Abstract

A vehicle lamp includes a light source unit; an incident lens unit that comprises a plurality of incident lenses on which light is incident from the light source unit; an exit lens unit that comprises a plurality of exit lenses outputting the light incident from the incident lens unit; and a shield unit that obstruct a part of the light travelling toward each of the exit lenses. The shield unit comprises a plurality of shields that obstruct a part of the light travelling toward each of the exit lenses, and an upper end of each of the shields comprises a horizontal part that extends horizontally from the center of the upper end toward a shield adjacent thereto, and a connection part that extends from the horizontal part toward the adjacent shield at an angle different from the horizontal part.

First claim

What is claimed is:

1 . A vehicle lamp comprising:
a light source unit; an incident lens unit that comprises a plurality of incident lenses on which light is incident from the light source unit; an exit lens unit that comprises a plurality of exit lenses outputting the light incident from the incident lens unit; and a shield unit that obstructs a part of the light travelling toward each of the plurality of exit lenses, wherein the shield unit comprises a plurality of shields that obstruct a part of the light travelling toward each of the plurality of exit lenses, and wherein an upper end of each of the plurality of shields comprises:
a horizontal part that extends horizontally from a center of the upper end toward an adjacent shield in left and right directions and
a connection part that extends from the horizontal part toward the adjacent shield at an angle different from the horizontal part.

2 . The vehicle lamp of claim 1 , wherein the light source unit comprises:
a light source; and a light path adjustment unit that adjusts a path of the light to cause the light generated from the light source unit to travel substantially parallel to an optical axis of the light source.

3 . The vehicle lamp of claim 2 , wherein the light path adjustment unit comprises at least one of an aspheric lens or a Fresnel lens.

4 . The vehicle lamp of claim 1 , wherein each of the plurality of shields is formed such that a line connecting both ends of the horizontal part in the left and right directions and a line connecting both ends of the connection part form an obtuse angle.

5 . The vehicle lamp of claim 1 , wherein the plurality of shields are formed such that connection parts of adjacent shields are connected to each other without forming a step.

6 . The vehicle lamp of claim 5 , wherein in each of the plurality of shields, a first end of the connection part that is closer to the adjacent shield is disposed higher or lower than a second end of the connection part that is connected to the horizontal part.

7 . The vehicle lamp of claim 6 , wherein the connection part is shaped as a straight line, a curve, or a combination thereof.

8 . The vehicle lamp of claim 1 , wherein the plurality of incident lenses and the plurality of exit lenses are disposed such that one or more rows extending in the left and right directions are arranged in up and down directions, and
wherein a direction in which the connection part is determined in accordance with an angle of the rows extending in the left and right directions to a horizontal direction.

9 . The vehicle lamp of claim 1 , wherein at least some of the plurality of shields include a protrusion that protrudes upward on the upper end thereof.

10 . The vehicle lamp of claim 1 , wherein the shield unit further comprises a plurality of additional shields respectively disposed in front of the plurality of shields along a traveling direction of the light.

11 . The vehicle lamp of claim 10 , wherein the plurality of incident lenses and the plurality of exit lenses are disposed such that one or more rows extending in the left and right directions are arranged in up and down directions, and
wherein when the rows extending in the left and right directions are inclined at a predetermined angle with respect to a horizontal direction, upper and/or lower sides of additional shields adjacent to each other in the left and right directions have different positions in the up and down directions.
