[0043] Reference below Figures 1-9 The light guiding system 100 according to the embodiment of the present invention is described. By setting the cooperation between the light source module 1, the light guide 2 and the diffuser 3, the light can be propagated through the light guide 2 and the diffuser 3 in sequence, and the normal of the light incident surface 211 is set to intersect with the normal of the main light emitting surface 231, which can change the propagation direction of the light from the entrance to the exit to obtain the light emitting direction required by different requirements, and the diffuser 3 can be used to improve the uniformity and light emitting range of the light to improve the light emitting effect, thereby changing the environmental atmosphere to enhance the user experience, and the structure is simple and the use effect is good.

[0044] like Figures 1-9 As shown, a light guide system 100 according to an embodiment of the present invention includes: a light source module 1 , a light guide member 2 and a diffuser 3 .

[0045] It should be noted that the light guide system 100 in this embodiment is a closed light guide system 100, which can be applied to the vehicle's ambient light. The ambient light includes a reflective ambient light and a direct ambient light. Different types of ambient lights provide users with a comfortable environment and an emotional interaction platform.

[0046] The light source module 1 is the light source of the light guide system 100. The light source module 1 includes a light source and a control module. The light source can be electrically connected to the control module. Through the cooperation of the control module and the light source, different modes of light input can be realized. For example, the light source can be a combination of multiple light sources connected together, or it can be composed of a single light source. Among them, the light source of the light source module 1 can adopt an LED lamp, and the LED lamp is used to emit light to the light guide system 100 to meet the system's light requirements. The LED lamp can be a multi-color light source, or it can be a monochromatic light source. Different settings can provide users with lighting and a comfortable atmosphere. The setting of the LED lamp has the characteristics of low power consumption. Compared with traditional lighting equipment, it can significantly reduce energy consumption and reduce operating costs.

[0047] The light guide 2 includes a light mixing section 21, a coupling area 22 and a conducting portion 23. The light input end of the light mixing section 21 is distributed correspondingly to the light source module 1, and the light output end of the light mixing section 21 is formed with a light input surface 211 distributed correspondingly to the coupling area 22. The coupling area 22 is connected to the conducting portion 23, and the conducting portion 23 is formed with a main light output surface 231.

[0048] Specifically, the light mixing section 21 is sequentially connected to the coupling region 22 and the transmission portion 23. For example, the light mixing section 21, the coupling region 22, and the transmission portion 23 are all configured as a light transmission pipeline. The inlet end of the light mixing section 21 is detachably connected to the light source module 1, allowing light from the light source module 1 to pass into the light mixing section 21. The outlet end of the light mixing section 21 is provided with a light entrance surface 211. The light entrance surface 211 is arranged correspondingly with the coupling region 22, allowing light within the light mixing section 21 to enter the coupling region 22 from the light entrance surface 211, thereby changing the propagation path of the light within the coupling region 22. The coupling region 22 is also connected to the transmission portion 23, allowing light within the coupling region 22 to enter the transmission portion 23. The transmission portion 23 is formed with a main light exit surface 231 to output the light within the transmission portion 23. In this way, the light source module 1 can transmit light to the light guide 2, and light can be transmitted and output within the light guide 2.

[0049] Among them, the conductive portion 23 is used to transmit and guide light, and the main light-emitting surface 231 is used for the main output of light. The normal of the light-entering surface 211 intersects the normal of the main light-emitting surface 231, that is, the normal of the light-entering surface 211 is not parallel to the normal of the main light-emitting surface 231. This arrangement can change the propagation direction of light from the entrance to the exit to meet the required light-emitting direction, and can save the layout space of the entire light-guiding system 100 within the existing space. In actual design, the normal of the light-entering surface 211 can be perpendicular to the normal of the main light-emitting surface 231, or the angle between the two can be less than 90°, etc. Its arrangement is diverse and can be flexibly selected according to actual light output requirements and spatial layout.

[0050] The main light exit surface 231 is correspondingly distributed with the diffusion member 3, wherein the diffusion member 3 has the function of diffusing light rays, and the diffusion member 3 is correspondingly arranged on the light exit side of the main light exit surface 231, so that the light rays of the main light exit surface 231 enter the diffusion member 3, and after being diffused by the diffusion member 3, the light rays can be uniformly output, and the output range of the light rays can be improved.

