Embodiment 1
[0050] Such as figure 1 A composite light guide plate for LED panel lights is shown, which includes a light guide plate 1 and a diffusion film 2, such as figure 1 The upper surface of the light guide plate 1 is a light-emitting surface, and the lower surface is a reflective surface. The diffusion film 2 is arranged on the light-emitting surface side of the light guide plate 1, and the light-emitting surface of the light guide plate 1 is provided with several convex microstructures A4 and Several convex microstructures B5 of equal height, the highest point of the microstructure A4 is higher than the highest point of the microstructure B5, and the top of the microstructure A4 is closely attached to the colloidal layer 3 formed by the diffusion film 2 through the bonding glue .
[0051] Such as figure 2 As shown in the side view schematic diagram A, the cross-section of the microstructures A4 is trapezoidal, and the microstructures are arranged at equal intervals on the light-...
Embodiment 2
[0057] The difference between this embodiment and embodiment 1 is only the cross-sectional shape of the microstructure A4, and the rest are the same. Such as image 3 As shown in the schematic side view B, the cross section of the microstructure A4 in this embodiment is triangular.
[0058] This example is assembled through the following steps:
[0059] 1) Coat one side of the diffusion film 2 with an aminoacrylic resin, and use a baking device to bake at 60° C. for 1 hour to preliminarily cure the aminoacrylic resin to form a gel layer 3 with a certain thickness;
[0060] 2) Align the diffusion film 2 provided with the colloidal layer 3 on the light-emitting surface of the light guide plate 1, make the colloidal layer 3 and the microstructure A4 on the light-emitting surface of the light guide plate 1 bond, and use the forming and laminating pressure wheel to press film, so that the diffusion film 2 is closely attached to the microstructure A4 through the colloidal layer 3;...
Embodiment 3
[0063] The difference between this embodiment and embodiment 1 is only the cross-sectional shape of the microstructure A4, and the rest are the same. Such as Figure 4 As shown in the schematic side view C, the cross section of the microstructure A4 in this embodiment is formed by a combination of a semicircle and a trapezoid.
[0064] This example is assembled through the following steps:
[0065] 1) Coating polyethylene resin on one side of the diffusion film 2, using a baking device to bake at 80° C. for 0.5 h, so that the polyethylene resin is initially cured to form a gel layer 3 with a certain thickness;
[0066] 2) Align the diffusion film 2 provided with the colloidal layer 3 on the light-emitting surface of the light guide plate 1, make the colloidal layer 3 and the microstructure A4 on the light-emitting surface of the light guide plate 1 bond, and use the forming and laminating pressure wheel to press film, so that the diffusion film 2 is closely attached to the m...
