[0036] The following will clearly and completely describe the technical solutions in the embodiments of the present application in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present application.

[0037] As described in the background art, with the continuous development of the economy and the continuous improvement of people's living standards, consumers' demand for automobiles is becoming increasingly strong. As one of the core components of automobiles, the market demand for vehicle lights is also increasing continuously with the rapid development of the automobile market. Traditional vehicle light designs have some deficiencies in meeting the requirements of modern automobile industry. Therefore, it is necessary to improve the performance and user experience of vehicle lights through technological innovation. For example, reflective lighting vehicle lights are active in the current lighting market due to their advantages such as low cost and high efficiency. However, with the growth of the demand in the automobile market and related technologies, the performance of existing reflective lighting vehicle lights still needs to be further improved.

[0038] Based on this, the embodiments of the present application provide a reflector, a lighting device and a vehicle, which effectively solve the technical problems existing in the prior art, improve the reflection effect of the reflector, improve the glare problem caused by disordered stray light, and improve the performance of the lighting device.

[0039] To achieve the above object, the technical solutions provided by the embodiments of the present application are as follows, specifically in combination with Figures 1 to 10 to describe in detail the technical solutions provided by the embodiments of the present application.

[0040] Refer to Figure 1 As shown, it is a schematic structural diagram of a reflector provided by an embodiment of the present application. Among them, the reflector includes:

[0041] A plurality of reflecting surfaces 101, the reflecting surfaces 101 are curved surfaces, and at least some of the reflecting surfaces 101 have a common focus Q with the same focus. It should be noted that Figure 1 The shown common focus Q only indicates that at least some of the reflecting surfaces 101 have the same focus, and does not limit that the position where it is located is Figure 1 the position shown. For this, it needs to be analyzed according to the specific shape of the reflecting surface 101 in actual application.

[0042] At least two adjacent reflecting surfaces 101 are connected by a stepped surface 102. Among them, at the stepped surface 102, the connection boundaries of the two adjacent reflecting surfaces 101 and the stepped surface 102 have a height difference H. As Figure 1 shown by the reflecting surface 101a and the reflecting surface 101b, the reflecting surface 101a and the reflecting surface 101b are connected by the stepped surface 101, and there is a height difference H between the connection boundary of the reflecting surface 101a and the stepped surface 102 and the connection boundary of the reflecting surface 101b and the stepped surface 102. When the light-emitting light source is set at the common focus Q, the emitted light rays of the light-emitting light source cannot irradiate on the stepped surface 102.

[0043] It can be understood that in the technical solution provided by the embodiments of the present application, at least two adjacent reflecting mirrors 101 are connected by a stepped surface 102. When the reflecting mirror is applied to a lighting device, a light-emitting light source is arranged at the common focus Q of the reflecting mirror, so that the emitted light of the light-emitting light source cannot irradiate the stepped surface 102. Therefore, the generation of disordered stray light due to reflection at the stepped surface 102 is avoided, the glare problem caused by the disordered stray light is improved, the reflection effect of the reflecting mirror is improved, and the performance of the lighting device is improved. In addition, when the reflecting mirror provided by the embodiments of the present application is applied to a lighting device of the headlight type, it can not only prevent glare and ensure high safety of road lighting; moreover, by setting the shape of the reflecting mirror surface 101 as a curved surface, it can also meet the near-light three-zone lighting requirements, without the need to separately open a mold to manufacture the three-zone reflecting surface, thereby reducing the cost of the reflecting mirror and improving the aesthetic appearance of the lighting device.

[0044] Preferably, the foci of all the reflecting mirror surfaces 101 provided by the embodiments of the present application are the same common focus Q, and any two adjacent reflecting mirror surfaces 101 are connected by a stepped surface 102, whereby the glare problem caused by disordered stray light can be further improved, and further, the reflection effect of the reflecting mirror and the performance of the lighting device can be improved.

[0045] In an embodiment of the present application, all the reflecting mirror surfaces 101 provided by the embodiments of the present application may be arranged irregularly; or, all the reflecting mirror surfaces provided by the embodiments of the present application are arranged regularly, such as in an array arrangement. Refer to Figure 2 As shown, it is a schematic structural diagram of another reflecting mirror provided by the embodiments of the present application. Among them, the multiple reflecting mirror surfaces 101 provided by the embodiments of the present application include at least two rows of reflecting mirror surfaces 101 arranged along the first direction Y, and all the reflecting mirror surfaces 101 in any one row are arranged in sequence along the second direction X; the first direction Y and the second direction X intersect. Optionally, the first direction Y and the second direction X provided by the embodiments of the present application may intersect perpendicularly, wherein all the reflecting mirror surfaces 101 are arranged in a multi-row * multi-column array arrangement.