[0051] Therefore, by setting the cooperation among the light source module 1, the light guide member 2 and the diffusion member 3, the light rays can be sequentially transmitted through the light guide member 2 and the diffusion member 3, and the normal line of the light entrance surface 211 and the normal line of the main light exit surface 231 intersect, so that the propagation direction of the light rays from the entrance to the exit can be changed to obtain different required light exit directions, and the uniformity and the range of the light exit can be improved by the diffusion member 3 to improve the light exit effect, thereby changing the environment atmosphere and improving the user's use experience, and the structure is simple and the use effect is good.

[0052] In some embodiments, the light guide system 100 has a first direction, a second direction and a third direction, the first direction, the second direction and the third direction intersect with each other, that is, the first direction intersects with the second direction and the third direction respectively, and the second direction intersects with the third direction, the first direction, the second direction and the third direction can be set to vertically intersect with each other, or can be set not to vertically connect. The setting mode can be flexibly selected according to actual light exit requirements and space arrangement. Among them, the first direction, the second direction and the third direction can be set as three directions of a space coordinate system, similar to X axis, Y axis and Z axis.

[0053] Among them, the light entrance surface 211 is adapted to enter light from one of the first direction and the second direction, and the main light exit surface 231 is adapted to exit light from one of the first direction and the third direction, and the light entrance direction of the light entrance surface 211 is different from the light exit direction of the main light exit surface 231.

[0054] That is, the light entrance surface 211 can enter light from the first direction, or can enter light from the second direction, and the main light exit surface 231 can exit light from the first direction, or can exit light from the third direction, so that when the light entrance surface 211 enters light from the first direction and the main light exit surface 231 exits light from the third direction, when the light entrance surface 211 enters light from the second direction, the main light exit surface 231 can exit light from the first direction or from the third direction, and through the above various setting modes, the light entrance and light exit in various directions can be realized to meet different use requirements.

[0055] Therefore, through the above setting, different coupling modes of different light entrance directions and light exit directions can be realized, the intensity of light transmission can be improved, the problems of low efficiency, uneven brightness at the bending and splicing parts of the soft light guide strip system can be solved. And the structure of the closed light guide system 100 of various types can change the light path propagation, so that it can be flexibly selected according to the actual situation, has higher adaptability, and has wide application range.

[0056] In some embodiments, the coupling regions 22 and the conducting sections 23 are at least one group, and the at least one group of coupling regions 22 and the at least one group of conducting sections 23 are jointly configured as a closed-loop light guide structure.

[0057] Specifically, the number of the coupling regions 22 and the conducting sections 23 is the same, and the coupling regions 22 and the conducting sections 23 are correspondingly distributed along the light propagation direction, wherein the at least one group of coupling regions 22 and the at least one group of conducting sections 23 are connected in a closed loop and can be jointly configured as a closed-loop light guide structure. In actual design, the length of the conducting section 23 can be set to be greater than the length of the coupling region 22, so that the conducting section 23 forms multi-directional light output, thereby increasing the light output range and improving the overall light output range and uniformity of the light guide system 100.

[0058] The coupling regions 22 and the conducting sections 23 can be provided in one group, two groups, three groups, etc.

[0059] The closed-loop light guide structure is located in the plane formed by the second direction and the third direction, wherein the first direction intersects with the second direction and the third direction pairwise. In this way, the coupling regions 22 and the conducting sections 23 are arranged in a closed loop in the plane formed by the second direction and the third direction, so that the closed-loop light guide structure intersects with the first direction, and the arrangement of the closed-loop light guide structure in space can be realized, thereby meeting specific spatial arrangement requirements.

[0060] In this way, through the above arrangement, the light-in direction and the light-out direction of the closed-loop light guide structure can be set to be multiple, so as to increase the types of structures for changing the light propagation direction.

[0061] In some embodiments, the light mixing section 21 is connected to the coupling region 22 along the first direction, and the light-in surface 211 is adapted to in-light along the first direction, and the main light-out surface 231 is adapted to out-light along the third direction.

