具体实施方式
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，本发明的保护范围并不局限于下述的具体实施方式。
首先需要说明的是，在下文的描述中为清楚地说明本发明的技术方案而涉及的一些方位词，例如“前”、“后”、“上”、“下”、“左”、“右”等，均是按照光传输方向所指的方位类推所具有的含义，例如，以像素化照明单元1为例，像素化光源11所在的一端为后，像素化出光透镜12所在的一端为前，而相对于像素化照明单元1的前后方向，像素化照明单元1的左右两侧所代表的方向即为左右方向，像素化照明单元1的上下两侧所代表的方向即为上下方向。术语为基于附图所示的方向或位置关系，仅是为了便于描述本发明和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本发明的限制。
在本发明的描述中，需要说明的是，除非另有明确的规定和限定，术语“连接”、“设置”、“安装”应做广义理解，例如，连接可以是固定连接，也可以是可拆卸连接，或者是一体连接；可以是直接连接，也可以是通过中间媒介间接连接，或者是两个元件内部的连通或两个元件的相互作用关系。对于本领域的普通技术人员而言，可以根据具体情况理解上述术语在本发明中的具体含义。
本发明第一方面提供的照明模组，参见图2至图12，包括至少一个像素化照明单元1和至少一个非像素化照明单元2，像素化照明单元1包括像素化光源11和像素化出光透镜12，非像素化照明单元2包括非像素化光源21和非像素化出光透镜22，像素化出光透镜12与非像素化出光透镜22一体成型或连接为一体。
本发明中，将像素化照明单元1与非像素化照明单元2设置在同一模组内，针对该模组设置散热装置即可实现对像素化照明单元1与非像素化照明单元2整体进行散热；像素化光源11可以设置为多个能够独立控制亮灭的LED发光单元，具体可以为矩阵式排布的LED颗粒或者Micro LED，优选为Micro LED光源，即一种微缩LED光源，该微缩LED光源中的各个LED发光单元的尺寸为微米级别，且该微缩LED光源进一步优选为由上万颗微米级LED单元所组成的矩形阵列式LED光源；选用微缩LED光源能够使得像素点更小更密集，从而能够使得形成的像素图像的清晰度更高，进而能够实现对像素图像投射出去后所形成的光形进行更高精度的调控，形成的暗部的边界以及暗部位置的变化也更加精细流畅，能够更好地避免对行人或驾驶员造成炫目或致盲，而 且该微缩LED光源呈矩形阵列，能够获得更宽的光形，以照亮道路两侧的区域，有利于驾驶员对道路两侧的行人以及路标的观察。
本发明的照明模组中，像素化照明单元1和非像素化照明单元2的数量可以根据照明模组所需要形成的光形进行设置，具体地，像素化光源11设置为多个LED发光单元时，可以利用一个或者多个像素化照明单元1中部分LED发光单元发光形成的光形作为部分近光光形，相应地，利用一个或者多个非像素化照明单元2形成非像素化近光光形200，配合部分近光光形以形成完整的车辆前照灯近光照明用的光形；或者可以利用一个或者多个像素化照明单元1中部分LED发光单元发光形成的光形作为部分远光光形，相应地，利用一个或者多个非像素化照明单元2形成非像素化远光光形300，配合部分远光光形以形成完整的车辆前照灯远光照明用的光形。其中，部分近光光形可以为近光中心区域光形，非像素化近光光形200可以为用于近光展宽照明的辅助近光光形；部分远光光形可以为远光中心区域光形，非像素化远光光形300可以为用于远光展宽照明的辅助远光光形。
