[0002] With the continuous development of the automotive lighting industry, the requirements for automotive lighting are getting higher and higher. The current high beam lighting system generally adopts a reflective or projective high beam lighting system. The reflective high beam lighting system uses a reflective surface formed by a parabola to collimate the divergent light emitted by a light source set at the focus of the reflective surface, thereby forming a nearly parallel lighting beam. The projective high beam lighting system uses a reflective surface formed by an ellipsoid to converge the divergent light emitted by a light source set at the first focus of the reflective surface to the second focus, and then collimates and calibrates it through a collimating device such as a convex lens with a focus set at the second focus of the reflective surface, forming a nearly parallel lighting beam.
[0003] In order to achieve the illumination value required by the high beam regulations, the reflective high beam lighting system of the prior art requires a reflector with a large focal length, which results in a large reflector size and a large size of the reflective high beam lighting system. In addition, the large size and large focal length reflector also wastes light energy and cannot achieve a high beam widening light type. The illumination value of the outgoing light of the projection high beam lighting system of the prior art is affected by the focal length of the ellipsoid and the focal length of the lens, resulting in a large front and rear size of the optical system. The large size of the optical system is not conducive to the installation of the whole vehicle and the appearance design of the headlights.

DETAILED DESCRIPTION
[0030] 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 here is only used to illustrate and explain the present invention, and is not used to limit the present invention.
[0031] In the present invention, unless otherwise stated, the terms such as "first" and "second" are used to distinguish one element from another, and do not have order and importance, and do not constitute a limitation on the scope of protection of the present invention. The terms "installation" 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 this application can be understood according to specific circumstances. The "widening light type" mentioned in the present invention refers to the lighting range light type that meets the requirements of the high beam regulations, and the "center light type" refers to the lighting light type of the Emax value that meets the requirements of the high beam regulations, which is obvious to ordinary technicians in this field. Because the actual light source is not a point light source, the parallel light involved in the present invention is not strictly parallel, but close to parallel, just for the convenience of explanation and understanding. In addition, the "focal length of the first reflection surface 301 is 2mm" and the "focal length of the second reflection surface 302 is 5mm" mentioned in the embodiment of the present invention are only for the convenience of explanation and do not constitute a limitation on the scope of protection of the present invention.
[0032] like Figures 1 to 5 As shown, the present application provides a high-beam lighting system, including a circuit board 1, a reflective element 3, a lens 4, and a light source 2 disposed on the circuit board 1 for emitting a light beam, the reflective element 3 including a first reflective surface 301 and a second reflective surface 302, the focal length of the first reflective surface 301 is smaller than the focal length of the second reflective surface 302, and the first reflective surface 301 is closer to the light source 2 than the second reflective surface 302, and the lens 4 includes a first lens portion 401 corresponding to the first reflective surface 301;
[0033] When the high-beam lighting system is in use, a portion of the light beam emitted by the light source 2 is reflected by the first reflecting surface 301 and then projected through the first lens portion 401 to form a first lighting light type portion 5; and another portion of the light beam is reflected by the second reflecting surface 302 to form a second lighting light type portion 6. The first lighting light type portion 5 and the second lighting light type portion 6 are superimposed to form a high-beam lighting light type.
[0034] It should be noted that if Fig. 9 As shown, in actual use, the light source is not a point light source. For example, a light source with a certain size emits a light beam. After the light beam is reflected by a reflective surface far from the light source, a light beam β with a small illumination range is generated, that is, the light spot generated is small. After the light beam is reflected by a reflective surface close to the light source 2, a light beam α with a large illumination range is generated, that is, the light spot generated is large. Since the luminous flux of the two regions with different illumination ranges is the same, the illumination range of the light beam β has a higher brightness value than the illumination range of the light beam α. In high beam, both the light beam β and the light beam α will have part of the light beam reflected to the HV point of the high beam light type, so that the brightness value at the HV point meets the high beam regulations. Among them, the light beam β is more reflected to the HV point, and it contributes more to the brightness value at the HV point. The light beam α is more reflected near the HV point, and the closer the reflection surface is to the light source 2, the farther the light beam is from the HV point. Finally, the light beam emitted by the light source is reflected by the reflective surface. The light type obtained is a light spot with a high central brightness value and a large illumination range, but the surrounding parts of the light spot are mostly useless, that is, a waste of light energy is generated. The HV point referred to in this article is a light distribution screen that is vertically set 25 meters in front of the vehicle, and is the focus of the HH axis and the VV axis on the light distribution screen.