[0062] In this way, the light can enter the coupling region 22 along the first direction, and then enter the conducting section 23 through the coupling region 22, and out-light along the third direction at the main light-out surface 231, so as to realize the light path propagation of in-light along the first direction and out-light along the third direction.

[0063] Specifically, the light mixing section 21 can be set to extend along the first direction, so as to realize the light propagation along the first direction in the light mixing section 21. The light-in surface 211 of the light-out end of the light mixing section 21 is set to be in communication with the coupling region 22 along the first direction, i.e., the normal line of the light-in surface 211 is distributed along the first direction, so as to realize the in-light along the first direction at the light-in surface 211. The normal line of the main light-out surface 231 of the conducting section 23 is distributed along the third direction, so as to realize the out-light along the third direction at the main light-out surface 231, thereby changing the propagation path of the light.

[0064] Thus, by the coupling mode of the first direction light-in and the third direction light-out, the change of the light from the first direction to the third direction can be realized to control the light to transfer along the set direction, and the use requirement of the customer can be met.

[0065] In addition, the light mixing section 21 can be arranged to extend along the first direction only, and the light-in surface 211 and the coupling region 22 are connected along the first direction, so as to ensure that the light enters the coupling region 22 along the first direction.

[0066] In some embodiments, the coupling region 22 has a first light splitting surface 221 and a second light splitting surface 222, the first light splitting surface 221 and the second light splitting surface 222 are distributed along the second direction and are inclined relative to the first direction, and the first light splitting surface 221 and the second light splitting surface 222 are used to guide the light at the light mixing section 21 towards the conducting part 23.

[0067] In this way, the light entering the coupling region 22 can be guided to the conducting part 23 through the first light splitting surface 221 and the second light splitting surface 222, respectively, the transfer of the light between the light mixing section 21 and the conducting part 23 can be realized, and the propagation path of the light from the light mixing section 21 to the conducting part 23 can be changed.

[0068] Specifically, as shown in Figure 2 and Figure 3 , the first light splitting surface 221 and the second light splitting surface 222 are oppositely distributed along the second direction, and can be symmetrically distributed along the second direction, and the first light splitting surface 221 and the second light splitting surface 222 are both inclined relative to the first direction, and the first light splitting surface 221 and the second light splitting surface 222 are connected, and both are inclined from the direction close to each other to the direction away from each other in the direction away from the light-in surface 211, so that the light entering the coupling region 22 from the light-in surface 211 can be reflected by the first light splitting surface 221 and the second light splitting surface 222 and then enter the conducting part 23, and the structure is reasonable and the light guiding is reliable.

[0069] Thus, by the above arrangement, a large amount of light entering the coupling region 22 from the light mixing section 21 can be guided into the conducting part 23 through the reflection of the first light splitting surface 221 and the second light splitting surface 222, the change of the transfer path of the light from the coupling region 22 to the conducting part 23 can be realized, and the amount of light propagation from the coupling region 22 to the conducting part 23 can be improved, so as to improve the light guiding capability of the light guiding system 100.

[0070] It should be noted that the included angles between the first light splitting surface 221 and the second light splitting surface 222 and the vertical direction are both 45°, and can also be set to other angles, which are greater than the critical angle of total reflection, so as to improve the total reflection capability of light, and the proportions of the first light splitting surface 221 and the second light splitting surface 222 are the same, so that the reflection capabilities of the two are the same, and uniform light splitting is achieved. If the propagation direction is an angle within 10° with the vertical direction, the uniformity can be obtained by adjusting the included angles between the first light splitting surface 221 and the second light splitting surface 222 and the vertical direction and the proportions of the first light splitting surface 221 and the second light splitting surface 222.

[0071] In some embodiments, the coupling region 22 also has a third light splitting surface 223 and a side light output surface 224, the third light splitting surface 223 is connected with the first light splitting surface 221 and the second light splitting surface 222 respectively, and a part of the third light splitting surface 223 is distributed along the third direction with the first light splitting surface 221 and another part is distributed along the third direction with the second light splitting surface 222, the third light splitting surface 223 is adapted to guide light to the side light output surface 224, the side light output surface 224 is distributed corresponding to the diffusion member 3, and the side light output surface 224 is provided with a side light guide tooth.

