LIGHT CONTROL MEMBER, AND LIGHT CONTROL DEVICE
To provide a light control member and a light control device that can expand the dynamic range of transmittance and have a fast speed of response to a change in transmittance.SOLUTION: A light control device 1 comprises: a photochromic layer 11 in which its transmittance is reduced upon receiving ultraviolet light and increased upon receiving visible light; a first shield layer 12 that is arranged to face a first surface of the photochromic layer 11 and blocks transmission of at least part of the ultraviolet light; a second shield layer 13 that is arranged on a second surface of the photochromic layer 11 and blocks transmission of at least part of the ultraviolet light; a light guide layer 14 that is arranged between the first shield layer 12 and the second shield layer 13, and guides light incident from ends 10a and 10b and emits at least part of the light toward the photochromic layer 11; an ultraviolet light source 20 that irradiates the end 10a of the light guide layer 14 with ultraviolet light; and a visible light source 30 that irradiates the end 10b of the light guide layer 14 with visible light.SELECTED DRAWING: Figure 2
【課題】透過率のダイナミックレンジを広くでき、かつ、透過率変化の応答速度の速い調光部材、調光装置を提供する。【解決手段】調光装置１は、紫外光を受光すると透過率が低下し、可視光を受光すると透過率が上昇するフォトクロミック層１１と、フォトクロミック層１１の第１面側に配置され、紫外光の少なくとも一部の透過を遮蔽する第１遮蔽層１２と、フォトクロミック層１１の第２面側に配置され、紫外光の少なくとも一部の透過を遮蔽する第２遮蔽層１３と、第１遮蔽層１２と第２遮蔽層１３との間に配置され、端部１０ａ、１０ｂから入射する光を導光して少なくとも一部の光をフォトクロミック層１１側へ出射する導光層１４と、導光層１４の端部１０ａへ紫外光を照射する紫外光光源２０と、導光層１４の端部１０ｂへ可視光を照射する可視光光源３０とを備える。【選択図】図２
