PROBLEM TO BE SOLVED: To provide a lighting apparatus which visualizes light so as to be moved while avoiding enlargement of the lighting apparatus.SOLUTION: A lighting apparatus 1 includes: a light guiding body 10 constituted by arranging linear light guiding members for inducing light made incident from one end in the longitudinal direction to the other end side, side by side in a width direction of the light guiding members; light sources 20 which are prepared every light guiding members and apply light toward the corresponding light guiding members; and a control part 30 which controls turning-on/off of the respective light sources 20. The light guiding body 10 is composed of a first light guiding member 11 and a second light guiding member 12 which are adjacent to each other in the width direction, a brightness distribution in the longitudinal direction of illumination light emitted from the first light guiding member 11 is configured so as to get to darker as proceeding from one end 111 side to the other end 112 side, a brightness distribution in the longitudinal direction of illumination light emitted from the second light guiding member 12 is configured so as to get to brighter as proceeding from one end 121 side to the other end 122 side, and the control part 30 is configured such that a light source 20A of the first light guiding member 11 and a light source 20B of the second light guiding member 12 alternately are turned on.SELECTED DRAWING: Figure 1
【課題】照明装置の大型化を避けつつ、光が移動するように視認させる照明装置を提供する。【解決手段】長手方向の一端から入射した光を他端側に誘導する線状の導光部材を導光部材の幅方向に並べて構成した導光体10と導光部材毎に用意されて対応する導光部材に向けて光を照射する光源20と、光源20の各々の点灯/消灯を制御する制御部30とを有する照明装置1である。導光体10を、幅方向で隣接する第1導光部材11及び第2導光部材12から構成し、第1導光部材11から出射される照明光の長手方向での輝度分布を一端111側から他端112側に向かうにつれて暗くなるように構成し、第2導光部材12から出射される照明光の長手方向での輝度分布を一端121側から他端122側に向かうにつれて明るくなるように構成し、制御部30が第1導光部材11の光源20Aと第2導光部材12の光源20Bを交互に点灯させる構成とした。【選択図】図1
