下面将结合附图，对本申请中的技术方案进行描述。The technical solutions in this application will be described below with reference to the accompanying drawings.
为了便于理解本申请实施例，作出以下说明。In order to facilitate understanding of the embodiments of the present application, the following description is provided.
第一、在下文示出的本申请实施例中的文字说明或者附图中的术语，“第一”、“第二”等以及各种数字编号仅为描述方便进行的区分，而不必用于描述特定的顺序或者先后次序，并不用来限制本申请实施例的范围。例如，在本申请实施例中用于区分不同的光束以及不同的光源等。First, the terms "first", "second", etc. and various numerical numbers in the description of the embodiments of the present application or in the drawings shown below are only for convenience of description and are not necessarily used for distinction. Describing a specific sequence or sequence is not intended to limit the scope of the embodiments of the present application. For example, in the embodiment of the present application, it is used to distinguish different light beams and different light sources.
第二、下文示出的本申请实施例中的术语“包括”和“具有”以及它们的任何变形，意图在于覆盖不排他的包含，例如，包含了一系列步骤或单元的过程、方法、***、产品或设备不必限于清楚地列出的那些步骤或单元，而是可以包括没有清楚地列出的或对于这些过程、方法、产品或设备固有的其他步骤或者单元。Second, the terms "including" and "having" and any variations thereof in the embodiments of the present application shown below are intended to cover non-exclusive inclusions, for example, processes, methods, and systems that include a series of steps or units. , products, or devices need not be limited to those steps or units that are expressly listed, but may include other steps or units that are not expressly listed or that are inherent to the processes, methods, products, or devices.
第三、在本申请实施例中，“示例性的”或者“例如”等词用于表示例子、例证或说明，被描述为“示例性的”或者“例如”的实施例或设计方案不应被解释为比其它实施例或设计方案更优选或更具优势。使用“示例性的”或者“例如”等词旨在以具体方式呈现相关概念，便于理解。Third, in the embodiments of this application, words such as "exemplary" or "for example" are used to express examples, illustrations or illustrations, and embodiments or designs described as "exemplary" or "for example" should not are to be construed as preferred or advantageous over other embodiments or designs. The use of words such as "exemplary" or "such as" is intended to present related concepts in a concrete manner that is easier to understand.
第四、在本申请实施例中，成像光均是指携带有图像(或图像信息)的光，用于生成图像。Fourth, in the embodiments of this application, imaging light refers to light that carries an image (or image information) and is used to generate an image.
第五、在本申请实施例中，曲面反射镜的面型不做限定，例如，可以是自由曲反射面镜等。Fifth, in the embodiment of the present application, the surface shape of the curved mirror is not limited. For example, it can be a free-curved mirror.
第六、在本申请实施例中，“投射”并不限定于单一的指代透射或者反射。可用来表示反射或者透射，具体地，根据实施例中光路的方向来决定。Sixth, in the embodiments of this application, "projection" is not limited to simply referring to transmission or reflection. It can be used to represent reflection or transmission, specifically, it is determined according to the direction of the light path in the embodiment.
图1示出了本申请实施例提供的光机模组的一种应用场景的示意图。如图1所示，光机模组可以设置在汽车车灯上，构成ADB***。ADB***用于通过视频摄像头信号的输入，判断前方来车的位置与距离，并相应调整灯光照射区域，关闭或调暗对面车辆区域的灯光照射，避免对来车产生炫光，同时最大限度地满足驾驶者的视野需求。除了可以实现ADB，光机模组还可以在地面上投射高清晰度的符号图标，提高驾驶安全性，以及投射图片视频，实现丰富的智能车灯交互场景。Figure 1 shows a schematic diagram of an application scenario of the optical-mechanical module provided by the embodiment of the present application. As shown in Figure 1, the opto-mechanical module can be installed on the car lights to form an ADB system. The ADB system is used to determine the position and distance of the oncoming vehicle through the input of the video camera signal, and adjust the lighting area accordingly, turn off or dim the lighting in the area of the opposite vehicle, to avoid glare on the oncoming vehicle, and at the same time maximize the Meet the driver’s vision needs. In addition to realizing ADB, the optical-mechanical module can also project high-definition symbols and icons on the ground to improve driving safety, as well as project pictures and videos to realize rich intelligent car light interaction scenarios.
