Description

车灯照明模组及车灯Car lighting module and car lights 技术领域technical field
本发明涉及车灯,具体地,涉及一种车灯照明模组。本发明还涉及一种车灯。The invention relates to a vehicle lamp, in particular to a vehicle lamp lighting module. The invention also relates to a vehicle lamp.
背景技术Background technique
车灯照明模组按照其作用分为远光照明模组、近光照明模组和远近光一体照明模组,按照其光形形成原理又可以分为反射式照明模组和投射式照明模组。投射式照明模组通常由光源、类椭球面反射镜及准直透镜组成,具有近光照明功能的照明模组中,还需要在准直透镜的焦点附近设置遮光板,以形成具有明暗截止线(照明光形上边界)的近光照明光形。在远近光一体投射式照明模组中,通常需要通过执行机构对遮光板进行位置切换,以分别形成远、近光照明光形。Car light lighting modules can be divided into high-beam lighting modules, low-beam lighting modules, and high-beam integrated lighting modules according to their functions, and can be divided into reflective lighting modules and projective lighting modules according to their light shape formation principles. . A projected lighting module is usually composed of a light source, an ellipsoidal reflector, and a collimating lens. In a lighting module with a low-beam lighting function, it is also necessary to set a shading plate near the focus of the collimating lens to form a light-dark cut-off line. (Illumination light shape upper boundary) low beam lighting light shape. In the far and near beam integrated projection lighting module, it is usually necessary to switch the position of the shading plate through the actuator to form the far and near beam lighting shapes respectively.
自适应远光模组通常使用多个矩阵式排列的光源和与每个光源相对应的初级光学元件来形成多个照明光斑,多个照明光斑并列叠加形成远光照明光形。其中,每个光源的亮灭能够独立控制,这样,就可以通过各个光源的亮灭来控制对应的光斑区域的明暗,从而形成自适应远光照明。现有的自适应远光模组由于光路结构较为复杂,通常仅能实现远光照明功能,受光路排布的影响,难以与近光照明模组相结合,实现近光照明功能。在需要实现近光功能时,同样需要在光路中增加遮光板,通过执行机构对遮光板进行位置切换,来实现远、近光照明光形的切换。Adaptive high-beam modules usually use multiple light sources arranged in a matrix and primary optical elements corresponding to each light source to form multiple lighting spots, and multiple lighting spots are superimposed side by side to form a high-beam lighting shape. Wherein, the on and off of each light source can be independently controlled, so that the brightness and darkness of the corresponding spot area can be controlled through the on and off of each light source, thereby forming adaptive high beam lighting. Due to the complex structure of the optical path, the existing adaptive high-beam modules can only realize the high-beam lighting function. Due to the influence of the optical path arrangement, it is difficult to combine with the low-beam lighting module to realize the low-beam lighting function. When it is necessary to realize the low beam function, it is also necessary to add a shading plate in the optical path, and switch the position of the shading plate through the actuator to realize the switching of the far and low beam lighting shapes.
现有的车灯照明模组中,反射式照明模组的类椭球面反射镜的第二焦点设置在准直透镜的焦点区域;透射式照明模组的初级光学元件出光面设置在透镜焦点区域,在能够实现近光照明功能的模组中,遮光板也必须设置在准直透镜的焦点附近,这就导致设置在准直透镜的焦点区域的光学器件较多,不同初级光学单元及其形成的光路之间相互影响,限制了车灯照明模组中初级光学单元的位置和数量。而设置在准直透镜焦点附近的遮光板也容易对远光光路形成遮挡,影响远光照明区域的照明效果。在远近光一体照明模组中,需要通过机械结构进行遮光板位置的切换,不仅切换速度低,切换稳定性较差,而且切换噪音较大。In the existing lighting modules for vehicles, the second focal point of the quasi-ellipsoid reflector of the reflective lighting module is set in the focal area of the collimating lens; the light-emitting surface of the primary optical element of the transmissive lighting module is set in the focal area of the lens , in the module that can realize the low beam lighting function, the shading plate must also be set near the focus of the collimator lens, which leads to more optical devices set in the focus area of the collimator lens, different primary optical units and their formation The mutual influence between the light paths of the car lights limits the position and number of primary optical units in the lighting module of the car. The shading plate arranged near the focal point of the collimating lens also easily blocks the high-beam optical path, affecting the lighting effect of the high-beam lighting area. In the far and near light integrated lighting module, the position of the visor needs to be switched through a mechanical structure, which not only has a low switching speed, poor switching stability, but also high switching noise.

