[0058] The embodiments of the present application are described in detail below in conjunction with the accompanying drawings. It should be understood that the embodiments of the present application are mainly for illustrating possible implementation methods of the technical solution of the present application and should not be understood as limiting the technical solution of the present application. In this specification, the same or similar parts are indicated by the same or similar reference numerals.

[0059] Figure 1a This is a schematic structural diagram of a light strip assembly 100 - 1 provided in the first embodiment of the present application. Figure 1b for Figure 1a A top view of the light strip assembly 100 - 1 is shown. Figure 1c for Figure 1a A partial enlarged view P1 of the light strip assembly 100 - 1 is shown. Figure 1d for Figure 1a The F1 - F1 cross-sectional diagram of the light strip assembly 100 - 1 is shown, and the F1 - F1 cross-sectional diagram is perpendicular to the extension direction D of the light strip assembly 100 - 1 . Figure 1e for Figure 1a and Figure 1b The D1 - D1 cross-sectional diagram of the light strip assembly 100 - 1 is shown, and the D1 - D1 cross-sectional diagram is parallel to the extension direction D of the light strip assembly 100 - 1 .

[0060] like Figure 1a-Figure 1eAs shown, the first embodiment of the present application provides a light strip assembly 100-1, which includes a flexible circuit board 10, a plurality of light sources 20, an optical structure 30, and an electrical connection portion 40. The flexible circuit board 10 may be a flexible PCB, and the light source 20 may be a light emitting diode LED, but the present application does not limit this. The plurality of light sources 20 are electrically connected to the flexible circuit board 10, and the plurality of light sources 20 are arranged at intervals along the extension direction D of the flexible circuit board 10, and the extension direction D of the flexible circuit board 10 is also the extension direction of the light strip assembly 100-1. The optical structure 30 includes a first end 30a, a second end 30b, a light emitting portion 31, and side portions 32a, 32b, and 32c. The first end 30a and the second end 30b are arranged opposite to each other. The light emitting portion 31 and the side portions 32a and 32b extend from the first end 30a to the second end 30b along the extension direction D. The side portions 32a, 32b, and 32c are connected to the light emitting portion 31. The flexible circuit board 10 and the plurality of light sources 20 are located in the optical structure 30. The light emitting portion 31 is used to emit light emitted by the plurality of light sources 20. An opening 30h is formed on the side portion 32a. The electrical connection portion 40 extends from the inside of the optical structure 30 to the outside of the optical structure 30 through the opening 30h.

[0061] In this embodiment, an opening 30h is formed on the side 32a of the optical structure 30, and the electrical connection part 40 uses the opening 30h as an extension channel to extend from the inside of the optical structure 30 to the outside, and the opening 30h avoids the light emitting part 31, so as not to affect the light emitting effect. When the light strip assembly 100-1 is used to form various shapes, the light emitting effect can be effectively avoided from being affected by the extension channel of the reserved electrical connection part 40, so that the light emitting of the light strip assembly 100-1 is more eye-catching, and when it is applied to a motor vehicle, the driving safety of the motor vehicle can be improved.

[0062] Figure 2a Shows Figure 1a The structure diagram of the flexible circuit board 10, the light source 20 and the electrical connection part 40 in the light strip assembly 100-1 is shown. Figure 2b Shows Figure 1a The optical structure 30 of the light strip assembly 100 - 1 shown is a schematic structural diagram in an initial state. Figure 2c Shows Figure 1a The optical structure 30 of the light strip assembly 100 - 1 shown is a schematic structural diagram after part of the optical structure is removed.

[0063] In the process of manufacturing the light strip assembly 100-1, as Figure 2a As shown, a flexible circuit board 10, a plurality of light sources 20 and an electrical connection portion 40 may be provided first. Figure 2bAs shown, the optical structure 30 is extruded, and the optical structure 30 covers the flexible circuit board 10, the plurality of light sources 20 and the electrical connection part 40. Figure 2c As shown, a portion of the optical structure 30 is removed to expose the electrical connection portion 40 and form an opening 30h. Finally, the electrical connection portion 40 is bent along the position where the opening 30h is located to form a Figure 1a The light strip assembly 100 - 1 is shown.

