Abstract
A vehicle lamp includes a projection lens, and a light source disposed behind the projection lens. The vehicle lamp is configured to form a required light distribution pattern by irradiating light emitted from the light source forward through the projection lens. A movable lens configured to be movable in a required direction intersecting with an optical axis of the projection lens is disposed between the projection lens and the light source. A maximum luminous intensity position of the light distribution pattern is changed by moving the movable lens in the required direction.

A vehicle lamp comprising:
- a projection lens;
- and
- a light source disposed behind the projection lens,
- wherein the vehicle lamp is configured to form a required light distribution pattern by irradiating light emitted from the light source forward through the projection lens,
- wherein a movable lens configured to be movable in a required direction intersecting with an optical axis of the projection lens is disposed between the projection lens and the light source, and
- wherein a maximum luminous intensity position of the light distribution pattern is changed by moving the movable lens in the required direction,
- wherein a spot-like light distribution pattern is formed as the required light distribution pattern,
- wherein the light distribution pattern has:
- a first light distribution pattern formed when the movable lens is in a retracted position in which the movable lens is retracted from the optical axis;
- and
- a second light distribution pattern when the movable lens is in a light control position in which the movable lens is on the optical axis,
- wherein the first light distribution pattern is a light distribution pattern formed around a vanishing point in the front direction of the lamp, wherein the vanishing point is a center point of the front direction of the lamp, and
- wherein the second light distribution pattern is a light distribution pattern obtained by displacing the first light distribution pattern.
A vehicle lamp comprising:
- a projection lens;
- and
- a light source disposed behind the projection lens,
- wherein the vehicle lamp is configured to form a first light distribution pattern by irradiating light emitted from the light source forward through the projection lens,
- wherein a first light control unit configured to be able to shield a part of light which is emitted from the light source and which is directed to the projection lens is disposed between the projection lens and the light source,
- wherein a second light distribution pattern having a lateral width smaller than a lateral width of the first light distribution pattern is formed by a light-shielding action of the first light control unit, and
- wherein the vehicle lamp comprises a second light control unit configured to displace a formation position of the second light distribution pattern downward when a light-shielding by the first light control unit is performed.