It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and the scope of protection of the present invention is not limited to the following specific embodiments. .
如图1至图21所示,本发明的车灯照明模组的一个实施例,包括初级光学单元1、双焦点光学元件2和准直光学元件3。初级光学单元1包括光源11和聚光元件12,聚光元件12是一种能够收集光源11发出的光线,并形成一定的光分布的光学元件。具体地,聚光元件12可以是具有抛物面反射面或者类抛物面反射面的抛物面反射镜,可以是具有椭球面反射面或者类椭球面反射面的椭球面反射镜,也可以是透明光导聚光件、凸透镜或透镜组,还可以是上述几种光学元件的可能的组合。类抛物面反射面是在抛物面反射面的基础上进行适应性调整所形成的与抛物面反射面功能类似的反射面,对抛物面反射面进行的调整能够调整局部反射面的反射方向,以调整反射后的光线所形成的光分布。双焦点光学元件2是一种具有第一焦点F1和第二焦点F2的光学元件,具体地,双焦点光学元件2可以是具有椭球面反射面或者类椭球面反射面的椭球面反射镜,也可以是凸透镜或者具有两个焦点的透镜组,也可以是其他可能的具有两个焦点的光学元件或者光学元件组。类椭球面反射面是指在椭球面反射面的基础上进行适应性调整,以调整其局部反射面的反射方向和所形成的光分布,所形成的与椭球面反射面功能类似的反射面。随着所使用的聚光元件12的种类的不同,光源11设置在聚光元件12的不同相对位置,使得聚光元件12能够收集光源11发出的光线。光源11优选使用LED发光芯片或者其它面光源,还可以为光源11配套设置散热器6,以降低光源11工作时的温度。光源11发出的光线经过不同种类的聚光元件12的折射和/或反射后,所形成的光分布的形式也不同。其中,椭球面反射镜、透明光导聚光件、凸透镜或透镜组能够将光源11发出的光线汇聚到双焦点光学元件2的第一焦点F1区域,在双焦点光学元件2的第一焦点F1区域形成初级光分布;抛物面反射镜能够对光源11发出的光线起到准直作用,形成平行射出初级光分布,投射向双焦点光学元件2。双焦点光学元件2能够将由聚光元件12汇聚到第一焦点F1区域的初级光分布,或者由聚光元件12投射来的初级光分布经过反射或者折射后,汇聚到双焦点光学元件2的第二焦点F2区域,形成为经过双焦点光学元件2转换的,位于双焦点光学元件2的第二焦点F2区域的次级光分布。双焦点光学元件2的第二焦点F2设置在准直光学元件3的焦点F区域,这样,次级光分布也就位于准直光学元件3的焦点F区域,准直光学元件3能够将焦点F区域的次级光分布放大后投射出去,形成清晰的照明光形。准直光学元件3可以是带有抛物面反射面或者类抛物面反射面的抛物面反射镜,也可以是凸透镜或透镜组。在准直光学元件3选用凸透镜或者透镜组时,凸透镜或者透镜组可以安装在透镜支架5上。 准直光学元件3的光轴是指准直光学元件3的对称轴,光线沿准直光学元件3的光轴射向准直光学元件3时,经过准直光学元件3的透射或者反射后,光线仍在原有的直线上传播。如准直光学元件3为抛物面反射镜,准直光学元件3的光轴是一条通过反射镜的焦点F,并垂直于抛物面反射镜的反射面曲率最大处切平面的直线;如准直光学元件3为凸透镜或透镜组,准直光学元件3的光轴是一条通过凸透镜或者透镜组两个焦点的直线。双焦点光学元件2的第二焦点F2设置在准直光学元件3的焦点F区域,也就是设置在准直光学元件3的光轴上,双焦点光学元件2的第一焦点F1可以设置在准直光学元件3的光轴上,也可以设置在准直光学元件3的光轴之外。由于双焦点光学元件能够将位于第一焦点F1区域的初级光分布转换到第二焦点区域形成次级光分布,这样,就可以将双焦点光学元件2和初级光学单元1设置在准直光学元件3的光轴之外,而使得初级光学单元1形成的光分布能够转换到第二焦点F2,也就是准直光学元件3的焦点F区域,从而不影响所形成的照明光形的清晰度。由于不再有传统车灯照明模组中的光源和初级光学元件必须设置在准直透镜光轴附近的限制,本发明的车灯照明模组中光学元件的设置更加灵活,在准直光学元件3的光轴之外的不同方位可以设置多个初级光学单元1和双焦点光学元件2,而不用担心不同的初级光学单元1、双焦点光学元件2及其附属结构之间的相互影响,或者对其他光学元件形成的光路造成干扰,提高了模组功能设置的灵活性。As shown in FIG. 1 to FIG. 21 , an embodiment of the vehicle lighting module of the present invention includes a primary optical unit 1 , a bifocal optical element 2 and a collimating optical element 3 . The primary optical unit 1 includes a light source 11 and a light concentrating element 12. The light concentrating element 12 is an optical element capable of collecting light emitted by the light source 11 and forming a certain light distribution. Specifically, the light concentrating element 12 can be a parabolic reflector with a parabolic reflective surface or a paraboloid-like reflective surface, can be an ellipsoidal reflector with an ellipsoidal reflective surface or a quasi-ellipsoidal reflective surface, or can be a transparent light-guiding concentrator , a convex lens or a lens group, or a possible combination of the above optical elements. Parabolic reflective surface is a reflective surface similar to parabolic reflective surface formed by adaptive adjustment on the basis of parabolic reflective surface. The adjustment of parabolic reflective surface can adjust the reflection direction of local reflective surface to adjust the reflective The light distribution formed by the light rays. The bifocal optical element 2 is an optical element with a first focal point F1 and a second focal point F2. Specifically, the bifocal optical element 2 can be an ellipsoidal mirror with an ellipsoidal reflective surface or a quasi-ellipsoidal reflective surface, or It may be a convex lens or a lens group with two focal points, or other possible optical elements or