Notes
The evaluation of eye safety occurs according to the standard IEC 62471:2006 (photo biological safety of
lampsandlampsystems).WithintheriskgroupingsystemofthisIECstandard,thedevicespeciedinthis
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
sourceshaveahighsecondaryexposurepotentialduetotheirblindingeect.Whenlookingatbrightlight
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.
Subcomponentsofthisdevicecontain,inadditiontoothersubstances,metallledmaterialsincludingsilver.
Metallledmaterialscanbeaectedbyenvironmentsthatcontaintracesofaggressivesubstances.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:MeasuredatasolidangleofΩ=0.001sr
2) Reverse Operation: Reverse Operation of 10 hours is permissible in total. Continuous reverse opera-
tion is not allowed.
3) Dimensions of active chip area: The active chip area consists of 10 single chips with 1 x 1 mm each.
4) Totalradiantux: Measured with integrating sphere.
5) Thermal resistance:junction‐ambient,mountedonPC‐board(FR4),padsize16mm²each
6) Typical Values: Due to the special conditions of the manufacturing processes of semiconductor devic-
es,thetypicaldataorcalculatedcorrelationsoftechnicalparameterscanonlyreectstatisticalgures.
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.
