DETAILED DESCRIPTION

[0026] The present invention provides an LED lamp bead patch bracket and an LED lamp bead. To make the purpose, technical solution, and effects of the present invention more clear and explicit, the present invention is further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely for the purpose of explaining the present invention and are not intended to limit the present invention.

It should also be understood that terms such as those defined in general dictionaries should be understood to have meanings consistent with their meanings in the context of the prior art, and will not be interpreted in an idealized or overly formal sense unless specifically defined as herein.

[0030] In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the fact that ordinary technicians in this field can implement them. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by this utility model.

[0031] The inventors discovered that existing LED lamp holders typically utilize two layers of stamped copper, which are then encased in plastic for airtightness. Specifically, the holder is formed using a stamped layered design around the perimeter, with the long sides inserted into the plastic to provide airtight protection within the lamp. This effectively blocks harmful elements from entering through the gap between the plastic and copper. Stamped waterproof grooves are also used on both sides of the test pins for airtightness protection. However, when the LED lamp lights up and heats up, causing the plastic holder to expand, the gap between the plastic holder and the copper increases. The waterproof grooves and stamped layered sealing method cannot effectively prevent harmful elements from entering the LED lamp, ultimately causing the interior of the LED lamp to turn black.

[0032] In response to the above technical problems, the utility model provides an LED lamp bead patch bracket and an LED lamp bead, which connects the protruding foot and the soldering pad by using a connecting rod. After the plastic bracket is covered on the protruding foot and the connecting rod, the harmful elements on both sides of the protruding foot can be prevented from being infiltrated. By making the protruding copper sheet of the soldering pad located in the middle position of the soldering pad, after the plastic bracket is covered on the soldering pad, even when the LED lamp bead is lit and heated, the intrusion of harmful elements into the interior of the LED lamp bead can be reduced, thereby preventing the interior of the LED lamp bead from turning black due to the intrusion of harmful elements.

[0033] Please also see Figures 1 to 4 The utility model provides a preferred embodiment of an LED lamp bead patch bracket.

[0034] In some embodiments, as Figure 1 and Figure 2As shown, the present invention provides an LED lamp bead patch bracket, which includes: a plastic bracket 1, a soldering pad 2, a protruding foot 3, and a connecting rod 4. The soldering pad 2 is partially enclosed in the plastic bracket 1; the protruding foot 3 is spaced apart on one side of the soldering pad 2 and partially enclosed in the plastic bracket 1, and the protruding foot 3 protrudes from the plastic bracket 1; the connecting rod 4 is connected between the soldering pad 2 and the protruding foot 3.

[0035] Specifically, the LED lamp bead patch bracket includes two parts: a plastic bracket 1 and a copper sheet bracket. The soldering pad 2 and the protruding foot 3 are an integrated structure and are part of the copper sheet bracket. The protruding foot 3 is located on the side of the soldering pad 2. After digging a hole, the connecting rod 4 is retained to connect the protruding foot 3 and the soldering pad 2 to achieve the conductive function. The connecting rod 4 is stamped from the front so that the plastic can better wrap the protruding foot 3 and the connecting rod 4. In this way, the harmful elements on the side of the protruding foot 3 will be reduced along the bottom intrusion path, and the infiltration of harmful elements on both sides of the protruding foot 3 can be avoided. Even when the LED lamp bead is lit and heated, the harmful elements at the position of the protruding foot 3 can be reduced from intruding into the interior of the LED lamp bead, thereby avoiding the blackening of the interior of the LED lamp bead due to the intrusion of harmful elements into the LED lamp bead.

[0036] Furthermore, the pad 2 includes a positive pad 21 and a negative pad 22; the protrusion 3 includes a positive protrusion 31 and a negative protrusion 32; the connecting rod 4 includes a positive connecting rod 41 and a negative connecting rod 42; the positive connecting rod 41 is connected between the positive pad 21 and the positive protrusion 31; the negative connecting rod 42 is connected between the negative pad 22 and the negative protrusion 32.

[0037] Specifically, the LED lamp bead patch bracket has a positive pad 21, a negative pad 22, a positive convex foot 31 and a negative convex foot 32. The positive pad 21 and the positive convex foot 31 are connected by a positive connecting rod 41, and the negative pad 22 and the negative convex foot 32 are connected by a negative connecting rod 42.

