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 specied in this
data sheet fall into the class exempt group (exposure time 10000 s). 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 eect. As is also true when viewing other 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.
Subcomponents of this LED contain, in addition to other substances, metal lled materials including silver.
Metal lled materials can be aected by environments that contain traces of aggressive substances. There-
fore, we recommend that customers minimize LED exposure to aggressive substances during storage, pro-
duction, and use. LEDs that showed visible discoloration when tested using the described tests above did
show no performance deviations within failure limits during the stated test duration. Respective failure limits
are described in the IEC60810.
Based on very short life cycle times in chip technology this component is subject to frequent adaption to the
latest chip technology.