[0046] Two adjacent reflecting mirror surfaces 101 are connected by a stepped surface 102, and there is a height difference between the connection boundaries where the two adjacent reflecting mirror surfaces 101 are connected to the stepped surface 102. Specifically, in combination with Figure 3 and Figure 4 shown, Figure 3 is Figure 2 the sectional view along the AA' direction in Figure 4 is Figure 3 the partial enlarged view at the stepped surface inFigure 5 and Figure 6 as shown Figure 5 is Figure 2 a sectional view along the BB' direction in Figure 6 is Figure 5 a partially enlarged view of the stepped surface at the interruption. In the second direction X, two adjacent reflecting mirrors 101 are connected by a stepped surface 102, and there is a height difference between the connecting boundaries where the two adjacent reflecting mirrors 101 are connected to the stepped surface 102.

[0047] Continuing to combine Figure 4 and Figure 6 as shown, in the embodiment of the present application, the inclination degree of the stepped surface 102 can be optimized, that is, the overlapping area of two adjacent reflecting mirrors 101 at the stepped surface 102 is optimized, and at the same time, the height difference between two adjacent reflecting mirrors 101 is optimized to ensure that the stepped surface 102 cannot be irradiated by the emitted light of the light-emitting light source, thereby avoiding the generation of disordered stray light when the emitted light irradiates the stepped surface 102 and improving the glare problem caused by unnecessary stray light. It should be noted that the inclination degree and size of the stepped surface 102 in the embodiment of the present application are not specifically limited, and specific design needs to be carried out according to actual applications, as long as it satisfies that the emitted light of the light-emitting light source cannot irradiate the stepped surface 102.

[0048] In an embodiment of the present application, the shape of the reflecting mirror 101 provided in the embodiment of the present application can be a paraboloid. Among them, the reflecting mirror is composed of a plurality of reflecting mirrors 101 with a parabolic profile, and preferably all the reflecting mirrors 101 with a parabolic profile have the same common focus Q. In the embodiment of the present application, two adjacent reflecting mirrors 101 with a parabolic profile are connected by a stepped surface 102 to ensure that the stepped surface 102 cannot be irradiated by the emitted light of the light-emitting light source, thereby avoiding the generation of disordered stray light when the emitted light irradiates the stepped surface 102 and improving the glare problem caused by unnecessary stray light. In addition, when the reflecting mirror provided in the embodiment of the present application is applied to a lighting device of the headlight type, it can not only prevent glare and ensure high safety of road lighting; moreover, by setting the shape of the reflecting mirror 101 as a paraboloid, it can also meet the near-light three-zone lighting requirements, without the need to separately open a mold to manufacture the three-zone reflecting surface, thereby reducing the cost of the reflecting mirror and improving the aesthetic appearance of the lighting device.

[0049] In the structure of the reflecting mirror, the reflecting mirror can be composed of a substrate and a reflecting layer on the substrate, and the reflecting mirror surface 101 can be the surface of the reflecting layer. Specifically combined with Figure 7 as shown, which is a schematic structural diagram of another reflecting mirror provided in the embodiment of the present application. Among them, the reflecting mirror provided in the embodiment of the present application includes:

[0050] Base 10, the base 10 includes a bearing portion 11 corresponding to the reflecting mirror surface 101.

[0051] And, a reflective layer 20 located on the surface of the base 10. Wherein, at the bearing portion 11, the surface of the reflective layer 20 facing away from the base is the reflecting mirror surface 101. It should be noted that the shape of the bearing portion 11 facing the reflective layer 20 in the embodiment of the present application can be a curved surface. Thus, when forming the reflective layer 20 on the surface of the bearing portion 11, a reflecting mirror surface 101 with a curved surface shape can be formed. And, the shape of the side of the base 10 facing away from the reflective layer 20 can be a curved surface or other shapes. Or, the shape of the bearing portion 11 facing the reflective layer 20 in the embodiment of the present application can be a plane, and a reflecting mirror surface 101 with a curved surface is formed when manufacturing the reflective layer 20. The present application does not make specific restrictions on this, and specific design needs to be carried out according to actual applications.

