Referring to FIG. 1, a vehicle lamp 1 according to an embodiment of the present invention includes a low beam pattern or a high beam pattern so as to ensure a forward view of a driver when the vehicle is traveling in a dark environment such as at night. And are disposed on both sides in front of the vehicle. That is, the vehicle lamp 1 according to the embodiment of the present invention means a headlamp for a vehicle.

Referring to FIG. 2, a vehicle lamp 10 according to an embodiment of the present invention includes light sources 11 and 12, a first optical member 13, and a second optical member 17.

The light source units 11 and 12 include a plurality of light sources to emit light. Each of the plurality of light sources may be a halogen lamp, an LED (Light Emitting Diode), or the like, and the generated light may be irradiated toward the front of the vehicle. At this time, the number of light sources of the light source units 11 and 12 is not limited to two as shown in FIG. 2, but may be more or less. 2, the light emitted from the first light source 11 forms a low beam pattern, and the light emitted from the second light source 12 forms a high beam pattern do.

In the first optical member 13, light emitted from the light source portions 11 and 12 is incident, and parallel light is emitted. Specifically, in the first optical member 13, light emitted from the light source portions 11 and 12 is incident on the incident portion 14, and refracted by the exit portions 15 and 16 to emit parallel light. In this case, the parallel light means light parallel to the ground.

3 is a perspective view of a first lens which is an embodiment of a lamp for a vehicle according to an embodiment of the present invention.

Referring to Fig. 3, the first optical member 13 represents a lens having a plurality of curvatures. Specifically, the first optical member 13 may mean a Fresnel lens. Therefore, the light emitted from the light source portions 11 and 12 is incident on the first optical member 13, and parallel light is emitted.

In the second optical member 17, the parallel light emitted from the first optical member 13 is refracted and irradiated forward of the vehicle. Specifically, in the second optical member 17, the parallel light emitted from the first optical member 13 is incident on the incident portion 18, refracted and emitted from the exit portions 19 and 20, And is irradiated forward of the vehicle.

4 is a perspective view of a second lens which is an embodiment of a lamp for a vehicle according to an embodiment of the present invention.

Referring to FIG. 4, the second optical member 17 includes a plurality of facets having independent curvatures at the exit portions 19, 20. Thus, the plurality of facets may all have different sizes and curvatures, and the plurality of facets may be composed of a plurality of groups of similar size or curvature. At this time, the plurality of facets are formed such that the parallel light incident on the incident portion 18 of the second optical member 17 is refracted to form a predetermined beam pattern. At this time, the predetermined beam pattern includes a low beam pattern and a high beam pattern.

Specifically, the emitting units 19 and 20 are arranged in a lattice form. Therefore, the plurality of facets are formed to have the same interval in the transverse direction. However, the plurality of facets are formed in a stepped shape in the longitudinal direction as shown in Fig. 4, unlike a general lattice form. Accordingly, a part of the light transmitted through the plurality of facets is downward, and a part of the light is upward, thereby forming a low beam pattern or a high beam pattern.

The emitting portions 19 and 20 include a first region 19 formed to form the low beam pattern and a second region 20 formed to form the high beam pattern. In particular, most of the facets included in the first region 19 are formed in an upward tilted form relative to the ground so that light is emitted downward for the formation of the low beam pattern. At this time, the first region 19 may be formed in at least one of the high illuminance region, the intermediate diffused region, and the large diffused region among the low beam patterns according to the portion where the parallel light incident on the incident portion of the second optical member 17 is refracted and emitted And may be formed to form one region.

On the other hand, most of the facets included in the second region 20 are formed to be inclined downward with respect to the ground so that light is emitted upward to form the high beam pattern.

At this time, depending on which part of the first region 19 the parallel light is emitted, the low beam pattern formed by the parallel light is changed as described above. That is, the parallel light forms a specific region of the high-illuminance region, the intermediate diffusion region, or the large diffusion region among the low beam patterns depending on the portion to be emitted.

6 is a view showing a light path for forming a high beam pattern in a vehicle lamp according to an embodiment of the present invention.

6, the light emitted from the first light source 11 is emitted as parallel light through the first optical member 13, and the parallel light emitted from the first optical member 13 passes through the second optical member 17 and then emitted to the second region 20 of the second optical member 17 to form the high beam pattern.

At this time, the light emitted from the second region 20 of FIG. 6 is emitted upward with respect to the ground. For example, light emitted from the second region 20 may be emitted with an upward angle of 0.1 DEG with respect to the ground. This is because the position where the light emitted from the on-vehicle lamp 10 forms the high beam pattern is approximately 25 m in front of the vehicle. That is, when the light emitted from the second region 20 is emitted upward from the point where the light is emitted, the light emitted from the vehicle lamp 10 can not properly form the high beam pattern, The light emitted from the light source is emitted upward with respect to the ground.
