Description

Technical Field

[0001] This utility model belongs to the field of LED lamp bead technology, and in particular relates to a fracture-resistant two-electrode lamp bead bracket. Background Technology

[0002] Currently, 2835 LED chips are widely used and have become the preferred choice for fluorescent lamps, bulbs, panel lights, and other lighting fixtures in the LED industry. Lighting fixtures using 2835 chips appear more novel, unique, and attractive in the market, and their competitiveness is constantly increasing. With the widespread application of LEDs in lighting, market demand is growing, but the following problems exist: the leads of existing 2835 LED chip brackets are generally planar and thin. When used in highly flexible LED strips, these leads lack sufficient space and structural strength to accommodate the bending and twisting deformation of the strip, easily leading to lead breakage and even chip detachment, resulting in low product reliability. Utility Model Content

[0003] The purpose of this invention is to provide a fracture-resistant two-electrode lamp bead bracket to solve the problem of low reliability of lamp beads when used on highly flexible light strips.

[0004] To achieve the above objectives, this utility model provides a fracture-resistant two-electrode LED bead bracket, comprising an insulating bracket, a first electrode plate, and a second electrode plate. The first electrode plate and the second electrode plate are arranged at intervals on the same horizontal plane and are covered by the insulating bracket. The insulating bracket forms a dam on the upper surface of the first electrode plate and the second electrode plate, with the dam exposing portions of the first electrode plate and the second electrode plate. The first electrode plate extends out from one side of the insulating bracket to form a first electrode lead, and the extended portion of the first electrode lead is bent towards the bottom of the insulating bracket to form a first bend. The second electrode plate extends out from the other side of the insulating bracket. The second electrode pin is formed by extending outwards and bending towards the bottom of the insulating bracket to form a second bent portion. The bottom of the insulating bracket is provided with a first groove and a second groove. The first bent portion extends into the first groove and is separated from the groove wall of the first groove, and the second bent portion extends into the second groove and is separated from the groove wall of the second groove. Both the first electrode plate and the second electrode plate are provided with through holes penetrating their upper and lower surfaces. A portion of the through hole is filled with the insulating material of the insulating bracket, and the other portion of the through hole that is not filled with the insulating material of the insulating bracket is exposed outside the insulating bracket and communicates with the first groove or the second groove.

[0005] As a preferred embodiment of this utility model, the first bending portion and the second bending portion are the same size, and the first groove and the second groove are the same size.

[0006] As a preferred embodiment of this utility model, the first bending portion and the second bending portion are parallel to the lower surface of the insulating bracket.

[0007] As a preferred embodiment of this utility model, the first bending portion and the second bending portion are located at the same level.

[0008] As a preferred embodiment of the present invention, the lower surface of the first bent portion protrudes from the bottom of the insulating bracket; the lower surface of the second bent portion protrudes from the bottom of the insulating bracket.

[0009] As a preferred embodiment of this utility model, both sides of the first electrode plate and both sides of the second electrode plate are provided with recesses, and the recesses are completely filled by the insulating material of the insulating bracket.

[0010] As a preferred embodiment of this utility model, the inner circumferential surface of the dam is provided with a reflective surface that gradually increases in size from the inside out.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] This utility model's anti-fracture two-electrode LED bead bracket utilizes a bent section design to create a double-layer structure for the leads, enhancing their structural strength. Simultaneously, because the bent section is separate from and does not contact the groove at the bottom of the insulating bracket, during soldering, the wet solder can rise into the tiny gap between the bent section and the groove (this tiny gap, like a capillary, attracts the wet solder upwards through capillary action), effectively wetting the metal surface and achieving a good solder joint, thus improving the connection strength between the leads and the pads. Furthermore, through-holes are provided on the electrode plate, with a portion of the through-hole area being insulated by the insulating bracket. The insulation material filling improves the connection strength between the electrode plate and the insulating support. The other part of the through hole, which is not filled by the insulating material of the insulating support, is exposed outside the insulating support and communicates with the groove at the bottom of the insulating support. This design allows the wet solder to climb further into the through hole, forming a more robust connection structure. It can be seen that the anti-fracture wrapped two-electrode lamp bead bracket of this utility model has strong anti-fracture ability, enhances the stability and durability of the lamp bead bracket, and can effectively solve the problem of low reliability of lamp beads when used in highly flexible light strips, thereby reducing damage caused by bending, physical impact or thermal expansion of highly flexible light strips.