基于本发明的基础方案所提供的照明模组，参见图3，使用时根据所需要形成的光形打开相应的像素化光源11和非像素化光源21，像素化光源11的所有LED发光单元发出的光线能够经像素化出光透镜12投射形成像素化光形100，非像素化光源21发出的光线能够经非像素化出光透镜22投射形成非像素化近光光形200和/或非像素化远光光形300；在需要形成完整的近光光形时，打开像素化光源11上对应形成部分近光光形的LED发光单元和能够形成非像素化近光光形200的非像素化光源21，以使得非像素化近光光形200与部分近光光形相配合形成完整的近光光形；在需要形成完整的远光光形时，打开像素化光源11中对应形成部分远光光形的LED发光单元和能够形成非像素化远光光形300的非像素化光源21，以使得非像素化远光光形300与部分远光光形相配合形成完整的远光光形。本发明的照明模组将像素化照明单元1与非像素化照明单元2设置于同一个模组中，不仅能够便于对照明模组进行调光与散热，还能够有效减小照明模组的体积，降低生产成本；将像素化出光透镜12与非像素化出光透镜22设置为一体成型或连接为一体，能够提高所形成的近光光形、远光光形的精度和稳定性，同时，使得照明模组的出光面的造型效果好。
本发明中，非像素化照明单元2可以仅设置非像素化光源21和非像素化出光透镜22，即非像素化光源21发出的光线经非像素化出光透镜22直接投射形成相应的光形。作为本发明中非像素化照明单元2的一种优选实施方式，参见图6至图12，非像素化照 明单元2还包括非像素化初级光学元件23，非像素化初级光学元件23包括非像素化近光初级光学元件231和/或非像素化远光初级光学元件232，非像素化光源21包括与非像素化近光初级光学元件231对应设置的非像素化近光光源211和/或与非像素化远光初级光学元件232对应设置的非像素化远光光源212；非像素化近光初级光学元件231位于非像素化近光光源211与非像素化出光透镜22之间，非像素化远光初级光学元件232位于非像素化远光光源212与非像素化出光透镜22之间。非像素化初级光学元件23能够对非像素化光源21发出的光线进行汇聚、准直并传输至非像素化出光透镜22，以提高非像素化照明单元2的光学效率。通过非像素化近光初级光学元件231的设置，使得非像素化照明单元2能够形成非像素化近光光形200，非像素化远光初级光学元件232的设置，使得非像素化照明单元2能够形成非像素化远光光形300；根据非像素化近光初级光学元件231和/或非像素化远光初级光学元件232，非像素化光源21设置为相应的非像素化近光光源211和/或非像素化远光光源212，在非像素化初级光学元件23包括非像素化近光初级光学元件231和非像素化远光初级光学元件232时，非像素化光源21设置为能够独立控制亮灭的非像素化近光光源211和非像素化远光光源212，在需要形成非像素化近光光形200时，打开非像素化近光光源211、关闭非像素化远光光源212，在需要形成非像素化远光光形300时，打开非像素化远光光源212、关闭非像素化近光光源211。
本发明中，参见图11，非像素化近光初级光学元件231和非像素化远光初级光学元件232可以设置为导光元件，两者为上下设置，一般情况下将非像素化近光初级光学元件231设置在非像素化远光初级光学元件232的上方；本发明中所述的导光元件指的是具有光线传输通道的实心光学元件。参见图12，非像素化初级光学元件23还可以设置为反射镜，此时可以通过设置相应的遮光板实现非像素化远光与非像素化近光之间的切换。
作为本发明的一种优选实施方式，非像素化近光初级光学元件231和非像素化远光初级光学元件232为导光元件，此时，参见图9，非像素化近光初级光学元件231的出光面下边界位于其对应的非像素化出光透镜22的焦点区域内，且非像素化近光初级光学元件231的主***于其对应的非像素化出光透镜22的光轴上方；参见图10，非像素化远光初级光学元件232的出光面上边界位于其对应的非像素化出光透镜22的焦点区域内，且非像素化远光初级光学元件232的主***于其对应的非像素化出光透镜22的光轴下方。非像素化近光初级光学元件231的出光面下边界或者非像素化远光初级光 学元件232的出光面上边界可以是正好经过其对应的非像素化出光透镜22的焦点，也可以与其对应的非像素化出光透镜22的焦点有少许距离(≤2mm)的偏差，以使得非像素化近光初级光学元件231和非像素化远光初级光学元件232能够分别与相应的光源和非像素化出光透镜22配合，形成所需的非像素化光形。
