Abstract
An automobile headlight comprising a light source, a reflector having a by-passing reflecting portion, which reflects light emitted from the light source downward to form a light distribution pattern for by-passing, and a traveling reflecting portion, which reflects light emitted from the light source to a horizontal front of the automobile headlight when the movable shade is in a position for traveling straight ahead, a fixed shade which directs light emitted from the light source towards the reflector, a movable shade capable of taking a position P or Q depending on whether the automobile is traveling straight ahead or by-passing another vehicle, and a driving unit connected to the movable shade for changing a position of the movable shade, wherein when the movable shade is in the by-passing position Q, the movable shade suppresses light emitted from the light source towards the traveling reflecting portion and passes light emitted from the light source toward the by-passing reflecting portion, and when the movable shade is in the position P for traveling straight ahead, the movable shade suppresses partly emitted light at an upper end of the by-passing reflecting portion and passes light emitted from the light source toward the traveling reflecting portion and the remaining by-passing reflecting portion. The automobile headlight provides more appropriate light distribution patterns for both traveling straight ahead and by-passing another vehicle, especially for traveling straight ahead. The automobile headlight may further comprise a passing switch for enabling a passing function.
