Description

Technical Field

[0001] This utility model relates to the field of lighting equipment technology, specifically to a light-emitting component and an LED lamp. Background Technology

[0002] With the development of the times, lighting fixtures have become the most common general lighting method. Among them, LED lights are a superior type of lighting fixture, offering stable illumination, high brightness, and energy efficiency. Current LED lights mainly consist of a lamp base, an LED panel, and a lamp cover over the LED panel. The lamp cover is generally removable to facilitate the installation and removal of the LED panel. The LED panel is connected to an external power supply via a driver. To facilitate lamp assembly and establish a conductive connection, the applicant previously designed a reliable lamp driver (Chinese Utility Model, Authorization Announcement No. CN220750058U), which includes a driver housing, a PCB substrate disposed within the housing, and terminals and conductive plates electrically connected to the PCB substrate. The terminals are connected to an external power supply. The housing also includes a movable support sleeved on the conductive plate. The bottom of the movable support is supported by a spring, and the movable support slides relative to the conductive plate under the action of insertion, exposing the conductive plate. This allows for modular installation of the driver within the electrical area. This utility model integrates the terminals and conductive plates on the driver's PCB substrate, thereby saving on wire connections between the terminals and the driver, and between the light-emitting component and the driver. During assembly, only the external power supply wire needs to be plugged into the terminals. The conductive plates on the driver and the conductive mating parts on the light-emitting component form an electrical connection through insertion, thereby achieving modular installation of the driver within the electrical area.

[0003] In the above scheme, the contact part in the light-emitting component abuts against the movable support and makes the conductive mating part make conductive contact with the conductive sheet. This plug-in structure has a high production cost (the plug-in structure is complex) and is not convenient to assemble flexibly using a robotic arm.

[0004] Therefore, the applicant further improved the conductive connection structure between the driver and the LED light board, simplified the assembly structure, reduced production costs, and enabled the driver to achieve fast and stable assembly and positioning with the LED light board through a robotic arm, thereby improving production efficiency. Utility Model Content

[0005] The purpose of this invention is to develop a light-emitting component and an LED lamp to solve the problems of complex assembly structures of LED lamp drivers and LED lamp boards in the prior art, which lead to high production costs and inconvenience for automated production, thereby improving the production efficiency of LED lamps and reducing production costs.

[0006] This utility model is achieved through the following technical solution: A light-emitting component for an LED lamp includes an LED lamp board and a driver. The driver includes a housing, terminals, and a PCB board disposed within the housing. The input end of the PCB board is electrically connected to the terminals, and the output end of the PCB board extends through the housing with a conductive pin. The LED lamp board is provided with a conductive fixing member, and the conductive pin is conductively inserted into the conductive fixing member.

[0007] The beneficial effects of the above technical solution are as follows: The conductive pins are pins that are inherent to the PCB board during production, unlike the conductive contacts or wires that are assembled later and make conductive connections to the PCB board. During production, the protruding parts of the conductive pins on the PCB board usually need to be cut off with a die to avoid short circuits caused by contact between the pins and to improve aesthetics. This solution breaks away from the conventional processing approach of "cutting off the pins" after PCB board production, and retains the pins in the output area of ​​the PCB board without cutting them off, directly using them as conductive connection structures at the output end to make conductive connections with the LED light board; it saves production processes and materials, reduces production costs, and facilitates automated assembly. During assembly, the PCB board is installed in the housing, the driver is picked up by a robot and placed in the set position, and the conductive pins are inserted into the conductive fixing parts to complete the positioning connection and conductive mating.

[0008] Regarding the method of retaining conductive pins at the output end of the PCB board, those skilled in the art can adjust the die shape or cutting path according to the principle of the above technical solution to avoid the output area of ​​the PCB board. This improved design does not require creative effort. Regarding the production and assembly process of the pins, refer to existing technical information, such as the Chinese invention patent "Fully Automatic Pin Insertion Machine for PCB Board" with authorization announcement number CN102724816B. Regarding how the pins are arranged to form the circuit on the PCB board, this is existing technology and not an innovation of this solution, so it will not be elaborated here.

