[0044] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0045] Example 1:

[0046] Please see the attached Figures 1 to 4 The present invention provides a lamp body 100 comprising a lamp frame 1, an optical assembly 3, a base plate 2, and a light-emitting assembly 4 mounted within the lamp frame 1. The optical assembly 3 comprises a light-transmitting element 31 and a light-emitting element 32. The lamp body 100 utilizes a double-layer membrane structure formed by the light-transmitting element 31 and the light-emitting element 32 to achieve both mosquito repellent and noise reduction functions.

[0047] Specifically, Figure 2A cross-sectional view of the entire lamp body mechanism 100 of this embodiment is given. Figure 2 As shown, the lamp frame 1 has a first end 11 and a second end 12 opposite each other. A light emitting element 32 is disposed at the first end 11 of the lamp frame 1, and a base plate 2 is disposed at the second end 12 of the lamp frame 1. The light emitting element 32, the lamp frame 1, and the base plate 2 surround a housing cavity 5. The light-emitting component 4 is mounted on the base plate 2 and located within the housing cavity 5. A light-transmitting element 31 is connected to the inner sidewall of the lamp frame 1 and divides the housing cavity 5 into a first light-mixing cavity 51 and a second light-mixing cavity 52, which are not interconnected. Light emitted by the light-emitting component 4 passes through the first and second light-mixing cavities 51, 52, and then exits the light emitting element 32 to the outside. Because the light-transmitting element 31 separates the first light-mixing cavity 51 from the second light-mixing cavity 52, mosquitoes entering the first light-mixing cavity 51 through the bottom plate 2 are blocked from entering the second light-mixing cavity 52, preventing the light mixing effect in the second light-mixing cavity 52 from being affected. This also helps prevent shadows from appearing in the illumination of the lamp body 100 due to the presence of mosquitoes in the accommodating cavity 5, thereby ensuring the light output quality of the lamp body 100. Furthermore, the double-layer structure formed by the light-transmitting element 31 and the light-emitting element 32 can achieve a dual absorption effect on external sound passing through the lamp body 100, thereby achieving the effects of noise reduction and echo reduction.

[0048] The inner sidewall of the light frame 1 is provided with a first positioning portion 110 for connecting with the light-transmitting member 31. The first positioning portion 110 includes a first limiting body 111 extending from the inner sidewall of the light frame 1 toward the accommodating cavity 5, and a first limiting groove 112 defined in the first limiting body 111. The light-transmitting member 31 includes a light-transmitting portion 311 and a first fixing portion 312 disposed around the outer periphery of the light-transmitting portion 311. The first fixing portion 312 can be secured to the first limiting groove 112 by locking or snapping, thereby separating the light-mixing cavity into a first light-mixing cavity 51 and a second light-mixing cavity 52 that are not connected to each other, while maintaining the light-transmitting function of the light-transmitting portion 311.

[0049] In this embodiment, the optical assembly 3, base plate 2, and light-emitting assembly 4 are arranged in parallel. A first retaining groove 112 is formed by the first retaining body 111 being recessed in the direction from the first end 11 to the second end 12. A seal 6 is disposed within the first retaining groove 112, and the first fixing portion 312 is engaged within the first retaining groove 112 via the seal 6. The seal 6 separates the edge of the light-transmitting element 31 from the first light-mixing cavity 51, effectively preventing mosquitoes from entering the second light-mixing cavity 52 through the gap between the light-transmitting element 31 and the lamp frame 1. Therefore, the seal 6 not only secures the light-transmitting element 31 but also enhances the seal between the light-transmitting element 31 and the lamp frame 1.

[0050] In addition, to ensure that the lighting effect is not affected by the arrangement of the light-transmitting member 31 and mosquitoes, the distance between the light-transmitting member 31 and the light-emitting member 32, that is, the height of the second light-mixing cavity 52, is preferably greater than or equal to 30 mm. This ensures that the second light-mixing cavity 52 mixes the light sufficiently, ensuring that the light output effect of the lamp body mechanism 100 is not affected by the presence of mosquitoes.

[0051] To further enhance the mosquito-proofing effect, the structure between the light emitting member 32 and the light frame 1 can be optimized to prevent mosquitoes from entering the accommodating cavity 5 through the gap between the light emitting member 32 and the light frame 1. For example, the light frame 1 also includes a second positioning portion 120 extending toward the accommodating cavity 5. The light emitting member 32 includes a light emitting portion 321 and a second fixing portion 322 disposed around the outer periphery of the light emitting portion 321. The second fixing portion 322 is configured to connect with the second positioning portion 120 to securely attach the light emitting member 32 to the light frame 1. The second positioning portion 120 is provided with a second retaining groove 122, into which the light emitting member 32 is secured by locking or snapping.

[0052] In this embodiment, similar to the fixation between the first positioning portion 110 and the light-transmitting member 31, a sealing member 6 is provided within the second limiting groove 122 for securing the light-emitting member 32 within the second limiting groove 122. The sealing member 6 secures the light-emitting member 32 and simultaneously seals the light-emitting member 32 and the lamp frame 1. The light-emitting portion 321 has a light-emitting surface that is flush with or recessed relative to the plane of the first end 11 of the lamp frame 1.

[0053] It should be noted that the above description does not constitute the sole limitation on the mounting structure of the light-emitting element 32 and the light-transmitting element 31. In some embodiments, the first positioning portion 110 may also be a first abutment surface extending from the inside of the lamp frame 1 toward the accommodating cavity 5, with the first abutment surface being parallel to the light-emitting surface. The first fixing portion 312 of the light-transmitting element 31 covers and closely adheres to the first abutment surface. The first abutment surface isolates the edge of the light-transmitting element 31 from the first light-mixing cavity 51, thereby preventing mosquitoes from entering the second light-mixing cavity 52.

