技术领域Technical field
本发明涉及车灯，具体地，涉及一种多像素远光系统。此外，本发明还涉及一种车灯及车辆。The invention relates to a vehicle lamp, in particular to a multi-pixel high beam system. In addition, the present invention also relates to a vehicle lamp and a vehicle.
背景技术Background technique
车辆的智能化系统越来越普及，目前应用最多的是多像素智能化远光功能，它可以实现在防止其它车辆眩目的前提下，最大限度的保证驾驶员的驾驶视野，提高车辆驾驶的安全性和舒适性。目前主要有两种形式来实现可关断的多像素远光：反射式和投射式。和反射式系统相比，投射式系统需要增加透镜等投射元件，在成本上比反射式高出不少；而反射式系统由于由反射镜构成，在成本上有一定优势。The intelligent system of vehicles is becoming more and more popular. At present, the most widely used is the multi-pixel intelligent high beam function, which can ensure the driver's driving vision to the greatest extent while preventing other vehicles from being dazzled, and improve the safety of driving. Sex and comfort. At present, there are mainly two forms to realize the multi-pixel high beam that can be turned off: reflective and projective. Compared with the reflective system, the projection system needs to add projection elements such as lenses, which is much higher in cost than the reflective system; and the reflective system has certain advantages in cost because it is composed of mirrors.
另外，随着多像素智能远光技术的不断发展，多像素智能化远光系统需要满足新的需求，多像素的智能远光对于单个像素的宽度可以根据车辆行驶道路上实际情况单独设定，在车道正前方附近区域需要形成分辨率高的暗区，单个像素宽度要窄，以使所形成暗区的宽度控制更精确，与车辆或行人所在区域的宽度相吻合，在防止对方炫目的同时也能保证本车驾驶员的视野；而在车道前方两侧区域车辆或行人较少，不需要形成分辨率很高的暗区，单个像素宽度可加宽，使得远光光形的多个像素的宽度由外向内形成一个由宽变窄的递变趋势。In addition, with the continuous development of multi-pixel intelligent high-beam technology, multi-pixel intelligent high-beam systems need to meet new requirements. The width of a single pixel of the multi-pixel intelligent high-beam can be set separately according to the actual conditions of the vehicle on the road. A high-resolution dark area needs to be formed in the area near the front of the lane. The width of a single pixel should be narrow, so that the width of the formed dark area can be controlled more accurately. It can also ensure the driver’s field of vision; while there are fewer vehicles or pedestrians in the areas on both sides of the lane in front of the lane, there is no need to form a high-resolution dark area, and the width of a single pixel can be widened to make multiple pixels in the high beam shape The width from the outside to the inside forms a gradual trend from wide to narrow.
目前的反射式多像素远光系统的一种结构是由多芯片的发光光源(芯片横向排布)以及反射镜组成。从发光光源发出的光线经过反射镜反射后，形成与发光芯片大小相对应的具有一定宽度的远光光形，其中像素的数量由芯片的数量决定，单个像素的宽度则由单个发光芯片和反射镜来共同决定，单个像素的宽度范围很小，导致不同像素的宽度相差不大。对于需要宽度差别很大的不同像素的情形，此种系统则无法满足上述需求。One structure of the current reflective multi-pixel high beam system is composed of multi-chip light-emitting light sources (the chips are arranged horizontally) and a reflector. The light emitted from the light-emitting source is reflected by the reflector to form a high-beam light shape with a certain width corresponding to the size of the light-emitting chip. The number of pixels is determined by the number of chips, and the width of a single pixel is determined by a single light-emitting chip and the reflector. The mirror determines that the width of a single pixel is very small, resulting in the same width of different pixels. For situations where different pixels with very different widths are required, this type of system cannot meet the above requirements.
