[0055] The technical solution of the present invention is further specifically described below by examples and in conjunction with the accompanying drawings. In the specification, the same or similar reference numerals represent the same or similar components. The following description of the embodiments of the present invention with reference to the accompanying drawings is intended to explain the overall inventive concept of the present invention and should not be construed as a limitation of the present invention.

[0056] In addition, in the following detailed description, for the purpose of explanation, many specific details are set forth to provide a comprehensive understanding of the embodiments of the present disclosure. However, it is apparent that one or more embodiments can also be implemented without these specific details.

[0057] Figure 1a A schematic diagram of the overall structure of a light strip assembly 100 - 1 according to a first embodiment of the present invention is shown. Figure 1b Show Figure 1a A partial structural diagram of a light strip assembly 100 - 1 is shown, showing a substrate 10 and a light source 20 . Figure 1c Show Figure 1a A schematic cross-sectional view of the light strip assembly 100-1 along the A1-A1 direction. Figure 1d Show Figure 1c FIG. 1 is an enlarged schematic diagram of a part P1 of the first light-transmitting layer 31 .

[0058] like Figure 1a-1d As shown, the first embodiment of the present invention provides a light strip assembly 100-1, which includes a substrate 10, a plurality of light sources 20, and a light-transmitting layer assembly 30. The plurality of light sources 20 are arranged on the substrate 10 at intervals along an extension direction D1 of the substrate 10. An optical microstructure 30m is arranged on the light-transmitting layer assembly 30, and the optical microstructure 30m is used to diffuse the light emitted by the plurality of light sources 20.

[0059] In this embodiment, the light strip assembly 100-1 includes a light-transmitting layer assembly 30. Compared with the semi-transmitting diffusion material, the light-transmitting layer assembly 30 has a relatively high light-emitting efficiency, so that the overall light-emitting efficiency of the light strip assembly 100-1 is relatively high. At the same time, by arranging an optical microstructure 30m for diffusing the light emitted by the light source 20 on the light-transmitting layer assembly 30, the uniformity of the light emitted by the entire light strip assembly 100-1 is significantly improved. Thereby, the light strip assembly 100-1 can have a higher light-emitting efficiency and better uniformity. When the length of the light strip assembly 100-1 is constant, the desired light-emitting effect can be achieved by arranging a smaller number of light sources 20, which obviously saves costs.

[0060] As an example, the light strip assembly 100-1 may be flexible. Among them, the substrate 10 may be a flexible printed circuit board, and the light-transmitting layer assembly 30 may also be flexible, so that the entire light strip assembly 100-1 is flexible, and the light strip assembly 100-1 can be bent into various shapes to create different lighting shapes. Each light source 20 may include at least one light emitting diode (LED) for emitting light. However, the embodiments of the present invention are not limited thereto, and according to actual needs, the light source 20 may be any light source that can emit light.

[0061] As an example, the light-transmitting layer assembly 30 can be made of a completely light-transmitting material, such as a transparent silicone material, however, the embodiments of the present invention are not limited thereto. The light-transmitting layer assembly 30 can be arranged on the transmission path of the light emitted by the multiple light sources 20, and the light-transmitting layer assembly 30 is extended along the extension direction D1, so that the light strip assembly 100-1 can emit a strip-shaped light pattern along the extension direction D1. The light emitted by all the light sources 20 can pass through the light-transmitting layer assembly 30, and after being diffused by the optical microstructure 30m, it is emitted to the outside of the light strip assembly 100-1, so that the light uniformity of the entire light strip assembly 100-1 can be better.

[0062] In this embodiment, the optical microstructure 30m may be in a tooth-shaped array or a pillow-shaped array. However, the embodiments of the present invention are not limited thereto, and may include optical microstructures arranged in other suitable shapes according to actual needs. The optical microstructure 30m can be used to scatter the light passing through it, thereby expanding the illumination range of the light. The size of the optical microstructure 30m is generally less than 50um, or even less than 10um. The smaller the size of the optical microstructure, the better the light can be scattered, thereby improving the diffusion effect. The optical microstructure 30m may cover a certain surface of the entire light strip assembly 30. Due to the small size of the optical microstructure 30m, the human eye generally cannot observe the structural details of the optical microstructure 30m, and can only see that the optical microstructure 30m is frosted.

[0063] As an example, the optical microstructure 30m can be formed on the light-transmitting layer component 30 by an embossing process. Specifically, the light-transmitting layer component 30 can be embossed with a film with the optical microstructure 30m, so that the optical microstructure 30m is formed on the light-transmitting layer component. In this embodiment, the optical microstructure 30m can be preferably formed on the light-transmitting layer component 30 by an embossing process.

