Description

Technical Field

[0001] The present invention relates to a vehicle light optical element, in particular to a condenser, and further to a headlamp module having the condenser, a vehicle light having the headlamp module, and a vehicle having the vehicle light. Background Art

[0002] The application of concentrators in car lights started with signal lights, and their application in signal lights has been very mature. Subsequently, concentrators have been increasingly used in car light modules as optical components for low beam or high beam functions. The application of concentrators in car light modules is a major breakthrough, which can greatly improve the optical performance of car light modules. The technology of car light modules using concentrators has continuously produced innovative results, which has continuously improved the comprehensive performance of this type of car light module.

[0003] Figure 1 and Figure 2 A high and low beam integrated vehicle lamp module is provided, comprising a low beam concentrator 1a and a high beam concentrator 2a, wherein a low beam concentrator cutoff line forming structure at a lower edge of a front end of the low beam concentrator 1a and a high beam concentrator cutoff line forming structure at an upper edge of a front end of the high beam concentrator 2a are in contact with each other or are at a small distance (a few tenths of a millimeter) apart, thereby making the low beam light shape well connected with the high beam light shape.

[0004] However, during driving, the headlight vibrates. Since the front ends of the low beam concentrator 1a and the high beam concentrator 2a are in contact or very close to each other, friction between the two causes a certain amount of wear and tear, and even wear to powder, which affects the stability of the light shape emitted by the headlight and reduces the life of the headlight. If the distance between the front ends of the low beam concentrator 1a and the high beam concentrator 2a is increased, the dark area between the low beam shape and the high beam shape will be more obvious.

[0005] Therefore, how to reduce the wear between the low beam concentrator and the high beam concentrator and ensure a uniform transition between the low beam light shape and the high beam light shape has become a technical problem that needs to be solved urgently in this field. Summary of the invention

[0006] The technical problem to be solved by the present invention is to provide a concentrator, which can improve vibration reliability, eliminate wear between optical elements, and achieve good connection between high and low beam light shapes.

[0012] Specifically, the first light output portion is an inner concave curved surface, an outer convex curved surface or a flat surface.

[0052] The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0053] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the said features.

[0054] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "setting", and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0055] It should be understood that, in order to facilitate the description of the present invention and simplify the description, the terms "front and rear" refer to the front and rear directions of the concentrator along the light-emitting direction, which are usually roughly the same as the front and rear directions of the vehicle. For example, the first light-emitting portion 11 is located in the front, and relatively, the first light-incoming portion 14 is located in the rear. The terms "left and right" refer to the left and right directions of the concentrator itself, which are usually roughly the same as the left and right directions of the vehicle during use. The terms "up and down" refer to the up and down directions of the concentrator itself. 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. Therefore, they cannot be understood as limitations on the present invention. Moreover, when the concentrator is installed in a vehicle, it can be installed in various orientations such as the horizontal direction and the vertical direction. The orientation terms of the concentrator of the present invention should be understood in combination with the actual installation state.

[0056] like Figures 3 to 9As shown, the concentrator of the basic embodiment of the present invention includes a first concentrating element 1, an intermediate body 2 and a second concentrating element 3, the middle part of the lower side line of the first light emitting portion 11 of the first concentrating element 1 contacts the middle part of the upper side line of the second light emitting portion 31 of the second concentrating element 3, and a wedge-shaped gap is formed between the first light-transmitting portion 12 of the first concentrating element 1 and the second light-transmitting portion 32 of the second concentrating element 3, the intermediate body 1 is located in the wedge-shaped gap, the first concentrating element 1, the intermediate body 2 and the second concentrating element 3 are an integrally formed part, and the refractive index of the first concentrating element 1 and the refractive index of the second concentrating element 3 are both greater than the refractive index of the intermediate body 2.

[0057] Reference Figure 1 and Figure 2 In the technical solution of the prior art, the low beam concentrator cut-off line forming structure at the lower edge of the front end of the low beam concentrator 1a and the high beam concentrator cut-off line forming structure at the upper edge of the front end of the high beam concentrator 2a are in contact with each other or are at a small distance from each other. Although the low beam light shape and the high beam light shape can be well connected, the headlight vibrates during driving, resulting in certain wear between the low beam concentrator 1a and the high beam concentrator 2a due to friction. In particular, the two are made of the same material, and the wear caused by the friction between the same materials is more serious, and may even cause powdering, thereby reducing the vibration reliability and having a great impact on the low beam and high beam functions of the headlight.

