For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood by specific circumstances.
[0031] like Figures 1 to 4 As shown, the embodiment of the present application provides a compact white light LED bracket, including a bracket body 1 and a first welding piece 2 and a second welding piece 3 arranged at the bottom of the bracket body 1, the first welding piece 2 and the second welding piece 3 are both provided with a limiting portion 4, the bracket body 1 is provided with a card slot 12, the first welding piece 2 and the second welding piece 3 are connected to the bracket body 1 through the buckling of the limiting portion 4 and the card slot 2;
[0032] The bracket body 1 is also provided with a receiving cavity 11 , and the first welding piece 2 and the second welding piece 3 are placed into the receiving cavity 11 through the bottom of the bracket body 1 , and the receiving cavity 11 is used to receive LED lamp beads.
[0033] In current technology, a common problem with traditional LED bracket design is that the pad occupies too large an area, resulting in the need to use a large amount of precious metals such as copper and silver during the production process, which not only increases raw material consumption but also limits the flexibility of product design.
[0034] The utility model effectively reduces the need for using precious metals such as copper and silver by designing the areas of the first welding part and the second welding part to be significantly smaller than the bottom area of the bracket body, so that the utility model can significantly reduce the proportion of hardware while ensuring the existing patch and conductive requirements.
[0035] At the same time, the snap-fit design of the limit part and the slot not only enhances the stability of the structure, but also further improves the efficiency of material use.
[0036] In this embodiment, a specific accommodating cavity is designed on the bracket body for directly accommodating the LED lamp beads. The existence of the accommodating cavity reduces the risk of the LED lamp beads being affected by external impacts or environmental factors, thereby extending the service life of the lamp beads. At the same time, this design also helps to optimize the light projection angle and distribution of the lamp beads, because the position of the lamp beads can be precisely controlled.
[0037] In addition, the interior of the accommodating cavity can be specially treated, such as adding a reflective coating, to enhance light efficiency and improve the light output performance of the entire device. Through this integrated design, the assembly of the entire LED module is simpler and faster, which improves production efficiency and is also easy to maintain and replace.
[0038] Specifically, the size of the first welding part and the second welding part is designed to be 1.28 mm x 1.10 mm, which is sufficient to meet the basic requirements of electrical connection while greatly reducing the use of precious metals. The area of the bottom of the entire bracket body is 1.77 mm x 1.24 mm, providing sufficient space to support the stability and durability of the structure.
[0039] Preferably, an aluminum alloy material with high conductivity but low cost is used to replace part of the copper foil to further reduce costs.
[0040] Alternatively, epoxy resin or other non-metallic conductive materials are used to fill the first welding part and the second welding part. Although the conductivity of such materials is slightly lower than that of metals, the cost is lower and the basic electrical requirements can be met through design adjustments.
[0041] Optionally, the limiting portion 4 includes a longitudinal side 41, a main outer contour side 42 and a reference outer contour side 43, the longitudinal side 41 is located on the right side of the limiting portion 4, the longitudinal side 41 is perpendicular to the bottom of the bracket body 1, the main outer contour side 42 is located above the limiting portion 4, the main outer contour side 42 forms an angle with the bottom of the bracket body 1, the reference outer contour side 43 is located below the limiting portion 4, and the reference outer contour side 43 is snap-fitted with the slot 12.
[0042] In this embodiment, the design of the compact white light LED bracket includes a precisely configured limit portion, which enhances the stability and durability of the overall structure. The limit portion is composed of a longitudinal side, a main outer contour side and a reference outer contour side. This structural design optimizes the mechanical locking of the component, ensuring a stable structural connection during long-term use, while facilitating the assembly process and improving production efficiency.
[0043] Specifically, the main outer contour side 42 is located above the limiting portion 4, referring to Figure 2 The main outer contour side 42 has a slope for promoting smooth engagement between the component and the bracket body. The main outer contour side is made of wear-resistant material or surface-treated to enhance its corrosion resistance and durability, ensuring that its structural and functional integrity is maintained during long-term use.
[0044] The longitudinal side is located on the right side of the limiter 4, serving as the main structural support to enhance the overall stability of the component. Figure 2 , the longitudinal side exists in an upright form, and its main function is to provide sufficient structural strength to withstand loads and stresses under various operating conditions.
[0045] The side of the reference outer contour is located below the limiting portion 4 , and the side of the reference outer contour is a flat structure with rectangular corners.