[0064] In this embodiment, the light-transmitting layer assembly 30 includes only the first light-transmitting layer 31, and the first light-transmitting layer 31 includes a light-entering surface 31a and a light-emitting surface 31b that are arranged opposite to each other. The light-entering surface 31a of the first light-transmitting layer 31 is used to receive the light emitted by the plurality of light sources 20, and the light-emitting surface 31b of the first light-transmitting layer 31 is used to emit the light received from the light-entering surface 31a of the first light-transmitting layer 31.

[0065] As an example, the optical microstructure 30m can be disposed on the light emitting surface 31b of the first light-transmitting layer 31, and is used to disperse the light emitted by the multiple light sources 20 when the light is emitted, so as to improve the uniformity of the light emission. The first light-transmitting layer 31 is disposed on the multiple light sources 20 and the substrate 10, and the first light-transmitting layer 31 tightly covers the multiple light sources 20, that is, the first light-transmitting layer 31 completely contacts the multiple light sources 20, so that the multiple light sources 20 are located between the substrate 10 and the first light-transmitting layer 31.

[0066] At this time, the optical microstructure 30m of the light strip assembly 100-1 is exposed. An external component may be provided on the outside of the light strip assembly 100-1, and the external component is used to protect the optical microstructure 30m. For example, the light strip assembly 100-1 can be installed inside an exterior lamp, and the outer lens of the exterior lamp is used to protect the optical microstructure 30m to prevent the optical microstructure from dust accumulation, contamination or scratches. The exterior lamp may be, for example, a headlamp, a taillight, etc. In other embodiments, the light strip assembly 100-1 may also be used as an interior lamp. The working environment of the interior lamp is relatively clean, so there is no need to provide additional external components to protect the optical microstructure 30m.

[0067] In this embodiment, the light strip assembly 100-1 further includes a reflective layer 40, which covers the substrate 10 and the light-transmitting layer assembly 30. The reflective layer 40 is used to direct the light emitted by the light source 20 toward the light-emitting surface of the light-transmitting layer assembly 30, so as to further improve the overall light-emitting efficiency of the light strip assembly 100-1.

[0068] Specifically, a reflective layer 40 is formed outside the substrate 10 and the light-transmitting layer assembly 30, and the reflective layer 40 can be formed to surround at least a portion of the substrate 10 and the light-transmitting layer 31 from the outside. That is, the reflective layer 40 can be formed on the side of the substrate 10 opposite to the light-transmitting layer assembly 30, and cover at least a portion of the substrate 10. The reflective layer 40 can extend upward at both sides of the substrate 10 in the light-emitting direction transverse to the first direction D1, so as to cover at least a portion of both sides of the light-transmitting layer assembly 30 in the light-emitting direction, so as to surround the light-transmitting layer assembly from the side of the light-transmitting layer assembly 30. The substrate 10, the light source 20 and the light-transmitting layer assembly 30 can fill the entire space surrounded by the reflective layer 40. In this way, the reflective layer 40 can realize the supporting function of the substrate 10 and the light-transmitting layer assembly 30. And in the cross section perpendicular to the extension direction D1, the reflective layer 40 is roughly U-shaped. The reflective layer 40 can be in full contact with the printed circuit board 10 and the light-transmitting layer assembly 30. The reflective layer 40 may be formed of a completely light-proof and highly reflective material, such as a completely light-proof silicone material, and the reflective layer 40 may also be flexible. However, the embodiments of the present invention are not limited thereto.

[0069] In this embodiment, the light emitting surface 21 of the light source 20 is parallel to the light emitting surface of the light-transmitting layer component 30, and the light emitting surface 21 of the light source 20 faces the light emitting surface of the light-transmitting layer component 30. At this time, after the light emitted by the light source 20 is emitted from its light emitting surface 21, the main part can directly pass through the light-transmitting layer component 30 and be emitted from the light emitting surface of the light-transmitting layer component 30, and the other part will be reflected by the reflective layer 40 and then emitted through the light emitting surface of the light-transmitting layer component 30. In this embodiment, the light emitting surface of the light-transmitting layer component 30 is the light emitting surface 31b of the first light-transmitting layer 31.

[0070] Figure 2A schematic cross-sectional view of a light strip assembly 100 - 2 according to a second embodiment of the present invention is shown. Figure 3 FIG. 4 is a cross-sectional schematic diagram of a light strip assembly 100-3 according to a third embodiment of the present invention. Figure 2 , 3 As shown, the structures of the light strip assemblies 100-2 and 100-3 are substantially the same as those of the light strip assembly 100-1, and the main difference is that the angles between the light emitting surface 21 of the light source 20 and the light emitting surface of the light-transmitting layer assembly 30 are different. Figure 2 , the angle between the light emitting surface 21 of the light source 20 and the light emitting surface of the light-transmitting layer assembly 30 is an acute angle, and the light emitting surface 21 of the light source 20 faces the light emitting surfaces of the reflective layer 40 and the light-transmitting layer assembly 30. Figure 3 , the light emitting surface 21 of the light source 20 is perpendicular to the light emitting surface of the light-transmitting layer assembly 30, and the light emitting surface 21 of the light source 20 faces the reflective layer 40. At this time, most of the light emitted by the light source 20 is reflected by the reflective layer 40 and then emitted through the light emitting surface of the light-transmitting layer assembly 30. By setting the angle relationship between the light emitting surface 21 of the light source 20 and the light emitting surface of the light-transmitting layer assembly 30, the corresponding characteristics of the emitted light can be adjusted to meet the application of different scenes.

