[0037] The technical solution of the present disclosure is further specifically described below through examples and in conjunction with the accompanying drawings. In the specification, the same or similar figure numbers indicate the same or similar parts. The following description of the embodiments of the present disclosure with reference to the accompanying drawings is intended to explain the overall inventive concept of the present disclosure and should not be construed as a limitation of the present disclosure.

[0038] In addition, in the detailed description below, for ease of explanation, many specific details are set forth to provide a comprehensive understanding of the disclosed embodiments. However, it is apparent that one or more embodiments may be implemented without these specific details. In other cases, well-known structures and devices are embodied in an illustrated manner to simplify the accompanying drawings.

[0039] like Figures 1 to 4 and Figure 7 As shown, a light strip assembly 100 according to an exemplary embodiment of the present disclosure includes a light strip body 70 and a lens element 20 disposed on the light strip body 70. The light strip body 70 includes a strip-shaped circuit board 40 and a plurality of light sources 30. The plurality of light sources 30 are connected (e.g., welded) to the circuit board 40 and are spaced apart along an extension direction X of the circuit board 40. The lens element 20 includes a light incident surface 21 and light emitting surfaces 22 and 23. The light incident surface 21 is used to receive light from the light source 30. The light emitting surfaces 22 and 23 are used to emit light entering the lens element 20 through the light incident surface 21, such as light rays c and d. In addition, the light emitting surfaces 22 and 23 are also used to reflect a portion of the light entering the lens element 20 through the light incident surface 21, such as light rays a1 and b1, toward opposite sides of the light source 30 along the extension direction X of the light strip assembly 100. For example, in Figure 3 At the viewing angle, the light emitting surfaces 22 and 23 reflect the light a1 and b1 toward the opposite left and right sides of the light source 30, and the extension direction X is Figure 3 The left and right direction of the viewing angle.

[0040] In the light strip assembly 100 according to the exemplary embodiment of the present disclosure, a part c and d of the light emitted by the light source 30 is incident from the light incident surface 21 of the lens element 20 and is emitted from the light emitting surfaces 22 and 23 of the lens element 20, while another part a1 and b1 of the light emitted by the light source 30 is incident from the light incident surface 21 of the lens element 20 and reaches the light emitting surfaces 22 and 23, and then is reflected by the light emitting surfaces 22 and 23 to be emitted toward the opposite sides of the light source 30 along the extension direction X of the light strip assembly 100. In this way, the light emitted by the light source 30 can be scattered in the extension direction X of the light strip assembly 100 to illuminate the area between adjacent light sources 30, thereby effectively improving the light emission uniformity of the light strip assembly 100 and avoiding the existence of dark areas between adjacent light sources 30. In addition, the spacing between adjacent light sources 30 can be enlarged, and in the light strip assembly 100 of the same length, a smaller number of light sources 30 can be set to achieve the same uniform light emission effect, so as to save costs.

[0041] Specifically, in this embodiment, the light emitting surfaces 22 and 23 include a first light emitting surface 22 and a second light emitting surface 23. The first light emitting surface 22 is used to direct a portion a1 of the light entering the lens element 20 through the light incident surface 21 toward one side of the light source 30 along the extension direction X ( Figure 3 The second light emitting surface 23 is used to direct a portion b1 of the light entering the lens element 20 through the light incident surface 21 toward the other side (the left side) of the light source 30 along the extension direction X. Figure 3 on the right side of the image) reflection.

[0042] It should be noted that although Figure 3In the exemplary embodiment shown, a portion of the light entering the lens element 20 through the light incident surface 21, such as the light a1 and the light b1, is reflected toward the opposite sides of the light source 30 along the extension direction X of the light strip assembly 100 through the light emitting surfaces 22 and 23. However, in some other embodiments of the present disclosure, only a portion of the light entering the lens element 20 through the light incident surface 21 may be reflected toward one side of the light source 30 along the extension direction of the light strip assembly 100. For example, in some embodiments, the lens element 20 includes only the first light emitting surface 22 and does not include the second light emitting surface 23. The first light emitting surface 22 only reflects a portion of the light entering the lens element 20 through the light incident surface 21 toward one side of the light source 30 along the extension direction of the light strip assembly 100 ( Figure 3 or, the lens element 20 includes only the second light emitting surface 23, but does not include the first light emitting surface 22, and the second light emitting surface 23 only allows a portion of the light entering the lens element 20 through the light incident surface 21 to be directed toward one side ( Figure 3 The right side of the reflection, that is, only retain Figure 3 The left or right half of lens element 20 is shown.

[0043] In this embodiment, if Figure 3 As shown, the lens element 20 also includes a third light emitting surface 25 and a fourth light emitting surface 26, the first light emitting surface 22 is connected between the light incident surface 21 and the third light emitting surface 25, the third light emitting surface 25 is used to emit the light a2 reflected from the first light emitting surface 21, the second light emitting surface 23 is connected between the light incident surface 21 and the fourth light emitting surface 26, and the fourth light emitting surface 26 is used to emit the light b2 reflected from the second light emitting surface 23.

