Title:
VEHICLE LIGHTING FIXTURE
Document Type and Number:
WIPO Patent Application WO/2020/179352
Kind Code:
A1
Abstract:
A vehicle lighting fixture (10) is provided with: a semiconductor laser element (32) which emits laser light; a wavelength conversion layer (34) which absorbs at least part of the laser light and emits wavelength converted light; and a projection lens (28) which captures and emits the wavelength converted light forward. The wavelength conversion layer (34) is arranged to face the projection lens (28). The semiconductor laser element (32) is arranged such that, assuming that the wavelength conversion layer (34) did not exist, light rays of the laser light lie outside the area of a capturing angle θ of the projection lens (28).
