Abstract

A lamp for a vehicle includes a first beam pattern formation part configured to emit first light for a first beam pattern and a lens configured to form the first beam pattern by transmitting the first light. The first beam pattern formation part includes a first light source that emits the first light; and a shield configured to block a portion of the first light that is emitted from the first light source toward the lens. The lens includes a spread lens that concentrates incident light to a focal line having a linear shape and a spot lens that concentrates incident light to a point.

First claim

What is claimed is:

1. A lamp for a vehicle, comprising:
a first beam pattern formation part configured to emit first light for a first beam pattern; and
a lens configured to form the first beam pattern by transmitting the first light,
wherein the first beam pattern formation part comprises:
a first light source that emits the first light; and
a shield configured to block a portion of the first light that is emitted from the first light source toward the lens, and

wherein the lens comprises:
a spread lens that concentrates incident light to a focal line having a linear shape; and
a spot lens that concentrates incident light to a point,

wherein the first beam pattern comprises:
a spread pattern; and
a spot pattern, which is smaller than the spread pattern and overlaps the spread pattern,

wherein the shield comprises:
a spot shield that blocks a portion of light to form the spot pattern; and
a spread shield that blocks a portion of light to form the spread pattern,
wherein the light that passes through the spread lens forms the spread pattern, and the light that passes through the spot lens forms the spot pattern,

wherein the spot shield comprises:
a boundary shield that blocks a portion of the light to form an upper boundary line of the spot pattern; and
a slope shield that blocks a portion of the light to form the upper boundary line and a slope line of the spot pattern,

wherein the lamp further comprises a first vehicle lamp disposed at a left side of the vehicle and a second vehicle lamp disposed at a right side of the vehicle,
wherein the first vehicle lamp comprises a first slope shield and a first boundary shield, and the second vehicle lamp comprises a second slope shield and a second boundary shield,
when the first slope shield is disposed more inward to the vehicle's longitudinal centerline than the first boundary shield, the second slope shield is disposed more outward from the vehicle's longitudinal centerline than the second boundary shield, and
when the first slope shield is disposed more outward from the vehicle's longitudinal centerline than the first boundary shield, the second slope shield is disposed more inward to the vehicle's longitudinal centerline than the second boundary shield.

2. The lamp of claim 1 , wherein the spread lens has an elongated shape in one direction, and
wherein the spot lens is disposed at each of both sides of the spread lens.

3. The lamp of claim 2 , wherein the first beam pattern formation part comprises a plurality of first reflectors that reflect the first light emitted from the first light source toward the spot lens, and
wherein the first light is reflected to each of the spot lenses respectively disposed at both sides of the spread lens by at least one first reflector among the plurality of reflectors.

4. The lamp of claim 3 , wherein the slope shield is disposed to correspond to the spot lens, which is disposed at one side among the spot lenses respectively disposed at both sides of the spread lens.

5. The lamp of claim 1 , wherein a light emission surface of the lens has a continuous curvature over an entire area or comprises at least one section having a discontinuous curvature.

6. The lamp of claim 1 , further comprising a second beam pattern formation part configured to emit second light that forms a second beam pattern different from the first beam pattern,
wherein the second beam pattern formation part comprises a second light source that emits the second light,
wherein the first beam pattern formation part comprises a first reflector that reflects the first light emitted from the first light source, and
wherein the second beam pattern formation part comprises a second reflector that reflects the second light emitted from the second light source.

7. The lamp of claim 6 , wherein each of the first reflector and the second reflector is provided in plurality,
wherein the plurality of first reflectors and second reflectors are disposed side by side along a longitudinal direction of the lens, and
wherein the first reflectors and the second reflectors are alternately disposed.

8. A lamp for a vehicle, comprising:
a first beam pattern formation part configured to emit first light for a first beam pattern; and
a lens configured to form the first beam pattern by transmitting the first light,
wherein the first beam pattern formation part comprises:
a first light source that emits the first light; and
a shield configured to block a portion of the first light that is emitted from the first light source toward the lens, and

wherein the lens comprises:
a spread lens that concentrates incident light to a focal line having a linear shape; and
a spot lens that concentrates incident light to a point,
wherein the spread lens has an elongated shape in one direction, and the spot lens is disposed at each of both sides of the spread lens.

9. The lamp of claim 8 , wherein the first beam pattern comprises:
a spread pattern; and
a spot pattern, which is smaller than the spread pattern and overlaps the spread pattern, and
wherein the shield comprises:
a spot shield that blocks a portion of light to form the spot pattern; and
a spread shield that blocks a portion of light to form the spread pattern,

wherein the light that passes through the spread lens forms the spread pattern, and the light that passes through the spot lens forms the spot pattern.

10. The lamp of claim 9 , wherein the spot shield comprises:
a boundary shield that blocks a portion of the light to form an upper boundary line of the spot pattern; and
a slope shield that blocks a portion of the light to form the upper boundary line and a slope line of the spot pattern.

11. The lamp of claim 8 , wherein the first beam pattern formation part comprises a plurality of first reflectors that reflect the first light emitted from the first light source toward the spot lens, and
wherein the first light is reflected to each of the spot lenses respectively disposed at both sides of the spread lens by at least one first reflector among the plurality of reflectors.

12. The lamp of claim 11 , wherein the slope shield is disposed to correspond to the spot lens, which is disposed at one side among the spot lenses respectively disposed at both sides of the spread lens.

13. The lamp of claim 8 , wherein a light emission surface of the lens has a continuous curvature over an entire area or comprises at least one section having a discontinuous curvature.

14. The lamp of claim 8 , further comprising a second beam pattern formation part configured to emit second light that forms a second beam pattern different from the first beam pattern,
wherein the second beam pattern formation part comprises a second light source that emits the second light,
wherein the first beam pattern formation part comprises a first reflector that reflects the first light emitted from the first light source, and
wherein the second beam pattern formation part comprises a second reflector that reflects the second light emitted from the second light source.

15. The lamp of claim 14 , wherein each of the first reflector and the second reflector is provided in plurality,
