Light and shadow changing decoration layer with conical structure

Abstract

The invention relates to light and shadow changing decoration layers with conical structures, and discloses a light and shadow changing decoration layer with a pyramid structure. The light and shadowchanging decoration layer with the pyramid structure comprises a transparent substrate branch-layer, an adhesive branch-layer, a texture branch-layer, a plating branch-layer and a coloring branch-layer which are sequentially arranged from top to bottom, wherein the texture branch-layer comprises a base sub-layer and a micro structure sub-layer, the base sub-layer is arranged between the adhesive branch-layer and the micro structure sub-layer, and the micro-structure sub-layer is formed by alternately arranging conical structure units; and the vertex angle range of each conical structure unit ranges from 90 degrees to 150 degrees, and the vertex angles of the conical structure units of the micro-structure sub-layer are gradually increased from the edge to the middle direction. The light andshadow changing decoration layer with the pyramid structure has the following beneficial effects that by means of reflection of light rays on the side face of the conical structure, the visual anglesof different angle ranges can be obtained by adjusting the radiation vertex angles of the conical structure, and as the angle is increased, the brightness visually presented is brighter and brighter.

Description

technical field [0001] The invention relates to a surface decoration material, in particular to a light and shadow changing decoration layer with a tapered structure. Background technique [0002] At present, with the improvement of people's requirements for the quality of life, people have higher and higher requirements for the appearance of electronic products. Electronic products include: mobile phones, tablets, computers, televisions, etc. Taking mobile phone cases as an example, mobile phone cases need to focus on two aspects: function and aesthetics. From a functional point of view, as the 5G era approaches, new functions such as wireless charging will be superimposed. Popularity, the signal shielding defect of the metal casing is obvious, and reform is urgently needed; from the aesthetic point of view, the homogeneity of the metal body design is serious. The use of non-metal body design can achieve differentiation effect, and the de-metallization of body design is th...
