Description

Lamp for vehicle {lamp for vehicle}

The present invention relates to a vehicle lamp, and more specifically, to a vehicle lamp that forms an efficient beam pattern through one lens unit.

In general, vehicles are provided with various types of lamps having a lighting function for easily identifying an object located around the vehicle during night driving and a signal function for notifying other vehicles or road users of the driving state of the vehicle.

For example, head lamps and fog lamps mainly for lighting functions, and turn signal lamps, tail lamps, and brake lamps for signal functions. (Brake lamp), side marker, etc., and these vehicle lamps are regulated by law for their installation standards and specifications so that each function can be sufficiently exerted.

The headlamps mainly maintain a low beam pattern in normal times to prevent glare to the driver of the oncoming vehicle or the driver of the preceding vehicle traveling in the opposite direction, and when driving at high speed or in a dark environment, the headlamp is turned on as needed. A high beam pattern is formed to promote safe driving.

Among vehicle lamps, headlamps that form a low beam pattern or a high beam pattern so that a driver's forward vision is secured during night driving play a very important role in safe driving.

In addition, the tail lamp is a rear lamp mounted at the rear of the vehicle, and may include a tail-brake lamp, a turn signal lamp, a back up lamp, and the like.

Among these, the tail-brake lamp functions as a tail light that informs the rear vehicle of the position of the host vehicle during night driving and a stop light that indicates that the host vehicle is decelerating to the rear vehicle. will perform

In addition, the turn signal lamp flickers when the driver manipulates the direction indicating lever to change the direction of the course on which the subject vehicle wants to drive, thereby performing a function of allowing the rear vehicle to recognize the change in the driving direction.

In addition, when the shift stage is set to reverse for reverse, the backup lamp functions as a reverse light indicating that the vehicle is moving backward as it is turned on.

However, since such a conventional vehicle lamp uses a plurality of lens modules to form a beam pattern, since it uses many light sources and many optical elements, a large amount of power is consumed and the size occupied by the vehicle lamp in the vehicle is inevitably increased.
