Abstract

Provided is to a vehicle lamp capable of ensuring a high sense of unity when a plurality of lamp units are arranged based on a shape of an outer optical member. The vehicle lamp includes a light source unit for generating light, a first optical member in which a plurality of incident optics are disposed on an incident surface, a second optical member in which a plurality of emitting optics are disposed, and a shield unit disposed between the plurality of incident optics and the plurality of emitting optics. In particular, a first side of the incident surface and the emitting surface is formed to be closer to the light source unit than a second side of the incident surface and the emitting surface to allow the incident surface and the emitting surface to be inclined.

First claim

What is claimed is:

1 . A vehicle lamp, comprising:
a light source unit for generating light; a first optical member in which a plurality of incident optics are disposed on an incident surface on which light is incident from the light source unit; a second optical member in which a plurality of emitting optics are disposed on an emitting surface through which light emitted from the first optical member is incident and emitted; and a shield unit disposed between the plurality of incident optics and the plurality of emitting optics, wherein a first side of the incident surface and the emitting surface is formed to be closer to the light source unit than a second side of the incident surface and the emitting surface to allow the incident surface and the emitting surface to be inclined.

2 . A vehicle lamp, comprising:
a light source unit for generating light; a first optical member in which a plurality of incident optics are disposed on an incident surface on which light is incident from the light source unit; a second optical member in which a plurality of emitting optics are disposed on an emitting surface through which light emitted from the first optical member is incident and emitted; and a shield unit disposed between the plurality of incident optics and the plurality of emitting optics, wherein light emitted from each of the plurality of incident optics is incident on at least two of the plurality of emitting optics.

3 . The vehicle lamp of claim 1 , wherein the light source unit comprises:
a light source for generating the light; and a light guide for forming the light generated from the light source to be a parallel light.

4 . The vehicle lamp of claim 3 , wherein the light guide is formed of a Fresnel lens.

5 . The vehicle lamp of claim 1 , wherein the plurality of incident optics and the plurality of emitting optics are disposed to form a row in a horizontal direction, the row in the horizontal direction being disposed in a vertical direction, and
wherein the plurality of incident optics and the plurality of emitting optics are disposed in a stepwise manner from the first side toward the second side.

6 . The vehicle lamp of claim 1 , wherein the first optical member comprises a first light transmitting unit in which the plurality of incident optics are disposed on the incident surface, and the second optical member comprises a second light transmitting unit in which the plurality of emitting optics are disposed on the emitting surface.

7 . The vehicle lamp of claim 6 , wherein the first light transmitting unit and the second light transmitting unit are disposed to allow facing surfaces thereof to abut each other.

8 . The vehicle lamp of claim 6 , wherein the shield unit comprises a plurality of shields formed on an emitting surface of the first light transmitting unit or on an incident surface of the second light transmitting unit.

9 . The vehicle lamp of claim 8 , wherein each of the plurality of shields comprises:
an inclined edge having a lower end and an upper end; a first edge that extends from the lower end of the inclined edge; and a second edge that extends from the upper end of the inclined edge.

10 . The vehicle lamp of claim 1 , wherein light emitted from each of the plurality of incident optics is incident on at least two of the plurality of emitting optics.

11 . The vehicle lamp of claim 1 , wherein an optical axis of the incident optics and an optical axis of the emitting optics are formed to correspond to each other.

12 . The vehicle lamp of claim 1 , wherein an optical axis of the incident optics and an optical axis of the emitting optics are formed parallel to a traveling direction of the light incident on the incident surface.

13 . The vehicle lamp of claim 1 , further comprising:
at least one lamp unit including the optical unit, the first optical member, and the second optical member; and an outer optical member in which light emitted from the lamp unit is incident.

14 . The vehicle lamp of claim 13 , wherein an inclination angle and inclined direction of the incident surface and the emitting surface are determined based on a shape of the outer optical member.

15 . The vehicle lamp of claim 2 , wherein the light source unit comprises:
a light source for generating the light; and a light guide for forming the light generated from the light source to be a parallel light.

16 . The vehicle lamp of claim 2 , wherein the first optical member comprises a first light transmitting unit in which the plurality of incident optics are disposed on the incident surface, and the second optical member comprises a second light transmitting unit in which the plurality of emitting optics are disposed on the emitting surface.

17 . The vehicle lamp of claim 2 , wherein an optical axis of the incident optics and an optical axis of the emitting optics are formed to correspond to each other.

18 . The vehicle lamp of claim 2 , wherein an optical axis of the incident optics and an optical axis of the emitting optics are formed parallel to a traveling direction of the light incident on the incident surface.

19 . The vehicle lamp of claim 2 , further comprising:
at least one lamp unit including the optical unit, the first optical member, and the second optical member; and an outer optical member in which light emitted from the lamp unit is incident.
