Description

TECHNICAL FIELD

[0001] The present disclosure relates to the field of vehicle lighting, and specifically to a vehicle lamp module and a vehicle lamp.BACKGROUND

[0002] Nowadays, people have changed the original engine bay position of more and more electric vehicles to the trunk space, which puts higher requirements on the front-rear dimension of the headlamp module. The smaller the front-rear dimension is, the larger the trunk space is. For an existing headlamp module, generally a quasi-ellipsoidal reflector is configured to converge light emitted by a light source set at a near focus of a quasi-ellipsoidal surface to a far focus thereof. The far focus of the quasi-ellipsoidal surface is set at the focus of a convex lens, that is, the light spot formed at the focus of the convex lens is imaged through the convex lens. However, this results in a large dimension of the headlamp module in the front-rear direction, which cannot meet the demand for a larger trunk space.SUMMARY

[0028] In order to make the objectives, technical solutions, and advantages of the embodiments of the present disclosure clearer, the technical solution in the embodiments of the present disclosure will be clearly and completely described below with reference to the drawings in the embodiments of the present disclosure. Obviously, the embodiments described are only some not all embodiments of the present disclosure. The components of embodiments of the present disclosure generally described and illustrated in the drawings herein may be arranged and designed in a variety of different configurations.

[0029] Accordingly, the following detailed description of embodiments of the present disclosure provided in the drawings is not intended to limit the scope of the claimed present disclosure but merely represents selected embodiments of the present disclosure. All other embodiments derived by a person of ordinary skill in the art based on the embodiments of the present disclosure without inventive efforts shall fall within the scope of protection of the present disclosure.

[0030] It should be noted that similar reference numerals and letters represent similar items in the following figures, so once an item is defined in one figure, it does not need to be further defined or explained in subsequent figures.

[0031] It should be noted that in the description of the embodiments of the present disclosure, the terms "first" and "second" are used for distinguishing purposes only and cannot be understood as indicating or implying relative importance.

[0032] As shown in FIG. 1, the embodiment of the present disclosure provides a vehicle lamp module 100, including a side light source, and a reflector kit and a lens 104 arranged in sequence in a light path transmission direction. The reflector kit includes a first reflector 103 and a second reflector 105. The first reflector 103 and the second reflector 105 are arranged relative to each other in a first direction F1 perpendicular to a main optical axis direction A. A side light source is arranged corresponding to the first reflector 103. After the light emitted by the side light source is reflected by the first reflector 103 and the second reflector 105 in sequence, it is refracted and emitted through the lens 104 to form a light-emitting light pattern.

[0033] Further, the lens 104 includes at least one of a plano-convex lens, a biconvex lens, or a concave-convex lens, and at least one of the light-entering surface and the light-emitting surface of the lens 104 is a convex surface to achieve the effect of converging light.

[0034] The reflector kit includes a first reflector 103 and a second reflector 105, among them the first reflector 103 is a low-beam reflector 103b and / or a high-beam reflector 103a for realizing low beam illumination and / or high beam illumination; the reflector kit and the lens 104 are sequentially arranged along the main optical axis, and the first reflector 103 and the second reflector 105 in the reflector kit are arranged relative to each other in the first direction F1. In other words, the first reflector 103 and the second reflector 105 are arranged side by side in the first direction F1 and light can be reflected by the first reflector 103 toward the second reflector 105. It should be noted that the main optical axis refers to the axis in the front-rear direction of the vehicle lamp module 100 that passes through a point at which parallel lights converge after passing through the lens 104.

[0035] The main optical axis direction A is the front-rear direction of the vehicle lamp module 100, and the first direction F1 is the up-down direction of the vehicle lamp module 100. In the present disclosure, the first reflector 103 and the second reflector 105 are arranged side by side in the first direction F1, which is equivalent to arranging the first reflector 103 and the second reflector 105 in the up-down direction of the vehicle lamp module 100. In this way, the dimension of the entire vehicle lamp module 100 in the front-rear direction is shortened.

[0036] The side light source is arranged corresponding to the first reflector 103. The light emitted by the side light source enters the first reflector 103 and is reflected by the first reflector 103 toward the second reflector 105, and is reflected again by the second reflector 105. Finally, it passes through the light-entering surface and the light-emitting surface of the lens 104 for two refractions before being emitted, thus forming the light-emitting light pattern desired.

