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 - soldering point, of the device only, mounted on an ideal heatsink (e.g.
metal block)
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.
8)
Tape and Reel: All dimensions and tolerances are speci󰘰ed acc. IEC 60286-3 and speci󰘰ed in mm.
