Description

LED photoelectric hollow glass

Technical Field

The utility model belongs to the technical field of LED photoelectric display glass, and particularly relates to LED photoelectric hollow glass.

Background

The multimedia display screens applied to the outdoor curtain wall at present are mainly divided into two types, wherein one type is a liquid crystal display wall formed by traditional LED non-transparent display spliced screens; the other type is LED photoelectric glass, and the LED photoelectric glass is a novel display technology which combines LED light-emitting lamp beads and transparent glass together.

The LED photoelectric glass comprises a light-emitting component and two outer-layer glasses, the light-emitting component comprises substrate glass and LED light-emitting lamp beads arranged on the substrate glass, the substrate glass is formed by splicing a plurality of pieces of glass, and the light-emitting component is pasted between the two outer-layer glasses through a rubber sheet. The LED photoelectric glass is applied to an outdoor building curtain wall and often influenced by external force such as wind power and the like, especially under the condition of large wind load, because the two outer layers of glass and the light-emitting component are bonded into a whole through the adhesive film, when the outer layer of glass of the LED photoelectric glass is stressed by wind pressure and the like and is subjected to deflection deformation, the light-emitting component can also generate deflection deformation along with the outer layer of glass, and therefore the substrate glass formed by splicing in the light-emitting component can be extruded at the splicing seam due to deflection deformation and possibly be damaged. The existing solution is to increase the overall strength and rigidity of the outer glass by thickening the outer glass to reduce the requirement of deflection deformation and avoid the substrate glass from cracking due to excessive deflection deformation.

However, due to the limitation of the substrate glass processing technology at present, the existing substrate glass can only be 3mm thick, and the thickness of the interlayer glass is not more than 3mm as specified in the building specification, so the thickness of the outer layer glass cannot exceed 6 mm. Therefore, under the condition of large wind load, the deflection resistance of the LED photoelectric glass cannot be improved by continuously thickening the outer layer glass; moreover, if the thickness of the outer layer glass is made larger, the weight of the outer layer glass is larger, the film clamping piece can be heated under the long-term light emitting effect of the LED light emitting lamp beads, the viscosity is reduced, the stable adhesion of the two outer layer glasses cannot be met, the safety performance cannot be guaranteed, the film clamping piece can generate a film separating phenomenon when being used between the two outer layer glasses for a long time, the glass and the glass are easily separated and fall off, and the potential safety hazard is brought. Meanwhile, heat generated by the light emitting component of the existing LED photoelectric glass can be conducted indoors through the outer glass, so that the indoor temperature is increased, and the energy-saving effect of a building is influenced.
