Description

Technical Field

[0001] This utility model relates to the field of LED light-emitting device manufacturing technology, and in particular to an LED bracket, LED beads and an outdoor display screen. Background Technology

[0002] LED brackets are the core components that support LED chips and enable circuit connections. Their performance directly affects the stability and lifespan of the LED chips. Outdoor displays, composed of LED chips, are large-scale display devices widely used in plazas, commercial districts, transportation hubs, and other scenarios, placing stringent requirements on the reliability of their core components. Outdoor displays are exposed to the natural environment for extended periods, needing to withstand alternating high and low temperatures, wind and rain erosion, vibration, and impact. This makes the structural stability and protective performance of the LED brackets, as the basic framework, a key factor determining the overall lifespan and display effect of the outdoor display.

[0003] Currently, some LED brackets have relatively smooth surfaces on the tensioned parts of their functional components, resulting in poor interlocking and weak bonding between them and the PPA material. During LED device use, especially in complex outdoor environments, frequent temperature changes and external vibrations can easily cause the tensioned parts to separate or loosen from the PPA material. This not only compromises the overall structural stability of the device but also reduces its airtightness, allowing moisture and other external contaminants to easily penetrate, affecting the normal operation of the LED chip. This leads to decreased luminous efficiency, shortened lifespan, and in severe cases, even device failure, failing to meet the high reliability requirements of applications such as outdoor displays.

[0004] Therefore, there is an urgent need for an LED bracket that can solve the problem of poor bonding between functional components and PPA (polyphthalamide), and improve the structural stability and airtightness of the LED bracket. Utility Model Content

[0005] The purpose of this invention is to provide an LED bracket that can solve the problem of poor bonding between functional components and PPA, and improve the structural stability and airtightness of the LED bracket.

[0006] Based on the above concept, the technical solution adopted by this utility model is as follows:

The surface of the stretching part is provided with a resistance-increasing structure.

[0009] An external connector, one end of which is connected to the tensioning part, and the other end of which is connected to an external power supply structure.

[0010] As an optional solution for the LED bracket, the resistance-enhancing structure is a groove structure with alternating concave and convex shapes.

[0011] As an optional solution for the LED bracket, the functional component is provided in a pair, the pair of functional components are arranged opposite each other, and the stretching part and the extension part of the pair both extend inward.

[0012] As an optional solution for the LED bracket, the surface of the functional component is electroplated with an electroplating layer.

[0013] As an alternative to the LED bracket, the electroplating layer of the stretch portion is made of nickel, and the electroplating layer of the extension portion is made of silver.

[0014] As an optional solution for the LED bracket, this functional component is made of copper alloy.

[0015] An LED bead includes an LED chip and an LED bracket. The LED chip is fixed to the surface of the extension away from the stretching portion, and the LED chip is electrically connected to the functional component.

[0016] As an optional solution for the LED lamp bead, the LED lamp bead also includes an encapsulating colloid that covers the LED chip and the portion of the extension near the LED chip.

[0017] As an optional solution for the LED bead, an annular groove is provided at the connection between the encapsulant and the functional component, and the annular groove is filled with sealant.

It should be understood that the specific embodiments described herein are merely for explaining this utility model and not for limiting it.

[0030] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0031] This utility model proposes an LED bracket, such as Figures 1-2 As shown, in this embodiment, the LED bracket includes a functional component 1 and an external connector. The functional component 1 is connected to the LED chip. The functional component 1 includes an integrally formed stretching part 11 and an extension part 12. The stretching part 11 extends upward, and the extension part 12 extends horizontally from the top of the stretching part 11. The surface of the stretching part 11 is provided with a resistance-increasing structure. One end of the external connector 2 is connected to the stretching part 11, and the other end is connected to an external power supply structure. By setting a resistance-increasing structure in the stretching part 11 of the functional component 1, the stretching part 11 can be better fitted with the PPA material. This not only enhances the bonding force between the two and effectively prevents separation or loosening due to factors such as stress and temperature changes during subsequent use, but also improves the overall airtightness. As a result, it has advantages in structural stability and reliability, and can better adapt to various usage environments, even more complex ones.

[0032] Preferably, such as Figures 1-2 As shown, in this embodiment, the resistance-enhancing structure is an alternating concave-convex groove structure, which can form a tighter fit with the PPA material through the grooves, significantly increasing the contact area and interlocking force between the two, further strengthening the bonding force between the tension part 11 and the PPA material, and more effectively resisting the risk of separation or loosening caused by stress and temperature changes. At the same time, the concave-convex structure can enhance the overall airtightness like sealing teeth, making the LED bracket more superior in terms of structural stability and reliability, and more easily able to cope with various complex usage environments.

[0033] Preferably, such as Figures 1-2 As shown, in this embodiment, a pair of functional components 1 are provided, with the pair of functional components 1 arranged opposite to each other. The pair of tensioning parts 11 and extension parts 12 both extend inward, which enables the two functional components 1 to cooperate more precisely to fix the LED chip, so that the chip is in a symmetrical and stable support environment. This not only improves the convenience and positioning accuracy of LED chip installation, but also disperses the force through the symmetrical structure, reducing deformation or loosening caused by excessive force on one side. At the same time, the inward extension design can shorten the current transmission path, reduce energy consumption, and enhance the overall structural stability, thereby further improving the reliability and performance of the LED bracket in complex environments.

