When the bonding and laying area of ​​the entire homogenizing film is not large enough, multiple pieces can be spliced ​​and used, and two adjacent homogenizing films can be bonded to each other through the connecting wings. Specifically, the connecting wings at the bottom of the two adjacent homogenizing films are torn off, and the connecting wings are bonded to the homogenizing films again, that is, a part of the connecting wing is located at the bottom of the adhesive layer, and the other part of the connecting wing is bonded to the adhesive layer at the bottom of another adjacent homogenizing film, so that the multiple homogenizing films can be connected to each other to form an integral structure.

[0028] An adhesive uniform light film, such as Figure 1 and Figure 2 As shown, including:

[0029] The Fresnel layer 11 has a sheet-like structure and lenses for light uniformity are evenly distributed on the surface;

[0030] The transparent substrate layer 12 is bonded and fixed to the bottom surface of the Fresnel layer 11 and is a thin film structure for light transmission;

[0031] The prism layer 13 is bonded and fixed to the bottom surface of the transparent substrate layer 12 for refraction;

[0032] The adhesive layer 14 is bonded and fixed to the bottom surface of the prism layer 13 and is used for pasting equipment. Specifically, the light-homogenizing film is formed by bonding the Fresnel layer 11, the transparent substrate layer 12, the prism layer 13 and the adhesive layer 14 in sequence from top to bottom, wherein the adhesive layer 14 is the light incident surface, the Fresnel layer 11 is the light emitting surface, the bottom surface of the prism layer 13 is a plane, and a plurality of triangular prism-shaped protrusions are fixed on the top surface of the prism layer 13 to form a refractive surface. The transparent substrate layer 12 is made of PC material or PTE material, and the adhesive layer 14 can be formed by coating, and the specific material types are not restricted too much here.

[0033] like Figure 2 , Figure 3 and Figure 4 As shown, the connecting structure is arranged at the bottom of the adhesive layer 14 and is used for splicing two adjacent adhesive layers 14. The connecting structure includes a connecting side wing 20 and a bottom groove 22. The bottom groove 22 is opened at the bottom of the adhesive layer 14. The connecting side wing 20 is bonded and fixed in the bottom groove 22. Two sets of connecting structures are symmetrically arranged on the bottom surface of the adhesive layer 14. The two bottom grooves 22 can be bonded and fixed to each other. Two bottom grooves 22 are symmetrically arranged on the bottom surface of the adhesive layer 14. The top surface of the adhesive layer 14 located at the bottom groove 22 is coated with glue. The connecting side wing 20 is bonded to the adhesive layer 14 by glue. The bottom groove 22 is formed into a groove with the same width as the adhesive layer 14. The horizontal cross-sectional shape of the connecting side wing 20 is the same as the horizontal cross-sectional shape of the bottom groove 22. In this scheme, by setting the connecting side wing 20 and bonding and fixing it in the bottom groove 22, when the bonding and laying area of ​​the entire uniform light film is not large enough, Multiple pieces 10 are spliced ​​for use, and two adjacent homogenizing films can be bonded to each other through the connecting wing 20. Specifically, the connecting wing 20 at the bottom of the two adjacent homogenizing films is torn off, and the connecting wing 20 is bonded to the homogenizing film again, that is, a part of the connecting wing 20 is located at the bottom of the adhesive layer 14, and the other part of the connecting wing 20 is bonded to the adhesive layer 14 at the bottom of another adjacent homogenizing film, so that multiple homogenizing films can be connected to each other to form an integral structure. When multiple homogenizing films are pasted together for use, the integrity is stronger, and the warping of the contact position of the two adjacent homogenizing films is suppressed. By setting the adhesive layer 14, the homogenizing film can be pasted for use, and there is no need to apply adhesive during installation, which is convenient for construction. In order to ensure that the adhesive layer 14 does not adhere to foreign debris before construction, a base paper should also be bonded to the bottom of the adhesive layer 14 to ensure the viscosity of the adhesive layer 14, which will not be elaborated here.

[0034] like Figure 4 As shown, the connection structure also includes a notch 21. The notch 21 is opened at the bottom of the connecting wing 20. The notch 21 is a semicircular notch. By setting the notch 21, a semicircular notch is formed at the bottom of the connecting wing 20, which is convenient for tearing the connecting wing 20 from the bottom groove 22, thereby facilitating construction.

[0035] As not shown in the figure, the side wing 20 is folded to form a double-layer structure. The top and bottom surfaces of the folded connecting side wing 20 are coated with glue. The top surface of the folded connecting side wing 20 is bonded to the inner top surface of the glue layer 14, and the overlapping surfaces of the folded position of the connecting side wing 20 are also coated with glue and bonded to each other. The thickness of the connecting side wing 20 is less than the depth of the bottom groove 22. The two layers of the folded connecting side wing 20 are equal in height to the bottom groove 22. By folding the connecting side wing 20 in double layers, when bonding two adjacent homogenizing films, the bottom layer of the connecting side wing 20 at the bottom of one of the homogenizing films can be torn off, and the bottom layer of the connecting side wing 20 at the bottom of the other adjacent homogenizing film can be torn off. The two connecting side wings 20 can be bonded to each other after being unfolded, thereby forming a side wing for bonding two homogenizing films. The two unfolded connecting side wings 20 are bonded to the same height as the bottom groove 22, so that no bumps are formed at the joint after the two homogenizing films are connected, thereby ensuring the flatness after construction.

[0036] The specific shape of the lens is not shown in the figure. The lens is a Fresnel lens. Several groups of lenses are arranged on the top surface of the Fresnel layer 11. The Fresnel lenses in the same group are distributed in an array. Several Fresnel structures are evenly opened on the wall surface of the lens away from the Fresnel layer 11. The Fresnel structure is formed by multiple concentric circular grooves with decreasing depth, which will not be elaborated here.

[0037] The working principle of the utility model is as follows: when bonding two adjacent homogenizing films, the bottom layer of the connecting wing 20 at the bottom of one of the homogenizing films can be torn off, and the bottom layer of the connecting wing 20 at the bottom of the other adjacent homogenizing film can be torn off. The two connecting wing 20 can be bonded to each other after being unfolded, thereby forming a wing for bonding the two homogenizing films. The two unfolded connecting wing 20 are at the same height as the bottom groove 22 after bonding, thereby preventing the formation of bumps and depressions at the joints of the two homogenizing films after they are connected. Multiple homogenizing films are connected end to end to form a whole for homogenizing the surface of the equipment.

[0038] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model.