[0009] In one possible implementation, the output end of the PCB board extends with four conductive pins penetrating the housing, and the LED board is provided with four conductive fasteners that are respectively interference-fitted with the four conductive pins; the positive and negative output terminals of the PCB board are each assigned two conductive pins to form a stable conductive connection between the PCB board and the LED board.

[0010] In one possible implementation, the terminal block is exposed on the upper surface of the driver, and the conductive pin extends toward the bottom of the driver and passes through a removable base plate at the lower end of the housing; the terminal block is exposed on the upper surface of the driver (the side away from the conductive pin) to facilitate wiring after the driver is assembled with the LED light board, and the housing is provided with a removable base plate to facilitate the machining of through holes for the conductive pin to extend out on the base plate.

[0011] In one possible implementation, the upper surface of the driver is provided with wiring terminals and adjustment switches. The wiring terminals include push-button terminals, and the adjustment switches include color temperature adjustment switches and power adjustment switches. The conductive pins extend toward the bottom of the driver and penetrate the bottom surface of the housing. The wiring terminals and adjustment switches are located on the upper surface of the driver (the side away from the conductive pins), which facilitates wiring after the driver is assembled with the LED light board and makes it easy to adjust the state of the LED lights.

[0012] In one possible implementation, the conductive fastener includes a connector that is conductively welded to the LED light panel, and two clamping portions extending downward from both ends of the connector and approaching each other. The two clamping portions have notches on their approaching sides, and the notches of the two clamping portions are arranged opposite each other to form a jaw. The conductive pin passes through the jaw and is interference-fitted with the conductive fastener. The term "conductive welding" refers to welding with conductive materials, such as solder.

[0013] Furthermore, the connecting seat includes a first connecting seat and a second connecting seat located at its two transverse ends, and a U-shaped connector connecting the first connecting seat and the second connecting seat. The two clamping parts are integrally connected to the first connecting seat and the second connecting seat, respectively. The first connecting seat and the second connecting seat are integrally connected through the U-shaped connector. The U-shaped connector is provided on both longitudinal sides of the clamping part. While the U-shaped connector plays a connecting role, it also gives the conductive fixing part itself a certain elasticity. When the conductive pin is inserted into the jaws, it is interference-fitted with the jaws. The two clamping parts press against the conductive pin. The elasticity of the conductive fixing part itself can maintain this pressing tendency and ensure the stability of the conductive engagement.

[0014] This utility model also provides an LED lamp, including a lamp base, a lamp cover, a reflector installed between the lamp base and the lamp cover, and a light-emitting component of the LED lamp as described above; the driver is located on the upper surface of the reflector, the LED lamp board is installed on the lower surface of the reflector, the reflector is provided with a clearance hole, and the conductive pin passes through the clearance hole and is conductively inserted into the conductive fixing member; during assembly, a robotic arm is used to pick up the driver to the set position, the conductive pin is aligned with the conductive fixing member and inserted, after the conductive pin is inserted and positioned with the conductive fixing member, the driver and the LED lamp board are respectively located on the upper and lower sides of the reflector (the LED lamp board faces the lamp cover to achieve illumination), the driver, the LED lamp board, and the reflector are initially positioned and combined to form a light-emitting component with a driver, and are assembled together between the lamp base and the lamp cover.

[0015] In one possible implementation, the driver and the reflector are positioned and engaged by an auxiliary positioning component, which includes an auxiliary positioning protrusion and an auxiliary positioning hole / slot. When the auxiliary positioning protrusion is positioned and engaged with the auxiliary positioning hole / slot, the conductive pin is conductively inserted into the conductive fixing member.

[0016] In one possible implementation, the housing is provided with a plurality of insertion protrusions, and the reflector is provided with a plurality of positioning holes that engage with the insertion protrusions; while the conductive pin is inserted and positioned with the conductive fixing component, the insertion protrusion is inserted and positioned with the positioning holes, so that the driver and the reflector are mutually limited to prevent shaking; the insertion protrusions and positioning holes also serve to calibrate the orientation: after the robotic arm picks up the driver, it moves it accurately above the reflector. When the plurality of insertion protrusions and the plurality of positioning holes are completely aligned, it can be determined that the conductive pin can pass through the clearance hole and engage with the conductive fixing component.