[0071] It is worth mentioning that Figure 2 and Figure 3 The light-transmitting layer assembly 30 also only includes the first light-transmitting layer 31, and the light-emitting surface of the light-transmitting layer assembly 30 is the light-emitting surface 31b of the first light-transmitting layer 31. Except for the different angles between the light-emitting surface 21 of the light source 20 and the light-emitting surface of the light-transmitting layer assembly 30, other features of the light strip assembly 100-2 and the light strip assembly 100-3 are the same or similar to those of the light strip assembly 100-1, and will not be repeated here.

[0072] Figure 4a A schematic diagram of the overall structure of a light strip assembly 100 - 4 according to a fourth embodiment of the present invention is shown. Figure 4b Show Figure 4a A schematic cross-sectional view of the light strip assembly 100-4 along the A4-A4 direction. Figure 4c Show Figure 4b FIG. 4 is an enlarged schematic diagram of a part P4 of the first light-transmitting layer 31. Figure 4a-4c As shown, the structure of the light strip assembly 100-4 is substantially the same as that of the light strip assembly 100-1, with the main difference being that, in the light strip assembly 100-4, the optical microstructure 30m is disposed on the light incident surface 31a of the first light transmissive layer 31, rather than being disposed on the light emitting surface 31b of the first light transmissive layer 31 similar to the light strip assembly 100-1.

[0073] In addition, unlike the first light-transmitting layer 31 in the light strip assembly 100-1, which completely and tightly covers the multiple light sources 20, in this embodiment, the first light-transmitting layer 31 is disposed on the side of the multiple light sources 20 away from the substrate 10, and the first light-transmitting layer 31 is spaced apart from the multiple light sources 20. Specifically, the first light-transmitting layer 31 has a thinner thickness, and the first light-transmitting layer 31 can be disposed at the opening of the U-shaped reflective layer 40, which can effectively save the material of the first light-transmitting layer 31. Other features in the light strip assembly 100-4 are the same or similar to those of the light strip assembly 100-1 and will not be repeated here.

[0074] In this embodiment, the optical microstructure 30m is disposed on the entire light incident surface 31a of the first light-transmitting layer 31, rather than being exposed, and the optical microstructure 30m can be protected by the entire first light-transmitting layer 31. This can prevent the optical microstructure 30m from failing due to dust accumulation, contamination or scratches. At this time, the light strip assembly 100-4 can be directly used as an exterior lamp or interior lamp, without the need to set up additional external parts to protect the optical microstructure 30m.

[0075] Figure 5 A schematic cross-sectional view of a light strip assembly 100 - 5 according to a fifth embodiment of the present invention is shown. Figure 6 FIG. 4 is a cross-sectional schematic diagram of a light strip assembly 100-6 according to a sixth embodiment of the present invention. Figure 5 , 6 As shown, the structures of the light strip assemblies 100-5 and 100-6 are substantially the same as those of the light strip assembly 100-4, and the main difference is that the angles between the light emitting surface 21 of the light source 20 and the light emitting surface of the light-transmitting layer assembly 30 are different. In the light strip assembly 100-5, the angle between the light emitting surface 21 of the light source 20 and the light emitting surface of the light-transmitting layer assembly 30 is acute, and the light emitting surface 21 of the light source 20 faces the light emitting surfaces of the reflective layer 40 and the light-transmitting layer assembly 30. In the light strip assembly 100-6, the light emitting surface 21 of the light source 20 is perpendicular to the light emitting surface of the light-transmitting layer assembly 30, and the light emitting surface 21 of the light source 20 faces the reflective layer 40. At this time, most of the light emitted by the light source 20 is reflected by the reflective layer 40 and then emitted through the light emitting surface of the light-transmitting layer assembly 30.

[0076] Figure 7a A schematic diagram of the overall structure of a light strip assembly according to a seventh embodiment 100-7 of the present invention is shown. Figure 7b Show Figure 7a A schematic cross-sectional view of the light strip assembly 100-7 along the A7-A7 direction. Figure 7c Show Figure 7b FIG. 1 is an enlarged schematic diagram of a part P7 of the first light-transmitting layer 31 and the second light-transmitting layer 32 in FIG. Figure 7d Show Figure 7b FIG. 1 is an enlarged schematic diagram of a part P7 of another variation of the first light-transmitting layer 31 and the second light-transmitting layer 32 in FIG.

