摘要:
A vehicle headlamp is provided including a road surface pattern-rendering unit and a dust removal device. The road surface pattern-rendering unit is installed to a headlamp unit provided to a front end section of a vehicle, and forms a specific light distribution pattern by causing light shone from a light source to be reflected by a MEMS mirror toward a vehicle front side. The dust removal device is provided to the headlamp unit and removes dust adhering to the MEMS mirror.
