Design
Bi-Xenon headlight system
Bi-Xenon, a headlight system with moveable reflector, is based on gas discharge technology. The system combines high and low beam into the same
lamp.
Due to legal requirements (regarding low beam) for this type of lamp, the vehicle must be equipped with automatic headlamp levelling.
Xenon vs. Halogen
Xenon:
-
higher color temperature, which produces a whiter light
-
better reflection of road signs and road markings
-
lower power consumption (approx. 65% lower).
Good to know:
-
Daylight has a color temperature of about 5000 °K. The closer to natural light, the less strain on the eyes. Standard H4 bulb: 3200 °K. Volvo's gas
discharge bulb: about 4200 °K.
-
With the Bi-Xenon system, high and low beam generates the same light color. The human eye thus has an easier time adjusting to switches
between high and low beam.
Bi-Xenon lamp
The light source consists of a discharge tube surrounded by a glass that filters out harmful UV radiation.
-
The discharge tube is filled with a blend of chemical compounds, including the inert gas Xenon.
-
An electric arch is created through an electrical discharge between two tungsten electrodes.
-
Because the lamp does not have a filament, it is less sensitive to bumps and vibrations.
-
Bulb designation: D1S.
-
Power consumption: 35 W.
Caution! The Bi-Xenon bulb contains mercury (less than 0.5 mg), thus classifying it as hazardous waste. Hazardous waste must be handled in
accordance with national legislation. See also Volvo Car Corporation's "Waste Management Guidelines for Dealers."
