Abstract

A lamp device for a vehicle is provided. The lamp device includes a light source, a lamp housing that accommodates the light source thereon. A lens is coupled to the lamp housing to allow light emitted from the light source to penetrate the lens and a bezel is coupled to the lamp housing and is disposed between the lens and the light source. In particular, the bezel has a surface structure formed on a rear surface thereof and is configured to reflect irradiated light. The bezel is formed in a color that is complementary to a color of the lens.

First claim

What is claimed is:

1. A lamp device for a vehicle, comprising:
a light source;
a lamp housing that accommodates the light source thereon;
a lens coupled to the lamp housing to allow light emitted from the light source to penetrate the lens; and
a bezel coupled to the lamp housing and disposed between the lens and the light source, wherein a distance between a center of mass of the bezel and a center of mass of the light source is shorter than a distance between the center of mass of the light source and a center of mass of the lens,
wherein the lens includes a first color and the bezel includes a second color that is complimentary to the first color,
wherein the second color is blue-green,
wherein the light emitted from the light source penetrates the bezel and is changed in color according to a correction color of the bezel and reaches the lens, and
wherein the correction color is mixed with the first color of the lens to generate dark regions on the lens; wherein the rear surface of the bezel is formed to have a multi focus reflector (MFR) surface configured to reflect the light emitted from the light source at a reflection angle equal to an incident angle, and wherein the light directed toward the bezel is repeatedly reflected between the bezel and the lamp housing by the multi focus reflector (MFR) surface.

2. The lamp device for the vehicle of claim 1 , wherein the first color is red.

3. The lamp device for the vehicle of claim 2 , wherein the lens transmits light having wave lengths equal to or greater than about 597 nm.

4. The lamp device for the vehicle of claim 1 , wherein the bezel transmits light having wave lengths equal to or less than 540 nm.

5. The lamp device for the vehicle of claim 1 , wherein the rear surface of the bezel is formed to have a rear reflector (RR) shape by which the light emitted from the light source is substantially reflected rearward.
