LIGHT REFLECTION PLATE AND LIGHT REFLECTION METHOD
PROBLEM TO BE SOLVED: To provide a light reflection plate when mounted on a tail lamp of a vehicle such that an inter-vehicle distance to a preceding vehicle is easily grasped by a crew member of a subsequent vehicle.SOLUTION: A light reflection plate 10 includes: an irregular reflection portion 20 and a mirror reflection portion 30 in an area where a light beam flux is projected. The irregular reflection portion 20 has an irregular reflection surface 21 that irregularly reflects the light beam flux. The mirror reflection portion 30 has a mirror reflection surface 31 of which a reflection surface faces upward to reflect the light beam flux upward.SELECTED DRAWING: Figure 1
【課題】車両のテールランプに搭載された場合において、後続車両の乗員に前方車両との車間距離を把握させ易くする。【解決手段】本発明に係る光反射板１０は、光線束が照射される領域に乱反射部２０及びミラー反射部３０を具備し、乱反射部２０は、光線束を乱反射する乱反射面２１を有し、ミラー反射部３０は、反射面を上方側に向け、光線束を上方側に向けて反射するミラー反射面３１を有して構成される。【選択図】 図１
