Anm.: -35 Farbselektiert nach Farbortgruppen (siehe Seite 5).
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 - Montageprozess) erlaubt
keine Zusage einer einzelnen Helligkeitsgruppe. Daher mssen mindestens zwei
Helligkeitsgruppen vorgesehen werden!
Note: -35 Color selection acc. to Chromaticity coordinate groups (see page 5)
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!

1
A critical component is a component used in a life-support device or system whose failure can reasonably be expected
to cause the failure of that life-support device or system, or to affect its safety or the effectiveness of that device or
system.
2
Life support devices or systems are intended (a) to be implanted in the human body, or (b) to support and/or maintain
and sustain human life. If they fail, it is reasonable to assume that the health of the user may be endangered.
