Abstract
Description
A vehicle lighting assembly, a vehicle light, and a vehicle Technical Field
[0001] This application belongs to the field of automotive lighting technology, and in particular relates to a vehicle lamp assembly, a vehicle lamp, and a vehicle. Background Technology
[0002] In recent years, with the development trend of automotive intelligence and the demand for car headlight design, the automotive headlight field has made many corresponding adjustments and progresses. For example, more and more car headlights now use lamp components that integrate multiple headlight functions into one unit, thereby achieving integration of functions such as low beam, high beam, or signal light.
[0003] Taking a lamp assembly with integrated high and low beam functions as an example, in the existing automotive lamp solutions where the low beam and high beam share the same lens, the low beam system and the high beam system often need to be arranged vertically. This means that the light sources for the high beam and low beam cannot share a single circuit board, resulting in a complex system with high costs. Moreover, with the low beam and high beam systems arranged vertically, the lenses need to be partitioned. After partitioning, the lenses are not fully lit when the high beam or low beam functions are turned on, resulting in inconsistent appearance of the lenses when the lamp is lit. To improve the appearance, additional costs are required.
[0004] Application content
[0005] The purpose of this application is to provide a vehicle lighting assembly, a vehicle lighting system, and a vehicle to solve the problem in the prior art where the low beam system and high beam system are arranged vertically, resulting in complex parts and inconsistent lighting appearance.
[0006] To solve the above problems, the technical solution of this application is as follows:
[0007] This application discloses a vehicle lighting assembly, which includes at least a first optical unit, a second optical unit, and a projection unit.
[0008] The first optical unit includes a first light source and a first primary optical element. The first primary optical element is a transparent component and has a first incident surface, a first reflecting surface, and a first exiting surface. The light beam emitted from the first light source enters the first primary optical element through the first incident surface, is converged and reflected by the first reflecting surface, and then exits through the first exiting surface to form a first light beam that propagates along the optical axis. The first light beam then achieves a first light function after passing through the projection unit.
[0009] The second optical unit includes a second light source and a second primary optical element. The second light source and the first light source are disposed on the same light source mounting surface and are arranged along the optical axis. The second primary optical element has a second reflecting surface, and the first primary optical element also has a third incident surface. The third incident surface is correspondingly disposed to the second reflecting surface, so that the light beam emitted from the second light source is converged and reflected by the second reflecting surface, enters the first primary optical element through the third incident surface, and is emitted from the first exit surface to form a second light beam that is transmitted along the optical axis. The second light beam realizes the second light function after passing through the projection unit.

[0014] In the vehicle lamp assembly of this application, optionally, the second primary optical element is a transparent part. The second primary optical element also has a second incident surface and a second exit surface.

After exiting through the third incident surface, it enters the first primary optical element and exits through the first exit surface to form a second light beam that propagates along the optical axis. The second light beam realizes the second light function after passing through the projection unit.
[0015] In the vehicle headlight assembly of this application, optionally, the first primary optical element further includes a third reflective surface. The light beam emitted from the second light source is converged and reflected by the second primary optical element and then enters the first primary optical element through the third incident surface. Part of the light beam is reflected by the third reflective surface and emitted from the first exiting surface to form a part of the second light beam that is transmitted along the optical axis. The second light beam realizes the second light function after passing through the projection unit.
[0016] Optionally, in the vehicle lighting assembly of this application, the first light source is a low beam light source.
[0017] In the vehicle headlight assembly of this application, optionally, the first light source is a low beam light source; a cutoff line structure is provided at the boundary of the first reflective surface near the low beam light source, and the beam emitted from the low beam light source is cut off by the cutoff line structure and converged and reflected by the first reflective surface before being emitted from the first emission surface to form a first beam that propagates along the optical axis direction, and the first beam achieves the low beam function after passing through the projection unit.
[0018] In the vehicle headlight assembly of this application, optionally, the first light source is a low beam light source; the second reflective surface is an ellipsoid or a near-ellipsoidal surface, the second light source is disposed at the first focal point of the second reflective surface, and the second focal point of the second reflective surface is located on or within 5 mm of the third reflective surface.
[0019] In the vehicle lighting assembly of this application, optionally, the second light source is a low beam light source.
