[0019] Detailed description of the embodiment Embodiments of this application are described below in detail with reference to the drawings. It should be understood that the embodiments of this application are possible embodiments intended primarily to illustrate the technical solutions of this application and should not be construed as limiting the technical solutions of this application. Here, identical or similar components are indicated by identical or similar reference numerals.

[0020] [Figure 1a] is a schematic diagram of the structure of a light strip assembly 100-1 provided in a first embodiment of this application. [Figure 1b] is a top view of the light strip assembly 100-1 shown in [Figure 1a]. [Figure 1c] is a partially enlarged view P1 of the light strip assembly 100-1 shown in [Figure 1a]. [Figure 1d] is a schematic diagram of a section F1-F1 of the light strip assembly 100-1 shown in [Figure 1a], where section F1-F1 is perpendicular to the extending direction D of the light strip assembly 100-1. [Figure 1e] is a schematic diagram of a section D1-D1 of the light strip assembly 100-1 shown in Figures 1a and 1b, where section D1-D1 is parallel to the extending direction D of the light strip assembly 100-1.

[0021] As shown in Figures 1a to 1e, a first embodiment of the present application provides a light strip assembly 100-1 comprising a flexible circuit board 10, a plurality of light sources 20, an optical structure 30, and an electrical connection part 40. The flexible circuit board 10 may be a flexible PCB, and the light sources 20 may be light-emitting diodes (LEDs), but the present application does not impose any limitations in this respect. The plurality of light sources 20 are electrically connected to the flexible circuit board 10, and the plurality of light sources 20 are spaced apart in the extending direction D of the flexible circuit board 10, which is also the extending direction D of the flexible circuit board 10. The optical structure 30 includes a first end 30a, a second end 30b, a light-emitting part 31, and side parts 32a, 32b, 32c. The first end 30a and the second end 30b are positioned opposite each other; the light-emitting section 31 and the side sections 32a and 32b all extend in the direction D from the first end 30a to the second end 30b; the side sections 32a, 32b and 32c are connected to the light-emitting section 31; the flexible circuit board 10 and the multiple light sources 20 are located within the optical structure 30; the light-emitting section 31 is used to output the light emitted by the multiple light sources 20; and an aperture 30h is formed in the side section 32a. The electrical connection section 40 extends from the inside of the optical structure 30 to the outside of the optical structure 30 through the aperture 30h.

[0022] In this embodiment, as a result of the aperture 30h being formed on the side 32a of the optical structure 30, the electrical connection portion 40 uses the aperture 30h as an extending channel to extend from the inside to the outside of the optical structure 30, and the aperture 30h avoids the light-emitting portion 31 so as not to affect the light output effect. When the light strip assembly 100-1 is used to form various shapes, any effect on the light output effect by ensuring an extending channel for the electrical connection portion 40 can be effectively avoided, thereby making the light emitted by the light strip assembly 100-1 more eye-catching; and, when used in a powered vehicle, it can make the operation of the powered vehicle safer.

[0023] Figure 2a shows a schematic diagram of the structure of the flexible circuit board 10, light source 20, and electrical connection part 40 in the light strip assembly 100-1 shown in Figure 1a. Figure 2b shows a schematic diagram of the structure of the optical structure 30 of the light strip assembly 100-1 shown in Figure 1a in its initial state. Figure 2c shows a schematic diagram of the structure of the optical structure 30 of the light strip assembly 100-1 shown in Figure 1a with a portion of the optical structure removed.

[0024] In the process of manufacturing the light strip assembly 100-1, the flexible circuit board 10, the multiple light sources 20, and the electrical connections 40 may be provided first, as shown in [Figure 2a]. Next, as shown in [Figure 2b], the optical structure 30 is extruded so that it surrounds the flexible circuit board 10, the multiple light sources 20, and the electrical connections 40. Then, as shown in [Figure 2c], a portion of the optical structure 30 is removed, exposing the electrical connections 40 and forming an opening 30h. Finally, the electrical connections 40 are bent along the position of the opening 30h to form the light strip assembly 100-1 shown in [Figure 1a].

[0025] In this embodiment, the aperture 30h is located at the first end 30a of the optical structure 30. In other embodiments, the aperture 30h may 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 aperture 30h is not limited to being on the side 32a of the optical structure 30. In other embodiments, when the flexible circuit board 10 is located on the side 32b or 32c, the aperture 30h may correspondingly be located on the side 32b or 32c of the optical structure 30. The present application does not limit the position of the aperture 30h as long as it can effectively avoid the light-emitting portion 31 and does not affect the light output effect.

