Abstract
A vehicle headlight (), which is one aspect of a vehicle illumination lamp, includes: light sources (R,G,B), and diffraction gratings (R,G,B) for diffracting light incident from the light sources (R,G,B). The light diffracted by the diffraction gratings (R,G,B) is irradiated in a predetermined light distribution pattern. A projection area (AR) to which are projected components (LC, LC, LC) advancing and passing through the diffraction gratings (R,G,B) among the light incident on the diffraction gratings (R,G,B) is positioned below the light distribution pattern and within a range (RNG) in which a field of view of a driver of a vehicle is obstructed by the vehicle.
