Abstract
A lamp includes a vehicle position sensing unit for sensing a position of a forward vehicle. The lamp includes a plurality of lamp units for changing beam patterns by opening or closing a portion of a shield having a plate shape, a shield actuating unit actuating the shield to open or close the portion of the shield and an optical axis adjustment unit for changing a direction of irradiation of light by adjusting an optical axis of at least one of the plurality of lamp units. In particular, a control unit forms a shadow zone by controlling at least one of the shield actuating unit and the optical axis adjustment unit according to the sensed position of the forward vehicle.
Claims18
A lamp for a vehicle, comprising:
- a vehicle position sensing unit sensing a position of a forward vehicle;
- a plurality of lamp units changing beam patterns by opening or closing a portion of a shield having a plate-shaped;
- a shield actuating unit actuating the shield to open or close the portion of the shield;
- an optical axis adjustment unit changing a direction of irradiation of light by adjusting an optical axis of at least one of the plurality of lamp units;
- and
- a control unit forming a shadow zone by controlling at least one of the shield actuating unit and the optical axis adjustment unit according to the sensed position of the forward vehicle,
- wherein the shield includes a fixed shield, fixedly installed, and a movable shield, actuated by the shield actuating unit to open or close the portion of the shield, and
- wherein the shield actuating unit rotates the movable shield toward a front of the shield.
A lamp for a vehicle, comprising:
- a plurality of light-emitting units disposed in different directions from an optical axis;
- a lens disposed at the front of the plurality of light-emitting units and transmitting light therethrough;
- and
- a shield including a fixed shield, which is fixedly installed in a predetermined area between the plurality of light-emitting units and the lens, and a movable shield, which selectively opens or closes an incised groove formed at the front of the fixed shield.
A controlling method of a lamp for a vehicle, comprising:
- forming by a controller a low beam pattern and a beam pattern for a long-range visibility with the use of a plurality of lamp units, each of the plurality of lamp units including a shield having a portion to be opened or closed;
- sensing by a controller a position of a forward vehicle;
- and
- forming by a controller a shadow zone by closing the portion of the shield or changing a direction of irradiation of light of at least one of the plurality of lamp units according to the sensed position of the forward vehicle,
- wherein the shield includes a fixed shield, fixedly installed, and a movable shield, actuated by a shield actuating unit to open or close the portion of the shield, and
- wherein the shield actuating unit rotates the movable shield toward a front of the shield.
