Description

Technical Field

[0001] The utility model relates to the technical field of composite membranes, in particular to a high-performance multifunctional composite membrane. Background Art

[0002] "Glare" is an undesirable lighting phenomenon. When the brightness of the light source is extremely high or there is a large difference in brightness between the background and the center of the field of vision, "glare" will occur. The "glare" phenomenon not only affects viewing, but also affects vision health. LED lamps generally use diffusion films to correct the light diffusion angle, increase the light radiation area, and use anti-glare films to reduce the generation of glare.

[0003] After searching, the Chinese patent announcement number: CN209248061U discloses a multifunctional composite film. By adding an anti-glare layer, the anti-glare film with two anti-glare layers can achieve a balance between light efficiency and anti-glare. The reason is that the more anti-glare layers there are, the better the anti-glare effect is, but at the same time, the light efficiency is greatly reduced. The anti-glare film with two anti-glare layers can greatly improve the anti-glare effect while reducing the light efficiency less. Therefore, the UGR value of the lamp using this anti-glare film can be reduced to below 16.

[0004] The above composite film has certain defects in actual use. For example, the thickness of the composite film is increased compared with the single-layer film. For LED lamps with high heat dissipation requirements, the addition of the composite film will affect the heat dissipation performance of the lamp, resulting in overheating or performance degradation. Therefore, a high-performance multifunctional composite film is proposed to solve the above problems. Utility Model Content

[0005] In order to make up for the above deficiencies, the utility model provides a high-performance multifunctional composite film, which aims to improve the problem that the thickness of the composite film in the prior art is increased compared with the single-layer film. The addition of the composite film will affect the heat dissipation performance of the lamp, leading to overheating or performance degradation.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a high-performance multifunctional composite membrane, including a composite membrane main body, on which are opened vent hole 1, vent hole 2 and vent hole 3, wherein vent hole 1, vent hole 2 and vent hole 3 are each provided with multiple groups, and multiple groups of vent hole 1, vent hole 2 and vent hole 3 are arrayed and distributed on the composite membrane main body, and vent hole 1, vent hole 2 and vent hole 3 are interconnected.

[0007] As a further description of the above technical solution:

[0017] The utility model has the following beneficial effects:

[0018] 1. In the utility model, heat can flow through the surface and bottom of the composite membrane body through the vent hole 1, and the vent hole 2 and the vent hole 3 are located around the composite membrane body 1 to enhance the heat conduction and heat dissipation effect, which helps to conduct heat from LED lamps or other heat sources to the surrounding environment, thereby reducing the temperature of the equipment and improving its performance and reliability.

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] Reference Figure 1-4 The utility model provides an embodiment: a high-performance multifunctional composite membrane, including a composite membrane body 1, on which a vent hole 11, a vent hole 2 12 and a vent hole 3 13 are provided, and multiple groups of vent holes 11, vent holes 2 12 and vent holes 3 13 are arranged, and multiple groups of vent holes 11, vent holes 2 12 and vent holes 3 13 are arrayed on the composite membrane body 1, and the vent holes 11, vent holes 2 12 and vent holes 3 13 are interconnected. The vent hole 11 runs through the surface and bottom surface of the composite membrane body 1 so that heat can flow. The vent holes 2 12 and the vent holes 3 13 are located around the composite membrane body 1, which enhances the heat conduction and heat dissipation effect, and helps to conduct heat from LED lamps or other heat sources to the surrounding environment, thereby reducing the temperature of the equipment and improving its performance and reliability. Glass fiber tubes 14 are fixedly connected to the air holes 11, 12 and 13, and the multiple groups of glass fiber tubes 14 are interconnected. The glass fiber tubes 14 are used for heat transfer and can support the internal structures of the air holes 11, 12 and 13, so that the composite membrane body 1 has higher strength.

[0028] Reference Figure 1-3The surface of the composite membrane body 1 is fixedly connected with multiple groups of prisms 15 distributed in an array. The bottom surface of the composite membrane body 1 is provided with multiple groups of arc grooves 2 distributed in an array. The prisms 15 and the arc grooves 2 form a micron-level concave-convex structure on the surface of the composite membrane body 1, so that the light is reflected and refracted at different angles, thereby achieving a diffusion effect. The bottom surface of the composite membrane body 1 is fixedly connected with an adhesive film 3, which is arranged in multiple groups, and the multiple groups of adhesive films 3 are distributed at the intervals of the multiple groups of arc grooves 2. The arrangement of the adhesive film 3 can improve the adhesion performance of the composite membrane to other surfaces. The surface of the adhesive film 3 is provided with multiple groups of reserved holes 31 distributed in an array. The reserved holes 31 correspond to the positions of the vent holes 11. The reserved holes 31 make the adhesive film 3 have strong air permeability. The bottom surface of the adhesive film 3 is fixedly connected with a protective film 4. The protective film 4 provides protection for the adhesive film 3 before use to ensure the adhesion of the adhesive film 3 when it is used.

[0029] Working principle: The arrangement of vent 11, vent 2 12 and vent 3 13 on the composite membrane body 1 allows heat to circulate inside the membrane, and the distribution of vent 2 12 and vent 3 13 enhances the heat conduction and heat dissipation effect. The through-hole design of vent 11 enables heat to be conducted from the surface and bottom of the composite membrane, effectively reducing the temperature of LED lamps or other heat sources. The glass fiber tube 14 is not only used for heat transfer, but also supports the internal structure of the vent, improving the strength and stability of the composite membrane body 1. The prism mirror 15 fixedly connected on the surface and the arc groove 2 on the bottom form a micron-level concave-convex structure, which allows light to be reflected and refracted on the surface of the composite membrane, achieving the diffusion effect of light, thereby improving the utilization rate and uniformity of light. The arrangement of the adhesive film 3 improves the adhesion performance of the composite membrane to other surfaces, and the design of the reserved hole 31 enhances the air permeability of the adhesive film 3, making the overall structure more ventilated and breathable. The protective film 4 provides protection for the adhesive film 3 to ensure that it can maintain good adhesion before use.
