Abstract
Description
Technical Field
[0001] This utility model relates to an LED lamp bead and an LED bracket connecting plate with unpeeled LED lamp beads. Background Technology
[0002] In the field of LED lead frames, LED brackets are mainly made of steel or copper sheets. The conductive leads of the LEDs are punched out on these sheets, then electroplated with silver, and finally injection molded to form the LED lead frame. Existing LED lead frames generally use a one-time injection molding process. This method typically produces LED lead frames that are a single color. To make the outer surface of the LED plastic bracket black or another color, it is necessary to separately paint the outer surface of the LED plastic bracket. It is difficult to apply ink or other forms of coloring to all areas of the product except for the conductive leads.
[0003] There is an existing LED bracket connecting plate with unpeeled LED beads. The unbroken connecting bridge is shallowly embedded in the end of the LED plastic bracket to facilitate the subsequent peeling of the LED beads from the LED bracket connecting plate. However, during the injection molding process, the unbroken connecting bridge cannot be thickly wrapped, otherwise it will be difficult to peel it off later. It is necessary to solve this problem. Utility Model Content
[0004] This utility model overcomes the shortcomings of the above-mentioned technology and provides an LED lamp bead and an LED bracket connecting plate with unpeeled LED lamp beads.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] Compared with the prior art, the beneficial effects of this utility model are:
[0007] 1. The LED bead structure in this case is simple and easy to implement. Compared with the existing technology where only the LED bead support hole is left on the LED bead body, the LED bead body in this case has both the LED bead support hole and the first connecting bridge break. On the one hand, it is convenient to form the required LED bead body on the LED bracket connecting plate body through two or more injection molding processes as needed when the first connecting bridge break is not broken. On the other hand, it is convenient to peel the LED bead body from the LED bracket connecting plate body more easily after the first connecting bridge break, as the connection between the LED bead support hole and the second connecting bridge makes the LED bead body easier to peel off. In addition, the first connecting bridge break is located between the left and right LED bead support holes, which is beneficial to the balance of the LED bead body structure.
[0008] 2. The LED bracket connecting plate structure in this case is simple and easy to implement. Compared with the existing technology where the LED bracket connecting plate body is only connected to the LED lamp bead body through the second connecting bridge, this case has both a second connecting bridge and a broken first connecting bridge. On the one hand, it is convenient to form the required LED lamp bead body on the LED bracket connecting plate body through two or more injection molding processes as needed when the first connecting bridge is not broken. On the other hand, it is convenient to peel the LED lamp bead body from the LED bracket connecting plate body more easily through the connection of the second connecting bridge to the LED lamp bead body after the first connecting bridge is cut. In addition, the arrangement of the first connecting bridge broken body between the left and right second connecting bridges is beneficial to the balance of the LED lamp bead body structure.

[0011] Figure 3 This is one of the structural schematic diagrams of the LED bracket connecting plate in this case.
[0012] Figure 4 This is the second structural schematic diagram of the LED bracket connecting plate in this case.
[0013] Figure 5 This is the third structural schematic diagram of the LED bracket connecting plate in this case. Detailed Implementation
[0014] The following examples provide a more detailed description of the features and other related characteristics of this utility model, to facilitate understanding by those skilled in the art:
[0015] like Figures 1 to 2As shown, an LED bead includes an LED bead body 10, on which one or more LED chips are disposed. The left and right sides of the LED bead body 10 are respectively provided with a plurality of conductive pins 11 for electrical connection with the corresponding LED chips. The conductive pins 11 on each side are arranged front to back. At both the front and rear ends of the LED bead body 10, a first connecting bridge 12 that is not electrically connected to the conductive pins 11 and not electrically connected to the LED chips is embedded. The front first connecting bridge 12 is embedded in the LED bead body 10 from front to back, and the rear first connecting bridge 12 is embedded in the LED bead body 10 from back to front. The front end of the LED bead body 10 has a bead support hole 13 on the left and right sides of the front first connecting bridge 12, and the rear end of the LED bead body 10 has a bead support hole 13 on the left and right sides of the rear first connecting bridge 12.