optical element groups with two focal points. The ellipsoidal reflective surface refers to the adaptive adjustment on the basis of the ellipsoidal reflective surface to adjust the reflection direction of the local reflective surface and the light distribution formed, and the formed reflective surface has a similar function to the ellipsoidal reflective surface. Depending on the type of light-condensing element 12 used, the light source 11 is arranged at different relative positions of the light-condensing element 12 , so that the light-condensing element 12 can collect the light emitted by the light source 11 . The light source 11 preferably uses LED light-emitting chips or other surface light sources, and a heat sink 6 can also be provided for the light source 11 to reduce the temperature of the light source 11 during operation. After the light emitted by the light source 11 is refracted and/or reflected by different types of light concentrating elements 12 , the forms of light distribution formed are also different. Wherein, the ellipsoid reflector, the transparent light guide concentrator, the convex lens or the lens group can converge the light emitted by the light source 11 to the first focal point F1 area of the bifocal optical element 2, and in the first focal point F1 area of the bifocal optical element 2 The primary light distribution is formed; the parabolic reflector can collimate the light emitted by the light source 11 to form a parallel primary light distribution and project it to the bifocal optical element 2 . The bifocal optical element 2 can converge the primary light distribution of the first focal point F1 region by the light concentrating element 12, or the primary light distribution projected by the light concentrating element 12 to the second focal point of the bifocal optical element 2 after reflection or refraction. The bifocal F2 area is formed as a secondary light distribution converted by the bifocal optical element 2 and located in the second focal point F2 area of the bifocal optical element 2 . The second focal point F2 of the bifocal optical element 2 is arranged on the focal point F area of the collimating optical element 3, like this, the secondary light distribution is just positioned at the focal point F area of the collimating optical element 3, and the collimating optical element 3 can focus F The secondary light distribution of the area is amplified and projected to form a clear lighting shape. The collimating optical element 3 may be a parabolic mirror with a parabolic reflective surface or a parabolic-like reflective surface, or a convex lens or a lens group. When the collimating optical element 3 is a convex lens or a lens group, the convex lens or lens group can be installed on the lens holder 5 . The optical axis of the collimating optical element 3 refers to the symmetry axis of the collimating optical element 3. When the light is directed toward the collimating optical element 3 along the optical axis of the collimating optical element 3, after being transmitted or reflected by the collimating optical element 3, The light still travels in the original straight line. If the collimating optical element 3 is a parabolic reflector, the optical axis of the collimating optical element 3 is a straight line passing through the focal point F of the reflector and perpendicular to the tangent plane at the maximum curvature of the reflective surface of the parabolic reflector; such as