[0026] Reference Figure 1 , a multi-chip retention arrangement structure is proposed,

[0027] A multi-chip retention arrangement structure, comprising a base 1, and at least one LED chip group 11 arranged on the base 1, characterized in that the LED chip group 11 comprises a plurality of primary chips 12 and a plurality of secondary chips 13, wherein the plurality of primary chips 12 are arranged at intervals along a first track line 2, and the plurality of secondary chips 13 are arranged at intervals along a second track line 3, and a single secondary chip 13 is opposite to the interval between two primary chips 12;

[0028] Connection ports are provided at both ends of the primary chip 12 and the secondary chip 13, and the connection ports include an N-level 122 and a P-level 121. The N-level 122 of the secondary chip 13 is connected to the P-level 121 of the primary chip 12, and the P-level 121 of the secondary chip 13 is connected to the N-level 122 of another primary chip 12.

[0029] This embodiment includes a plurality of LED chip groups 11, which are arranged on a base 1 and connected in series and parallel by metal wires. Starting from the power input, the current enters through the positive electrode and flows through each primary chip and secondary chip along the series path, and then returns through the negative electrode loop, thus forming a closed circuit.

[0030] The key to optimizing the "a" spacing is to maintain the symmetry between the chips at both ends of the base and the edges of their corresponding brackets. By ensuring the consistency of this spacing (ranging from 5-1500μm), the light output can be balanced along the axis of the entire light bar to prevent the light from deflecting to either end. This precise geometric positioning is conducive to maintaining the consistency of lighting effects under various installation conditions and ensuring the optimization of overall optical performance.

[0031] The "b" spacing refers to the spatial distance between individual chips, and its uniformity (ranging from 5-1000μm) is critical to achieving overall uniformity of light emission and heat dissipation. Equal spacing helps ensure that each LED chip receives the same amount of current and produces stable and consistent brightness. In addition, this also facilitates the uniform distribution of heat across the base, avoiding the occurrence of hot spots and improving the thermal efficiency and life of the entire LED light strip.

[0032] By reducing the spacing of the "c" interval and correspondingly increasing the spacing of the "d" interval, this design strategy expands the distribution range of the chips on the substrate, thereby optimizing the heat dissipation path. A wider distribution of chips means a larger surface area involved in heat exchange, which improves the heat dissipation efficiency, which is crucial for maintaining the LED operating temperature within the optimal range, and can significantly improve the performance stability of the LED light strip and reduce light decay.

[0033] The above technical solution significantly improves the uniformity of light and heat dissipation efficiency. This optimized arrangement not only makes the lighting effect smoother and has no obvious dark areas, but also greatly improves the working stability of LEDs and prolongs their lifespan. In addition, more effective heat dissipation management reduces energy loss, thereby improving energy efficiency and reducing use costs.

[0034] It should also be noted that in addition to the standard straight track line, a variety of track line designs can be used, such as circular, wavy or custom graphics, to suit different lighting needs and design aesthetics. This flexibility allows for more optical and thermal management solutions that can optimize the layout of LED chips for specific applications. For example, circular tracks can be used to create evenly distributed ring lighting, while wavy or curved tracks can provide more interesting visual effects and wider heat distribution. Regardless of the shape of the track line, the key is to ensure that each LED chip can be effectively connected and laid out to achieve optimal performance and optical properties.

[0035] Furthermore, the secondary chip 13 is connected to the primary chip 12 by metal wires.

[0036] The main advantage of using wire to connect the secondary chip and the primary chip is that it provides a stable electrical connection, ensuring that the current flows smoothly through the chip, which not only improves the electrical stability but also optimizes the lighting effect of the LED light strip. The elasticity and conductivity of the wire also facilitate flexible design, so that the distance between the chips in the LED light strip can be adjusted as needed, which is essential for uniform light distribution and effective heat dissipation. In addition, this connection method can enhance the maintainability and reliability of the light strip because it allows the entire light strip to continue to work even if individual LED chips fail.

[0037] As an alternative to wire, conductive adhesives or solder pastes can be used to establish connections between chips. These materials can provide similar electrical performance and heat dissipation characteristics, and may be easier to automate in some applications, speeding up the assembly process. In addition, printed conductive tracks on circuit boards are also a possibility, providing a structural connection method that can further integrate electronic components and simplify assembly.

[0038] Furthermore, the angle between the metal wire and the first track line 2 or the second track line 3 is in the range of 0-90°, and the first track line 2 is parallel to the second track line 3 .

