[0002] A light guide is a structural member used to guide the light of a light source (usually an LED) to where light is needed, such as PMMA (Poly (Methyl Methacrylate)), PC (Polycarbonate resin), etc. The light guide structure has the advantages of flexible shape and high light efficiency, so various light guide materials are often used as atmosphere lights and lighting lights in vehicles.

[0003] However, during the application of the light guide structure in vehicles, due to heat loss during the photoelectric conversion of the light source, especially in the application of high-power light sources, the heat loss is more obvious. And because the light guide structure is close to the light source position, the heat lost by the light source affects the light incident end of the light guide structure, resulting in burning and yellowing of the light incident end. Summary of the Invention

[0004] The embodiment of the utility model provides a light guide system and a vehicle to solve the problem that the light incident end of the light guide structure is burned and yellowed due to heat loss during the photoelectric conversion of the light source.

[0005] In the first aspect of the utility model, a light guide system is provided, which includes a light condensing structure, a light refracting device, a lens structure and a light guide structure.

The driving device can drive the second reflector to deflect to be parallel to the first emitter or the third reflector;

[0006] The light rays of multiple light sources are condensed by the light condensing structure and then enter the first reflector or the third reflector. The incident light is reflected by the first reflector or the third reflector to the second reflector and then reflected by the second reflector to the lens structure. Among them, when the incident light enters the first reflector, the second reflector deflects to be parallel to the first reflector; when the incident light enters the third reflector, the second reflector deflects to be parallel to the third reflector;

[0007] The lens structure focuses the light rays reflected by the second reflector to obtain focused light;

[0010] The reflected light of the second reflector enters the fourth reflector and is reflected by the fourth reflector to the lens structure;

[0011] The lens structure focuses the light reflected by the fourth reflector to obtain the focused light.

[0012] In a possible design, the condensing structure includes a free-form surface or a reflecting surface of a reflector bowl.

[0013] In a possible design, the free-form surface includes an ellipsoidal surface, a parabolic surface, or a spherical arc surface.

[0014] In a possible design, the types of reflectors in the refractive device include a plane mirror or a prism structure.

[0019] In a second aspect, a vehicle is provided, including the light guide system as described above and a plurality of light sources.

[0020] The above-mentioned light guide system and vehicle include a light condensing structure, a light refracting device, a lens structure, and a light guide structure. Among them, the light refracting device includes a first reflector, a third reflector, a second reflector, and a driving device. The driving device can drive the second reflector to deflect to be parallel to the first emitter or the third reflector. The light rays of multiple light sources are condensed by the light condensing structure and then enter the first reflector or the third reflector. The incident light is reflected by the first reflector or the third reflector to the second reflector and then reflected by the second reflector to the lens structure. Among them, when the incident light enters the first reflector, the second reflector deflects to be parallel to the first reflector, and when the incident light enters the third reflector, the second reflector deflects to be parallel to the third reflector. The lens structure focuses the light rays reflected by the second reflector to obtain focused light. The light guide structure guides the focused light to the light emitting area. Since the light condensing structure, the light refracting device, and the lens structure are used in the above steps, especially the first reflector, the second reflector, and the third reflector are used to perform multiple spatial position conversions on the light source, the influence of the heat loss of the light source on the light guide structure is effectively reduced, thereby reducing the risk of burning and yellowing at the light incident end of the light guide structure.

Obviously, the described embodiments are only a part rather than all of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

In the description of the present utility model, unless otherwise specified, the meaning of "a plurality of" is two or more.

[0033] In the description of the present utility model, it should be noted that, unless otherwise clearly defined and limited, the terms "mounted", "connected" and "coupled" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection or an integral connection; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the internal communication of two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0034] In an optical system, a light guide structure often has the characteristics of flexible shape and high light efficiency, so it is widely used in the field of vehicle lamps. However, currently, systems using light guide structures usually have some problems: Firstly, there is a part of heat loss when light is converted into electricity. Especially when the system uses a high-power light source, the influence caused by the heat factor will be more obvious, and in some cases, it will even cause problems such as burning and yellowing at the light input end of the light guide structure; Secondly, in cases where the light guide structure realizes the multiplexing of vehicle lamp functions, usually two or more light sources with different colors are used, or a two-core or three-core light source may be directly adopted. In this case, due to the limitation of the size of the light-emitting chip of the light source, there is usually at least one set of light sources that are out of focus; Thirdly, when the distance between the light source and the light input end of the light guide structure is too far, it will affect the final lighting effect, and when the distance between the light source and the light input end of the light guide structure is too close, it is usually restricted by the heat factor mentioned in the first aspect. Therefore, the light guide structure usually limits the position of the light source, which is not conducive to the display effect of the final product.

