Description

Technical Field

[0001] This utility model relates to the field of lighting technology, specifically to a lighting fixture that facilitates the replacement of LED light source substrates. Background Technology

[0002] In the lighting field, LED lamps have been widely used due to their advantages such as energy saving and long lifespan. As the core component of LED lamps, the LED light source substrate carries light-emitting elements such as LED chips, and its performance and maintainability directly affect the lamp's performance and lifespan.

[0003] Traditional LED light source substrates are usually glued to the upper lampshade. When it is necessary to replace the light source substrate, the adhesiveness can make disassembly difficult and may damage the lampshade and the light source substrate. Therefore, a lamp with easy replacement of LED light source substrate is proposed to improve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a lamp that facilitates the replacement of LED light source substrates. By setting up quick-release components, it solves the problem that traditional LED light source substrates are usually glued to the upper lamp cover. When it is necessary to replace the light source substrate, the adhesiveness of the glue makes disassembly difficult and may damage the lamp cover and the light source substrate.

[0005] This utility model is achieved through the following technical solution:

[0006] This utility model is a lamp that facilitates the replacement of LED light source substrates. It includes a light source substrate, an upper lamp cover, and a quick-release assembly. The quick-release assembly is used to connect the light source substrate and the upper lamp cover. The quick-release assembly includes a connecting plate and two springs. The connecting plate is installed on the light source substrate and has two limiting grooves. The springs are set on the upper lamp cover and have a limiting bead installed at one end. The limiting bead cooperates with the connecting plate and the limiting grooves.

[0007] Furthermore, the quick-release assembly also includes a base plate, which is mounted on the upper lamp cover. Two mounting plates are mounted on the base plate, and each mounting plate has a groove on its facing surface. The other end of the spring is mounted on the groove.

[0008] Furthermore, the limiting bead slides into the groove, with the outer wall of the limiting bead abutting against the inner wall of the groove.

[0009] Furthermore, a lower lamp cover is provided on the upper lamp cover, and the upper and lower lamp covers are connected by a quick-release assembly, with the lower lamp cover being a transparent cover.

[0010] Furthermore, a connecting groove is provided on the upper lampshade, the base plate is installed on the connecting groove, the connecting plate is installed on the lower lampshade, and the bottom of the lower lampshade abuts against the bottom of the upper lampshade.

[0011] This utility model has the following beneficial effects:

[0012] This invention features a quick-release assembly. By applying a certain external force to the light source substrate, the limiting bead overcomes the spring force and slides out of the limiting groove, thereby separating the light source substrate from the upper lamp cover. This facilitates the replacement of the light source substrate and solves the problem that traditional LED light source substrates are usually glued to the upper lamp cover, making disassembly difficult due to the adhesive properties when the light source substrate needs to be replaced, and potentially damaging the lamp cover and the light source substrate.

[0013] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0020] 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.

[0021] Please see Figure 1-5This utility model provides a technical solution: a lamp that facilitates the replacement of LED light source substrates, including a light source substrate 1, an upper lamp cover 2, and a quick-release assembly 3. The quick-release assembly 3 is used to connect the light source substrate 1 and the upper lamp cover 2. LED beads are installed on the light source substrate 1, and a transformer is installed inside the upper lamp cover 2 by bolts. Multiple light source substrates 1 are connected by wires, and the transformer and the light source substrate 1 are connected by plugs and sockets. Generally, matching plugs and sockets are pre-installed at the output end of the transformer and the input end of the light source substrate 1. This is prior art and will not be described in detail here.

[0022] The quick-release assembly 3 includes a connecting plate 301 and two springs 303. The connecting plate 301 is fixedly installed on the light source substrate 1. Two limiting grooves 302 are opened on the connecting plate 301. The springs 303 are set on the upper lamp cover 2. A limiting bead 304 is fixedly installed on one end of the spring 303. The limiting bead 304 cooperates with the connecting plate 301 and the limiting groove 302.

[0023] The quick-release assembly 3 also includes a base plate 305, which is bolted to the upper lamp cover 2. Two mounting plates 306 are fixedly installed on the base plate 305. Sliding grooves 307 are provided on the facing surfaces of the two mounting plates 306. The other end of the spring 303 is fixedly installed on the sliding grooves 307.

[0024] The limiting bead 304 slides in conjunction with the slide groove 307. The outer wall of the limiting bead 304 abuts against the inner wall of the slide groove 307. The slide groove 307 can make the sliding of the limiting bead 304 more stable and prevent the limiting bead 304 from deviating during the sliding process.

[0025] When it is necessary to install the light source substrate 1 onto the upper lampshade 2, first, the connecting plate 301 on the light source substrate 1 is brought into contact with the two limiting beads 304. The connecting plate 301 is pushed forcefully until the two limiting beads 304 are squeezed by the connecting plate 301, and the spring 303 is compressed. The spring 303 drives the limiting beads 304 to slide into the slide groove 307. Then, the connecting plate 301 is pushed further until the connecting plate 301 drives the two limiting grooves 302 to engage with the two limiting beads 304 respectively. At the same time, the spring 303 restores its elastic deformation, and the two limiting beads 304 are respectively inserted into the two limiting grooves 302. This completes the installation of the light source substrate 1 and the upper lamp cover 2. When it is necessary to remove the light source substrate 1 from the upper lamp cover 2, a certain external force is applied to the light source substrate 1, so that the limiting bead 304 overcomes the elastic force of the spring 303 and slides out from the limiting groove 302, thereby separating the light source substrate 1 from the upper lamp cover 2, which facilitates the replacement of the light source substrate 1. This solves the problem that the traditional light source substrate 1 is usually glued to the upper lamp cover 2, and when it is necessary to replace the light source substrate 1, it is easy to make disassembly difficult due to the stickiness of the glue, and may damage the upper lamp cover 2 and the light source substrate 1.

[0026] The upper lamp cover 2 is provided with a lower lamp cover 4. The upper lamp cover 2 and the lower lamp cover 4 are connected by a quick-release assembly 3. The lower lamp cover 4 is a transparent cover. The upper lamp cover 2 has a connecting groove 201. The base plate 305 is installed on the connecting groove 201 by bolts. The connecting plate 301 is installed on the lower lamp cover 4 by bolts. The lower lamp cover 4 abuts against the bottom of the upper lamp cover 2. The upper lamp cover 2 and the lower lamp cover 4 are also connected by a quick-release assembly 3, which facilitates the cleaning or maintenance of the lamp cover. This solves the problem that the traditional lower lamp cover 4 is installed on the upper lamp cover 2 by bolts, and bolt installation requires the use of tools to tighten or loosen the bolts one by one, which is cumbersome and time-consuming.

These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification.
