Description
Technical Field
[0001] This utility model belongs to the technical field of LED lighting fixtures and accessories, and in particular relates to an LED chip assembly. Background Technology
[0002] Surface mount LED chips are currently the most common type of LED lighting fixture. They are widely used due to their small size, long lifespan, ease of replacement, and wide applicability. Surface mount LED chips consist of two parts: LED chips, a chip, conductive contacts, and a surface mount assembly. The LED chips are mounted on the chip, and the surface mount assembly is located on the other side of the chip. The chip is then attached to the surface of the circuit board via the surface mount assembly, and the conductive contacts on the chip are connected to the circuit board, thus enabling power supply and control of the surface mount LED chips.
[0003] Chinese patent application CN219036480U discloses an LED chip assembly, including an LED board. The LED board has a conductor in the middle, and a set of power-contact points evenly distributed on its top, connected to the conductor. LED chips are soldered onto the LED board. A pin is located at the right end of the LED board, and a slot is formed at the left end. A heat dissipation layer is adhered to the bottom of the LED board, and a double-sided adhesive layer is adhered to the bottom of the heat dissipation layer. The advantages of this invention are: it facilitates the splicing of multiple LED boards; the pin of one LED board is inserted into the inner wall of the slot of another board and connected to a groove block; the protrusion and locking point connect to position the pin.
[0004] The aforementioned LED chip assembly has slots and pins at both ends of the LED board. The pins of one set of LED boards are inserted into the inner wall of the slot of another set and connected to a recessed block. The protrusions and locking points position the pins, thus enabling the splicing of two or more sets of LED boards. However, relying solely on the convex structure of the protrusions and locking points results in unstable contact between them, making it easy for the assembled LED boards to detach. Furthermore, the LED board has a first electrical contact point, and the LED chip has a second electrical contact point. During assembly, the second electrical contact point on the LED chip is connected to the first electrical contact point, and the LED chip is fixed to the LED board by welding. This connection method still results in the inability to replace damaged individual chips due to the welding connection, rendering the entire LED board and its chips unusable. This leads to the waste of resources as the entire LED board must be replaced. To address these issues, we provide an LED chip assembly. Utility Model Content

Both ends of the shaft are equipped with return springs, and the shaft is connected to the shaft hole through the return springs. The lower side wall of the arc-shaped plate is spaced apart from the upper side wall of the ring, and the ring is fixedly disposed in the upper side wall of the insertion hole three.
[0015] This utility model has the following beneficial effects:
[0016] 1. This utility model comprises a lamp panel, a connecting component, and a fixing component. The lamp panel has connecting components at both ends, including connecting plates and plug-in plates respectively installed at both ends of the lamp panel. Multiple lamp panels can be assembled together through the plug-in connection between the connecting plates and plug-in plates. The connecting plates and plug-in plates each have a first plug-in hole and a second plug-in hole. The connecting plate also has a fixing component, which includes a fixing ring located outside the first plug-in hole on the connecting plate. A sliding pin is slidably inserted into the first plug-in hole inside the fixing ring. A traction spring is sleeved on the outside of the sliding pin, and a pull ring is fixedly installed on the upper end of the sliding pin. One end of the traction spring is connected to the fixing ring. One end is connected to a pull ring. In use, align the plug plate on one light panel with the connecting plate on another light panel, and push the plug plate to insert it into the connecting plate. While pushing the plug, hold the pull ring and pull it upwards. The traction spring is pulled upwards, and the sliding pin disengages from the first insertion hole on the connecting plate. At this point, the plug plate can be fully inserted into the connecting plate. After the plug plate is fully inserted into the connecting plate, release the pull ring. The traction spring returns to its initial state, pulling the pull ring downwards. As the pull ring moves downwards, the sliding pin passes through the first insertion hole again and enters the second insertion hole on the plug plate, thus fixing the plug plate and the connecting plate.
[0017] 2. This utility model comprises a lamp plate, a limiting component, and a lamp bead assembly. The lamp plate has multiple mounting slots evenly spaced for lamp bead installation, and fixing holes are provided at the four corners of each slot.

A side groove is provided on the upper outer wall of the column, and a limiting component is provided within the side groove. The limiting component includes an arc-shaped plate within the side groove, with a shaft inserted into the upper end of the arc-shaped plate. Return springs are provided at both ends of the shaft, which is connected to the inner wall of the side groove via the return springs. The lamp bead assembly includes a lamp bead body mounted on a chip. Insertion holes are provided at the four corners of the chip. In use, the insertion holes on the chip are aligned with the columns on the lamp plate, and the lamp bead is pressed down. The column can then pass through the insertion holes. As the chip's insertion holes pass through the column, the insertion holes exert a certain pressure on the outer wall of the arc-shaped plate in the limiting component. This pressure will cause… The curved plate is compressed towards the column. As the curved plate moves, the shaft at its end also rotates. When the shaft rotates, the return spring at its end generates torque. When the third socket passes through the curved plate and enters the column below the curved plate, the curved plate disengages from the third socket, meaning it is freed from the compressive force. At this point, the return spring returns to its initial state, causing the shaft to rotate back to its original position. The curved plate then opens again and sits above the chip, preventing it from passing through the column again and detaching from the lamp board. When the lamp assembly needs to be replaced, first pinch the curved plate with your fingers and let it adhere to the outer wall of the column. Then lift the lamp body, which will move the chip upwards. The curved plate will then adhere to the outer wall of the column, and it will no longer obstruct the third socket on the chip. The third socket on the chip can then slide off the column, thus achieving the disassembly and replacement of the lamp assembly. Attached Figure Description