[0035] Under the condition that the light source has the same solid angle, in the present application, although the second reflecting surface 302 is smaller in size and focal length than the reflector of the reflective high beam lighting system of the prior art, the second lighting light type portion 6 formed by its reflection has a sufficient illumination value at the HV point, that is, a central light type that meets the high beam requirements is obtained; in addition, in order to avoid the problem of light energy waste in the partial light type obtained by reflecting the part of the reflecting surface closer to the light source 2 when the entire reflecting element 3 is set as the second reflecting surface 302, the present application sets the part of the reflecting surface closer to the light source 2 as the first reflecting surface 301, the first reflection surface 301 is a reflection surface with a smaller focal length. After the light beam is reflected by the first reflection surface 301, a larger primary light spot is obtained, and then after being converged by the first lens portion 401, a widened light type that meets the requirements of the high beam is obtained. It can be said that the setting of the first reflection surface 301 and its corresponding first lens portion 401 not only solves the problem of light energy waste caused by setting the entire reflection element 3 as the second reflection surface 302, but also performs secondary light distribution on this part of the light beam, converting it into a widened light type that meets the requirements of the high beam, and there is no need to set up an additional optical system to achieve the widened light type of the high beam.
[0036] As a specific implementation, the first reflecting surface 301 and the second reflecting surface 302 are both parabolic surfaces, and the focus of the first reflecting surface 301 and the focus of the second reflecting surface 302 coincide with the light source 2. A portion of the light beam emitted by the light source 2 is reflected by the first reflecting surface 301 to form a nearly parallel reflected light that enters the first lens portion 401, and then forms the first lighting light type portion 5 through the projection of the first lens portion 401. The first lighting light type portion 5 is a light spot with high illumination and a large illumination range. Another portion of the light beam emitted by the light source 2 is reflected by the second reflecting surface 302 to form a nearly parallel light beam, and then forms the second lighting light type portion 6. The nearly parallel light beam is more concentrated and more directed to the HV point, so the second lighting light type portion 6 has a higher illumination and can illuminate farther during high beam illumination. It should be noted that the focus of the first reflecting surface 301 and the focus of the second reflecting surface 302 do not absolutely coincide with the light source 2, that is, the focus of the first reflecting surface 301 can be set to be located at or near the position of the light source 2, and the focus of the second reflecting surface 302 can be set to be located at or near the position of the light source 2. The nearby position can be selected according to actual conditions and is not further limited in this application.
[0037] As another specific implementation, the first reflection surface 301 is an ellipsoidal surface, the second reflection surface 302 is a parabola, and the first focus of the first reflection surface 301 and the focus of the second reflection surface 302 coincide with the light source 2. A part of the light beam emitted by the light source 2 converges to the second focus of the first reflection surface 301 through reflection by the first reflection surface 301, and then enters the first lens portion 401 to form the first illumination light type portion 5 through the projection of the first lens portion 401. The first illumination light type portion 5 is a light spot with high illumination and a large illumination range. Another part of the light beam emitted by the light source 2 forms a nearly parallel light beam through reflection by the second reflection surface 302, and then forms the second illumination light type portion 6. The nearly parallel light beam is more concentrated and more directed to the HV point, so the second illumination light type portion 6 has high illumination and a long illumination distance. It should be noted that the first focus of the first reflecting surface 301 and the focus of the second reflecting surface 302 coincide with the light source 2, which means that the first focus of the first reflecting surface 301 can be set to be located at or near the position of the light source 2, and the focus of the second reflecting surface 302 can be set to be located at or near the position of the light source 2. The nearby position can be selected according to actual conditions and is not further limited in this application.
[0038] As a preferred embodiment, the first reflecting surface 301 which is an ellipsoidal surface also has a second focus, and the second focus is set to be located on the light incident surface of the first lens portion 401. As a result, a part of the light beam emitted by the light source 2 is reflected to the second focus through the first reflecting surface 301, and then projected through the first lens portion 401 to form the first lighting light type portion 5, and the light beam reflected by the first reflecting surface 301 converges on the light incident surface of the first lens portion 401, thereby reducing the front and rear dimensions of the high beam lighting system. It should be noted that the second focus is set to be located on the light incident surface of the first lens portion 401, which means that the light incident surface of the first lens portion 401 is set at the position of the second focus of the first reflecting surface 301 or at a position near the second reflecting surface. The nearby position can be selected according to actual conditions, and this application does not make further restrictions.
[0039] As a preferred embodiment, the first lens portion 401 includes a first curved surface 4011 and a second curved surface 4012, the first curved surface 4011 is the light incident surface of the first lens portion 401, the second curved surface 4012 is the light exit surface of the first lens portion 401, and the focus formed by the first curved surface 4011 and the second curved surface 4012 is set to be located on the first reflective surface 301, so as to avoid defocusing and further increase the brightness of the first lighting light type portion 5. It should be noted that the focus formed by the first curved surface 4011 and the second curved surface 4012 is set to be located on the first reflective surface 301 or at a position near the first reflective surface 301, and the nearby position can be selected according to actual conditions, and this application does not make further restrictions.