申请日为2017年9月27日、公开号为CN107420825A的中国发明专利则公开了反射式多像素远光系统的另一种结构，其由反射镜和多颗LED光源组成，由于多颗LED光源共用一个反射镜，反射镜的焦点必然设置在中间位置的LED光源上，但若要形成与各LED光源一一对应的像素，需要其他LED光源尽可能靠近反射镜的焦点，而且所有LED光源对应一个反射镜，使得各LED光源对应形成的各个像素的宽度基本相同，无法单独的改变其中每个像素的宽度大小，因此仍然无法满足特定宽度的多像素组合要求。The Chinese invention patent with the application date of September 27, 2017 and the publication number CN107420825A discloses another structure of the reflective multi-pixel high beam system, which is composed of a reflector and multiple LED light sources. Sharing a mirror, the focal point of the mirror must be set on the LED light source in the middle position, but to form a one-to-one correspondence with each LED light source, other LED light sources need to be as close as possible to the focal point of the mirror, and all LED light sources correspond to A reflector makes the width of each pixel corresponding to each LED light source basically the same, and the width of each pixel in it cannot be changed separately, so it still cannot meet the requirement of multi-pixel combination with a specific width.

以下结合附图对本发明的具体实施方式进行详细说明。应当理解的是，此处所描述的具体实施方式仅用于说明和解释本发明，并不用于限制本发明。The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and are not used to limit the present invention.
本发明提供一种多像素远光系统，包括多个发光光源1、以及与所述发光光源1相配合的聚光元件和至少一个反射元件，其中，所述聚光元件形成有多个并列设置、具有设定宽度的聚光单元，各所述发光光源1分别与各所述聚光单元一一对应，以能够使各所述发光光源1发出的光线经所述聚光元件汇聚后、并经所述反射元件反射后形成多个光斑，所述多个光斑依次排列形成具有多个像素的光形，且各所述光斑的宽度与各所述聚光单元的设定宽度相对应。The present invention provides a multi-pixel high beam system, including a plurality of light-emitting light sources 1, and a light-concentrating element matched with the light-emitting light source 1 and at least one reflective element, wherein the light-concentrating element is formed with a plurality of parallel arrangement , A light-condensing unit with a set width, each of the light-emitting light sources 1 corresponds to each of the light-concentrating units, so that the light emitted by each of the light-emitting light sources 1 can be condensed by the light-concentrating element and combined After being reflected by the reflective element, a plurality of light spots are formed, and the plurality of light spots are arranged in sequence to form a light shape with a plurality of pixels, and the width of each light spot corresponds to the set width of each light collecting unit.
需要说明的是，如图13、图14所示的光形示意图，远光光形a的每一个格子代表一个像素，远光光形a是由多个光斑沿左右方向依次排列形成，如果各光斑恰好相互衔接，则像素的宽度与其对应光斑的宽度相同，但是，这种情况下，各像素之间会有明显的明暗分界线， 使得远光光形均匀性较差，因此，为了使各像素之间的衔接过渡均匀，各光斑之间会有部分叠加，此时，光斑的宽度应该大于与其对应像素的宽度。光斑的宽度与其对应的聚光单元的宽度对应，因此，为了实现如图13、图14所示的车辆正前方附近区域分辨率高、车辆前方的两侧区域分辨率低的光形，可通过设定各聚光单元的宽度来得到具有不同宽度的光斑，以形成具有多个特定宽度的像素的多像素远光光形。其中，车辆正前方附近区域的光形投射在配光屏幕上的所在区域为图13和图14所示的光形示意图中的光形中心区域(水平0度线和竖直0度线的交点所在区域)，车辆前方的两侧区域的光形投射在配光屏幕上的所在区域为图13和图14所示的光形示意图中的光形外侧区域。It should be noted that, as shown in the schematic diagrams of the light shape shown in Figures 13 and 14, each grid of the high beam light shape a represents a pixel, and the high beam light shape a is formed by multiple light spots arranged in the left and right directions. If the light spots are exactly connected to each other, the width of the pixel is the same as the width of the corresponding light spot. However, in this case, there will be an obvious light and dark boundary between each pixel, which makes the uniformity of the high beam light shape poor. Therefore, in order to make each The transition between the pixels is uniform, and there will be a partial overlap between the light spots. At this time, the width of the light spot should be greater than the width of the corresponding pixel. The width of the light spot corresponds to the width of the corresponding condensing unit. Therefore, in order to achieve a light shape with high resolution in the area near the front of the vehicle and low resolution in the areas on both sides of the front of the vehicle, as shown in Figures 13 and 14, The width of each condensing unit is set to obtain light spots with different widths to form a multi-pixel high beam light shape with a plurality of pixels with specific widths. Among them, the area where the light shape of the area near the front of the vehicle is projected on the light distribution screen is the light shape center area (the intersection of the horizontal 0 degree line and the vertical 0 degree line in the light shape diagrams shown in Figure 13 and Figure 14). Location), the area where the light shape of the areas on both sides of the front of the vehicle is projected on the light distribution screen is the area outside the light shape in the light shape schematic diagrams shown in FIGS. 13 and 14.
