Abstract
A directional prism reflective plate includes a prism surface (11) and a smoothing plane (12). A plurality of prism bodies (111) are arranged on the prism surface (11). The prism bodies (111) are continuously arranged in continuous zigzag form, and symmetrically or asymmetrically arranged relative to the center plane. Respective cross-section triangles of the prism bodies (111) have same shape and area, the distances from the vertexes of the cross-section triangle to the smoothing plane (12) are gradually reduced, so as to reflect the sunlight entirely. It is also provide a planar lamp and a planar lamp fixture including the reflective plate.
Claims25
A light-reflecting plate with triangular micro-prisms having identical cross section, wherein a plurality of parallel strip-like micro prism bodies are arranged along the left and right sides starting from the plane of the symmetrical center on the prism surface of the light-reflecting plate, the cross section of each micro prism body is triangle and the micro prism bodies are continuously arranged in zigzag form, characterized in that the triangles have the same shape and the same cross sectional area;
- the left and right apexes of the triangle adjacent to the symmetric center plane have the shortest distance away from another surface which is called the smooth surface of the light-reflecting plate, and the apices of the triangles towards the periphery of the light-reflecting plate have the successively increasing distances away from the smooth surface of the light-reflecting plate;
- the connection lines among the apices of the triangles of the circular prism bodies are two inclined straight lines, intersecting at a point with the central axial line of the light-reflecting plate and forming an inclusion angle α with the smooth surface of the plate, wherein the inclusion angle α is less than 45° and the distance of all triangles is equal in the length direction.
