Description of the Drawings
[0015] Figure 1 It is a schematic structural diagram of a white oil film in the prior art.
[0016] Figure 2 It is a schematic structural diagram of a white oil film applied to a light-emitting module of the present utility model. Detailed Embodiments
[0017] The following will describe the embodiments of the present utility model in detail with reference to the drawings.
[0018] Please refer to Figure 2, A white oil adhesive film applied to a light-emitting module, including an adhesive film body 1. The adhesive film body 1 includes a first connecting film 11, a first adhesive layer 12 connected to one side of the first connecting film 11, a white oil layer 13 connected to one side of the first adhesive layer 12, and a second connecting film 14 connected to one side of the white oil layer 13. The first connecting film 11 is used to isolate dust to protect the viscosity of the first adhesive layer 12, and the second connecting film 14 is used to protect the white oil layer 13. Among them, the design of the first connecting film 11 can protect the viscosity of the first adhesive layer 12, ensure that the adhesive layer is not contaminated during storage and use, and maintain its good adhesion performance. The first adhesive layer 12, as a connecting layer, firmly adheres the white oil adhesive film to the light-emitting module or other substrates. The white oil layer 13 provides the performance of reflecting light for the light-emitting module. Further, the second connecting film 14 plays a role in protecting the white oil layer 13 from scratches, contamination and other damages during transportation, storage and use. Adopting such a design solves the problem that the white oil adhesive film made by the original method has a large thickness and cannot be effectively applied to thinner products, such as the backlight FPC flexible board of a notebook keyboard, and optimizes the production process of the white oil adhesive film, effectively reducing the production cost of the white oil adhesive film. At the same time, a second connecting film is added to protect the white oil layer, effectively preventing the white oil layer from being damaged during transportation and operation, avoiding affecting the performance of the white oil adhesive film, and thus effectively improving the quality of the white oil adhesive film.
[0019] Further, please refer to Figure 2 , A white oil adhesive film applied to a light-emitting module, wherein the first connecting film 11 is a release paper. The release paper can prevent the adhesive from adhering to it, so that the adhesive film can be easily peeled off from it without damaging the adhesive layer. When using the white oil adhesive film, tear off the release paper, and the white oil adhesive film can be attached to the predetermined position. No additional tools or complicated preparations are required, improving the convenience of using the white oil adhesive film, and effectively protecting the first adhesive layer 12 of the white oil adhesive film, avoiding contamination of the white oil adhesive film during production and transportation, resulting in a decrease in the viscosity of the first adhesive layer 12, and ensuring the adhesion performance of the first adhesive layer 12.
[0020] Further, please refer to Figure 2, A white oil adhesive film applied to a lighting module. The first adhesive layer 12 is an AD adhesive, and the first adhesive layer 12 adheres to the upper side of the first connection film 11. The AD adhesive has good initial adhesion, holding adhesion, and peel strength, which can meet the requirements for the white oil adhesive film to adhere to the lighting module. At the same time, the AD adhesive has heat resistance and good chemical stability. Therefore, the AD adhesive is used as the material of the first adhesive layer 12. At the same time, the first adhesive layer 12 adheres to the upper side of the first connection film 11. The role of the first connection film 11 is to protect the first adhesive layer 12 from contamination during transportation and production. When the white oil adhesive film is ready to be pasted onto the target surface, the first connection film 11 is torn off, and the AD adhesive of the first adhesive layer 12 adheres the white oil adhesive film to the target surface.
[0021] Further, please refer to Figure 2 , A white oil adhesive film applied to a lighting module. The white oil layer 13 is a white thermosetting ink, and the white oil layer 13 is located on the upper side of the first adhesive layer 12. The white thermosetting ink has good insulation performance and can effectively isolate the electricity of the lighting module. At the same time, the cured ink layer of the thermosetting ink can provide a certain mechanical strength so that the white oil adhesive film can withstand certain external impacts and vibrations. Further, the function of reflecting light of the white thermosetting ink is the core function of the white oil layer 13, which helps to improve the overall brightness and uniformity of the lighting module. Secondly, the thermosetting ink has thermal stability, and the thermosetting ink can also maintain its structure and performance at a certain high temperature. Therefore, the white oil adhesive film can remain stable under the heat emitted by the lighting module, effectively improving the service life of the white oil adhesive film. Further, the thermosetting ink has good processing adaptability, and the thermosetting ink can be applied by screen printing, inkjet printing, coating, etc. This provides a variety of process options for the manufacture of the white oil adhesive film, enabling more effective cost control and production efficiency improvement. In the structure where the white oil layer 13 is located on the upper side of the first adhesive layer 12, the white thermosetting ink is in direct contact with the first adhesive layer 12. Compared with the prior art, the step of laying a PI film on the adhesive layer is omitted, optimizing the structure and production process of the white oil adhesive film and reducing the production cost.
