Motor vehicle headlight having reduced UV radiation emission

摘要

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.