[0072] In this way, part of the light entering the coupling region 22 can be guided to the corresponding side light output surface 224 through the third light splitting surface 223, so that the light can enter the coupling region 22 from the mixed light section 21 and be guided out of the light.

[0073] Specifically, as shown in Figure 2 and Figure 3 The third light splitting surface 223 is connected with the first light splitting surface 221 and the second light splitting surface 222, forming three light splitting surfaces of the coupling region 22, wherein in the third direction, the third light splitting surface 223 is connected with the first light splitting surface 221 and the second light splitting surface 222 on the side close to the diffusion member 3, and the third light splitting surface 223 is in a closed state with the first light splitting surface 221 and the second light splitting surface 222 respectively, so as to avoid light leakage along the first direction, the coupling region 22 also includes a side light output surface 224 distributed opposite to the third light splitting surface 223, so that part of the light in the coupling region 22 can be output along the side light output surface 224, and the side light output surface 224 is distributed corresponding to the diffusion member 3, so that the light can be transmitted out after being diffused by the diffusion member 3, and the side light output surface 224 can be provided with a side light guide tooth, and the size, angle and depth of the side light guide tooth can be adjusted when setting, so as to change the propagation path of the light at the side light output surface 224, so as to realize uniform light output of the side light output surface 224.

[0074] The side light guide tooth can be provided as a plurality of teeth, and the plurality of side light guide teeth are distributed at intervals, which is beneficial to improving the uniformity of light output of the side light output surface 224. The side light guide tooth can be provided as a convex tooth or a concave tooth.

[0075] Thus, by the above arrangement, most of the light entering the coupling area 22 is transmitted to the conducting part 23 through the first and second light splitting surfaces 221 and 222 respectively, and a part of the light can be refracted to the side light exit surface 224 through the third light splitting surface 223, so that the light output in the coupling area 22 can be realized, and the normal light output of the coupling area 22 and the conducting part 23 can be ensured, thereby improving the light guiding capability of the light guiding system 100.

[0076] It should be noted that the light output by the third light splitting surface 223 after refracting part of the light to the side light exit surface 224 can be adjusted by adjusting the proportion of the third light splitting surface 223, i.e., the proportions of the first, second and third light splitting surfaces 221, 222 and 223 can be adjusted according to the actual required light output intensity.

[0077] In some embodiments, the light mixing section 21, the coupling area 22, the conducting part 23 and the light source module 1 are one, and the two ends of the coupling area 22 are connected to the two ends of the conducting part 23 respectively.

[0078] In this way, by respectively arranging one light mixing section 21, one coupling area 22, one conducting part 23 and one light source module 1, a single-lamp-group light guiding system 100 can be formed, which can be adapted to a scene with a relatively short light guiding path and a single shape, and has a simple structure and is more convenient to assemble.

[0079] Specifically, as shown in FIG. 1, the light guiding system 100 includes a light mixing section 21, a coupling area 22, a conducting part 23 and a light source module 1. Figure 4 As shown in FIG. 1, a structure schematic diagram of the single-lamp-group light guiding system 100 is shown, and the overall structure can be circular in shape, wherein the coupling area 22 is connected to the light exit end of the light mixing section 21, the conducting part 23 has the maximum extension length, and the conducting part 23 extends along the circle, and the two ends of the coupling area 22 are connected to the two ends of the conducting part 23, forming a closed light guiding system 100 with a single shape, so that the conducting part 23 and the coupling area 22 form a circular light exit range, to adapt to the requirement of a relatively short light propagation path in a single scene. The conducting part 23 can be circular in cross section, square in cross section or irregular in cross section.

[0080] The shape of the single-lamp-group light guiding system 100 can also be elliptical, etc.

[0081] Alternatively, the light mixing section 21, the coupling area 22, the conducting part 23 and the light source module 1 are multiple and correspond to each other, and the multiple coupling areas 22 and the multiple conducting parts 23 are distributed in a staggered manner in the circumferential direction of the closed-loop light guiding structure.

[0082] In this way, by respectively arranging multiple light mixing sections 21, multiple coupling areas 22, multiple conducting parts 23 and multiple light source modules 1, a multi-lamp-group light guiding system 100 can be formed, which can be adapted to a scene with a relatively long light guiding path and a requirement for more light.