[0046] Optionally, the main outer contour side 42 and the bottom of the bracket body 1 form an angle of 15-80 degrees.
[0047] In this embodiment, the 15 to 80 degree angle design formed by the main outer contour side and the bottom of the bracket body optimizes the assembly efficiency and mechanical stability of the components. The 15 to 80 degree angle enables the components to be more easily docked with adjacent components, while improving the contact quality of the joint surface, thereby reducing stress concentration and enhancing the structural integrity and durability of the entire device, which has a significant effect on improving production efficiency and reducing maintenance requirements.
[0048] Optionally, the first welding member 2 is further provided with a first stamping portion 21 , and the second welding member 3 is further provided with a second stamping portion 31 , and the first stamping portion 21 and the second stamping portion 31 are flattened by punching to form a protrusion.
[0049] In this embodiment, the first welding part and the second welding part are respectively provided with a first stamping part and a second stamping part that have been punched and flattened to form a raised structure. The raised stamping part can significantly increase the contact area of the solder joint, thereby improving the mechanical strength and electrical reliability of the welding. The protrusions that have been flattened by punching can also help increase the heat dissipation area of the welding part, optimize thermal management, and reduce electrical failures caused by overheating.
[0050] Optionally, the number of the first stamping part 21 and the number of the second stamping part 31 are two respectively.
[0051] In this embodiment, two stamping parts are designed on each welding part, that is, the first welding part and the second welding part have two first stamping parts and two second stamping parts respectively. By increasing the number of stamping parts, the structural stability of the welding point and the reliability of the electrical connection are significantly improved: multiple stamping parts can evenly distribute the welding pressure and heat, avoid the risk of single-point overload, and thus reduce potential welding failures.
[0052] In addition, the multi-stamping design also helps to improve current distribution and enhance the overall electrical performance of the LED bracket. It not only enhances the durability of welding, but also increases assembly flexibility and adjustment space by providing more contact points, making the entire LED bracket more reliable and efficient.
[0053] Optionally, the first welding member 2 and the second welding member 3 are both made of copper foil, and serve as the positive electrode and the negative electrode of the LED lamp bead respectively.
[0054] In this embodiment, the first welding part and the second welding part are both made of copper foil, which are respectively connected to the positive and negative poles of the LED lamp bead, which can effectively reduce resistance, improve current transmission efficiency, and ensure that the LED lamp bead can receive a stable and efficient power supply.
[0055] In addition, the flexibility and plasticity of copper foil allow the welding part to be precisely adapted to the contact point of the LED lamp bead, enhancing the reliability and durability of welding. By using copper foil as the connecting material, it not only improves the performance of the electrical connection, but also helps to extend the service life of the entire LED device and reduce maintenance costs caused by electrical failures.
[0056] Optionally, the bracket body 1 is 3-3.4 cm long and 2.5-2.8 cm wide, the first welding part 2 is 1.6-1.8 cm long and has a width range of 1.01-1.35 cm, and the second welding part 3 is 1.2-1.5 cm long and has a width range of 1.01-1.35 cm.
[0057] Optionally, the areas of the first welding part 2 and the second welding part 3 are less than or equal to half of the bottom area of the bracket body 1 .
[0058] In this embodiment, by designing the area of the first welding part and the second welding part to be less than or equal to half of the bottom area of the bracket body, the required amount of solder and precious metal materials is effectively reduced, thereby reducing production costs. At the same time, this design optimizes the layout of the solder joints, ensures the stability of the connection and the long-term reliability of the product, and meets the dual needs of cost-effectiveness and product performance in industrial production.
[0059] Optionally, the copper foil surfaces of the first welding member 2 and the second welding member 3 are tin-plated.
[0060] In this embodiment, the copper foil surfaces of the first welding part and the second welding part are tin-plated, which significantly improves the solderability and corrosion resistance of the welding interface: the tin-plated copper foil surface can reduce oxidation and prevent corrosion of the copper foil surface during long-term use, thereby maintaining good electrical conductivity. At the same time, the tin layer can also reduce the joining temperature between the copper foil and the solder, making the welding process easier and more stable, and improving production efficiency and welding quality.
[0061] In addition, tin plating also increases the mechanical strength of the solder joints and improves the fatigue resistance of the connections, thereby ensuring the reliability and durability of the electrical connections during long-term operation of the LED lamp beads. These improvements not only optimize the performance of the product, but also extend the overall life of the LED equipment and reduce maintenance requirements and costs.

The same components are represented by the same figure marks. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