然而，为了实现大视场角的精细ADB***，通常需要采用双模组形式，其中一个可采用百万以下像素模组来实现大视场角照明，另一个模组为百万级别分辨率的模组，例如采用DMD调制单元，来负责ADB的中心区域的精细成像。但该方案性存在整灯配置和控制复杂，功耗上升的缺点，适用的车型有限。因此，本申请提供的光机模组，能够实现单模组的ADB***，以较小的成本实现较大的视场角(field of view，FOV)。 However, in order to realize a fine ADB system with a large field of view, it is usually necessary to adopt a dual module form. One of them can use a sub-million pixel module to achieve large field of view illumination, and the other module can use a million-level resolution. Modules, such as DMD modulation units, are responsible for fine imaging of the central area of the ADB. However, this solution has the disadvantages of complex lamp configuration and control, increased power consumption, and limited applicable models. Therefore, the optical-mechanical module provided by this application can realize a single-module ADB system and achieve a larger field of view (FOV) at a lower cost.
图2示出了本申请实施例提供的一种光机模组200的结构示意图。如图2所示，该模组200包括第一发光模块210、第二发光模块220、折光元件250、调制模块260。其中，第一发光模块210用于出射第一光束至折光元件250，通过折光元件250将第一光束入射至调制模块260。第二发光模块220用于出射传输方向不同的第二光束至折光元件250，使得第二光束通过折光元件250入射至调制模块260的不同位置。折光元件250用于将第一光束和第二光束光路折叠，并投射第一光束和第二光束至调制模块260。调制模块260用于根据图像数据对折光元件250出射的第一光束和第二光束进行调制，生成成像光，并出射成像光。FIG. 2 shows a schematic structural diagram of an optical-mechanical module 200 provided by an embodiment of the present application. As shown in FIG. 2 , the module 200 includes a first light-emitting module 210 , a second light-emitting module 220 , a refractive element 250 , and a modulation module 260 . The first light-emitting module 210 is used to emit the first light beam to the refractive element 250, and the first light beam is incident to the modulation module 260 through the refractive element 250. The second light-emitting module 220 is used to emit second light beams with different transmission directions to the refractive element 250, so that the second light beam passes through the refractive element 250 and is incident on different positions of the modulation module 260. The refractive element 250 is used to fold the optical paths of the first beam and the second beam, and project the first beam and the second beam to the modulation module 260 . The modulation module 260 is used to modulate the first light beam and the second light beam emitted from the refractive element 250 according to the image data, generate imaging light, and emit the imaging light.
示例性的，该折光元件250可以是自由曲面镜或者棱镜等，用于将接收到的第一光束和第二光束的光路折叠，使第一光束与第二光束入射至调制模块260。For example, the refractive element 250 may be a free-form mirror or a prism, which is used to fold the optical paths of the received first beam and the second beam, so that the first beam and the second beam are incident on the modulation module 260 .
在一种可实现的方式中，若该折光元件250是曲面反射镜，该曲面反射镜的曲率可以是均匀分布的。此时，对第二光束的利用率最高。In an implementable manner, if the refractive element 250 is a curved mirror, the curvature of the curved mirror may be evenly distributed. At this time, the utilization rate of the second beam is the highest.
在另一种可能的实现方式中，该曲面镜反射镜的曲率不是均匀分布的，且曲率是分区域分布时，该曲面镜反射镜能够将第一光束反射至照亮整个调制模块260的有效像面区域，而使得第三光束照亮该有效像面的区域中的目标区域。In another possible implementation, when the curvature of the curved mirror reflector is not uniformly distributed, and the curvature is distributed in regions, the curved mirror reflector can reflect the first light beam to an effective area that illuminates the entire modulation module 260 . The image plane area is such that the third beam illuminates the target area in the effective image plane area.
