Abstract

A lamp for a vehicle includes a light source part including a light source, a first lens part including a plurality of micro incidence lenses on which light generated from the light source part is incident, a second lens part including a plurality of micro emitting lenses each corresponding to each of the plurality of micro incidence lenses, and a shield part disposed between the first lens part and the second lens part. The shield part includes a plurality of shields configured to block some of the light incident from the plurality of micro incidence lenses on the plurality of micro emitting lenses. In particular, a light axis of the light source may be disposed to be spaced apart from a center line which connects centers of an incidence surface and an emitting surface of the first lens part in at least one of a side direction or a downward direction.

First claim

1 - 11 . (canceled)

12 . A lamp for a vehicle, comprising:
a light source part including a light source; a first lens part including a plurality of micro incidence lenses on which light generated from the light source part is incident; a second lens part including a plurality of micro emitting lenses each corresponding to each of the plurality of micro incidence lenses; and a shield part disposed between the first lens part and the second lens part, wherein the shield part includes a plurality of shields configured to block some of the light incident from the plurality of micro incidence lenses on the plurality of micro emitting lenses, wherein a light axis of the light source is disposed to be spaced apart from a center line which connects centers of an incidence surface and an emitting surface of the first lens part in at least one of a side direction or a downward direction.

13 . The lamp of claim 12 , wherein the center line of the first lens part is coincident with a center line which connects centers of an incidence surface and an emitting surface of the second lens part.

14 . The lamp of claim 12 , wherein light emitted from each of the plurality of micro incidence lenses is incident on at least one of the micro emitting lenses that corresponds to each of the plurality of micro incidence lenses and a micro emitting lens adjacent to the at least one corresponding micro emitting lens.

15 . The lamp of claim 14 , wherein the light incident to the adjacent micro emitting lens extends a light irradiation range of the at least one corresponding micro emitting lens in a side direction.

16 . The lamp of claim 12 , wherein:
the light source part further includes a light guide part configured to adjust a light path to allow the light generated from the light source to proceed in parallel with the light axis of the light source; and a center of the light guide part is disposed at the center line of the first lens part.

17 . The lamp of claim 16 , wherein the light guide part includes a collimator lens configured to convert the light generated from the light source to parallel light.

18 . The lamp of claim 12 , wherein some of the plurality of shields include shapes different from shapes of other shields among the plurality of shields to form different areas of the beam pattern.

19 . The lamp of claim 12 , wherein at least one of the plurality of micro incidence lenses or the plurality of micro emitting lenses is a lens having a semi-cylindrical shape that extends in one direction.
