Lighting unit

摘要

A lighting unit 1 can form a plurality of light distribution pattern without shielding light from a light source. The lighting unit 1 can include a laser diode 11, a fluorescent member 13 with a fluorescent portion 13 configured to receive blue light from the laser diode 11 and emit white light, and a projector type lens 15 configured to project the white light. The fluorescent member 13 can be rotated around a rotation shaft 16 perpendicular to the optical axis Ax of the projector type lens 15 and shaped such that when the fluorescent member 13 is rotated by a predetermined angle by the driving member 17 and viewed from the projector type lens 15, a plurality of contours of the fluorescent portion 13 can be changed according to the predetermined angle.
