The invention relates to a light-proof and light-tight automobile light-emitting exterior trimming part which comprises a transparent material, a first PVD metal plating layer and a second PVD metal plating layer, the first PVD metal plating layer and the second PVD metal plating layer are sequentially arranged on the back face of the transparent material, and a first protective layer is arrangedbetween the first PVD metal plating layer and the second PVD metal plating layer. And the first PVD metal plating layer, the first protective layer and the second PVD metal plating layer are removed according to patterns to form a light-transmitting region. The light-proof and light-tight automobile light-emitting exterior trimming part has the advantages that the selection range of the coating material is enlarged, the purpose of light tightness is achieved, light leakage is eliminated, the process difficulty is reduced, the plating layer thickness is reduced, and the cost is reduced.

    本发明涉及一种不透光且不漏光的汽车发光外饰件,包括透明素材、第一PVD金属镀层和第二PVD金属镀层,所述的透明素材背面依次设置有第一PVD金属镀层和第二PVD金属镀层,第一PVD金属镀层和第二PVD金属镀层之间设置有第一保护层,第一PVD金属镀层、第一保护层和第二PVD金属镀层按图形去除,形成透光区域。本发明具有加大镀层材料的选择范围、实现不透光的目的、消除漏光、降低工艺难度、降低镀层厚度、降低成本等优点。