调制模块260也可以称为成像引擎。Modulation module 260 may also be referred to as an imaging engine.
在一种可实现的方式中，调制模块260可以是反射型的空间光调制器，例如为LCoS调制器。此时，该光机模组200可以包括偏振转换器件，该偏振转换器件可以设置于LCoS的输入端位置处，用于将入射的光束的偏振态转换为LCoS调制器需要的偏振态。In an implementable manner, the modulation module 260 may be a reflective spatial light modulator, such as an LCoS modulator. At this time, the optical machine module 200 may include a polarization conversion device, which may be disposed at the input end of the LCoS for converting the polarization state of the incident light beam into the polarization state required by the LCoS modulator.
在另一种可实现的方式中，调制模块260还可以是反射型的空间光调制器且不具有改变入射的线偏振光的偏振方向的功能，例如为MEMS或者DMD。In another implementable manner, the modulation module 260 may also be a reflective spatial light modulator without the function of changing the polarization direction of the incident linearly polarized light, such as a MEMS or DMD.
在另一种可实现的方式中，调制模块260还可以是透射型的空间光调制器，例如LCD等。In another implementable manner, the modulation module 260 may also be a transmissive spatial light modulator, such as an LCD.
本申请中的调制模块260可根据不同的场景需要进行适当的调整，在此不作限定。The modulation module 260 in this application can be appropriately adjusted according to the needs of different scenarios, and is not limited here.
在一种可实现的方式中，该第一发光模块210可以包括面发光半导体光源，例如，发光二极管(Light emitting diode，LED)。该LED光源出射的第一光束通过折光元件250反射后，照亮调制单元260的整个有效像面区域。该第二发光模块220可以包括激光半导体(Laser diode，LD)光源，即激光二极管。In an implementable manner, the first light emitting module 210 may include a surface emitting semiconductor light source, such as a light emitting diode (Light emitting diode, LED). The first light beam emitted from the LED light source is reflected by the refractive element 250 and illuminates the entire effective image area of the modulation unit 260 .

基于上述方案，本申请通过第二发光模块实现对入射光的亮度的增强，从而使得成像区域的像面亮度增强。即通过增加光源光通量来使得总体投影光通量增加，相较于仅有第一发光模块的光机模组来讲，能够在保持中心亮度不变的情况下增大视场角。同时，由于第二光束入射至调制模块的位置可变，即第二光束能够照亮调制单元260的有效像面中的不同区域，使得光机模组200投影的图像中亮度增强的位置也随之发生变化，即生成亮度随动的投影图像。Based on the above solution, this application uses the second light-emitting module to enhance the brightness of the incident light, thereby enhancing the brightness of the image surface of the imaging area. That is, by increasing the luminous flux of the light source, the overall projection luminous flux is increased. Compared with an optical-mechanical module with only the first light-emitting module, the viewing angle can be increased while maintaining the center brightness unchanged. At the same time, since the position of the second light beam incident on the modulation module is variable, that is, the second light beam can illuminate different areas in the effective image plane of the modulation unit 260, so that the position where the brightness is enhanced in the image projected by the optical machine module 200 also changes accordingly. changes, that is, a projection image with varying brightness is generated.

The first phosphor 240 is used to receive the third light beam, generate the second light beam, and emit the second light beam. The second collimating lens group 2702 is used to collimate the second light beam emitted from the first phosphor 240 . The light beam emitted from the light source 2201 can be incident on different positions of the phosphor 240 through the rotation of the rotating mirror 230, and can be emitted from different positions of the phosphor 240.

