[0002] LED lighting fixtures include light-emitting components and a driver power supply that is connected to the circuitry of the light-emitting components. The light-emitting components include a substrate and LED chips on the substrate. Conventional techniques achieve the circuit connection between the light-emitting components and the driver power supply through soldering, which is a relatively complex manufacturing method.

[0003] Chinese patent CN219933850U discloses an easy-to-assemble LED plug-in lamp. In this design, a connector is provided on the substrate, and the driver power supply has pins that mate with the connector. The connector and pins engage to achieve circuit connection between the driver power supply and the light-emitting component, which is easier to process and assemble than traditional soldering methods.

[0004] However, the above technical solution only changes circuit soldering to circuit plugging. When the driver power supply and the light-emitting component are plugged in, the pins of the driver power supply are small and difficult to position accurately in the automated production process. During the automated assembly of various parts of the LED lamp, the pins are prone to misalignment, resulting in a low yield rate of automated processing. Utility Model Content

[0049] See Figures 1-3 One embodiment of this application provides an LED lamp, including a driver power supply 100, a lamp holder 200, a light-emitting component 300, and a lamp housing.

[0050] See Figures 1-4 The driving power supply 100 includes a circuit board 110 and a first pin 101 and a second pin 102 disposed on the circuit board 110. The driving power supply 100 also includes a circuit element 103 disposed on the circuit board 110 for connecting the first pin 101 and the second pin 102. The first pin 101 includes a vertical segment 105 perpendicular to the circuit board 110 and a horizontal segment 104 parallel to the circuit board 110.

[0051] See Figure 4 The lamp holder 200 has a conductive element 210 for connecting to an external power source and for electrically connecting to a drive power supply 100, such as AC mains power. The conductive element 210 is electrically connected to a second pin 102. Specifically, the conductive element 210 is a hollow post 211 with at least one end open to the second pin 102. The hollow post 211 has an opening 212 open to the conductive element 210 for the second pin 102 to be inserted, facilitating circuit connection. The lamp holder 200 may be, for example, model G23.

[0052] See Figures 3-5 The light-emitting component 300 is assembled and fixed inside the lamp housing. The light-emitting component 300 includes a substrate 310 and LED beads 320 and a connector 330 electrically connected on the substrate 310. The connector 330 has a socket 331. The connector 330 is used to connect with the first pin 101 to realize the electrical connection between the driving power supply and the light-emitting component.

[0053] See Figure 5 The lamp housing includes a tube body 400, a first sealing member 500, and a second sealing member 600. The light-emitting component 300 is assembled and fixed inside the tube body 400. The tube body 400 has an open first end 401 and a second end 402. The first sealing member 500 and the second sealing member 600 are respectively assembled to the first end 401 and the second end 402 to close the tube body 400. The first sealing member 500 is connected to the lamp holder 200 and has a cavity 511 for accommodating the driving power supply 100.

[0054] See Figure 5 A heat sink 700 is disposed inside the tube body 400. The two ends of the heat sink 700 are connected to the first sealing member 500 and the second sealing member 600 respectively via screws 701, facilitating automated assembly of the tube body 400 and the two sealing members. The light-emitting component 300 is fixed to the heat sink 700, indirectly assembled and fixed inside the tube body 400. A first sliding groove 403 is provided inside the tube body 400 for sliding installation of the heat sink 700, which is specifically made of metal such as aluminum. A second sliding groove 710 is provided in the heat sink 700 for sliding installation of the substrate 310. The tube body 400 has a length direction along the line connecting the first end 401 and the second end 402, and a width direction perpendicular to the length direction. The first sliding groove 403 and the second sliding groove 710 respectively restrict the movement of the heat sink 700 and the substrate 310 in the width direction of the tube body 400. As a fixing method, the radiator 700 has mounting holes 720 at both ends along its length. The mounting holes 720 can be opened through the length to form through screw slots. The first sealing member 500 and the second sealing member 600 are connected and fixed to the screw slots at both ends of the radiator 700 by screws 701. The first sealing member 500 and the second sealing member 600 abut against the first end 401 and the second end 402 of the tube body 400, respectively, to fix the tube body 400, the two sealing members, and the radiator 700.