[0039] The advantages of the 0-90° angle range between the metal wire and the track line and the parallel track line layout are that they provide optimized conductive paths and heat dissipation channels. By adjusting the angle of the metal wire, the current distribution and heat dissipation performance can be controlled to adapt to different usage environments and lighting requirements. In addition, the parallel track lines ensure consistent chip spacing, which is conducive to achieving uniform light output and improving the overall lighting effect. This design also helps to simplify the manufacturing process because the regular layout is easy to automate and improve production efficiency.

[0040] As an alternative, LED chips can be connected in a more flexible way, such as using bendable conductive materials or multi-layer printed circuit boards (PCBs) to achieve different shapes of track lines. For example, curved or spiral track lines can provide more diverse optical designs while potentially allowing for better heat dissipation performance. Through these innovative designs, customized solutions can be provided for specific product designs or lighting tasks while maintaining electrical stability and thermal management efficiency.

[0041] Furthermore, the LED chipset 11 also includes a first chipset 111, a second chipset 112 and a third chipset 113. The first chipset 111, the second chipset 112 and the third chipset 113 form two connection structures, namely a full-parallel structure and an N-parallel multi-string structure. The full-parallel structure includes a plurality of primary chips 12 and secondary chips 13. The primary chips 12 and the secondary chips 13 and the first chipset 111, the second chipset 112 and the third chipset 113 formed by the primary chips 12 and the secondary chips 13 are connected in parallel with each other. The N-parallel multi-string structure is a LED chipset 11 consisting of primary chips 12 and secondary chips 13 connected in series and connected in parallel.

[0042] The advantage of the full parallel and N-parallel multi-string connection structure composed of the first, second and third chip groups is that it provides a high degree of redundancy and current distribution flexibility. The full parallel connection ensures that even if one of the chip groups has a problem, the entire LED system can still work normally, thereby improving the reliability of the system. The N-parallel multi-string structure allows the current to be evenly distributed on multiple paths, reducing the current load on a single path, which is conducive to improving the service life of the chip and reducing the failure rate. In addition, this design can locally limit the loss when a part of the chip fails, keeping other parts working, which is very important in providing continuous lighting.

[0043] As an alternative to this structure, a modular design can be considered, in which each LED chipset is designed as a separately replaceable module. In this way, if a module fails, it can be quickly replaced without replacing the entire LED system, greatly simplifying maintenance and upgrades. In addition, using an intelligent drive circuit to dynamically adjust the current of each chipset is also a solution, which can intelligently distribute the current according to the performance and fault conditions of the chip, further improving the overall efficiency and life of the system.

[0044] Furthermore, isolation zones 14 are provided at opposite ends of the base 1 , and power ports 141 are provided on the isolation zones 14 . The primary chips 12 at both ends of the base 1 are spaced in the same distance from the isolation zones 14 , and the secondary chips 13 are spaced at equal distances from each other.

[0045] The design advantage of having isolation strips and power ports at both ends of the base is that it provides clear electrical definition and enhanced safety. The isolation strip acts as a physical and electrical barrier to help prevent short circuits and ensure safe operation of the LED chipset. At the same time, the presence of the power port allows current to flow into the LED chipset, while the ports set on the isolation strip facilitate external connections and maintenance. The consistent spacing between the primary chips and the isolation strip at both ends of the base and the equal spacing between the secondary chips help maintain a neat structure and improve the aesthetics of the product, while also helping to achieve a uniform distribution of light output.

[0046] As an alternative to this design, integrated ports and embedded isolation structures can be used. Such a design can reduce exposed wiring ports, further improving the overall durability and safety of the product. In addition, the use of flexible non-conductive materials as isolation strips can provide more freedom in shape and size in different product designs while maintaining the integrity and functionality of the circuit. This design allows customization and innovation based on application needs without sacrificing performance

[0047] When working, the primary chip and the secondary chip are arranged at intervals along parallel track lines through metal wires, and are connected to each other through P-level and N-level wiring ports to form a series-parallel circuit structure.

[0048] The utility model also provides an LED light bar, comprising the above-mentioned multi-chip retention arrangement structure. Since the LED light bar has the above-mentioned multi-chip retention arrangement structure, it also has the beneficial effects of the multi-chip retention arrangement structure.

[0049] The above is only used to illustrate the technical solution of the utility model rather than to limit it. Other modifications or equivalent substitutions made to the technical solution of the utility model by ordinary technicians in this field should be included in the scope of the claims of the utility model as long as they do not depart from the spirit and scope of the technical solution of the utility model.
