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 fall 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.
SubcomponentsofthisLEDcontain,inadditiontoothersubstances,metal󰘰lledmaterialsincludingsilver.
Metal󰘰lledmaterialscanbea󰘯ected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.

Glossary
1) Brightness: Brightness values are measured during a current pulse of typically 25 ms, with an internal
reproducibility of ±8 % and an expanded uncertainty of ±11 % (acc. to GUM with a coverage factor of
k = 3).
2) Reverse Operation: Reverse Operation of 10 hours is permissible in total. Continuous reverse opera-
tion is not allowed.
3) Wavelength: The wavelength is measured at a current pulse of typically 25 ms, with an internal repro-
ducibility of ±0.5 nm and an expanded uncertainty of ±1 nm (acc. to GUM with a coverage factor of k =
3).
4) Forward Voltage: The forward voltage is measured during a current pulse of typically 8 ms, with an
internal reproducibility of ±0.05 V and an expanded uncertainty of ±0.1 V (acc. to GUM with a coverage
factor of k = 3).
5) Thermal Resistance: Rth max is based on statistic values (6
σ
).
6) Thermal Resistance: RthJA results from mounting on PC board FR 4 (pad size 16 mm² per pad)
7) Typical Values: Due to the special conditions of the manufacturing processes of LED, the typical data
orcalculatedcorrelationsoftechnicalparameterscanonlyre󰘱ectstatistical󰘰gures.Thesedonotnec-
essarilycorrespondtotheactualparametersofeachsingleproduct,whichcoulddi󰘯er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.
8) Characteristic curve:Intherangewherethelineofthegraphisbroken,youmustexpecthigherdi󰘯er-
ences between single LEDs within one packing unit.
9) Tolerance of Measure:Unlessotherwisenotedindrawing,tolerancesarespeci󰘰edwith±0.1and
dimensionsarespeci󰘰edinmm.
10) Tape and Reel:Alldimensionsandtolerancesarespeci󰘰edacc.IEC60286-3andspeci󰘰edinmm.