示例性的，该光机模组200的控制单元用于控制转镜230的旋转角度，通过改变转镜230的旋转角度，使第二发光模块220中的光源2201产生的第三光束通过不同旋转角度的转镜230反射后，以不同的方向入射至第一荧光体240的不同位置上，使得第一荧光体240在不同的位置处产生的第二光束以不同的传输方向从第一荧光体240出射，进而经过准直透镜组2702以及折光元件250后，入射至调制模块260的不同位置。Exemplarily, the control unit of the optical engine module 200 is used to control the rotation angle of the rotating mirror 230. By changing the rotation angle of the rotating mirror 230, the third light beam generated by the light source 2201 in the second light-emitting module 220 can be rotated through different After reflection by the angled rotating mirror 230, it is incident on different positions of the first phosphor 240 in different directions, so that the second light beam generated by the first phosphor 240 at different positions is transmitted from the first phosphor in different directions. 240, and then passes through the collimating lens group 2702 and the refractive element 250, and then enters different positions of the modulation module 260.
其中，该转镜230的旋转角度可以根据反馈信息确定，其中，反馈信息用于指示成像光生成的图像中亮度加强的区域。The rotation angle of the rotating mirror 230 can be determined based on feedback information, where the feedback information is used to indicate areas with enhanced brightness in the image generated by the imaging light.
示例性的，该反馈信息用于输入至计算转镜230旋转角度的计算单元，计算单元通过该反馈信息计算出转镜的旋转角度，控制单元控制转镜230旋转至计算的角度。当第三光束通过转镜230反射至第一荧光体240后，激发第一荧光体240产生的第二光束以某一角度经过准直透镜组2702准直后，入射至折光元件250，经过折光元件250反射至调制模块260，产生的成像光投影的区域即为生成的图像中亮度加强的区域。For example, the feedback information is used to input to the calculation unit that calculates the rotation angle of the rotating mirror 230. The calculation unit calculates the rotation angle of the rotating mirror through the feedback information, and the control unit controls the rotating mirror 230 to rotate to the calculated angle. After the third light beam is reflected to the first phosphor 240 through the rotating mirror 230, the second light beam generated by exciting the first phosphor 240 is collimated by the collimating lens group 2702 at a certain angle, and then enters the refractive element 250 and undergoes refraction. The element 250 is reflected to the modulation module 260, and the area projected by the generated imaging light is the area with enhanced brightness in the generated image.
应理解，图3中的转镜230仅为示例而非限定，即能够改变第二光束出射角度的元件均在本申请的保护范围之内。It should be understood that the rotating mirror 230 in FIG. 3 is only an example and not a limitation, that is, elements capable of changing the exit angle of the second light beam are within the protection scope of the present application.
具体地，第一发光模块210用于照亮整个调制模块260的有效像面区域，第二发光模块可以用于照亮整个调制模块260的有效像面区域，或者照亮调制模块260的有效像面区域中的目标区域。换句话说，第一发光模块出射的光束用于照亮调制模块260的有效像面，使出射的成像光能够成像在成像区域内，第二发光模块出射的光束用于照亮调制模块260的有效像面中的目标区域，使得出射的成像光增强在成像区域中的目标区域的图像的亮度。Specifically, the first light-emitting module 210 is used to illuminate the effective image plane area of the entire modulation module 260, and the second light-emitting module can be used to illuminate the entire effective image plane area of the modulation module 260, or to illuminate the effective image of the modulation module 260. target area within the polygon area. In other words, the light beam emitted from the first light-emitting module is used to illuminate the effective image plane of the modulation module 260 so that the emitted imaging light can be imaged in the imaging area, and the light beam emitted from the second light-emitting module is used to illuminate the modulation module 260 . The target area in the effective image plane allows the emitted imaging light to enhance the brightness of the image of the target area in the imaging area.