the collimating optical element 3 is a convex lens or a lens group, and the optical axis of the collimating optical element 3 is a straight line passing through the two focal points of the convex lens or lens group. The second focal point F2 of the bifocal optical element 2 is arranged on the focal point F area of the collimating optical element 3, that is, on the optical axis of the collimating optical element 3, and the first focal point F1 of the bifocal optical element 2 can be arranged on the collimating optical element 3. on the optical axis of the collimating optical element 3 or outside the optical axis of the collimating optical element 3 . Since the bifocal optical element can convert the primary light distribution located in the first focal point F1 area to the second focal point area to form a secondary light distribution, in this way, the bifocal optical element 2 and the primary optical unit 1 can be arranged in the collimating optical element 3, so that the light distribution formed by the primary optical unit 1 can be converted to the second focal point F2, that is, the focal point F area of the collimating optical element 3, so as not to affect the clarity of the formed illumination light shape. Since there is no longer the limitation that the light source and primary optical elements in the traditional car light lighting module must be arranged near the optical axis of the collimating lens, the arrangement of the optical elements in the car light lighting module of the present invention is more flexible. Multiple primary optical units 1 and bifocal optical elements 2 can be arranged in different orientations outside the optical axis of 3, without worrying about the mutual influence between different primary optical units 1, bifocal optical elements 2 and their auxiliary structures, or Interference with the optical path formed by other optical components improves the flexibility of module function setting.

The reflective surface of the parabolic mirror can be arranged in the first focal area of the bifocal optical element 2 .

When the light emitted by the light source 11 is irradiated on the parabolic reflector, the parabolic cut-off line structure 121 forms a reflection boundary of the light. In this way, after the light emitted by the light source 11 is reflected by the parabolic reflector, it is formed on one side of the formed light distribution. The cut-off line corresponding to the shape of the parabolic cut-off line structure 121 is converted by the bifocal optical element 2 and projected by the collimating optical unit 3 to form a low-beam illumination light shape with a clear cut-off line as shown in FIG. 6 .
在本发明的车灯照明模组的一些实施例中,如图9至图11所示,聚光元件12选用椭球面反射镜。光源11设置在椭球面反射镜的一个焦点区域,椭球面反射镜的另一个焦点设置在双焦点光学元件2的第一焦点F1区域。光源11发出的光线经过椭球面反射镜的反射后,汇聚到椭球面反射镜的另一个焦点区域,也就是双焦点光学元件2的第一焦点F1区域,形成初级光分布。In some embodiments of the vehicle lamp lighting module of the present invention, as shown in FIG. 9 to FIG. 11 , the light concentrating element 12 is an ellipsoid reflector. The light source 11 is set at one focus area of the ellipsoid reflector, and the other focus of the ellipsoid reflector is set at the first focus F1 area of the bifocal optical element 2 . After being reflected by the ellipsoid reflector, the light emitted by the light source 11 converges to another focal area of the ellipsoid reflector, that is, the first focal point F1 area of the bifocal optical element 2 to form a primary light distribution.

