Abstract

The 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 the 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 micro incidence lenses on the micro emitting lenses. In particular, a center line of the second lens part is disposed to be spaced apart from a center line of the first lens part in at least one of a side direction or a downward direction.

First claim

What is claimed is:

1. 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 and to form a predetermined beam pattern,
wherein a center line which connects centers of an incidence surface and an emitting surface of the second lens part 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 a side direction and a downward direction to prevent a central region of the light emitted from the first lens part from being blocked by the shield part, and
wherein a center line of the shield part is spaced apart from the center line of the first lens part.

2. The lamp of claim 1 , wherein a micro emitting lens disposed at a center portion of the second lens part among the plurality of micro emitting lenses is disposed to be spaced apart from the center line of the first lens part in the side direction and the downward direction at a predetermined interval.

3. The lamp of claim 1 , wherein a center line of each of the plurality of micro emitting lenses is spaced apart from a center line of corresponding micro incidence lens among the plurality of micro incidence lenses by an interval that varies based on at least one of a distance or a direction from a center portion of the second lens part.

4. The lamp of claim 3 , wherein a micro emitting lens disposed to be spaced upward from the center portion of the second lens part among the plurality of micro emitting lenses is spaced apart by an interval smaller than a predetermined interval in the downward direction as the distance from the center portion of the second lens part increases.

5. The lamp of claim 3 , wherein a micro emitting lens disposed to be spaced downward from the center portion of the second lens part among the plurality of micro emitting lenses is spaced apart by an interval greater than a predetermined interval in the downward direction as the distance from the center portion of the second lens part increases.

6. The lamp of claim 3 , wherein, in a micro emitting lens disposed to be spaced apart from the center portion of the second lens part in a side direction among the plurality of micro emitting lenses, a distance spaced apart in the side direction becomes smaller than a predetermined interval as the distance from the center portion of the second lens part increases toward one side, and the distance spaced apart in the side direction becomes greater than the predetermined interval as the distance from the center portion of the second lens part increases toward the other side.

7. The lamp of claim 1 , wherein each of the plurality of shields is displaced in at least one of the side direction or the downward direction with respect to the center line of the first lens part.

8. The lamp of claim 1 , wherein some of the plurality of shields include shapes different from shapes of other shields to form different areas of the beam pattern.

9. The lamp of claim 1 , wherein the light source part further includes a light guide part configured to guide the light generated from the light source to the first lens part, and wherein the light guide part adjusts a light path to allow the light generated from the light source to proceed in parallel with a light axis of the light source.

10. The lamp of claim 9 , wherein the light guide part includes a collimator lens configured to convert the light generated from the light source to parallel light.

11. The lamp of claim 1 , wherein at least one of the plurality of micro incidence lenses or the plurality of micro emitting lenses is a lens of a semi-cylindrical shape which extends in one direction.

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 center line of each of the plurality of micro emitting lenses is spaced apart from a center line of corresponding micro incidence lens among the plurality of micro incidence lenses in a side direction, a downward direction, or both by an interval that varies based on at least one of a distance or a direction from a center portion of the second lens part.
