照明装置及び車両用灯具
Document Type and Number:
Japanese Patent JP7382242
Kind Code:
B2
Abstract:
A lighting device includes a laser light source (2) configured to emit a laser beam (BL), a wavelength conversion member (3) including a laser beam irradiation region (E) to which the laser beam (BL) is radiated and configured to emit a wavelength converted light excited by radiation of the laser beam (BL), a laser beam scanning mechanism (4) configured to form a light distribution pattern according to a scanning range (S) of the laser beam (BL) by scanning the laser beam (BL) radiated to the laser beam irradiation region (E), and a projection lens (200) configured to project illumination light that forms a light distribution pattern forward, and an incidence angle of the laser beam (BL), which is scanned by the laser beam scanning mechanism (4), with respect to the wavelength conversion member (3) is set to an angle where the laser beam (BL) does not directly enter the projection lens (200) when the wavelength conversion member (3) is damaged, chipped or fallen off.