[0026] In this embodiment, the electrical connection portion 40 is formed by a connecting circuit board; the connecting circuit board 40 and the flexible circuit board 10 are an integral component, and the connecting 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 take a different form; for example, the electrical connection portion 40 is formed by a conductive wire or connector, which is electrically connected to the flexible circuit board 10. Specifically, the opening 30h exposes a via or pad of the flexible circuit board 10, and the conductive wire or connector is soldered to the via or pad.

[0027] In this embodiment, the electrical connection unit 40 is used to transmit external power signals and / or control signals to the multiple light sources 20 in order to control the operation of the multiple light sources 20. For example, the light sources 20 may be smart LEDs, and the electrical connection unit 40 includes a power signal transmission line and a control signal transmission line, and the electrical connection unit 40 transmits external power signals and control signals to the light sources 20 to realize various optical functions such as a flowing water effect or simultaneous lighting and simultaneous extinguishing effects.

[0028] In this embodiment, the light strip assembly 100-1 is flexible; therefore, the flexible light strip assembly 100-1 can be used to form various light shapes. Each light source includes an LED, and to achieve a uniform illumination effect, the distance between any two adjacent light sources 20 is the same. In other embodiments, the distances between the light sources 20 may be different.

[0029] As shown in [Figure 1d], the side portions 32a, 32b, 32c and the light-emitting portion 31 form a housing space S, in which the flexible circuit board 10 and the multiple light sources 20 are arranged, and the flexible circuit board 10 is placed on the side portion 32a. The side portion 32b is used to reflect the light L emitted by the multiple light sources 20 to the light-emitting portion 31.

[0030] In some embodiments, a light diffusion structure may be formed on the light output section 31 to diffuse light L from multiple light sources.

[0031] In some embodiments, the optical structure 30 may further include a transparent layer 33; the transparent layer 33 may be located on the side portion 32a and extend from the first end 30a to the second end 30b of the optical structure 30, and the flexible circuit board 10 is located on the transparent layer 33. Specifically, the flexible circuit board 10 has a front and back surface located opposite each other; the light source 20 is located on the front surface, and the back surface is located on the transparent layer 33 and the side portion 32a. This makes it possible to view the back surface of the flexible circuit board 10 through the transparent layer 33 and determine the location of vias or pads on the flexible circuit board 10 to which the electrical connections 40 need to be connected.

[0032] In this embodiment, the back surface of the flexible circuit board 10 is indirectly positioned on the transparent layer 33 and the side portion 32a via cooling plates 80. The number of cooling plates 80 is the same as the number of light sources 20; the multiple light sources 20 are positioned on the front surface of the flexible circuit board 10, and the cooling plates 80 are positioned on the back surface of the flexible circuit board 10 in one-to-one correspondence with the light sources to more effectively dissipate heat from the light sources 20. In other embodiments, the back surface of the flexible circuit board 10 may be positioned directly on the transparent layer 33 and the side portion 32a without providing additional cooling plates.

[0033] It should be explained that when the flexible circuit board 10 is placed on another side portion 32b or 32c, the transparent layer 33 is also placed on the corresponding side portion 32b or 32c, and as a result, it can be used to observe relevant features on the back surface of the flexible circuit board 10.

[0034] Figure 3a is a schematic diagram of the structure of a light strip assembly 100-2 provided in a second embodiment of this application. Figure 3b is a schematic diagram of the structure of the light strip body 2 in the light strip assembly 100-2 shown in Figure 3a. Figure 3c is a schematic diagram of the structure of the fixing support 50 in the light strip assembly 100-2 shown in Figure 3a. Figure 3d is a schematic diagram of the structure of the light strip body 2 shown in Figure 3b, adapted to the fixing support 50 shown in Figure 3c.

[0035] As shown in Figures 3a to 3d, the light strip assembly 100-2 in the second embodiment is structurally similar to the light strip assembly 100-1 in the first embodiment; the main difference is that the light strip assembly 100-2 includes a fixed support 50 and a cover plate 60, in addition to the flexible circuit board 10, multiple light sources 20, optical structure 30, and electrical connection parts 40 which are identical to those in the light strip assembly 100-1. The flexible circuit board 10, multiple light sources 20, optical structure 30, and electrical connection parts 40 form the light strip body 2. The light strip body 2 is mounted on the fixed support 50 by the optical structure 30 with the light-emitting part 31 facing the outside of the fixed support 50. The cover plate 60 is mounted on the fixed support 50 and covers a portion of the electrical connection parts 40.