[0037] In summary, the vehicle lamp module 100 provided in the embodiment of the present disclosure has a reflector kit and a lens 104 arranged in sequence in a main optical axis direction A, and the main optical axis direction A is a front-rear direction of the vehicle lamp module 100. The reflector kit includes a first reflector 103 and a second reflector 105, and the first reflector 103 and the second reflector 105 are arranged relative to each other in a first direction F1, and the first direction F1 is an up-down direction of the vehicle lamp module 100. The side light source is arranged corresponding to the first reflector 103. The light emitted by the side light source is reflected by the first reflector 103 and then directed to the second reflector 105. After being reflected again by the second reflector 105, it is finally refracted by the lens 104 and then emitted to form a light-emitting light pattern. The vehicle lamp module 100 provided in the embodiment of the present disclosure has a reflector kit and a lens 104 that are arranged in the front-rear direction of the vehicle lamp module 100, and the first reflector 103 and the second reflector 105 in the reflector kit are arranged in the up-down direction of the vehicle lamp module 100, which reduces the dimension of the vehicle lamp module100 in the front-rear direction so that the vehicle lamp module 100 arrangement can be flattened.

[0038] Further, as shown in FIGS. 1 and 2, two reflector kits are provided, with each arranged on the upper and lower sides of the main optical axis, respectively. The second reflectors 105 of the two reflector kits are arranged close to the main optical axis, and the first reflectors 103 of the two reflector kits are arranged away from the main optical axis; the light emitted by the side light source 102a1 passes through the corresponding first reflector 103 and second reflector 105 in sequence, and then is refracted and emitted by the lens 104 to form a light-emitting light pattern.

[0039] The reflector kits are respectively arranged on the upper and lower sides of the main optical axis, and side light sources 102a1 are respectively arranged corresponding to the first reflector 103 of each reflector kit. The two reflector kits share a lens 104. The light emitted by the side light source 102a1 is directed to the corresponding first reflector 103, reflected by the first reflector 103 and then directed to the second reflector 105, reflected by the second reflector 105 and directed to the lens 104, and refracted by the lens 104 and emitted to form a light-emitting light pattern.

[0040] Further, the second reflectors 105 of the two reflector kits have an angle and are integrally molded. As shown in FIG. 3, two first reflectors 103 and two second reflectors 105 are symmetrically arranged on the upper and lower sides of the main optical axis, in which an angle is formed between the two symmetrically arranged second reflectors 105 and they are integrally molded. In this way, the light emitted by the upper and lower side light sources 102a1 is respectively directed to the lens 104 after passing through the first reflector 103 and the second reflector 105 on the corresponding sides in sequence, and is refracted by the lens 104 before being emitted. The upper and lower second reflectors 105 form an angle and are arranged as a whole, which simplifies the module structure and facilitates mounting, and can also ensure the desired light-emitting light pattern.

[0041] When the surface shape of the lens 104 is different, the light pattern formed by the two refractions of the lens 104 is different. The light-entering surface of the lens 104 can be a plane or a curved surface. In one implementation method of the present disclosure, the light-entering surface of the lens 104 is a plane and the light-emitting surface is a curved surface. When the light emitted by the side light source 102a1 is emitted through the light-emitting surface of the lens 104, the curvature of the light-emitting surface is large, and the light is deflected at a large angle before being emitted.

[0042] As shown in FIG. 2, taking the first reflector 103 arranged above the main optical axis as a high-beam reflector 103a and the first reflector 103 arranged below the main optical axis as a low-beam reflector 103b as an example, the light emitted by the upper side light source 102a1 is reflected by the low-beam reflector 103a and then reflected to the light-entering surface of the lens 104 by the corresponding second reflector 105, and refracted once through the light-entering surface of the lens 104. The light is then refracted once by the light-emitting surface of lens 104. When the light is emitted from the lens 104, most of the light is emitted from the upper part of the lens 104 and converges to the main optical axis. Some of the light is deflected at a large angle, emitted from the lower part of the lens 104, and extends below the main optical axis. The light emitted from the side light source 102a1 below is reflected by the high-beam reflector 103b and then passes through the corresponding second reflector 105 to the light-entering surface of the lens 104, where it is refracted once by the light-entering surface of the lens 104 and then refracted once by the light-emitting surface of the lens 104. When the light is emitted from the lens 104, most of the light is emitted from the lower part of the lens 104 and converges toward the main optical axis, and some of the light is deflected at a large angle, emitted from the upper part of the lens 104, and extends above the main optical axis. The high beam light and the low beam light occupy more than half of the lens 104. Therefore, compared with the configuration in which the high beam light path and the low beam light path are each provided with a respective lens, sharing the same lens 104 for both the high beam light path and low beam light path can reduce the up-down dimension of the lens light-entering surface and reduce the size of the lens. Such a setting method can make more use of the lens 104. The more the lens 104 is used, the higher the brightness of the low beam / high beam light emitted.