[0016] like Figures 3 to 5 As shown, in specific implementation, when the first connecting bridge break 12 is not broken, it is integrated with the LED bracket connecting plate body 20. The reason why the first connecting bridge break 12 is embedded in the LED lamp bead body 10 is that during the injection molding of the LED lamp bead body 10, two or more injection molding processes are implemented as needed. The final formed LED lamp bead body 10 deeply encapsulates the first connecting bridge break 12, making it easier to peel the LED lamp bead body 10 from the LED bracket connecting plate body 20 when the first connecting bridge break 12 needs to be cut off later. Figure 3 , Figure 4 As shown, the presence of the LED bead support hole 13 indicates that the second connecting bridge 22 was not deeply wrapped during the injection molding of the LED bead body 10. In practice, this can be achieved by reducing the number of injection molding cycles that wrap the second connecting bridge 22. Thus, when the LED bead body 10 is peeled off from the LED bracket connecting plate body 20, the second connecting bridge 22 can be separated from the LED bead body 10, leaving the LED bead support hole 13 on the LED bead body 10.
[0017] As described above, the LED bead structure of this invention is simple and easy to implement. Compared with the existing technology where only the LED bead support hole 13 is left on the LED bead body 10, the LED bead body 10 of this invention has both the LED bead support hole 13 and the first connecting bridge break 12. On the one hand, it is convenient to form the required LED bead body 10 on the LED bracket connecting plate body 20 through two or more injection molding processes as needed when the first connecting bridge break 12 is not broken. On the other hand, it is convenient to peel the LED bead body 10 from the LED bracket connecting plate body 20 more easily after the first connecting bridge break 12 is broken, as the connection between the LED bead support hole 13 and the second connecting bridge 22 makes the LED bead body 10 easier to peel off. In addition, the first connecting bridge break 12 is located between the left and right LED bead support holes 13, which is beneficial to the balance of the LED bead body 10 structure.
[0018] As described above, in specific implementation, the first connecting bridge 12 does not protrude outside the LED lamp bead body 10, or the length of the first connecting bridge 12 protruding outside the LED lamp bead body 10 is less than its length embedded in the LED lamp bead body 10. In this way, on the one hand, the external size of the LED lamp bead body 10 is not increased as much as possible, and on the other hand, the first connecting bridge 12 is not exposed too much when viewed from the top of the product.
[0019] like Figure 1 As shown, in a specific implementation, the LED bead body 10 includes an inner injection molding body 101 located on the inside and used to form an inner cavity for accommodating the LED chip, and an outer injection molding body 102 located on the outside of the inner injection molding body 101. The middle section of each conductive pin 11 is wrapped by the outer injection molding body 102. Compared with the technical solution of bending the conductive pin 11 after injection molding, the technical solution of bending and then injection molding in this case is more convenient to fill the cracks caused by stress at the junction of the pin and the plastic during bending, and to make the conductive pin 11 connected firmly and tightly.
[0020] As described above, in specific implementation, after the inner injection molded body 101 is completed, the middle section of the conductive pin 11 can be bent as needed, and then the outer injection molded body 102 is injection molded. This facilitates filling the cracks caused by stress at the junction of the pin and the plastic during bending, so as to make the conductive pin 11 stable and tight.
[0021] As described above, in specific implementation, the inner injection molded body 101 is made of white material to facilitate the formation of a white inner cavity for accommodating the LED chip, which is beneficial to enhance the reflective effect. The outer injection molded body 102 is made of black or gray material, which is beneficial to improve the black contrast of the product and has good practicality.
