Abstract
A first inclined surface and a second inclined surface are inclined with respect to an optical axis of a light emitting diode. The first inclined surface guides light from the light emitting diode guided in the first light transmitting portion toward an outside of an outer lens. An inclination angle of the second inclined surface with respect to the optical axis is larger than an inclination angle of the first inclined surface with respect to the optical axis. The second inclined surface reflects the light from the light emitting diode guided in the first light transmitting portion toward the second light transmitting portion and guides the light into the second light transmitting portion.
Claims18
A lighting device for a straddled vehicle, comprising:
- a housing;
- a single light emitting diode;
- and
- an outer lens attached to the housing, extending in a direction perpendicular to an optical axis of the light emitting diode, and having translucency;
- wherein
- the outer lens includes
- a first light transmitting portion overlapping the light emitting diode in an optical axis direction of the light emitting diode, and
- a second light transmitting portion disposed at a non-overlapping position with the light emitting diode in the optical axis direction,
- the first light transmitting portion and the second light transmitting portion are integrally formed,
- the second light transmitting portion is longer than the first light transmitting portion in a longitudinal direction of the outer lens,
- the first light transmitting portion includes
- a first inclined surface provided on an outer surface of the first light transmitting portion and inclined with respect to the optical axis of the light emitting diode, and
- a second inclined surface provided on the outer surface of the first light transmitting portion and inclined with respect to the optical axis of the light emitting diode,
- the first inclined surface guides light from the light emitting diode guided in the first light transmitting portion toward an outside of the outer lens,
- an inclination angle of the second inclined surface with respect to the optical axis is larger than an inclination angle of the first inclined surface with respect to the optical axis, and
- the second inclined surface reflects the light from the light emitting diode guided in the first light transmitting portion toward the second light transmitting portion, and guides the light into the second light transmitting portion, and
- a length of the second inclined surface along an inclined direction of the second inclined surface is greater than a length of the first inclined surface along an inclined direction of the first inclined surface.