[0043] In this implementation method, the focus F formed by the second reflector 105 and the lens 104 is identified in such a way that, as shown in FIG. 3, external parallel light is incident from the light-emitting surface of the lens 104, reaches the second reflector 105 through the light-entering surface of the lens 104 in turn, and then reflects toward the first reflector 103. The focus F is focused to a point near the first reflector 103. It can be seen that the light path of the focus F is opposite to the light path of the light pattern formed by a normal light source. Thus, the focus F and the position of each element can be identified to obtain a clear image.

[0044] In another implementation method of the present disclosure, as shown in FIGS. 4, 5, and 6, the light-entering surface of the lens 104 includes two interconnected incident regions 104a. The two incident regions 104a are configured to transmit light emitted through two reflector kits, respectively. Each incident region 104a of the lens 104 corresponds to an exit region. After the light emitted by the side light source 102a1 enters the lens 104 from the corresponding incident region 104a, it is emitted from the corresponding exit region to form a corresponding light-emitting light pattern.

[0045] For example, the two incident regions 104a are both planes and connected to each other to form the light-entering surface of the lens 104. As shown in FIG. 6, an angle is formed between the two incident regions 104a. The light-emitting surface of the lens 104 is a convex surface, which is divided into two exit regions corresponding to the incident region 104a. The light emitted by the side light source 102al is reflected by the first reflector 103 and then enters the second reflector 105. After being reflected again by the second reflector 105, it enters the lens 104 and is refracted by the lens 104 before exiting. The light close to the main optical axis is deflected at a large angle and converges with the light away from the main optical axis, as shown in FIG. 7.

[0046] Further, the two incident regions 104a are arranged obliquely relative to a vertical plane, and compared with the method of being arranged in parallel in a vertical direction, the thickness of the lens 104 can be reduced, so that the lens 104 in the implementation method of the present disclosure is a thin lens.

[0047] On this basis, a light shield 107 is further provided on a light-entering side of the lens 104, and the light shield 107 is located between the two incident regions 104a to separate the two incident regions 104a of the lens 104, prevent the light emitted by the side light source 102al from crossing when it does not enter the corresponding incident region 104a, and avoid the formation of stray light.

[0048] The identification method of its focus F is shown in FIG. 8, which is consistent with the preceding implementation method. External parallel light is incident from two exit regions of the lens 104 respectively, forming a focus F near the first reflector 103.

[0049] The vehicle lamp module 100 further includes a radiator 101, a circuit board 102, and a lens bracket 106. Among them, the light source and the reflector kit are arranged on one side of the circuit board 102, the radiator 101 is arranged on the other side of the circuit board 102, the lens 104 is fixed to the lens bracket 106, and the lens bracket 106 is fixedly connected to the reflector kit.

[0050] During mounting, as shown in FIG. 5, the vehicle lamp module 100 is fixed by screws passing through the radiator 101, the circuit board 102, the reflector kit, and the lens bracket 106 in sequence.

[0051] In another implementation method of the present disclosure, a third light path is included; specifically, as shown in FIGS. 9, 10, and 11, the vehicle lamp module 100 further includes a central light source, a gap is kept between the second reflectors 105 of the two reflector kits, the central light source 102a0 is arranged corresponding to the gap, and the light emitted by the central light source 102a0 enters the lens 104 through the gap and then exits.

[0052] Similar to the preceding mounting method, the implementation method is as shown in FIG. 10, in which the vehicle lamp module 100 is fixed by screws passing through the radiator 101, the circuit board 102, the reflector kit, and the lens bracket 106 in sequence. In order to make the mounting more stable, more screws can be used for fixing during mounting. Naturally, the mounting method is not limited to the above one and can be set as needed.

