Abstract
A vehicle lamp () includes a light source () that emits pieces of laser light (LR, LG, LB) having different wavelengths in a time division manner, and a plurality of diffraction gratings (R,G,B) corresponding to the pieces of laser light (LR, LG, LB) of the wavelengths, respectively. The laser light (LR, LG, LB) of the wavelengths emitted from the light source () are incident on the diffraction gratings (R,G,B) corresponding to the laser light (LR, LG, LB), and regions irradiated with light (DLR, DLG, DLB) emitted from the diffraction grating (R,G,B) overlap with each other.
