  • Publication number: 20210116630
    Abstract: A light-guide sunroof assembly comprises a plastic substrate and a light source module furnished besides the plastic substrate. An outer layer of the plastic substrate is added with dye to form a colored background. A plurality of light-guide microstructures is furnished on the plastic substrate to guide the light generated by the light source module toward an inner surface of the plastic substrate. Thereby, the light generated by the light source module is guided by the plastic substrate and then ejects out of the inner surface of plastic substrate, so as to provide a light decoration or lighting effect that enriches the visual experience. Moreover, the plastic substrate is first formed into a curved plastic plate through a hot pressing process, and then a connecting structure is formed and fixed on the plastic plate by an insert-molding injection process, in order to replace the traditional car sunroof mechanism which is assembled by glass plate bonded with metal connecting parts.
