[0054] In conjunction with the accompanying drawings, some embodiments of the present invention are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0055] With the rapid development of the electronics industry, electronic products have gradually become popular in people's daily lives. Data cables, which are used for data transmission or charging of electronic products, have become an indispensable part of our lives.

[0056] The existing data cable emits light through the USB connectors at both ends of the cable structure and the LED light strings on the charging plug, and then a notch is made on the surface of the optical fiber to guide the light outward through the notch, so that the cable is in a luminous state when observed with the naked eye. However, since two sets of control chips are required to control the simultaneous illumination of the upper and lower sides of the cable, the control logic of the LED lamp beads is complicated and the cost is high, and it is difficult to achieve synchronous illumination of the upper and lower sides.

[0057] To solve the above problems, please refer to Figures 1 to 13 ,like Figures 1 to 13As shown, the utility model provides an LED lamp bead 10, including an insulating seat 11, conductive pins (including a first conductive pin 12 and a second conductive pin 13), a first light-emitting chip group 14, a second light-emitting chip group 15, a first adhesive layer 16, a second adhesive layer 17 and a driving chip 18. The insulating seat 11 includes a first end face 111 and a second end face 112 arranged opposite to each other; the conductive pins are arranged on the first end face 111 and the second end face 112 of the insulating seat; the first light-emitting chip group 14 is located at the first end face 111 of the insulating seat 11, and the first light-emitting chip group 14 is electrically connected to the conductive pins; the second light-emitting chip group 15 is located at the second end face 112 of the insulating seat 11, and the second light-emitting chip group 15 is electrically connected to the conductive pins; the first adhesive layer 16 is encapsulated outside the first light-emitting chip group 14; the second adhesive layer 17 is encapsulated outside the second light-emitting chip group 15; the driving chip 18 is located at the first end face 111 or the second end face 112 of the insulating seat 11, and the driving chip 18 is electrically connected to the conductive pins, and is used to drive the first light-emitting chip group 14 and the second light-emitting chip group 15 to emit light.

[0058] The embodiment of the utility model simplifies the structure of the LED lamp bead 10, and the driving chip 18 of the first light-emitting chip group 14 is electrically connected to the first light-emitting chip group 141 and the second light-emitting chip group 151 at the same time, so that the driving chip 18 can respectively control the first light-emitting chip group 141 and the second light-emitting chip group 151 to emit light. While simplifying the control logic of the LED lamp bead 10, the cost of the LED lamp bead 10 can also be reduced.

[0059] In some embodiments, Figure 3 As shown, the first adhesive layer 16 and the insulating seat 11 form a first boss structure 161, and the two sides of the first boss structure 161 are used as follows Fig.14 As shown, an external first wire 20 and a second wire 30 are provided, and the first wire 20 and the second wire 30 are electrically connected to the conductive pin; the second adhesive layer 17 and the insulating seat 11 form a second boss structure 171. The provided LED lamp bead 10 also includes: a first shading member 19a and a second shading member 19b, and the first shading member 19a and the second shading member 19b are arranged on both sides of the second boss structure 171; wherein the first wire 20 and the second wire 30 have a shading effect on the side of the first light-emitting chip group 14, and the first shading member 19a and the second shading member 19b have a shading effect on the side of the second light-emitting chip group 15, so that the first light-emitting chip group 14 and the second light-emitting chip group 15 have the same luminous effect, and the luminous effect includes factors such as color, light intensity, and angle.

[0060] It should be noted that the first adhesive layer 16 and the second adhesive layer 17 can be any one of a transparent adhesive layer and a diffusion adhesive layer.

