Abstract

A lamp for a vehicle is provided and includes a first lamp module having an interior lens and at least one first light source. The first light source is configured to emit light toward the interior lens. Additionally, a second lamp module is disposed on a first side of the first lamp module and emits light and a third lamp module is disposed on a second side of the first lamp module and emits light and has an emission area that is different from the second lamp module.

Claims

1. A lamp for a vehicle, comprising:

a first lamp module including an interior lens and at least one first light source, configured to emit light toward the interior lens;

a second lamp module disposed on a first side of the first lamp module and configured to emit light; and

a third lamp module disposed on a second side of the first lamp module, configured to emit light, and having a different emission area from the second lamp module,

wherein the second lamp module having at least one second light source, configured to emit light, a first half mirror, configured to transmits a portion of the light emitted from the second light source therethrough and configured to reflect a residual portion of the emitted light, and a first reflector, positioned adjacent to the first half mirror and configured to reflect the light reflected from the first half mirror back to the first half mirror, and the third lamp module having at least one third light source, configured to emit light, a second half mirror, configured to transmit a portion of the light emitted from the third light source therethrough and configured to reflect a remaining portion of the emitted light, and a second reflector, positioned adjacent to the second half mirror and configured to reflect the light reflected from the second half mirror back to the second half mirror, and

wherein the first reflector is disposed parallel to the first half mirror and the second reflector is disposed parallel to the second half mirror.

2. The lamp of claim 1, wherein the first half mirror includes a first extension portion, which extends farther than the first reflector toward the interior lens, and the second half mirror includes a second extension portion, which extends farther than the second reflector toward the interior lens.

3. The lamp of claim 2, wherein the light emitted from the second light source is incident upon the first extension portion and the light emitted from the third light source is incident upon the second extension portion.

4. The lamp of claim 1, wherein the third light source is positioned proximate to the second light source.

5. The lamp of claim 1, wherein the second light source is disposed at a rear portion of the interior lens so as for the light emitted therefrom to be incident upon the first half mirror through the interior lens and the third light source is disposed at a rear portion of the interior lens so as for the light emitted therefrom to be incident upon the second half mirror through the interior lens.

6. The lamp of claim 1, further comprising:

a first light guide configured to emit the light from the second light source toward the first half mirror; and

a second light guide configured to emit the light from the third light source toward the second half mirror.

7. The lamp of claim 6, wherein the second light guide is positioned proximate to the first light guide.

8. The lamp of claim 1, wherein the first half mirror and the first reflector form a first original image and one or more first repetition images that are reflections of the first original image with the light emitted from the second light source, and the second half mirror and the second reflector form a second original image and one or more second repetition images, which are reflections of the second original image, with the light emitted from the third light source.

9. The lamp of claim 8, wherein the first half mirror and the first reflector form the first repetition images along a first direction and the second half mirror and the second reflector form the second repetition images along a second direction.

10. A lamp for a vehicle, comprising:

a first lamp module including an interior lens and at least one first light source, configured to emit light toward the interior lens;

a second lamp module disposed on a first side of the first lamp module and configured to emit light; and

a third lamp module disposed on a second side of the first lamp module, configured to emit light, and having a different emission area from the second lamp module,

wherein the second lamp module having at least one second light source, configured to emit light, a first half mirror, configured to transmits a portion of the light emitted from the second light source therethrough and configured to reflect a residual portion of the emitted light, and a first reflector, positioned adjacent to the first half mirror and configured to reflect the light reflected from the first half mirror back to the first half mirror, and the third lamp module having at least one third light source, configured to emit light, a second half mirror, configured to transmit a portion of the light emitted from the third light source therethrough and configured to reflect a remaining portion of the emitted light, and a second reflector, positioned adjacent to the second half mirror and configured to reflect the light reflected from the second half mirror back to the second half mirror, and

wherein the second light source is disposed at a rear portion of the interior lens so as for the light emitted therefrom to be incident upon the first half mirror through the interior lens and the third light source is disposed at a rear portion of the interior lens so as for the light emitted therefrom to be incident upon the second half mirror through the interior lens.

11. The lamp of claim 10, wherein the first half mirror includes a first extension portion, which extends farther than the first reflector toward the interior lens, and the second half mirror includes a second extension portion, which extends farther than the second reflector toward the interior lens.

12. The lamp of claim 11, wherein the light emitted from the second light source is incident upon the first extension portion and the light emitted from the third light source is incident upon the second extension portion.

13. The lamp of claim 10, wherein the third light source is positioned proximate to the second light source.

14. The lamp of claim 10, wherein the first reflector is disposed in parallel to the first half mirror and the second reflector is disposed in parallel to the second half mirror.

15. The lamp of claim 10, wherein the first half mirror and the first reflector form a first original image and one or more first repetition images that are reflections of the first original image with the light emitted from the second light source, and the second half mirror and the second reflector form a second original image and one or more second repetition images, which are reflections of the second original image, with the light emitted from the third light source.

16. The lamp of claim 15, wherein the first half mirror and the first reflector form the first repetition images along a first direction and the second half mirror and the second reflector form the second repetition images along a second direction.
