Abstract

To provide a lighting apparatus arrangement for a saddle riding vehicle, allowing a predetermined illumination distance and illumination range of laser light to be easily achieved. A lighting apparatus includes a laser device, a first light guide, and a front-portion light emitting unit. The laser device emits laser light. The first light guide guides light from the laser device to any desired position. The front-portion light emitting unit is disposed at a distal end of the first light guide and irradiates areas around a vehicle with light from the first light guide. The front-portion light emitting unit is disposed at a position higher in level than a lower end of a meter unit disposed at a front portion of a vehicle body.

First claim

The invention claimed is:

1. A saddle riding vehicle, comprising:
a lighting apparatus, wherein the lighting apparatus comprises:
a laser light source that emits light;
a light guide that guides light from the laser light source to any desired position;
at least one light emitting unit disposed at a distal end of the light guide, the light emitting unit irradiating areas around the vehicle with light from the light guide, and
a rearview mirror extending upward at a front portion of a vehicle body, wherein

the light emitting unit
is disposed at a position higher in level than a lower end of a meter unit disposed at the front portion of the vehicle body,
is disposed in an upper portion of the rearview mirror, and
is able to irradiate areas forward of the vehicle.

2. The saddle riding vehicle according to claim 1 , comprising:
another lighting apparatus including an electric bulb or an LED as a light source.

3. The saddle riding vehicle according to claim 1 , comprising:
a camera unit that senses a situation ahead of the vehicle during nighttime traveling.

4. The saddle riding vehicle according to claim 3 , wherein the camera unit is capable of magnifying images.

5. The saddle riding vehicle according to claim 3 , wherein the camera unit detects visible light.

6. The saddle riding vehicle according to claim 3 , wherein the camera unit is disposed in a front cowl or a front cover.

7. The saddle riding vehicle according to claim 3 , wherein the camera unit is disposed in the rearview mirror.

8. The saddle riding vehicle according to claim 3 , wherein
an illumination direction of the light emitting unit can be changed toward a traveling direction of the vehicle that is estimated using at least a detection signal of a bank angle of the vehicle body, and
a lens of the camera unit can be directed toward the illumination direction.
