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 device specied 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 eect. 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 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 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.

Glossary
1) Radiant intensity: Measured at a solid angle of Ω = 0.01 sr
2) Reverse Operation: Reverse Operation of 10 hours is permissible in total. Continuous reverse opera-
tion is not allowed.
3) Total radiant ux: Measured with integrating sphere.
4) Thermal resistance: junction - soldering point, of the device only, mounted on an ideal heatsink (e.g.
metal block)
5) Thermal resistance: junction ‐ ambient, mounted on PC‐board (FR4), padsize 16 mm² each
6) 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 reect statistical gures.
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.
7) Testing temperature: TA = 25°C
8) Tolerance of Measure: Unless otherwise noted in drawing, tolerances are specied with ±0.1 and
dimensions are specied in mm.
9) Tape and Reel: All dimensions and tolerances are specied acc. IEC 60286-3 and specied in mm.