[0064] In this embodiment, the opening 30h is located at the first end 30a of the optical structure 30. In other embodiments, the opening 30h may also be located at the second end 30b of the optical structure 30, or at any position between the first end 30a and the second end 30b. In addition, the position of the opening 30h is not limited to the side 32a of the optical structure 30. In other embodiments, when the flexible circuit board 10 is located at the side 32b or 32c, correspondingly, the opening 30h may also be located on the side 32b or 32c of the optical structure 30. The present application does not limit the position of the opening 30h, as long as it can effectively avoid the light emitting portion 31 and does not affect the light emitting effect.

[0065] In this embodiment, the electrical connection portion 40 is composed of a connection circuit board, the connection circuit board 40 and the flexible circuit board 10 are an integral part, and the connection circuit board 40 is formed by bending from the end of the flexible circuit board 10. In other embodiments, the electrical connection portion 40 may also be in other forms, for example, the electrical connection portion 40 is composed of a wire or a connector, and the wire or the connector is electrically connected to the flexible circuit board 10. Specifically, the opening 30h exposes the via hole or the pad of the flexible circuit board 10, and the wire or the connector is soldered to the via hole or the pad.

[0066] In this embodiment, the electrical connection part 40 is used to transmit an external power signal and / or control signal to the multiple light sources 20 to control the actions of the multiple light sources 20. For example, the light source 20 may be a smart LED, and the electrical connection part 40 includes a power signal transmission line and a control signal transmission line. The electrical connection part 40 transmits the external power signal and control signal to each light source 20 to achieve various light functions, such as a running light effect, or a simultaneous lighting and simultaneous shutting effect.

[0067] In this embodiment, the light strip assembly 100-1 is flexible, so that various lighting shapes can be made using the flexible light strip assembly 100-1. Each of the light sources includes an LED, and the spacing between any two adjacent light sources 20 is the same, so as to achieve a uniform lighting effect. In other embodiments, the spacing between the light sources 20 may also be different.

[0068] like Figure 1dAs shown, the side portions 32a, 32b, 32c and the light exit portion 31 form a receiving space S, the flexible circuit board 10 and the plurality of light sources 20 are located in the receiving space S, and the flexible circuit board 10 is disposed on the side portion 32a. The side portion 32b is used to reflect the light L emitted by the plurality of light sources 20 to the light exit portion 31.

[0069] In some embodiments, a light diffusion structure may be formed on the light emitting portion 31 to diffuse the light L from the multiple light sources.

[0070] In some embodiments, the optical structure 30 may further include a transparent layer 33, which may be disposed on the side portion 32a and extend from the first end 30a of the optical structure 30 to the second end 30b, and the flexible circuit board 10 is disposed on the transparent layer 33. Specifically, the flexible circuit board 10 includes a front side and a back side that are disposed opposite to each other, the plurality of light sources 20 are disposed on the front side, and the back side is disposed on the transparent layer 33 and the side portion 32a. Thus, the back side of the flexible circuit board 10 can be seen through the transparent layer 33 to determine the location of the via or pad on the flexible circuit board 10 to which the electrical connection portion 40 needs to be connected.

[0071] In this embodiment, the back side of the flexible circuit board 10 is indirectly disposed on the transparent layer 33 and the side portion 32a through a heat sink 80. The number of heat sinks 80 is the same as the number of light sources 20. A plurality of light sources 20 are disposed on the front side of the flexible circuit board 10, and the heat sinks 80 are disposed on the back side of the flexible circuit board 10 in a one-to-one correspondence therewith, so as to better dissipate heat for each light source 20. In other embodiments, the back side of the flexible circuit board 10 may also be directly disposed on the transparent layer 33 and the side portion 32a without an additional heat sink.

[0072] It is worth noting that when the flexible circuit board 10 is disposed on the other side 32 b or 32 c , the transparent layer 33 is also disposed on the side 32 b or 32 c accordingly, so that the relevant features on the back side of the flexible circuit board 10 can be observed.

[0073] Figure 3a This is a schematic structural diagram of a light strip assembly 100 - 2 provided in the second embodiment of the present application. Figure 3b for Figure 3a The structure diagram of the light strip body 2 in the light strip assembly 100-2 is shown. Figure 3c for Figure 3a A schematic structural diagram of the fixing bracket 50 in the light strip assembly 100-2 is shown. Figure 3d Shows the Figure 3b The light strip body 2 shown is installed to Figure 3c A schematic structural diagram of the fixing bracket 50 is shown.

