Abstract

A vehicular light module includes a light source configured to have a position that is adjustable longitudinally along a direction in which light radiates from the light source. The light module also includes a lighting guide that is movably disposed and that is configured to reflect and diffuse the light radiated from the light source. The light module further includes a moving unit configured to move the lighting guide to adjust the reflection and the diffusion of the light radiated from the light source by the lighting guide.

First claim

What is claimed is:

1. A vehicular light module comprising:
a light source configured to have a position that is adjustable longitudinally along a direction in which light radiates from the light source;
a lighting guide that is movably disposed and that is configured to reflect and diffuse the light radiated from the light source;
a moving unit configured to move the lighting guide to adjust the reflection and the diffusion of the light radiated from the light source by the lighting guide; and
a movable plate coupled to the moving unit and configured to connect the moving unit with the lighting guide,
wherein the lighting guide comprises a plurality of guide panels that are hingedly coupled to the movable plate and configured to allow variation of an angle between the plurality of guide panels and the movable plate.

2. The vehicular light module according to claim 1 , further comprising a housing configured to accommodate and mount the light source, the lighting guide, and the moving unit.

3. The vehicular light module according to claim 2 , further comprising a moving guide unit configured to guide a movement of the lighting guide.

4. The vehicular light module according to claim 3 , wherein the moving guide unit comprises:
a first retainer part fitted at one end thereof into a moving slot located in a back surface of the lighting guide; and
a second retainer part positioned opposite to the first retainer part and coupled to a mounting portion provided on the housing via a ball joint connection.

5. The vehicular light module according to claim 1 , wherein the movable plate is configured to connect the moving unit with the light source.

6. The vehicular light module according to claim 1 , wherein the light source and the lighting guide are disposed on a first side of the movable plate facing the direction in which light radiates from the light source, and the moving unit is disposed on a second side of the movable plate facing a direction that is opposite to the direction in which light radiates from the light source.

7. The vehicular light module according to claim 1 , wherein each of the plurality of guide panels is longitudinally adjustable between a square shape and a rectangular shape.

8. The vehicular light module according to claim 1 , wherein each of the plurality of guide panels has a width that increases with increasing distance from the movable plate.

9. The vehicular light module according to claim 1 , wherein the light source comprises:
an LED module configured to generate light having a predetermined luminance;
a diffusing plate configured to diffuse light that is radiated from the LED module;
a back plate coupled to the movable plate and configured to accommodate the LED module and the diffusing plate, the back plate configured to connect the light source to the moving unit; and
an LED cover configured to cover the LED module accommodated in the back plate.

10. The vehicular light module according to claim 9 , wherein the back plate of the light source is integral with the movable plate.

11. The vehicular light module according to claim 1 , wherein the moving unit comprises:
a movable rod coupled at an end thereof to the movable plate; and
a solenoid drive unit configured to move the movable rod.

12. The vehicular light module according to claim 1 , wherein the moving unit is configured to move the light source and the lighting guide between a first configuration corresponding to a tail lighting mode and a second configuration corresponding to a stop lighting mode,
wherein a first surface area of the lighting guide in the first configuration corresponding to the tail lighting mode is smaller than a second surface area of the lighting guide in the second configuration corresponding to the stop lighting mode, as viewed from the direction in which light radiates from the light source.

13. The vehicular light module according to claim 1 , wherein the moving unit is configured to move the light source and the lighting guide between a first configuration corresponding to a tail lighting mode and a second configuration corresponding to a stop lighting mode,
wherein a first diameter defined by outer ends of the plurality of guide panels of the lighting guide in the first configuration corresponding to the tail lighting mode is smaller than a second diameter defined by the outer ends of the plurality of guide panels of the lighting guide in the second configuration corresponding to the stop lighting mode, as viewed from the direction in which light radiates from the light source.

14. A vehicular light module comprising:
a housing disposed at a rear portion of a vehicle body;
at least two light sources disposed in the housing;
a lighting guide that is movably disposed and that is configured to converge and diffuse, in a rearward direction of the vehicle body, light that is radiated from at least one of the at least two light sources; and
a moving unit configured to move the lighting guide to adjust the convergence and the diffusion of the light radiated from the at least two light sources by the lighting guide,
wherein, in a tail lighting mode:
at least one of the at least two light sources is turned on, and
the moving unit moves the lighting guide in a manner such that a first surface area of the lighting guide in a stop lighting mode is larger than a second surface area of the lighting guide in the tail lighting mode, as viewed from a direction in which light radiates from the at least two light sources.

15. The vehicular light module according to claim 14 , further comprising a movable plate coupled to the moving unit and configured to connect the lighting guide to the moving unit,
wherein the at least two light sources comprise at least two of:
a main light source disposed on the movable plate;
a first subsidiary light source disposed on the lighting guide; or
a second subsidiary light source disposed on an inner surface of the housing.

16. The vehicular light module according to claim 15 , wherein:
the first subsidiary light source of the at least two light sources is turned on in the stop lighting mode.