[0083] Specifically, the light mixing section 21, the coupling region 22, the conducting part 23 and the light source module 1 can be provided as two, as shown in Figure 1 and Figure 2 As shown in the structure diagram of the light guide system 100 of two light groups, the overall structure can be provided as a long strip shape, wherein the two coupling regions 22 are respectively connected with the light emitting ends of the corresponding light mixing sections 21, and the two conducting parts 23 can be provided with the same extension length, and the two coupling regions 22 and the two conducting parts 23 are staggered in the circumferential direction of the closed loop light guide structure, that is, the two ends of one coupling region 22 are respectively connected with the light entering ends of the two conducting parts 23, and the two ends of one conducting part 23 are respectively connected with the two coupling regions 22, so that the two light source modules 1 can emit light at the same time, and the light can be guided to the two conducting parts 23 through the corresponding coupling regions 22, and two beams of light can be respectively transmitted out, which reduces the transmission path of a single beam of light, saves the light transmission time, and does not change the total light propagation path to adapt to the scene requirement of a longer light propagation path.

[0084] Among them, the light mixing section 21, the coupling region 22, the conducting part 23 and the light source module 1 can also be provided as three, four, etc.

[0085] Therefore, through the above setting, the light guide system 100 can form a closed loop light emitting path, effectively emit light in the circumferential direction of the closed light guide system 100, and set multiple light emitting structures to improve the light emitting uniformity of multiple conducting parts 23, thereby improving the overall light emitting effect of the light guide system 100.

[0086] In some embodiments, the light mixing section 21 is connected to the coupling region 22 along the second direction, and the light entering surface 211 is adapted to enter light along the second direction, and the main light emitting surface 231 is adapted to emit light along the third direction.

[0087] In this way, the light can enter the coupling region 22 along the second direction, and enter the conducting part 23 through the coupling region 22, and emit light along the third direction at the main light emitting surface 231, so as to realize the light path propagation of entering light along the second direction and emitting light along the third direction.

[0088] Specifically, the light mixing section 21 can be provided to extend along the second direction, so as to realize the propagation of light along the second direction in the light mixing section 21, and the light entering surface 211 of the light emitting end of the light mixing section 21 is in communication with the coupling region 22 along the second direction, that is, the normal line of the light entering surface 211 is distributed along the second direction, so as to realize the light entering along the second direction at the light entering surface 211, and the normal line of the main light emitting surface 231 of the conducting part 23 is distributed along the third direction, so as to realize the light emitting along the third direction at the main light emitting surface 231, so as to change the propagation path of the light.

[0089] Thus, by the coupling mode of the second direction light-in and the third direction light-out, the change of light from the second direction to the third direction can be realized to control the transmission of light along the set direction, meeting the customer's use needs.

[0090] In addition, the light mixing section 21 can be arranged to extend along the second direction only, and the light-in surface 211 and the coupling region 22 are connected along the second direction, so as to ensure that the light enters the coupling region 22 along the second direction.

[0091] In some embodiments, the coupling region 22 is formed with a total reflection surface 225, and at least part of the light at the light mixing section 21 is reflected to the conducting part 23 through the total reflection surface 225.

[0092] In this way, at least part of the light entering the coupling region 22 is guided to the conducting part 23 through the total reflection surface 225, the transmission of light between the light mixing section 21 and the conducting part 23 can be realized, and the propagation path of light from the light mixing section 21 to the conducting part 23 can be changed.

[0093] Specifically, as shown in Figure 6 and Figure 7 the light mixing section 21 can extend along an arc-shaped section, and the light-out end of the light mixing section 21 is tangentially connected with the coupling region 22, so that the light enters the coupling region 22 along the second direction, and the total reflection surface 225 is arranged in the coupling region 22, so that more light in the coupling region 22 enters the conducting part 23 through the total reflection surface 225, and in actual design, the coupling region 22 can be thickened and the curvature of the total reflection surface 225 can be adjusted to make more incident light satisfy the total reflection condition, so as to continue to propagate in the coupling region 22. The conducting part 23 can be arranged to have a circular cross section, a square cross section or a special-shaped cross section.

