ABSTRACT:
An infrared light unit for a motor vehicle includes a light source, a reflector having two focal regions and a lens. The light source is in one of the focal regions and produces a pool of reflected light in the other focal region, and the lens converts this pool of light into a beam projected on the road. The light unit includes, between the reflector and the lens, a filter which is opaque to visible light and transparent to infrared light, and which is movable between a position out of the path of light going from the reflector to the lens, and an active position in which all or most of the light going from the reflector to the lens passes through the filter.