First focus F1 area. When the light emitted by the light source 11 is reflected by the light-collecting element 12 and then directed to another focal area of the ellipsoidal reflector, the shading plate 4 blocks the passing light, and is converted by the bifocal optical element 2 and collimated by the optical element 3 After the projection of , the low-beam illumination light shape with a cut-off line corresponding to the shape of the cut-off line structure 41 of the light-shielding plate is finally formed as shown in FIG. 6 . Compared with the traditional car lighting module, since the shading plate 4 is arranged in the first focal point F1 area of the bifocal optical element 2, the formed primary light distribution with cut-off line is transferred to the quasi-light through the bifocal optical element 2. The focus area of the straight optical element 3, and the first focal point F1 of the bifocal optical element 2 is usually set away from the optical axis of the collimating optical element 3, therefore, the shading plate 4 can be arranged at a position away from the optical axis of the collimating optical element 3, The flexibility of optical element setting is increased, and it will not interfere with other optical elements set in the module and the optical paths formed by them.

Specifically, at least two primary optical units 1 can be provided, and each primary optical unit 1 can include a light source 11 and a corresponding light-condensing element 12. The primary optical unit 1 includes a transparent light guide light concentrating member, and one or more light incident surfaces may be arranged on the transparent light guide light concentrator, and each light incident surface area is provided with one or more light sources 11, so that a primary optical unit 1 Multiple light sources 11 may be included. Each condensing element 12 can collect the light emitted by its corresponding light source 11, and can form a primary light distribution in the first focal point F1 area of the bifocal optical element 2. The primary light distribution is converted by the bifocal optical element 2 and collimated. After the projection of the optical element 3, an illumination light shape is formed. The plurality of primary optical units 1 can be all primary optical units for low beam, or all primary optical units for high beam, or some can be primary optical units for low beam, and some can be primary optical units for high beam. When there are multiple low-beam primary optical units in the vehicle lamp lighting module of the present invention, after the primary light distribution formed by each primary optical unit is converted by the bifocal optical element 2, the formed secondary light distribution is distributed in the collimation optical After the focal areas of the elements 3 are superimposed and/or combined, they are projected by the collimating optical element 3 to form a low-beam light shape. Because the shading plate in the traditional low beam module needs to be set in the focus area of the collimating optical element, all low beam light sources and low beam optical elements can only be set on the upper side of the shading plate, that is, the collimating optical element. Focus up side. In the vehicle lamp lighting module of the present invention, since the bifocal optical element 2 can convert the primary light distribution at different positions to the focus area of the collimating optical element 3, multiple low beam primary optical units can be arranged in the collimating optical element 3. Different positions outside the optical axis of the collimating optical element 3 can be arranged on the upper side of the optical axis of the collimating optical element 3 or on the lower side of the optical axis, so that more low beam primary optical systems can be arranged in a limited space . When there are multiple high-beam primary optical units in the vehicle light lighting module of the present invention, the primary light distribution formed by each multiple high-beam primary optics is converted by the bifocal optical element 2 and projected by the collimating optical element 3 , They can be superimposed and/or combined with each other to form a common high-beam lighting light shape, and can also be combined with each other to form a matrix-arranged lighting area set to realize the ADB high-beam function. In the vehicle light lighting module of the present invention, since both the light source 11 and the light-collecting element 12 can be arranged outside the optical axis of the collimating optical element 3, different positions around the optical axis of the collimating optical element 3 can be A plurality of light sources 11 and a plurality of light concentrating elements 12 are arranged without interfering with each other. When a structure such as a shading plate 4 is provided for forming a cut-off line, the structure is arranged on the optical path of each light-collecting element 12, so that it can be far away from the optical axis area of the collimating optical element 3, and avoids being used to form a cut-off line. The influence of the structure of the line on the optical path formed by other light sources 11 . Of course, in a car light lighting module provided with multiple primary optical units 1, one primary optical unit 1 can also be arranged on the optical axis of the collimating optical element 3, and other primary optical units 1 can be arranged on the optical axis of the collimating optical element 3. 