[0094] Thus, the light-out problem and the space problem of the light guide 2 cannot make the light-in direction be the absolute third direction, and the light-in direction is a synthetic direction, i.e., the light entering the coupling region 22 can be decomposed into the second direction and the third direction, and the light in the two directions can be more reflected to the conducting part 23 through the total reflection surface 225, the transmission amount of light is improved, the direct leakage of light in the coupling region 22 is reduced, the obvious bright spot is avoided on the light-out surface of the coupling region 22, and the phenomenon that the light-out surface intensity of the coupling region 22 is obviously weakened is reduced. In addition, the arrangement mode of the light mixing section 21 can occupy more space in the second direction and the third direction, reduce the space occupied in the first direction, make the overall structure more compact, and be conducive to the integrated arrangement with other structures.

[0095] In some embodiments, the total reflection surface 225 is correspondingly distributed with the diffusion member 3, and the total reflection surface 225 is provided with a first light guide tooth 2251.

[0096] Specifically, the diffusion member 3 is located on the opposite side of the total reflection surface 225, and the diffusion member 3 is also distributed opposite to the illuminated surface 4, so that the light can be scattered through the diffusion member 3 and then irradiated on the illuminated surface 4, so that the illuminated surface 4 achieves a uniform reflection effect. As shown in Figure 7 In the light guide system 100 of the second direction light entering and the third direction light exiting, the length of the coupling area 22 is relatively long, and the total reflection surface 225 can be provided with a first light guide tooth 2251. When the first light guide tooth 2251 is provided, the size, angle and depth of the first light guide tooth 2251 can be adjusted, and the light propagation path of the total reflection surface 225 can be changed to make the total reflection surface 225 uniformly emit light. The length of the coupling area 22 and the thickening thickness can be adjusted according to the structure and space requirements. The diffusion member 3 is an optical member for weakening the light emitting effect of the light guide tooth, which can be a fogging member with internal scattering particles, a transparent member with frosted surface, or other surface treatment process members.

[0097] The first light guide tooth 2251 can be provided in multiple, and the multiple first light guide teeth 2251 are distributed at intervals, which is beneficial to improve the uniformity of the light emitted by the total reflection surface 225. The first light guide tooth 2251 can be provided as a convex tooth or a concave tooth.

[0098] Therefore, through the above setting, most of the light entering the coupling area 22 can be transmitted to the transmission part 23 through the total reflection surface 225, and a part of the light can be reflected to the light exit side of the coupling area 22 through the total reflection surface 225. The light output in the coupling area 22 can be realized, and the normal light emission of the coupling area 22 and the transmission part 23 can be ensured to improve the light guide capability of the light guide system 100.

[0099] In some embodiments, the coupling area 22 and the transmission part 23 are one, and the light mixing section 21 and the light source module 1 are two and are distributed one by one.

[0100] Specifically, the number of light source modules 1 matches the number of light mixing sections 21, as shown in Figure 5 and Figure 6 Two light source modules 1 are connected to the light entering ends of the two light mixing sections 21, and the light exiting ends of the two light mixing sections 21 are connected to one coupling area 22 respectively, and the two ends of the coupling area 22 are communicated with the two ends of the transmission part 23 respectively, so as to form a closed light guide system 100.

[0101] Further, the two light source modules 1 emit light at the same time, and two beams of light enter the coupling area 22 from the two ends of the coupling area 22, and through the reflection of the total reflection surface 225, the light can be reflected to the transmission part 23 in two directions respectively, and two beams of light are transmitted respectively, which reduces the transmission path of a single beam of light, saves the light transmission time, and does not change the total light propagation path, so as to adapt to the scene requirement of long light propagation path.

[0102] Thus, by the above setting, the light guide system 100 forms a closed loop light emitting path, which can realize effective light emission in the circumferential direction of the closed light guide system 100, and the two sets of light emitting structures can improve the light emitting uniformity of the two sets of transmission parts 23, thereby improving the overall light emitting effect of the light guide system 100.

[0103] In some embodiments, the light mixing section 21 is connected to the coupling region 22 along the second direction, the light entrance surface 211 is adapted to enter light along the second direction, and the main light exit surface 231 is adapted to emit light along the first direction.