[0061] Specifically, Figures 1 to 4As shown, the provided LED lamp bead 10 uses an insulating base 11 as a base material, and a first light-emitting chip group 14 is arranged on a first end surface 111 of the insulating base 11, and a second light-emitting chip group 15 is arranged on a second end surface 112 of the insulating base 11 opposite to the first end surface 111. Since the outside of the first light-emitting chip group 14 of the provided LED lamp bead 10 is encapsulated by a first adhesive layer 16, a first boss structure 161 is formed on the outside of the first adhesive layer 16. When driving the LED lamp bead 10, it is necessary to electrically connect the first wire 20 and the second wire 30 to the first conductive pin 12 and the second conductive pin 13 on both sides of the first boss structure 161, respectively, so as to drive the first light-emitting chip group 14 and the second light-emitting chip group 15 to emit light. Figure 1 and Figure 2 As shown, when the first wire 20 and the second wire 30 are electrically connected to the LED lamp bead 10, the first wire 20 and the second wire 30 will shield the two sides of the first boss structure 161 of the LED lamp bead 10. At this time, if the LED lamp bead 10 is lit, the light emitted by the first light-emitting chip group 14 and the second light-emitting chip group 15 will be uneven up and down. At the same time, the light-emitting effect of the provided LED lamp bead 10 includes factors such as color, light intensity, and angle, resulting in the LED lamp bead 10 achieving unsatisfactory effects of flowing water and running horses.

[0062] The LED lamp bead 10 provided by the present invention is to achieve consistent luminous effects of the first light-emitting chip group 14 and the second light-emitting chip group 15, by providing a first shading member 19a and a second shading member 19b on both sides of the second boss structure 171 outside the second light-emitting chip group 15, so that the first shading member 19a and the second shading member 19b can also play a shading role on both sides of the second light-emitting chip group 15 of the LED lamp bead 10. When the first light-emitting chip group 14 and the second light-emitting chip group 15 are driven to emit light at the same time, the provided LED lamp bead 10 can make the two ends emit consistent light from the same angle, enriching the luminous effect of the LED lamp bead 10.

[0063] In some embodiments, the heights of the first wire 20 and the second wire 30 relative to both sides of the first boss structure 161 are the first heights. The heights of the first light shielding member 19a and the second light shielding member 19b relative to both sides of the second boss structure 171 are the second heights. The second height and the first height are less than a preset threshold.

[0064] The first wire 20 and the second wire 30 are selected according to the actual application product of the LED lamp bead 10, and the embodiment of the utility model does not limit the specification parameters of the first wire 20 and the second wire 30. At the same time, according to the height of the first wire 20 and the second wire 30 relative to the first boss structure 161, and the first wire 20 and the second wire 30 relative to the first boss structure 161, the first height of the light shielding surface is formed, so that the light emitted by the first light-emitting chip group 14 through the side of the first boss structure 161 is blocked. At the same time, by making the height of the first light shielding member 19a and the second light shielding member 19b relative to the second boss structure 171 The height of the light shielding surface is substantially the same as the first height, and by making the difference between the second height and the first height less than the preset threshold, the first light shielding member 19a and the second light shielding member 19b will form a light shielding surface with the second height on both sides of the second boss structure 171. The degree of light blocking on both sides of the second light-emitting chip group 15 is close to that of the first light-emitting chip group 14, so that the upper and lower light-emitting effects of the provided LED lamp bead 10 are highly consistent.

[0065] It should be noted that in order to improve the preparation speed and cost of the provided LED lamp beads, the provided method can complete the preparation of the provided LED lamp beads by making the first height and the second height approximately the same, and the difference between the first height and the second height is set according to the precision requirements of the actual product. If the difference between the first height and the second height is within a preset difference, such as ±8mm, it is considered that the first height and the second height are approximately the same. The embodiment of the utility model does not limit the preset difference between the first height and the second height.

[0066] For example, please refer to Figure 12 to Figure 13 The LED lamp bead 10 also includes: a substrate 10f, the substrate 10f includes a lamp bead placement area, and the first boss structure 161 of the LED lamp bead is placed in the lamp bead placement area. The third light shielding member 10g and the fourth light shielding member 10h, the third light shielding member 10g is set and the fourth light shielding member 10h is set on the other two sides of the second boss structure 171; wherein, the first wire 20, the second wire 30 and the substrate 10f will shield the surroundings of the first light-emitting chip group 14, and the first light shielding member 19a, the second light shielding member 19b, the third light shielding member 10g and the fourth light shielding member 10h will shield the surroundings of the second light-emitting chip group 15, so that the first light-emitting chip group 14 and the second light-emitting chip group 15 emit light evenly.