[0035] Regarding the problem of lamp multiplexing in the above problems, there are two solutions in the prior art: One is to use a Y-shaped light guide (a light guide with two light input ends), and by changing the color of some structures in one of the light input ends, the multiplexing of lamp functions can be achieved; The other is to obtain the intersection point of light sources distributed in different regions on both sides, and then use a reflector at the intersection point to guide the light from both sides into the light guide structure from the light input end, so as to achieve the multiplexing of lamp functions. But both of these solutions have problems: In the first solution above, since the light source is in a position relatively close to the light input end of the light guide, in this case, the heat loss of the light source will affect the light guide structure. And the color of some structures at the light input end is inconsistent with other parts of the light guide structure, resulting in the inability to form the light guide system integrally; In the second solution above, since the light sources are distributed in different regions on both sides, at least one PCB (Printed Circuit Board) board must exist in the final light guide system.

[0036] Therefore, the embodiment of the present invention provides a light guide system, as Figure 2 shown, which includes a light condensing structure 10, a light refracting device 20, a lens structure 30, and a light guide structure 40, and the detailed description is as follows:

[0037] The light refracting device 20 includes a first reflector 25, a third reflector 27, a second reflector 26, and a driving device, and the driving device can drive the second reflector 26 to deflect to be parallel to the first emitter or the third reflector 27.

[0038] The light rays from multiple light sources are condensed by the condensing structure 10 and then enter the first reflector 25 or the third reflector 27. The incident light is reflected by the first reflector 25 or the third reflector 27 to the second reflector 26, and then reflected by the second reflector 26 to the lens structure 30. Among them, when the incident light enters the first reflector 25, the second reflector 26 deflects to be parallel to the first reflector 25. When the incident light enters the third reflector 27, the second reflector 26 deflects to be parallel to the third reflector 27.

[0039] On the one hand, in this embodiment, the direction of the light rays is changed under the interaction of the first reflector 25, the third reflector and the second reflector 26. The driving device is used to deflect the second reflector 26 to deflect the second reflector 26 according to the incident position of the light rays, so that the second reflector 26 is parallel to the first reflector 25 or the second reflector 26. In this embodiment, it is preferably that the second reflector 26 forms a 45-degree angle with the incident light rays.

[0040] For example, as Figure 2 , the directions of the first reflector 25 and the third reflector 27 remain unchanged. The second reflector 26 can be deflected by the driving device to switch between two angles, one angle is parallel to the first reflector 25, and the other angle is parallel to the third reflector 27. When the first light source 11 is on, the condensing structure 10 focuses the light rays into the first-direction light. The driving device makes the second reflector 26 parallel to the first reflector 25. The first-direction light passes through the first reflector 25, is reflected into the fourth-direction light, and then passes through the second reflector 26 and is reflected into the second-direction light. When the second light source 12 is on, the condensing structure 10 converts the light rays into the first-direction light. The driving device makes the second reflector 26 parallel to the third reflector 27. The first-direction light passes through the third reflector 27, is reflected into the fifth-direction light, and then passes through the second reflector 26 and is reflected into the second-direction light.

[0041] It should be noted that the driving device can change the deflection angle of the second reflector 26 to change the angle of the second reflector 26 so as to keep it parallel to the first reflector 25 or the third reflector 27. This is different from the way of fixing the reflector in the prior art. The driving device makes the second reflector 26 more flexible. No matter where the light source is (such as Figure 2 whether it is the first light source 11 or the second light source 12 in

[0042] On the other hand, in this embodiment, by adjusting the focal length and the opening size of the light condensing structure 10, the light is converted into light in the first direction. When there are multiple first light sources 11, this embodiment can use the light condensing structure 10 to convert all the light into light in the first direction. For example, by adjusting the shape of the free-form surface or the grid curvature of different regions in the light condensing structure 10, the obtained light is converted into light in the first direction. Among them, the light can come from various different lights. In this embodiment, the light is preferably the light of an LED (Light-Emitting Diode).

