Anm.: Die Standardlieferform von Serientypen beinhaltet eine untere bzw. eine obere Familiengruppe
oder mindestens zwei Einzelgruppen.
In einer Verpackungseinheit / Gurt ist immer nur eine Helligkeitsgruppe enthalten.
Die technologiebedingte Helligkeits-Streuung der heutigen LED-Herstellprozesse ber einen
lngeren Fertigungszeitraum (Halbleitermaterial - Chipherstellung - Montageprozesss) erlaubt
keine Zusage einer einzelnen Helligkeitsgruppe. Daher mssen mindestens zwei
Helligkeitsgruppen vorgesehen werden!
Dimmverhltnis im Gleichstrom-Betrieb max. 5:1
Note: The standard shipping format for serial types includes a lower or upper family group or at least
two individual groups.
No packing unit / tape ever contains more than one luminous intensity group.
Luminosity variations caused by the technology used in current LED manufacturing processes
over a protracted manufacturing period (semiconductor material - chip fabrication - assembly
process) mean that it is not possible to assign LEDs to a single luminous intensity group. For this
reason at least two luminous intensity groups must be provided!
Dimming range for direct current mode max. 5:1
