    • A three-dimensional light reflection plate that can successfully prevent deformation of the light reflection plate, reduce initial cost and product cost, and facilitate increase in size and reflectance. The light reflection plate includes a bottom plate in which a plurality of mutually parallel slit holes are formed on a flat, light-reflective plate material and a mountain plate that is rectangular from a planar view of which a width direction cross-sectional shape is a mountain shape and in which insertion sections are formed in both width-direction end sections. The mountain plate is fixed to the bottom plate by the insertion sections of the mountain plate being inserted into the slit holes of the bottom plate.
    • 可以成功防止光反射板变形的三维光反射板,降低初始成本和产品成本,有利于尺寸和反射率的增加。 光反射板包括底板,其中在平坦的光反射板材上形成有多个相互平行的狭缝孔,并且从宽度方向横截面形状为 山形,并且在两个宽度方向端部形成有插入部。 山板被插入底板的狭缝孔中的山板插入部固定在底板上。