[0058] In view of the technical problems existing in the prior art, the present invention cleverly designs a concentrator, wherein an intermediate body 2 is integrally formed in a wedge-shaped gap between the first concentrating element 1 and the second concentrating element 3, and the first concentrating element 1, the intermediate body 2 and the second concentrating element 3 are integrally formed, so that when vibration occurs, the lower side edge line of the first light emitting portion 11 of the first concentrating element 1 contacts the upper side edge line of the second light emitting portion 31 of the second concentrating element 3, but friction does not occur to cause wear, thereby extending the service life, and, because the ends of the first concentrating element 1 and the second concentrating element 3 are in contact, the light shapes emitted from the two can be evenly connected, and no obvious dark area will appear; in particular, with reference to Fig. 9 The refractive index of the first focusing element 1 and the refractive index of the second focusing element 3 are designed to be greater than the refractive index of the intermediate body 2, so that the light incident on the interface formed between the first focusing element 1 and the intermediate body 2 can be totally reflected, and the light incident on the interface formed between the second focusing element 3 and the intermediate body 2 can also be totally reflected. This design can improve the lighting effect on the one hand, and on the other hand, it can prevent the light in the first focusing element 1 from being emitted from the second light emitting portion 31 of the second focusing element 3 and failing to form a low-beam light cutoff line.

[0059] In order to achieve that the refractive index of the first focusing element 1 and the refractive index of the second focusing element 3 are both greater than the refractive index of the intermediate body 2, transparent optical materials of different materials can be used. For example, the intermediate body 2 can be made of silicone, and the first focusing element 1 and the second focusing element 3 can be made of PC or PMMA materials. The refractive index of silicone material is about 1.423, the refractive index of PC material is about 1.586, and the refractive index of PMMA material is about 1.521.

[0060] In addition, refer to Figure 3 and Figure 5 A protrusion 121 is formed on the lower side of the light incident end of the first light-transmitting portion 12 , and the protrusion 121 can cooperate with the groove 21 on the intermediate body 2 to enhance the bonding strength between the two.

[0061] It should be noted that in Figure 8 In the illustrated embodiment, the end face of the intermediate body 2 is substantially flush with the light incident end of the first light-transmitting portion 12 of the first light-concentrating element 1. Of course, the size of the intermediate body 2 may be reduced so that the end face of the intermediate body 2 is located in front of the light incident end of the first light-transmitting portion 12 of the first light-concentrating element 1. The intermediate body 2 may also be integrally formed with the first light-concentrating element 1 and the second light-concentrating element 3 to prevent wear between the first light-concentrating element 1 and the second light-concentrating element 3 during vibration. Moreover, the intermediate body 2 may also cause total reflection of light incident on the interface formed between the first light-concentrating element 1 and the intermediate body 2 and light incident on the interface formed between the second light-concentrating element 3 and the intermediate body 2, thereby improving the light effect.

[0062] Furthermore, the first light-concentrating element 1 , the intermediate body 2 , and the second light-concentrating element 3 may be integrally formed by using processes such as insert injection molding or two-color injection molding.

[0063] The concentrator of the present invention is used in a headlamp module to realize the high and low beam integrated function, and the first concentrating element 1 is used as a low beam concentrator and the second concentrating element 3 is used as a high beam concentrator as an example for explanation.

[0064] Specifically, refer to Figures 4 to 6 The lower side line of the first light emitting portion 11 forms a first cut-off line structure 13, and the upper side line of the second light emitting portion 31 forms a second cut-off line structure 33. The cut-off inflection point of the first cut-off line structure 13 contacts and overlaps with the cut-off inflection point of the second cut-off line structure 33, so that the emitted low beam light shape and high beam light shape can be well connected.

[0065] Typically, a first light entrance portion 14 is arranged at the light entrance end of the first light-through portion 12, and a second light entrance portion 34 is arranged at the light entrance end of the second light-through portion 32. The number of the first light entrance portions 14 and the second light entrance portions 34 can be selected according to design requirements, so that the first light entrance portions 14 are arranged in a row at the light entrance end of the first light-through portion 12 along the left-right direction, and the second light entrance portions 34 are arranged in a row at the light entrance end of the second light-through portion 32 along the left-right direction; the first light entrance portion 14 and the second light entrance portion 34 can be selected as focusing cups or other focusing mechanisms, such as a convex structure convex backwards. Specifically, Figure 3 A specific embodiment of the first light entrance portion 14 and the second light entrance portion 34 using a focusing cup is shown, and a concave cavity is opened at the light entrance end of the focusing cup. The side wall of the concave cavity can be a cone that shrinks from the outside to the inside, and the bottom of the concave cavity can be a curved surface that convexes outward, so that the light emitted by the light source can be collected and converged, and the light is incident on the first light entrance portion 14 and the second light entrance portion 34, with better lighting effect.

[0066] In addition, the first light output portion 11 can be a concave surface, a convex surface or a plane, preferably a concave surface. This design can make the curvature of the first light output portion 11 the same or approximately the same as the actual object-side focal plane curvature of the lens 4. The advantage of such a design is that the so-called focal plane refers to a plane orthogonal to the optical axis of the lens. However, due to the field curvature difference, the focal plane of the lens is actually a curved surface that is concave backwards, which makes the closer the light source is to the focal plane, the clearer the light pixels formed by the lens, and the farther the light source is from the focal plane, the blurrier the light pixels formed by the lens; therefore, setting the first light output portion 11 as a concave surface can form a clear light shape; similarly, the second light output portion 31 can be a concave surface, a convex surface or a plane, preferably a concave surface.