[0020] In the vehicle headlight assembly of this application, optionally, the second light source is a low beam light source; a cutoff line structure is provided at the boundary of the second reflective surface near the low beam light source, the beam emitted from the low beam light source is cut off by the cutoff line structure and converged and reflected by the second reflective surface, and then enters the first primary optical element through the third incident surface and is emitted from the first exiting surface to form a second beam that propagates along the optical axis direction, and the second beam realizes the low beam light function after passing through the projection unit.

The beam emitted from the second light source passes through a second primary optical element and a first primary optical element to form a second beam, which then performs a second light function through a projection unit. The projection unit does not need to be partitioned for the first and second light functions, thus eliminating any issues with the appearance of the lighting. Attached Figure Description

Detailed Implementation
[0041] To more clearly illustrate the technical solutions in the embodiments of this application or the prior art, the specific implementation methods of this application will be described below with reference to the accompanying drawings. Obviously, the accompanying drawings described below are only some embodiments of this application. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without creative effort.
[0042] To keep the drawings concise, each drawing only schematically shows the parts relevant to this application, and they do not represent the actual structure of the product. Furthermore, for ease of understanding, in some drawings, only one of the components with the same structure or function is schematically shown, or only one is labeled. In this document, "one" not only means "only one," but can also mean "more than one."
[0043] The first aspect of this application provides a vehicle lighting assembly. Referring to Figures 1 to 18, as a basic embodiment of this application, the vehicle lighting assembly includes at least a first optical unit, a second optical unit, and a projection unit.
[0044] The first optical unit includes a first light source 1 and a first primary optical element 3. The first primary optical element 3 is a transparent component. The first primary optical element 3 has a first incident surface 31, a first reflecting surface 33, and a first exit surface 35. The light beam emitted from the first light source 1 enters the first primary optical element 3 through the first incident surface 31, is converged and reflected by the first reflecting surface 33, and is then emitted from the first exit surface 35 to form a first light beam that propagates along the optical axis. The first light beam then performs the first optical function after passing through the projection unit.
[0045] The second optical unit includes a second light source 2 and a second primary optical element 4. The second light source 2 and the first light source 1 are disposed on the same light source mounting surface and are arranged along the optical axis. The second primary optical element 4 has a second reflecting surface 42, and the first primary optical element 3 also has a third incident surface 32. The third incident surface 32 is correspondingly disposed to the second reflecting surface 42 so that the light beam emitted from the second light source 2 is converged and reflected by the second reflecting surface 42, enters the first primary optical element 3 through the third incident surface 32, and is emitted from the first exit surface 35 to form a second light beam that is transmitted along the optical axis. The second light beam realizes the second light function after passing through the projection unit.
[0046] Based on the above basic embodiments, the vehicle lamp assembly of this application uses a first light source 1 and a second light source 2 mounted on the same light source mounting surface, and the first light source 1 and the second light source 2 are arranged along the optical axis direction. Therefore, they can share a single circuit board, thereby simplifying the components of the entire vehicle lamp system and reducing the cost of the vehicle lamp system. Moreover, the beam emitted from the first light source 1 passes through the first primary optical element 3 to form a first beam, and the first beam realizes the first light function through the projection unit. The beam emitted from the second light source 2 passes through the second primary optical element 4 and the first primary optical element 3 to form a second beam, and the second beam realizes the second light function through the projection unit. The projection unit does not need to be partitioned for the first light function and the second light function, so there are no issues with the appearance of the lamp when it is lit.
[0047] It should be understood that, in addition to being a high beam light source and a low beam light source, the first light source 1 and the second light source 2 of the vehicle lamp assembly of this application can be any two of the following: a main low beam light source and an auxiliary low beam light source, a main high beam light source and an auxiliary high beam light source, or a signal light source and a projection light source. Here, a signal light source refers to a light source used in vehicle headlights and taillights to indicate signals, such as a light source used in daytime running lights, a light source used in turn signals, or a light source used in brake lights; a projection light source refers to a light source installed on the vehicle lamps or body that can realize pattern projection or information interaction, such as a light source used in Surrounding Interactive Dynamic Projection (SIDP), a light source used in Interactive Signal Display (ISD), or a light source used in Digital Light Processing (DLP).
