Abstract

Disclosed is a vehicle lamp which irradiates a desired color by mixing colors of light by using a colored light source or a light guide including a color layer or the like. A color light guide applying lamp for vehicle includes a light source which irradiates light of a first color, a light guide, at least one portion of which exhibits a second color, wherein after passing through the light guide, the light of the first color exhibits a third color by mixing the first color and the second color.

Claims

1. A color light guide applying lamp for vehicle, comprising:

a light source configured to irradiate a first color of light; and

a light guide, at least one portion of which exhibits a second color,

wherein after passing through the light guide, the first color of light exhibits a third color of light by mixing the first color of light and the second color of light.

2. The color light guide applying lamp for vehicle of claim 1, wherein the light guide includes a colorless guide unit which transmits the first color of light;

and a light guide color layer which exhibits the second color and transmits the first color of light having passed through the guide unit.

3. The color light guide applying lamp for vehicle of claim 2, wherein the light guide and the light guide color layer are formed to overlap each other in a transmission direction of the first color of light passing through the light guide color layer.

4. The color light guide applying lamp for vehicle of claim 2, wherein the guide unit is located on an inside of the lamp, the light guide color layer is located on an outside of the lamp, and the lamp exhibits the second color on the outside when the light source is off.

5. The color light guide applying lamp for vehicle of claim 2, wherein the guide unit and the light guide color layer are formed integrally by double injection.

6. The color light guide applying lamp for vehicle of claim 1, wherein one of the first color and the second color is yellow and the other one is blue.

7. The color light guide applying lamp for vehicle of claim 1, wherein the third color is white and the lamp is a position lamp.

8. The color light guide applying lamp for vehicle of claim 1, wherein the first color and the second color are complementary to each other.

9. The color light guide applying lamp for vehicle of claim 1, further comprising a filter having a fourth color between the light source and the light guide.

10. The color light guide applying lamp for vehicle of claim 9, wherein at least one of the first color and the fourth color is yellow.

11. The color light guide applying lamp for vehicle of claim 2, wherein the light guide color layer is a first light guide color layer, and the light guide further includes a second light guide color layer having a fourth color at a predetermined position of the guide unit on which light from the light source is incident.

12. The color light guide applying lamp for vehicle of claim 11, wherein the fourth color is yellow, and the guide unit, the first light guide color layer and the second light guide color layer are formed integrally by double injection.

13. A color light guide applying lamp for vehicle, comprising:

a light source configured to irradiate white light;

a light guide, at least one portion of which exhibits a first color other than white; and

an external color layer which exhibits a second color other than white,

wherein the white light sequentially passes through the light guide and the external color layer to exhibit a third color by mixing the first color and the second color.

14. The color light guide applying lamp for vehicle of claim 13, wherein the light guide includes a colorless guide unit which transmits the white light;

and a light guide color layer which exhibits the first color and transmits the white light having passed through the guide unit.

15. The color light guide applying lamp for vehicle of claim 14, wherein the light guide and the light guide color layer are formed to overlap each other in a transmission direction of the white light passing through the light guide color layer.

16. The color light guide applying lamp for vehicle of claim 14, wherein the guide unit, the light guide color layer and the external color layer are sequentially located from an inside to an outside of the lamp, and the lamp exhibits the second color on the outside when the light source is off.

17. The color light guide applying lamp for vehicle of claim 13, wherein one of the first color and the second color is green and the other one is red.

18. The color light guide applying lamp for vehicle of claim 13, wherein the third color is yellow and the lamp is a turn signal lamp.

19. The color light guide applying lamp for vehicle of claim 13, wherein one of the first color and the second color is red and the other one is sky blue.

20. The color light guide applying lamp for vehicle of claim 13, wherein the third color is white and the lamp is a backup lamp.

21. The color light guide applying lamp for vehicle of claim 14, wherein the guide unit and the light guide color layer are formed integrally by double injection.

22. The color light guide applying lamp for vehicle of claim 13, wherein the first color and the second color are complementary to each other.
