Abstract

The present invention provides an optical structure for a vehicle, including: an optic unit which is configured by a plurality of optics; a lens which is provided with an interval from the optic unit; and a shield which is provided between the optic unit and the lens to reflect light which passes through the optic toward the lens.

Claims

1. An optical structure for a vehicle, comprising:

an optic unit which is configured by a plurality of optics;

a lens which is provided with an interval from the optic unit; and

a shield which is provided between the optic unit and the lens to reflect light which passes through the optic toward the lens.

2. The optical structure of claim 1, wherein a reflective surface which reflects the light which passes through the optic toward the lens is provided on a top surface of the shield.

3. The optical structure of claim 1, wherein the optic unit is configured such that three optics are disposed with an interval.

4. The optical structure of claim 1, wherein the lens is an aspherical lens.

5. The optical structure of claim 4, wherein the lens is a semicircular aspherical lens having upper and lower cut surfaces.

6. The optical structure of claim 1, wherein the optic includes:

a spherical curve which is provided on a rear surface of a conical optic;

an entrance which is provided on an entire surface of an optic which is opposite to the spherical curve; and

an aspherical curve which is provided in the entrance.

7. The optical structure of claim 6, wherein an outer surface of the optic forms a Bezier curve.

8. The optical structure of claim 1, wherein a diameter of a rear surface of the optic is 20 mm.

9. The optical structure of claim 5, wherein a width of the lens is 70 mm to 80 mm.

10. The optical structure of claim 1, wherein the optic is formed to be tilted so that a center of the spherical curve faces a lens focal point.

11. The optical structure of claim 6, wherein a distance between a center of the front surface of the optic and the lens focal point is determined by a value calculated by an operation.

12. The optical structure of claim 11, wherein a distance between the center of the front surface of the optic and the lens focal point is calculated by the operation and the calculated value is applied to a table to determine a control range of the optic.
