7.2.1 Headlight beam optical center alignment
BEAM TYPE INTRODUCTION
The actual versions of headlight beams on the
market can be summarized in three main groups
from the point of view of the end user:
-
Parabola version
-
Lenticular version
LED matrix version
-
Parabola version consisting of a
back slices panel and a bulb
emitting the light projection.
Lenticular version consisting
of a frontal lens emitting the
light projection straight from
the bulb through the lens.
LED Matrix assembly version
consisting of specific single
LED assembly in a detailed
cell.
HOW TO CENTER THE BEAM
All Kraftwerk headlight testers are equipped
with laser pointing system to
ensure the correct aiming of
the center of the beam/the
bulb of the beam
Parabola version:
Optical laser pointingsystem
must be directed on the
beam bulb
Lenticular version:
Optical laser pointing system
must be directed in the
center of the lens.
LED assembly version:
Assembly beam has to be
checked, starting from low
beam position centering the
MASTER LED shape
7.3 Measurement process
Test must be performed with thelogon
engine. If you are operating indoors,
before starting the engine, start the
exhaust gas extraction system to expel the
exhaust gases outside the working environment
in accordance with the current legal provisions.
In case of vehicles with air suspension turn on the
engine five minutes before starting the test and
proceed with engine on.
CONCEPTS OF HEADLIGHT BEAM ASSEMBLY
INCLINATION = Vertical axel beam
inclination
DEVIATION = horizontal axel beam deviation
7.3.1 Ec headlight beam
ADJUSTMENT
Read at the top of the headlight case of the
vehicle and set the nominal inclination indicated
by the manufacturer, e.g. 1.2%, rotate the wheel
at the back of the optical chamber accordingly.
If there is no indication from the manufacturer,
follow local current law.
DANGER!
Remember that the adjustment of the headlights
still complies with the current law, which
stipulates that for the low beam positioned at a
working height max 80 cm related vertical
inclination must be 1%
