Patent ID: 6969183

Claim:
A digital lighting apparatus that illuminates a road surface with a predetermined light distribution pattern, comprising: an optical engine that includes a light source; a reflection type digital light deflector that has a plurality of micro mirror elements arranged to be respectively tiltable, that digitally switches a tilt angle of each of the micro mirror elements between a first tilt angle and a second tilt angle to switch a reflection direction of a light from the optical engine between a first reflection direction as an ON state and a second reflection direction as an OFF state; a light irradiation unit that irradiates an ON state light reflected from the reflection type digital light deflector on a road surface; a storage unit that stores digital data of a plurality of light distribution patterns; and a controller that selects a specific digital data corresponding to the predetermined light distribution pattern from among the digital data stored in the storage unit based on an input signal, and that digitally switches a tilt angle of each of the micro mirror elements based on the digital data selected.
