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 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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.

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‐ambient,mountedonPC‐board(FR4),padsize16mm²each
5) 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.
