Abstract

A rotation center decoupling type aiming lamp applied to a vehicle includes an aiming device in which an aiming axis spaced apart from an aiming point reference line of an aiming point axis at a distance of an aiming adjustment height is operated as a rotation center of the reflector, and an aiming angle is changed through an aiming point axis to which the reflector is attached by a reflector bracket, such that the rotation center of the reflector adjusting a light radiation direction may be formed at a position above or ahead of the aiming point reference line, thereby reducing an occupation space of the aiming device and securing stability of the aiming driving, and particularly, a sufficient rear shock absorption space may also be secured in the aiming lamp, thereby securing structural robustness while satisfying low-speed collision regulations.

First claim

What is claimed is:

1. An aiming lamp, comprising:
an aiming point axis forming an aiming point reference line in an internal space of the aiming lamp, and configured to be moved in front and rear directions for adjusting aiming of a light source;
an aiming axis positioned in an upper portion of the internal space of the aiming lamp, and forming an aiming adjustment height with respect to the aiming point reference line; and
a reflector bracket connected to a reflector for reflecting light of the light source, for delivering movement of the aiming point axis, and constituted such that an aiming angle of the light source is changed by an angular motion of the reflector using the aiming axis as a rotation center;
wherein the aiming axis is connected to the reflector by a rotation interval body forming a pivot end,
wherein the rotation interval body is formed with at least one bending portion, and
wherein the bending portion adjust a change in angular motion of the reflector by adjusting a distance of the aiming adjustment height.

2. The aiming lamp of claim 1 ,
wherein the aiming axis forms the rotation center of the reflector with the pivot end having a circular section.

3. The aiming lamp of claim 2 ,
wherein the pivot end is formed with a pivot rotation part, and
wherein the pivot rotation part is formed by combining one or more of a lens positioned ahead of the reflector, a lamp housing forming an internal space in which the reflector is accommodated, or a bezel positioned between lenses of the aiming lamp.

4. The aiming lamp of claim 3 ,
wherein two or more of the lens, the lamp housing, or the bezel are formed with hemispheric section grooves surrounding a circular section portion of the pivot end on both sides thereof.

5. The aiming lamp of claim 4 ,
wherein the hemispheric section groove forms an aiming movement gap with respect to the circular section portion of the pivot end.

6. The aiming lamp of claim 5 ,
wherein the aiming movement gap provides movement to the aiming axis to secure a space in which the reflector is aimed.

7. The aiming lamp of claim 1 ,
wherein the aiming axis forms the rotation center of the reflector with a curved end.

8. The aiming lamp of claim 7 ,
wherein the curved end forms a virtual focus for the reflector.

9. The aiming lamp of claim 7 ,
wherein the curved end is constituted by combining one or more of a lens positioned ahead of the reflector, a lamp housing forming an internal space in which the reflector is accommodated, or a bezel positioned between lenses of the aiming lamp.

10. The aiming lamp of claim 8 ,
wherein two or more of the lens, the lamp housing, or the bezel are formed with curved surfaces instead of closely contacting the curved end on both sides thereof.

11. The aiming lamp of claim 1 ,
wherein the aiming axis is coupled to an aiming axis bracket, and
wherein the aiming axis bracket is fixed to a lamp housing forming an internal space in which the reflector is accommodated.

12. The aiming lamp of claim 11 ,
wherein the aiming axis bracket protrudes toward the reflector to surround a pivot end of the aiming axis.

13. The aiming lamp of claim 11 ,
wherein the aiming axis bracket is fastened to the aiming lamp housing by a screw.

14. A vehicle, comprising the aiming lamp of claim 1 ,
wherein the rotation center of the aiming axis forms a moment distance of the reflector, and the aiming angle of the light source is changed by the angular motion of the reflector at the moment distance.

15. The vehicle of claim 14 ,
wherein the aiming lamp changes the aiming angle by an aiming device, and
wherein the aiming device forms a pivot rotation part by surrounding the pivot end of the aiming axis by a combination of one or more of a lens positioned ahead of the reflector, a lamp housing forming an internal space of the aiming lamp in which the reflector is accommodated, or a bezel positioned between lenses of the aiming lamp.

16. The vehicle of claim 15 ,
wherein the aiming lamp is a fog lamp, and
wherein the fog lamp is applied with a lens aiming device forming the pivot rotation part by the lens and the lamp housing or a bezel aiming device forming the pivot rotation part by the bezel and the lamp housing.

17. The vehicle of claim 15 ,
wherein the aiming lamp is a fog lamp, and
wherein the fog lamp is applied with a forward movement aiming device in which the pivot rotation part is formed by the lens and the lamp housing or the bezel and the lamp housing, and each of the lens and the bezel is formed with a housing connection part coupled to the lamp housing.

18. The vehicle of claim 15 ,
wherein the aiming lamp is a fog lamp, and
wherein the fog lamp is applied with a virtual focus aiming device in which the pivot rotation part is formed by the lens and the lamp housing or the bezel and the lamp housing, and a virtual focus for the reflector is formed.

19. The vehicle of claim 15 ,
wherein the aiming lamp is a fog lamp, and
wherein the fog lamp is applied with a housing aiming device in which the pivot rotation part is formed by an aiming axis bracket coupled to the aiming axis and fixed to the lamp housing.

20. The vehicle of claim 15 ,
wherein the aiming lamp is a headlamp, and
wherein the headlamp is applied with a semi aiming device in which a semi aiming axis connected to a high beam aiming device is provided, and the semi aiming axis is connected to the aiming axis by a pivot bracket.
