DETAILED DESCRIPTION

[0061] The following will be combined with the drawings in this embodiment of the utility model to clearly and completely describe the technical solution in this embodiment of the utility model. 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.

[0062] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back...) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0063] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features.

[0064] See also Figures 1 to 31 , an embodiment of the utility model provides a light guide structure of an atmosphere lamp.

[0065] Example 1

[0066] like Figures 1 to 10 As shown, the light guide structure of the atmosphere lamp of this embodiment includes: a PCB board 1, on which a plurality of groups of equidistantly arranged LED lamp beads 11 are arranged;

[0067] This embodiment also provides a light guide 2, such as Figures 1 to 3 The light guide 2 includes a light emitting portion 21 and a light incident portion 22. The PCB board 1 is arranged on one side of the light incident portion 22. A light emitting surface 211 is formed on the end face of the light emitting portion 21. A light incident surface 221 is provided on the light incident portion 22. A concave light scattering structure 222 is formed on the light incident surface 221. Specifically, an embedded groove 23 connected to the concave light scattering structure 222 is opened on the above-mentioned light incident portion 22, and the PCB board 1 can be directly fixed in the embedded groove 23. Of course, in order to install the PCB board 1 more firmly, it can also be fixed for a second time by glue or screws.

[0068] A first bending portion 24 is formed between the light emitting portion 21 and the light incident portion 22. The first bending portion 24 allows the light guide 2 of this embodiment to have a C-shaped structure as a whole, that is, the light emitting portion 21 and the light incident portion 22 are respectively arranged on both sides of the first bending portion 24 and are arranged in parallel, so that the light emitting surface 211 is staggered with the PCB board 1, and a first reflecting surface 241 is formed on the inner wall surface of the first bending portion 24.

[0069] The concave light-scattering structure 222 is an arc-shaped light-scattering surface formed by the concave light-emitting surface 211. The setting direction of the concave light-scattering structure 222 of this embodiment is perpendicular to the setting direction of the light-incoming portion 22. The LED lamp bead 11 is directly opposite to the first reflecting surface 241, so that the light emitted by the LED lamp bead 11 is emitted from the concave light-scattering structure 222. By forming an arc-shaped light-scattering surface, the light-scattering effect of the concave light-scattering structure 222 can be better.

[0070] Preferably, in order to further prevent the light emitting surface 211 from being able to observe the internal structure of the present embodiment, a straight connecting portion 25 is formed between the first bent portion 24 and the light incident portion 22, and the connecting portion 25 makes the light emitting portion 21 and the light incident portion 22 separated from each other, and the direction of the light emitting surface 211 is parallel to the setting direction of the light incident portion 22, so that the light incident portion 22 and the light emitting surface 211 are staggered. Figure 1 As shown, the light emitting surface 211 is arranged horizontally, and the light incident portion 22 is also arranged horizontally, so that the light emitting surface 211 and the light incident portion 22 can be offset, so that the light emitting surface 211 cannot directly observe the internal structure of the light incident portion 22.

[0071] In particular, the first reflective surface 241 includes an optical microstructure 2411 evenly distributed on the inner wall of the bending portion, which adjusts the incident light so that the light can be evenly emitted from the light emitting surface 211. In order to make the incident angle of the light source more reasonable, the optical microstructure 2411 can be a nano-scale microstructure, such as Figure 3 and Figure 7 The shape of the optical microstructure 2411 in the present embodiment is a V-shaped texture, but it can also be Figures 8 to 10 In this embodiment, the optical microstructure 2411, the light incident portion 22, the first bending portion 24 and the light exit portion 21 are integrally formed. The high uniformity of the brightness of the entire light guide can be achieved by adjusting the microstructure optical texture structure on the mold.

[0072] 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 222 , diffuses and staggers the light source through the concave light diffusion structure 222 to form a larger area of ​​light, and then adjusts the light through the optical microstructure 2411 of the first reflective surface 241 so that the light can be reflected uniformly, and finally emitted through the light emitting surface 211 .

