Abstract
(EN)
A composite membrane, comprising a base plate (100); the base plate is used for corresponding to a light source (10), and an emergent surface of the base plate is provided thereon with multiple dispersive prism areas (4) and multiple diffusion plates (5), wherein the dispersive prism areas correspond to lamp bead shadow areas (2), and the diffusion plates correspond to non-lamp bead shadow areas (3); the dispersive prism areas are provided in areas in which light energy is distributed unevenly, while only the diffusion plates are laid in areas in which light energy is distributed evenly, and the dispersive prisms need not be laid, thereby reducing production costs while improving the phenomenon of a visual effect being uneven. Further disclosed is a design method for a composite membrane.
(FR)
La présente invention porte sur une membrane composite comprenant une plaque de base (100). La plaque de base est destinée à correspondre à une source lumineuse (10) et présente sur une surface émergente de multiples zones de prisme dispersif (4) et de multiples plaques de diffusion (5), les zones de prisme dispersif correspondant à des zones d'ombre de perles de lampe (2), et les plaques de diffusion correspondant à des non-zones d'ombre de perles de lampe (3). Les zones de prisme dispersif sont situées dans des zones où l'énergie lumineuse est répartie de manière irrégulière tandis que seules les plaques de diffusion sont disposées dans des zones où l'énergie lumineuse est répartie de manière uniforme, les prismes dispersifs ne nécessitant pas d'être disposés, ce qui permet de réduire les coûts de production tout en améliorant le phénomène d'un effet visuel irrégulier. L'invention concerne en outre un procédé de conception d'une membrane composite.