[0040] As a preferred embodiment, the lens 4 also includes a second lens portion 402 corresponding to the second reflective surface 302, and another part of the light beam is reflected by the second reflective surface 302 and then projected through the second lens portion 402 to form a second illumination light type portion 6. As a specific selected embodiment, the first lens portion 401 is a focusing lens portion, and the second lens portion 402 is an equal-thickness lens portion. Thus, a part of the light beam emitted by the light source 2 is reflected by the first reflective surface 301, and then focused by the first lens portion 401 to form the first illumination light type portion 5, and another part of the light beam emitted by the light source 2 is reflected by the second reflective surface 302, and then projected through the second lens portion 402 to form the second illumination light type portion 6. The second lens portion 402 is an equal-thickness lens portion, so that the incident light beam is almost not deflected, and then it is only necessary to adjust the emission direction of the light beam reflected by the second reflective surface 302, thereby reducing the difficulty of installation. It should be noted that the present application adopts a lens portion of equal wall thickness as the second lens portion 402, so that the emission direction of the light beam can be changed by simply adjusting the reflection direction of the light beam by the second reflecting surface 302, thereby changing the formation position of the second illumination light type portion 6. However, it is obvious to a person skilled in the art that the second lens portion 402 can also be set as a lens with an arc and / or an inclination angle, so as to cooperate with the second reflecting surface 302 to change the emission direction of the light beam. It will not be elaborated here, and all belong to the protection scope of the present invention.
[0041] As a preferred embodiment, the reflective element 3 is an integrally molded part, the lens 4 is an integrally molded part, the end of the second lens portion 402 and the second reflective surface 302 support and cooperate with each other, so that the reflective element 3 and the lens 4 are relatively fixed, thereby ensuring that the light beam emitted by the light source 2 can stably pass through the reflective element 3 and the lens 4 to form the first lighting light type part 5 and the second lighting light type part 6, and the reflective element 3 and the lens 4 are respectively integrally molded parts, which can simplify production and assembly and reduce costs.
[0042] As a preferred embodiment, Figures 6 to 8 As shown, the focal length of the first reflecting surface 301 is set to a first predetermined focal length, so that the first illumination light type portion 5 is a widening light type, and the focal length of the second reflecting surface 302 is set to a second predetermined focal length, so that the second illumination light type portion 6 is a center light type. It is obvious to those skilled in the art that the first predetermined focal length can be set to a variety of values, so that the first illumination light type portion 5 is a widening light type a with a larger illumination range, and the second predetermined focal length can also be set to a variety of values, so that the second illumination light type portion 6 is a center light type b with a higher illumination value, so that the widening light type a and the center light type b are superimposed to form a high-beam illumination light type that meets the illumination and illumination range requirements of high-beam regulations, and there is no need to separately set up an optical system for forming the widening light type.
[0043] As a specific implementation, the focus formed by the cooperation of the first curved surface 4011 and the second curved surface 4012 is set at a predetermined position, and the emission direction of the second reflecting surface 302 is set to a predetermined direction, so that the first lighting light type portion 5 and the second lighting light type portion 6 can cooperate with each other to form a high-beam lighting light type. By adjusting the focus position formed by the cooperation of the first curved surface 4011 and the second curved surface 4012 and the emission direction of the second reflecting surface 302, the first lighting light type portion 5 and the second lighting light type portion 6 can cooperate with each other to form a high-beam lighting light type, thereby obtaining the following Figure 8 It is obvious to those skilled in the art that the predetermined position can be a variety of positions, and the predetermined direction can be a variety of directions, as long as the first lighting light type portion 5 and the second lighting light type portion 6 are superimposed to form a lighting light type that complies with high beam regulations, they all fall within the protection scope of the present invention.
[0044] On the basis of the high-beam lighting system mentioned in the above technical solution of the present invention, the present invention provides a vehicle lamp, the high-beam lighting system of the vehicle lamp has a smaller size and a higher light efficiency.