[0073] like Figure 4As shown, this embodiment can be directly installed on the inner wall 3 of the automobile body, and a mounting portion 223 is formed by extending from the lower end of the light-entering portion 22. The mounting portion 223 is provided with a connecting screw hole, and can be fixed on the plate of the inner wall of the automobile through screws and the connecting screw holes. There is no need to set up an additional shell 5. Of course, a corresponding adapted shell 5 can also be set up according to actual conditions for independent use. The utility model forms a concave light-scattering structure 222 on the light-entering surface 221, which can diffuse the light incident from the light source to form a larger area of ​​light. A small amount of concave light-scattering structure 222 can be used to obtain a higher luminosity to meet the brightness requirements of the atmosphere lamp. In this way, the number of light sources can be greatly reduced, the light-guiding efficiency can be improved, and the cost can be reduced. The utility model can stagger the light-emitting surface 211 with the light-entering portion 22, thereby achieving the staggering of the PCB board 1 installed on the light-entering portion 22 with the light-emitting surface 211, and the internal structure of the atmosphere lamp cannot be observed from the light-emitting surface 211, thereby improving the overall aesthetics and decorative effect of the interior of the vehicle.

[0074] Example 2

[0075] The difference between this embodiment and embodiment 1 is that Figures 11 to 15 As shown, the setting direction of the concave light-scattering structure 222 of the present embodiment is set parallel to the setting direction of the light incident portion 22. For the setting of the concave light-scattering structure 222, a first supporting platform 224 is set on the light incident portion 22. The first supporting platform 224 is adjacent to the concave light-scattering structure 222. The PCB board 1 is fixedly connected to the first supporting platform 224. The PCB board 1 can be fixedly connected to the first supporting platform 224 by screws / glue or the like.

[0076] In this embodiment, two bending parts are provided in total to smoothly realize the propagation of light. A second bending part 26 is formed between the connecting part 25 and the light incident part 22. The inner wall surface of the second bending part 26 forms a second reflecting surface 261. The first reflecting surface 241 and the second reflecting surface 261 are arranged opposite to each other. The first reflecting surface 241 and the second reflecting surface 261 of this embodiment are both provided with an optical microstructure 2411. Light is emitted from the LED lamp bead 11, and is scattered by the concave light scattering structure 222. Then the light is adjusted and leveled by the first reflecting surface 241 and the second reflecting surface 261 in turn, and finally a uniform and high-brightness light is emitted from the light emitting surface 211. The rest is the same as that of the embodiment 1, and the technical effect of the embodiment 1 is achieved at the same time.

[0077] Example 3

[0078] The difference between this embodiment and embodiment 1 is: Figures 16 to 21In this embodiment, the light emitting portion 21 and the light incident portion 22 do not need to be specially staggered. Only the first bending portion 24 needs to be formed, and the connecting portion 25 does not need to be provided. The first mounting groove 242 is formed at the inner bend of the first bending portion 24, and the middle end of the first bending portion 24 is a flat straight portion 243, so that the first mounting groove 242 formed by the inner bend of the first bending portion 24 has a larger space. A shielding member 4 matching the first mounting groove 242 is installed on the first mounting groove 242. The shielding member 4 blocks the light emitting surface 211 and the light incident portion 22. The shielding member 4 can completely block the light emitting surface 211 and the light incident portion 22, and the structure inside the light guide body cannot be directly observed from the light emitting surface 211.

[0079] In this embodiment, a V-shaped reflective structure 225 for reflecting large-angle light is formed between two adjacent concave light-scattering structures 222, and an optical microstructure 2411 is provided on the V-shaped reflective structure 225. The V-shaped reflective structure 225 can adjust the large-angle light emitted from the concave light-scattering structure 222 and re-enter the visible track of the light-emitting surface 211, thereby avoiding the situation where the large-angle light cannot be emitted from the light-emitting surface 211, and improving the brightness of the light emitted from the light-emitting surface 211.

