[0035] See Figures 1 to 10The specific embodiment shown in this utility model discloses a bulb structure, including: a bulb body 10, a bulb 20, a bracket 30, a negative electrode cap 40, a positive electrode base 50, and a positive electrode cap 60. The bulb 20 is provided with a positive electrode wire 21 and a negative electrode wire 22. The bracket 30 is connected to the top of the bulb body 10, the negative electrode cap 40 is connected to the bulb body 10, the positive electrode base 50 is connected to the negative electrode cap 40, and the positive electrode cap 60 is connected to the positive electrode base 50. The bulb 20 is located inside the bulb body 10, and the positive electrode wire 21 extends upward sequentially from the bracket 30 and the negative electrode cap 40 and is connected to the positive electrode base 50, so that the positive electrode wire 21 and the positive electrode cap 60 form an electrical connection. The negative electrode wire 22 extends upward from the side wall of the bracket 30 and is connected to the inner wall of the negative electrode cap 40, so that the negative electrode wire 22 and the negative electrode cap 40 form an electrical connection.
[0036] Specifically, the positive electrode wire 21 extends upwards sequentially from the bracket 30 and the negative electrode cap 40 and connects to the positive electrode base 50, thus forming an electrical connection between the positive electrode wire 21 and the positive electrode cap 60. The negative electrode wire 22 extends upwards from the side wall of the bracket 30 and connects to the inner wall of the negative electrode cap 40, thus forming an electrical connection between the negative electrode wire 22 and the negative electrode cap 40. In other words, the positive electrode wire 21 and the negative electrode wire 22 can form reliable electrical connections with the positive electrode cap 60 and the negative electrode cap 40 respectively, without the need for welding. This method achieves a solderless process, significantly simplifying the production process, improving overall production efficiency, reducing production costs, and demonstrating strong practicality. Furthermore, the application of the solderless process makes operations on the production line smoother, reducing waiting time and quality control steps caused by welding. At the same time, by avoiding potential welding defects and damage to the wick 20 during the welding process, this bulb structure has a higher yield and more stable production efficiency during production. This not only helps to shorten the product delivery cycle but also better meets the market demand for high-quality bulb products. Furthermore, welding processes consume significant amounts of energy, materials, and human resources, and require regular maintenance and upkeep of welding equipment. Adopting a weld-free process significantly reduces production costs. On one hand, it reduces the costs of welding equipment, consumables, and labor; on the other hand, the simplified production process lowers scrap and rework rates, further reducing production costs. Additionally, the weld-free process avoids problems such as thermal stress, oxidation, and corrosion that can occur during welding, thereby improving the stability and reliability of the bulb structure. Moreover, since electrical connections are achieved through physical contact, it offers better conductivity and lower contact resistance, which helps extend the bulb's lifespan and improve its performance.
[0037] See Figure 2 , Figure 8 and Figure 9As shown, in one embodiment, the inner side of the positive electrode base 50 is provided with a groove 51 along the axial direction, and a first notch 52 is provided at the top of the groove 51. The positive electrode wire 21 is close to the groove 51 and extends out of the first notch 52.
[0038] Specifically, there are several grooves 51, evenly distributed on the inner side of the positive electrode base 50. One of the grooves 51 has a first notch 52 at its top. The groove 51 is used to connect and fix the positive electrode cap 60. By cleverly designing the grooves 51 axially on the inner side of the positive electrode base 50 and opening the first notch 52 at the top of the grooves 51, effective fixing and protection of the positive electrode wire 21 is achieved. When the positive electrode wire 21 is arranged close to the groove 51 and extends out of the first notch 52, its position is accurately positioned. More importantly, when the positive electrode cap 60 is inserted into the positive electrode base 50, the positive electrode cap 60 will naturally squeeze the positive electrode wire 21 into the area of the groove 51. This design not only enhances the stability of the positive electrode wire 21 during assembly, but also significantly reduces the risk of displacement of the positive electrode wire 21 during use. Furthermore, this structural design allows for a more stable electrical connection between the positive electrode wire 21 and the positive electrode cap 60. Reduced displacement means improved stability and reliability of the electrical connection point, ensuring the stability and safety of the entire bulb structure during long-term operation. In addition, this design helps reduce the risk of circuit failures or short circuits that may be caused by displacement of the positive electrode wire 21, further extending the product's lifespan and overall performance.
