Description

Technical Field

[0001] This utility model relates to the field of lighting technology, specifically to a light-shielding tape used in lighting fixtures. Background Technology

[0002] Lighting fixtures are widely used in home, commercial, and industrial lighting scenarios. These fixtures mainly include chandeliers, spotlights, panel lights, and LED strips. LED strips are primarily used for ambient lighting, hence they are also known as LED ambient lights. They are a perfect choice for theme parks, hotels, homes, exhibitions, commercial spaces, and artistic lighting, creating the atmosphere people desire. People can set their preferred scene lighting effects according to their own lighting needs (such as color, temperature, brightness, and direction), and select and control the brightness, grayscale, and color changes of light in different spaces and at different times, based on their individual requirements and scene conditions.

[0003] To avoid excessive light dispersion, automotive LED ambient lights typically use opaque light-blocking tape to partially block the light, allowing the light to shine through the parts not covered by the tape. However, this method produces glaring, less soft light and a poor sense of atmosphere. Utility Model Content

[0004] In view of the shortcomings of the existing technology, this utility model provides a light-shielding tape for use in lamps, which effectively improves the softness of the light emitted by ambient lights, avoids the glare from the ambient lights, and enhances the atmosphere.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a light-shielding tape for use in lighting fixtures, comprising a transparent PET layer, a first adhesive layer, a second adhesive layer, an ink layer, and a matte film layer; the ink layer and the second adhesive layer are respectively coated on both sides of the transparent PET layer, and the matte film layer is adhered to the surface of the ink layer away from the transparent PET layer by the first adhesive layer; the light transmittance of the light-shielding tape is 50%-90%; by setting the matte film layer and controlling the light transmittance of the light-shielding tape to 50%-90%, the softness of the light emitted by the ambient light is effectively improved, solving the problems of glaring, insufficiently soft, and poor atmosphere caused by the light emitted by the ambient light.

[0006] Preferably, the light transmittance of the light-shielding tape is 60%-80%.

[0007] Preferably, the combined thickness of the matte film layer, the transparent PET layer, the ink layer, and the first adhesive layer is 25-50 μm.

[0008] Preferably, the combined thickness of the matte film layer, the transparent PET layer, the ink layer, the first adhesive layer, and the second adhesive layer is 60-90 μm.

[0009] Preferably, a release film is provided on the surface of the second adhesive layer away from the transparent PET layer.

[0010] Preferably, the combined thickness of the matte film layer, the transparent PET layer, the ink layer, the first adhesive layer, the second adhesive layer, and the release film is 85-120 μm.

[0011] Beneficial effects

[0012] This utility model provides a light-shielding tape for use in lighting fixtures. Compared with the prior art, it has the following advantages:

[0013] Beneficial effects:

[0014] 1. By setting a matte film layer and controlling the light transmittance of the light-shielding tape to 50%-90%, the softness of the light emitted by the ambient light is effectively improved, making the light less dazzling and enhancing the atmosphere.

[0015] 2. By controlling the light transmittance of the light-shielding tape to 50%-90%, compared with the existing methods of using light-shielding tape, the entire surface of the LED ambient light can be covered with light-shielding tape, eliminating the need to leave unshielded areas for light to shine out. This ensures that the overall color of the LED ambient light remains consistent, and the LED ambient light with the light-shielding tape already applied can be better concealed during installation, improving the aesthetics of the installation.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-2This utility model provides a technical solution: a light-shielding tape for use in lighting fixtures. The light-shielding tape 1 includes a transparent PET layer 14, a first adhesive layer 12, a second adhesive layer 15, an ink layer 13, and a matte film layer 11. The ink layer 13 and the second adhesive layer 15 are respectively coated on both sides of the transparent PET layer 14. The matte film layer 11 is adhered to the surface of the ink layer 13 away from the transparent PET layer 14 by the first adhesive layer 12. The light transmittance of the light-shielding tape 1 is 50%-90%. By setting the matte film layer 11 and controlling the light transmittance of the light-shielding tape 1 to 50%-90%, the softness of the light emitted by the ambient light is effectively improved, solving the problems of glaring, insufficiently soft, and poor atmosphere caused by the light emitted by the ambient light.

[0021] It should be understood that the second adhesive layer 15 may not be provided in this utility model, and other methods can be used to fix the light-shielding tape 1 to the surface of the lamp.

[0022] Furthermore, the light transmittance of the light-blocking tape 1 is 60%-80%.

[0023] Furthermore, the combined thickness of the matte film layer 11, the transparent PET layer 14, the ink layer 13, and the first adhesive layer 12 is 25-50 μm, preferably 43±0.5 μm.

[0024] Furthermore, the combined thickness of the matte film layer 11, the transparent PET layer 14, the ink layer 13, the first adhesive layer 12, and the second adhesive layer 15 is 60-90 μm, preferably 78 μm.

[0025] Furthermore, a release film 16 is provided on the surface of the second adhesive layer 15 away from the transparent PET layer 14.

[0026] It should be understood that in this utility model, a glue with a lower viscosity can also be used as the second adhesive layer 15, thereby eliminating the need for a release film 16.

[0027] Furthermore, the sum of the thicknesses of the matte film layer 11, the transparent PET layer 14, the ink layer 13, the first adhesive layer 12, the second adhesive layer 15, and the release film 16 is 85-120 μm, preferably 116 μm.

[0028] It should be understood that by setting a release film 16 with a larger thickness, it is easier to peel off the release film 16 more quickly during use, making the light-blocking tape 1 of this utility model more convenient to use.

[0029] It should be noted that the transparent PET layer 14 is a transparent PET film, also known as a high-temperature resistant polyester film. It has excellent physical properties, chemical properties, dimensional stability, transparency, and recyclability. It has good transparency and gloss; it has good airtightness, can achieve moisture protection, and its moisture permeability decreases at low temperatures.

[0030] The method of using this utility model is as follows: After treating the LED ambient light with traditional light-shielding tape, remove the release film 16 of the light-shielding tape 1 in this utility model, and then stick the light-shielding tape 1 of this utility model to the surface of the LED ambient light where it is not light-shielded through the second adhesive layer 15.

[0031] This invention effectively improves the softness of the ambient light emitted by the light source by setting a matte film layer 11 and controlling the light transmittance of the light-shielding tape 1 to 50%-90%, making the light less glaring and enhancing the atmosphere. Compared with existing methods of using light-shielding tape 1, by controlling the light transmittance of the light-shielding tape 1 to 50%-90%, the entire surface of the LED ambient light can be covered with light-shielding tape 1, eliminating the need to reserve an unshielded area for light to shine out, ensuring a consistent overall color for the LED ambient light. Furthermore, the LED ambient light with the light-shielding tape already applied can be better concealed during installation, improving the aesthetics of the installation.
