Abstract

Disclosed is a lamp for a vehicle including a light source part that irradiates light, and a shutter unit provided on a front side of the light source part and that shuts at least a portion of the light, the shutter unit includes a plurality of shutter members that are moved in a direction that crosses a forward/rearward direction (F), and the plurality of shutter members are spaced apart from each other along the forward/rearward direction (F).

First claim

What is claimed is:

1. A lamp for a vehicle comprising:
a light source part configured to irradiate light; and
a shutter unit spaced apart from the light source part in a first direction and configured to block at least a portion of the light irradiated from the light source part,
wherein the shutter unit includes:
a plurality of shutter members configured to move linearly in a second direction traversing the first direction extending between the light source part and the shutter unit, and
wherein the plurality of shutter members are spaced apart from each other along the first direction.

2. The lamp of claim 1 , wherein the plurality of shutter members overlap each other in the first direction.

3. The lamp of claim 1 , wherein the second direction is perpendicular to the first direction.

4. The lamp of claim 1 , wherein:
the shutter unit further includes a unit body having a through-hole extending in the first direction, and
the plurality of shutter members are coupled to a circumferential area of the unit body which defines a border of the through-hole.

5. The lamp of claim 4 , wherein the plurality of shutter members are coupled to the unit body to be linearly movable in the second direction.

6. The lamp of claim 4 , wherein:
the circumferential area of the unit body includes an insertion section having a shape that is recessed in a direction that extends away from the through-hole, and
the plurality of shutter members are inserted into the insertion section.

7. The lamp of claim 4 , wherein the shutter member includes:
an upper shutter member coupled to an upper circumferential area formed in an upper area of the circumferential area; and
a lower shutter member coupled to a lower circumferential area formed in a lower area of the circumferential area.

8. The lamp of claim 7 , wherein:
the upper shutter member is coupled to the upper circumferential area and is linearly movable in the second direction, and
the lower shutter member is coupled to the lower circumferential area and is linearly movable in the second direction.

9. The lamp of claim 4 , wherein the plurality of shutter members includes a shutter member for a low beam, the shutter member having an upper end portion having a step-shaped cutoff area, having a step shape is formed at an upper end thereof.

10. The lamp of claim 9 , wherein the shutter member for the low beam includes a lower shutter member coupled to a lower circumferential area of the circumferential area formed in a lower area of the shutter member.

11. The lamp of claim 9 , wherein the shutter member for the low beam includes a non-light transmissive material configured to block the light irradiated from the light source part.

12. The lamp of claim 4 , wherein:
the plurality of shutter members include a shutter member for a DRL configured to transmit at least a portion of the light irradiated from the light source part to form a DRL light distribution pattern, and
the shutter member for the DRL includes an upper shutter member coupled to an upper circumferential area of the shutter member, and a lower shutter member coupled to a lower circumferential area thereof.

13. The lamp of claim 4 , wherein:
the plurality of shutter members include a shutter member for a surface irradiation pattern configured to form the surface irradiation pattern by blocking at least a portion of the light irradiated from the light source part, and
the shutter member for the surface irradiation pattern has a shape defining a through area of a shape corresponding to that of the surface irradiation pattern.

14. The lamp of claim 4 , wherein:
the plurality of shutter members include a turn-signal shutter member configured to transmit at least a portion of the light irradiated from the light source part to form a light distribution pattern for a turn signal, and
the turn-signal shutter member includes an upper shutter member coupled to an upper area of the circumferential area, and a lower shutter member coupled to a lower circumferential area thereof.

15. The lamp of claim 1 , wherein at least some of the plurality of shutter members include a micro-lens array.

16. The lamp of claim 1 , wherein at least some of the plurality of shutter members include:
a base resin defining a body of the shutter member and configured to transmit the light irradiated from the light source part; and
a diffusing agent provided in the base resin and configured to diffuse the light irradiated from the light source part.

17. The lamp of claim 1 , wherein at least some of the plurality of shutter members include:
a base body defining a body of the shutter member and configured to transmit the light irradiated from the light source part; and
a fine convexo-concave part provided on a front surface or a rear surface of the base body, and in which a pattern that diffuses the light irradiated from the light source part is formed.

18. The lamp of claim 1 , wherein at least some of the plurality of shutter members have a shape containing a plurality of fine holes formed at a body of the shutter member and arranged to (1) increase a diffusion angle of the light irradiated from the light source part, (2) output the light to a front side or diffract the light irradiated from the light source part, and (3) output the light to the front side.

19. The lamp of claim 18 , wherein sizes of some of the fine holes are different from sizes of others.

20. The lamp of claim 1 , further comprising:
a first inner lens provided between the light source part and the shutter unit, and to which the light irradiated from the light source part is input; and
a second inner lens provided on a front side of the shutter unit, and to which the light output from the shutter unit is input,
wherein a distance between the shutter unit and the second inner lens is smaller than a distance between the shutter unit and the first inner lens.