[0053] As shown in FIG. 11, the central light source 102a0 is located between the side light sources 102a1 on both sides of the main optical axis, and emits light to the gap between the second reflectors 105 on the upper and lower sides of the main optical axis. The light emitted by the central light source 102a0 directly enters the lens 104 and is refracted twice by the lens 104 before being emitted.

[0054] Further, a third reflector kit 108 is further provided, and the third reflector kit 108 includes a plurality of sub-reflectors 108a symmetrically arranged about the central light source 102a0. Some of the light emitted by the central light source 102a0 is reflected by the sub-reflectors 108a after passing through the gap towards the lens 104 and then exits.

[0055] A plurality of sub-reflectors 108a are symmetrically arranged about the central light source 102a0, and an angle is formed between the symmetrical sub-reflectors 108. Some of the light emitted by the central light source 102a0 reaches the sub-reflectors 108a, and after being reflected by the sub-reflectors 108a, it reaches the lens 104 and then exits.

[0056] In one achievable implementation method, the sub-reflector 108a and the second reflector 105 on the corresponding side have an angle and are integrally molded. For example, the sub-reflector 108a located on the upper side of the main optical axis and the second reflector 105 on the upper side form an angle and are integrally molded. The same is true for the sub-reflector 108a and the second reflector 105 on the lower side of the main optical axis, which facilitates the compact layout of the module structure and mounting, and does not affect the transmission on their respective light paths.

[0057] Correspondingly, the lens 104 includes a central region 104b located in the center and side regions 104c located on both sides of the central region 104b, and the three are connected in sequence. The light emitted by the central light source 102a0 is emitted from the central region 104b of the lens 104, and the light emitted by the side light source 102a1 is reflected by the reflector kit and then emitted from the side region 104c of the lens 104.

[0058] The lens 104 is a thin lens, and the lens 104 forms three sequentially connected regions, namely the central region 104b and two side regions 104c, to emit three paths of light. In the longitudinal direction, the light-entering surface of the central region 104b forms an angle with the light-entering surfaces of the two side regions 104c. For example, the light-entering surface of the side region 104c is a plane and the light-emitting surface thereof is a convex surface, and the two side regions 104c are symmetrically arranged along the main optical axis. The light converges and emerges after passing through the light-entering surface of the side region 104c and the light-emitting surface of the side region 104c; the light-entering surface of the central region 104b is a convex surface and the light-emitting surface thereof is a plane. The light emits after passing through the light-entering surface of the central region 104b and the light-emitting surface of the central region 104b. Naturally, the light-entering surface of the side region 104c can further be a convex surface and the light-emitting surface thereof can be a plane; the light-entering surface of the central region 104b can further be a plane and the light-emitting surface thereof can be a plane or a curved surface. No restriction is set here. In general, the side region 104c serves as a light emitting lens for the high beam path and the low beam path of the vehicle lamp module 100, respectively, and the light path formed by the light passing through the central region 104b can be used as a part of the low beam path or the high beam path to realize the low beam or high beam function, or can be used as a signal light path or a part of signal light path to realize the signal light function.

[0059] The identification method of its focus F is shown in FIG. 12, which is consistent with the preceding implementation method. External parallel light is incident from three exit regions of the lens 104 respectively, thus forming a focus F near the first reflector 103.

[0060] The first reflector 103 includes a high-beam reflector 103a and / or a low-beam reflector 103b, the low-beam reflector 103b has a cutoff line structure 103b1 near the boundary of the light source, and the focus F formed by the second reflector 105 and the lens 104 is set at the boundary of the low-beam reflector 103b close to the light source or on the reflecting surface of the high-beam reflector 103a.

[0061] For example, the first reflector 103 above the main optical axis is a high-beam reflector 103a, and the first reflector 103 below the main optical axis is a low-beam reflector 103b. A cutoff line structure 103b1 is provided at the edge of the low-beam reflector 103b. By setting the focus F (the focus F formed by the second reflector 105 and the lens 104) at the edge of the low-beam reflector 103b, a low beam light pattern with a cutoff line (see FIG. 13) is realized. The high beam light pattern is realized by setting the focus F (the focus F formed by the second reflector 105 and the lens 104) on the reflecting surface of the high-beam reflector 103a. In other words, a high beam path is formed above the main optical axis, and a low beam path is formed below the main optical axis. The third light path located between the high beam path and the low beam path can be used as a low beam path or a part of the high beam path, or as a signal light path or a part of the signal light path.