作为导光元件的一种优选实施方式，参见图13至图17，非像素化近光初级光学元件231和非像素化远光初级光学元件232分别包括由后向前且一体成型的初级光学元件入光端233、初级光学元件光通道234和初级光学元件出光端235，其中初级光学元件入光端233的成型材料与初级光学元件光通道234和初级光学元件出光端235的成型材料不同，使得导光元件不仅能够满足对光线进行汇聚、准直的光学性能，还具有更好的耐热性能。具体地，初级光学元件入光端233由硅胶材质成型，初级光学元件光通道234和初级光学元件出光端235由聚碳酸酯(简称PC)材质成型。
优选情况下，初级光学元件入光端233与该初级光学元件入光端233对应的初级光学元件光通道234之间的分界面设置为前凸曲面，能够使得导光元件具有更好的二次配光作用，使得接收到的光线更集中，进一步提高导光元件的光传输效率，使得光形效果更优。
作为本发明的另一种优选实施方式，在像素化出光透镜12与非像素化出光透镜22为一体的基础上，像素化出光透镜12的出光面设置为外凸曲面，非像素化出光透镜22的出光面设置为延伸曲面，即非像素化出光透镜22的出光面为沿着像素化出光透镜12的出光面曲面向外延伸的曲面，同时像素化出光透镜12的出光面与非像素化出光透镜22的出光面连接为曲率连续的顺滑曲面，使得照明模组的出光面整体性好，出光面造型更优。
作为本发明中像素化照明单元1的一种优选实施方式，参见图5、图7至图12，像素化照明单元1还包括成像透镜组13，成像透镜组13包括至少一个成像透镜，像素化光源11、至少一个成像透镜与像素化出光透镜12由后向前依次排列，即成像透镜组13设置在像素化光源11和像素化出光透镜12之间。在成像透镜组13包括至少两个成像透镜时，至少两个成像透镜由后向前依次排列在像素化光源11和像素化出光透镜12之间。通过成像透镜组13与像素化出光透镜12的配合作用，有利于像素化照明单元1的成像，以形成相应的像素化光形100，还能够对投射成像过程中产生的色散进行抵消，使得投射出去的像素光形色差小，不易产生令人炫目的杂散光，有利于平衡光学***的像差，保证成像清晰度，提高像素化照明单元1的光效。
具体地，成像透镜组13包括由后向前依次排列的第一成像透镜131和第二成像透镜132，第一成像透镜131设置为入光面与出光面均呈外凸曲面的双凸透镜，第二成像透镜132设置为入光面呈内凹曲面、出光面呈外凸曲面的凸凹透镜，像素化出光透镜12设置为入光面与出光面均呈外凸曲面的双凸透镜。将第一成像透镜131设置为入光面与出光面均呈外凸曲面的具有正折射光焦度的双凸透镜，能够使得第一成像透镜131的焦距更短、屈光度更高，从而能够减小第一成像透镜131与像素化光源11间的距离；将第二成像透镜132设置为入光面呈内凹曲面、出光面呈外凸曲面的具有负折射光焦度的凸凹透镜，能够对光线经过第一成像透镜131折射后产生的色散现象进行抵消和修正，还能够减小其与第一成像透镜131和像素化出光透镜12之间的距离；将像素化出光透镜12设置为入光面与出光面均呈外凸曲面的具有正折射光焦度的双凸透镜，能够减小其与第二成像透镜132之间的距离，从而能够有效减小像素化照明单元1的前后长度尺寸，使得照明模组体积小、制造成本低。上述透镜的折射光焦度代表透镜处理光线的能力，正折射光焦度代表透镜能够使进入的光线汇聚，而负折射光焦度代表透镜能够使进入的光线发散。第一成像透镜131、第二成像透镜132和像素化出光透镜12的搭配方式，能够有效的抵消光线折射过程中的色散，使得像素光形的色散范围小，从而使得成像更加清晰，光形效果好。