[0017] In one possible implementation, the housing is provided with a snap-fit ​​protrusion, and the reflector is provided with a snap-fit ​​hole that engages with the snap-fit ​​protrusion; while the conductive pin is inserted and positioned with the conductive fixing component, the snap-fit ​​protrusion engages with the snap-fit ​​hole, and the snap-fit ​​protrusion and the snap-fit ​​hole connect the driver to the reflector, further ensuring the stability of the conductive connection between the driver and the LED light board.

[0018] In one possible implementation, the lower surface of the reflector extends with limiting claws, the limiting claws including a first limiting claw and a second limiting claw extending from both sides of the LED light panel to the lower surface of the LED light panel respectively; the first limiting claw and the second limiting claw position the LED light panel, thereby facilitating the driver to align with the LED light panel.

Those skilled in the art can make adjustments as needed to adapt to specific application scenarios.

[0022] In the description of the embodiments of this application, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium.

[0024] To make the objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments are described in detail below with reference to the accompanying drawings.

[0025] Example 1 like Figures 1 to 5As shown, this embodiment provides a light-emitting component for an LED lamp, including an LED lamp board 5 and a driver 4. The driver 4 includes a housing 43, a terminal block 41, and a PCB board 44 disposed within the housing 43. The input end of the PCB board 44 is electrically connected to the terminal block 41, and the output end of the PCB board 44 extends with a conductive pin 421 that penetrates the housing 43. The LED lamp board 5 is provided with a conductive fixing member 51, and the conductive pin 421 is conductively inserted into the conductive fixing member 51.

[0026] After production, the conductive pins 421 on the PCB board 44 need to be uniformly cut off the excessively long parts using a die (commonly known as "pin trimming") to avoid short circuits caused by contact between the pins and to improve aesthetics. This solution breaks through the conventional processing approach by retaining the conductive pins at the output end of the PCB board without cutting them off. In this embodiment, the die used for cutting the pins is adjusted during production to retain the conductive pins 421 at the output end of the PCB board 44 without cutting them off, and they are directly used as the conductive structure connecting the PCB board 44 and the LED light board 5, saving production steps and materials and reducing production costs. Regarding the adjustment method of the die, those skilled in the art can adjust the shape of the die or the cutting path according to the principle of the above technical solution to avoid the output area of ​​the PCB board. This adjustment does not require creative labor.

[0027] Furthermore, in this embodiment, the output end of the PCB board 44 extends with four conductive pins 421 that penetrate the housing 43, and the LED light board 5 is provided with four conductive fixing members 51 that are conductively connected to the four conductive pins 421 respectively; the positive and negative output terminals of the PCB board 44 are each assigned two conductive pins 421 so that the PCB board 44 and the LED light board form a stable conductive connection.

[0028] Furthermore, the terminal block 41 is exposed on the upper surface of the driver 4, and the conductive pin 421 extends toward the bottom of the driver 4 and passes through the removable base plate 42 at the lower end of the housing 43; the terminal block is exposed on the upper surface of the driver (the side away from the conductive pin), which facilitates wiring after the driver is assembled with the LED light board. The housing is provided with a removable base plate, which facilitates the machining of through holes for the conductive pin to extend on the base plate.

[0029] Furthermore, the upper surface of the driver 4 is provided with a wiring terminal 41 and an adjustment switch 45. The wiring terminal 41 includes a push-button type wiring terminal, and the adjustment switch 45 includes a color temperature adjustment switch and a power adjustment switch. The conductive pin 421 extends towards the bottom of the driver 4 and penetrates the bottom surface of the housing 43. The wiring terminal 41 and the adjustment switch 45 are located on the upper surface of the driver (the side away from the conductive pin), which facilitates wiring after the driver is assembled with the LED light board and makes it easy to adjust the state of the LED light.