[0022] Further, please refer to Figure 2, A white oil adhesive film applied to a lighting module. The second connecting film 14 is a PET film, and the second connecting film 14 is located on the upper side of the white oil layer 13. The PET film has high tensile strength and toughness, which can effectively protect the white oil layer 13 and prevent the white oil adhesive film from being physically damaged during transportation and production. Further, the PET film has high transparency, which can allow light to pass through without affecting the reflection of light by the white oil layer 13. Moreover, the PET film has a lower cost compared to other high-performance thin film materials, which can effectively reduce the production cost of the white oil adhesive film. Since the second connecting film 13 is located on the upper side of the white oil layer 13, it not only protects the white oil layer 13 but also provides additional processing convenience during the final assembly process. In practical applications, the second connecting film 14 will be removed after the white oil adhesive film is completely fixed to expose the white oil layer 13 so that it can reflect the light emitted by the lighting module.
[0023] Further, please refer to Figure 2 , A white oil adhesive film applied to a lighting module. The adhesive film body 1 further includes a second adhesive layer 141 located on the lower surface of the second connecting film 14, and the second adhesive layer 141 is a low-adhesion adhesive. Using a low-adhesion adhesive as the material of the second adhesive layer 141 is mainly to enable the second connecting film 14 to be easily peeled off from the white oil layer 13 because the second connecting film 14 needs to be removed before the white oil adhesive film is officially used, and the low-adhesion adhesive layer ensures that this process is simple and does not damage the integrity and performance of the white oil layer 13. The second connecting film 14 is in contact with the white oil layer 13 through the second adhesive layer 141, which can effectively prevent the white oil layer 13 from being polluted by the external environment. The low-adhesion adhesive layer allows the operator to easily remove the second connecting film 14 by hand or tools without using additional solvents or tools, simplifying the operation process and effectively improving the production efficiency.
[0024] Further, please refer to Figure 2 , A white oil adhesive film applied to a lighting module. The thickness range of the first adhesive layer 12 is 2μm - 120μm. The thickness of the first adhesive layer 12 determines the pasting strength of the white oil adhesive film and the overall thickness of the white oil adhesive layer. A thicker adhesive layer can provide stronger bonding force, and the thickness of the first adhesive layer 12 can be adjusted according to different usage conditions to achieve the best usage effect.
[0025] Further, please refer to Figure 2, A white oil film applied to a light-emitting module, the thickness range of the white oil layer 13 is 1μm - 40μm. This thickness range of the white oil layer 13 is an interval that can achieve stable production with existing coating technologies and printing technologies. If it is too thin, coating or printing will be uneven. If it is too thick, internal stress or bubbles may be generated during curing, affecting product quality. Therefore, setting the thickness range of the white oil layer 13 at 1μm - 40μm is a relatively stable interval. Within the range of 1μm to 40μm, the most suitable thickness of the white oil layer 13 can be selected according to specific application requirements, such as space limitations, power of the light-emitting module, and cost control, etc.
[0026] Further, please refer to Figure 2 , A white oil film applied to a light-emitting module, the first adhesive layer 12 is fixedly connected to the white oil layer 13, and the first connecting film 11 is separably connected to the first adhesive layer 12. The fixed connection between the first adhesive layer 12 and the white oil layer 13 means that these two layers are permanently bonded together during the manufacturing process of the white oil film. This fixed connection ensures that during use and application, the first adhesive layer 12 and the white oil layer 13 will not separate, maintaining the structural integrity and functionality of the white oil film. The fixed connection between the first adhesive layer 12 and the white oil layer 13 is achieved by coating the white oil layer 13 on the surface of the first adhesive layer 12 and then through high-temperature curing and pressing. At the same time, the cured white oil layer 13 forms a firm interface to withstand mechanical stress and changes in environmental conditions, effectively improving the stability of the white oil film. Secondly, the separable connection between the first connecting film 11 and the first adhesive layer 12 means that the first connecting film 11 remains in contact with the first adhesive layer 12 during storage, transportation, and preliminary processing stages to protect the first adhesive layer 12 from contamination and damage. When the white oil film is applied to a light-emitting module, the first connecting film 11 can be easily peeled off manually or mechanically without causing damage or residue to the first adhesive layer 12, effectively improving production efficiency and ensuring the functionality and use convenience of the white oil film.
[0027] Further, please refer to Figure 2, A white oil adhesive film applied to a lighting module. The second adhesive layer 141 is fixedly connected to the second connecting film 14, and the second connecting film 14 is separably connected to the white oil layer 13. With such a design, it means that the second adhesive layer 141 is fixedly attached to the second connecting film 14. The design of the second adhesive layer 141 being a low-adhesion adhesive enables the second connecting film 14 to be temporarily attached to the white oil layer 13 to protect the white oil layer from damage during storage and transportation and prevent the intrusion of dust and other contaminants when the white oil adhesive film is applied to the lighting module. The second connecting film 14 can be easily removed without causing damage or residue to the white oil layer 13, ensuring the functionality of the white oil layer 13.