[0104] In this way, the light can enter the coupling region 22 along the second direction and enter the transmission part 23 through the coupling region 22, and the light can be emitted along the first direction at the main light exit surface 231, which can realize the light path propagation of the light entering along the second direction and emitting along the first direction.

[0105] Specifically, the light mixing section 21 can be arranged to extend along the second direction, which can realize the light propagation along the second direction in the light mixing section 21, and the light entrance surface 211 of the light emitting end of the light mixing section 21 is connected to the coupling region 22 along the second direction, i.e. the normal line of the light entrance surface 211 is distributed along the second direction, so as to realize the light entering along the second direction at the light entrance surface 211, and the normal line of the main light exit surface 231 of the transmission part 23 is distributed along the first direction, so as to realize the light emitting along the first direction at the main light exit surface 231, so as to change the propagation path of the light.

[0106] Thus, by the coupling mode of the light entering along the second direction and the light emitting along the first direction, the change of the light from the second direction to the first direction can be realized, so as to control the light to propagate along the set direction, which can meet the use needs of customers.

[0107] In addition, the light mixing section 21 can also be arranged to not only extend along the second direction, but only need to be connected to the coupling region 22 along the second direction at the light entrance surface 211, so as to ensure that the light enters the coupling region 22 along the second direction.

[0108] In some embodiments, the wall thickness of the coupling region 22 is greater than the wall thickness of the transmission part 23, such as Figure 8 and Figure 9As shown, the light mixing section 21 can be configured to extend along the third direction first and then extend along the arc-shaped section to be connected with the coupling area 22, so that the light entering the coupling area 22 can be decomposed into the second direction and the third direction, the wall thickness of the coupling area 22 is set to be large, and a total reflection surface 225 is arranged in the coupling area 22, the total reflection surface 225 has a certain curvature, which can make the light in the coupling area 22 be reflected into the conducting part 23 more, and the wall thickness of the conducting part 23 is small, which can make the light be transmitted in a smaller space, that is, the transmission of the light can be realized, and in the propagation direction of the light, the wall thickness of the coupling area 22 to the conducting part 23 gradually decreases, which can realize the continuity and smoothness of the structure of the coupling area 22 and the conducting part 23, and is beneficial to the processing of the light guide 2. The conducting part 23 can be provided in a circular cross-section, a square cross-section or a special-shaped cross-section.

[0109] The light mixing section 21 can occupy more space in the second direction and the third direction, reduce the space occupied in the first direction, make the overall structure more compact, and be beneficial to the integrated arrangement with other structures.

[0110] It should be noted that if the wall thickness of the coupling area 22 and the wall thickness of the conducting part 23 are set to be equal, part of the light cannot satisfy the total reflection condition at the side of the wall thickness and is directly emitted, which leads to the appearance of bright spots and energy waste. Through the above setting, the light in the coupling area 22 can enter the conducting part 23 more in one direction, and the light interference between adjacent conducting parts 23 can be avoided to affect the light emitting effect, the light transmission amount is improved, and the straight leakage of the coupling area 22 is reduced, the light transmission effect and the propagation stability are improved.

[0111] In some embodiments, the light mixing section 21, the coupling area 22, the conducting part 23 and the light source module 1 are multiple and one-to-one corresponding distribution, and the multiple coupling areas 22 and the multiple conducting parts 23 are staggered distribution in the circumferential direction of the closed loop light guide structure.

[0112] In this way, by respectively setting multiple light mixing sections 21, coupling areas 22, conducting parts 23 and light source modules 1, a multi-lamp group light guide system 100 can be formed, which can be suitable for scenes with longer light guide path and more light demand.

[0113] Specifically, the light mixing section 21, the coupling area 22, the conducting part 23 and the light source module 1 can be provided as two, as shown in Figure 8 and Figure 9 As shown in the structural schematic diagram of the two-lamp group light guide system 100, the overall structure can be provided in a long strip shape, wherein the two coupling areas 22 are respectively connected with the light emitting ends of the corresponding light mixing sections 21, and the two conducting parts 23 can be provided with the same extension length, wherein, as shown in Figure 9As shown, the first coupling area 22, the first conducting part 23, the second coupling area 22 and the second conducting part 23 are connected end to end in sequence, so that the two coupling areas 22 and the two conducting parts 23 are staggered in the circumferential direction of the closed-loop light-guiding structure, and the two conducting parts 23 have different wall thicknesses at the coupling areas 22. In this way, the two light source modules 1 can emit light at the same time, and the two beams of light are guided more to the corresponding conducting parts 23 through the two coupling areas 22, so that the two beams of light can be transmitted separately, reducing the transmission path of a single beam of light, saving light transmission time, and not changing the total light propagation path, so as to adapt to the scene requirements of a longer light propagation path.

