Title:
VEHICULAR HEADLIGHT
Document Type and Number:
Japanese Patent JP3949255
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an inexpensive structure for leveling and beam switching for a vehicular headlight having a leveling device and a mechanically driven beam switching device.
SOLUTION: The structure using an actuator 26 of a leveling device 24 enables a beam switching device 32 to switch beams between a high beam and a low beam. Namely, leveling is carried out by tilting a reflector 20 which emits a light distribution pattern for the low beam two degrees upward and three degrees downward from the leveling basic angle, while switching from the low beam to the high beam is performed by tilting the reflector 20 three degrees upward from the leveling basic angle. A part of the reflector 20 consists of a subreflector 34 relatively rotating two degrees upward to the reflector 20. In the high beam, a light distribution pattern with a sufficient upward illuminating light with a fuzzy shading borderline is provided.