本发明的聚光元件形成多个并列设置、具有设定宽度的聚光单元，能够使各所述发光光源1发出的光线经聚光元件收集汇聚后、并经反射元件反射后形成具有多个特定宽度像素的远光光形，且通过设定聚光元件的各个聚光单元的宽度大小，能够形成具有与各个聚光单元宽度对应宽度的光斑，从而可以形成多个特定宽度的像素，使得每个像素的宽度大小可以调节，从而可以根据车辆行驶道路上的实际情况单独设定单个像素的宽度，满足多像素智能化照明需求。The concentrating element of the present invention forms a plurality of concentrating units arranged side by side with a set width, which can make the light emitted by each of the light-emitting light sources 1 be collected and condensed by the concentrating element, and then reflected by the reflective element to form a plurality of concentrating units. The high beam shape of pixels with a specific width, and by setting the width of each concentrating unit of the concentrating element, a light spot with a width corresponding to the width of each concentrating unit can be formed, so that a plurality of pixels with a specific width can be formed, so that The width of each pixel can be adjusted, so that the width of a single pixel can be individually set according to the actual situation of the vehicle on the road to meet the needs of multi-pixel intelligent lighting.
作为一种具体实施方式，如图1至图3所示，所述聚光元件为多腔反射器2，所述多腔反射器2包括多个并列设置、具有设定宽度的反射腔21，反射腔21即为上述聚光元件上的聚光单元。其中，所述反射元件的数量为两个，分别为第一反射器4和第二反射器3，所述第一反射器4设于所述多腔反射器2的正前方，所述第二反射器3位于所述多腔反射器2的下方，各所述发光光源1发出的光线经所述多腔反射器2收集汇聚后、并依次经所述第一反射器4和所述第二反射器3反射后形成具有多个像素的远光光形。通过设置第一反射器4和第二反射器3，使得发光光源1发出的光线经过多级反射能够更好地调节光线的入射和出射方向，从而更好地形成预期远光光形，且能使得本发明结构更加紧凑。As a specific implementation, as shown in FIGS. 1 to 3, the light-concentrating element is a multi-cavity reflector 2, and the multi-cavity reflector 2 includes a plurality of reflecting cavities 21 arranged in parallel and having a set width. The reflecting cavity 21 is the light-concentrating unit on the above-mentioned light-concentrating element. Wherein, the number of the reflecting elements is two, namely the first reflector 4 and the second reflector 3, the first reflector 4 is arranged directly in front of the multi-cavity reflector 2, and the second reflector The reflector 3 is located below the multi-cavity reflector 2, and the light emitted by each of the light-emitting light sources 1 is collected and converged by the multi-cavity reflector 2, and then passes through the first reflector 4 and the second reflector 4 in turn. The reflector 3 forms a high beam shape with a plurality of pixels after reflection. By arranging the first reflector 4 and the second reflector 3, the light emitted by the light-emitting source 1 can be better adjusted in the direction of incidence and exit through multi-stage reflection, thereby better forming the expected high beam light shape, and This makes the structure of the present invention more compact.
