Abstract

PURPOSE:To make it possible to precisely detect a vehicle, even a bus or the like, with the use of a head light change-over device using a light sensor for detecting the approaching of a vehicle to change over the high and low beams of head lights, by making large the upward directivity angle of one of several photoelectric elements constituting a photo-sensor, which is in the vicinity of the center section of the photo-sensor. CONSTITUTION:A head light change-over device comprises a lens 10 for focusing light from the head lights of a vehicle on the opposite lane and light from the tail lights of a vehicle ahead of the instant vehicle and a light sensor 20 composed of a plurality of photo-electric elements 20a through 20g and delivering a plurality of light photoelectric signals Sn in accordance with the focused light. Further, these photoelectric signals Sn successively converted into voltages Vkn by means of an input processing circuit 30, and thereafter, is delivered through an AD converter circuit 40 into a control circuit 50 for controlling a drive circuit 60 which turns on a low beam lamp 72 or a high beam lamp 71 in each head light 70 in accordance with the output of the circuit 50. In this arrangement, the photoelectric element 20g in the photo-sensor 20 has a directivity angle which is larger than the vertical and horizontal light receiving directivity angles of the other photoelectric elements, and therefore, it is possible to detect the approaching of even a vehicle having tail lamps positioned at a high level.
