Detailed Implementation

[0027] The following is in conjunction with the appendix Figures 1 to 7 This utility model will be described in detail.

[0028] This utility model relates to a convenient positioning and assembly lamp, comprising a lamp holder 1 and a bulb 2 electrically connected to the lamp holder 1. One end of the lamp holder 1 is provided with an assembly groove 3 having an opening. The assembly groove 3 has at least two electrical sockets 31 inside, and conductive terminals 32 are installed inside the electrical sockets 31. The inner sidewall of the assembly groove 3 is also provided with an annular groove 33. The other end of the lamp holder 1 is connected to an external wire 4, which is electrically connected to the conductive terminals 32. The bulb 2 includes a bulb shell 21, a sealing seat 22, and a wick assembly 23 disposed inside the bulb shell 21. The sealing seat 22 is disposed outside the opening of the bulb shell 21. The sealing seat 22 seals and covers the entire opening of the bulb shell 21; the lamp wick assembly 23 includes a first metal wire 231, a light source element 232, and a second metal wire 233 connected in sequence, the other ends of the first metal wire 231 and the second metal wire 233 both pass through the sealing seat 22 and form a first conductive plug post 234 and a second conductive plug post 235; the first conductive plug post 234 and the second conductive plug post 235 can be inserted into the electrical socket 31 and electrically connected to the conductive terminal 32; the outer wall of the sealing seat 22 is also provided with a protruding ring 221, which is adapted to the annular groove 33 so that the bulb 2 is installed in the lamp holder 1. The lamp holder 1 and the sealing seat 22 of this technical solution can be circular or square or other shapes.

[0029] Compared with traditional lamps, this utility model has the following advantages: 1. Low lamp molding cost: The lamp achieves electrical conduction directly through the insertion of the plug and conductive wire. Only two small conductive terminals need to be installed inside the plug, eliminating the need to mold large-volume, high-cost metal threaded copper sleeves and metal threaded heads, thus significantly reducing the lamp molding cost and making production more efficient; 2. Convenient and quick lamp assembly: The lamp holder and bulb are directly connected by a snap ring, eliminating the traditional threaded connection step. The assembly method is convenient and effectively improves the lamp assembly efficiency; 3. High waterproof performance: The bulb opening is integrally injection molded with a sealing seat, completely isolating external moisture from the bulb and effectively extending the lamp's service life.

[0030] To accelerate the assembly efficiency of the overall lamp and prevent the positive and negative electrodes from being mistakenly inserted, a positioning groove 34 is also provided on the side wall of the assembly groove 3. A positioning post 222 is provided on the outer side wall of the sealing seat 22 corresponding to the positioning groove 34. The positioning post 222 is positioned and assembled in the direction of the positioning groove 34, which can quickly find the correct assembly direction of the lamp.

[0031] Furthermore, the positioning groove 34 is perpendicular to the annular groove 33, and the positioning groove 34 is connected to the annular groove 33.

[0032] In one embodiment, a fixing seat 35 protrudes from the center of the bottom of the assembly groove 3, and the electrical insertion hole 31 is disposed in the fixing seat 35; the sealing seat 22 is provided with a slot 223, and the first conductive insertion post 234 and the second conductive insertion post 235 are both disposed in the slot 223, and the fixing seat 35 can be inserted into the slot 223. This structure makes the assembly of the sealing seat 22 and the assembly groove 3 a two-stage insertion, thereby improving the connection strength between the lamp holder 1 and the bulb 2, and further reducing the influence of the external environment on the internal electrical connection structure of the lamp holder 1, thus extending the service life of the lamp.

[0033] In this technical solution, a positioning block 224 with a plane protrudes from the inner side of the slot 223, and the fixing seat 35 is provided with a positioning plane 351 corresponding to the positioning block 224. When the slot 223 and the fixing seat 35 are assembled together, in addition to the positioning of the positioning post 222, secondary positioning is also performed by the positioning plane 351 and the positioning block 224 to improve the assembly accuracy.

[0034] Preferably, the lamp wick assembly 23 further includes a plastic base 5, which is disposed inside the opening of the bulb shell 21. The plastic base 5 has wire holes 51 for the first metal wire 231 and the second metal wire 233 to pass through. The plastic base 5 can assist in positioning the first metal wire 231 and the second metal wire 233. At the same time, the plastic base 5 can cooperate with the sealing seat 22 to form a secondary seal for the lamp, significantly improving the waterproof performance of the bulb 2.

[0035] Preferably, both the first metal wire 231 and the second metal wire 233 are composed of two parts: a conductive wire 236 and a conductive post 237. The diameter of the conductive post 237 is larger than the diameter of the conductive wire 236. The conductive wire 236 is electrically connected to the light source component 232, and the conductive post 237 extends through the sealing seat 22 into the slot 223. The ends of the conductive post 237 form a first conductive insertion post 234 and a second conductive insertion post 235 with high strength, used for interlocking with the electrical connector. This structure ensures that the first metal wire 231 and the second metal wire 233 have sufficient strength to form an interlock with the electrical connector, while also saving raw materials for the metal wires, further reducing manufacturing costs. For example, Figure 3 As shown, the first metal wire 231 and the second metal wire 233 are also provided with heat dissipation resistors 6.

[0036] In this technical solution, the light source 232 can be as follows: Figure 3 The LED filament shown can also be an LED chip, or even a lower-cost T-shaped LED light board, such as... Figure 7As shown, the light source 232 includes a substrate 238 and an elongated light source section 239 disposed on the top of the substrate 238. The elongated light source section 239 is provided with multiple LED chips 240 and coated with phosphor. The substrate 238 is provided with positive and negative conductive metal sheets. The first metal wire 231 and the second metal wire 233 are both soldered to the conductive metal sheets of the substrate 238 and electrically connected to the LED chips 240. This structure of the light source 232 can save some metal wires and can directly integrate the heat dissipation resistor 6 onto the substrate 238, saving some components and significantly reducing costs.

[0037] To improve the stability of the connection between the external wire 4 and the lamp holder 1 and to prevent poor contact of the lamp wire, the end of the external wire 4 connected to the lamp holder 1 is injection molded with a connector 41.

[0038] Based on the above technical solution, the inventors also symmetrically provided at least one set of anti-slip surfaces 42 on the outer surface of the connector 41 to grip and position the lamp holder 1, making it easier to install or remove the bulb 2 from the lamp holder 1.

[0039] like Figure 2 As shown, the bulb shell 21 also contains several fluorescent filaments 211. The fluorescent filaments 211 are colored and can reflect the light from the lamp in different directions, which helps to increase the light variation of the lamp, thereby improving the user's visual experience and optimizing the decorative effect of the lamp.

[0040] This utility model also includes a string of lights, such as Figure 6 As shown, the lamp includes the aforementioned lighting fixture, as well as a main power cord 7, a male plug 8, a female socket 9, and multiple string light connectors 10. The male plug 8 and female socket 9 are respectively located at both ends of the main power cord 7. The multiple string light connectors 10 are evenly distributed in the middle of the main power cord 7. The external wire 4 extends into the string light connector 10 and is electrically connected to the main power cord 7. This string light possesses all the structural advantages of the aforementioned lighting fixture, and also better meets the existing user needs for decorative lighting.

[0041] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