[0048] In addition, the vehicle light assembly of this application can realize two or more light functions. For example, a third light source can be added. The third light source, the first light source 1, and the second light source 2 are arranged along the optical axis. By setting the corresponding optical device for the third light source, the beam emitted by the third light source can be transmitted along the optical axis and realize the third light function.
[0049] The specific structure of the vehicle light assembly in the basic embodiment of this application will be further described below.
[0050] The second primary optical element 4, the first primary optical element 3, and the projection unit are arranged from back to front along the optical axis.
[0051] The first primary optical element 3 also includes a third reflecting surface 34. The light beam emitted from the second light source 2 is converged and reflected by the second primary optical element 4 and then enters the first primary optical element 3 through the third incident surface 32. Part of the light beam is reflected by the third reflecting surface 34 and emitted by the first exiting surface 35 to form a part of the second light beam that is transmitted along the optical axis. The second light beam realizes the second light function after passing through the projection unit.
[0052] Specifically, the first primary optical element 3 has a first reflecting surface 33 and a third reflecting surface 34 formed at the boundary with the external gas. The first reflecting surface 33 and the third reflecting surface 34 are located in different regions inside the first primary optical element 3. Preferably, on the outer surface of the first primary optical element 3, the region corresponding to the first reflecting surface 33 is the third incident surface 32, and the region corresponding to the third reflecting surface 34 is the first incident surface 31.
[0053] The first exit surface 35 of the first primary optical element 3 is arranged facing forward in the direction of the optical axis (that is, in the direction of the lens 5), and the third incident surface 32 is arranged facing backward in the direction of the optical axis (that is, in the direction of the second primary optical element 4); the first light source 1 is arranged outside the first incident surface 31 of the first primary optical element 3.
[0054] The second reflecting surface 42 on the second primary optical element 4 is positioned facing forward in the direction of the optical axis (that is, facing the direction of the first primary optical element 3), corresponding to the third incident surface 32 on the first primary optical element 3. This allows the light beam emitted from the second light source 2 to converge and be reflected by the second reflecting surface 42, and then face forward in the direction of the optical axis, thereby entering the first primary optical element 3 through the third incident surface 32 on the first primary optical element 3 located in front.
[0055] The projection unit can be a lens 5. The light-emitting surface of the lens 5 is preferably flat, which makes the lens 5 more aesthetically pleasing.
[0056] In this embodiment, preferably, the light-incident surface of the lens 5 is a cylindrical surface formed by stretching a curve laterally, and the first exit surface 35 of the first primary optical element 3 is a cylindrical surface formed by stretching a curve longitudinally. That is, the light-incident surface of the lens 5 is a unidirectional collimating surface, converging light longitudinally; the first exit surface 35 of the first primary optical element 3 is a unidirectional collimating surface, collimating light laterally. Compared to a scheme where the light-incident surface of the lens 5 is configured to converge light laterally and the first exit surface 35 of the first primary optical element 3 is configured to collimate light vertically, the scheme in this embodiment is beneficial for the overall thinning of the lens 5 and makes the appearance of the lens 5 more aesthetically pleasing.
[0057] It should be noted that in the specific application of the vehicle headlight assembly as an integrated high and low beam module in this application, one of the first optical unit and the second optical unit is a low beam optical unit and the other is a high beam optical unit, that is, one of the first light source 1 and the second light source 2 is a low beam light source and the other is a high beam light source. The following description is based on different specific embodiments, wherein, for ease of understanding, the projection unit is a lens.
[0058] Example 1
[0059] Referring to Figures 1 to 10, in this embodiment, the first light source 1 is a low-beam light source, and the second light source 2 is a high-beam light source. A cutoff structure 36 is provided at the boundary of the first reflective surface 33 near the low-beam light source 1. The beam emitted from the low-beam light source is cut off by the cutoff structure 36 and then converged and reflected by the first reflective surface 33 before being emitted from the first emission surface 35 to form a first beam that propagates along the optical axis. The first beam then passes through the lens 5 to achieve the low-beam function.
[0060] The second primary optical element 4 can be a reflector.