示例性的，该第一发光模块210可以包括LED，该LED光源出射的第一光束通过折光元件250反射后，照亮调制单元260的整个有效像面区域。具体地，该LED光源出射的第一光束为白光。应理解，对于出射白光的LED光源来说，其内部或者外部封装有第二荧光体，使得LED光源发出的准单色光通过荧光体后出射白光。该第二发光模块220可以包括LD，该LD输出的第三光束为单色光。例如，蓝光或者紫光，当该蓝光或紫光(第三光束)入射到第一荧光体240后，一部分入射光的能量激发第一荧光体240产生黄光，该激发的黄光与剩余部分的入射光混合形成白光(第二光束)投射至折光元件250。For example, the first light-emitting module 210 may include an LED. After the first light beam emitted from the LED light source is reflected by the refractive element 250, it illuminates the entire effective image area of the modulation unit 260. Specifically, the first light beam emitted by the LED light source is white light. It should be understood that for an LED light source that emits white light, a second phosphor is packaged inside or outside the LED light source, so that the quasi-monochromatic light emitted by the LED light source passes through the phosphor and then emits white light. The second light emitting module 220 may include an LD, and the third light beam output by the LD is monochromatic light. For example, blue light or purple light. When the blue light or purple light (third beam) is incident on the first phosphor 240, part of the energy of the incident light excites the first phosphor 240 to produce yellow light. The excited yellow light is combined with the remaining part of the incident light. The light is mixed to form white light (the second light beam) and is projected to the refractive element 250 .
当要求该光机模组200出射的成像光实现增强成像区域中的目标区域的亮度时，第一发光模块照亮调制单元260的全部像面，第二发光模块220用于将调制单元260有效像面中的目标区域的亮度加强，从而使得出射的成像光的成像区域内目标区域的图像的亮度得到增强。When the imaging light emitted from the optical engine module 200 is required to enhance the brightness of the target area in the imaging area, the first light-emitting module illuminates the entire image plane of the modulation unit 260, and the second light-emitting module 220 is used to effectively activate the modulation unit 260. The brightness of the target area in the image plane is enhanced, so that the brightness of the image of the target area in the imaging area of the emitted imaging light is enhanced.
当要求该光机模组200出射的成像光实现较大面积的亮度增强图像投影，甚至增强整个成像区域的亮度时，则需要增大第三光束在该第一荧光体上的入射面积。When the imaging light emitted from the opto-mechanical module 200 is required to project a brightness-enhanced image over a larger area, or even enhance the brightness of the entire imaging area, the incident area of the third light beam on the first phosphor needs to be increased.
基于上述方案，本申请提供的光机模组，通过转镜实现对第二光束的传输方向的改变，使得经过折光元件的第二光束能够入射至调制模块的不同位置，从而实现对生成的图像中不同位置的图像的亮度增强。Based on the above solution, the opto-mechanical module provided by this application changes the transmission direction of the second light beam through a rotating mirror, so that the second light beam passing through the refractive element can be incident on different positions of the modulation module, thereby achieving control of the generated image. The brightness of images at different locations in the image is enhanced.
在一种可实现的方式中，图4示出了本申请实施例提供的一种光机模组400的结构示意图。如图4所示，该光机模组200还可以包括第一扩束元件280，具体地，该第一扩束元件 280位于转镜230与第一荧光体240之间的光路上。当需要第二光束照亮成像区域中的目标区域时，该第一扩束元件280可设置为不对第三光束进行扩束，仅通过第三光束。例如，该第一扩束元件280可以是液态透镜，通过改变电压来改变液态透镜的焦距，进而改变第二光束聚焦于第一荧光体240上的光斑大小。In an implementable manner, FIG. 4 shows a schematic structural diagram of an optical-mechanical module 400 provided by an embodiment of the present application. As shown in Figure 4, the optical engine module 200 may also include a first beam expansion element 280. Specifically, the first beam expansion element 280 280 is located on the optical path between the rotating mirror 230 and the first phosphor 240 . When the second beam is required to illuminate the target area in the imaging area, the first beam expansion element 280 can be configured not to expand the third beam and only pass the third beam. For example, the first beam expansion element 280 can be a liquid lens, and the focal length of the liquid lens is changed by changing the voltage, thereby changing the spot size of the second light beam focused on the first phosphor 240 .