[0052] Continue to refer to Figure 7 As shown, the base 10 provided in the embodiment of the present application further includes a connecting portion 12 corresponding to the stepped surface 102. Wherein, the reflective layer 20 can cover the surface of the connecting portion 12, and the stepped surface 102 is the surface of the reflective layer 20 at the connecting portion 12. Or refer to Figure 8 As shown, it is a schematic structural diagram of another reflecting mirror provided in the embodiment of the present application. Wherein, the reflective layer 20 provided in the embodiment of the present application can only cover the surface of the bearing portion 11, rather than covering the surface of the connecting portion 12. Therefore, the stepped surface 102 is the surface of the connecting portion 12. The present application does not make specific restrictions on this, and specific analysis needs to be carried out according to actual applications.

[0053] In an embodiment of the present application, the reflective layer 20 provided in the embodiment of the present application includes a metal coating. Wherein, at the bearing portion 11, the surface of the metal coating facing away from the base 10 is the reflecting mirror surface 101. The metal coating provided in the embodiment of the present application is used to reflect and redistribute the emitted light of the light-emitting light source. Therefore, a metal material with a relatively high reflectivity is preferably selected. Optionally, the metal coating can be an aluminized film; or, in other embodiments of the present application, the metal coating provided in the embodiment of the present application can also select other metal materials with a high reflectivity.

[0054] Refer to Figure 9As shown in the figure, this is another structural schematic diagram of a reflector provided by an embodiment of the present application. Among them, on the basis that the reflective layer 20 provided by the embodiment of the present application includes a metal coating 21, the reflective layer 20 further includes a varnish layer 22 sprayed on the surface of the bearing portion 11. Among them, the metal coating 21 is located on the side of the varnish layer 22 away from the substrate 10. The material of the substrate 10 provided by the embodiment of the present application can be a resin-based material. Furthermore, spraying the varnish layer 22 between the metal coating 21 and the bearing portion 11 can not only improve the bonding strength between the metal coating 21 and the bearing portion 11, but also due to the surface tension of the paint and the principle of fluidics, the varnish layer 22 will form a fixed fluid shape (bevel shape) and angle a on the surface at the edge of the bearing portion 11. Furthermore, when forming the metal coating 21 on the varnish layer 22, the same angle will also be formed at the edge. This angle can reflect the emitted light rays of the light-emitting light source to the near-light three-zone area; that is, the normal exit light ray angle passing through the reflecting mirror surface 101 is below the cut-off line of the low beam, while the exit light ray angle of the part of the reflecting mirror surface 101 corresponding to the edge bevel of the varnish layer 22 is above the cut-off line of the low beam, thus better meeting the lighting requirements of the near-light three-zone area, eliminating the need to separately mold a three-zone reflecting surface, thereby reducing the cost of the reflector and improving the aesthetic appearance of the lighting device. Optionally, the inner angle a of the edge of the part of the varnish layer 22 corresponding to the bearing portion 11 ranges from 2 to 6 degrees.

[0055] Furthermore, the reflector provided by the embodiment of the present application further includes a fixing portion for fixing with other structures, such as screw fixing, welding fixing, etc., and the present application does not make specific limitations on this.

[0056] Based on the same inventive concept, the embodiment of the present application also provides a lighting device. Refer to Figure 10 As shown in the figure, this is a structural schematic diagram of a lighting device provided by the embodiment of the present application. Among them, the lighting device provided by the embodiment of the present application includes:

[0057] The reflector 100 provided by any one of the above embodiments; the reflector includes: a plurality of reflecting mirror surfaces 101, the reflecting mirror surfaces 101 are curved surfaces, and at least some of the reflecting mirror surfaces 101 have a common focus Q with the same focus. At least two adjacent reflecting mirror surfaces 101 are connected by a stepped surface 102; at the stepped surface 102, the connection boundary line between the two adjacent reflecting mirror surfaces 101 and the stepped surface 102 has a height difference H.

[0058] And, a light-emitting light source 200, the light-emitting light source 200 is arranged at the common focus Q.

[0059] It can be understood that the light-emitting light source 200 provided in the embodiment of the present application is used to provide emitted light. After the emitted light irradiates on the reflector 100, it is reflected by the reflector 100 and redistributed into outgoing light. In the technical solution provided by the embodiment of the present application, at least two adjacent reflecting surfaces 101 are connected by a stepped surface 102. The light-emitting light source 200 is disposed at the common focus Q of the reflector 100, so that the emitted light of the light-emitting light source 200 cannot irradiate on the stepped surface 102. Therefore, the generation of disordered stray light due to reflection at the stepped surface 102 is avoided, the glare problem caused by the disordered stray light is improved, the reflection effect of the reflector 100 is improved, and the performance of the lighting device is improved. In addition, when the reflector 100 provided by the embodiment of the present application is applied to a lighting device of the headlight type, it can not only prevent glare and ensure high safety of road lighting; moreover, by setting the shape of the reflecting surface 101 as a curved surface, it can also meet the requirements of near-light three-zone lighting, without the need to separately open a mold to manufacture the three-zone reflecting surface, thereby reducing the cost of the reflector 100 and improving the appearance beauty of the lighting device.

