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

[0037] The structure of the point-shaped building glass curtain wall projection imaging film of the present embodiment is as follows:

[0038] Please combine Figure 1-3 It should be understood that the point-shaped building glass curtain wall projection imaging film 1 of the present embodiment includes a diffuse reflection coating 11, a light-transmitting base film layer 12, a glue layer 13 and a bottom layer 14 bonded to each other in sequence. There are a plurality of reflective base units 120 arrayed on the film layer 12, and these reflective base units 120 can be covered on the light-transmitting base film layer 12 by printing, and the shape can be disc-shaped, and every two adjacent reflective base units The unit 120 has a separation area, and the area of ​​the light-transmitting base film layer 12 opposite to these separation areas is a light-transmission unit 121. It should be noted that each light-transmission unit 121 is connected to each other to form a whole area, ...

Embodiment 2～6

[0049] The dot-shaped architectural glass curtain wall projection imaging film of embodiments 2 to 6 has many similarities with the dot-shaped architectural glass curtain wall projection imaging film of embodiment 1, and these similarities will not be repeated. However, the differences from embodiment 1 Yes: the diameters of the reflective elements 120, the distance between two adjacent reflective elements 120 and / or the presence or absence of the diffuse reflection coating 11, please refer to Table 1 below for details.

[0050] Table 1 lists the specific parameters of the diameter / area of ​​these reflective elements 120 and the circle margins of two adjacent reflective elements 120 in the different types of point-shaped building glass curtain wall projection imaging films in Examples 1 to 6, And marked with or without diffuse reflection coating 11. Wherein, when the material of the light-transmitting base film layer of each projection imaging film is made of PET material, the...

Embodiment 7

[0062] The point-shaped building glass curtain wall projection imaging film of this embodiment has many similarities with the point-shaped building 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 point-shaped architectural glass curtain wall projection imaging film 3 of this embodiment and the point-shaped architectural glass curtain wall projection imaging film of Embodiment 1 is that there are a plurality of reflective elements arrayed on the light-transmitting base film layer. Some reflective primitives are not completely aligned in rows and columns, and reflective primitives in two adjacent rows are staggered from each other.

Abstract

The invention provides a dotted building glass curtain wall projection imaging film. The projection imaging film comprises a light-transmitting base film layer, wherein a plurality of reflecting elements are arrayed on the light-transmitting base film layer; the reflecting elements cover the light-transmitting base film layer; every two adjacent reflecting elements have a separated region; the regions of the light-transmitting base film layer opposite to the separated regions are light-transmitting elements. By using the projection imaging film of the structure, the light-transmitting elements can transmit light to keep normal illumination intensity in a building; the reflecting elements can reflect projection light, so that the projection quality of a building glass curtain wall is improved.

Description

technical field [0001] The invention relates to the field of projection imaging, in particular to a point-shaped building glass curtain wall projection imaging film. Background technique [0002] With the gradual acceleration of the urbanization process, 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 vie...