[0022] like Figures 1 to 5As shown, this case also discloses an LED bracket connecting plate with unpeeled LED beads, including an LED bracket connecting plate body 20. The LED bracket connecting plate body 20 has a plurality of holes 21. An LED bead body 10 is provided at each hole 21. One or more LED chips are provided on the LED bead body 10. A plurality of conductive pins 11 for electrical connection with the corresponding LED chips are provided on the left and right sides of the LED bead body 10, respectively. The conductive pins 11 on each side are distributed front to back. The front and rear ends of the LED bead body 10 are respectively embedded with a first connecting bridge break 12 that is not electrically connected to the conductive pins 11 and not electrically connected to the LED chips. The first connecting bridge break 12 at the front end is embedded in the LED bead body 10 from front to back, and the first connecting bridge break 12 at the rear end is embedded in the LED bead body 10 from back to front. The LED bracket connecting plate body 20 located at the holes 21 has a plurality of second connecting bridges 22 connected to the front end of the LED bead body 10 and a plurality of second connecting bridges 22 connected to the rear end of the LED bead body 10.
[0023] As described above, the LED bracket connecting plate structure of this invention is simple and easy to implement. Compared with the existing technology where the LED bracket connecting plate body 20 is only connected to the LED lamp bead body 10 through the second connecting bridge 22, this invention has both the second connecting bridge 22 and the first connecting bridge break 12. On the one hand, it is convenient to form the required LED lamp bead body 10 on the LED bracket connecting plate body 20 through two or more injection molding processes as needed when the first connecting bridge break 12 is not broken. On the other hand, it is convenient to make the LED lamp bead body 10 easier to peel off from the LED bracket connecting plate body 20 by connecting it to the LED lamp bead body 10 through the second connecting bridge 22 after the first connecting bridge break 12 is cut. In addition, the first connecting bridge break 12 is located between the left and right second connecting bridges 22, which is beneficial to the structural balance of the LED lamp bead body 10.
[0024] As described above, in specific implementation, the first connecting bridge 12 does not protrude outside the LED lamp bead body 10, or the length of the first connecting bridge 12 protruding outside the LED lamp bead body 10 is less than its length embedded in the LED lamp bead body 10. In this way, on the one hand, the external size of the LED lamp bead body 10 is not increased as much as possible, and on the other hand, the first connecting bridge 12 is not exposed too much when viewed from the top of the product.
[0025] like Figure 1 , Figure 3As shown, the LED bead body 10 includes an inner injection molded body 101 located on the inside and used to form an inner cavity for accommodating the LED chip, and an outer injection molded body 102 located on the outside of the inner injection molded body 101. The middle section of each conductive pin 11 is wrapped by the outer injection molded body 102. Compared with the technical solution of bending the middle section of the conductive pin 11 after injection molding, the technical solution of this invention is to bend and then inject mold, which is convenient to fill the cracks caused by stress at the junction of the pin and the plastic during bending, and to make the conductive pin 11 connected firmly and tightly.
[0026] As described above, in specific implementation, after the inner injection molded body 101 is completed, the middle section of the conductive pin 11 can be bent as needed, and then the outer injection molded body 102 is injection molded. This facilitates filling the cracks caused by stress at the junction of the pin and the plastic during bending, so as to make the conductive pin 11 connected firmly and tightly.
[0027] As described above, in specific implementation, the inner injection molded body 101 is made of white material to facilitate the formation of a white inner cavity for accommodating the LED chip, which is beneficial to enhance the reflective effect. The outer injection molded body 102 is made of black or gray material, which is beneficial to improve the black contrast of the product and has good practicality.
[0028] like Figure 4 As shown, in specific implementation, at least one second connecting bridge 22 is located on the left side of the first connecting bridge segment 12 at the front end, at least one second connecting bridge 22 is located on the right side of the first connecting bridge segment 12 at the front end, at least one second connecting bridge 22 is located on the left side of the first connecting bridge segment 12 at the rear end, and at least one second connecting bridge 22 is located on the right side of the first connecting bridge segment 12 at the rear end. Its multi-point distributed connection has good stability.
[0029] As described above, in a specific implementation, the first connecting bridge section 12 is cut from the LED bracket connecting plate body 20, usually after the entire injection molding is completed.
[0030] As stated above, this case protects an LED lamp bead and an LED bracket connecting plate with unpeeled LED lamp beads. All technical solutions with the same or similar structure as this case should be considered to fall within the protection scope of this case.