3, mutual interference between different primary optical units 1 and their optical paths can also be avoided. In some embodiments of the vehicle lamp lighting module of the present invention, as shown in FIGS. 2 to 5, FIGS. The bifocal optical element, the low beam bifocal optical element and the high beam bifocal optical element can be set as independent optical elements, or can be connected together to form an integrated optical element. The light source 11 includes a low-beam light source and a high-beam light source, and there may be multiple low-beam light sources and high-beam light sources. The condensing element 12 includes a low-beam condensing element and a high-beam condensing element, and the low-beam condensing element and the high-beam condensing element can also have multiple, and each low-beam condensing element can correspond to one or more near-beam condensing elements As for the light source, each high-beam concentrating element may also correspond to one or more high-beam light sources. Among them, the high-beam light source and the high-beam concentrating element constitute the high-beam primary optical unit, the low-beam light source and the low-beam concentrating element constitute the low-beam primary optical unit, and the low-beam primary optical unit also includes a shading plate 4, or a low-beam primary optical unit. A cut-off line structure is arranged on the light concentrating element. The light emitted by the low-beam light source is converged or collimated by the low-beam concentrating element, and is blocked by the shading plate 4 or the cut-off line structure on the low-beam concentrating element, forming a low-beam primary light distribution with a light and dark cut-off line, The low-beam bifocal optical element can convert the low-beam primary light distribution to the second focus area, that is, the focal point F area of the collimating optical element 3, to form the low-beam secondary light distribution, and the low-beam secondary light distribution is formed by the collimating optical element 3 The level light distribution is amplified and projected out, forming a low-beam light shape with a cut-off line as shown in Figure 6. The light emitted by the high-beam light source is converged or collimated by the high-beam concentrating element to form the high-beam primary light distribution. The high-beam bifocal optical element can convert the high-beam primary light distribution to the second focus area, that is, collimation optics The focal point F area of the element 3 forms the secondary light distribution of the high beam, and the secondary light distribution of the high beam is amplified by the collimating optical element 3 and then projected to form the high beam light shape as shown in FIG. 7 . At this time, the vehicle lamp lighting module of the present invention forms a vehicle lamp lighting module integrating far and near beams. In this module, when the low beam light source and the high beam light source emit light at the same time, the low beam light shape and the high beam light shape are combined to form the high and low beam combined light shape as shown in Figure 8. By controlling the on and off of different light sources 11, the lighting light shape formed by the vehicle lamp lighting module of the present invention can also be conveniently switched among the low beam light shape, the high beam light shape and the high and low beam combination light shape. In the vehicle lamp lighting module of the present invention, due to the setting of the bifocal optical element 2, both the low beam primary optical unit and the high beam primary optical unit can be arranged in the optical axis area away from the collimating optical element 3, avoiding the low beam Mutual interference between the primary optics unit and the high beam primary optics unit. When there is a shading plate 4, since the shading plate 4 is also arranged in an area away from the focal point F of the collimating optical element 3, it can avoid that the light shading plate 4 blocks the light path of the high beam caused by the combination of the high and low beams. The combination of light, light and shape forms an illuminated dark area, which improves the driver's visual experience. A plurality of bifocal optical elements 2 can also be provided. When the number of bifocal optical elements 2 is more than two, a plurality of bifocal optical elements 2 are usually arranged in a matrix. Specifically, a plurality of bifocal optical elements 2 can be arranged along the The rotation matrix arrangement of a certain rotation axis may also be arranged in a linear matrix along a certain direction, and may also be partially arranged along a rotation matrix of a certain rotation axis and partially arranged in a linear matrix along a certain direction.

