摘要:
PROBLEM TO BE SOLVED: To provide a lighting device which suitably lights a whole desired area by performing a two-dimensional scanning with a collimated single light. SOLUTION: This lighting device 1 lights the whole desired area by performing the two-dimensional scanning with the collimated light beam and has a light source 2 which generates the collimated light 5, a micromirror 3 which generates a linear scanning trace by performing the scanning with the collimated light 5 and resonates and swings on one axis, and a rotary polygon mirror 4 having reflecting mirrors 4a which are long along the axis of rotation to perform the scanning with the linear scanning trace in a desired direction; and the micromirror 3 and the axis of rotation of the rotary polygon mirror 4 are arranged orthogonanlly to each other.
