Abstract

A lamp for a moving vehicle which can function as a headlamp and as a lower-brightness running lamp includes a single light emitting device, a power regulator, a first lampshade, a light guiding element, a lifting device, and a number of first reflecting covers. The first lampshade is arranged facing the light emitting device. The light guiding element gathers light from the light source and emits the light from a lower part of the moving vehicle and the power regulator can supply full power or reduced power to the light source. The lifting device holds the light guiding element and can raise it up or down so that emitted light reaches either the first lampshade or reaches first reflecting covers depending on the lighting function required.

First claim

What is claimed is:

1. A traffic signal lamp comprising:
a light emitting device;
a first lampshade being arranged facing the light emitting device;
a light guiding element comprising a light guiding body and a plurality of light guiding branches connected with the light guiding body, the light guiding body comprising a light incident end, each light guiding branch comprising a light emitting end, the light incident end facing the light emitting device, the light emitting ends opposite to the light incident end, and the light emitting ends being arranged below the light incident end;
a lifting device being arranged between the light emitting device and the first lampshade; the lifting device being configured for clamping the light guiding element and driving the light guiding element to move;
a plurality of first reflecting covers, each first reflecting cover comprising a bottom opening, the light emitting ends being inserted in the bottom opening, and the lifting device configured for controlling the light guiding element to rise up or drop, thereby causing light emitted from the light emitting device to reach the first lampshade or the first reflecting covers.

2. The traffic signal lamp of claim 1 , wherein the light emitting device comprises a second reflecting cover, a lamp base and a light source, the lamp base is arranged at the bottom of the second reflecting cover, the light source is mounted on the lamp base.

3. The traffic signal lamp of claim 2 , wherein the second reflecting cover comprises a first inner surface, the first inner surface is parabolic or elliptic.

4. The traffic signal lamp of claim 3 , wherein the second reflecting cover comprises a focal point, the light incident end is located at the focal point.

5. The traffic signal lamp of claim 4 , further comprising a first baffle plate, the first baffle plate located between the light emitting device and the light guiding body, and below the light incident end, the first baffle plate configured for preventing the light from illuminating the upper part of the first lampshade.

6. The traffic signal lamp of claim 5 , wherein the lifting device comprises a fixing plate, a connecting arm and a clamp end, the connecting arm connecting the fixing plate and the clamp end, the fixing plate is arranged behind the first baffle plate, the connecting arm movable relative to the fixing plate along the vertical direction, and the clamp end is configured for fixing the light guiding element.

7. The traffic signal lamp of claim 6 , further comprising a second baffle plate, the second baffle plate fixed on the connecting arm, and capable of rotating around the connecting arm.

8. The traffic signal lamp of claim 7 , further comprising an output power regulator, wherein the output power regulator is mounted on the light emitting device, and configured for adjusting the power of the light emitting device.

9. The traffic signal lamp of claim 1 , wherein the light source is a light bulb.

10. The traffic signal lamp of claim 1 , further comprising a plurality of second lampshades, wherein each of the second lampshade matches with corresponding one of the first reflecting covers.

11. The traffic signal lamp of claim 1 , wherein the light guide element is a solid plastic pipe.

12. A motor vehicle, comprising:
a vehicle body;
a vehicle head connected with the vehicle body; and
at least one traffic signal lamp mounted on the vehicle head, each of the traffic signal lamp comprising:
a light emitting device;
a first lampshade being arranged facing the light emitting device;
a light guiding element comprising a light guiding body and a plurality of light guiding branches connecting with the light guiding body, the light guiding body comprising a light incident end, each light guiding branch comprising a light emitting end, the light incident end facing the light emitting device, the light emitting ends opposite to the light incident ends, and the light emitting end being arranged below the light incident end;
a lifting device being arranged between the light emitting device and the first lampshade; the lifting device being configured for clamping the light guiding element and driving the light guiding element to move;
a plurality of first reflecting covers, each first reflecting cover comprising a bottom opening, the light emitting ends being inserted in the bottom opening, and the lifting device configured for controlling the light guiding element to rise up or drop, so as to cause light emitting from the light emitting device to reach the first lampshade or the first reflecting covers.

13. The motor vehicle of claim 12 , wherein the light emitting device comprises a second reflecting cover, a lamp base and a light source, the lamp base is arranged at the bottom of the reflecting cover, the light source is electrically connected with the lamp base.

14. The motor vehicle of claim 13 , wherein the second reflecting cover comprises a focal point, the light incident end is located at the focal point.

15. The motor vehicle of claim 12 , wherein the reflecting cover comprises a first inner surface, the first inner surface is parabolic or elliptic.

16. The motor vehicle of claim 12 , further comprising a first baffle plate, the first baffle plate is located between the light emitting device and the light guiding body, and below the light incident end, the first baffle plate configured for preventing the light from illuminating the upper part of the first lampshade.

17. The motor vehicle of claim 12 , wherein the lifting device comprises a fixing plate, a connecting arm and a clamp end, the connecting arm connecting the fixing plate and the clamp end, the fixing plate is arranged behind the first baffle plate, the connecting arm movable relative to the fixing plate along the vertical direction, and the clamp end is configured for fixing the light guiding element.

18. The motor vehicle of claim 12 , further comprising a second baffle plate, the second baffle plate fixed on the connecting arm, and capable of rotating around the connecting arm.

19. The motor vehicle of claim 12 , further comprising an output power regulator, wherein the output power regulator is mounted on the light emitting device, and configured for adjusting the power of the light emitting device.

20. The motor vehicle of claim 12 , further comprising a plurality of second lampshades, wherein each of the second lampshade matches with corresponding one of the first reflecting cover.