[0062] Traditional projection vehicle lamp modules have a lens focal length of about 40 mm - 45 mm and a reflector focal length of 30 mm - 40 mm. Coupled with circuit boards, radiators, and other components, it is difficult for traditional projection vehicle lamp modules to control the front-rear dimension within 100 mm.

[0063] In the present disclosure, the focus F formed by the lens 104 and the second reflector 105 is mirror-symmetrical with the focus of the lens 104 (the focus formed by the dotted line in FIG. 12) about the centerline of the second reflector 105. In other words, after the focal length of the lens 104 is reflected upward or downward by the second reflector 105, the final focus F is formed in the vertical direction of the vehicle lamp module 100 close to the first reflector 103, thereby shortening the dimension of the vehicle lamp module 100 in the front-rear direction. The front-rear dimension can be 50 mm - 60 mm, which is conducive to the flattening arrangement of the vehicle lamp module 100.

[0064] In the implementation method of the above three light paths, taking FIG. 9 as an example, a plurality of reflector kits are arranged in the second direction F2, and the second direction F2 is perpendicular to the main optical axis direction A and the first direction F1, respectively. It should be noted that the second direction F2 is the left-right direction of the vehicle lamp module 100.

[0065] For example, as shown in FIGS. 13 and 14, four reflector kits are provided above the main optical axis, including four high-beam reflectors 103a and four second reflectors 105, and one high-beam reflector 103a corresponds to one second reflector 105; four reflector kits are provided below the main optical axis, including four low-beam reflectors 103b and four second reflectors 105, and one low-beam reflector 103b corresponds to one second reflector 105; and whether in the first direction F1 (up-down direction) or the second direction F2 (left-right direction), no matter how many reflector kits there are, each corresponds to only one lens 104, and the light emitted by all reflector kits is refracted twice by one lens 104 to form different light patterns.

[0066] The light-entering surface of the lens 104 includes at least one curved surface, and a light-emitting surface of the lens 104 includes at least one curved surface. When the light-entering surface of the lens 104 is a plane, the corresponding light-emitting surface is a curved surface; when the light-entering surface of the lens 104 is a curved surface, the corresponding light-emitting surface is a plane or a curved surface; when the light-entering surface of the lens 104 is divided into multiple incident regions 104a and when the incident region 104a is a plane, the corresponding exit region is a curved surface; when the incident region 104a is a curved surface, the corresponding exit region is a plane or a curved surface. Both of the above light paths meet the above requirements.

[0067] In the present disclosure, the second reflector 105 is a unidirectional collimating reflector, and the reflecting surface thereof has a converging effect on light in a certain direction. For example, the reflecting surface of the second reflector 105 is a stretching surface with a curve unidirectionally stretching in the third direction F3, and the third direction F3 is inclined and has an angle relative to the first direction F1. The second reflector 105 can collimate the light lighted on its reflecting surface in a direction perpendicular to the third direction F3.

[0068] In the present disclosure, the light-entering surface or the light-emitting surface of the lens 104 is a collimating surface, which has a converging effect on the incident light in a certain direction. For example, the light-entering surface or the light-emitting surface of the lens 104 is a stretching surface with a curve unidirectionally stretching in the second direction F2, collimating the light in the first direction F1, and the second direction F2 is perpendicular to the main optical axis direction A and the first direction F1, respectively.

[0069] As shown in FIGS. 15 and 16, the light-entering surface of the central region 104b and the light-emitting surface of the side region 104c of the lens 104 have a curve stretched unidirectionally in a normal direction of the plane where the curve is located, so as to achieve collimation of light in another direction (for example, if a curve is stretched in the first direction F1, namely, the up-down direction, then collimation in the second direction F2, namely, the left-right direction, can be achieved. Similarly, if a curve is stretched in the second direction F2, namely, the left-right direction, then, collimation is achieved in the first direction F1, namely, the up-down direction). Accordingly, the corresponding second reflector 105 can be regarded as stretching a curve in a different stretching direction from the light-entering surface of the central region 104b or the light-emitting surface of the side region 104c, so as to achieve unidirectional collimation of the light in another direction. Finally, the light emitted by the light source passes through the reflector kit and the lens 104 and emits at least two directions of collimated light to form a light-emitting light pattern that meets the needs.