[0030] Based on the above, the conductive fixing member 51 includes a connector 511 conductively welded to the LED light board 5, and two clamping portions 512 extending downward from both ends of the connector 511 and approaching each other. The two clamping portions 512 are provided with notches on the side that approaches each other, and the notches of the two clamping portions 512 are arranged opposite to each other to form a jaw 513. The conductive pin 421 passes through the jaw 513 and is interference-fitted with the conductive fixing member 51. In this embodiment, the "conductive welding" is tin soldering. Figure 5 The middle arrow indicates the insertion path of the conductive pin 421.

[0031] Specifically, the connecting seat 511 includes a first connecting seat and a second connecting seat located at its two transverse ends, and a U-shaped connector 514 connecting the first connecting seat and the second connecting seat. The U-shaped connector 514 arches downward, and two clamping parts 512 are integrally connected to the first connecting seat and the second connecting seat, respectively. The first connecting seat and the second connecting seat are integrally connected through the U-shaped connector 514. The U-shaped connector 514 is provided on both longitudinal sides of the clamping part 512. While the U-shaped connector 514 plays a connecting role, it also makes the conductive fixing part 51 itself have a certain elasticity. When the conductive pin 421 is inserted into the jaw 513, it is interference-fitted with the jaw 513. The two clamping parts 512 press against the conductive pin, and the elasticity of the conductive fixing part 51 itself can maintain this pressing tendency, ensuring the stability of the conductive engagement.

[0032] Example 2 like Figures 6 to 8 As shown, this embodiment provides an LED lamp, including a lamp base 1, a lamp cover 2, a reflector 3 installed between the lamp base 1 and the lamp cover 2, and also includes the light-emitting component of the LED lamp provided in Embodiment 1; the driver 4 is located on the upper surface of the reflector 3, the LED light board 5 is located on the lower surface of the reflector 3, the reflector 3 is provided with a clearance hole 32, and the conductive pin 421 passes through the clearance hole 32 and is conductively inserted into the conductive fixing member 51. During assembly, a robotic arm is used to grip the driver 4 to the set position, and then the conductive pin 421 is aligned with the conductive fixing member 51 and inserted. After the conductive pin 421 is inserted and positioned with the conductive fixing member 51, the driver 4 and the LED light board 5 are located on the upper and lower sides of the reflector 3 respectively (the LED light board 5 faces the lamp cover 2 to provide illumination). The driver 4, the LED light board 5, and the reflector 3 are initially positioned and combined to form a light-emitting component with a driver, and are assembled together between the lamp base 1 and the lamp cover 2.

[0033] Furthermore, the housing 43 is provided with a plurality of insertion protrusions 432, and the reflector 3 is provided with a plurality of positioning holes 312 that engage with the insertion protrusions 432; while the conductive pin 421 is inserted and positioned with the conductive fixing member 51, the insertion protrusions 432 are inserted and positioned with the positioning holes 312, so that the driver 4 and the reflector 3 are mutually limited to prevent shaking; the insertion protrusions 432 and the positioning holes 312 also play a role in orientation calibration: after the robot arm picks up the driver 4, it moves it accurately above the reflector 3. When the plurality of insertion protrusions 432 and the plurality of positioning holes 312 are completely aligned, it can be determined that the conductive pin 421 can pass through the clearance hole and engage with the conductive fixing member 51.

[0034] Furthermore, the housing 43 is provided with a snap-fit ​​protrusion 431, and the reflector 33 is provided with a snap-fit ​​hole 311 that engages with the snap-fit ​​protrusion 431. While the conductive pin 421 is inserted and positioned with the conductive fixing member 51, the snap-fit ​​protrusion 431 engages with the snap-fit ​​hole. The snap-fit ​​protrusion 431 and the snap-fit ​​hole connect the driver 4 to the reflector 3, further ensuring the stability of the conductive connection between the driver 4 and the LED light board 5.

[0035] Furthermore, the lower surface of the reflector 33 extends a limiting claw 313, which includes a first limiting claw and a second limiting claw extending from both sides of the LED light panel 5 to the lower surface of the LED light panel 5 respectively; the first limiting claw and the second limiting claw position the LED light panel 5, thereby facilitating the alignment of the driver 4 with the LED light panel 5.