[0060] Preferably, the foci of all the reflecting surfaces 101 provided by the embodiment of the present application are the same common focus Q, and any two adjacent reflecting surfaces 101 are connected by a stepped surface 102, thereby being able to further improve the glare problem caused by disordered stray light, and further improving the reflection effect of the reflector 100 and the performance of the lighting device.

[0061] In an embodiment of the present application, all the reflecting surfaces 101 provided by the embodiment of the present application may be arranged irregularly; or, all the reflecting surfaces provided by the embodiment of the present application are arranged regularly, such as in an array arrangement. Continuing to refer to Figure 2 As shown, the multiple reflecting surfaces 101 provided by the embodiment of the present application include at least two rows of reflecting surfaces 101 arranged along the first direction Y, and all the reflecting surfaces 101 in any one row are arranged in sequence along the second direction X; the first direction Y and the second direction X intersect. Optionally, the first direction Y and the second direction X provided by the embodiment of the present application may intersect perpendicularly, wherein all the reflecting surfaces 101 are arranged in a multi-row * multi-column array arrangement. Any two adjacent reflecting surfaces 101 are connected by a stepped surface 102, and there is a height difference between the connection boundaries where the two adjacent reflecting surfaces 101 are connected to the stepped surface 102. Specifically, in combination with Figure 3 and Figure 4 As shown, in the first direction Y, any two adjacent reflecting surfaces 101 are connected by a stepped surface 102, and there is a height difference between the connection boundaries where the two adjacent reflecting surfaces 101 are connected to the stepped surface 102. And in combination with Figure 5 and Figure 6As shown, two adjacent reflecting mirrors 101 are connected by a stepped surface 102, and there is a height difference between the connection boundaries where the two adjacent reflecting mirrors 101 are connected to the stepped surface 102.

[0062] Continuing to combine Figure 4 and Figure 6 As shown, in the embodiment of the present application, the inclination degree of the stepped surface 102 can be optimized, that is, the overlapping area of two adjacent reflecting mirrors 101 at the stepped surface 102 is optimized. At the same time, the height difference between two adjacent reflecting mirrors 101 is optimized to ensure that the stepped surface 102 cannot be irradiated by the emitted light of the light-emitting light source, thereby avoiding the generation of disordered stray light caused by the emitted light irradiating the stepped surface 102 and improving the glare problem caused by unnecessary stray light. It should be noted that the inclination degree and size of the stepped surface 102 in the embodiment of the present application are not specifically limited, and specific designs need to be made according to actual applications, as long as at least the emitted light of the light-emitting light source cannot irradiate the stepped surface 102.

[0063] In an embodiment of the present application, the shape of the reflecting mirror 101 provided by the embodiment of the present application can be a paraboloid. Among them, the reflecting mirror is composed of a plurality of reflecting mirrors 101 with a parabolic profile, and preferably all the reflecting mirrors 101 with a parabolic profile have the same common focus Q. In the embodiment of the present application, two adjacent reflecting mirrors 101 with a parabolic profile are connected by a stepped surface 102 to ensure that the stepped surface 102 cannot be irradiated by the emitted light of the light-emitting light source, thereby avoiding the generation of disordered stray light caused by the emitted light irradiating the stepped surface 102 and improving the glare problem caused by unnecessary stray light. In addition, when the reflecting mirror provided by the embodiment of the present application is applied to a lighting device of the headlight type, it can not only prevent glare and ensure high safety of road lighting; moreover, by setting the shape of the reflecting mirror 101 as a paraboloid, it can also meet the near-light three-zone lighting requirements, without the need to separately open a mold to make a three-zone reflecting surface, thereby reducing the cost of the reflecting mirror and improving the aesthetic appearance of the lighting device.

[0064] In the structure of the reflecting mirror 100, the reflecting mirror 100 can be composed of a substrate and a reflecting layer on the substrate, and the reflecting mirror surface 101 can be the surface of the reflecting layer. Specifically combining Figure 7 As shown, the reflecting mirror provided by the embodiment of the present application includes:

[0065] A substrate 10, the substrate 10 includes a bearing part 11 corresponding to the reflecting mirror surface 101.