具体地，如图6至图8、图10至图12所示，各所述反射腔21的反射面均为抛物面，各所述发光光源1分别一一对应设在各所述反射腔21的焦点上，通过设置抛物面反射面，能够对发光光源1发出的大部分光线进行收集汇聚并反射至第一反射器4，能够提高光效。当然，各所述反射腔21的反射面也可以为弧形面、椭球面等曲面反射面，只要其能实现将发光光源1发出的光线进行收集汇聚并反射至第一反射器4，其同样属于本发明的保护范围。其中，由于各所述反射腔21为并列设置，为了防止相邻反射腔21之间发生窜光现象而形成杂散光，影响预期光形的形成，优选地，各相邻所述反射腔21之间设有将其相互隔开的隔筋22。Specifically, as shown in FIGS. 6 to 8 and 10 to 12, the reflecting surfaces of each of the reflecting cavities 21 are parabolic surfaces, and each of the light-emitting light sources 1 are respectively arranged in the reflecting cavity 21 in a one-to-one correspondence. At the focal point, by setting a parabolic reflecting surface, most of the light emitted by the light-emitting light source 1 can be collected, converged and reflected to the first reflector 4, which can improve the light efficiency. Of course, the reflecting surface of each reflecting cavity 21 may also be a curved surface such as an arc surface, an ellipsoidal surface, etc., as long as it can collect and converge the light emitted by the light-emitting source 1 and reflect it to the first reflector 4. It belongs to the protection scope of the present invention. Wherein, since the reflective cavities 21 are arranged side by side, in order to prevent the occurrence of stray light between adjacent reflective cavities 21 and affect the formation of the expected light shape, preferably, each of the adjacent reflective cavities 21 There are ribs 22 separating them from each other.
其中，多腔反射器2包括8个反射腔21，各个反射腔21的宽度大小可以根据实际配光和所需得到的光斑的宽度进行调整，由于在实际应用于车灯时，需要能够形成光形外侧区域的像素宽度宽(分辨率低)、位于光形中心区域的像素宽度窄(分辨率高)的远光光形，因此，当其应用于左车灯时，各反射腔21的宽度大小设置为从右到左与图13中各像素宽度大小从左向右一一对应，图13中a指的是具有8个像素的远光光形，b指的是近光光形，c指的是近光明暗截止线，图13中8个像素的宽度大小从左(光形外侧区域)向右(光形中心区域)逐渐减小，则理论上各反射腔21的宽度大小设置为从右向左也有逐渐减小的趋势，但是，为了像素之间的均匀衔接，使各光斑之间部分叠加，如图11所示的各反射腔21的宽度可根据其所需得到的光斑的宽度设定，并不一定有大小递变趋势，只要各光斑最终排列后能够得 到由光形外侧区域向光形中心区域像素宽度逐渐减小的光形即可；当其应用于右车灯时，各反射腔21的宽度大小设置为从右到左与图14中各像素宽度大小从左向右一一对应，图14中a指的是具有8个像素的远光光形，b指的是近光光形，c指的是近光明暗截止线，图14中8个像素的宽度大小从左(光形中心区域)向右(光形外侧区域)逐渐增大，则理论上各反射腔21的宽度大小设置为从右向左也有逐渐增大的趋势，但是同样，为了像素之间的均匀衔接，各反射腔21的宽度可根据其所需得到的光斑的宽度设定，并不一定有大小递变趋势，只要各光斑最终排列后能够得到由光形外侧区域向光形中心区域像素宽度逐渐减小的光形即可。由此，使得左右车灯的出射光形叠加后能够形成位于光形外侧区域的像素宽度宽(分辨率低)、光形中心区域的像素宽度窄(分辨率高)的远光光形。Among them, the multi-cavity reflector 2 includes 8 reflecting cavities 21, and the width of each reflecting cavity 21 can be adjusted according to the actual light distribution and the width of the light spot required. When it is actually applied to car lights, it needs to be able to form light. The pixel width of the outer area of the shape is wide (low resolution), and the pixel width in the center area of the light shape is narrow (high resolution). Therefore, when it is applied to the left car light, the width of each reflecting cavity 21 The size is set from right to left to correspond to the width of each pixel in Figure 13 from left to right. In Figure 13, a refers to the high-beam light shape with 8 pixels, b refers to the low-beam light shape, and c Refers to the near-bright-dark cut-off line. The width of the 8 pixels in Figure 13 gradually decreases from the left (the outer area of the light shape) to the right (the central area of the light shape), so theoretically the width of each reflective cavity 21 is set to There is also a tendency to gradually decrease from right to left. However, for the uniform connection between pixels, the light spots are partially overlapped. As shown in FIG. 11, the width of each reflecting cavity 21 can be based on the required light spot. The width setting does not necessarily have a trend of size gradual change, as long as the light spots are finally arranged to obtain a light shape whose pixel width gradually decreases from the outer area of the light shape to the center area of the light shape; when it is applied to the right car light , The