Car window glass capable of emitting light

Abstract

The invention relates to the technical field of car window glass, in particular to car window glass capable of emitting light. The car window glass comprises a first transparent plate, a first transparent binding layer, a flexible transparent substrate, a second transparent binding layer and a second transparent plate which are sequentially stacked from top to bottom. The car window glass is characterized in that the second transparent binding layer and the second transparent plate are the same in refractive index, the refractive index of the second transparent binding layer is larger than that of the flexible transparent substrate, and a linear light source is arranged on the lateral edge of the second transparent plate; incident light of the linear light source is made to come in from the lateral edge of the second transparent plate and / or the lateral edge of the second transparent binding layer and to be guided and transmitted between the second transparent plate and the second transparent binding layer; and a scattering layer for scattering the incident light of the linear light source is arranged on the lower surface of the flexible transparent substrate. The car window glass has the advantages that the production process is simple, repeating precision is high, and product stability is good.

Description

Technical field: [0001] The invention relates to the technical field of vehicle window glass, in particular to a luminous vehicle window glass, which is especially suitable for vehicle skylights. Background technique: [0002] The luminous vehicle sunroof has a unique lighting and decorative effect, which makes the car compartment more gorgeous at night, can play a role in setting off the atmosphere and creating a mood in the car, and has been widely used in the technical field of vehicle sunroofs for mid-to-high-end models. A luminous vehicle sunroof commonly used in the prior art includes a window glass and a light-emitting element installed at the edge of the window glass. By setting a reflective element on the surface of the window glass, the effect of a planar light source is formed on the entire surface of the window glass. Homogeneous lighting in the window can thus be achieved. [0003] A vehicle glazing disclosed in Chinese patent CN103770696 includes a light sourc...

AI Technical Summary

Problems solved by technology

Since the light guide layer is mostly rigid curved glass, in the existing production process, the convex surface of the curved glass is the transmission surface, so the surface structure cannot be carried out before bending and forming, and the surface structure is formed on the curved surface. Accuracy and repeatability are difficult, product stability is poor, and it is difficult to achieve mass production