[0066] And a reflective layer 20 located on the surface of the substrate 10. At the bearing part 11, the surface of the reflective layer 20 facing away from the substrate is the reflective mirror surface 101. It should be noted that the shape of the side of the bearing part 11 facing the reflective layer 20 in the embodiment of the present application can be a curved surface. Thus, when forming the reflective layer 20 on the surface of the bearing part 11, a reflective mirror surface 101 with a curved surface shape can be formed. And the shape of the side of the substrate 10 facing away from the reflective layer 20 can be a curved surface or other shapes. Or, the shape of the side of the bearing part 11 facing the reflective layer 20 in the embodiment of the present application can be a plane, and a reflective mirror surface 101 with a curved surface is formed when manufacturing the reflective layer 20. The present application does not make specific restrictions on this and specific designs need to be carried out according to actual applications.

[0067] Continue to refer to Figure 7 As shown, the substrate 10 provided in the embodiment of the present application further includes a connecting part 12 corresponding to the step surface 102. The reflective layer 20 can cover the surface of the connecting part 12, and the step surface 102 is the surface of the reflective layer 20 at the connecting part 12. Or refer to Figure 8 As shown, it is a schematic structural diagram of another reflective mirror provided in the embodiment of the present application. The reflective layer 20 provided in the embodiment of the present application can only cover the surface of the bearing part 11, rather than covering the surface of the connecting part 12. Therefore, the step surface 102 is the surface of the connecting part 12. The present application does not make specific restrictions on this and specific analyses need to be carried out according to actual applications.

[0068] In an embodiment of the present application, the reflective layer 20 provided in the embodiment of the present application includes a metal coating. At the bearing part 11, the surface of the metal coating facing away from the substrate 10 is the reflective mirror surface 101. The metal coating provided in the embodiment of the present application is used to reflect and redistribute the emitted light of the light-emitting light source. Therefore, a metal material with a relatively high reflectivity is preferably selected. Optionally, the metal coating can be an aluminized film; or, in other embodiments of the present application, the metal coating provided in the embodiment of the present application can also select other metal materials with high reflectivity.

[0069] Continue to combine with Figure 9As shown in the figure, on the basis that the reflective layer 20 provided in the embodiment of the present application includes a metal coating 21, the reflective layer 20 further includes a varnish layer 22 sprayed on the surface of the bearing portion 11, wherein the metal coating 21 is located on the side of the varnish layer 22 away from the substrate 10. The material of the substrate 10 provided in the embodiment of the present application can be a resin-based material. Furthermore, spraying the varnish layer 22 between the metal coating 21 and the bearing portion 11 can not only improve the bonding strength between the metal coating 21 and the bearing portion 11, but also, due to the surface tension of the paint and the principle of fluidics, the varnish layer 22 will form a fixed fluid shape (inclined plane shape) and an angle a on the surface at the edge of the bearing portion 11. Then, when the metal coating 21 is formed on the varnish layer 22, the same angle will also be formed at the edge. This angle can reflect the emitted light of the light-emitting source to the low beam three-zone area; that is, the angle of the emitted light passing through the normal reflecting mirror 101 is below the low beam cut-off line, while the angle of the emitted light passing through the part of the reflecting mirror 101 corresponding to the inclined plane at the edge of the varnish layer 22 is above the low beam cut-off line, thus better meeting the low beam three-zone lighting requirements, eliminating the need to separately mold a three-zone reflecting surface, reducing the cost of the reflecting mirror, and improving the aesthetic appearance of the lighting device. Optionally, the inner angle a of the edge of the part of the varnish layer 22 corresponding to the bearing portion 11 ranges from 2 to 6 degrees.

[0070] Based on the same inventive concept, the embodiment of the present application further provides a vehicle, wherein the vehicle provided in the embodiment of the present application includes the lighting device provided in any one of the above embodiments.

[0071] It should be noted that the vehicle provided in the embodiment of the present application can be a vehicle or the like, and the lighting device can be a reflective lighting vehicle lamp. The present application does not make specific limitations in this regard.

[0073] As can be seen from the above, in the technical solution provided by the embodiment of the present application, at least two adjacent reflecting mirrors are connected by a stepped surface. When the reflecting mirror is applied to a lighting device, the light-emitting source is arranged at the common focus of the reflecting mirror, so that the emitted light of the light-emitting source cannot irradiate the stepped surface. Therefore, the generation of disordered stray light by reflection at the stepped surface is avoided, the problem of glare caused by disordered stray light is improved, the reflection effect of the reflecting mirror is improved, and the performance of the lighting device is improved.