示例性地，该第一扩束元件280可以包括移动装置，当不需要对第三光束进行扩束时，可将该第一扩束元件280移开。或者，当需要第二光束照亮成像区域整个像面区域时，利用该第一扩束元件280增大第三光束的横截面的面积，使得第三光束入射到第一荧光体240的面积变大，从而使出射的第二光束的横截面积变大，即实现了同时对第二光束的扩束。进一步地，该扩束后的第二光束经过折光元件250后，照亮调制单元的整个像面，从而使得调制单元出射的成像光的亮度均得到增强，进而使得该成像光成像区域内的图像亮度均得到增强。For example, the first beam expansion element 280 may include a moving device, and when the third beam does not need to be expanded, the first beam expansion element 280 can be moved away. Alternatively, when the second beam is required to illuminate the entire image area of the imaging area, the first beam expansion element 280 is used to increase the cross-sectional area of the third beam, so that the area of the third beam incident on the first phosphor 240 becomes Therefore, the cross-sectional area of the emitted second light beam becomes larger, that is, the second light beam is simultaneously expanded. Further, after the expanded second beam passes through the refractive element 250, it illuminates the entire image plane of the modulation unit, so that the brightness of the imaging light emitted from the modulation unit is enhanced, thereby making the image in the imaging area of the imaging light Brightness has been enhanced.
应理解，图4中的其他光学元件的作用，可参考图2或图3中的对应元件相关说明，此处不再赘述。It should be understood that for the functions of other optical elements in Figure 4, reference can be made to the relevant descriptions of the corresponding elements in Figure 2 or Figure 3, and will not be described again here.
在另一种可实现的方式中，可通过改变转镜230的面型，实现对第二光束的扩束。例如图5所示的转镜230，该转镜230包括第一区域和第二区域。例如，第一区域的面型为平面，第二区域的面型为凸面球面，光束通过第二区域会产生扩束效果。或者第一区域的面型和第二区域的面型可以采用其他形状，只要可以实现相应的功能即可，本申请对此不作限定。当需要第二光束照亮成像区域中的目标区域时，该转镜230通过第一区域将第三光束反射至第一荧光体240上。当需要第二光束照亮成像区域整个像面区域时，该转镜230通过第二区域将第三光束反射至第一荧光体240上，由于该凸面球面反射可以增大第三光束的发散角，因此，同样起到了对第三光束进行扩束的效果，即该第二区域能够增大第三光束的横截面的面积，使得第三光束入射到第一荧光体240的面积变大，从而使得出射的第二光束的横截面积变大，即实现同时对第二光束的扩束的效果。进一步地，该扩束后的第二光束经过折光元件250后，照亮调制单元的整个像面，从而使得调制单元出射的成像光的亮度均得到增强，进而使得该成像光成像区域内的图像亮度均得到增强。In another implementable manner, the second beam can be expanded by changing the surface shape of the rotating mirror 230 . For example, the rotating mirror 230 shown in FIG. 5 includes a first area and a second area. For example, if the surface shape of the first region is a plane and the surface shape of the second region is a convex spherical surface, the beam passing through the second region will produce a beam expansion effect. Or the surface shape of the first area and the surface shape of the second area can adopt other shapes, as long as corresponding functions can be achieved, and this application does not limit this. When the second light beam is required to illuminate the target area in the imaging area, the rotating mirror 230 reflects the third light beam to the first phosphor 240 through the first area. When the second beam is required to illuminate the entire image area of the imaging area, the rotating mirror 230 reflects the third beam to the first phosphor 240 through the second area. Due to the convex spherical surface reflection, the divergence angle of the third beam can be increased. , therefore, it also has the effect of expanding the third beam, that is, the second area can increase the cross-sectional area of the third beam, so that the area of the third beam incident on the first phosphor 240 becomes larger, so that The cross-sectional area of the emitted second light beam is enlarged, that is, the effect of simultaneously expanding the second light beam is achieved. Further, after the expanded second beam passes through the refractive element 250, it illuminates the entire image plane of the modulation unit, so that the brightness of the imaging light emitted from the modulation unit is enhanced, thereby making the image in the imaging area of the imaging light Brightness has been enhanced.
