Abstract
To prevent scattering of projected light due to fog, the headlight is so constructed that at least that portion of the light projected in the distance (that is, not immediately in front of the vehicle and spread laterally) is polarized; thus, arrangements to prevent limitation of projected light to the region just above the path-way of the vehicle can be avoided.
Claims9
Vehicular fog headlight comprising a reflector (10) and a light source (11) located at least approximately at the focal point of the reflector to project light ahead of the vehicle and providing a distance beam directed to illuminate the region substantially in advance of the vehicle;
- wherein means are provided to direct light emanating from the lower half of the reflector immediately ahead of the vehicle;
- the distance beam is derived from the upper half of the reflector;
- and polarization means are provided polarizing at least the part of the light projected from the upper half and forming said distance beam.
