Description

Technical Field

[0001] This utility model relates to the field of lighting technology, specifically to a bread lamp with a quick-release structure. Background Technology

[0002] Bread lamps, widely used in homes, offices, and some industrial settings, are favored for their simple appearance and soft light. However, with the increasing prevalence of LED lighting technology, the core component of bread lamps—the lamp panel (integrating the light source and driver module)—has become a vulnerable part, leading to a significant increase in replacement and maintenance frequency. This has also highlighted structural design flaws in existing products.

[0003] Currently available bread-shaped lights present numerous inconveniences in terms of disassembly, assembly, and maintenance. Most products employ a fully bolted or simple snap-fit ​​connection structure, requiring a significant amount of time for disassembly alone. This is especially challenging for single-person installations, particularly in high-altitude settings. The snaps often rely on material deformation for engagement, concentrating stress at the base, which can lead to fatigue damage over time. Furthermore, repeated disassembly and assembly can cause the snaps to loosen, posing a safety hazard. Utility Model Content

[0004] To address the aforementioned problems, this utility model discloses a bread lamp with a quick-release structure.

[0005] The technical solution of this utility model is: a bread lamp with a quick-release structure, including a lamp holder connected to the wall by a first fastening bolt, a lamp plate installed in the lamp holder, and a bread lamp cover connected to the bottom of the lamp holder; The lamp holder sidewall is provided with an upper annular connecting plate, and the lamp holder sidewall located at the lower end of the upper annular connecting plate is provided with a lower annular connecting plate. The inner wall of the lower annular connecting plate is provided with several through notches along the circumference. The upper end of the lower annular connecting plate is provided with a locking post between two adjacent through notches. The bottom end of the upper annular connecting plate is provided with several limiting posts that are staggered with each of the locking posts. The bread lampshade and the lamp holder are connected by an H-shaped annular connecting strip, and the upper and lower ends of the annular connecting strip are respectively connected to the bread lampshade and the lamp holder by several second fastening bolts. The outer wall of the lamp panel is provided with snap-fit ​​blocks that correspond one-to-one with the through notch and match its shape. The snap-fit ​​blocks are provided with insertion interfaces that match the size of the snap-fit ​​posts.

[0006] Furthermore, the upper and lower ends of the annular connecting strip are respectively provided with several magnetic pieces, and the upper end surface of the bread lamp cover and the lower end surface of the lamp holder are both provided with annular metal pieces.

[0007] Note: When the lamp holder and the bread-shaped lampshade are connected to the ring-shaped connecting strip, the magnetic sheet attracts the ring-shaped metal sheet on the lamp holder and the bread-shaped lampshade, making the connecting surfaces fit tightly, effectively reducing loosening caused by vibration, and also simplifying the installation and disassembly steps.

[0008] Furthermore, the upper and lower ends of the vertical section of the annular connecting strip are respectively provided with a number of spherical blocks, and the outer walls of the bread lampshade and the lamp holder are provided with a number of limiting grooves that match the spherical blocks.

[0009] Note: When the sidewalls of the bread lampshade and the lamp holder come into contact with the vertical section of the annular connecting strip, a mechanical limit is formed between the spherical block and the limiting groove, which can further improve the tightness of the connection between the lamp holder and the bread lampshade and the annular connecting strip.

[0010] Furthermore, the spherical block is made of nylon, and the inner wall of the limiting groove is provided with a wear-resistant fiber layer, which is made of aramid fiber.

[0011] Note: The nylon spherical block can effectively resist wear during long-term use, preventing the limit failure caused by wear of the spherical block. The wear-resistant fiber layer is not only wear-resistant, but also enhances the structural strength of the inner wall of the limit groove, further ensuring the stability of the limit structure.

[0012] Furthermore, the lamp holder sidewall is uniformly provided with several heat dissipation fins along the circumference, the spacing between two adjacent heat dissipation fins is 3-5mm, and the inner wall of the bread lamp cover is provided with an anti-glare coating.

[0013] Explanation: The heat dissipation fins on the side wall of the lamp holder can quickly conduct the heat generated by the lamp panel during operation, and accelerate heat dissipation by increasing the contact area with the air, thus ensuring the lifespan of the lamp panel; the spacing design between the two heat dissipation fins can ensure the heat dissipation area while avoiding airflow obstruction caused by excessively dense heat dissipation fins, ensuring stable heat dissipation efficiency; the anti-glare coating on the inner wall of the bread lamp cover can soften the light emitted by the lamp panel, reduce glare caused by direct strong light, and reduce the stimulation of light on the human eye.

[0014] The beneficial effects of this utility model are: This utility model's bread-shaped light fixture with a quick-release structure employs a triple-fit structure of notch alignment, rotation snap-fit, and column limiting. The light panel can be installed with just three actions: pushing, rotating, and loosening. A single person can easily replace the light panel, significantly reducing maintenance difficulty. The disassembly process is the reverse of installation: loosen the second fastening bolt to remove the light cover, lift the light panel upwards to separate the snap-fit ​​blocks from the snap-fit ​​columns, and rotate the light panel clockwise or counterclockwise until the snap-fit ​​blocks on the outer wall of the light panel align with the through-notches of the lower annular connecting plate. Finally, remove the light panel. The disassembly and assembly process requires no specialized tools, and the operation logic is simple and easy to understand, improving maintenance convenience. The light panel is axially limited by the upper and lower annular connecting plates, and the annular connecting strip forms radial positioning with the lamp holder and lamp cover. This multi-fit structure ensures the lamp remains stable even under frequent handling or vibration environments. Attached Figure Description

