Obviously, the described embodiment is one embodiment of the utility model, not all embodiments of the utility model. Based on this embodiment of the utility model, all other embodiments of the utility model obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0038] See also Figures 1 to 12 , an embodiment of the utility model provides an atmosphere lamp light guide.

[0039] Example 1

[0040] like Figure 1-Figure 3The ambient light light guide of the present embodiment includes: a PCB board 1 and a light guide body 2, on which a plurality of groups of equidistantly arranged LED lamp beads 11 are arranged; the light guide body 2 includes a light emitting portion 21 and a light entering portion 22, and the PCB board 1 is snapped onto one side of the light entering portion 22. Specifically, an embedded groove 221 is provided on the light emitting portion 21, and a mounting boss 222 is provided on the embedded groove 221. The PCB board 1 is provided with a mounting through hole 12 matching the mounting boss 222. During assembly, the mounting through hole 12 of the PCB board 1 is aligned with the mounting boss 222, and then the PCB board 1 is directly inserted into the embedded groove 221. In this way, the PCB board 1 is snapped into the embedded groove 221 through the cooperation of the mounting boss 222 and the mounting through hole 12, so that the PCB board 1 is combined with the light guide body 2 after installation and will not be exposed, thereby optimizing the overall structure and reducing the overall thickness.

[0041] In this embodiment, a concave reflective structure 223 is provided on the other side of the light entrance portion 22. The reflective structure 223 is arranged opposite to the LED lamp bead 11, and the number of the reflective structures 223 corresponds to the LED lamp bead 11. The inner wall surface of the reflective structure 223 forms an inclined reflective surface 2231. The reflective surface 2231 is a flat surface 2231, which can effectively reflect the light of the LED lamp bead 11 to the light exit portion 21 for output. Optical microstructures 224 are evenly arranged on the reflective surface 2231 to adjust the incident light so that the light can be evenly emitted from the light exit portion 21. In order to make the incident angle of the light source more reasonable, the optical microstructure 224 can be a nanoscale microstructure, such as Figures 7 to 10 The shape of the optical microstructure 224 of the embodiment shown is a V-shaped texture, and of course, it can also be a combination of one or more of the pyramid texture, spherical texture, and conical texture shown in Figure 1. In this embodiment, the optical microstructure 224, the light input portion 22, the light guide portion 23, and the light output portion 21 are integrally formed. The integral forming can achieve high uniformity of the brightness of the entire light guide by adjusting the texture structure of the optical microstructure on the mold. Moreover, the required shape can be obtained without secondary hot pressing of the product, which can meet various customization needs, and the shape is stable and easy to install.

[0042] The reflective structure 223 further includes an inner concave edge 2232 connected to one end of the reflective surface 2231. The inner concave edge 2232 is recessed toward the PCB board 1, so that the reflective surface 2231 is inclined in the direction of the light of the LED lamp bead 11. Figure 3 As shown, the inner concave edge 2232 is set as an arc, so that the transition between the inner concave edge 2232 and the reflecting surface 2231 can be smoother. Of course, the inner concave edge 2232 can also be as Figure 4The straight setting shown, whether the inner concave edge 2232 is arc or straight, is to cooperate with the reflective surface 2231 to be better tilted on the light path emitted by the LED lamp bead 11. The depth of the inner concave edge 2232 determines the tilt angle of the reflective surface 2231.

[0043] In particular, a concave light-scattering structure 225 is provided on the light-entering portion 22, and the LED lamp bead 11 is adjacent to the concave light-scattering structure 225. Figure 3 and Figure 4 As shown, in this example, the concave light-scattering structure 225 is a straight light-scattering surface. Of course, the concave light-scattering structure 225 can also be as Figure 5 The arc-shaped light-scattering surface and the concave light-scattering structure 225 shown can be selected according to actual conditions. Both can realize the light-scattering function of the LED lamp bead 11, so that the light emitted by the LED lamp bead 11 is incident on the light input part 22 from the concave light-scattering structure 225, thereby improving the coverage range of the light source.

[0044] like Figure 3 As shown, a straight light guiding portion 23 is provided between the light input portion 22 and the light output portion 21. The light guiding portion 23 makes the light output portion 21 and the light input portion 22 separated from each other. The provision of the light guiding portion 23 can increase the sufficient distance of the light after reflection, reduce the interference of the LED lamp, and ensure the stability and uniformity of the light output.

[0045] In order to further reduce the thickness of the light guide body 2, one side of the light entrance portion 22 of the present embodiment is an inclined edge 226, and the inclined edge 226 gradually rises from the end of the light entrance portion 22 toward the light guide portion 23. In this way, while being able to meet the function of the reflective structure 223, the thickness of the light entrance portion 22 can be effectively reduced, thereby improving the applicability of the present application.

[0046] The light path of this embodiment is that the light source is emitted from the LED lamp bead 11, such as Figure 5 and Figure 6 The light enters the concave light diffusion structure 225 , diffuses and staggers the light source through the concave light diffusion structure 225 to form a larger area of ​​light, and then adjusts the light through the optical microstructure 224 of the reflective surface 2231 so that the light can be reflected uniformly, and finally emitted through the light output portion 21 .

[0047] Example 2

[0048] The difference between this embodiment and embodiment 1 is that Fig.11As shown, the reflecting surface 2231 in this embodiment is an arc-shaped surface. Setting the arc-shaped surface can effectively increase the range of reflection adjustment of the incident light, thereby increasing the reflection effect. Furthermore, since the reflecting surface 2231 is set as a arc-shaped surface, the depth of the concave edge 2232 needs to be set deeper than that of Example 1. Therefore, the concave edge 2232 of this embodiment is set vertically, and the rest is the same as Example 1, and the effect of Example 1 is also achieved.

[0049] Example 3

[0050] The difference between this embodiment and embodiment 1 is that Fig.12 As shown, the reflecting surface 2231 in this embodiment includes a first reflecting surface 22311 and a second reflecting surface 22312, and the first reflecting surface 22311 and the second reflecting surface 22312 are connected at an angle. The two reflecting portions connected at an angle can effectively increase the range of reflection adjustment of the incident light, thereby increasing the reflection effect. Furthermore, since the first reflecting surface 22311 and the second reflecting surface 22312 are angled, the depth of the concave edge 2232 needs to be set deeper than that of Example 1. Therefore, the concave edge 2232 of this embodiment is vertically set, and the rest is the same as Example 1, and the effect of Example 1 is also achieved.

[0051] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
