ABSTRACT:
A headlight illumination field regulating apparatus includes an electromagnetic radiation emitter, a reflected radiation sensor, a comparing element, and a unit for adjusting the alignment position of the headlights. The electromagnetic radiation emitter operates to radiate two electromagnetic radiation beams on the road to the front of the automobile and the reflected radiation sensor senses reflected radiation and determines a relationship of a sensed characteristic of the first radiation beam and a sensed characteristic of the second radiation beam and creates a data point representative of the irradiated spot. The comparing element thereafter compares the determined relationship between the sensed reflected radiation characteristics with a predetermined desired position and subsequently generate a correction signal to control the regulation or adjustment of the headlights into a proper light projecting orientation which ensures a proper projection limit of the beam of the headlight.
