Description

Lamp for vehicle

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a lamp for a vehicle, and more particularly to a lamp for a vehicle which can easily form a dark zone according to the position of a front vehicle while sufficiently securing a driver's field of view.

Generally, a vehicle has a lighting function for easily confirming an object located in the vicinity of the vehicle at nighttime driving, and a lamp having a signal function for notifying other vehicle or road users of the running state of the vehicle.

For example, head lamps and fog lamps are intended for illumination purposes, and turn signal lamps, tail lamps, brake lamps, side markers, and the like are signals.

Of these, the headlamp has an essential function of securing the front view of the driver by irradiating light in the same direction as the running direction of the vehicle when the vehicle travels in the nighttime or in a tunnel with low ambient brightness.

In recent years, there has been an increasing demand for safety in order to enable safer driving. To this end, when the vehicle is turned on at night and the headlamp is turned on, it causes glare to the driver of the preceding vehicle or the driver of the opposite vehicle, , There is a possibility that the possibility of a vehicle accident may increase. Accordingly, there is a demand for a method of ensuring the visibility of the driver of the vehicle while preventing the visibility of the driver of the preceding vehicle or the driver of the opposite vehicle from being disturbed.