在另一种可实现的方式中，可以通过快速移动转镜的位置，实现对第三光束的扩束。例如图6所示的转镜230，该转镜230包括移动装置231，示例性的，该移动装置231可以是滑轨。当不需要对第三光束进行扩束时，该转镜230可以固定于某一位置处。当需要对该转镜230反射的第三光束进行扩束时，可通过将该转镜230在移动装置231上快速移动，使得反射的第三光束能够实现增大入射到第一荧光体240上的面积，从而起到对第三光束的扩束效果。In another feasible way, the third beam can be expanded by rapidly moving the position of the rotating mirror. For example, the rotating mirror 230 shown in FIG. 6 includes a moving device 231. For example, the moving device 231 may be a slide rail. When there is no need to expand the third beam, the rotating mirror 230 can be fixed at a certain position. When the third light beam reflected by the rotating mirror 230 needs to be expanded, the rotating mirror 230 can be quickly moved on the moving device 231 so that the reflected third light beam can be incident on the first phosphor 240 . area, thereby achieving a beam expansion effect on the third beam.
或者，在另一种可实现的方式中，可以通过快速偏转转镜230的角度，实现对第三光束的扩束。该方案可以理解为，当需要增大第三光束的横截面积时，可通过在较短的时间内不断的变换转镜230的偏转角度，使得经过转镜反射的第三光束形成一个大的扫描光束，以此起到对第三光束的扩束效果。Alternatively, in another implementable manner, the third beam can be expanded by rapidly deflecting the angle of the rotating mirror 230 . This solution can be understood as: when it is necessary to increase the cross-sectional area of the third beam, the deflection angle of the rotating mirror 230 can be continuously changed in a short period of time, so that the third beam reflected by the rotating mirror forms a large Scan the beam to expand the third beam.
应理解，上述无论是引入第一扩束元件280或者对转镜230的面型进行改变或者转镜230设置有移动装置231的目的，均可以理解为是为了实现对第三光束的扩束作用。上述方案可以单独使用，也可以结合使用，例如，可以在改变面型的转镜230上设置有移动装置，进一步的扩大反射的第三光束的横截面积，或者还可以使得第三光束在转镜的第一区域或第二区域切换。因此，其他在本申请实施例中未说明的能够实现对第三光束进行的扩束的实现方法，均应在本申请的保护范围之内。It should be understood that whether the purpose of introducing the first beam expanding element 280 or changing the surface shape of the rotating mirror 230 or providing the rotating mirror 230 with the moving device 231 can be understood as achieving the beam expansion effect of the third beam. . The above solution can be used alone or in combination. For example, a moving device can be provided on the rotating mirror 230 that changes the surface shape to further expand the cross-sectional area of the reflected third beam, or the third beam can also be rotated. Switch between the first or second area of the mirror. Therefore, other implementation methods that are not described in the embodiments of the present application and can realize beam expansion of the third beam should be within the protection scope of the present application.
基于上述方案，本申请提供的光机模组，通过增加扩束元件或者对转镜的调节，根据场 景的需要实现对第二光束横截面积的调节，从而能够实现对成像区域的亮度的灵活调控，继而满足更加丰富的场景应用。Based on the above solution, the optical-mechanical module provided by this application can be adjusted according to the field by adding beam expansion elements or adjusting the rotating mirror. The cross-sectional area of the second beam can be adjusted according to the needs of the scene, thereby enabling flexible control of the brightness of the imaging area, thereby satisfying a richer set of scene applications.

As shown in Figure 7, Figure 7 shows a schematic structural diagram of an optical engine module 700 provided by an embodiment of the present application. The first light-emitting module 210 includes a light source LD 2101, a second beam expansion element 212 and a second phosphor. 213. Among them, the second beam expansion element 212 is used to increase the cross-sectional area of the first beam emitted by the LD2101. The second phosphor 213 is used to receive the first beam emitted from the second beam expansion element 212, generate a fourth beam, and project the fourth beam to the refractive element 250. The first collimating lens group 2701 is used to collimate the fourth light beam emitted from the second phosphor 213 . It should be understood that the LD 2101 can only emit monochromatic light. Therefore, the first beam is monochromatic light, such as blue light or purple light. After the first beam passes through the second phosphor 213, it excites the second phosphor to produce yellow light. The generated yellow light and the remaining part of the first light beam together form a fourth light beam that is incident on the reflective surface of the refractive element 250 .

