VEHICLE LIGHTING FIXTURE

摘要

A vehicle lighting fixture can eliminate the use of a phosphor member that causes the reduced color rendering properties and the occurrence of color separation, specifically, can enhance the color rendering properties and suppress the occurrence of color separation more than a conventional white light source that use a semiconductor light emitting element such as an LD and a phosphor member (wavelength converting member). The vehicle lighting fixture includes: a supercontinuum light source configured to output supercontinuum light containing light in a visible wavelength region, and an optical system configured to control the supercontinuum light output from the supercontinuum light source.

1. A vehicle lighting fixture comprising:
a supercontinuum light source having any of a pulse laser light source and a continuous wave (CW) laser light source, and a nonlinear optical medium configured to convert corresponding one of pulse laser light output from the pulse laser light source and continuous wave laser light output from the continuous wave laser light source into supercontinuum light for output, the supercontinuum light source having a directivity characteristic narrower than Lambertian light; and an optical system configured to control light emitted from the supercontinuum light source to form a predetermined light distribution pattern for a vehicle, wherein the light controlled by the optical system mainly contains coherent light.