[0038] Because the width of the connecting rod 4 affects the intrusion path of harmful elements, the width of the connecting rod 4 should not be too wide, nor too narrow. Too narrow will result in poor connection between the protruding foot 3 and the pad 2, resulting in poor conductivity and easy disconnection of the connecting rod 4. In some embodiments, the width of the positive electrode connecting rod 41 and the negative electrode connecting rod 42 is 0.1-0.2 mm, for example, 0.1 mm, 0.15 mm, or 0.2 mm.

[0039] In some embodiments, as Figure 2As shown, the connecting rod 4 is connected to the middle position of the protruding foot 3. Specifically, the positive connecting rod 41 is connected to the middle position of the positive protruding foot 31, and the negative connecting rod 42 is connected to the middle position of the negative protruding foot 32, which can make the force on both ends of the connecting rod 4 more uniform and not easy to break.

[0040] In some embodiments, as Figure 2 As shown, the side of the positive electrode pad 21 is a curved structure; the side of the negative electrode pad 22 is a curved structure.

[0041] Specifically, the sides of the positive electrode pad 21 and the negative electrode pad 22 are upwardly bent sheet structures, and the copper sheet of the sheet structure can be embedded in the plastic bracket 1, so that the pad 2 and the plastic bracket 1 can be better combined together. At the same time, the path for harmful elements to penetrate along the bottom analysis is also longer, thereby further improving the air tightness of the bracket.

[0042] In some embodiments, as Figure 2 and Figure 3 As shown, the positive electrode pad 21 has a first protruding copper sheet 211, which extends along the middle position of the positive electrode pad 21; the negative electrode pad 22 has a second protruding copper sheet 221, which extends along the middle position of the negative electrode pad 22.

[0043] Further, if Figure 1 and 4 As shown, Figure 4 A in the figure shows the structural diagram of the middle isolation zone in the prior art. Figure 4 Reference numeral b shows a schematic structural diagram of the intermediate isolation zone in the present invention. The plastic support 1 has an intermediate isolation zone 11 , and the intermediate isolation zone 11 is located between the positive electrode pad 21 and the negative electrode pad 22 .

[0044] Specifically, the first protruding copper sheet 211 and the second protruding copper sheet 221 are pressed by up and down stamping, so that the protruding copper sheet is located in the center of the copper sheet bracket. When the plastic bracket 1 is covered with the solder pad 2, the middle isolation belt 11 is formed in an I-shape, which can lengthen the penetration path of harmful elements and make it more difficult for harmful elements to penetrate into the interior of the bracket.

[0045] In some embodiments, the present invention further provides an LED lamp bead, which includes the LED lamp bead patch bracket described above. The LED lamp bead patch bracket is specifically as described in an embodiment of an LED lamp bead patch bracket, and will not be repeated here.

[0046] In summary, the LED lamp bead patch bracket and LED lamp bead provided by the present invention have the following beneficial effects:

[0047] The protruding foot is located on the side of the pad. After digging a hole, a connecting rod is retained to connect the protruding foot and the pad. This reduces the intrusion path of harmful elements on the protruding foot along the bottom, thus preventing the infiltration of harmful elements on both sides of the protruding foot.

[0048] The sides of the positive electrode pad and the negative electrode pad are upwardly curved sheet structures. The copper sheet of the sheet structure can be embedded in the plastic bracket, so that the pad and the plastic bracket can be better combined. At the same time, the path for harmful elements to penetrate along the bottom is also longer, thereby further improving the airtightness of the bracket;

[0049] The protruding copper sheet of the copper sheet bracket is located in the center of the copper sheet bracket. When the plastic bracket is covered on the soldering pad, the middle isolation zone formed is I-shaped, which can lengthen the penetration path of harmful elements and make it more difficult for harmful elements to penetrate into the bracket.

[0050] It should be understood that the application of the present invention is not limited to the above examples. For ordinary technicians in this field, they can make improvements or changes based on the above description. All these improvements and changes should fall within the scope of protection of the claims attached to the present invention.