[0043] It should be noted that the light condensing structure 10 can gather the light from all different positions, which makes this embodiment have no position limitation and no quantity limitation on the first light source 11. This solves the problem in the prior art that a certain specific distance has to be maintained between the light guide structure and the first light source 11.

[0044] The lens structure 30 focuses the light reflected by the second reflector 26 to obtain focused light.

[0045] In this embodiment, by adjusting the focal length of the second reflector 26, the light in the second direction is focused to obtain focused light.

[0046] It should be noted that the lens structure 30 in this embodiment further converges the relatively scattered light in the second direction into focused light. In this whole process, the light emitted from different positions is converted into focused light through multiple reflections, that is, the light emitted by the first light source 11 at any position can be converged into focused light by the light guide system, so that the position limitation of the light guide structure 40 on the first light source 11 no longer exists, so as to make the whole light guide system more flexible and variable.

[0047] The light guide structure 40 guides the focused light to the light emitting area.

[0048] In this embodiment, the shape of the light guide structure 40 is flexible and not fixed. Figures 2 - 5 The shape of the light guide structure 40 is only for illustration and is not the actual light guide shape. This further makes the whole light guide system flexible and variable.

[0049] For example, as Figure 2 , when the first light source 11 is on, the light condensing structure 10 converts the light into light in the first direction, and the refraction device 20 converts the light in the first direction into light in the second direction. Then the lens structure 30 focuses the light in the second direction to obtain focused light, and finally the focused light enters the light guide structure 40 and is guided to the light emitting area.

[0050] It should be noted that, on the one hand, in this embodiment, due to multiple spatial position conversions of light (through the first reflector 25, the second reflector 26, and the third reflector 27), the influence of the heat loss of the first light source 11 on the light guide structure 40 is avoided, thereby reducing the risk of the light guide turning yellow and being burned. On the other hand, in this embodiment, under the treatment of the refractive device 20 and the lens structure 30, the position of the light is flexibly changed. Therefore, the position of the final focused light when it enters the light guide structure 40 from the light incident end is flexibly controllable, which makes the limitation of the light guide structure 40 on the position of the first light source 11 in the prior art no longer exist. On the third hand, since all the light is converted into the first-direction light through the condensing structure 10 in this embodiment, this embodiment can support light sources at multiple different positions (such as Figure 1 the first light source 11 and the second light source 12 in

[0051] In one embodiment, as shown in Figure 4 and Figure 5 , the refractive device 20 further includes a fourth reflector 21;

[0052] The reflected light of the second reflector 26 enters the fourth reflector 21 and is reflected by the fourth reflector 21 to the lens structure 30;

[0053] The lens structure 30 focuses the light reflected by the fourth reflector 21 to obtain the focused light.

[0054] In essence, this embodiment adds a fourth reflector 21, making the shape of the light guide system more flexible.

[0055] For example, when the layout of the light guide system is as shown in Figure 2 and Figure 3 , the lateral first-direction light is converted into the longitudinal third-direction light through the first reflector 25 or the third reflector 27, and then is converted into the lateral second-direction light through the second reflector 26. At this time, the shape of the entire light guide system is lateral. And when the layout of the light guide system is as shown in Figure 4 and Figure 5 , the longitudinal first-direction light is converted into the lateral third-direction light through the first reflector 25 or the third reflector 27, and then is converted into the longitudinal second-direction light through the second reflector 26. Then, the longitudinal second-direction light is converted into the lateral second-direction light through the fourth reflector 21, and the second-direction light is introduced into the lens structure 30. At this time, the shape of the entire light guide system is half longitudinal and half lateral.

[0056] It should be noted that after adding the fourth reflector 21, the structure of the entire light guide system becomes more flexible, and the entire light guide system changes from the original Figure 2 ,Figure 3 The horizontal arrangement of Figure 4 and Figure 5 is changed to the vertical arrangement of

[0057] Therefore, the conversion of light by the fourth reflector 21 is more conducive to the flexible shaping of the light guide system. Figure 4 and Figure 5 Although the fourth reflector 21 is added in

[0058] In one embodiment, the condensing structure 10 includes a free-form surface or the reflecting surface of a reflecting bowl 14. The free-form surface includes an ellipsoidal surface, a parabolic surface, or a spherical arc surface.