Detailed Implementation
[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0028] Example 1
[0029] Please see Figure 1-4 This utility model is an LED chip assembly, including a lamp board 1, a chip adhesive board 2, a connecting component 3 and a fixing component 4. The connecting component 3 enables multiple lamp boards 1 to be spliced together, and the fixing component 4 fixes the spliced lamp boards 1 to prevent them from falling off.
[0030] Specifically, a patch adhesive plate 2 is adhered to the bottom side wall of the lamp panel 1. The connecting assembly 3 includes a connecting plate 301 and a plug plate 302 respectively disposed at both ends of the lamp panel 1. The end of the connecting plate 301 is connected to the lamp panel 1 through a first connecting plate 301a, and the end of the plug plate 302 is connected to the lamp panel 1 through a second connecting plate 302a. The connecting plate 301 and the plug plate 302 are respectively provided with a first plug hole 301b and a second plug hole 302b.
[0031] Furthermore, the fixing component 4 includes a sliding insert post 401 that is slidably inserted into the insertion hole 301b, and a fixing ring 402 disposed on the outer side of the insertion hole 301b and on the upper side wall of the connecting plate 301. A pull ring 404 is also fixedly disposed at the upper end of the sliding insert post 401. A traction spring 403 is also sleeved on the outer wall of the sliding insert post 401. One end of the traction spring 403 is connected to the pull ring 404, and the other end is connected to the fixing ring 402.
[0032] The operation process of this embodiment is as follows: When in use, align the plug plate 302 on one lamp board 1 with the connecting plate 301 on another lamp board 1, and push the plug plate 302 to insert it into the connecting plate 301. While pushing the plug, you also need to hold the pull ring 404 and pull it upward. The traction spring 403 is pulled upward, and the sliding plug 401 disengages from the first insertion hole 301b on the connecting plate 301. At this time, the plug plate 302 can be fully inserted into the connecting plate 301. After the plug plate 302 is fully inserted into the connecting plate 301, release the pull ring 404. At this time, the traction spring 403 returns to its initial state, and then pulls the pull ring 404 downward. While the pull ring 404 moves downward, the sliding plug 401 passes through the first insertion hole 301b again and enters the second insertion hole 302b on the plug plate 302, thereby forming the effect of fixing the plug plate 302 and the connecting plate 301.
[0033] Example 2
[0034] Please see Figure 5-6 Based on embodiment 1, a limiting component 5 and an LED component 6 are also provided. The limiting component 5 can limit the LED component 6 assembled on the lamp board 1 to prevent it from automatically detaching from the lamp board 1, and at the same time, it can facilitate the disassembly and replacement of the LED component 6.
[0035] Specifically, the lamp panel 1 has multiple mounting slots 101 at equal intervals, and the four corners of the mounting slots 101 are also provided with fixing holes 102. The limiting component 5 includes a fixing plate 502 fixed in the fixing holes 102. A column 501 is fixedly installed on the upper side wall of the fixing plate 502. A side groove 501a is opened on the outer wall of the upper end of the column 501, and a limiting member 503 is provided in the side groove 501a.
[0036] Furthermore, the side grooves 501a and the limiting members 503 are arranged in a one-to-one correspondence. There are six side grooves 501a in total, arranged in a ring array. Shaft holes 501b are opened on the inner walls of both sides of the side grooves 501a. The limiting member 503 includes an arc-shaped plate 503a disposed in the side groove 501a, and a shaft 503b is inserted into the upper end of the arc-shaped plate 503a. Return springs 503c are installed at both ends of the shaft 503b. The shaft 503b is connected to the shaft hole 501b via a return spring 503c. The lamp bead assembly 6 includes a chip 601 disposed in the mounting groove 101. The chip 601 has three insertion holes 602 at its four corners for sliding and engaging with the column 501. A ring 602a is provided on the upper side wall of the insertion hole 602. The upper side wall of the ring 602a is separated from the bottom side wall of the arc plate 503a. The lamp bead body 603 is mounted on top of the chip 601.
[0037] The operation process of this embodiment is as follows: During use, the socket 602 on the chip 601 of the lamp bead body 603 is aligned with the column 501 in the upper limit assembly 5 of the lamp board 1, and the lamp bead body 603 is pressed down. At this time, the column 501 can pass through the socket 602. During the process of the socket 602 of the chip 601 passing through the column 501, the socket 602 will exert a certain pressure on the outer wall of the arc plate 503a in the limiting member 503. This pressure will cause the arc plate 503a to be compressed towards the column 501. When the arc plate 503a moves, the shaft 503b on its shaft end also rotates. When the shaft 503b rotates, the return spring 503c on its end generates torque. When the socket 602 passes through the arc plate 503a and enters the column 501 on the lower side of the arc plate 503a, the arc plate 503a disengages from the socket 602. 602, that is, the arc plate 503a is freed from the pressure. At this time, the return spring 503c returns to its initial state, thereby driving the shaft 503b to rotate and reset. Then, the arc plate 503a is once again opened and positioned above the chip 601, thus blocking the chip 601 from passing through the column 501 again and detaching from the lamp board 1. When it is necessary to replace the lamp bead assembly 6, first pinch the arc plate 503a with your fingers and make it adhere to the outer wall of the column 501. Then lift the lamp bead body 603, which will move the chip 601 upward. The arc plate 503a will then adhere to the outer wall of the column 501. At this time, the arc plate 503a will not block the socket 602 on the chip 601. Thus, the socket 602 on the chip 601 can slide off the column 501, thereby realizing the disassembly and replacement of the lamp bead assembly 6.