width of each reflective cavity 21 is set from right to left to correspond to the width of each pixel in FIG. 14 from left to right. In FIG. 14, a refers to the high beam shape with 8 pixels, and b refers to It is the low-beam light shape, c refers to the near-bright and dark cut-off line. The width of the 8 pixels in Figure 14 gradually increases from the left (the central area of the light shape) to the right (the outer area of the light shape), and theoretically each reflection The width of the cavity 21 is set to gradually increase from right to left, but also, for the uniform connection between pixels, the width of each reflective cavity 21 can be set according to the width of the light spot that it needs, not There must be a gradual change in size, as long as the light spots are finally arranged to obtain a light shape whose pixel width gradually decreases from the outer area of the light shape to the center area of the light shape. As a result, the output light shapes of the left and right vehicle lights can be superimposed to form a high beam shape with a wide pixel width (low resolution) in the outer area of the light shape and a narrow pixel width (high resolution) in the center area of the light shape.
当然，多腔反射器2的多个反射腔21的宽度设置可以有不同的实现方式，均可以在左右车灯的出射光形叠加后形成位于光形外侧区域的像素宽度宽(分辨率低)、光形中心区域的像素宽度窄(分辨率高)的远光光形。参见图15至图17所示，图15是多腔反射器2应用于左车灯时的一种前视结构示意图(即多腔反射器2安装在左车灯时从车前向车内看时所呈现的视图结构)，其从左侧数的第一个反射腔21、第二个反射腔21、第三个反射腔21和第四个反射腔21的宽度相差不大，第五个反射腔21的宽度大于第四反射腔21的宽度，第六个反射腔21的宽度大于第五反射腔21的宽度，在配光屏幕上形成的整体出射光形具体如图18所示，图19至图24所示为各发光光源1发出的光线经与其对应的反射腔21反射并经反射元件反射后形成的对应光斑，由图中可以看出各光斑依次排列后会有部分重叠，且第一个反射腔21所对应形成的光斑、第二个反射腔21所对应形成的光斑、第三个反射腔21所对应形成的光斑、第四个反射腔21所对应形成的光斑的宽度相差不大，第五个反射腔21所对应形成的光斑的宽度大于第四个反射腔21所对应形成的光斑的宽度，第六个反射腔21所对应形成的光斑的宽度大于第五个反射腔21所对应形成的光斑的宽度，其与各反射腔21的宽度大小是一一对应的。如图25所示，关闭第二个、第四个和第六个反射腔21所对应的发光光源1所形成的光形示意图，可以看出第三个反射腔21所对应形成的光斑和第五个反射腔21所对应形成的光斑之间的暗区宽度即为第四个反射腔21所对应的像素宽度，其大于位于其右侧的第二个反射腔21所对应的像素宽度(即第一个反射腔21所对应形成的光斑和第三个反射腔21所对应形成的光斑之间的暗区宽度)；如图26所示，同理，第五个反射腔21所对应的像素宽度大于位于其右侧的第三个反射腔21所对应的像素宽度；结合图25和图26，可以看出，第五个反射腔21所对应的像素宽度大于位于其右侧的第四个反射腔21所对应的像素宽度，第四个反射腔21所对应的像素宽度大于位于其右侧的第三个反射腔21所对应的像素宽度，第三个反射腔21所对应的像素宽度与位于其右侧的第二个反射腔21所对应的像素宽度差不多，符合左车灯出射光形由光形外侧区域向光形中心区域像素宽度逐渐减小的特性。图16是多腔反射器2应用于右车灯时的一种前视结构示意图，其反射腔21的宽度的变化规律与上述图15所示的反射腔21的变化规律相反，在配光屏幕上形成像素宽度由光形外侧区域向光形中心区域逐渐减小的右车灯出射光形，左车灯出射光形和右车灯出射光形叠加后形成两侧像素宽度宽、中间像素宽度窄的远光光形。图17是多腔反射器2应用于左车灯和右车灯时的另一种前视结构示意图，应用于左车灯和右车灯的多腔反射器2结构相同，其反射腔21的宽度由两侧向中间逐渐减小，左右车灯的出射光形叠加后同样能够形成两侧像素宽度宽、中间像 素宽度窄的远光光形。Of course, the widths of the multiple reflecting cavities 21 of the multi-cavity reflector 2 can be implemented in different ways, all of which can form a wide pixel width (low resolution) in the area outside the light shape after the light shapes of the left and right car lights are superimposed. , High beam light shape with narrow pixel width (high resolution) in the center area of the light shape. Refer to Figures 15 to 17, which is a schematic diagram of a front view structure when the multi-cavity reflector 2 is applied to the left car lamp (that is, when the multi-cavity reflector 2 is installed in the left car lamp, it is viewed from the front of the car into the car The view structure presented at the time), the widths of the first reflective cavity 21, the second reflective cavity 21, the third reflective cavity 21 and the fourth reflective cavity 21 counted from the left are not much different, and the fifth one The width of the reflective cavity 21 is greater than the width of the fourth reflective cavity 21, and the width of the sixth reflective cavity 21 is greater than the width of the fifth reflective cavity 21. The overall shape of the emitted light formed on the light distribution screen is specifically shown in FIG. 18. Figures 19 to 24 show the corresponding light spots formed after the light emitted by each