Description

一种带自适应功能的LED双光模组 技术领域
本发明属于汽车灯具技术领域，尤其涉及一种带自适应功能的LED双光模组。
背景技术
随着车灯技术的发展，汽车前照灯正照得越来越亮，越来越远，与之带来的是眩目现象更为明显，远光造成对向来车司机眼睛眩目，也是导致夜间交通事故的主要原因之一。近年来，矩阵式LED双光技术飞快发展，矩阵式LED双光车灯成为了汽车车灯未来发展的方向之一。矩阵式LED双光前照灯是多颗LED阵列排布，在前置摄像头的配合下，由系统自动控制每颗LED的亮暗变化，在特定区域形成暗区，避免远光对道路上其他车辆及行人的影响。
目前矩阵式LED双光技术应用并未成熟，矩阵式LED双光前照灯大多结构复杂、光线出光均匀性较差和出光效率低。如现有专利CN209415340U公开了一种LED双光模组，其具体披露了“第二LED线路板固定散热器前端的上部，第三内灯罩和第一LED线路板固定在散热器前端的下部，第二内灯罩与第一内灯罩装配成一体后与第三内灯罩、第二固定片定位安装，凸透镜通过透镜支架内卡脚固定在透镜支架的前端，透镜支架定位安装在散热器的前端；第一内灯罩前部为光顺的内凹曲面，第一内灯罩的后部为光顺的外凸曲面，第一内灯罩的上部曲面局部镀铝，第二内灯罩前部为光顺的内凹曲面，第二内灯 罩的后部为多个并行的条形导光柱，第三内灯罩前部布置了多个彼此并排相邻的玉米粒形状的外凸发光面，外凸发光面成单排或多排布置；第二LED线路板、第二内灯罩、第一内灯罩和凸透镜组成近光光学系统，第一LED线路板、第三内灯罩、第一内灯罩和凸透镜组成远光ADB光学系统。”该远光ADB光学系统主要通过第三内灯罩接收LED光源出射的光线，准直后入射到第一内灯罩做光束整形，形成远光部分的截止线，光线从第三内灯罩到第一内灯罩中，即穿过各个光学表面时，有能量损失，能量利用率大大降低；另外该远光ADB光学系统包括多个内灯罩，导致光线出光均匀性较差、结构复杂、装配精度低，以及加工成本高。
发明内容
为解决现有技术存在的矩阵式LED双光前照灯结构复杂、光线出光均匀性较差和出光效率低的问题，本发明提供一种带自适应功能的LED双光模组。
为解决上述技术问题，本发明所采用的技术方案如下，一种带自适应功能的LED双光模组，包括从前至后依次设置的凸透镜、内灯罩机构、LED线路板机构和散热器；所述内灯罩机构包括第一内灯罩、第二内灯罩和灯罩支架，所述第一内灯罩与灯罩支架为嵌件成型，所述第二内灯罩通过第一固定片与灯罩支架装配成一体，所述第一内灯罩位于第二内灯罩的下方，所述灯罩支架固定设置在散热器上；所述LED线路板机构包括第一LED线路板和第二LED线路板，所述第一LED 线路板固定设置在散热器的前端下部，所述第二LED线路板固定设置在散热器的前端上部；该LED双光模组还包括透镜支架，所述凸透镜固定设置在透镜支架的前端，所述透镜支架的后端与散热器固定连接，所述内灯罩机构和LED线路板机构均位于透镜支架内；所述第二LED线路板、第二内灯罩和凸透镜组成近光光学系统，所述第一LED线路板、第一内灯罩和凸透镜组成远光ADB光学系统；所述第一内灯罩的前端发光面为光顺的内凹曲面，所述第一内灯罩的后端为岔开的多个并行的条形导光柱，所述第二内灯罩的前端发光面为光顺的内凹曲面，所述第二内灯罩的后端为多个并行的圆柱状导光柱。
作为优选，所述第一内灯罩的上表面增加皮纹处理。第一内灯罩和第二内灯罩合并到一起后，皮纹结构起隔断作用，有效防止第一内灯罩和第二内灯罩合并到一起发生窜光。
作为优选，所述第一内灯罩和第二内灯罩的材质均选用硅胶。硅胶材质便于加工制造，满足光学性能要求，耐热性能佳。
作为优选，所述第二内灯罩的多个圆柱状导光柱由中间向两边叉开，下部面型实现近光截止线形状。光线出光均匀性好。
作为优选，所述第一LED线路板上设置有第一LED光源和第一接插件，所述第二LED线路板上设置有第二LED光源和第二接插件，所述第一接插件和第二接插件均用于接通电源。
作为优选，所述灯罩支架的上部和后端均设有定位销，上部的所述定位销用于第二内灯罩与灯罩支架的预定位；后端的所述定位销用于灯罩支架与第一LED线路板的预定位。定位销的设置提高第二内灯 罩、灯罩支架和第一LED线路板的装配精度。
进一步地，所述第二LED线路板通过第二固定片固定设置在散热器的前端上部，所述第二固定片上开设有多个孔位，多个所述孔位用于定位第二内灯罩的圆柱状导光柱；所述第一固定片和第二固定片的材质均选用金属。第二内灯罩和第二LED线路板的装配结构简单牢靠，提高第二内灯罩和第二LED线路板之间的定位精度。
进一步地，所述散热器的后端具有多个散热翅片，相邻所述散热翅片之间设有间隙，散热器前端开设有多个通孔。散热器的结构合理紧凑，散热功能好。
进一步地，所述第一LED线路板与散热器之间，以及第二LED线路板与散热器之间均设置有导热脂层。便与散热，提高散热效果。
进一步地，所述散热器的后端设置有风扇。风扇便于给该LED双光模组进一步散热，提高散热效果。
有益效果：
本发明的带自适应功能的LED双光模组，将近光和远光ADB巧妙地整合到一起，可以实现理想的双光光型，实现远光ADB光学系统时，仅通过第一内灯罩对光束完成准直和整形，因光线在从一个介质到另一个介质中，即穿过光学表面时，会有能量损失，现有技术的从LED光源出射的光线经过四次光学面，而本申请只经过两次光学面，能量利用率大大提高；
本发明的带自适应功能的LED双光模组，结构简单，相比现有技术，减少了内灯罩的设置，光效得到较大提高，减少了装配，生产工 序简化，同时减少了偏差，生产一致性得到提高；
本发明的带自适应功能的LED双光模组，满足了远光ADB功能的需求，可实现多个分区，避免了对行人或对向司机造成眩目，有效减少夜间交通事故。
