Abstract

A warning device for a vehicle is provided. The warning device comprises a main body including a lateral side and a bottom side, a first light device configured on the main body and emitting a first light toward the lateral side, and at least one of a second light device and a laser module configured on the main body and emitting a second light toward the bottom side.

Claims

1. A warning device for a vehicle, comprising:

a main body including a lateral side and a bottom side;

a warning light device configured on the main body and emitting a warning light toward the lateral side; and

at least one of an auxiliary illumination light device and a laser module configured on the main body and emitting an auxiliary light toward the bottom side.

2. A warning device of claim 1, wherein when the warning device comprises the auxiliary illumination light device, the auxiliary light is an auxiliary illumination light, when the warning device comprises the laser module, the auxiliary light is a laser light, and when the warning device comprises both the auxiliary illumination light device and the laser module, the auxiliary light includes at least one of the auxiliary illumination light and the laser light.

3. A warning device for a first vehicle, comprising:

a main body including a lateral side and a bottom side;

a first light device configured on the main body and emitting a first light toward the lateral side; and

at least one of a second light device and a laser module configured on the main body and emitting a second light toward the bottom side.

4. A warning device of claim 3, wherein the first light is a warning light, when the warning device comprises the second light device, the second light is an auxiliary illumination light, when the warning device comprises the laser module, the second light is a laser light, and when the warning device comprises both the second light device and the laser module, the second light includes at least one of the auxiliary illumination light and the laser light.

5. A warning device of claim 3, wherein when the warning device comprises the laser module, the second light is a laser light emitted onto a ground and outlining a safe distance between the first vehicle and a second vehicle.

6. A warning device of claim 3, further comprising a control system configured on the main body.

7. A warning device of claim 6, wherein the control system includes a sensing unit detecting an information being one selected from the group consisting of an image of a second vehicle, a distance between the first vehicle and the second vehicle, a speed of the second vehicle and a combination thereof.

8. A warning device of claim 7, wherein the control system further includes a warning unit coupled to the sensing unit and providing a warning signal under a predetermined condition.

9. A warning device of claim 8, wherein the control system further includes a data processing and controlling unit coupled to the sensing unit and the warning unit and determining whether the detected information conforms to the predetermined condition.

10. A warning device of claim 8, wherein the warning signal is one selected from a group consisting of a warning sound, a continuous lighting of the first light, a twinkle of the first light, a continuous lighting of the second light, a twinkle of the second light and a combination thereof.

11. A warning device of claim 8, wherein the predetermined condition is at least one that the distance between the first vehicle and the second vehicle is less than a predetermined distance and the speed of the second vehicle is higher than a predetermined speed.

12. A warning device of claim 11, wherein the second light is a laser light emitted onto a ground and the predetermined distance is equal to a distance between the first vehicle and the laser light.

13. A warning device of claim 11, wherein the second light is a laser light emitted onto a ground and the predetermined distance is less than a distance between the first vehicle and the laser light on the ground.

14. A warning device of claim 3, further comprising a case containing the main body.

15. A warning device of claim 14, wherein the case includes a transparent bottom and the second light passes through the transparent bottom.

16. A warning device of claim 14, wherein the case includes a hollow bottom and the second light passes through the hollow bottom.

17. A warning device of claim 14, wherein the case includes an inner surface and plural refractive slots configured on the inner surface.

18. A warning method for a first vehicle, comprising:

providing a main body including a lateral side and a bottom side;

emitting a first light from the main body toward the lateral side; and

emitting a second light from the main body toward the bottom side.

19. A warning method of claim 18, wherein the second light is emitted onto a ground and outlines a safe distance between the first vehicle and a second vehicle.

20. A warning method of claim 18, wherein the second light is emitted onto a ground to explore a condition of the ground.
