Description

Technical Field

[0001] This utility model relates to the field of lighting equipment technology, and in particular to lamp holder assemblies, light bulbs having lamp holder assemblies, and light strips. Background Technology

[0002] In traditional lighting equipment, lamp holder assemblies generally adopt an all-copper design, meaning the screw-in portion at the end of the lamp holder is made of copper, such as E27 and E14 standard screw-in lamp holders. Although copper has excellent conductivity and mechanical strength, it is expensive, accounting for more than 40% of the total cost of the lamp holder, and requires precision machining, further increasing production costs. Furthermore, copper tips exposed to air for extended periods are prone to oxidation, forming a copper oxide film, leading to increased contact resistance, increased heat generation, and even the risk of open circuits. In addition, the all-copper design results in material waste in low-power or non-high-precision applications, and copper threads are prone to wear and deformation after frequent tightening.

Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0038] In traditional lighting equipment, lamp holder assemblies generally adopt an all-copper design, meaning the screw-in portion at the end of the lamp holder is made of copper, such as E27 and E14 standard screw-in lamp holders. Although copper has excellent conductivity and mechanical strength, it is expensive, accounting for more than 40% of the total cost of the lamp holder, and requires precision machining, further increasing production costs. Furthermore, copper tips exposed to air for extended periods are prone to oxidation, forming a copper oxide film, leading to increased contact resistance, increased heat generation, and even the risk of open circuits. In addition, the all-copper design results in material waste in low-power or non-high-precision applications, and copper threads are prone to wear and deformation after frequent tightening.

[0039] Therefore, such as Figures 1 to 4 As shown, the lamp holder assembly proposed in this utility model includes a lamp holder base 100 and a first conductive element 200 and a second conductive element 300 mounted on the outer wall of the lamp holder base 100. The lamp holder base 100 is made of insulating material and can be used to mount a light source 400. The first conductive element 200 and the second conductive element 300 are made of conductive material, such as copper, iron, gold, titanium, or other metals or alloys. Specifically, the second conductive element 300 is arranged separately from the first conductive element 200. The first conductive element 200 and the second conductive element 300 are electrically connected to the positive and negative terminals of the light source 400, respectively. Furthermore, the first conductive element 200 and the second conductive element 300 can be electrically connected to the positive and negative terminals of a driving power supply to supply power to the light source 400. It should be noted that by adopting an insulated lamp holder 100 and a separate first conductive component 200 and second conductive component 300 design, compared to the traditional all-copper lamp holder structure, this structure only requires the use of conductive material in certain areas, namely, the first conductive component 200 and the second conductive component 300 are conductive materials, significantly reducing production costs. Replacing the all-copper material with a plastic lamp holder 100 can reduce material costs by more than 30%, further optimizing costs. Secondly, the insulated lamp holder 100 fundamentally avoids the aging problem caused by copper oxidation, exhibiting better anti-aging performance. Furthermore, the first conductive component 200 and the second conductive component 300 can be connected to a driving power supply, powering the light source 400 to emit light and achieving circuit conduction. In addition, this design is compatible with two conductive components arranged radially opposite each other or axially spaced, allowing for the mating of different screw-type or bayonet-type lamp holders, expanding the flexibility of application scenarios.

[0040] In some embodiments, the first conductive element and the second conductive element are arranged opposite each other radially in the lamp holder (not shown in the figure). For example, both the first and second conductive elements are semi-annular. When the first and second conductive elements are on the same horizontal plane, the central angle between the semi-annular first and second conductive elements is less than 180°; when the first and second conductive elements are staggered, the central angle between the semi-annular first and second conductive elements can be 1° to 359°. Therefore, in some applications, the lamp holder is inserted directly into the lamp base. After insertion, the positive and negative conductive elements inside the lamp base are electrically connected to the first and second conductive elements, respectively.

[0041] like Figure 2 As shown, in other applications, the lamp holder 100 is provided with a threaded post 110. The threaded post 110 is used to screw into the lamp holder and drive the first conductive element 200 and the second conductive element 300 to abut against the positive and negative conductive elements in the lamp holder for conduction. The lamp holder 100 is screwed into the lamp holder by rotation. This screwing action alone completes the crimping and conduction of the conductive elements, simplifying the installation steps and improving assembly efficiency. This is suitable for applications such as Christmas lights and outdoor string lights. Simultaneously, the axial pressure generated by the threaded connection during screwing ensures stable contact between the first conductive element 200 and the positive conductive element, and between the second conductive element 300 and the negative conductive element. Even under vibration or shock environments, it maintains good electrical connection performance, making it particularly suitable for applications requiring vibration resistance, such as automotive lighting and industrial equipment. (Refer to...) Figure 1 and Figure 3 In some embodiments of this utility model, the first conductive element 200 and the second conductive element 300 are arranged axially at a distance from each other in the lamp holder 100. This effectively avoids the risk of short circuits that may be caused by the small distance between the first conductive element 200 and the second conductive element 300. Especially when used in high-voltage or humid environments, the axial distance ensures sufficient electrical safety distance. At the same time, this design conforms to the structural characteristics of most standard lamp holders, enabling precise alignment and connection between the conductive elements in the lamp holder 100 and the conductive elements in the lamp holder, improving assembly efficiency and power supply stability, and reducing overheating or open circuit problems caused by poor contact.