[0036] In this embodiment, the first end 30a and the second end 30b of the optical structure 30 are tightly joined to each other to form a closed structure; the light-emitting portion 31 has a closed structure and is used to form a light-emitting pattern having a closed structure. The closed structure is a square ring with rounded corners. In other embodiments, the closed structure may be a circular ring or an elliptical ring. This application does not limit the specific shape of the closed structure. Tightly joining the two ends of the optical structure 30 allows light to emerge from the entire light strip assembly 100-2 in a closed shape without any visible gaps, and as a result, a more attractive shape may be achieved.

[0037] [Figure 4a] is a schematic diagram of the structure of a light strip assembly 100-3 provided in a third embodiment of this application. [Figure 4b] is a partially enlarged view P3 of the light strip assembly 100-3 shown in [Figure 4a]. [Figure 4c] is a schematic diagram of a cross section F3-F3 of the light strip assembly 100-3 shown in Figures 4a and 4b, wherein the cross section F3-F3 is perpendicular to the extending direction D of the light strip assembly 100-3 and is located on a pad on the flexible circuit board 10 for soldering the electrical connections 40; the cross section F3-F3 is located between two adjacent light sources 20, i.e., does not pass through the light sources 20. Four conductive wires used as electrical connections 40 are visible in [Figure 4c], of which two conductive wires are used as power wires for transmitting power signals and the other two conductive wires are used as signal wires for transmitting control signals. Figure 4d is a schematic diagram of section D3-D3 of the light strip assembly 100-3 shown in Figure 4a, where section D3-D3 is parallel to the extension direction D of the light strip assembly 100-3.

[0038] As shown in Figures 4a-4d, the light strip assembly 100-3 has essentially the same structure as the light strip assembly 100-1; the main differences are the location of the aperture 30h and the structure of the electrical connection 40. Only the differing features are described in detail below; other features not described in the light strip assembly 100-3 may be exactly the same as those in the light strip assembly 100-1, provided they do not contradict each other. In the light strip assembly 100-3, the aperture 30h is located between the first end 30a and the second end 30b, and is close to the position of the first end 30a. In other embodiments, the aperture 30h may be closer to the second end 30b, or it may be located precisely in the center of the optical structure 30.

[0039] When the opening 30h is not located at the first end 30a or the second end 30b, but instead 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 40 is considerably more complex; therefore, an additional conductive wire or connector may be used as the electrical connection 40, and the conductive wire or connector is electrically connected to the flexible circuit board 10. Specifically, the opening 30h exposes a via or pad on the flexible circuit board 10, and the conductive wire or connector is soldered to the via or pad.

[0040] Figure 5a shows a schematic diagram of the structure of the flexible circuit board 10 and light source 20 in the light strip assembly 100-3 shown in Figure 4a. Figure 5b shows a schematic diagram of the structure of the back surface 10b of the flexible circuit board 10 shown in Figure 5a. Figure 5c shows a schematic diagram of the structure of the optical structure 30 of the light strip assembly 100-3 shown in Figure 4a in its initial state. Figure 5d shows a schematic diagram of the structure of the optical structure 30 of the light strip assembly 100-3 shown in Figure 4a with part of the optical structure removed.

[0041] In the process of manufacturing the light strip assembly 100-3, as shown in Figures 5a and 5b, a flexible circuit board 10 and a plurality of light sources 20 may be provided first, with the light sources 20 positioned on the front surface 10a of the flexible circuit board 10, and pads 10p for connecting external electrical connectors 40 provided on the back surface 10b of the flexible circuit board 10. Next, as shown in Figure 5c, an optical structure 30 is extruded so that the optical structure 30 surrounds the flexible circuit board 10 and the plurality of light sources 20. Then, as shown in Figure 5d, a portion of the optical structure 30 is removed to form an opening 30h. Finally, the external electrical connectors 40 are passed through the opening 30h and soldered to the pads of the flexible circuit board 10 to form the light strip assembly 100-3 shown in Figure 4a.

[0042] Figure 6a is a schematic diagram of the structure of a light strip assembly 100-4 provided in a fourth embodiment of this application. Figure 6b is a schematic diagram of the structure of the light strip body 4 in the light strip assembly 100-4 shown in Figure 6a.

