Abstract:
This lighting device (40) comprises an optical element (50), and an irradiation device (60) for irradiating light onto the optical element in such a manner as to scan over the optical element. The irradiation device comprises a light source device (61) for emitting light, and a scanner (70) having a reflective member (79) containing a reflective surface (79a) for reflecting the light from the light source device. The reflective member is rotatable centered around a rotation axis line (Ra1), which is tilted with respect to the normal direction (nd1) of the reflective surface. The light source device comprises a plurality of light sources (62a to 62g), optical fibers (64a to 64g) provided to correspond to the light sources respectively, and collimating lenses (67a to 67g) provided to correspond to the optical fibers respectively.
