PrevaLED ® Core Z3 LED modules | Optical considerations
2.3 Refl ector mounting
The LED modules have a clearly defi ned optical contact
area (OCA), which provides a defi ned surface for attaching
the refl ector. In this confi guration, the mounting and mecha-
nical support of the refl ector must be ensured by the lumi-
naire body or by suitable structures for refl ector mounting.
The following has to be considered when mounting the re-
fl ector: Due to the creepage and clearance distances speci-
fi ed in the norm (IEC 61347-1/U935, among others), it is re-
commended to stay within the OCA values of the corres-
ponding category (see PrevaLED
® datasheet).
Additionally, a bayonet base option is provided, with the
help of which the refl ector can be attached directly to the
PrevaLED
® Core Z3.
Allowed compression: 20 N
Allowed tension: 20 N
Allowed torque: 1 Nm
2.4 Color temperature
The PrevaLED ® Core Z3 series is currently available in 2 700
K, 3 000 K, 3 500 K and 4 000 K. The color coordinates
within the CIE 1931 color space are given below.
Within each available color temperature, the PrevaLED ®
Core Z3 series provides a maximum color variation of three
threshold value units (MacAdam steps). The following dia-
gram shows these threshold values within the CIE 1931
color space.