[0044] In this embodiment, if Figure 3 As shown, along the direction from the third light emitting surface 25 to the light emitting axis o of the light source 30 ( Figure 3 The height of the first light emitting surface 22 is gradually reduced to direct a portion a1 of the light entering the lens element 20 through the light incident surface 21 toward one side of the light source 30 along the extension direction X ( Figure 3 The light is reflected from the left side of the image and emitted from the third light emitting surface 25. Similarly, along the direction from the fourth light emitting surface 26 to the light emitting optical axis o of the light source 30 ( Figure 3 The height of the second light emitting surface 23 is gradually reduced to direct a portion b1 of the light entering the lens element 20 through the light incident surface 21 toward the other side of the light source 30 along the extension direction X ( Figure 3 The light is reflected by the fourth light emitting surface 26.

[0045] In this embodiment, if Figure 1 , Figure 2 , Figure 3 and Figure 7 As shown, the cross-section of the first light emitting surface 22 along the direction perpendicular to the extension direction X is arc-shaped, and the cross-section of the second light emitting surface 23 along the direction perpendicular to the extension direction X is also arc-shaped; compared with the cross-section passing through the light emitting axis p and perpendicular to the extension direction X, the first light emitting surface 22 and the second light emitting surface 23 are symmetrically arranged, and the third light emitting surface 25 and the fourth light emitting surface 26 are symmetrically arranged, so that the light emitted by the light source 30 is evenly scattered on opposite sides of the extension direction X of the light strip assembly 100.

[0046] In this embodiment, if Figure 3 As shown, the first light emitting surface 22 and the second light emitting surface 23 are also configured as output refraction interfaces to refract a portion c and d of the light entering the lens element 20 through the light incident surface 21 toward opposite sides of the light source 30 along the extension direction X, so that the light emitted by the light source 30 is more evenly dispersed in the extension direction X of the light strip assembly 100.

[0047] In this embodiment, if Figure 2 As shown, a receiving groove 24 is formed on one side of the lens element 20 facing the light source 30, and the light source 30 is located in the receiving groove 24. Moreover, the light emitting surface 31 of the light source 30 may be close to one side of the lens element 20, that is, the light source 30 is tightly covered by the lens element 20. In some other embodiments of the present disclosure, the light emitting surface 31 of the light source 30 may not be close to the lens element 20, but may maintain a certain distance from the lens element 20.

[0048] In this embodiment, if Figure 1 and Figure 2 As shown, the light strip assembly 100 further includes a light-proof housing 10, in which the light strip body 70 and the lens element 20 are both disposed. The housing 10 may be made of, for example, a white reflective material, such as a light-proof and highly reflective silicone material.

[0049] In this embodiment, if Figure 2 As shown, the housing 10 includes two side walls 13 arranged opposite to each other, a bottom wall 15 connecting the two side walls 13, and an opening 14 arranged opposite to the bottom wall 15, that is, the cross section of the housing 10 perpendicular to the extension direction X is a U-shaped structure. The light emitted by the lens element 20 is emitted through the light output surface 12 located at the opening 14. In other embodiments of the present disclosure, the housing 10 may also be in other shapes, such as a groove-shaped structure with a trapezoidal cross-sectional shape and an opening on one side, or other shapes, as long as it is ensured that there is space inside it for arranging the light strip body 70 and the transmission element 20, and there is an opening for light emission.

[0050] In this embodiment, if Figure 2As shown, the circuit board 40 is fixedly connected to the side wall 13 of the housing 10, and the light emitting optical axis o of the light source 30 is perpendicular to the side wall 13 of the housing 10. In some other embodiments of the present disclosure, compared with the bottom wall 15 of the housing 10, the light emitting surface 31 of the light source 30 can also be inclined toward the opening 14 of the housing 10, such as Figure 5 In some other embodiments of the present disclosure, the circuit board 40 may also be fixedly connected to the bottom wall 15 of the housing 10, such as Figure 6 As shown, the light emitting surface of the light source 30 faces the opening of the housing 10 and is away from the bottom wall 15 of the housing 10 .

[0051] like Figure 5 and Figure 6 In the embodiment shown, a plurality of hard heat sinks 60 are correspondingly arranged on the side of the circuit board 40 opposite to the plurality of light sources 30 to dissipate the heat generated by the light sources 30 and the circuit board 40. In addition, the heat sink 60 can also be used to enhance the stability of the welding point between the light source 30 and the circuit board 40 to prevent the soldering pins of the light source 30 from breaking when the light strip assembly 100 is bent. It is worth noting that the number of heat sinks 60 can be the same as the number of light sources 30, and the plurality of heat sinks 60 are arranged one by one on the side of the circuit board 40 opposite to the plurality of light sources to ensure that the soldering pins of each light source 30 are protected.