[0039] See Figures 2 to 4 As shown, in one embodiment, the positive electrode cap 60 is provided with a threaded layer 61, which is used to press the positive electrode wire 21.
[0040] Specifically, by designing a threaded layer 61 on the positive electrode cap 60, effective compression and positioning of the positive electrode wire 21 are cleverly achieved. This design not only enhances the physical contact between the positive electrode cap 60 and the positive electrode wire 21, but also significantly improves the stability of the positive electrode wire 21 during assembly and use through the tight fit of the threaded layer 61. When the positive electrode cap 60 is pressed into the positive electrode seat 50, its threaded layer 61 tightly adheres to and compresses the positive electrode wire 21, forming a robust locking mechanism. This mechanism effectively prevents the positive electrode wire 21 from shifting during vibration, impact, or long-term use, thereby ensuring the stability and reliability of the electrical connection between the positive electrode wire 21 and the positive electrode cap 60. In addition, the design of the threaded layer 61 brings additional advantages; it can disperse and buffer external stress to a certain extent, reducing the risk of damage to the positive electrode wire 21 or circuit failure caused by stress concentration. At the same time, the tight fit of the threaded layer 61 also helps to improve current transmission efficiency and reduce energy loss, thereby improving the performance and efficiency of the entire bulb structure.
[0041] See Figures 2 to 4 As shown, in one embodiment, the positive electrode base 50 is provided with an annular groove 53, and the negative electrode cap 40 has an opening 41 corresponding to the annular groove 53.
[0042] Specifically, by designing an annular groove 53 in the middle section of the positive electrode holder 50 and opening a corresponding opening 41 on the negative electrode cap 40, a unique and effective sealed connection is achieved between the positive electrode holder 50 and the negative electrode cap 40. This design not only enhances the connection stability between the positive electrode holder 50 and the negative electrode cap 40 but also significantly improves their sealing performance. Furthermore, the engagement of the annular groove 53 and the opening 41 forms a tight locking mechanism. When the negative electrode cap 40 is installed on the positive electrode holder 50, the opening 41 can precisely embed into the annular groove 53, thus achieving a secure connection. This connection method effectively prevents external moisture, dust, or other contaminants from entering the bulb structure, avoiding negative impacts on bulb performance, and ensuring stable operation of the bulb under various environmental conditions. In addition, the sealed connection of the annular groove 53 and the opening 41 also contributes to improving the safety of the bulb structure.
[0043] See Figure 3 , Figure 5 , Figure 6 , Figure 7 and Figure 10 As shown, in one embodiment, the bracket 30 is provided with a positive electrode channel 31 and a negative electrode channel 32 along the axial direction, the positive electrode wire 21 extends along the positive electrode channel 31, and the negative electrode wire 22 extends along the negative electrode channel 32.
[0044] Specifically, by cleverly designing the positive electrode channel 31 and negative electrode channel 32 along the axial direction on the bracket 30, the positive electrode wire 21 and negative electrode wire 22 are extended in an orderly and separate manner. This design not only optimizes the internal spatial layout of the bulb but also significantly improves stability and safety. Furthermore, the separate design of the positive electrode channel 31 and negative electrode channel 32 ensures that the positive electrode wire 21 and negative electrode wire 22 will not interfere with or contact each other during extension, thus effectively avoiding the risk of short circuits. In addition, the orderly arrangement of the positive electrode channel 31 and negative electrode channel 32 also facilitates the bulb assembly process. Production personnel can easily connect the positive electrode wire 21 and negative electrode wire 22 to their respective electrode cap positions according to the channel guides, without worrying about wire confusion or installation errors. This not only improves production efficiency but also reduces the failure rate caused by assembly errors.
[0045] See Figure 2 , Figure 3 , Figure 5 , Figure 6 , Figure 7 and Figure 10 As shown, in one embodiment, a resistor 23 is connected to the middle section of the positive electrode wire 21 and / or the negative electrode wire 22, and the resistor 23 is installed in the positive electrode channel 31 and / or the negative electrode channel 32.