[0074] like Figure 3a-3d As shown, the structure of the light strip assembly 100-2 of the second embodiment is similar to that of the light strip assembly 100-1 of the first embodiment, and the main difference is that in addition to the flexible circuit board 10, multiple light sources 20, optical structure 30 and electrical connection part 40 that are the same as those of the light strip assembly 100-1, the light strip assembly 100-2 also includes a fixing bracket 50 and a cover plate 60. The flexible circuit board 10, the multiple light sources 20, the optical structure 30 and the electrical connection part 40 form the light strip body 2. The light strip body 2 is mounted on the fixing bracket 50 through the optical structure 30, and the light emitting part 31 faces the outside of the fixing bracket 50. The cover plate 60 is mounted on the fixing bracket 50 and covers part of the electrical connection part 40.

[0075] In this embodiment, the first end 30a and the second end 30b of the optical structure 30 are tightly spliced ​​together to form a closed structure; the light emitting portion 31 is a closed structure, and the light emitting portion 31 is used to form a light emitting light pattern with a closed structure. The closed structure is a square ring with rounded corners. In other embodiments, the closed structure can also be a circular ring or an elliptical ring. The present application does not limit the specific shape of the closed structure. The two ends of the optical structure 30 are tightly spliced ​​together, so that the light emitting shape of the entire light strip assembly 100-2 is closed, and there is no visual gap, so that a more beautiful shape can be achieved.

[0076] Figure 4a This is a schematic structural diagram of a light strip assembly 100 - 3 provided in the third embodiment of the present application. Figure 4b for Figure 4a A partial enlarged view P3 of the light strip assembly 100 - 3 is shown. Figure 4c for Figure 4a and Figure 4b The F3-F3 cross-sectional view of the light strip assembly 100-3 is shown in FIG. The F3-F3 cross-sectional view is perpendicular to the extension direction D of the light strip assembly 100-3, and the F3-F3 cross-sectional view is located at the pad for welding the electrical connection portion 40 on the flexible circuit board 10, and the F3-F3 cross-sectional view is located between two adjacent light sources 20, that is, it does not pass through the light source 20. Figure 4c It can be seen that there are four wires used as the electrical connection part 40, two of which are used as power lines for transmitting power signals, and the other two are used as signal lines for transmitting control signals. Figure 4d for Figure 4a The D3-D3 cross-sectional diagram of the light strip assembly 100 - 3 is shown, and the D3-D3 cross-sectional diagram is parallel to the extension direction D of the light strip assembly 100 - 3 .

[0077] like Figures 4a-4dAs shown, the structure of the light strip assembly 100-3 is basically the same as that of the light strip assembly 100-1, and the main difference is that the position of the opening 30h is different, and the structure of the electrical connection part 40 is different. The following is a detailed description of only the distinguishing features. As long as they do not conflict with each other, other features not described in the light strip assembly 100-3 can be exactly the same as those in the light strip assembly 100-1. In the light strip assembly 100-3, the opening 30h is located between the first end 30a and the second end 30b, and is close to the first end 30a. In other embodiments, the opening 30h can also be closer to the second end 30b, or located in the middle of the optical structure 30.

[0078] When the opening 30h is not located at the first end 30a and the second end 30b, but is located at a position between the first end 30a and the second end 30b, the method of bending the flexible circuit board 10 to form the electrical connection portion 40 is relatively complicated, so an additional wire or connector can be used as the electrical connection portion 40, and the wire or the connector is electrically connected to the flexible circuit board 10. Specifically, the opening 30h exposes the via hole or the pad of the flexible circuit board 10, and the wire or the connector is soldered to the via hole or the pad.

[0079] Figure 5a Shows Figure 4a A schematic structural diagram of the flexible circuit board 10 and the light source 20 in the light strip assembly 100 - 3 is shown. Figure 5b Shows Figure 5a The schematic structural diagram of the back side 10b of the flexible circuit board 10 is shown. Figure 5c Shows Figure 4a The optical structure 30 of the light strip assembly 100 - 3 shown is a schematic structural diagram in an initial state. Figure 5d Shows Figure 4a The optical structure 30 of the light strip assembly 100 - 3 shown is a schematic structural diagram after part of the optical structure is removed.

