, visual impairment, and even

accidents, depending on the situation.
