Abstract

A vehicle lighting unit (1) that utilizes a semiconductor laser light source (11) can suppress the color unevenness of the light distribution pattern while ensuring the usefulness of the semiconductor laser light source (11). The vehicle lighting unit (1) can include a semiconductor laser light source (11), a phosphor (14) configured to receive blue light emitted from the semiconductor laser light source (11) and emit white light by excitation, and a reflector (15) configured to reflect the light emitted from the phosphor (14) so that the light can be diffused wider in a right-to-left direction than in a vertical direction on the basis of a posture where the lighting unit (1) is mounted on a vehicle body. Part of the blue light that is emitted from the semiconductor laser light source (11) and regularly reflected off a surface of the phosphor (14) can be incident on the reflector (15) with an elongated area in the right-to-left direction.