[0042] Refer to Figures 1 to 3In some embodiments of this utility model, the outer wall of the lamp holder 100 is provided with a first mounting groove 101 and a second mounting groove 102. The first conductive element 200 is installed in the first mounting groove 101, and the second conductive element 300 is installed in the second mounting groove 102. The design of the first mounting groove 101 and the second mounting groove 102 provides precise installation positioning for the first conductive element 200 and the second conductive element 300, respectively. This structural design not only simplifies the assembly process but also reduces production costs. Specifically, both the first mounting groove 101 and the second mounting groove 102 are annular. The shape of the first conductive element 200 matches the first mounting groove 101 and is interference-fitted with it. The shape of the second conductive element 300 matches the second mounting groove 102 and is interference-fitted with it, ensuring a tighter and more reliable fit between the conductive element and the mounting groove. The interference fit ensures that the conductive element can maintain a stable connection even under harsh environments such as high temperature and vibration, and will not loosen due to thermal expansion and contraction or mechanical vibration. Furthermore, the annular structure creates a 360° continuous conductive surface for the conductive components, which significantly reduces contact resistance, improves conductivity, and reduces energy loss compared to traditional segmented conductive sheet designs. In some embodiments of this invention, the inner wall of the lamp holder 100 is provided with a first wire channel 103 and a second wire channel 104. The first wire channel 103 extends towards and communicates with the first mounting groove 101, while the second wire channel 104 extends towards and communicates with the second mounting groove 102. The design of the first wire channel 103 and the second wire channel 104 provides a safe and reliable wiring path for the light source 400's wires. This structural design effectively protects the wires from external wear or compression, extending their service life. Additionally, the connection between the wire channel and the mounting groove makes the connection between the wires and the conductive components more convenient and efficient, facilitating automated production assembly and improving production efficiency and product quality consistency.

[0043] Refer to Figure 4 In some embodiments of this utility model, the first conductive element 200 and the second conductive element 300 are respectively located at both ends of the screw thread 110 along its axial direction. On the one hand, this utilizes the axial space of the screw thread 110 to maximize the spacing between the conductive elements, thus meeting the safety requirements of high-voltage insulation. On the other hand, the torque balance formed by the arrangement at both ends prevents misalignment when the lamp holder assembly is screwed in, ensuring correct alignment of the conductive elements and electrodes, and improving assembly accuracy and reliability. Furthermore, this ensures that the conductive elements within the lamp holder 100 only contact and conduct electricity with the conductive elements within the lamp holder after the lamp holder 100 is fully screwed in and installed in the lamp holder.

[0044] Optionally, the lamp holder 100 is made of plastic, while the first conductive component 200 and the second conductive component 300 are made of copper. This achieves an optimized balance between cost and performance. The plastic material significantly reduces the material cost of the lamp holder 100 while providing good insulation and mechanical strength. The copper conductive components ensure excellent conductivity and corrosion resistance. By using copper in specific areas, electrical performance requirements are met while controlling overall cost. Furthermore, the plastic base has a high heat distortion temperature, allowing it to remain stable in high-temperature environments and extending the product's lifespan.

[0045] Refer to Figure 5 The light bulb according to an embodiment of the present invention includes a lamp holder assembly according to an embodiment of the present invention. By adopting the lamp holder assembly according to an embodiment of the present invention, the overall production cost of the light bulb is significantly reduced, while maintaining good electrical performance and mechanical reliability. Furthermore, the modular design of the lamp holder assembly simplifies the bulb manufacturing process, improves assembly efficiency and product consistency. In addition, the plastic lamp holder 100 has good corrosion resistance and anti-aging properties, extending the bulb's service life and reducing the frequency of maintenance and replacement.

[0047] The light strip according to an embodiment of the present invention includes a lamp holder assembly according to an embodiment of the present invention. It should be noted that by adopting the lamp holder assembly of the present invention, the electrical connection between the light strip modules is more reliable and stable. Furthermore, the insulation performance of the plastic lamp holder 100 ensures that the spacing between the light strip modules can be further reduced, improving space utilization and achieving a higher density flexible lighting layout.

[0048] Other configurations and operations of the light strip according to the embodiments of this utility model are known to those skilled in the art and will not be described in detail here.