[0067] It should be noted that the substrate 10f can be a PCB board, and the first wire 20 and the second wire 30 are built into both sides of the PCB board. When a groove is opened in the PCB board for placing the LED lamp bead 10, since the thickness of the PCB board itself will block the other two sides of the first light-emitting chip group 14, it is necessary to set a third light-shielding member 10g and a fourth light-shielding member 10h to block the other two sides of the second light-emitting chip group 15, so that the first light-emitting chip group 14 and the second light-emitting chip group 15 have the same light-emitting effect, that is, the light intensity, color, and angle are the same.

[0068] It should be noted that, in some embodiments, the first light shielding member 19a, the second light shielding member 19b, the third light shielding member 10g and the fourth light shielding member 10h are integrally formed.

[0069] It should be noted that the materials of the insulating seat 11, the first light shading member 19a, the second light shading member 19b, the substrate 10f, the third light shading member 10g and the fourth light shading member 10h can be the same or different, such as any material such as ceramic, substrate, BT board, etc., among which the materials of the first light shading member 19a, the second light shading member 19b, the substrate 10f, the third light shading member 10g and the fourth light shading member 10h can also be any opaque colloid or light-blocking glass plate. The embodiment of the utility model does not limit the materials of the insulating seat 11, the first light shading member 19a, the second light shading member 19b, the substrate 10f, the third light shading member 10g and the fourth light shading member 10h.

[0070] It should be noted that the LED lamp beads provided in the embodiment of the utility model can also be provided with a corresponding driving chip 18 in the second light-emitting chip group 15, so as to control the first light-emitting chip group 141 and the second light-emitting chip group 151 separately.

[0071] For example, please refer to Figures 5 to 11The conductive pins include a first conductive pin 13 and a second conductive pin 14. The first conductive pin 12 is disposed on the first end surface 111 and the second end surface 112 of the insulating seat 11. The second conductive pin 13 is disposed on the first end surface 111 and the second end surface 112 of the insulating seat 11 relative to the first conductive pin 12. The driving chip 18, the light-emitting chip 141 of the first light-emitting chip group 141 and the light-emitting chip 151 of the second light-emitting chip group 151 are electrically connected to the first conductive pin 12, and the driving chip 18 and the second conductive pin 13 are electrically connected. The first conductive pin 12 includes a solid crystal portion 121 and a welding portion 122, and the second conductive pin 13 includes a solid crystal portion 131 and a welding portion 132. 2. The crystal-fixing portion 121 of the first conductive pin 12 is located at the first end surface 111 and the second end surface 112 of the insulating seat 11, and the crystal-fixing portion 131 of the second conductive pin 13 is located at the second end surface 112 of the insulating seat 11; the welding portion 122 of the first conductive pin 12 is located at the first end surface 111 and the second end surface 112 of the insulating seat 11, and the welding portion 132 of the second conductive pin 13 is located at the first end surface 111 and the second end surface 112 of the insulating seat 11, and the welding portion 122 and the welding portion 132 on the first end surface 111 and the second end surface 112 are respectively connected through vias to enhance the welding strength of the LED lamp bead 10, so that part of the welding material can be accommodated on the via structure. The crystal-fixing portion 121 of the first conductive pin 12 and the crystal-fixing portion 131 of the second conductive pin 13 are both located in the first adhesive layer 16 and the second adhesive layer 17, and the welding portion 122 of the first conductive pin 12 and the welding portion 132 of the second conductive pin 13 are located outside the first adhesive layer 16 and the second adhesive layer 17.

[0072] It should be noted that, in some embodiments, the light emitting chip 141 of the first light emitting chip group 141 is disposed on the crystal-fixing portion 121 of the first conductive pin 12 located on the first end surface 111.