A plurality of primary optical units 1 can be arranged toward the bifocal optical unit 2 along a rotation matrix of a certain rotation axis, or can be arranged in a linear matrix along a certain direction, or can be arranged partly along a rotation matrix of a certain rotation axis, and partly along a certain rotation axis. A linear matrix arrangement in one direction. Since the bifocal optical element 2 can also be arranged outside the optical axis of the collimating optical element 3, a plurality of bifocal optical elements 2 can also be arranged without interfering with each other around the optical axis of the collimating optical element 3, further improving the light source 11. and the setting flexibility of the light concentrating element 12, and enable the primary light distribution formed by each light source 11 to be located in the first focal point F1 area of the bifocal optical element 2, improving the secondary light distribution converted by the bifocal optical element 2 clarity. Similarly, one of the multiple bifocal optical elements 2 can also be arranged on the optical axis of the collimating optical element 3, and the other bifocal optical elements 2 are arranged outside the optical axis of the collimating optical element 3, which can also avoid Mutual interference between different bifocal optical elements 2 , corresponding primary optical units 1 and their beam paths. The primary light distribution formed by a plurality of primary optical units 1 is converted by a plurality of bifocal optical elements 2, and then projected by a collimator optical element 3, which can not only form multiple illumination areas in the illumination light shape, but also form multiple Different types of lighting light shapes, such as low beam lighting light shape, high beam lighting relationship light shape, low beam widening lighting light shape, ADB high beam lighting light shape, etc. Different types of lighting light shapes can also be combined with each other to meet the lighting needs of vehicles in different states.
在本发明的车灯照明模组的一些实施例中,如图1至图5、图9至15和图21所示,双焦点光学元件2选用带有椭球面形反射面或类椭球面形反射面的双焦点反射镜。椭球面形反射面或类椭球面形反射面均具有两个焦点,从一个焦点区域发出的光线经过椭球面形反射面或类椭球面形反射面反射后,均能够汇聚到另一个焦点区域,因而可以将一个焦点区域的光线汇聚到另一个焦点区域,在另一个焦点区域形成光分布。可以将其中的任一个焦点作为第一焦点F1,另一个焦点作为第二焦点F2,完成光源11发出的光线从第一焦点F1至第二焦点F2的转换。In some embodiments of the vehicle lamp lighting module of the present invention, as shown in Figures 1 to 5, Figures 9 to 15 and Figure 21, the bifocal optical element 2 is selected to have an ellipsoidal reflective surface or a quasi-ellipsoidal surface Bifocal mirrors for reflective surfaces. Both the ellipsoidal reflective surface or the quasi-ellipsoidal reflective surface have two focal points, and the light emitted from one focus area can be converged to the other focal area after being reflected by the ellipsoidal reflective surface or the quasi-ellipsoidal reflective surface. Therefore, light from one focal area can be converged to another focal area to form a light distribution in the other focal area. Any one of the focal points can be used as the first focal point F1, and the other focal point can be used as the second focal point F2 to complete the conversion of the light emitted by the light source 11 from the first focal point F1 to the second focal point F2.
在本发明的车灯照明模组的一些实施例中,如图16至图20所示,双焦点光学元件2选用凸透镜或者透镜组。在凸透镜或者透镜组的两侧均具有一个焦点,使得凸透镜或者透镜组均具有两个焦点,从一个焦点区域发出的光线经过凸透镜或者透镜组的折射后,均能 够汇聚到另一个焦点区域。从而可以将一个焦点区域的光线汇聚到另一个焦点区域,在另一个焦点区域形成光分布。可以将其中的任一个焦点作为第一焦点F1,另一个焦点作为第二焦点F2,完成光源11发出的光线从第一焦点F1至第二焦点F2的转换。但在使用单个凸透镜作为双焦点光学元件2时,由于经过凸透镜折射的光线总体沿凸透镜的光轴方向传播,限制了双焦点光学元件2的第一焦点F1偏离准直光学元件3的光轴的距离,对模组设置的灵活性的提高形成了一定的影响。In some embodiments of the vehicle lighting module of the present invention, as shown in FIG. 16 to FIG. 20 , the bifocal optical element 2 is a convex lens or a lens group. There is a focal point on both sides of the convex lens or lens group, so that the convex lens or lens group has two focal points, and the light emitted from one focal area can be converged to the other focal area after being refracted by the convex lens or lens group. In this way, light from one focus area can be converged to another focus area, and a light distribution can be formed on the other focus area. Any one of the focal points can be used as the first focal point F1, and the other focal point can be used as the second focal point F2 to complete the conversion of the light emitted by the light source 11 from the first focal point F1 to the second focal point F2. But when using a single convex lens as the bifocal optical element 2, because the rays refracted by the convex lens generally propagate along the optical axis direction of the convex lens, the deviation of the first focal point F1 of the bifocal optical element 2 from the optical axis of the collimating optical element 3 is limited. The distance has a certain impact on the improvement of the flexibility of module settings.