[0080] Preferably, in this embodiment, the two ends of the first bending portion 24 form a first reflecting surface 241 and a fifth reflecting surface 244, respectively. A fourth bending portion 27 is provided between the first bending portion 24 and the light emitting portion 21 so that the light emitting portion 21 can be arranged horizontally. A sixth reflecting surface 271 is provided on the fourth bending portion 27. In this embodiment, the first reflecting surface 241, the fifth reflecting surface 244 and the sixth reflecting surface 271 are all provided with an optical microstructure 2411, such as Fig. 20 and Fig.21 As shown, the LED lamp bead 11 emits a light source, which is diffused by the concave light-scattering structure 222. At the same time, the large-angle light is readjusted and reflected by the V-shaped reflection structure 225 to the folding area where the light is weaker, so that the overall light is propagated more evenly. Then, the first reflection surface 241 is used for secondary adjustment and leveling and reflected to the fifth reflection surface 244. The fifth reflection surface 244 is adjusted for the third time and leveled and reflected to the sixth reflection surface 271 for the last light leveling adjustment, and then evenly emitted from the light-emitting surface 211. The straight portion 243 at the middle end helps to keep the light in a stable direction in the bending portion, and the first reflection surface 241 and the fifth reflection surface 244 at both ends can guide and control the propagation path of the light. Such a design can ensure that the light maintains a certain angle and direction during the bending process, so that the light can be effectively reflected and propagated.

[0081] In order to improve the adaptability of this embodiment and enable it to be suitable for different atmosphere lamp structures, this embodiment also includes a shell 5, which may include an upper shell 51 and a lower shell 52 that are engaged with each other, and a third mounting groove 521 for mounting an LED board is arranged on the lower shell 52, and the LED board is fixed in the third mounting groove 521, and the light input portion 22 is inserted into the third mounting groove 521 so that the concave light scattering structure 222 is opposite to the LED lamp bead 11, and a second supporting platform 522 is arranged at the front end of the lower shell 52 away from the third mounting groove 521, and the light output portion 21 is hung on the second supporting platform 522, and the light output surface 211 is flush with the outer edge of the lower shell 52, and the upper shell 51 is also provided with a clamping portion 511 that matches the position of the second supporting platform 522, and the clamping portion 511 can clamp and fix the light output portion 21 with the second supporting platform 522 during assembly. In this embodiment, the shielding member 4 is integrally formed with the lower housing 52, and the shielding member 4 is inserted into the first mounting groove 242 and abuts against the inner wall of the first mounting groove 242, so as to shield the light-entering portion 22 and the internal structure of the PCB board 1 and the like, and also support the light guide 2. Finally, through the assembly of the upper housing 51 and the lower housing 52, the inner wall of the upper housing 51 and the fixing portion 511 cooperate to fix the light guide 2. Other aspects are the same as those of the first embodiment, and the effects of the first embodiment are also achieved.

[0082] Example 4

[0083] The difference between this embodiment and embodiment 1 is: Figure 22 to Figure 26 In this embodiment, the light emitting portion 21 and the light incident portion 22 do not need to be specially staggered, and there is no need to set a connecting portion 25. It is only necessary to form a first bending portion 24. The first bending portion 24 is a V-shaped arc-shaped bending structure. A third arc-shaped bending portion 28 is formed between the first bending portion 24 and the light emitting portion 21, so that the light emitting portion 21 can be set horizontally, thereby ensuring that the light emitting surface 211 is set straight, thereby enhancing the light emitting effect of the light emitting surface 211; a first mounting groove 242 is formed at the inner bend of the first bending portion 24, and a shielding member 4 matching the first mounting groove 242 is installed on the first mounting groove 242. The shielding member 4 blocks the light emitting surface 211 and the light incident portion 22. The shielding member 4 can completely block the light emitting surface 211 and the light incident portion 22, and the structure inside the light guide cannot be directly observed from the light emitting surface 211.

[0084] In order to enhance the effective treatment of the wide-line diffusion of the concave light-scattering structure 222, a V-shaped reflection structure 225 for reflecting large-angle light is formed between two adjacent concave light-scattering structures 222, and an optical microstructure 2411 is provided on the V-shaped reflection structure 225. The V-shaped reflection structure 225 can adjust the large-angle light emitted by the concave light-scattering structure 222 and re-enter the visible track of the light-emitting surface 211, thereby avoiding the situation where the large-angle light cannot be emitted from the light-emitting surface 211, and at the same time, the large-angle light is reflected to a place with lower brightness, so as to make the light spot uniform.

