Light guide, lighting device for a vehicle, and vehicle
ActiveCN224397642UImprove sophisticationIncrease the sense of designVehicle headlampsLighting and heating apparatusLight guideEngineering
The utility model discloses a light guide piece, lighting device and vehicle for vehicle, the utility model relates to light guide technical field, and light guide piece has the light inlet surface and the light outlet surface, and the light inlet surface is used to set up with light source piece to correspond to to make light source piece emit light enter light guide piece and emit from the light outlet surface, and light guide piece still has the side wall surface connected between the light inlet surface and the light outlet surface, and the side wall surface forms the recessed groove recessed to light guide piece. Through recessed groove recessed to light guide piece at the side wall surface of light guide piece, recessed groove recessed to light guide piece can make light occur diffuse reflection or scattering at recessed groove, to make light more evenly mix and spread in light guide piece inside, thereby can greatly reduce the risk that the local overbright of light outlet surface forms bright line, and recessed groove presents 3D effect that suspends in material under the condition of not destroying the permeability of light guide piece, and the delicate feeling and design sense of light guide piece are improved on the appearance.

A ceramic surface fiber composite layer and a preparation method and application thereof
PendingCN122541227Aretain high strengthEliminate the risk of migration
This invention relates to a ceramic surface fiber composite layer, its preparation method, and its application. The high-toughness fiber composite layer is attached to the surface of a ceramic blank. The fiber composite layer is composed of multiple interwoven mullite fibers and a silica sol solidified phase. The mullite fibers have an alumina content of 70wt%~80wt% and are short-cut fibers with a length of 3~10mm. The preparation process of the fiber composite layer is as follows: silica sol is sprayed onto the surface of the ceramic blank; mullite fibers are dispersed on the surface of the ceramic blank; the silica sol is dried to fix the mullite fibers to the surface of the blank; this step is repeated several times, and after completion, silica sol is sprayed again, and the fiber composite layer is prepared when the blank mass remains unchanged. Compared with existing technologies, the ceramic with a fiber composite layer prepared by this invention can be used as tableware and art pieces, possessing advantages such as high toughness, food safety, compatibility with the ceramic blank, and suitability for the low-temperature sintering process requirements of daily-use ceramics.
