Document Type and Number:
Japanese Patent JP6659392
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an illumination device which has a high resolution and can obtain a sufficient light flux quantity, and of which downsizing can be achieved.SOLUTION: An illumination device comprises: a light source part (2A) having plural light emission points; a light emission part (6) including a fluorescent body which emits light by receiving an excitation light; an excitation light scanning part (4) which adjusts an incident position of the excitation light with respect to the light emission part (6) so that a spot of the excitation light incident to the light emission part (6) is scanned on the light emission part (6); and a projector (7) which projects light emitted from the light emission part (6) onto a desired shape. There are plural sports, and each spot is derived from the excitation light outgoing from each light emission point. The excitation light scanning part (4) is so configured that respective spots are so scanned as to be not overlapped at a same time.SELECTED DRAWING: Figure 1
