Description

Technical Field

[0001] This utility model relates to the technical field of lighting fixtures, specifically to an indoor LED bulb. Background Technology

[0002] In the field of household lighting, bulb lamps are one of the most common lighting fixtures. They can be used for both home lighting and outdoor quick-installation lighting. Due to their simple overall structure, easy installation, low replacement cost, low energy consumption, and long lifespan, they are accepted by consumers, especially by overseas users and small vendors. They are also one of the mainstream exported light bulbs.

[0003] A T-bulb, a type of bulb lamp, mainly consists of several components, including a lamp holder, lamp body, lamp cover, and LED light source board. The LED light source board is generally installed inside the lamp body, while the lamp holder is installed at the rear of the lamp body and connected to the LED light source board via two power cables. Although the current T-bulb technology is mature, research has found that the presence of the lamp body results in relatively high manufacturing costs and a large size. This makes it difficult for companies to further reduce transportation and sales costs when exporting. Therefore, a new T-bulb structure is needed to solve this problem. Summary of the Invention

[0004] In order to solve one or more technical problems existing in the prior art, the purpose of this application is to provide an indoor LED bulb that can solve the problems of large size and high cost of existing bulbs, with better heat dissipation and simpler structure.

[0005] To address the aforementioned technical problems, the objective of this application is achieved through the following technical solution: An indoor LED bulb, characterized in that it includes a lamp holder, a lampshade, an LED light source board, and a connector. The lampshade has a recessed mounting groove on the inner side of its open end. The LED light source board has a mounting hole in the middle. The bottom of the connector is engaged with the mounting hole. The mounting hole is located on the connector. The LED light source board is embedded in the mounting groove for fixation. The back of the LED light source board is exposed.

[0006] Preferably, the lampshade has a U-shaped cross-section, and the inner wall of the lampshade is provided with a plurality of outwardly protruding limiting ribs, the top of which is flush with the lower side of the mounting groove.

[0007] Preferably, the lampshade has a flared guide opening at its open end.

[0008] Preferably, the mounting hole has a square structure, and the corners of the mounting hole are rounded.

[0009] Preferably, the connecting seat includes a stop ring with a diameter larger than the mounting hole, a buckle protruding downward at the bottom of the stop ring, and a connecting ring on the stop ring, with the lamp head mounted on the connecting ring.

[0010] Preferably, four buckles are evenly arranged around the bottom of the stop ring, and the buckles are arc-shaped and engage at the corner of the mounting hole.

[0011] Preferably, the bottom of the stop ring is provided with four inwardly recessed grooves, which are located at the connection of the buckle.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: Compared to traditional bulbs or T-bulbs, this lamp eliminates the bulb body, allowing the lamp holder to be mounted in the mounting hole via a connector. The LED light source board is directly mounted on the lampshade. The embedded connection between the LED light source board and the mounting slot ensures a secure connection and provides some dust protection. The exposed back of the LED light source board allows for better heat dissipation. For indoor use, rain protection is not a concern, fully meeting lighting requirements. Furthermore, it is more minimalist than existing bulbs, with lower manufacturing costs and a smaller overall size, significantly reducing transportation and sales costs for manufacturers.

Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0017] like Figure 1 and Figure 2 As shown, an indoor LED bulb includes a lamp holder 4, a lampshade 1, an LED light source board 6, and a connector 5. The lampshade 1 has an inwardly recessed mounting groove 3 on the inner side of its open end. The LED light source board 6 has a mounting hole 8 in the middle. The bottom of the connector 5 is engaged in the mounting hole 8. The mounting hole 8 is located on the connector 5. The LED light source board 6 is embedded in the mounting groove 3 for fixation. The back of the LED light source board 6 is exposed.

[0018] In the actual assembly process, the main body of the LED light source board 6 is a circular aluminum substrate. LED chips, diodes, electrofusion and other electronic components are attached to the front of the aluminum substrate. A mounting hole 8 is formed in the middle of the LED light source board 6 by punching. The connector 5 is snapped into the mounting hole 8 as a carrier for mounting the lamp head 4. The signal line of the lamp head 4 passes through the mounting hole 8 and is soldered to the LED light source board 6 to form a passage. The LED light source board 6 is pressed down from the top of the lamp cover 1 and embedded into the mounting groove 3 by extrusion. Since the lamp cover 1 is made of plastic, the LED light source board 6, whose diameter is larger than the lamp cover 1 and smaller than the mounting groove 3, can be installed by extrusion deformation. After installation, the back of the LED light source board 6 of the LED bulb is exposed and can be directly dissipated. Compared to traditional bulbs or T-bulbs, this design eliminates the need for a separate lamp body, replacing it with a small connector 5. This provides a secure connection and some dust protection. The back of the LED light source board 6 is exposed, resulting in better heat dissipation. Since it's intended for indoor use, rainwater ingress is not a concern, thus meeting the requirements for enclosed lighting fixtures. Furthermore, it's more minimalist than existing bulbs, with lower manufacturing costs and a smaller overall size, significantly reducing transportation and sales costs for manufacturers.

[0019] For underdeveloped countries or developing countries, bulb lamps are the main market. People in these countries need the most basic and cheaper lighting fixtures. The lamps in this application can be sold at a lower price because the cost is lower, which can better meet the purchasing needs of this group and provide them with more affordable lighting products.

