Problems solved by technology

[0006] However, the above-mentioned reflective film also has the problem of poor light transmittance. When working in the daytime, because the light cannot enter the building through the reflective film, the illuminance inside the building is low, which affects normal office work and people's basic needs for sunlight.

Embodiment 1

[0038] The structure of the architectural glass curtain wall projection imaging film of the present embodiment is as follows:

[0039] Please combine Figure 1-3 It should be understood that the architectural glass curtain wall projection imaging film 1 of the present embodiment includes a diffuse reflection coating 11, a base film layer 12, an adhesive layer 13 and a bottom layer 14 bonded to each other in sequence, and the base film layer 12 is arrayed with A plurality of light through holes 120, these light through holes 120 are opened on the base film layer 12, and a plurality of reflective elements 121 are also arrayed on the base film layer 12, each light reflective element 121 is two adjacent In the interconnection area between the light holes 120 , the light holes 120 and the reflective elements 121 are spaced apart from each other.

[0040] The base film layer 12 can be made of polyethylene plastic (PE plastic for short), polyvinyl chloride plastic (PVC plastic for s...

Embodiment 2

[0063] The architectural glass curtain wall projection imaging film of this embodiment has many similarities with the architectural glass curtain wall projection imaging film of Embodiment 1, and these similarities will not be repeated. However, please combine Figure 6 It should be understood that the difference between the architectural glass curtain wall projection imaging film 3 of this embodiment and the architectural glass curtain wall projection imaging film of Embodiment 1 is that there are a plurality of light holes arrayed on the base film layer, and these light holes are not completely The rows and columns are aligned, and the light holes of two adjacent rows are staggered from each other.

Embodiment 3

[0065] The architectural glass curtain wall projection imaging film of this embodiment has many similarities with the architectural glass curtain wall projection imaging film of Embodiment 1, and these similarities will not be repeated. However, please combine Figure 7 It should be understood that the difference between the projection imaging film 4 of the architectural glass curtain wall of the present embodiment and the projection imaging film of the architectural glass curtain wall of Embodiment 1 is that the base film layer can be made into a black and white chessboard-style primitive shape, and these The light-transmitting element is a white light-transmitting part, and these reflective elements are silver-black reflective parts. At this time, the white light-transmitting part only needs to be light-transmitting and does not need punching at all.

Abstract

The invention provides a projection imaging film for a glass curtain wall of a building. The projection imaging film comprises a base film layer, wherein a plurality of light transmitting elements are arrayed on the base film layer, a plurality of reflecting elements are further arrayed on the base film layer, and the light transmitting elements and the reflecting elements are mutually spaced. The plurality of light transmitting elements and the plurality of reflecting elements are arrayed on the base film layer and mutually spaced, and light transmitting elements can transmit light to keep the normal illumination intensity inside the building; and the reflecting elements can reflect the projection light, so that the projection quality of the glass curtain wall of the building is improved.

Description

technical field [0001] The invention relates to the field of projection imaging, in particular to a projection imaging film for architectural glass curtain walls. Background technique [0002] With the gradual acceleration of urbanization, the number of buildings has increased dramatically year by year. At the same time, the number of floors of buildings is also increasing, and some giant buildings have become urban landmarks (city landmarks). With the development of urbanization, commercial media is also becoming more and more popular. It has become a popular fashion to use giant LED screens or LCD screens to project the latest fashion products or corporate logos. [0003] Under the influence of high-rise buildings and commercial media, people apply projection technology (such as 3D projection) to buildings to project various artistic shapes in order to form colorful media advertisements or light shows, thereby promoting and beautifying urban life . In view of the fact t...