[0070] In the longitudinal direction, an angle is formed between the light-entering surface of the lens 104 and the main optical axis, and / or an angle is formed between the second reflector 105 and the main optical axis.

[0071] For example, as shown in FIG. 16, in a longitudinal section of the vehicle lamp module 100, the light-entering surfaces of the two side regions 104c of the lens 104 are inclined relative to the main optical axis to form an angle; the reflecting surface of the second reflector 105 is inclined relative to the main optical axis to form an angle; if the angles are different, the positions of focus F of the second reflector 105 and the lens 104 are different. Therefore, by adjusting the angle, the positions of focus F of the second reflector 105 and the lens 104 can be adjusted. Specifically, the upper and lower positions of the focus F can be adjusted by adjusting the angle between the light-entering surface of the lens 104 and the main optical axis. By adjusting the angle between the reflecting surface of the second reflector 105 and the main optical axis, the mirror position of the focus F can be adjusted. It is also possible to adjust the angle between the light-entering surface of the lens 104 and the main optical axis, and in addition, the angle between the reflecting surface of the second reflector 105 and the main optical axis, so as to simultaneously achieve the adjustment of the upper and lower and mirror positions of the focus F, and then determine the final position of focus F.

[0072] In addition, when an angle is formed between the light-entering surface of the lens 104 and the main optical axis, and / or when an angle is formed between the second reflector 105 and the main optical axis, the lens 104 and the second reflector 105 can be thinned to facilitate injection molding of the lens 104 and the second reflector 105.

[0073] In addition, for a vehicle lamp module 100, if the vehicle lamp module 100 is a high beam module, the first reflector 103 is a high-beam reflector 103a; if the vehicle lamp module 100 is a low beam module, the first reflector 103 is a low-beam reflector 103b; and if the vehicle lamp module 100 is a high and low beam integrated module, some first reflectors 103 are high-beam reflectors 103a, and some other first reflectors 103 are low-beam reflectors 103b. For example, FIG. 11 illustrates a case where the vehicle lamp module 100 is a high and low beam integrated module, in which the first reflector 103 above the main optical axis is configured as the high-beam reflector 103a, and the first reflector 103b below the main optical axis is configured as the low-beam reflector 103b. Naturally, in one implementation method, the preceding reflector kit is symmetrically arranged in two rows along the main optical axis, and each row can be provided with multiple reflector kits. The vehicle lamp module 100 can realize high beam or low beam, and can also realize the integration of high beam and low beam. In addition, when the third light path is used as a signal light path, the reuse of high beam, low beam, and signal light can be realized to meet the multifunctional composite requirements of the vehicle lamp module 100.

[0074] Furthermore, the embodiments of the present disclosure further provide a vehicle lamp, including the preceding vehicle lamp module 100 arranged in the vehicle lamp, and the light emitted by the vehicle lamp module 100 is emitted from the light emitting side of the vehicle lamp to form a light pattern. The dimension of the vehicle lamp module 100 in the front-rear direction is small, allowing the vehicle lamp more front-rear space to configure other components, thereby improving the freedom of vehicle lamp design and user satisfaction.

[0075] For example, when the vehicle lamp is applied to an electric vehicle, the smaller the dimension of the vehicle lamp module 100 in the front-rear direction is, when the original engine bay position of the vehicle is changed to a trunk space, the larger the trunk space is, which can meet the user's needs for placing items.INDUSTRIAL APPLICABILITY

[0076] The dimension of the vehicle lamp module 100 in the front-rear direction is reduced, and when applied to a vehicle lamp, allows the vehicle lamp more front-rear space. When the vehicle lamp module 100 is applied to an electric vehicle, since the dimension of the vehicle lamp module 100 in the front-rear direction is reduced, when the original engine bay position of the vehicle is changed to a trunk space for use, the size of the trunk space is increased, so that a user's need to place items in the trunk can be met, which is convenient for the user to store more items when using it. The dimension change offers strong practicality and is suitable for promotion.