[0045] In addition, the high beam lighting system of the present invention can be arranged in multiple layers or multiple rows, which also falls within the protection scope of the present application. For example, the present application provides an embodiment of a preferred high beam lighting system, such as Figures 1 to 3As shown, it includes two high-beam lighting systems connected side by side, each high-beam lighting system includes a heat sink 7 and a circuit board 1 arranged on the heat sink 7, a light source 2 for emitting a light beam is arranged on the circuit board 1, and the high-beam lighting structure also includes a reflective element 3 and a lens 4, a portion of the reflective element close to the light source 2 forms a first reflective surface 301, and a portion away from the light source forms a second reflective surface 302, the focal length of the first reflective surface 301 is smaller than the focal length of the second reflective surface 301, for example, the focal length of the first reflective surface 301 is 2mm, and the focal length of the second reflective surface 302 is 5mm, so that compared with the reflective surface with a focal length of 15mm of the traditional reflective high-beam lighting system, the high-beam lighting system of the present invention is smaller in size, easy to install on the whole vehicle and design the appearance of the headlight, and at the same time reduces the production cost. The lens 4 includes a first lens portion 401 corresponding to the first reflective surface 301 and a second lens portion 402 corresponding to the second reflective surface 302. A part of the light beam emitted by the light source 2 is reflected by the first reflection surface 301 and then projected through the first lens portion 401 to form a first illumination light type portion 5, and another part of the light beam is reflected by the second reflection surface 302 and then projected through the second lens portion 402 to form a second illumination light type portion 6. The first illumination light type portion 5 and the second illumination light type portion 6 are superimposed to form a high-beam illumination light type. Among them, the second reflection surface 302 is far away from the light source 2, so the second illumination light type portion 6 is a central light spot with a high illumination value. The first reflection surface 301 is close to the light source 2, so the high-beam lighting system uses the first reflection surface 301 with a small focal length to form a primary light spot with a large illumination range, and then the first lens portion 401 projects to form a first illumination light type portion 5 with a large illumination range and a large illumination. The first reflection surface 301 and the second reflection surface 302 can both be parabolic surfaces, and the focus of the first reflection surface 301 and the focus of the second reflection surface 302 coincide with the light source 2. The focal length of the first reflection surface 301 is set to a first predetermined focal length, and the focal length of the second reflection surface 302 is set to a second predetermined focal length. Thus, the light beam emitted by the light source 2 passes through the first reflecting surface 301 and the second reflecting surface 302 to form a nearly parallel light beam. The first lens portion 401 is a focusing lens, and the second lens portion 402 is an equal-thickness lens. After being reflected by the first reflecting surface 301, the nearly parallel light beam is focused by the first lens portion 401 to form the first illumination light type portion 5. The first illumination light type portion 5 is a widening light type a with a large illumination range. After being reflected by the second reflecting surface 302, the nearly parallel light beam is projected by the second lens portion 402 and more toward the HV point, thereby forming a second illumination light type portion 6 with a relatively concentrated light beam and a high illumination value. The second illumination light type portion 6 is a central light type b with a high illumination value. The first lens portion 401 includes a first arc surface 4011 and a second arc surface 4012. Figure 2 and Figure 3As shown, the focus formed by the cooperation of the first arc surface 4011 and the second arc surface 4012 is set to be located on the first reflective surface 301, so as to avoid defocusing, thereby further increasing the illumination of the widening light type a, and the widening light type a and the central light type b are superimposed on each other to form Figure 8 The high beam lighting light type shown in the figure complies with the high beam regulations, and the high beam lighting system is small in size. In addition, the reflective element 3 is an integrally formed part, the lens 4 is an integrally formed part, and the end of the second lens portion 402 and the second reflective surface 302 support and cooperate with each other, so that the reflective element 3 and the lens 4 are relatively fixed, thereby simplifying the production and installation of the high beam lighting system, and the connection is stable, and the high beam lighting light type can be relatively stably generated. It should be noted that the second curved surface 4012 arranged side by side on the left and right of this preferred embodiment can be connected to form a complete curved surface, which is respectively matched with the first curved surface 4011 on the left and the first curved surface 4011 on the right to form a focus on the corresponding first reflective surface 301, and the first curved surface 4011 on the left and the first curved surface 4011 on the right share a second curved surface 4012 formed by connection. It is obvious to those skilled in the art that a second curved surface 4012 can be separately set for each first curved surface 4011 to cooperate with it, or multiple first curved surfaces 4011 can cooperate with a second curved surface 4012 formed by connection, or the above two methods are combined, all of which belong to the scope of protection of the present invention.
[0046] It can be seen from the above description that the advantages of the present invention are: first, the size of the high beam lighting system is smaller while meeting the high beam regulations, which is convenient for vehicle installation and headlight appearance design. Second, the high beam lighting system has high light efficiency. Third, the high beam lighting system is easy to produce and install, low in cost, and easy to commercialize. Fourth, the high beam lighting system has a stable structure that can ensure the relative position accuracy between the light source, reflector and lens in the high beam lighting system, thereby ensuring that the high beam lighting system emits a light type that meets the requirements of the high beam regulations.