[0080] In the process of manufacturing the light strip assembly 100-3, as Figure 5a-5b As shown, a flexible circuit board 10 and a plurality of light sources 20 may be provided first, wherein the light sources 20 are arranged on the front side 10a of the flexible circuit board 10, and a solder pad 10p is arranged on the back side 10b of the flexible circuit board 10 for connecting to an external electrical connection portion 40. Figure 5c As shown, the optical structure 30 is extruded, and the optical structure 30 covers the flexible circuit board 10 and the plurality of light sources 20. Figure 5d As shown, a portion of the optical structure 30 is removed to form an opening 30h. Finally, the external electrical connection portion 40 passes through the opening 30h and is welded to the pad of the flexible circuit board 10 to form a Figure 4a The light strip assembly 100-3 is shown.

[0081] Figure 6a This is a schematic structural diagram of a light strip assembly 100 - 4 provided in the fourth embodiment of the present application. Figure 6b for Figure 6a The structure diagram of the light strip body 4 in the light strip assembly 100-4 is shown.

[0082] like Figure 6a-6b As shown, the structure of the light strip assembly 100-4 of the fourth embodiment is similar to that of the light strip assembly 100-3, and the main difference is that in addition to the flexible circuit board 10, multiple light sources 20, optical structure 30 and electrical connection part 40, the light strip assembly 100-4 also includes a fixing bracket 50 and a cover plate 60. The flexible circuit board 10, multiple light sources 20, optical structure 30 and electrical connection part 40 form a light strip body 4. The light strip body 4 is mounted on the fixing bracket 50 through the optical structure 30. The cover plate 60 is mounted on the fixing bracket 50 and covers part of the electrical connection part 40. The first end 30a and the second end 30b of the optical structure 30 are tightly spliced ​​together to form a closed structure, and the electrical connection part 40 is welded to the flexible circuit board 10 after passing through the opening 30h. The two ends of the optical structure 30 are tightly spliced, so that the light output optics of the entire light strip assembly are closed, and there is no gap visually, so that a more beautiful shape can be achieved.

[0083] Figure 7a It is a structural schematic diagram of a light strip assembly 100 - 5 shown in the fifth embodiment of the present application. Figure 7b Shows Figure 7a A front view of the light strip assembly 100 - 5 is shown. Figure 7c Shows Figure 7a A top view of the light strip assembly 100 - 5 is shown. Figure 7d Shows Figure 7a-7c The F51-F51 cross-sectional view of the light strip assembly shown in FIG. 1 is located at the pad on the flexible circuit board 10 for welding the electrical connection portion 40. The F51-F51 cross-sectional view is located between two adjacent light sources 20, that is, the cross-sectional view does not pass through the light source 20. Figure 7d It can be seen that there are four wires used as the electrical connection part 40, two of which are used as power lines for transmitting power signals, and the other two are used as signal lines for transmitting control signals. Figure 7e Shows Figure 7a-7c The F52 - F52 cross-sectional schematic diagram of the light strip assembly shown in the figure passes through one of the light sources 20 , and both the F51 - F51 cross-sectional view and the F52 - F52 cross-sectional view are perpendicular to the extension direction D of the light strip. Figure 7f Shows Figure 7a-7c The D5-D5 cross-sectional schematic diagram of the light strip assembly is shown, and the D5-D5 cross-sectional diagram is parallel to the extension direction D.

[0084] like Figures 7a-7f As shown, the structure of the light strip assembly 100-5 is basically the same as that of the light strip assembly 100-3, and the main difference is that the number of openings 30h and the electrical connection part 40 are different. The following is a detailed description of only the distinguished features. As long as they do not conflict with each other, other features not described in the light strip assembly 100-5 can be exactly the same as those in the light strip assembly 100-3. In the light strip assembly 100-5, the number of openings 30h is 2, and accordingly, the number of electrical connection parts 40 is also 2, and the flexible circuit board 10 includes two sub-circuits 11 and 12. The electrical connection parts 40 pass through the openings 30h one by one and are electrically connected to the corresponding sub-circuits 11 and 12. At this time, the two electrical connection parts 40 can respectively receive power signals and / or control signals to control the actions of the light sources 20 on the corresponding sub-circuits 11 and 12. The advantage of using two electrical connection parts is that two external drive circuits with lower power can be used instead of one drive circuit with higher power. Especially when the length of the light strip assembly 100 - 5 is very long, the number of light sources 20 is large, and the total power required to be provided by the driving circuit is large, the use of two electrical connecting parts 40 can significantly reduce the requirements for the external driving circuit.