[0061] Furthermore, the second reflecting surface 42 on the second primary optical element 4 can be an ellipsoid or a near-ellipsoidal surface. The second light source 2 is positioned at the first focal point of the second reflecting surface 42, and the second focal point of the second reflecting surface 42 is located on or within 5 mm of the third reflecting surface 34. This allows the headlight assembly to achieve clearer high-beam imaging and brighter high-beam illumination when performing high-beam functionality. It should be noted that a near-ellipsoidal reflecting surface refers to a surface whose light-converging effect and appearance are similar to or close to that of an ellipsoidal reflecting surface.
[0062] The low beam path of the headlight assembly in this embodiment is shown in Figures 5 and 8. The light beam emitted from the low beam source (i.e., the first light source 1) enters the first primary optical element 3 through the first incident surface 31. Within the first primary optical element 3, the light is converged and reflected by the first reflecting surface 33 and then emitted from the first exit surface 35 to form a low beam (i.e., the first beam). The low beam then passes through the lens 5 to achieve the low beam function (i.e., the first light function). By adjusting the curvature of the first reflecting surface 33 in the first primary optical element 3, the light emitted from the first light source 1 undergoes total internal reflection on the first reflecting surface 33 as much as possible.
[0063] The high beam optical path of the vehicle headlight assembly in this embodiment is shown in Figures 9 and 10. The light beam emitted from the high beam source (i.e., the second light source 2) is converged and reflected by the second reflecting surface 42, then enters the first primary optical element 3 through the third incident surface 32 and exits from the first exit surface 35 to form a high beam beam (i.e., the second beam) that propagates along the optical axis. A large portion of the light is reflected by the third reflecting surface 34 within the first primary optical element 3. The high beam beam then passes through the lens 5 to achieve the high beam function (i.e., the second beam function). By adjusting the curved surfaces of the second reflecting surface 42 in the second primary optical element 4 and the third reflecting surface 34 in the first primary optical element 3, the light emitted from the second light source 2 undergoes total internal reflection on the third reflecting surface 34 as much as possible. In the high beam optical path, after the light emitted from the second light source 2 is reflected by the third reflecting surface 34 in the first primary optical element 3, the high beam image is flipped vertically. The dotted line in Figure 10 represents the position of the virtual high beam image.
[0064] In the vehicle lamp assembly provided in this embodiment, referring mainly to Figures 8 and 10, the energy concentration area of the second beam emitted from the second light source 2, when exiting from the first exit surface 35 of the first primary optical element 3, is more biased away from the third reflective surface 34 compared to the energy concentration area of the first beam emitted from the first light source 1 when exiting from the first exit surface 35 of the first primary optical element 3. That is, in this embodiment, the vertical bias of the energy concentration areas of the first and second beams after exiting through the lens 5 is already mainly adjusted when exiting from the first exit surface 35 of the first primary optical element 3. The lens 5 mainly focuses the energy to concentrate the beam and make the illumination brighter. Therefore, the lens 5 in this embodiment does not need to be partitioned, and there is no problem with the appearance of the lamp. Moreover, the first light source 1 and the second light source 2 can be set on the same light source mounting surface and arranged along the optical axis, so they can share a circuit board, thereby simplifying the components of the entire vehicle lamp system and reducing the cost of the vehicle lamp system.
[0065] Example 2
[0066] Referring to Figures 11 to 16, in this embodiment, the first light source 1 is a near light source and the second light source 2 is a far light source. The main difference between this embodiment and embodiment 1 is that the second primary optical element 4 in this embodiment is a transparent element.
[0067] The second primary optical element 4 also has a second incident surface 41 and a second exit surface 43. The light beam emitted from the second light source 2 enters the second primary optical element 4 through the second incident surface 41, is converged and reflected by the second reflecting surface 42, and then exits through the second exit surface 43. After exiting through the third incident surface 32, it enters the first primary optical element 3 and exits through the first exit surface 32 to form a second light beam that is transmitted along the optical axis. The second light beam then realizes the second light function after passing through the projection unit.
[0068] Specifically, the second primary optical element 4 has a second reflecting surface 42 formed at the boundary with the external gas. The second exiting surface 43 on the second primary optical element 4 can be curved or flat. The second exiting surface 43 on the second primary optical element 4 mainly plays the role of modulating the light spot energy. Therefore, the second exiting surface 43 on the second primary optical element 4 can be adjusted according to the actual requirements of the light spot energy.
