Abstract

A light distributing device for a vehicle includes a focusing lens that concentrates light input to a rear surface thereof to form an image point on a front side thereof, a shield that is arranged at the image point and has an opening through which a portion of the light, which passes through the image point, passes, and a mirror that reflects at least a portion of the light that passed through the opening to the front side of the focusing lens.

First claim

What is claimed is:

1. A light distributing device for a vehicle comprising:
a focusing lens that concentrates light input to a rear surface thereof to form an image point on a front side thereof;
a shield that is arranged at the image point and has an opening through which a portion of the light, which passes through the image point, passes; and
a mirror that reflects at least a portion of the light that passed through the opening to the front side of the focusing lens.

2. The light distributing device of claim 1 , wherein a front surface of the focusing lens is a flat surface and the shield is parallel to the front surface of the focusing lens.

3. The light distributing device of claim 1 , wherein the shield has a plurality of openings.

4. The light distributing device of claim 1 , wherein the focusing lens, the shield, and the mirror are arranged in a sequence of the focusing lens, the shield, and the mirror along a direction in which the light input to the rear surface of the focusing lens is output.

5. The light distributing device of claim 1 , wherein a front surface of the focusing lens is a flat surface and the mirror is perpendicular to the front surface of the focusing lens.

6. The light distributing device of claim 1 , wherein the mirror comprises a reflective surface that reflects the light that passes through the image point and the reflective surface of the mirror is spaced apart from an optical axis of the focusing lens by a predetermined distance.

7. The light distributing device of claim 1 , further comprising:
a collimator lens that is arranged on a rear side of the focusing lens to output the light input to a rear surface thereof as parallel rays.

8. The light distributing device of claim 7 , wherein a front surface of the focusing lens is a flat surface, the rear surface of the collimator lens is a flat surface, and the front surface of the focusing lens and the rear surface of the collimator lens are parallel to each other.

9. The light distributing device of claim 1 , further comprising:
a projection lens that is arranged on the front side of the focusing lens.

10. The light distributing device of claim 9 , wherein a front surface of the focusing lens is a flat surface, the rear surface of the projection lens is a flat surface, and the front surface of the focusing lens and the rear surface of the projection lens are parallel to each other.

11. The light distributing device of claim 9 , wherein the focusing lens forms a focus on the front side thereof, and the focus is situated between the projection lens and the focusing lens.

12. The light distributing device of claim 9 , wherein the focusing lens, the shield, the mirror, and the projection lens are arranged in a sequence of the focusing lens, the shield, the mirror, and the projection lens along a direction in which the light input to the rear surface of the focusing lens is output.

13. The light distributing device of claim 1 , wherein one side of the mirror is attached to the shield.

14. The light distributing device of claim 1 , wherein the mirror and the shield are perpendicular to each other.

15. The light distributing device of claim 1 , wherein the shield comprises a main shield that has an opening, and a mirror shield which blocks a portion of the opening and on which the mirror is mounted.

16. The light distributing device of claim 1 , wherein a seating part protrudes from the shield and the mirror is seated on the seating part.

17. The light distributing device of claim 1 , further comprising:
a mirror elevating device that elevates the mirror.

18. The light distributing device of claim 1 , further comprising:
a mirror rotating device that rotates the mirror about a rotational axis,
wherein the rotational axis is perpendicular to the shield.

19. The light distributing device of claim 1 , further comprising:
a mirror rotating device that rotates the mirror about a rotational axis,
wherein the rotational axis is parallel to an optical axis of the focusing lens.

20. A vehicle comprising the light distributing device claimed in claim 1 .
