Only one group in one packing unit (variation lower 2:1).
E7800: An aperture is used in front of the component for measurement of the radiant intensity and the half angle (diameter of
the aperture: 1.1 mm; distance of aperture to case back side: 4.0 mm). This ensures that solely the radiation in axial direction
emittingdirectlyfromthechipsurfacewillbeevaluatedduringmeasurementoftheradiantintensity.Radiationre󰘱ectedby
thebottomplate(strayradiation)willnotbeevaluated.Thesere󰘱ectionsimpairtheprojectionofthechipsurfacebyadditional
optics(e.g.long-rangelightre󰘱ectionswitches).Inrespectoftheapplicationofthecomponent,thesere󰘱ectionsaregenerally
suppressed by apertures as well. This measuring procedure corresponding with the application provides more useful values.
This aperture measurement is denoted by “E 7800” added to the type designation.

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.

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) 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.