light-emitting light source 1 is reflected by its corresponding reflecting cavity 21 and reflected by the reflective element. It can be seen from the figure that the light spots will partially overlap after being arranged in sequence, and The light spot formed by the first reflective cavity 21, the light spot formed by the second reflective cavity 21, the light spot formed by the third reflective cavity 21, and the light spot formed by the fourth reflective cavity 21 are different in width Not big, the width of the light spot formed by the fifth reflective cavity 21 is greater than the width of the light spot formed by the fourth reflective cavity 21, and the width of the light spot formed by the sixth reflective cavity 21 is greater than that of the fifth reflective cavity The width of the light spot formed by 21 corresponds to the width of each reflecting cavity 21 in a one-to-one correspondence. As shown in FIG. 25, the schematic diagram of the light shape formed by the light-emitting light source 1 corresponding to the second, fourth, and sixth reflective cavity 21 is turned off. The width of the dark area between the light spots formed by the five reflective cavities 21 is the width of the pixel corresponding to the fourth reflective cavity 21, which is greater than the width of the pixel corresponding to the second reflective cavity 21 on the right side (ie The width of the dark area between the light spot corresponding to the first reflective cavity 21 and the light spot corresponding to the third reflective cavity 21); as shown in FIG. 26, the same is true for the pixel corresponding to the fifth reflective cavity 21 The width is greater than the width of the pixel corresponding to the third reflective cavity 21 located on the right side; in conjunction with Figures 25 and 26, it can be seen that the width of the pixel corresponding to the fifth reflective cavity 21 is greater than that of the fourth reflective cavity located on the right side The pixel width corresponding to the reflective cavity 21, the pixel width corresponding to the fourth reflective cavity 21 is greater than the pixel width corresponding to the third reflective cavity 21 on the right side, and the pixel width corresponding to the third reflective cavity 21 is equal to The pixel width corresponding to the second reflecting cavity 21 located on the right side is almost the same, which conforms to the characteristic that the pixel width of the left car light emitting light shape gradually decreases from the outer area of the light shape to the center area of the light shape. 16 is a schematic diagram of a front view structure when the multi-cavity reflector 2 is applied to the right car lamp. The changing rule of the width of the reflecting cavity 21 is opposite to the changing rule of the reflecting cavity 21 shown in FIG. 15. In the light distribution screen The upper part forms the right car light emitting light shape with the pixel width gradually decreasing from the outer area of the light shape to the center area of the light shape. The left car light emitting light shape and the right car light emitting light shape are superimposed to form a wide pixel width on both sides and a middle pixel width Narrow high beam light shape. 17 is a schematic diagram of another front view structure when the multi-cavity reflector 2 is applied to the left car lamp and the right car lamp. The multi-cavity reflector 2 applied to the left car lamp and the right car lamp has the same structure, and the reflection cavity 21 The width gradually decreases from both sides to the middle, and the superimposed light shapes of the left and right car lights can also form a high beam shape with a wide pixel width on both sides and a narrow middle pixel width.
