PROTECTION
CLASS
IP
IK
Protection classes indicate
which safety measures a device
has installed to prevent electric
shocks. There are three protec-
tion classes which are repre-
sented by the symbols below.
The abbreviation IP stands for
Ingress Protection. The first digit
in these standardised IP codes
indicates the protection against
solid objects, the second digit
indicates protection against
moisture.
The IK protection class is a
classification of building materials
and surfaces that determines
how resistant they are to
mechanical impact such as
blows, collisions or pressure.
HALF-DIFFU-
SION ANGLE
UGR
SMART
LIGHTING
The half beam angle describes
the light emission taking the
composition of the luminaire,
lamp and distance from an
object into account. The smaller
the half beam angle, the narrower
the beam of light.
UGR (Unified Glare Rating) rates
the glare of a luminaire to relieve
the eye. The lower the UGR
value, the more pleasant the
light is to the eye. A UGR<19
is therefore recommended for
workplaces.
Smart Lighting describes auto-
mated light management. With
DALI, ZIGBEE, Casambi and
BLUETOOTH, smart luminaires
can be controlled via apps and
other controls.