[0052] In this embodiment, if Figure 2 As shown, the bottom wall 15 of the housing 10 is formed with a reflective surface 11 for reflecting the light emitted by the lens element 20 to the light output surface 12 of the light strip assembly 100, thereby improving the light output efficiency of the light strip assembly 100 and saving the number of light sources 30.

[0053] In this embodiment, if Figure 1 , Figure 2 and Figure 4 As shown, the light strip assembly 100 further includes a diffusion component 50 located at the opening 14 of the housing 10, the diffusion component 50 and the housing 10 enclose a cavity 80, and the light strip body 70 and the lens element 20 are located in the cavity 80. The diffusion component 50 can be made of, for example, semi-transparent silicone. The benefit of providing the diffusion component 50 is that it can further even out the light entering the light output surface 12 of the light strip assembly 100, thereby making the brightness of the light output surface 12 of the light strip assembly 100 very uniform.

[0054] In this embodiment, if Figure 4 As shown, a light deflection surface 51 is formed on one side of the diffusion component 50 close to the bottom wall 15 of the shell 10, and at least a portion of the light deflected by the light deflection surface 51 is closer to the side of the shell 10 on which the light strip body 70 is installed than before being deflected, so as to further improve the light uniformity of the light strip assembly 100.

[0055] In this embodiment, if Figure 4 As shown, a polarizing hole 52 is formed inside the diffusion component 50 for diffusing light. Of course, the diffused light can also be used for light mixing. Specifically, the side of the deflection hole 52 close to the light deflection surface 51 and the side away from the light deflection surface 51 are both curved to respectively converge and diffuse the light propagating through the diffusion component 50, thereby further improving the light uniformity of the light strip assembly 100.

[0056] In this embodiment, if Figure 2 As shown, the outer wall of the diffusion component 50 is tapered from one end away from the bottom wall 15 of the shell 10 toward the end close to the bottom wall 15 of the shell 10 (ie, the diffusion component 50 is trumpet-shaped) to further improve the light uniformity of the light strip assembly 100.

[0057] In this embodiment, the light strip assembly 100 is flexible, that is, the circuit board 40 is a flexible circuit board, such as a flexible printed circuit board (FPCB), and the lens element 20 and the housing 10 are also made of flexible materials (such as flexible silicone), so that the light strip assembly 100 can be bent, cut and installed easily. The housing 10 and the diffusion component 50 can be formed by an extrusion process. The light source 30 can be a light emitting diode LED.

[0058] In this embodiment, if Figure 7 As shown, the number of lens elements 20 can be multiple, and the multiple lens elements 20 are arranged on the multiple light sources 30 in a one-to-one correspondence to scatter the light emitted by each light source 30 in the extension direction X of the light strip assembly 100, so as to irradiate the area between adjacent light sources 30, so as to improve the light uniformity of the entire light strip assembly 100. Preferably, the multiple lens elements 20 are an integral part. Compared with each lens element 20 being processed and formed separately, arranging the multiple lens elements 20 as an integral part can improve the stability and integrity of the lens element 20, and the overall processing process is simpler. In some exemplary embodiments of the present disclosure, each lens element 20 can also be a separate component.

[0059] In this embodiment, if Figure 7 As shown, multiple lens elements 20 can be integrally formed on the circuit board 40 using transparent liquid silicone through a high-temperature injection molding process, which can simplify the processing engineering, reduce the processing difficulty, thereby reducing the processing cost, and at the same time improve the overall stability of the product. A connector 90 is formed between adjacent lens elements 20, and the connector 90 is formed with a protrusion, wherein the electronic device (such as a capacitor) of the light strip assembly 100 can be arranged under the protrusion.

[0060] According to another aspect of the present disclosure, Figure 8 and Fig.10 As shown, a lighting module 1000 is also provided. The lighting module 1000 includes a mounting frame 200 and the above-mentioned light strip assembly 100 fixed on the mounting frame 200 .

[0061] According to some exemplary embodiments of the present disclosure, Fig. 9 and Fig.11 As shown, a mounting groove 201 is formed on the mounting frame 200, and the light strip assembly 100 is mounted in the mounting groove 201. Since the light strip assembly 100 is a flexible light strip, the light strip assembly 100 can be bent, folded, and rolled at will to be mounted in the mounting groove 201, so that the light emitted by the light strip assembly 100 is in a desired shape. Figure 8 In the embodiment shown, the mounting groove 201 is rectangular, and a light strip assembly 100 can be bent into a rectangular structure, so that the light emitted by the light strip assembly 100 is rectangular. Fig.10 In the embodiment shown, the mounting groove 201 is spiral-shaped, and two light strip assemblies 100 can be bent and assembled into a spiral structure, so that the light emitted by the light strip assembly 100 is spiral-shaped. In some other embodiments of the present disclosure, the mounting groove 201 can also be other shapes, such as any polygon, circle, etc., and the light strip assembly 100 is bent into a corresponding shape and installed therein, so that the light pattern finally presented by the light strip assembly is the shape of the mounting groove.
