Glossary
1) Brightness: Brightness values are measured during a current pulse of typically 25 ms, with an internal
reproducibility of ±8 % and an expanded uncertainty of ±11 % (acc. to GUM with a coverage factor of
k = 3).
2) Operating Conditions: Operating conditions according DC-derating (Max. Permissible Forward Current)
3) Operating Conditions: Operating conditions according Pulse-derating (Permissible Pulse Handling
Capability)
4) Reverse Operation: Reverse Operation of 10 hours is permissible in total. Continuous reverse opera-
tion is not allowed.
5) Chromaticity coordinate groups: Chromaticity coordinates are measured during a current pulse of
typically 25 ms, with an internal reproducibility of ±0.005 and an expanded uncertainty of ±0.01 (acc. to
GUM with a coverage factor of k = 3).
6) Forward Voltage: The forward voltage is measured during a current pulse of typically 8 ms, with an
internal reproducibility of ±0.05 V and an expanded uncertainty of ±0.1 V (acc. to GUM with a coverage
factor of k = 3).
7) Color reproduction index: Color reproduction index values (CRI-RA) are measured during a current
pulse of typically 25 ms, with an internal reproducibility of ±2 and an expanded uncertainty of ±3 (acc.
to GUM with a coverage factor of k = 3).
8) Thermal Resistance: The typical R value is the average of a distribution. The value was determined on
a sample basis and is not monitored.
9) Typical Values: Due to the special conditions of the manufacturing processes of LED, the typical data
or calculated correlations of technical parameters can only reect statistical gures. These do not nec-
essarily correspond to the actual parameters of each single product, which could dier 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.
10) Characteristic curve: In the range where the line of the graph is broken, you must expect higher dier-
ences between single LEDs within one packing unit.
11) Tolerance of Measure: Unless otherwise noted in drawing, tolerances are specied with ±0.1 and
dimensions are specied in mm.
12) Tape and Reel: All dimensions and tolerances are specied acc. IEC 60286-3 and specied in mm.