[0055] See Figure 5 and Figure 6Furthermore, the first sealing member 500 has a crossbar 510 located at the first end 401 of the tube body 400. The crossbar 510 is used to position the tube body 400, and the cavity 511 of the first sealing member 500 is formed by the crossbar 510 in a direction away from the tube body 400. The second sealing member 600 has a limiting plate 610 located at the second end 402 of the tube body 400. Both the crossbar 510 and the limiting plate 610 have screw holes 404 for screws 701 to pass through and be fixed to the heat sink 700. The substrate 310 of the light-emitting component 300 is clamped and fixed between the crossbar 510 and the limiting plate 610, realizing the assembly and fixation of the light-emitting component 300, so that the insertion hole 331 of the light-emitting component 300 has a defined relative position with respect to the crossbar 510. The second sealing member 600 includes a separate limiting plate 610 and a decorative cover 620. The second sealing member 600 with the decorative cover 620 has a smooth and flat surface, improving its aesthetics. The limiting plate 610 is provided with a first engaging member 611 on the side away from the tube body 400, and the decorative cover 620 is provided with a second engaging member 621 on the side facing the limiting plate 610. The first engaging member 611 and the second engaging member 621 can be mutually cooperating holes and protrusions, used to achieve the engaging and fixing of the limiting plate 610 and the decorative cover 620.

[0056] See Figure 4 The lamp holder 200 has a positioning part for positioning the driving power supply 100. The positioning part includes a positioning groove 222 adapted to the circuit board 110. The positioning groove 222 is open at one end facing the first sealing member 500 and closed at the other end. The lamp holder 200 has a plug-in part 220 that is inserted into the cavity 511 and has a clearance fit with it (forming the inner wall of the cavity 511). The plug-in part 220 is specifically a cover formed by the lamp holder 200 itself extending towards the tube body 400. The positioning groove 222 is specifically provided in the plug-in part 220. The plug-in part 220 is engaged and fixed with the first sealing member 500. Specifically, the plug-in part 220 is provided with a locking part 223, and the inner wall of the cavity 511 of the first sealing member 500 is provided with a locking part 530 that engages with the locking part 223. The locking part 223 can be, for example, a slot, and the locking part 530 can be, for example, a protrusion that engages with the locking part 223. After the insertion part 220 is inserted into the cavity 511, the engaging part 223 engages with the engaging part 530 to achieve the engagement and fixation of the lamp holder 200 and the first sealing member 500.

[0057] The LED luminaire includes a guide portion 520 that guides the first pin 101 into the socket 331 to enable electrical connection between the driving power supply 100 and the light-emitting component 300.

[0058] See Figures 5-7In one embodiment, the guide portion 520 includes a guide hole 521 disposed on the first sealing member 500 and aligned with the insertion hole 331. Specifically, the guide hole 521 is a tapered hole formed by narrowing in the direction of the tube body 400, and the guide hole 521 is disposed on the crossbar 510. When the first insertion pin 101 reaches the space defined by the guide hole 521, it is guided by the guide hole 521 and aligned with the insertion hole 331 on the insertion socket 330.

[0059] See Figures 8-9 In another embodiment, the guide portion 520 includes a guide ramp 332 disposed on the connector 330. When the first pin 101 contacts the guide ramp 332, it is guided by the guide ramp 332 into the socket 331.

[0060] See Figure 5 The LED lamps provided in each embodiment can be used as plug-in lamps. In the LED lamps provided in each embodiment, since the light-emitting component 300 is assembled on the tube body 400 and the first sealing component 500 is assembled on the first end 401 of the tube body 400, the first sealing component 500, the light-emitting component 300 and the tube body 400 are assembled and fixed together, and thus the socket 331 on the light-emitting component 300 has a relatively unique position relative to the first sealing component 500.

[0061] See Figure 10 During assembly, the driving power supply 100 can be prepositioned to the lamp holder 200, and then the plug-in part 220 of the lamp holder 200 is plugged into the first sealing member 500. The driving power supply 100 then enters the cavity 511 of the first sealing member 500, and the first pin 101 of the driving power supply 100 reaches the guide part 520 under the plugging and engagement.

[0062] The guide portion 520 provides precise guidance and positioning for the first pin 101, so that the first pin 101 is accurately guided into the socket 331 of the light-emitting component 300, while simultaneously completing the snap-fit ​​fixing of the lamp head 200 and the first sealing member 500.

[0063] The embodiments of this application facilitate the precise guidance of the first pin 101 into the socket 331, avoiding a decrease in the yield of LED lamps due to the difficulty in aligning the first pin 101 with the socket 331, and facilitating automated assembly of LED lamps, thereby improving the yield of automated assembly of LED lamps.

[0064] The technical features of the embodiments described above can be combined arbitrarily. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as the combination of these technical features does not contradict each other, it should be considered to be within the scope of this specification. When technical features of different embodiments are embodied in the same drawing, it can be regarded as the drawing also disclosing examples of combinations of the various embodiments involved.

[0065] The embodiments described above are merely examples of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these modifications and improvements all fall within the protection scope of this application.