[0069] Example 3
[0070] Referring to Figures 17 and 18, in this embodiment, the first light source 1 is a high-beam light source and the second light source 2 is a low-beam light source.
[0071] The structure of the vehicle lamp assembly in this embodiment can be obtained by flipping the first light source 1, the second light source 2, the first primary optical element 3, the second primary optical element 4, and the lens 5 together in Embodiment 1. In this way, the energy concentration area of the first beam (i.e., the high beam) after exiting through lens 5 will be higher than the energy concentration area of the second beam (i.e., the low beam) after exiting through lens 5. Of course, in specific designs, adjustments can be made to details (such as the curved surface details of the first reflective surface 33, the curved surface details of the second reflective surface 42, etc.) to achieve higher requirements for both low beam and high beam functions.
[0072] Since the second light source 2 is a near light source, a cutoff line structure 44 can be set at the boundary of the second reflective surface 42 near the near light source (the cutoff line structure 36 on the first primary optical element 3 in the original embodiment 1 is no longer set in this embodiment). The light beam emitted from the near light source is cut off by the cutoff line structure 44 and converged and reflected by the second reflective surface 42. It then enters the first primary optical element 3 through the third incident surface 32 and is emitted from the first exit surface 35 to form a near light beam (that is, the second beam) that is transmitted along the optical axis. The near light beam realizes the near light function after passing through the projection unit.
[0073] Furthermore, the first reflecting surface 33 can be an ellipsoid or a near-ellipsoidal surface, the first light source 1 is disposed at the first focal point of the first reflecting surface 33, and the second focal point of the first reflecting surface 33 is located on or within 5mm of the third reflecting surface 34. This allows the headlight assembly to achieve clearer high-beam imaging and brighter high-beam illumination when performing high-beam functionality.
[0074] As shown in Embodiments 1, 2, and 3 above, when the optical units that realize the low beam function and the high beam function are arranged front and rear respectively, the low beam light source and the high beam light source of this application are set on the same light source mounting surface, and the low beam light source and the high beam light source are arranged along the optical axis direction. Therefore, they can share a circuit board, thereby simplifying the parts of the entire vehicle lighting system and reducing the cost of the vehicle lighting system. Moreover, for example, when the low beam optical unit is arranged in front, the beam emitted by the low beam light source passes through the first primary optical element 3 and is emitted to form a first beam. The first beam realizes the low beam function through the projection unit. The beam emitted by the high beam light source passes through the second primary optical element 4 and the first primary optical element 3 and is emitted to form a second beam. The second beam realizes the high beam function through the projection unit. The lens 5 does not need to be divided for the low beam function and the high beam function, so there is no problem with the appearance of the lamp. The high beam optical unit arranged in front also has the same effect, which will not be elaborated here.
[0075] The second aspect of this application provides a vehicle lamp, which includes the vehicle lamp assembly provided in the first aspect of this application, and therefore possesses all its beneficial effects, which will not be elaborated here.
[0076] The third aspect of this application provides a vehicle including the vehicle lights provided in the second aspect of this application, and therefore possesses all its beneficial effects, which will not be elaborated here.
[0077] The embodiments of this application have been described in detail above with reference to the accompanying drawings, but this application is not limited to the above embodiments. Even if various changes are made to this application, if these changes fall within the scope of the claims of this application and their equivalents, they shall still fall within the protection scope of this application.

8. The vehicle lamp assembly according to any one of claims 1-7, characterized in that, The first light source is a low-light source.
9. The vehicle lighting assembly according to claim 8, characterized in that, The first reflective surface has a cutoff line structure near the boundary of the low light source. The light beam emitted from the low light source is cut off by the cutoff line structure and then converged and reflected by the first reflective surface before being emitted from the first emission surface to form a first light beam that propagates along the optical axis. The first light beam then passes through the projection unit to achieve the low light function.
10. The vehicle lighting assembly according to claim 9, characterized in that, The second reflecting surface is an ellipsoid or a near-ellipsoidal surface, the second light source is located at the first focal point of the second reflecting surface, and the second focal point of the second reflecting surface is located on or within 5 mm of the third reflecting surface.