[0043] As shown in Figures 6a-6b, the light strip assembly 100-4 in the fourth embodiment is structurally similar to the light strip assembly 100-3 in the third embodiment; the main difference is that the light strip assembly 100-4 includes a fixed support 50 and a cover plate 60, in addition to the flexible circuit board 10, multiple light sources 20, optical structure 30, and electrical connections 40 which are identical to those in the light strip assembly 100-3. The flexible circuit board 10, multiple light sources 20, optical structure 30, and electrical connections 40 form the light strip body 4. The light strip body 4 is mounted on the fixed support 50 by the optical structure 30. The cover plate 60 is mounted on the fixed support 50 and covers a portion of the electrical connections 40. The first end 30a and the second end 30b of the optical structure 30 are tightly joined to each other to form a closed structure, and the electrical connections 40 are soldered to the flexible circuit board 10 after passing through the opening 30h. By tightly joining the two ends of the optical structure 30 to each other, it is possible to allow light to emerge from the entire light strip assembly in an optically closed shape without any visible gaps, and as a result, a more attractive shape can be achieved.

[0044] Figure 7a is a schematic diagram of the structure of a light strip assembly 100-5 shown in a fifth embodiment of this application. Figure 7b is a front view of the light strip assembly 100-5 shown in Figure 7a. Figure 7c is a top view of the light strip assembly 100-5 shown in Figure 7a. Figure 7d is a schematic diagram of section F51-F51 of the light strip assembly shown in Figures 7a-7c, where section F51-F51 is located on a pad on the flexible circuit board 10 for soldering the electrical connection 40; section F51-F51 is located between two adjacent light sources 20, i.e., does not pass through the light sources 20. Four conductive wires used as electrical connection 40 are visible in Figure 7d, of which two conductive wires are used as power wires for transmitting power signals and the other two conductive wires are used as signal wires for transmitting control signals. [Figure 7e] shows a schematic diagram of the cross section F52-F52 of the light strip assembly shown in Figures 7a-7c, where the cross section passes through one of the light sources 20; both cross sections F51-F51 and F52-F52 are perpendicular to the extending direction D of the light strip. [Figure 7f] shows a schematic diagram of the cross section D5-D5 of the light strip assembly shown in Figures 7a-7c, where the cross section D5-D5 is parallel to the extending direction D.

[0045] As shown in Figures 7a-7f, the light strip assembly 100-5 has essentially the same structure as the light strip assembly 100-3; the main differences are the number of openings 30h and electrical connections 40. Only the differing features are described in detail below; other features not described in the light strip assembly 100-5 may be exactly the same as those in the light strip assembly 100-3, as long as they do not contradict each other. In the light strip assembly 100-5, there are two openings 30h, and correspondingly two electrical connections 40, and the flexible circuit board 10 includes two secondary circuit boards 11 and 12. The electrical connections 40 pass through the openings 30h in a one-to-one correspondence and are electrically connected to the corresponding secondary circuit boards 11 and 12. At this time, the two electrical connections 40 can each receive power signals and / or control signals to control the operation of the light sources 20 on the corresponding secondary circuit boards 11 and 12. The advantage of using two electrical connections is that two lower-power external drive circuits can be used instead of a single high-power drive circuit. In particular, when the light strip assembly 100-5 is very long, the number of light sources 20 is large, and the total power that the drive circuit needs to provide is high, using two electrical connections 40 can significantly reduce the requirements on the external drive circuit.

[0046] In other embodiments, the number of openings 30h is not limited to 2, but can be 1 or any other number greater than 1. For example, the number of openings 30h may be defined as N, the number of electrical connections 40 is also N, the flexible circuit board 10 includes N secondary circuit boards, N is an integer of 1 or more, and the electrical connections 40 pass through the openings 30h in a one-to-one correspondence with them and are electrically connected to the corresponding secondary circuit boards.

[0047] Figure 8a is a schematic diagram of the structure of a light strip assembly 100-6 provided in a sixth embodiment of this application. Figure 8b is a schematic diagram of the structure of the light strip body 6 in the light strip assembly 100-6 shown in Figure 8a.

[0048] As shown in Figures 8a-8b, the light strip assembly 100-6 is structurally similar to the light strip assembly 100-5; the main difference is that the light strip assembly 100-6 includes a fixed support 50 and a cover plate 60, in addition to the flexible circuit board 10, multiple light sources 20, optical structure 30, and electrical connections 40 which are identical to those in the light strip assembly 100-5. The flexible circuit board 10, multiple light sources 20, optical structure 30, and electrical connections 40 form the light strip body 6.