Detailed Implementation

[0017] Example 1: As Figure 1 , 4 As shown in Figure 5, a bread lamp with a quick-release structure includes a lamp holder 1 connected to the wall by a first fastening bolt 4, a lamp plate 2 installed in the lamp holder 1, and a bread lamp shade 3 connected to the bottom end of the lamp holder 1. The first fastening bolt 4 adopts existing technology, such as a cross-slot pan head screw. The lamp holder 1 has an upper annular connecting plate 10 on its side wall and a lower annular connecting plate 11 on its side wall at the lower end of the upper annular connecting plate 10. The inner wall of the lower annular connecting plate 11 has four through-holes 110 along the circumference. The upper end of the lower annular connecting plate 11 has a locking post 111 between two adjacent through-holes 110. The bottom end of the upper annular connecting plate 10 has four limiting posts 100 that are staggered with each locking post 111. like Figure 2 As shown, the light bulb lampshade 3 and the lamp holder 1 are connected by an H-shaped annular connecting strip 30. The upper and lower ends of the annular connecting strip 30 are respectively connected to the light bulb lampshade 3 and the lamp holder 1 by several second fastening bolts 300. The second fastening bolts 300 adopt existing technology, such as cross-head pan head screws. The outer wall of the lamp panel 2 is provided with snap-fit ​​blocks 20 that correspond one-to-one with the through notch 110 and match the shape. The snap-fit ​​blocks 20 are provided with insertion interfaces 21 that match the size of the snap-fit ​​posts 111. The upper and lower ends of the annular connecting strip 30 are respectively provided with four magnetic pieces 31. The upper end of the bread lamp cover 3 and the lower end of the lamp holder 1 are provided with annular metal pieces 32. When the lamp holder 1 and the bread lamp cover 3 are connected to the annular connecting strip 30, the magnetic pieces 31 attract the annular metal pieces 32 on the lamp holder 1 and the bread lamp cover 3, so that the connecting surfaces fit tightly, effectively reducing loosening caused by vibration. At the same time, it also simplifies the installation and disassembly steps. The magnetic pieces 31 and the annular metal pieces are both made of existing technology. For example, the magnetic pieces made of existing neodymium iron boron strong magnetic material can be used. The annular metal pieces 32 can be made of permalloy or 430 stainless steel. like Figure 3 As shown, 20 spherical blocks 33 are provided at the upper and lower ends of the vertical section of the annular connecting strip 30, and 20 limiting grooves 34 matching the spherical blocks 33 are provided on the outer walls of the bread lamp cover 3 and the lamp holder 1. When the side walls of the bread lamp cover 3 and the lamp holder 1 come into contact with the vertical section of the annular connecting strip 30, mechanical limiting is formed between the spherical blocks 33 and the limiting grooves 34, which can further improve the tightness of the connection between the lamp holder 1 and the bread lamp cover 3 and the annular connecting strip 30. The spherical block 33 is made of nylon, and the inner wall of the limiting groove 34 is provided with a wear-resistant fiber layer 340. The wear-resistant fiber layer 340 is made of aramid fiber. The nylon spherical block 33 can effectively resist wear during long-term use and avoid limiting failure due to wear of the spherical block 33. The wear-resistant fiber layer 340 is not only wear-resistant, but also enhances the structural strength of the inner wall of the limiting groove 34, further ensuring the stability of the limiting structure. The lamp holder 1 has 20 heat dissipation fins 12 evenly arranged along the circumference of the side wall, with a spacing of 3mm between two adjacent heat dissipation fins 12. The inner wall of the bread lamp cover 3 is provided with an anti-glare coating 35. The heat dissipation fins 12 on the side wall of the lamp holder 1 can quickly conduct the heat generated by the lamp panel 2 during operation and accelerate heat dissipation by increasing the contact area with air, thus ensuring the service life of the lamp panel 2. The spacing design between two heat dissipation fins 12 can ensure the heat dissipation area while avoiding airflow obstruction caused by the heat dissipation fins 12 being too dense, thus ensuring stable heat dissipation efficiency. The anti-glare coating 35 on the inner wall of the bread lamp cover 3 can soften the light emitted by the lamp panel 2, reduce the glare caused by direct strong light, and reduce the stimulation of light on the human eye. The anti-glare coating is made of acrylic resin or microstructured silicon dioxide.

Use the first fastening bolt 4 to pass through the reserved hole on the edge of the lamp holder 1 to firmly connect the lamp holder 1 to the wall; S2. Align the snap-fit ​​blocks 20 on the outer wall of the lamp panel 2 with the through-holes 110 of the lower annular connecting plate 11. Then, push the lamp panel 2 upward so that the snap-fit ​​blocks 20 pass completely through the through-holes 110. Rotate the lamp panel 2 clockwise or counterclockwise until the snap-fit ​​blocks 20 are blocked by the limiting post 100. At this time, the insertion interface 21 on the snap-fit ​​block 20 is aligned with the snap-fit ​​post 111 of the lower annular connecting plate 11. Release the lamp panel 2 and let it fall. The insertion interface 21 on the snap-fit ​​block 20 snaps into the corresponding snap-fit ​​post 111, thus completing the installation of the lamp panel 2. S3. Pick up the H-shaped annular connecting strip 30, align its upper end with the lower end of the lamp holder 1, and attach the magnetic piece 31 at the upper end of the annular connecting strip 30 to the annular metal piece 32 at the lower end of the lamp holder 1. Use the second fastening bolt 300 to pass through the reserved hole at the upper end of the annular connecting strip 30 to further fix it to the lamp holder 1. S4. Pick up the bread lamp cover 3 and align its upper end with the lower end of the annular connecting strip 30. The annular metal piece 32 at the upper end of the bread lamp cover 3 and the magnetic piece 31 at the lower end of the annular connecting strip 30 will adhere to each other.
