Xenon lamps
155n
Xenon lamps provide significantly
improved visibility, especially during
adverse weather conditions and driving
situations, e.g. driving at night in heavy
rain or through road repair areas where
there are no lane markers.
Vehicles with xenon lamps are
equipped with automatic headlamp
range control. As a result, the highway
is always optimally lighted, regardless
of load conditions, and drivers in
oncoming traffic are not blinded.
Xenon lamps illuminate the side and
front areas of the vehicle much more
brightly and with greater uniformity than
traditional halogen lamps.
Xenon lamps make a significant contri-
bution to highway safety since other
highway users, bicyclists and motorcy-
clists in the right lane, and pedestrians
are more easily detected.
In a xenon lamp, an electric arc
replaces the filament to generate
intense illumination. A gas mixture in a
quartz glass tube with metal vapor is
ignited by a high electric voltage. The
arc that is generated is then sustained
by a lower voltage. When the lamp is
turned on, there is a brief warm-up
period. Maximum brightness is attained
in approx. 15 seconds.
