Abstract

Provided is a grill lighting device for a vehicle including a housing unit positioned on a vehicle body and having a shape whose one side is opened, a light source unit positioned on the housing unit and configured to emit light, a reflective unit provided in the housing unit and configured to reflect light emitted from the light source unit, and a screen unit positioned on the housing unit and configured to cover the opened portion of the housing unit and transmit the light reflected by the reflective unit to generate grill lighting.

First claim

What is claimed is:

1. A grill lighting device for a vehicle, comprising:
a housing unit having an opening and connected to a vehicle body including a grill;
a light source unit positioned on the housing unit and configured to emit light;
a reflective unit positioned in the housing unit and configured to reflect the light emitted from the light source unit; and
a screen unit positioned on the housing unit and configured to cover the opening of the housing unit and transmit the light emitted from the light source unit and reflected by the reflective unit to generate a grill lighting.

2. The grill lighting device of claim 1 , wherein the housing unit is positioned on one of a front, side and rear parts of the vehicle body.

3. The grill lighting device of claim 1 , wherein the housing unit comprises:
a housing rear part at which the reflective unit is positioned;
a housing upper part extending forward from an upper portion of the housing rear part and configured to reflect the light emitted from the light source unit; and
a housing lower part extending forward from a lower portion of the housing rear part, facing the housing upper part and configured to reflect the light emitted from the light source unit.

4. The grill lighting device of claim 1 , wherein the light source unit comprises:
a light source case part positioned on an edge of the housing unit; and
a light source lamp part positioned on the light source case part and configured to emit light to the reflective unit.

5. The grill lighting device of claim 4 , wherein the light source unit further comprises a light source rotating part configured to rotate the light source case part.

6. The grill lighting device of claim 1 , wherein the reflective unit comprises:
a reflective base part;
a plurality of reflective protrusion parts protruding from the reflective base part; and
a reflective surface part positioned at an end of each reflective protrusion part and configured to reflect a portion of the light emitted laterally from the light source unit.

7. The grill lighting device of claim 6 , wherein:
the light source unit is positioned at one edge of the housing unit, and
a protrusion amount of each reflective surface part is proportional to a distance between each reflective surface part and the light source unit.

8. The grill lighting device of claim 6 , wherein:
the light source unit is disposed at both edges of the housing unit, and
a protrusion amount of each reflective surface part is inversely proportional to a distance between each reflective surface part and a center of the reflective base part.

9. The grill lighting device of claim 6 , wherein:
the reflective base part has a planar surface, and
at least some of the reflective protrusion parts adjacent to each other have mutually different lengths.

10. The grill lighting device of claim 6 , wherein:
the reflection base part has a curved surface, and
at least some of the reflective protrusion parts have mutually different lengths.

11. The grill lighting device of claim 1 , wherein the reflective unit and the housing unit are assembled together.

12. The grill lighting device of claim 1 , wherein the reflective unit is integral to the housing unit.

13. The grill lighting device of claim 1 , wherein the screen unit comprises:
a screen body part positioned on the housing unit;
a screen blocking part positioned within the screen body part and configured to block light transmission; and
a screen transmitting part positioned within the screen body part and configured to allow light transmission.