[0067] In order to facilitate understanding of the technical concept and advantages of the concentrator of the present invention, the following Figures 3 to 9 A relatively comprehensive structural form is described with relatively preferred features of the present invention.

[0068] like Figures 3 to 9As shown, the concentrator of the preferred embodiment of the present invention comprises a first concentrating element 1, an intermediate body 2 and a second concentrating element 3, the first concentrating element 1 comprises a first light input portion 14, a first light passing portion 12 and a first light output portion 11, each of the first light input portions 14 is arranged in a row at the light input end of the first light passing portion 12 along the left-right direction, and the light output end of the first light passing portion 12 forms the first light output portion 11, the second concentrating element 3 comprises a second light input portion 34, a second light passing portion 32 and a second light output portion 31, each of the second light input portions 34 is arranged in a row at the light input end of the second light passing portion 32 along the left-right direction, and the light output end of the second light passing portion 32 forms the second light output portion 31, and the lower side line of the first light output portion 11 forms a first cut-off line structure. The first cut-off line structure 13 is formed in the upper side of the second light-emitting portion 31 as a second cut-off line structure 33. The first cut-off line structure 13 contacts the second cut-off line structure 33, so that a wedge-shaped gap is formed between the first light-transmitting portion 12 and the second light-transmitting portion 32. The intermediate body 2 is located in the wedge-shaped gap, and the first light-concentrating element 1, the intermediate body 2 and the second light-concentrating element 3 are integrally formed. An interface is formed between the intermediate body 2 and the first light-transmitting portion 12 and the second light-transmitting portion 32. The intermediate body 2 is made of silicone material, and the first light-concentrating element 1 and the second light-concentrating element 3 are made of PMMA or PC material, so that the refractive index of the first light-concentrating element 1 and the refractive index of the second light-concentrating element 3 are both greater than the refractive index of the intermediate body 2.

[0069] It can be seen from the above preferred embodiments that after the above concentrator is applied to a specific optical module to form a headlamp module with integrated high and low beams, the light emitted by the light sources corresponding to each first light input portion 14 is converged through the corresponding first light input portion 14 and injected into the first light-transmitting portion 12, a part of the light is directly emitted by the first light output portion 11, and the other part of the light is emitted on the interface formed between the first light-transmitting portion 12 and the intermediate body 2 and is totally reflected, and then emitted by the first light output portion 11 to form a low beam light shape, the light emitted by the light sources corresponding to each second light input portion 34 is converged through the corresponding second light input portion 34 and injected into the second light-transmitting portion 32, a part of the light is directly emitted by the second light output portion 31, and the other part of the light is emitted on the interface formed between the second light-transmitting portion 32 and the intermediate body 2 and is totally reflected, and then emitted by the second light output portion 31 to form a high beam light shape, and the middle part of the first cut-off line structure 13 is in contact with the middle part of the second cut-off line structure 33, so that the low beam light shape and the high beam light shape can be well transitioned and connected when they are emitted at the same time. In addition, since the first light-focusing element 1, the intermediate body 2 and the second light-focusing element 3 are integrally formed, the first light-focusing element 1 and the second light-focusing element 3 will not move relative to each other during vibration, that is, no friction will occur between the two, thereby avoiding wear between the two, extending the service life, and greatly improving vibration reliability; moreover, the assembly error between the first light-focusing element 1 and the second light-focusing element 3 is avoided, and the relative position accuracy of the low beam optical system and the high beam optical system is improved, thereby making the connection between the low beam light shape and the high beam light shape good and eliminating dark areas.

[0070] like Figures 10 to 17 As shown, the concentrator of the present invention is applied to the optical module to obtain the headlamp module of the present invention, and the inflection point of the lower side line of the first light emitting portion 11 coincides with the inflection point of the upper side line of the second light emitting portion 31, and is located in the focal area of ​​the lens 4; the inflection point of the lower side line of the first light emitting portion 11 here refers to the cutoff inflection point of the first cutoff line structure 13 of the first light emitting portion 11, corresponding to the inflection point of the low beam cutoff line, and the inflection point of the upper side line of the second light emitting portion 31 refers to the cutoff inflection point of the second cutoff line structure 33 of the second light emitting portion 31, corresponding to the inflection point of the high beam cutoff line.

[0071] Furthermore, a low beam zone III forming structure 5 can be provided in the lower area of ​​the lens 4, which has a simple structure, is easy to process, is not easy to interfere with other parts, and has more stable optical performance. Preferably, the low beam zone III forming structure 5 can be composed of a plurality of convex and / or concave convex structures arranged in a row.

[0072] The embodiment of the vehicle lamp of the present invention may have the headlamp module described in any of the above embodiments; that is, all the technical solutions of all the above embodiments of the headlamp modules are adopted, and therefore at least all the beneficial effects brought by the technical solutions of the above embodiments of the headlamp modules are possessed.

[0074] The preferred embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited thereto. Within the technical concept of the present invention, the technical solution of the present invention can be subjected to a variety of simple modifications, including the combination of various specific technical features in any suitable manner. In order to avoid unnecessary repetition, the present invention will not further describe various possible combinations.