[0059] The condensing structure 10 in this embodiment can be the reflecting surface of the reflecting bowl 14 or a free-form surface, which is not limited herein. The reflecting bowl 14 converts light into the first-direction light. Among them, the free-form surface can be an ellipsoidal surface, a parabolic surface, or a spherical arc surface, which is not limited herein.

[0060] It should be noted that the reflecting bowl 14 in this embodiment is mainly used to converge light rays from various different directions, that is, to aggregate all the light rays, so as to be used to change all the light paths in the subsequent steps.

[0061] In one embodiment, the reflector type in the refractive device 20 includes a plane mirror or a prism structure.

[0062] In this embodiment, the reflector is a plane mirror or a prism structure. The reflector includes a first reflector 25, a second reflector 26, a third reflector 27, and a fourth reflector 21.

[0063] It should be noted that the reflectors are all plane mirrors or prism structures, which is different from most of the existing light guide systems that only use one plane mirror or prism structure. In this embodiment, due to the mutual cooperation of the two reflectors, the first-direction light energy can be converted into the second-direction light, so that stable light rays can be focused in the subsequent steps.

[0064] In one embodiment, a reflective film is coated on any one or more of the reflectors of the refractive device 20 or it is set as an aluminized polished surface. The reflector includes a first reflector 25, a second reflector 26, a third reflector 27, and a fourth reflector 21.

[0065] In this embodiment, in order to reduce the loss of light energy, a reflective film can be coated on the reflector, or the reflector can be aluminized and polished.

[0066] It should be noted that in this embodiment, by coating a reflective film on the reflecting mirrors or prism structures of the first reflector 25, the second reflector 26, and the third reflector 27, or performing aluminizing and polishing treatment, the finally obtained structure can better convert all light rays and prevent the loss of light energy during the reflection process.

[0067] In one embodiment, the lens structure 30 includes a plano-convex lens 38.

[0068] Among them, the plano-convex lens 38 focuses light rays into a point. One side of the plano-convex lens 38 is a plane, and the other side is a convex surface.

[0069] It should be noted that the plano-convex lens 38 is used to apply the focus to the optical system and emit the light beam accurately and straight. When the curved part of the plano-convex lens 38 faces the light guide structure 40, the light in the second direction can be clearly focused into a point, so as to guide the finally focused light into the light-emitting area through the light guide structure 40.

[0070] In one embodiment, the convex surface of the plano-convex lens 38 includes a smooth structure, a toothed structure, or a patterned structure.

[0071] In this embodiment, the convex surface of the plano-convex lens 38 can be a smooth structure or an uneven structure, which is not limited here. Its uneven structure includes but is not limited to a toothed structure or a patterned structure.

[0072] It should be noted that in this embodiment, the plano-convex lens 38 can be either a smooth structure or an uneven structure, which makes the material of the lens structure 30 not limited, thus making the entire light guide system have more possibilities.

[0073] In one embodiment, the lens structure 30 exports the intersection point of the focused light to the inside or outside of the light guide structure 40.

[0074] In this embodiment, in order to improve the utilization rate of the light source, the distance between the focus of the light in the second direction focused by the lens structure 30 and the light surface in the light guide structure 40 is adjustable, and its focus position can be inside the light guide structure 40 or outside the light guide structure 40, which is not limited here.

[0075] Example 1, as Figure 2 and Figure 4 shown, the intersection point of the focused light is exported to the outside of the light guide structure 40.

[0076] Example 2, as Figure 3 and Figure 5As shown, the intersection point of the focused light is led into the inside of the light guide structure 40.

[0077] In this embodiment, it is preferably to make the intersection point of the focused light be at a position 2 mm away from the light guide structure 40. This distance may be inside the light guide structure 40 or outside the light guide structure 40. In actual cases, when determining the distance between the focus point and the light guide, factors such as the refractive index of the light guide material and the diameter size of the light guide need to be comprehensively considered, and it needs to be set by combining theoretical evaluation and simulation verification. In principle, it is not recommended to be too far.

