A light-emitting sign for a vehicle includes: a container body defining a cavity; comprising at least one illumination source, the at least one illumination source being at least partially housed in the cavity and configured to emit at least one light beam; an inner lens for at least partially covering the illumination source includes a first transparent layer and a second diffusive or opalescent layer, the first transparent layer and the second diffusive or opalescent layer being integral with each other. The container body comprises: at least one projection at least partially passing through the cavity and abutting against a fixed portion of the inner lens, the projection forming a laser welded joint with the fixed portion, the fixed portion being in contact with the first transparent layer or the second diffusion or opalescence layer; and an outer lens superimposed to at least partially cover the inner lens and at least partially enclose the cavity, including an inner surface facing a second diffusive or opalescent layer of the inner lens. The inner surface is metallized and / or opaque to the light beam of the at least one illumination source and has at least one path or transparent image of the light beam.

The present application relates to the technical field of building ceramics, and discloses a zircon white fused block and a preparation method and application thereof, wherein, according to weight parts, the raw materials of the zircon white fused block include kaolin 12-20 parts, zirconium silicate powder 8-15 parts, quartz 30-42 parts, zinc oxide 3-8 parts, calcium phosphate salt 3-8 parts and fluxing components 20-42 parts. The zircon white fused block is rich in a large amount of microcrystalline zirconium oxide, and the zircon white fused block has excellent chemical temperature resistance and a refractive index significantly higher than that of a glass phase, so that a strong reflection and scattering effect is formed in a glaze surface; by introducing the zircon white fused block with high whiteness and high opalescence into a glaze system, the whiteness and opalescence of the fired glaze surface can be more effectively improved.