优选地，如图25至图27所示，各所述发光光源1为单芯片发光光源且能够独立点亮，使得在实际应用时，通过控制各个发光光源的亮灭，可以实现对应像素的亮暗，从而能够灵活实现自适应远光照明。Preferably, as shown in FIGS. 25-27, each of the light-emitting light sources 1 is a single-chip light-emitting light source and can be independently lit, so that in practical applications, by controlling the on and off of each light-emitting light source, the corresponding pixel can be brightened. Dark, which can flexibly realize adaptive high-beam lighting.
在上述实施方式中，具体地，所述第一反射器4的反射面为平面，所述第一反射器4由上到下向远离所述发光光源1的方向倾斜设在所述多腔反射器2的正前方，以使由多腔反射器2汇聚反射过来的光线经第一反射器4反射后能够入射到第二反射器3的反射面。通过将第一反射器4的反射面设为平面，能够更好地控制光线的出射方向，保证更多的光线入射到第二反射器3的反射面上。当然，第一反射器4的反射面也可以为其它可以反射光线的曲面。In the above-mentioned embodiment, specifically, the reflecting surface of the first reflector 4 is a flat surface, and the first reflector 4 is inclined from top to bottom to the direction away from the light-emitting light source 1 and is arranged on the multi-cavity reflector. Directly in front of the reflector 2 so that the light converged and reflected by the multi-cavity reflector 2 can be incident on the reflecting surface of the second reflector 3 after being reflected by the first reflector 4. By setting the reflecting surface of the first reflector 4 as a plane, the exit direction of the light can be better controlled, and more light can be incident on the reflecting surface of the second reflector 3. Of course, the reflective surface of the first reflector 4 can also be other curved surfaces that can reflect light.
具体地，如图9所示，所述第二反射器3包括具有段差的两个反射面，即第二反射器3由具有段差的两个反射面拼接而成，两个反射面优选采用抛物面反射面。两个反射面分别对应一个焦点，相比采用具有一个焦点的一个反射面，光形效果会更好，同时，如果第二反射器3的反射面为一个整体的反射面，反射面在左右方向上的宽度需要做到很大，才能保证得到需要的光形，而将反射面分隔为两个，可以对两个反射面分别进行设计调整，从而使得第二反射器3的反射面不需要做到很大，就能形成预期光形。另外，由于第二反射器3具有两个反射面，为了防止窜光，影响光效，优选地，所述两个反射面之间设有隔板31。Specifically, as shown in FIG. 9, the second reflector 3 includes two reflecting surfaces with a step difference, that is, the second reflector 3 is formed by splicing two reflecting surfaces with a step difference, and the two reflecting surfaces are preferably parabolic. Reflective surface. Two reflective surfaces correspond to a focal point respectively. Compared with a reflective surface with a focal point, the light shape effect will be better. At the same time, if the reflective surface of the second reflector 3 is an integral reflective surface, the reflective surface is in the left and right directions. The width of the upper surface needs to be large to ensure that the required light shape is obtained. If the reflecting surface is divided into two, the two reflecting surfaces can be designed and adjusted separately, so that the reflecting surface of the second reflector 3 does not need to be made. When it is very large, the expected light shape can be formed. In addition, since the second reflector 3 has two reflective surfaces, in order to prevent light channeling and affect the light effect, preferably, a partition 31 is provided between the two reflective surfaces.