[0020] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0021] In the description of this utility model, it should be understood that the terms "upper", "lower", "left", "right", "front", "back", "top", "bottom", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0022] like Figures 1 to 4As shown in the preferred embodiment of this utility model, a fracture-resistant two-electrode lamp bead bracket includes an insulating bracket 1, a first electrode plate 2, and a second electrode plate 3. The first electrode plate 2 and the second electrode plate 3 are arranged at intervals on the same horizontal plane and are covered by the insulating bracket 1. The insulating bracket 1 forms a dam 11 on the upper surface of the first electrode plate 2 and the second electrode plate 3. The dam 11 exposes a portion of the surface of the first electrode plate 2 and a portion of the surface of the second electrode plate 3. The first electrode plate 2 extends out from one side of the insulating bracket 1 to form a first electrode lead 21. The extended portion of the first electrode lead 21 is bent toward the bottom of the insulating bracket 1 to form a first bend 22. The second electrode plate 3 extends out from the other side of the insulating bracket 1 to form a second electrode lead 22. The second electrode pin 31 has its extended portion bent towards the bottom of the insulating bracket 1 to form a second bent portion 32. The bottom of the insulating bracket 1 is provided with a first groove 12 and a second groove 13. The first bent portion 22 extends into the first groove 12 and is separated from the groove wall of the first groove 12. The second bent portion 32 extends into the second groove 13 and is separated from the groove wall of the second groove 13. Both the first electrode plate 2 and the second electrode plate 3 have through holes 4 penetrating their upper and lower surfaces. A portion of the through hole 4 is filled with the insulating material of the insulating bracket 1, and the other portion of the through hole 4 that is not filled with the insulating material of the insulating bracket 1 is exposed outside the insulating bracket 1 and communicates with the first groove 12 or the second groove 13.

[0023] Therefore, the anti-fracture lead-supported two-electrode LED bead bracket according to this utility model embodiment, through the design of the bending part, makes the lead form a double-layer structure to enhance the structural strength of the lead itself. At the same time, since the bending part is separate from and does not contact the groove at the bottom of the insulating bracket 1, when the LED bead is soldered, the wet solder can climb upward into the tiny gap between the bending part and the groove (this tiny gap, like a capillary, can attract the wet solder to climb upward under capillary action), which effectively wets the metal surface, thereby achieving a good solder joint and improving the connection strength between the lead and the pad; in addition, a through hole 4 is provided on the electrode plate, and part of the through hole 4 is insulated. The insulating material filling of the bracket 1 improves the connection strength between the electrode plate and the insulating bracket 1. The other part of the through hole 4, which is not filled by the insulating material of the insulating bracket 1, is exposed outside the insulating bracket 1 and communicates with the groove at the bottom of the insulating bracket 1. This design allows the wet solder to climb further into the through hole 4, forming a more robust connection structure. It can be seen that the anti-fracture two-electrode lamp bead bracket of this utility model has strong anti-fracture ability, enhances the stability and durability of the lamp bead bracket, and can effectively solve the problem of low reliability of lamp beads when used in highly flexible light strips, thereby reducing damage caused by bending, physical impact or thermal expansion of highly flexible light strips.

[0024] For example, in order to achieve a balanced and uniform amount of solder on the first electrode pin 21 and the second electrode pin 31, the first bend 22 and the second bend 32 are the same size, and the first groove 12 and the second groove 13 are the same size; the first bend 22 and the second bend 32 are parallel to the lower surface of the insulating bracket 1; the first bend 22 and the second bend 32 are located at the same level.

[0025] Furthermore, the lower surface of the first bending portion 22 protrudes from the bottom of the insulating bracket 1; the lower surface of the second bending portion 32 protrudes from the bottom of the insulating bracket 1, thereby forming an L-shaped support structure at the bottom of the lamp bead, effectively resisting damage to the lamp bead from impacts by external objects.

[0026] For example, recesses 5 are provided on both sides of the first electrode plate 2 and both sides of the second electrode plate 3. The recesses 5 are completely filled with the insulating material of the insulating bracket 1 to further improve the connection strength between the electrode plate and the insulating bracket 1.

[0027] For example, the inner circumferential surface of the dam 11 is provided with a reflective surface 14 that gradually increases in size from the inside to the outside, so that the side light of the light-emitting chip inside the dam 11 changes the illumination angle after passing through the reflective surface 14 of the dam 11, thereby improving the uniformity of illumination and the light energy utilization rate.

[0028] In the description of this utility model, 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; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0029] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
