NotesThe 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
device specified 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 effect. 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.
Subcomponents of this device contain, in addition to other
substances, metal filled materials including silver. Metal filled
materials can be affected by environments that contain traces of
aggressive substances. There-fore, we recommend that customers
minimize device exposure to aggressive substances during storage,
production, and use. Devices 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.

Glossary1) Radiant intensity: Measured at a solid angle of Ω =
0.01 sr2) Brightness: The brightness values are measured with a
tolerance of ±11%.3) Reverse Operation: This product is intended to
be operated applying a forward current within the
specified range. Applying any continuous reverse bias or forward
bias below the voltage range of light emission shall be avoided
because it may cause migration which can change the electro-optical
char-acteristics or damage the LED.
4) Forward Voltage: The forward voltages are measured with a
tolerance of ±0.1 V.5) Total radiant flux: Measured with
integrating sphere.6) Thermal resistance: junction - soldering
point, of the device only, mounted on an ideal heatsink (e.g.
metal block)7) Thermal resistance: junction ‐ ambient, mounted
on PC‐board (FR4), padsize 16 mm² each8) Typical Values: Due to the
special conditions of the manufacturing processes of semiconductor
devic-
es, the typical data or calculated correlations of technical
parameters can only reflect statistical figures. These do not
necessarily correspond to the actual parameters of each single
product, which could dif-fer from the typical data and calculated
correlations or the typical characteristic line. If requested, e.g.
because of technical improvements, these typ. data will be changed
without any further notice.
9) Testing temperature: TA = 25°C (unless otherwise
specified)10) Tolerance of Measure: Unless otherwise noted in
drawing, tolerances are specified with ±0.1 and
dimensions are specified in mm.11) Tape and Reel: All dimensions
and tolerances are specified acc. IEC 60286-3 and specified in
mm.
