[0050] In order to make the above-mentioned objects, features and advantages of the present application more obvious and easy to understand, the specific implementation methods of the present application are described in detail below with reference to the accompanying drawings.
[0051] In the following description, many specific details are set forth to facilitate a full understanding of the present application, but the present application may also be implemented in other ways different from those described herein, and therefore the present application is not limited to the specific embodiments disclosed below.
[0052] As shown in this application and claims, unless the context clearly indicates an exception, the words "a", "an", "an" and / or "the" do not refer to the singular and may also include the plural. Generally speaking, the terms "include" and "comprise" only indicate the inclusion of the steps and elements that have been clearly identified, and these steps and elements do not constitute an exclusive list. The method or device may also include other steps or elements.
[0053] In the description of the present application, it should be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, upright, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present application and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the devices or elements referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present application. The directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.
[0054] In addition, it should be noted that the use of words such as "first" and "second" to define components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above words have no special meaning and cannot be understood as limiting the scope of protection of this application. In addition, although the terms used in this application are selected from well-known and commonly used terms, some terms mentioned in the specification of this application may be selected by the applicant at his or her discretion, and their detailed meanings are explained in the relevant parts of the description of this article. In addition, it is required to understand this application not only by the actual terms used, but also by the meaning implied by each term.
[0055] However, the dimensions or positional relationships of the components shown in the drawings are sometimes exaggerated for the purpose of clarifying the description. Furthermore, in the following description, for the same names and symbols, representing the same or homogeneous components, it is appropriate to omit their detailed description. Furthermore, the various elements constituting the present application may be in the form of a plurality of elements constituted by the same components so that one component serves as a plurality of elements, or conversely, it may be realized by a plurality of components sharing the function of a component. In addition, the contents described in some embodiments and implementation methods may also be utilized in other embodiments, implementation methods, etc. In addition, in this specification, "on" is not limited to the case where it is formed in contact with the upper surface, but also includes the case where it is formed separately on the upper surface, and is also used to include the meaning of the existence of an intervening layer between layers.
[0056] It should be understood that, in order to simplify the description, the terms "upstream, downstream" refer to the upstream and downstream directions along the light emitting direction, that is, the light emitting surface 221 is located downstream, and relatively, the light incident surface 211 is located upstream; the terms are based on the orientation or positional relationship shown in the accompanying drawings, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the application; moreover, when the optical units are assembled to form a high beam module, they can be installed in various orientations such as horizontal and vertical directions. The orientation terms of the optical elements of this application should be understood in combination with the actual installation status.
[0057] The "high beam" described below refers to the high beam of the vehicle, which is used to illuminate the vehicle at a longer distance ahead. The high beam module is an optical module that constitutes the high beam lighting function of the vehicle.
[0058] refer to Figures 9 to 14 As shown, in some embodiments, the high beam lamp module 100 includes one or more independent high beam optical units 10, including one or more first high beam optical units 101, and / or one or more second high beam optical units 102. The difference between the first high beam optical unit 101 and the second high beam optical unit 102 is that the light type is different, one is, for example, Figure 4The converging light type shown, the other is for example Figure 8 The diffuse light type shown is matched with a high beam function that meets regulations and customer needs by combining different numbers of these two small-sized modular high beam optical units. The specific differences between the first high beam optical unit 101 and the second high beam optical unit 102 will be specifically introduced below.
[0059] For example Figures 9 to 11 In the illustrated embodiment, the high beam lamp module 100 has three first high beam optical units 101 and one second high beam optical unit 102, but this is not limiting. For example, all of them may be first high beam optical units 101, or all of them may be second high beam optical units 102. The arrangement is also not limited to the arrangement shown in the figure. For example, the first high beam optical units 101 and the second high beam optical units 102 may be arranged adjacently and staggered in the vertical direction, that is, one first high beam optical unit 101, one second high beam optical unit 102, one first high beam optical unit 101, one second high beam optical unit 102, and so on. The one or more high beam optical units 10 of the high beam lamp module 100 are arranged and distributed in the vertical direction, and the width of the high beam lamp module 100 is the width of a single high beam optical unit 10, that is, the maximum width of the high beam lamp module 100 is limited by the width of a single high beam optical unit 10, so that the requirement for the size of the lighting system to be smaller and smaller can be met.