[0085] The first curved portion 24 and the light incident portion 22 form a fourth curved portion 29, which is bent downward to adapt to different installation positions. The fourth curved portion 29 forms a fourth reflecting surface 291 disposed opposite to the first reflecting surface 241, and the fourth reflecting surface 291 reflects the incident light from the light incident portion 22 to the first reflecting surface 241. The third curved portion 28 forms a third reflecting surface 281 disposed opposite to the first reflecting surface 241, and the third reflecting surface 281 reflects the light reflected from the first reflecting surface 241 to the light emitting surface 211. The first reflecting surface 241, the third reflecting surface 281 and the fourth reflecting surface 291 of this embodiment are all provided with light microstructures to enhance the light adjustment and leveling performance.

[0086] By enhancing the reflection effect of the light reflected from the first reflection surface 241 inside the atmosphere lamp, the reflected light can be better focused, thereby improving the flexibility and applicability of the atmosphere lamp.

[0087] In order to improve the adaptability of this embodiment and enable it to be suitable for different atmosphere lamp structures, this embodiment also includes a shell 5, which may include an upper shell 51 and a lower shell 52 that are engaged with each other, and a second mounting groove 523 for mounting the light guide 2 is provided on the lower shell 52, and a light-emitting through hole for clamping the light-emitting part 21 is opened on the side edge of the lower shell 52. In particular, the shielding member 4 of this embodiment is integrally formed with the upper shell 51, and the shielding member 4 is an L-shaped structure, so that a third mounting groove 521 is formed between one end of the shielding member 4 and the upper shell 51, and the above-mentioned LED board is fixed on the third mounting groove 521. In this embodiment, the inner bend of the first bending portion 24 is downward, so that the light input portion 22 can be projected into the third mounting groove 521, ensuring that the LED lamp beads 11 on the PCB board 1 can face the concave light-scattering structure 222. The other end of the shielding member 4 away from the upper shell 51 matches the shape of the first mounting groove 242 and can be completely inserted into the first mounting groove 242, facing the light-emitting surface 211 to achieve shielding of the light-emitting surface 211. The shell 5 described in this embodiment can protect the light-guiding structure, and can be applied to different scenes and positions, thereby improving the adaptability of the utility model. The rest is the same as that of Example 1, and the effect of Example 1 is also achieved.

[0088] Example 5

[0089] The difference between this embodiment and embodiment 4 is: Figures 27 to 31 The fourth arc-shaped bending portion 29 of this embodiment is bent upward, so that the light-entering portion 22 and the light-emitting portion 21 are nearly on the same horizontal line, and in particular, a seventh reflection surface 292 is formed on the lower end surface of the fourth arc-shaped bending portion 29, and an optical microstructure 2411 is also disposed on the seventh reflection surface 292. The setting direction of the concave light-scattering structure 222 is toward the light-emitting surface 211. The light path of this embodiment is emitted from the LED lamp bead, passes through the seventh reflection surface 292, the fourth reflection surface 291, the first reflection surface 241 and the third reflection surface 281 in sequence, and after being adjusted and aligned by the optical microstructure 2411 disposed on the above-mentioned reflection surfaces, the light beam is uniformly emitted from the light-emitting surface.

[0090] In this embodiment, the shielding member 4 is integrally formed with the inner wall of the lower shell 52. The shielding member 4 is an upwardly protruding cone structure as a whole. The first mounting groove 242 is directly mounted on the shielding member 4, so that the spacing between the light-emitting portion 21 and the light-entering portion 22 can be achieved, so that the light-emitting surface 211 cannot observe the light-entering portion 22 and the structure behind the shielding member 4. In this embodiment, a second mounting groove 523 for wrapping the light guide and a third mounting groove 521 for mounting the PCB board 1 are formed on the upper shell 51. The PCB main board is fixed in the third mounting groove 521, and the position of the PCB main board is placed on one side of the light-entering portion 22, so that the LED lamp bead 11 can face the concave light-scattering structure 222 of the light-entering surface 221 in the vertical direction. Its light source direction, the number of reflecting surfaces and other structures are the same as those of Example 3, and the effect of Example 3 is also achieved.

[0091] 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.
