Abstract

A tail lamp device that is mountable on a rear fender of a motorcycle is disclosed. The tail lamp device includes a tail lamp that is attached to the rear fender. The tail lamp includes a substrate and a plurality of light emitting elements such as LEDs mounted on the substrate, and the substrate is disposed along a rearwardly descending surface of the rear fender.

Claims

1. A tail lamp device that is mountable on a rear fender of a motorcycle, the tail lamp device comprising:

a tail lamp that is attached to the rear fender, wherein the tail lamp includes a substrate and a plurality of light emitting elements mounted on the substrate, and the substrate is disposed along a rearwardly descending surface of the rear fender.

2. A tail lamp device according to claim 1, wherein the tail lamp includes at least one lens that covers the plurality of light emitting elements and has a directivity that rearwardly directs light emitted from the plurality of light emitting elements.

3. A tail lamp device according to claim 1, wherein the light emitting elements are LED elements.

4. A tail lamp device according to claim 1, wherein the rear fender includes a mounting concave section, and circuit elements for the light emitting elements that are mounted on the substrate are positioned in the mounting concave section.

5. A tail lamp device that is mountable on a rear fender of a motorcycle, the tail lamp device comprising:

a lamp substrate disposed along a sloped surface angled from a vertical line; and

a plurality of light emitting elements mounted on the lamp substrate.

6. A tail lamp device according to claim 5, wherein the plurality of light emitting elements extend in a direction generally perpendicular to the substrate.

7. A tail lamp device according to claim 6, wherein the light emitting elements are LED elements.

8. A tail lamp device according to claim 6, further comprising a lens unit that covers the plurality of light emitting elements and rearwardly directs light emitted from the light emitting elements generally in a horizontal direction.

9. A tail lamp device according to claim 5, further comprising a circuit substrate having circuit elements for the light emitting elements, wherein the rear fender includes a mounting concave section, and the circuit substrate is placed in the mounting concave section.

10. A tail lamp device according to claim 9, wherein the lamp substrate covers the circuit substrate.

11. A tail lamp device that is mountable on a rear fender of a motorcycle, the tail lamp device comprising:

a concave mounting section formed in a rearwardly sloped surface of the rear fender;

a lamp substrate that substantially covers the concave mounting section and is disposed along a rearwardly sloped surface of the rear fender;

a plurality of light emitting elements mounted on the lamp substrate; and

a circuit substrate for at least the light emitting elements, disposed in the concave mounting section below the lamp substrate.

12. A tail lamp device according to claim 11, further comprising at least one lens that covers the plurality of light emitting elements and has a directivity that rearwardly directs light emitted from the plurality of light emitting elements in a horizontal direction.

13. A tail lamp device according to claim 11, wherein the light emitting elements are LED elements.

14. A tail lamp device for a vehicle, comprising:

a housing;