具体地，如图15所示，在图15中，该第二扩束元件1321能够根据需要的目标区域的大小实现对第三光束的横截面积的调节。例如，当目标区域为整个成像像面时，该第二扩束元件1321对第三光束的横截面积进行调节后，使得第一荧光体1340接收第三光束的面积增大，从而出射的第二光束也得到了扩束的效果，使得折光元件1350反射后的第二光束能够照亮调制元件1360的整个有效像面，从而使得出射的成像光能够将成像区域的全部像面的亮度增强。Specifically, as shown in Figure 15, in Figure 15, the second beam expansion element 1321 can adjust the cross-sectional area of the third beam according to the size of the required target area. For example, when the target area is the entire imaging image plane, the second beam expansion element 1321 adjusts the cross-sectional area of the third beam, so that the area of the first phosphor 1340 receiving the third beam is increased, so that the emitted third beam is The two beams also have a beam expansion effect, so that the second beam reflected by the refractive element 1350 can illuminate the entire effective image plane of the modulation element 1360, so that the emitted imaging light can enhance the brightness of the entire image plane of the imaging area.
具体地，如图16所示，在图16中，该转镜1330能够根据需要的目标区域的大小实现对第四光束的横截面积的调节。例如，当目标区域为整个成像像面时，该可通过控制转镜1330 的旋转角度使第三光束入射在转镜1330不同曲率的反射面上，从而对第三光束的横截面积进行调节，使得第一荧光体1340接收第三光束的面积增大，从而出射的第二光束也得到了扩束的效果，使得折光元件1350出射后的第二光束能够照亮调制元件1360的整个有效像面，使得出射的成像光能够将成像区域的全部像面的亮度增强。Specifically, as shown in FIG. 16 , in FIG. 16 , the rotating mirror 1330 can adjust the cross-sectional area of the fourth beam according to the size of the required target area. For example, when the target area is the entire imaging surface, the rotating mirror 1330 can be controlled to The rotation angle causes the third beam to be incident on the reflecting surface of different curvatures of the rotating mirror 1330, thereby adjusting the cross-sectional area of the third beam, so that the area of the first phosphor 1340 receiving the third beam increases, so that the outgoing third beam The two light beams also have a beam expansion effect, so that the second light beam emitted from the refractive element 1350 can illuminate the entire effective image plane of the modulation element 1360, so that the emitted imaging light can enhance the brightness of the entire image plane of the imaging area.
具体地，如图17所示，在图17中，该转镜1330包括移动装置1331，例如可以是滑轨，来实现对第三光束的横截面积的调节。例如，当目标区域为整个成像像面时，该可通过快速移动转镜1330使第三光束能够不断扫描第一荧光体1340，从而实现对第三光束的扩束，使得折光元件1350发射后的第二光束能够照亮调制元件1360的整个有效像面，使得出射的成像光能够将成像区域的全部像面的亮度增强。Specifically, as shown in Figure 17, in Figure 17, the rotating mirror 1330 includes a moving device 1331, which may be a slide rail, for example, to adjust the cross-sectional area of the third light beam. For example, when the target area is the entire imaging surface, the third beam can be continuously scanned by the first phosphor 1340 by rapidly moving the rotating mirror 1330, thereby achieving beam expansion of the third beam, so that the refractive element 1350 emits the The second light beam can illuminate the entire effective image plane of the modulation element 1360, so that the emitted imaging light can enhance the brightness of the entire image plane of the imaging area.

As shown in Figure 19, the vehicle light module includes the optical engine module shown in Figure 2 and an imaging lens 1910.

During the second time period, only the second light-emitting module of the optical-mechanical module works. At this time, the second light beam emitted from the second light-emitting module passes through the refractive element and is incident on the image plane of the modulation module, and is modulated by the modulation unit to generate The second imaging light is used for imaging. When the second imaging light is the imaging light emitted from the partial image plane of the modulation module, the imaging lens generates a partial image in the imaging area based on the second imaging light.
