Glossary
1)
Radiant intensity:MeasuredatasolidangleofΩ=0.001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.
6)
Testing temperature: T
A
= 25°C
7)
Tolerance of Measure:Unlessotherwisenotedindrawing,tolerancesarespeci󰘰edwith±0.1and
dimensionsarespeci󰘰edinmm.