[0077] like Figure 7a-7c As shown, the structure of the light strip assembly 100-7 is roughly the same as that of the light strip assembly 100-1, and the main difference is that in the light strip assembly 100-7, the light-transmitting layer assembly 30 includes not only a first light-transmitting layer 31, but also a second light-transmitting layer 32. The second light-transmitting layer 32 includes a light-entering surface 32a and a light-emitting surface 32b. The second light-transmitting layer 32 is arranged on the side of the first light-transmitting layer 31 away from the multiple light sources 20, and the second light-transmitting layer 32 is spaced apart from the first light-transmitting layer 31, and the light-entering surface 32a of the second light-transmitting layer 32 faces the light-emitting surface 31b of the first light-transmitting layer 31. The light-entering surface 32a of the second light-transmitting layer 32 is used to receive light emitted from the light-emitting surface 31b of the first light-transmitting layer 31, and the light-emitting surface 32b of the second light-transmitting layer 32 is used to emit light received from the light-entering surface 32a of the second light-transmitting layer 32.

[0078] In this embodiment, the optical microstructure 30m may be disposed on the light emitting surface 31b of the first light-transmitting layer 31. In a variant embodiment of this embodiment, as Figure 7d As shown, the optical microstructure 30m can also be arranged on the light incident surface 32a of the second light-transmitting layer 32. The second light-transmitting layer 32 can be made of the same material as the first light-transmitting layer 31, for example, both are made of transparent silicone material, and the second light-transmitting layer 32 can also be flexible. The optical microstructure 30m is arranged between the first light-transmitting layer 31 and the second light-transmitting layer 32, and the optical microstructure 30m can be protected by the second light-transmitting layer 32, thereby preventing the optical microstructure 30m from failing due to dust accumulation, contamination or scratches. At this time, the light strip assembly 100-7 can be used directly as an exterior lamp or an interior lamp, and there is no need to set up additional external parts to protect the optical microstructure 30m.

[0079] Figure 8 A schematic cross-sectional view of a light strip assembly 100 - 8 according to an eighth embodiment of the present invention is shown. Fig. 9 FIG. 4 is a cross-sectional schematic diagram of a light strip assembly 100-9 according to a ninth embodiment of the present invention. Figure 8 , 9 As shown, the structures of the light strip assemblies 100-8 and 100-9 are basically the same as those of the light strip assembly 100-7, and the main difference is that the angles between the light emitting surface 21 of the light source 20 and the light emitting surface 31 of the first light-transmitting layer 31 are different. In the light strip assembly 100-7, the light emitting surface 21 of the light source 20 is parallel to the light emitting surface 31 of the first light-transmitting layer 31, and the light emitting surface 21 of the light source 20 faces the light emitting surface 31 of the first light-transmitting layer 31. Figure 8 In the light strip assembly 100-8 shown, the angle between the light emitting surface 21 of the light source 20 and the light emitting surface 31 of the first light-transmitting layer 31 is acute, and the light emitting surface 21 of the light source 20 faces the reflective layer 40 and the light emitting surface 31 of the first light-transmitting layer 31. Fig. 9In the light strip assembly 100 - 9 shown, the light emitting surface 21 of the light source 20 is perpendicular to the light emitting surface 31 of the first light-transmitting layer 31 , and the light emitting surface 21 of the light source 20 faces the reflective layer 40 .

[0080] Fig.10a A schematic diagram of the overall structure of a light strip assembly 100 - 10 according to a tenth embodiment of the present invention is shown. Fig.10b Show Fig.10a A schematic cross-sectional view of the light strip assembly 100-10 along the A10-A10 direction. Fig.10c Show Fig.10b FIG. 3 is a partial enlarged schematic diagram of the first light-transmitting layer 31 in FIG. Figure 10a-10c As shown, the light strip assembly 100-10 is basically the same as the light strip assembly 100-1, and the main difference is that the light strip assembly 100-1 includes a reflective layer 40, while the light strip assembly 100-10 does not include a reflective layer, thereby saving costs. Because the light strip assembly 100-10 does not include a reflective layer, it is particularly suitable for scenes where the opponent can block the side of the light strip assembly 100-10 to prevent light leakage from the side of the light strip assembly 100-10. In addition, the first light-transmitting layer 31 in the light strip assembly 100-10 is square in cross-section along the direction perpendicular to the extension direction D1, while the first light-transmitting layer 31 in the light strip assembly 100-1 is lama-shaped in cross-section along the direction perpendicular to the extension direction D1.
