PROBLEM TO BE SOLVED: To provide a vehicular dimmer capable of limiting only light in a region irradiated with the light dazzling a driver's eyes.SOLUTION: A windshield 10 comprises an electronic control-type lighting control film. In each of a plurality of areas into which an area partitioned with the windshield 10 is divided, transmittance can be independently adjusted. A minimum area including an intersection point of the windshield 10 and a line connecting a driver's eye point P and a light source (the sun 40) dazzling his/her eyes is set as a specific area SA. Electronic control is performed to decrease the transmittance of the specific area SA.

    【課題】運転者が眩しいと感じる光の照射領域の光のみを制限することのできる車両用調光装置を提供する。【解決手段】フロントガラス10には、電子制御式の調光フィルムが備えられており、フロントガラス10によって区画される領域を複数に分割した領域のそれぞれについて、独立に透過率を調整可能となっている。運転者のアイポイントPと眩しいと感じられる光源(太陽40)とを結ぶ線とフロントガラス10との交点を包含する極力小さい領域を特定領域SAとし、特定領域SAの透過率を低下させるべく、電子制御がなされる。【選択図】図3
