Lighting and/or signalling device and motor vehicle including such a device

摘要

The device e.g. front projector (1), has including a transparent element (8) for sealing a case (2), partially. A light source (3) is placed in an internal volume (Vi) defined by the case and the transparent element. An ionization device (12) emits starter particles e.g. positive and/or negative ions (13), and silver iodide particles, in the volume, where the particles are adapted to be associated with dust particles and/or water particles in suspension in the volume. The ionization device is arranged in a rear portion of the case.