[0060] In addition, if Figure 12 to Figure 14 As shown, in some embodiments, as Fig.12 As shown, the high beam module 100 may also include a whole optical lens 20 disposed downstream of the plurality of arranged high beam optical units 10. The beneficial effect of disposing the optical lens 20 is that, in order to reflect the flexibility of the high beam module 100 when used as a small module, it can be applied to different styling requirements, whether you want to reflect the overall effect or like to see the effect of each module small unit. It can be understood that the optical lens 20 can also be disposed downstream of some high beam optical units to achieve the overall effect of some parts and the effect of some high beam optical units one by one.
[0061] The dimensions of the high beam optical unit 10 in the figure are 30 mm in length and 15 mm in width, but this is not a limitation. Preferably, the dimensions of the high beam optical unit 10 are 10 mm-20 mm in width and 20 mm-40 mm in length, which can better meet the size restriction conditions.
[0062] The meaning of "independent" here is that each high beam optical unit 10 is manufactured separately, and multiple high beam optical units 10 manufactured separately are assembled to form a high beam optical module, rather than being integrally formed. The structure of the high beam optical module 100 can be assembled according to the diversified requirements of the actual product shape, for example, different numbers of first high beam optical units 101 and / or second high beam optical units 102 can be combined to achieve the miniaturization of the vehicle high beam related structure, and meet the diversified requirements of different vehicle shapes, shorten the product development cycle and reduce the production cost.
[0063] refer to Figures 1 to 11 As shown, the high-beam optical unit 10 includes a light source 1 and a corresponding optical light distribution component 2 .
[0064] The light source 1 is a component that provides light, and may be, for example, an LED light source, but is not limited thereto. It is understood that the number of light sources 1 is not limited to Figure 1 One of the following, or Figure 6 The three shown are limits and can be adjusted based on actual needs.
[0065] The optical light distribution component 2 can be understood as an optical lens. The optical light distribution component 2 includes a light focusing portion 21 and a light guiding portion 22 arranged in sequence from upstream to downstream. The upstream end surface of the light focusing portion 21 provides a light incident surface 211 of the high beam optical unit 10, and the downstream end surface of the light guiding portion 22 provides a light exit surface 221 of the high beam optical unit 10. Among them, the light path provided by the high beam optical unit 10 includes that the light emitted by the light source 1 enters the optical light distribution component 2 through the light incident surface 211, converges to the corresponding focus 222 located at the light guiding portion 22 through the reflective surface 212 of the light focusing portion 21, and the light continues to propagate and exits through the light exit surface 221.
[0066] like Figures 1 to 3 ,as well as Figures 5 to 7 As shown, the focusing portion 21 may include a light incident surface 211 and a reflection surface 212. The light incident surface 211 is a surface for receiving light emitted from the light source 1, and the reflection surface is a surface for reflecting the incident light. For example, the reflection surface may be a total reflection surface with a converging effect, such as an ellipsoidal surface. The meaning of the surface focus 222 is similar to the common meaning in the art, that is, when light passes through the lens parallel to the main axis, it converges to a point on the main optical axis, as shown in the figure. Figure 1 , Figure 5 As shown, in the horizontal direction, the focus 222 and the light source 1 are substantially coaxially distributed. The light guide portion 22 is a light-conducting element, and its material can be, for example, transparent PC, PMMA, and the like.
[0067] like Figure 1 as well as Figure 4As shown, the light guide portion 22 of the first high-beam optical unit 101 has a converging structure 2201 to form a converging light pattern.
[0068] like Figure 5 as well as Figure 8 As shown, the light guide portion 22 of the second high beam optical unit 102 has a diffusion structure 2202 to form a diffused light pattern. The converging structure 2201 and the diffusion structure 2202 herein, for example, the converging structure 2201 may be a structure in which a collimator is provided in the light guide portion 22, such as a groove, a curved surface, etc., so that the light passes through while the light remains parallel, and the diffusion structure 2202 is a structure in which no collimator is provided in the light guide portion 22, so that the light naturally diverges. Figure 1 The light path of the converging light type shown, and Figure 5 The divergent light paths shown can help to understand these two light types.