[0114] The light mixing section 21 , the coupling region 22 , the conducting portion 23 and the light source module 1 may also be provided in three or four numbers.

[0115] Therefore, through the above-mentioned setting, the light guide system 100 can form a closed-loop light output path, and can realize effective light output of the closed light guide system 100 in the circumferential direction, and set up multiple groups of light output structures, which is beneficial to improve the light output uniformity of multiple groups of conductive parts 23, thereby improving the overall light output effect of the light guide system 100.

[0116] In some embodiments, the main light emitting surface 231 is provided with a main light guide tooth 2311, such as Figure 9 As shown, a main light-emitting surface 231 can be set on the same side of the coupling area 22 and the conducting part 23, which is used to transmit the light in the coupling area 22 and the conducting part 23, and the diffuser 3 is distributed corresponding to the main light-emitting surface 231, so that the light can be scattered by the diffuser 3 and then irradiated on the illuminated surface 4, and a main light-guiding tooth 2311 is provided on the main light-emitting surface 231. When setting, the size, angle and depth of the first light-guiding tooth 2251 can be adjusted, and the light propagation path of the total reflection surface 225 can be changed to make the main light-emitting surface 231 emit light evenly.

[0117] There may be multiple main guiding teeth 2311, which are spaced apart and distributed to improve the uniformity of light emitted from the main light emitting surface 231. The main guiding teeth 2311 may be convex or concave.

[0118] It should be noted that the extension direction of the light mixing section 21 is not only set to a straight extension, but also allows the light emitted by the light source module 1 to be totally reflected back and forth in the light mixing section 21, so that the light color or energy distribution entering the coupling area 22 is as uniform as possible, thereby improving the light input requirements of the incident light.

[0119] The utility model also provides a vehicle.

[0120] According to the vehicle of the utility model embodiment, the light guide system 100 is applied to the vehicle lamp of the vehicle, the vehicle lamp is an important component of the vehicle interior, different light requirements are provided, the light is sequentially propagated through the light guide piece 2 and the diffusion piece 3 through the cooperation between the light source module 1, the light guide piece 2 and the diffusion piece 3, the normal line of the light inlet surface 211 and the normal line of the main light outlet surface 231 intersect, the propagation direction of the light from the entrance to the exit can be changed, the light outlet direction of different requirements is obtained, the uniformity and the light outlet range of the light outlet are improved through the diffusion piece 3, the light outlet effect is improved, the environment atmosphere is changed, and the use experience of the user is improved, and the structure is simple and the use effect is good.

[0121] And through the setting of the above several different coupling modes, and the setting of one or two groups of light source modules 1, the number of light source modules 1 can be reduced, the occupied space is small, the structure is compact, the cost is low, and the light guide piece 2 in the embodiment is a hard light guide piece 2, which can solve the problem of low efficiency of the soft light guide strip system, uneven light at the bending and splicing parts. The closed light guide system 100 formed by different coupling modes can realize uniform light output, improve the light outlet type of the light guide system 100, increase the application range, and according to the influence of the space structure, the placement and light inlet mode of the light source module 1 are not limited to the several cases listed in the embodiment, the corresponding coupling mode can be selected according to the actual situation, and the uniformity of the system can be adjusted by increasing the light shielding structure in the corresponding bright area, or locally adjusting the distance between the hard light guide piece 2 and the diffusion piece 3, or adjusting the local wall thickness or overall thickness of the diffusion piece 3.

[0122] At the same time, the closed light guide system 100 with different coupling modes can be directly used as a direct type atmosphere lamp, and can also be used as a reflection type atmosphere lamp to directly illuminate the illuminated surface 4, so that the illuminated surface 4 realizes uniform effect.