[0020] Further improvements include, for example Figure 3 As shown, the axial section of the lampshade 1 is U-shaped, and the inner sidewall of the lampshade 1 is provided with several outwardly protruding limiting ribs 7. The top of the limiting ribs 7 is flush with the lower side of the mounting groove 3.

[0021] The structure of the lampshade 1 is one of the commonly used shapes for lampshades 1. It has lower product improvement costs and greater versatility. However, since the LED light source board 6 is forcibly squeezed in, and the depth and height of the mounting groove 3 are limited, it is easy for the mounting groove 3 to be missed due to excessive squeezing force during assembly. Therefore, multiple outwardly protruding limiting ribs 7 are formed on the inner side wall of the lampshade 1, and the top of the limiting ribs 7 is flush with the lower side of the mounting groove 3. When the LED light source board 6 is misaligned during installation, it can be stopped by the top of the outwardly protruding limiting ribs 7, thereby avoiding misalignment of the LED light source board 6 during installation and making the embedding of the LED light source board 6 faster and more accurate.

[0022] The limiting ribs 7 are generally 4 to 6 in number and evenly distributed in a ring. They are distributed along the axial direction of the side wall of the lampshade 1. During assembly, they can ensure the positional accuracy of each area when it is embedded and avoid local compression that is too deep.

[0023] A further improvement is made by providing a flared guide port 2 at the opening end of the lampshade 1.

[0024] Since both the lampshade 1 and the LED light source board 6 have a certain degree of rigidity, and the inner diameter of the lampshade 1 is smaller than that of the LED light source board 6, it is not easy to quickly insert the LED light source board 6 into the lampshade 1 during the initial installation. Therefore, after forming a flared guide port 2 at the opening end of the lampshade 1, it is easier to assemble the LED light source board 6 without affecting the sealing effect.

[0025] Further improvements include, such as Figure 4 As shown, the mounting hole 8 has a square structure, and the corners of the mounting hole 8 are rounded.

[0026] Because the connector 5 snaps into the mounting hole 8, the conventional circular mounting hole 8 allows the mounting seat to rotate after installation, while the two signal wires are fixed at both ends. This can easily cause the two signal wires to detach after the mounting seat rotates, affecting power supply. Therefore, to avoid damage to the lamp due to rotation after the mounting seat is fixed, the mounting hole 8 is made into a square structure with rounded corners. The rounded corners are large arcs, making the mounting hole 8 a near-circular square hole or a near-square round hole. After the mounting seat is snapped in, the combination of the horizontal and rounded sections acts as a limit, preventing rotation after the mounting seat is installed. Simultaneously, the aluminum substrate impacted by the mounting hole 8 can also be used as the lamp plate for the downlight, solving the problem of material waste.

[0027] Further improvements include, for example Figure 5 As shown, the connecting seat 5 includes a stop ring 52 with a diameter larger than that of the mounting hole 8, a buckle 54 protruding downward at the bottom of the stop ring 52, and a connecting ring 51 on the stop ring 52. The lamp head 4 is mounted on the connecting ring 51.

[0028] The outer diameter of the stop ring 52 is slightly larger than the diameter of the mounting hole 8, while the buckle 54 has an L-shaped structure that protrudes downward. During assembly, the buckle 54 can be fixed by simply inserting it into the mounting hole 8 and engaging with it. The structure is simple and easy to assemble. The back of the stop ring 52 protrudes upward to form a connecting ring 51, which facilitates the installation and fixation of the lamp holder 4. Moreover, the entire connecting seat 5 is small in size and low in height, effectively reducing production costs, overall weight, and overall height and volume.

[0029] A further improvement is that four buckles 54 are evenly arranged around the bottom of the stop ring 52, and the buckles 54 have an arc-shaped structure that engages with the corner of the mounting hole 8.

[0030] Because the corner of mounting hole 8 has a large arc transition, with its arc length exceeding the length of the horizontal segment, the buckle 54 is designed as an arc structure and snaps into place at the corner of mounting hole 8. This provides a wider installation range and makes operation more convenient. The arc length of buckle 54 is less than the arc length of the corner, resulting in a wider installation position during assembly. Although there is a certain rotation angle after insertion, it is sufficient to ensure both quick assembly and a stable connection.

[0031] Meanwhile, the bottom of the stop ring 52 is uniformly provided with four inwardly recessed grooves 53, which are located at the connection of the buckle 54.

[0032] When the clip 54 is engaged with the LED light board, in order to ensure the firmness and stability of the engagement, the L-shaped barb contact surface of the clip 54 and the LED light board installation height between the stop ring 52 are basically the same. This can easily lead to insufficient installation height due to tolerance issues during installation, thus preventing the clip 54 from being quickly and fully engaged. Therefore, a recessed groove 53 is formed on the stop ring 52 at the connection point of the clip 54. The groove 53 further increases the local installation height between the clip 54 and the stop ring 52, so that when the installation height between the stop ring 52 and the clip 54 is insufficient, the groove 53 can compensate for it, allowing the clip 54 to achieve the purpose of being engaged. The design of the groove 53 ensures that the installation height between the clip 54 and the stop ring 52 plane is the same as or slightly smaller than the thickness of the LED light board, so that assembly can be achieved.

[0033] The above embodiments are merely preferred embodiments of this application and should not be construed as limiting the scope of protection of this application. Any non-substantial changes and substitutions made by those skilled in the art based on this application shall fall within the scope of protection claimed by this application.