[0034] Specifically, such as Figures 1-2 As shown, in this embodiment, the surface of functional component 1 is electroplated with an electroplating layer, which can significantly improve its conductivity, ensure stable and efficient current transmission between the LED chip and the external power supply structure, and reduce energy consumption. At the same time, the electroplating layer can enhance the corrosion resistance and wear resistance of functional component 1, slow down its aging rate in complex environments, extend its service life, and further ensure the stability and reliability of the overall structure of the LED bracket.

[0035] Preferably, in this embodiment, the electroplated layer of the stretching portion 11 is made of metallic nickel, and the electroplated layer of the extension portion 12 includes two layers: an inner layer made of metallic nickel and an outer layer made of metallic silver. The stretching portion 11 is electroplated with metallic nickel, which, due to its strong corrosion resistance, reduces the possibility of chemical reactions with air components in complex environments, thus extending the service life of the stretching portion 11. At the same time, the fact that the stretching portion 11 is only plated with a nickel layer reduces the electroplating area of ​​the silver layer, significantly reducing material costs. Through appropriate surface treatment processes, such as roughening treatment or chemical modification, the electroplated metallic nickel of the stretching portion 11 can also form a more stable bond with the PPA material, further strengthening the interlocking effect between the stretching portion 11 and the PPA, and effectively preventing the stretching portion 11 from separating or loosening from the PPA.

[0036] Preferably, in this embodiment, functional component 1 is made of copper alloy. The excellent conductivity of copper alloy ensures stable and efficient current transmission between the LED chip and external components, reducing power loss. The good thermal conductivity of copper alloy quickly dissipates the heat generated by the LED chip during operation, preventing overheating from affecting performance and lifespan. Simultaneously, copper alloy possesses high strength and ductility, meeting the stretching and elongation processing requirements of the integrally formed functional component 1, ensuring the structural stability of the stretching portion 11 and the elongation portion 12. Furthermore, in conjunction with the resistance-enhancing structure, it further enhances the integration effect with the PPA material, improving the durability and reliability of the overall bracket in complex environments, giving the LED bracket greater advantages in conductivity, heat dissipation, and structural strength. In other embodiments, functional component 1 can also be made of iron alloy or aluminum alloy, etc.

[0037] This utility model also proposes an LED lamp bead. In this embodiment, the LED lamp bead includes an LED chip and an LED bracket. The LED chip is fixed to the surface of the extension 12 away from the stretching part 11, and the LED chip is electrically connected to the functional component 1. The functional component 1 can realize stable current transmission and ensure that the LED chip emits light normally. At the same time, the LED bracket can provide stable support and effective heat dissipation for the LED chip, reduce failures caused by stress, temperature changes, etc., improve the structural stability and reliability of the lamp bead, enable it to better adapt to various environments, and extend its service life.

[0038] Specifically, in this embodiment, the LED bead also includes an encapsulating colloid. The encapsulating colloid covers the LED chip and the portion of the extension 12 near the LED chip, providing physical protection for the LED chip, isolating it from external dust, moisture, and mechanical impact, and preventing chip damage. At the same time, the encapsulating colloid can fix the connection between the chip and the extension 12, enhancing structural stability. Combined with the design of the bracket's resistance-increasing structure, it further improves overall reliability. Furthermore, by selecting a suitable colloid material, it can optimize light output and reduce light loss, allowing the LED bead to maintain stable light emission while having a longer service life and better optical performance, thus better adapting to complex usage environments.

[0039] Preferably, in this embodiment, an annular groove is provided at the connection between the encapsulating colloid and the functional component 1. The annular groove is filled with sealant, which can further enhance the sealing between the encapsulating colloid and the functional component 1. The structural design of the annular groove increases the filling space and contact area of ​​the sealant, so that the sealant is tightly bonded to both, effectively preventing moisture and other substances from entering from the connection, and avoiding damage to the LED chip due to moisture and contamination. At the same time, this double sealing structure, combined with the protective function of the encapsulating colloid itself, can greatly improve the LED bead's resistance to environmental interference and reduce failures caused by sealing failure. Combined with the stable structure of the bracket and the excellent performance of the functional component 1, the reliability and service life of the LED bead in complex environments are further guaranteed, ensuring its long-term stable light emission.

[0040] This utility model also proposes an outdoor display screen, which includes a mounting frame and LED beads. The mounting frame includes a frame and a grid bracket. The frame surrounds and forms a mounting cavity. The grid bracket is horizontally fixed in the mounting cavity and arranged in an array. The LED beads are fixed to the grid nodes of the grid bracket by a snap-fit ​​structure. The spacing between adjacent LED beads is equal. The surface of the mounting frame is coated with an anti-corrosion coating. By fixing the LED beads to the grid nodes of the grid bracket with the snap-fit ​​structure and the equal spacing between adjacent beads, a uniform display image can be formed, ensuring the consistency of the display effect. The frame and grid bracket of the mounting frame provide stable support, and the snap-fit ​​structure facilitates the installation and maintenance of the LED beads. The anti-corrosion coating on the surface of the frame can resist outdoor wind, rain, ultraviolet rays and other corrosion, extending the service life of the display screen. At the same time, the structural stability, good sealing and reliability of the LED beads themselves enable them to work stably in complex outdoor environments. This allows the entire outdoor display screen to have a clear and uniform display effect, strong environmental adaptability and durability, easy installation and maintenance and a long service life.
