Abstract
A lighting device for a vehicle includes an optical fiber having a light emitting end. A reflecting plate extends frontward of the light emitting end of the optical fiber, and separates a region frontward of the light emitting end of the optical fiber into first and second sub regions. The reflecting plate serves to reflect a portion of light emitted from the light emitting end of the optical fiber. An optical member is located at one of the first and second sub regions. The optical member is separate from the light emitting end of the optical fiber. The optical member serves to act on light emitted from the light emitting end of the optical fiber and light reflected by the reflecting plate.
Claims10
A lighting device for a vehicle, comprising:
- an optical fiber having a light emitting end;
- a reflecting plate extending from said light emitting end of said optical fiber and separating a region forward of said light emitting end of said optical fiber into first and second sub regions, said reflecting plate being constructed and arranged to reflect a portion of light emitted from said light emitting end of said optical fiber;
- and
- a first optical member located in said first sub region and being spaced away from said light emitting end of said optical fiber, said first optical member acting on light emitted from the light emitting end of the optical fiber and light reflected by the reflecting plate, wherein said first optical member is constructed and arranged to form a hot illuminated zone having a first brightness;
- and
- a second optical member located in said second sub region and acting on light emitted from said light emitting end of said optical fiber into said second sub region, wherein said second optical member is constructed and arranged to form an elongate illuminated zone having a second brightness lower than said first brightness.
A lighting device for a vehicle, comprising:
- an optical fiber having a light emitting end;
- a reflecting plate extending from said light emitting end of said optical fiber and separating a region forward of said light emitting end of said optical fiber into first and second sub regions, said reflecting plate being constructed and arranged to reflect a portion of light emitted from said light emitting end of the optical fiber;
- and
- an optical member located in one of said first and second sub regions and being spaced away from said light emitting end of said optical fiber, said optical member acting on light emitted from said light emitting end of said optical fiber and light reflected by said reflecting plate;
- wherein said optical member has an incident surface which faces said light emitting end of said optical fiber, and said reflecting plate oriented such that a portion of light emitted from said light emitting end of said optical fiber is reflected by said reflecting plate and is then incident on said incident surface of said optical member, while another portion of light emitted from said light emitting end of said optical fiber is directly incident on said incident surface.
