Description of the Related Art [0002] Generally, a vehicle is equipped with various types of vehicle lamps having a lighting function for easily confirming an object located in the vicinity of the vehicle at nighttime, and 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 mainly aimed at lighting functions, while turn signal lamps, tail lamps, brake lamps, side markers and the like are mainly used for signal functions. In addition, such vehicle lamps are prescribed by laws and regulations on installation standards and specifications so that each function can be fully utilized.

Among such lamps, a headlamp which forms a low beam pattern or a high beam pattern so as to secure a front view of the driver at nighttime is playing a very important role in safety operation.

The headlamp can form a beam pattern such as a low beam pattern or a high beam pattern according to the driving environment of the vehicle, for example, the surrounding brightness, the surrounding vehicle, the road environment, the weather environment, and the like. A plurality of light source units 11 and 12 can be positioned in different directions with respect to the optical axis and light emitted from the light source 11a of any one of the plurality of light source units 11 and 12 Is reflected forward by the reflector 11b and the light reflected by the reflector 11b is incident on the lens 30 while being partially blocked by the shield 20 to form a low beam pattern as shown in Fig. .

At this time, a shielding layer 20 is formed on the shield 20 so that the shielded light can be reflected by the lens 30, and the light reflected by the lens 30 enhances the near vision of the low beam pattern.

3, the light generated from each of the light sources 11a and 11b included in the plurality of light sources 11 and 12 is reflected by the reflectors 11b and 11b, 12b so that the position of the shield 20 is changed so as not to block the light reflected by the reflectors 11b, 12b, thereby forming a high beam pattern as shown in FIG.

When a high beam pattern is formed by changing the position of the entire shield 20 as shown in FIG. 3, a structure for changing the position of the entire shield 20 is required. Therefore, As shown in FIG. 4, the unnecessary portion A is formed in the high beam pattern as shown in FIG. 4, so that a sense of heterogeneity occurs in the road surface pattern. As shown in FIG. 1, by the reflective layer of the shield 20, The near vision is reduced.

Therefore, a plurality of light source units 11, 12 are provided to form an optimal beam pattern while reducing light loss in a vehicle lamp that forms various beam patterns, and it is necessary to change the position of the shield 20 There is a need for a method for reducing the space to be used.
