XENON HEADLAMPS, FUNCTION - GF82.10-P-2007-01GHA
The lighting technology, known as bi-xenon 70 , is located in the outer headlamps.
When the low beam lamps are switched on the xenon headlamp control module (E1 n1, E2n1) activates the
xenon headlamp control module and ignition module (E1n2, E2n2) via the control voltage within a few
milliseconds.
A high-voltage surge from the ignition device ignites the xenon lamps, and in doing so an electric arc is formed
between the electrodes. When an arc of sufficient stability is detected, the control electronics of the control
module (E1 n1, E2n1) switches over to power-limiting mode.
The light generated previously in a gas discharge lamp (D2S lamp) is not reflected in bi-xenon 70 headlamps,
but instead it is sent directly through a lens optical system with a lens diameter of 70 mm.
Using the mask (B), which is positioned between the gas discharge lamp and the lens optical system, the beam
of light is partially masked for the low beam so that oncoming traffic is not blinded.
For the high beam, the mask (B) is electro-mechanically folded to the side using the solenoid (M).
If the solenoid (M) should fail or a supply line breaks, the mask (B) remains mechanically held in the low
beam position, always between the gas discharge lamp and the lens optical system.
In order to make the extremely bright light more acceptable to other road users, the lens aperture area with its
dotted characteristic is optically enlarged.
This is possible on account of the specially formed areas which surround the lens. In addition, the light can pass
through a number of chrome-plated strips from the rear. A portion of the diffused light is intercepted by the
lower section of the surface area and reflected to the upper section of the chrome-plated longitudinal strips.

For technical reasons the xenon lamp has a timed startup characteristic. After switch on, 50 % of the luminosity
is reached within 1 to 2 seconds and full luminosity is achieved after another approx. 30 seconds.