[0069] That is, for the first high-beam optical unit 101, the optical path provided is that the light emitted by the light source 1 enters the light-collecting portion 21, is converged to the corresponding focus 222 located at the light-guiding portion 22 through the reflective surface 212 of the light-collecting portion 21, and the light continues to propagate through the converging structure 2201 and is emitted through the light-emitting surface 221. Similarly, for the second high-beam optical unit 102, the optical path provided is that the light emitted by the light source 1 enters the light-collecting portion 21, is converged to the corresponding focus 222 located at the light-guiding portion 22 through the reflective surface 212 of the light-collecting portion 21, and the light continues to propagate through the light-emitting surface 221 and is emitted through the diffusing structure 2202.
[0070] The beneficial effect of adopting the high beam lamp module introduced in the above embodiment is that by combining the compact first high beam optical unit 101 and / or the second high beam optical unit 102, the miniaturization of the vehicle high beam lamp related structure can be achieved, and the diversified requirements of different vehicle shapes can be met, thereby shortening the product development cycle and reducing the production cost.
[0071] Continue to refer Figure 1 , Figure 3 as well as Figure 5 , Figure 7 As shown, in some embodiments, the structure of the light focusing portion 21 can also be that the reflective surface 212 of the light focusing portion 21 constitutes the side wall of the light focusing portion 21, and the first optical pattern 2121 is arranged on the side wall, so that the beneficial effect is that stray light can be eliminated to improve the light effect. It can be understood that the specific position of the first optical pattern 2121 is not limited to being arranged at both ends in the width direction as shown in the figure, and can also be other positions, which can be flexibly adjusted according to specific light effect requirements. The position in the figure is only to more clearly show the first optical pattern 2121.
[0072] like Figure 7As shown, the second high-beam optical unit 102 has three light-concentrating portions 21 connected together, each of the three light-concentrating portions 21 corresponds to a light source, and the three light-concentrating portions 21 are integrated into a whole, and the first optical patterns 2121 are provided on both sides thereof.
[0073] refer to Figure 1 , Figure 2 as well as Figure 5 , Figure 6 As shown, in some embodiments, the side surface of the light guide portion 22 in the width direction has a second optical pattern 223, which has the beneficial effect of eliminating stray light to improve light efficiency. The "side surface" here is relative to the concept of the "end surface" of the light guide portion 22, and the "side surface" here is located on both sides of the end surface as the light emitting surface 221 in the width direction.
[0074] refer to Figure 2 as well as Figure 6 As shown, in some embodiments, the light emitting surface 221 of the light guide portion 22 has a third optical pattern 2211. This has the beneficial effect of adjusting the light spot size and making the light spot more uniform, that is, the structure of the third optical ring pattern can be adjusted according to actual light effect requirements to obtain the required light spot size.
[0075] It can be understood that the present application also provides a vehicle lamp, which can have the high beam lamp module described in any of the above embodiments, and at least has all the beneficial effects brought by the technical solution of the above high beam lamp module embodiment. In addition, the present application also provides a vehicle, which can have the above vehicle lamp, and also has all the beneficial effects brought by the technical solution of the above high beam lamp module embodiment.
[0076] In addition, the high beam optical unit 10 introduced above includes the first high beam optical unit 101 or the second high beam optical unit 102, which can be used as the smallest unit for assembling the high beam lamp module 100 to achieve the miniaturization of the vehicle high beam lamp related structure and meet the diversified requirements of different vehicle shapes, shorten the product development cycle and reduce the production cost.
[0077] In summary, the beneficial effects of the high beam optical unit, high beam lamp module, headlight and vehicle of the present application include but are not limited to miniaturization of the vehicle high beam lamp related structure, meeting the diverse requirements of different vehicle shapes, shortening the product development cycle and reducing production costs.
[0078] Although the present application has been described with reference to the current specific embodiments, ordinary technicians in this technical field should recognize that the above embodiments are only used to illustrate the present application, and various equivalent changes or substitutions may be made without departing from the spirit of the present application. Therefore, as long as the changes and modifications to the above embodiments are within the essential spirit of the present application, they will fall within the scope of the claims of the present application.
