Abstract

A vehicle lamp is capable of forming a predetermined beam pattern with at least one lamp module. The at least one lamp module includes a light source unit, which includes at least one light source, and an optical unit, which transmits at least some of light emitted from the light source unit to form the beam pattern. The optical unit includes an incident part, which includes a plurality of incident lenses, and an exit part, which includes a plurality of exit lenses respectively corresponding to the plurality of incident lenses. The plurality of exit lenses are formed with a vertical length greater than a horizontal length.

First claim

What is claimed is:

1 . A vehicle lamp for forming a predetermined beam pattern comprising at least one lamp module, wherein the at least one lamp module comprises:
a light source unit, which comprises at least one light source; and an optical unit that transmits at least some of light emitted from the light source unit to form the beam pattern, wherein the optical unit comprises: an incident part, which includes a plurality of incident lenses; an exit part, which includes a plurality of exit lenses respectively corresponding to the plurality of incident lenses; and a plurality of shields for obstructing at least some of light from traveling toward the plurality of corresponding exit lenses, wherein the plurality of shields are disposed on a plane where a focus is formed between the plurality of incident lenses and the plurality of corresponding exit lenses, wherein a focal length of the plurality of incident lens is formed to be longer than a focal length of the plurality of corresponding exit lenses with respect to the focus, and wherein the plurality of exit lenses are formed with a vertical length thereof greater than a horizontal length thereof.

2 . The vehicle lamp of claim 1 , wherein the optical unit is inclined in at least one direction such that a first side is disposed more forward than a second side.

3 . The vehicle lamp of claim 1 , wherein each of the plurality of incident lenses corresponds to two or more of the plurality of exit lenses that are disposed laterally adjacent to one another, and
wherein each of the two or more exit lenses is formed to be longer in a vertical direction than in a lateral direction.

4 . The vehicle lamp of claim 1 , wherein the plurality of incident lenses correspond one-to-one with the plurality of exit lenses, and
wherein the plurality of incident lenses and the plurality of corresponding exit lenses are formed to be longer in a vertical direction than in a lateral direction.

5 . The vehicle lamp of claim 1 , wherein the plurality of shields comprise:
first sides that face the plurality of incident lenses; and second sides that face the plurality of exit lenses, wherein a reflectivity of the second sides is different from a reflectivity of the first sides.

6 . The vehicle lamp of claim 5 , wherein the reflectivity of the second sides is greater than the reflectivity of the first sides.

7 . The vehicle lamp of claim 1 , further comprising:
a light path adjustment unit that adjusts the light emitted from the light source unit into a collimated light beam to proceed to the optical unit.

8 . The vehicle lamp of claim 1 , wherein an aspect ratio of the horizontal length to the vertical length is between about 1:1.2 and about 1:2.0.