[0078] For example, Figure 2 in [reference], the intersection point of the focused light is outside the light guide structure 40, Figure 3 in [reference], the intersection point of the focused light is inside the light guide, Figure 4 in [reference], the intersection point of the focused light is outside the light guide structure 40, Figure 5 in [reference], the intersection point of the focused light is inside the light guide structure 40. Combining Figure 2 with Figure 3 is a lateral light guide system, Figure 4 and Figure 5 is a light guide system combining longitudinal and lateral directions. Therefore, Figures 2 - 5 substantially provides four different light guide system layouts, and the core of these four different layouts is achieved by using the first reflector 25, the second reflector 26, and the third reflector 27. This fully demonstrates that this embodiment not only solves the problem of yellowing and burning of the light guide structure 40 through spatial conversion, but also makes the arrangement of the light source position more flexible, and the shape of the light guide system can also be more diverse and flexible.

[0079] It should be noted that on the one hand, in this embodiment, the focus point of the focused light becomes controllable, which will make the finally obtained light guide system more flexible and variable, and at the same time further effectively prevent the light guide structure 40 from turning yellow and burning due to heat loss of the light source. On the other hand, in this embodiment, the light in the second direction is substantially focused to the same point, avoiding the defocusing situation. For the entire light guide system, in this embodiment, the light rays at different positions are focused to the same point, enabling the light guide system to support multiple sets of light rays with different light colors, thereby realizing the reuse of vehicle lights.

[0080] In one embodiment, the intersection point of the focused light of the lens structure 30 is located on the central axis of the light guide structure 40.

[0081] In this embodiment, the lens structure 30 leads the intersection point of the focused light to be perpendicular to the central axis of the light guide structure 40. For example, as Figure 4 shown, the intersection point of the focused light is on the central axis outside the light guide structure 40, while Figure 5 in [reference], the intersection point of the focused light is on the central axis inside the light guide structure 40.

[0082] It should be noted that, on the one hand, due to the flexible shape of the light guide structure 40, the light guide structure 40 in Figures 2 - 5 is only for illustration and not the true shape of the light guide structure 40. Therefore, in this embodiment, the intersection point of the focused light is stably focused on the central axis of the light guide structure 40, further making the overall light guide system more stable and diverse. On the other hand, since different second-direction lights are converged onto the central axis, this effectively avoids the occurrence of defocusing.

[0083] Each device in the above embodiment of the present utility model solves three problems existing in the system using the light guide structure 40 in the prior art: First, the present utility model eliminates the limitation on the position of the light source by the light guide structure 40. The position of the light source can be more flexible, which meets the requirement that the light guide structure 40 needs to adapt to different shapes and also makes the optical system more flexible; Second, since the light source in the present utility model undergoes multiple spatial position conversions, the influence of the heat loss of the light source on the light guide structure 40 is avoided, thereby reducing the yellowing and burning of the light guide structure 40; Third, since the present utility model supports multiple sets of light sources with different light colors, that is, multiple sets of light sources at different positions can also be focused on the same point, this not only avoids the occurrence of defocusing but also realizes the multiplexing of the functions of vehicle lights.

[0084] In one embodiment, a lamp group is provided, and the lamp group includes a plurality of light sources and the light guide system as described in the above embodiment.

[0085] In one embodiment, the lamp group further includes a PCB board 13, and one or more light-emitting sources are distributed on the PCB board 13; the PCB board 13 is located inside the light-condensing structure 10 of the light guide system.

[0086] It should be noted that there may be multiple first light-emitting sources 11 on the PCB (printed circuit board, full name Printed Circuit Board) board 13. In this embodiment, the first light-emitting source 11 is preferably an LED, but the type of the light source is not limited, and MiniLED, OLED, etc. are all compatible with this system. That is, there will be multiple LEDs on the PCB serving as the first light-emitting source 11 in this embodiment. Each first light-emitting source 11 can have its own light color. After the light rays emitted by these LEDs pass through the light-condensing structure 10, the refractive device 20, and the lens structure 30, the above light guide system guides them into the light guide structure 40. There is no need to limit the position of the PCB board 13 or the first light-emitting source 11 throughout this entire process, which supports multiple sets of different light colors and can multiplex the light rays of vehicle lights. The achieved effect not only effectively avoids the occurrence of defocusing, but also since the light-condensing structure 10, the refractive device 20, and the lens structure 30 move the first light-emitting source 11 away from the light guide structure 40, the influence of the heat loss of the first light-emitting source 11 on the light guide structure 40 is effectively reduced, preventing the yellowing and burning of the light guide structure 40.

[0087] In one embodiment, a vehicle is provided, which includes the lamp set in the above embodiment.