[0046] Specifically, by flexibly placing the resistor 23 on the positive lead 21 and / or the negative lead 22 and cleverly installing it in the positive channel 31 and / or the negative channel 32, not only is precise current control achieved, but it also brings significant limiting effects and space-saving advantages. This design greatly improves the flexibility and efficiency of bulb production, while also enhancing product reliability and safety. Furthermore, the addition of the resistor 23 not only allows for adjusting the current according to the actual needs of bulb production, ensuring the bulb emits light and heat within its normal operating range, but also serves as a limiting element in the positive channel 31 and / or the negative channel 32 through its physical size and shape. This limiting design effectively prevents the resistor 23 from shaking or misaligning within the channel, ensuring a stable connection between the lead and the electrode cap, thereby improving the electrical performance and durability of the bulb. Furthermore, directly mounting the resistor 23 within the positive electrode channel 31 and / or the negative electrode channel 32 fully utilizes the space within the channels, avoiding the need for additional limiting structures or components. This design not only simplifies the internal structure of the bulb and reduces production costs but also makes the bulb more compact, lightweight, and easier to install and transport. Additionally, this technical feature optimizes material utilization. By rationally designing and arranging the resistor 23, it satisfies the requirements for current control and limiting while minimizing material waste, aligning with the modern manufacturing industry's requirements for energy conservation, emission reduction, and sustainable development.
[0047] See Figure 3 As shown, in one embodiment, the top of the bracket 30 is provided with an annular boss 33, which abuts against the lamp body 10.
[0048] Specifically, by designing an annular protrusion 33 on the top of the bracket 30 and forming an abutment structure with the lamp body 10, a stable and reliable connection between the bracket 30 and the lamp body 10 is achieved. This design not only improves the overall stability and safety of the bulb but also brings several technical benefits. First, the abutment structure between the annular protrusion 33 and the top of the lamp body 10 effectively enhances the support of the bracket 30 for the lamp body 10. This design allows the bracket 30 to more firmly fix the lamp body 10, preventing it from shaking or falling off during installation or use, thus ensuring the stability and safety of the bulb. Second, the design of the annular protrusion 33 also helps to achieve the bulb's sealing performance. When the annular protrusion 33 is tightly abutted against the top of the lamp body 10, it forms an effective sealing barrier, preventing external dust, moisture, and other impurities from entering the bulb and protecting the internal electrical components and wiring from damage. More importantly, this design also reflects the optimization of material utilization. By rationally designing the size and shape of the annular protrusion 33, it satisfies both the needs of support and sealing while minimizing material waste, meeting the requirements of energy conservation, emission reduction, and sustainable development in modern manufacturing.
[0049] See Figure 2 , Figure 6 , Figure 7 and Figure 10 As shown, in one embodiment, the annular boss 33 has a second notch 34, and the negative electrode wire 22 extends out of the second notch 34.
[0050] Specifically, by cleverly creating a second notch 34 on the annular boss 33, allowing the negative electrode wire 22 to extend out through the second notch 34, the orderly and safe exit of the negative electrode wire 22 within the bulb is achieved. This design not only optimizes the internal structural layout of the bulb but also brings several technical benefits. First, the second notch 34 provides a convenient channel for the exit of the negative electrode wire 22. During bulb assembly, the negative electrode wire 22 can easily extend through the second notch 34 and connect to the negative electrode cap 40 without the need for additional wire drilling or winding operations, thus simplifying the assembly process and improving production efficiency. Second, this design enhances the stability and safety of the negative electrode wire 22 within the bulb. The negative electrode wire 22, exiting through the second notch 34, has a clearly defined position, preventing it from swinging randomly inside the bulb or making unnecessary contact with other components, thereby reducing the risk of electrical faults or short circuits. In addition, the opening of the second notch 34 also helps to improve the sealing performance of the bulb. Based on the tight contact between the annular boss 33 and the lamp body 10, the design of the second notch 34 can ensure that the negative wire 22 will not damage the sealing structure of the bulb when it is led out, preventing external dust, moisture and other impurities from entering the bulb through the wire, thus ensuring the cleanliness and dryness of the bulb's internal environment.
[0051] See Figure 2 , Figure 5 , Figure 6 ,and Figure 7 As shown, in one embodiment, the end of the negative electrode wire 22 is shaped like a "7" and the end of the negative electrode wire 22 is attached to the second notch 34.
