Lamp for vehicle
Disclosed is a lamp for a vehicle including a light source unit, a first lens unit disposed on a front side of the light source unit, and that condenses a light output from the light source unit and output the light to a front side, and a second lens unit provided on a front side of the first lens unit, and that diffuses and outputs the light input from the first lens unit, and the second lens unit includes a plurality of optics provided on any one of a surface, to which the light is input, and a surface, from which the light is output, formed to extend in a first direction that is perpendicular to a ground surface, and arranged along a second direction that is perpendicular to the first direction.
1. A lamp for a vehicle, comprising:
a light source unit configured to output light;
a first lens unit disposed on a front side of the light source unit through which light from the light source unit passes, the first lens unit being configured to condense the light from the light source unit and output the light through a front side of the first lens unit; and
a second lens unit disposed on the front side of the first lens unit configured to diffuse and output the light,
wherein the second lens unit includes:
a plurality of optics through which the light passes, each of the optics extending from a top to a bottom of the second lens unit in a first direction perpendicular to a ground surface and the plurality of optics being arranged along a second direction perpendicular to the first direction,
a lens body including a second input surface that faces the first lens unit and a second output surface that faces away from the second input surface, and
the plurality of optics is disposed on the second input surface and the second output surface is flat, and
wherein the first lens unit includes:
an input part including a first input surface that is a surface through which the light is received from the light source unit; and
an output part including a first output surface through which the light input to the input part is output, and
the first output surface is configured such that the output part forms an aspheric lens, the aspherical lens having a non-planar surface that is non-spherical, and
wherein a vertical cross-sectional shape of the plurality of optics gradually changes from the lower end part to the upper end part.
2. The lamp of claim 1 , wherein the aspheric lens is focused on the first input surface.
3. The lamp of claim 1 , wherein the input part has a four-sided plate shape or a disk shape.
4. The lamp of claim 1 , further comprising:
a shield part disposed on the first input surface,
wherein the shield part is configured to shield a portion of the light to form a low beam pattern.
5. The lamp of claim 4 , wherein the shield part is coated at the first input surface with a material that shields the light.
6. The lamp of claim 4 , wherein the shield part is formed in a lower area of the first input surface.
7. The lamp of claim 1 , wherein a radius of curvature of the plurality of optics decreases from the upper end part to the lower end part.
8. The lamp of claim 1 , wherein a thickness of the plurality of optics increases from the upper end part to the lower end part.
9. The lamp of claim 1 , wherein widths of the plurality of optics in the second direction are mutually constant.
