Abstract

An indirect lighting structure for a vehicle roof provides indirect lighting to at least a part of a roof glass through a light guide formed along a guide rail. The indirect lighting structure includes: a guide rail configured to support a roof glass positioned on the guide rail; a light source unit positioned at one end in a longitudinal direction of the guide rail; and a light guide which is configured to be in contact with the light source unit and positioned along the guide rail, in which the light guide is configured such that at least a part of the light guide is in contact with and inserted into the guide rail so as to guide light introduced from the light source to illuminate a pattern portion.

First claim

What is claimed is:

1. An indirect lighting structure for a vehicle roof, the indirect lighting structure comprising:
a guide rail configured to support a roof glass positioned on the guide rail;
a light source unit positioned at one end in a longitudinal direction of the guide rail;
a light guide which is configured to be in contact with the light source unit and positioned along the guide rail; and
a reflective portion which is configured to face the light guide,
wherein the light guide is arranged such that at least a part of the light guide is in contact with and inserted into the guide rail so as to guide light introduced from the light source to illuminate a pattern portion, and
wherein light reflected by the reflective portion illuminates the pattern portion.

2. The indirect lighting structure of claim 1 , wherein the pattern portion is positioned on at least one of the roof glass and a roll blind which is configured inside the vehicle along the roof glass.

3. The indirect lighting structure of claim 1 , wherein the guide rail further includes a blocking portion which protrudes from a lower surface of the light guide toward an interior of the vehicle.

4. The indirect lighting structure of claim 3 , wherein a protruding end of the blocking portion is positioned to be curved toward the roof glass at a predetermined angle.

5. The indirect lighting structure of claim 1 , further comprising:
a guide cover which is positioned on the guide rail in order to set a path of light emitted from the light guide.

6. The indirect lighting structure of claim 1 , wherein the reflective portion has a concave lens shape configured to face the light guide.

7. The indirect lighting structure of claim 1 , wherein the reflective portion is positioned on the guide rail.

8. The indirect lighting structure of claim 1 , wherein the light, which illuminates the pattern portion through the light guide, has an illumination angle of 20° to 60°.

9. The indirect lighting structure of claim 1 , wherein the pattern portion is configured within a predetermined region from an inner end of the guide rail.