[0052] Specifically, by designing the end of the negative electrode wire 22 to be in the shape of a "7" and cleverly attaching it to the second notch 34, a stable connection and convenient exit of the negative electrode wire 22 within the bulb are achieved. This innovative design not only enhances the structural stability of the bulb but also brings several technical benefits. First, the "7"-shaped end of the negative electrode wire 22, attached to the second notch 34, forms a stable mechanical connection. Compared to traditional welding or plugging methods, this connection method has higher strength and stability, effectively preventing the negative electrode wire 22 from detaching or loosening due to force or vibration during use, thus ensuring the electrical performance and safety of the bulb. Second, this design simplifies the bulb assembly process. The "7"-shaped end of the negative electrode wire 22 can be directly attached to the second notch 34 without complex welding or plugging operations, thereby improving assembly efficiency and reducing production costs. Simultaneously, this connection method also facilitates subsequent maintenance and replacement, reducing maintenance costs. In addition, the negative wire 22 at the 7-shaped end can effectively avoid interference with other electrical components or lines by being attached to the second notch 34. This design ensures that the negative wire 22 is laid out reasonably and orderly inside the bulb, preventing electrical faults or safety hazards caused by wires intertwining or overlapping.
[0053] See Figures 1 to 3 As shown, in one embodiment, the negative electrode cap 40 is threaded to the lamp body 10 so that the negative electrode wire 22 abuts against the inner wall of the negative electrode cap 40.
[0054] Specifically, by using a threaded connection to fix the negative electrode cap 40 to the lamp body 10, and ensuring that the negative electrode wire 22 is tightly abutted against the inner wall of the negative electrode cap 40, a stable connection and efficient conductivity of the negative electrode wire 22 within the bulb are achieved. This design not only enhances the electrical performance of the bulb but also brings several technical benefits. First, the threaded connection between the negative electrode cap 40 and the lamp body 10 forms a robust mechanical connection. This connection method has high strength and durability, effectively preventing the negative electrode cap 40 from loosening or falling off due to force or vibration during use, thereby ensuring a stable connection between the negative electrode wire 22 and the lamp body 10, and improving the reliability and safety of the bulb. Second, the tight abutment between the negative electrode wire 22 and the inner wall of the negative electrode cap 40 ensures good electrical contact. This design reduces contact resistance and improves current transmission efficiency, enabling the bulb to maintain stable brightness and power output during operation. Simultaneously, the tight electrical contact also helps prevent electrical faults or short circuits, further enhancing the electrical performance of the bulb. Furthermore, the threaded connection of the negative electrode cap 40 facilitates subsequent maintenance and replacement work. More importantly, the design also reflects the optimization of the overall structure of the bulb. By using a threaded connection to fix the negative electrode cap 40, the internal structure of the bulb can be made more compact and orderly, improving space utilization. At the same time, the threaded connection of the negative electrode cap 40 also increases the stability of the bulb, making it more stable and reliable during installation and use.
[0055] See Figures 1 to 3 ,and Figure 5 As shown, in one embodiment, the negative electrode cap 40 is provided with a plurality of inward protrusions 42 along the radial direction, and the inward protrusions 42 are used to abut against the lamp body 10.
[0056] Specifically, by radially arranging several inward protrusions 42 at the lower end of the negative electrode cap 40, and utilizing these inward protrusions 42 to form an interference fit with the lamp body 10, a tight connection and efficient seal between the negative electrode cap 40 and the lamp body 10 are achieved. This innovative design not only significantly improves the sealing performance of the bulb but also brings about multiple technical benefits. First, the inward protrusions 42 enhance the connection strength between the negative electrode cap 40 and the lamp body 10. These inward protrusions 42 can tightly abut and press against the lamp body 10, forming a strong mechanical connection, effectively preventing the lamp body 10 from loosening or falling off due to force or vibration during use. This design improves the overall stability and reliability of the bulb, ensuring a stable connection between the negative electrode cap 40 and the lamp body 10. Secondly, the interference fit between the inward protrusion 42 and the lamp body 10 significantly improves the bulb's sealing performance. Through tight contact and compression, the inward protrusion 42 effectively prevents external dust, moisture, and other impurities from entering the bulb, maintaining a clean and dry internal environment. This is crucial for extending the bulb's lifespan, improving electrical performance, and preventing electrical malfunctions. Furthermore, this design optimizes the bulb manufacturing process. By precisely controlling the shape, number, and distribution of the inward protrusion 42, precise control of the sealing performance can be achieved, meeting the sealing performance requirements of different application scenarios. Simultaneously, this design simplifies the bulb assembly process, reducing production costs and manufacturing complexity.
