Japanese Patent JP2016058165
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a luminaire capable of controlling a travelling direction of high output light from a light source device stably with high accuracy.SOLUTION: A luminaire 40 includes: an optical element 50; and an irradiation device 60 for irradiating the optical element with light so as to scan on the optical element. The irradiation device includes: a light source device 61 for emitting light; and a scanner 70 having a reflection member 79 including a reflection surface 79a for reflecting the light from the light source device. The reflection member can rotate around a rotation axis Ra1 tilting with respect to a normal direction nd1 of the reflection surface. The light source device has: a plurality of light sources 62a-62g; optical fibers 64a-64g provided corresponding to each of the light sources respectively; and collimator lenses 67a-67g provided corresponding to each of the optical fibers respectively.SELECTED DRAWING: Figure 1
