A headlight for motor vehicles has a reflector, a lamp support, a gas discharge lamp arranged in the reflector on the lamp support and including a region extending in the reflector and a glass cylinder which at least partially absorbs light in UV-wavelength range and surrounds the region of the gas discharge lamp, and a light stop which at least partially screens a light emitted by the gas discharge lamp. The light stop is at least indirectly mounted on the reflector, the glass cylinder is held on the light stop at least in its end region facing a light direction, the glass cylinder adjoins the lamp support, and the lamp support and the gas cylinder are arranged so that an opening leading to an interior of the glass cylinder remains between the lamp support and the glass cylinder.

Headlight for motor vehicles

The motor vehicle headlight includes a gas discharge lamp, a reflector for collecting and directing the light from the light source through an outlet opening, a light window covering the outlet opening, a disk-like filter at least partially absorbing UV radiation generated by the gas discharge lamp located between the gas discharge lamp and the light window in a path of the light transmitted directly transmitted to the light window and reflected from the reflector, at least one electrical conductor arranged on the filter so that, when the filter is broken, the electrical conductor is broken, and a control unit having a safety circuit connected directly to the electrical conductor by two lines. The safety circuit is structured and connected to the gas discharge lamp so that the gas discharge lamp is turned off by the safety circuit when the electrical conductor is broken.
