Abstract:
1. A headlamp comprising: a light source; a shade that forms a light distribution pattern for a low beam when the shade is in a low beam position and a light distribution pattern for a high beam when the shade is in a high beam position with a light from the light source; a solenoid having a plunger configured to move the shade from the low beam position to the high beam position via a magnetic force; a stopper mechanism configured to stop the shade at either of the low beam position and the high beam position; and a spring configured to move the shade from the high beam position to the low beam position via an elastic force, wherein a difference between the magnetic force and the elastic force initially increases and then decreases over the stroke of the plunger, to change a moving speed of the shade as the shade moves position.