[0054] Similarly, the second positioning portion 120 can be a second abutment surface extending from the inner side of the light frame 1 toward the accommodating cavity 5. The second fixing portion 322 of the light output member 32 is in close contact with the second abutment surface, and the second abutment surface forms a tight structure between the edge of the light output member 32 and the light frame 1, thereby preventing mosquitoes from entering the light frame 1 through the first end 11.

[0055] In some embodiments, the connection structure between the base plate 2 and the light frame 1 can also be optimized, so that the base plate 2 and the light frame 1 are tightly connected to further prevent mosquitoes from entering through the gap between the base plate 2 and the light frame 1. For example, a third positioning portion 13 extending toward the accommodating cavity 5 is provided on the inner side of the second end 12 of the light frame 1. In this embodiment, the third positioning portion 13 is provided with a third abutting surface parallel to the optical component 3. The base plate 2 is located above the third abutting surface, and the edge is in close contact with the third abutting surface to ensure that the third abutting surface blocks the edge of the base plate 2, thereby preventing mosquitoes from entering the accommodating cavity 5 through the gap between the third positioning portion 130 and the base plate 2.

[0056] Furthermore, to enhance the noise reduction effect of the lamp body 100, the light-transmitting element 31 and the light-emitting element 32 are made of materials with excellent sound absorption properties. In this embodiment, the light-transmitting element 31 is a transparent PVC film, and the light-emitting element 32 is a PVC diffusion film. When external sound enters the lamp body 100 through the first end 11, it passes through the light-emitting element 32 and the light-transmitting element 31 in sequence. The sound is absorbed and processed by the double-layer membrane structure of the light-emitting element 32 and the light-transmitting element 31, ultimately achieving a noise reduction effect of over 20%.

[0057] Example 2:

[0058] The difference between this embodiment and embodiment 1 is that this embodiment further optimizes the structure of the lamp body mechanism 100 of the present invention. For the similarities, please refer to embodiment 1. The optimization is further described below.

[0059] In order to ensure the light mixing effect, the size of the light-transmitting portion 311 of the light-transmitting member 31 is greater than or equal to the size of the light-emitting surface of the light-emitting component 4. Figure 5 The light-emitting assembly 4 includes multiple light strips 41 attached to the base plate 2. These light strips 41 surround a light-emitting area 42. To maximize the efficiency of the light-emitting assembly 4, the area of ​​the light-transmitting portion 311 of the light-transmitting member 31 is preferably larger than or equal to the area of ​​the light-emitting area 41 to prevent the light-transmitting member 31 from blocking the light emitted by the light-emitting assembly 4.

[0060] In addition, the first positioning portion 110 is connected to the lamp frame 1 and is located outside the light-emitting area 41 to prevent the first positioning portion 110 from blocking the light emitted by the light-emitting component 4, thereby ensuring that most of the light mixed by the first light-mixing cavity 51 can pass through the light-transmitting member 31 and enter the second light-mixing cavity 52, so as to avoid affecting the lighting effect due to the protrusion of the first positioning portion 110.

[0061] Example 3:

[0062] This embodiment provides a lighting device based on Embodiment 2. The lighting device can be a flat panel light, a light box, etc. For similarities, please refer to Embodiment 2 and its related drawings.

[0063] In this embodiment, the lighting device is a light box. It includes a lamp body 100. Specifically, the lamp body 100 comprises a lamp frame 1, an optical assembly 3 mounted within the lamp frame 1, a base plate 2, and a light-emitting assembly 4. The optical assembly 3 comprises a light-transmitting element 31 and a light-emitting element 32. The double-layer membrane structure formed by the light-transmitting element 31 and the light-emitting element 32, in conjunction with the lamp frame 1, achieves both mosquito repellent and noise reduction functions.

[0064] The lamp frame 1 is provided with a first end 11 and a second end 12. The light emitting member 32 is provided at the first end 11 of the lamp frame 1, and the base plate 2 is provided at the second end 12 of the lamp frame 1. The light emitting member 32, the lamp frame 1 and the base plate 2 are surrounded by a receiving cavity 5, and the light emitting component 4 is mounted on the base plate 2 and is located inside the receiving cavity 5. The light-transmitting member 31 is connected to the inner wall of the lamp frame 1, and divides the receiving cavity 5 into a first light-mixing cavity 51 and a second light-mixing cavity 52 that are not connected to each other. The light emitted by the light-emitting component 4 passes through the first light-mixing cavity 51 and the second light-mixing cavity 52 in sequence and then is emitted from the light emitting member 32 to the outside. Under the action of the light-transmitting member 31, mosquitoes entering the first light-mixing cavity 51 from the base plate 2 will be blocked outside the second light-mixing cavity 52, avoiding the presence of mosquitoes affecting the light mixing effect and causing shadows in the light output, thereby ensuring the light output quality of the lamp body mechanism 100. In addition, the double-layer structure formed by the light-transmitting member 31 and the light-emitting member 32 can achieve a double sound absorption effect, thereby achieving the effect of reducing noise and echo.

[0065] The above content is merely an example and illustration of the structure of the present invention. Although the description is relatively specific and detailed, it should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art may make various modifications and improvements without departing from the concept of the present invention, and these obvious alternative forms are all within the scope of protection of the present invention.