本发明所提供的车灯照明模组,能够通过初级光学单元1形成初级光分布,并通过双焦点光学元件2将初级光分布转换到第二焦点F2区域,也就是准直光学元件3的焦点F区域,形成次级光分布,再经由准直光学元件3将次级光分布投射出去,形成照明光形。由于双焦点光学元件2的第二焦点F2设置在准直光学元件3的焦点区域,也就是在准直光学元件3的光轴上,而双焦点光学元件2的第一焦点F1设置在准直光学元件3的光轴之外,这就使得初级光学单元1和双焦点光学元件2可以设置在准直光学元件3的光轴之外的情况下,能够在准直光学元件3的焦点F区域形成光分布,保证经过准直光学元件3投射后形成的照明光形的位置和清晰度。与传统车灯照明模组中初级光学单元需要设置在准直光学元件的光轴附近不同,本发明的车灯照明模组中的初级光学单元1和双焦点光学元件2均可以设置在准直光学元件3的光轴周边远离光轴的位置,因而可以根据车灯的不同设计要求自由设置初级光学单元1和双焦点光学元件2的位置,提高了初级光学单元1和双焦点光学元件2的设置灵活性。在本发明的车灯照明模组中,初级光学单元1及其形成的初级光分布均可以设置在远离准直光学元件3光轴的位置,避免了不同初级光学单元1之间的影响,在初级光学单元1中设置有遮光板4时,遮光板4设置在对应的聚光元件12与双焦点光学元件2之间,不会对其他初级光学单元1或者双焦点光学元件2形成干扰,提高了截止线结构设置的自由度。在本发明的车灯照明模组的优选实施例中,在准直光学元件3的光轴周边的不同位置设置有多个不同的光源11、聚光元件12和双焦点光学元件2,每个光源11、聚光元件12和双焦点光学元件2能够形成一种照明光形,或者形成照明光形的一部分,丰富了本发明的车灯照明模组的功能,避免了不同的光源11、聚光元件12和双焦点光学元件2之间的相互影响。本发明的车灯照明模组,对模组中光学单元位置的限制更小,结构设置更加灵活,使得车灯照明模组能够根据设计要求布置空间占用,能够实现更多的照明光形,且能够更方便有效地进行不同光形的切换。The vehicle lamp lighting module provided by the present invention can form the primary light distribution through the primary optical unit 1, and convert the primary light distribution to the second focal point F2 area, which is the focal point of the collimating optical element 3, through the bifocal optical element 2.

Setup flexibility. In the vehicle lamp lighting module of the present invention, the primary optical unit 1 and the primary light distribution formed by it can be arranged at a position away from the optical axis of the collimating optical element 3, avoiding the influence between different primary optical units 1, and When the primary optical unit 1 is provided with a shading plate 4, the shading plate 4 is arranged between the corresponding light-gathering element 12 and the bifocal optical element 2, and will not interfere with other primary optical units 1 or bifocal optical elements 2, thereby improving The degree of freedom of the cut-off line structure setting is increased. In a preferred embodiment of the vehicle light lighting module of the present invention, a plurality of different light sources 11, condensing elements 12 and bifocal optical elements 2 are arranged at different positions around the optical axis of the collimating optical element 3, each The light source 11, the light concentrating element 12 and the bifocal optical element 2 can form an illumination light shape, or form a part of the illumination light shape, which enriches the functions of the vehicle light lighting module of the present invention and avoids different light sources 11, focus Interaction between light element 12 and bifocal optical element 2 . The car light lighting module of the present invention has less restrictions on the position of the optical unit in the module, and more flexible structural settings, so that the car light lighting module can be arranged according to the design requirements and occupy more space, and can realize more lighting light shapes, and It is more convenient and effective to switch between different light shapes.
