Abstract:
1. A two-light headlamp in which a predetermined light distribution pattern for passing by and a predetermined light distribution pattern for driving are obtained from one light source, the two-light headlamp comprising: a shade which comprises a thin plate structure, and switches the light from a light source to a low beam by which the predetermined light distribution pattern for passing by is obtained, or to a high beam by which the predetermined light distribution pattern for driving is obtained; a plate spring which moves the shade linearly in a direction perpendicular to a light axis of the light source and switches the shade to a low-beam position, where the low beam is obtained, by a spring force and holds the shade in that position; and a solenoid which switches the shade to a high-beam position, where the high beam is obtained, by a driving force when the electric supply is ON and holds the shade in that position, wherein the solenoid has a plunger driven in the direction perpendicular to the light axis of the light source.
