Abstract

A grille lighting system includes a light emitting lamp that includes one or more walls defining an inner space isolated from outside, a light emitting material disposed in the inner space and configured to emit light when the light emitting material contacts air, and a shutter disposed on the one or more walls, wherein the shutter is configured to be opened to allow introduction of outside air to the inner space from outside and further configured to be closed to block introduction of outside air to the inner space. The system further includes a controller configured to control operation of the shutter and cause the shutter to be opened and closed such that when the shutter is opened, the outside air is introduced to contact the light emitting material, which causes the light emitting material to emit light.

First claim

What is claimed is:

1. A grille lighting system comprising:
a light emitting lamp comprising:
one or more walls defining an inner space isolated from outside,
a light emitting material disposed in the inner space, the light emitting material emitting light by bioluminescence,
a shutter disposed on the one or more walls, wherein the shutter opens to allow introduction of outside air to the inner space from outside and further closes to block the introduction of outside air to the inner space, and
a lens and a connector coupled to the lens, wherein the lens and the connector form the one or more walls defining the inner space; and

a controller configured to control operation of the shutter and cause the shutter to be opened and closed, wherein opening the shutter introduces outside air to contact the light emitting material, which causes the light emitting material to emit light.

2. The grille lighting system of claim 1 , wherein the light emitting material is configured to emit the light by bioluminescence.

3. The grille lighting system of claim 2 , wherein the light emitting material comprises luciferin.

4. The grille lighting system of claim 1 , wherein the light emitting lamp further comprises a grille illuminator that comprises the shutter and the light emitting material.

5. The grille lighting system of claim 1 , wherein the light emitting lamp further comprises a light emitter container and a light emitter cover coupled to the connector to form the inner space.

6. The grille lighting system of claim 5 , wherein the shutter is provided in the light emitter cover to close or open the inner space.

7. The grille lighting system of claim 6 , wherein the shutter is located at the front surface of the light emitter cover.

8. The grille lighting system of claim 1 , wherein the light emitting lamp further comprises a light emitter container placed in a space formed by the connector and the lens coupled to each other.

9. The grille lighting system of claim 8 , wherein the shutter is provided in a wall of the connector.

10. The grille lighting system of claim 1 , wherein the light emitting material is attached to the connector.

11. The grille lighting system of claim 10 , wherein the light emitting material is coated on a boss of the connector.

12. The grille lighting system of claim 11 , wherein the boss protrudes to the inner space.

13. The grille lighting system of claim 10 , wherein the shutter is provided in a lens body of the lens.

14. A vehicle comprising:
a radiator grille; and
the grille lighting system of claim 1 attached to the radiator grille and comprising the light emitting lamp for lighting at least a portion of the radiator grille.

15. The vehicle of claim 14 , wherein the grille lighting system comprises an additional light emitting lamp for lighting an emblem.

16. The vehicle of claim 14 , wherein the grille lighting system comprises the controller.

17. The vehicle of claim 16 , wherein the controller includes a data map associated with an output of a control signal to the shutter and the data map constructs a table for external illuminance, sunset time, and day/night.

18. The vehicle of claim 16 , further comprising an operation button circuit is configured to transmit a signal to the controller.
