具体实施方式
为了能够更清楚地理解本公开的上述目的、特征和优点，下面将对本公开的方案进行进一步描述。需要说明的是，在不冲突的情况下，本公开的实施例及实施例中的特征可以相互组合。
在下面的描述中阐述了很多具体细节以便于充分理解本公开，但本公开还可以采用其他不同于在此描述的方式来实施；显然，说明书中的实施例只是本公开的一部分实施例，而不是全部的实施例。
结合图1、图2、图3、图4、图5和图6所示，本公开实施例提供的光导结构包括：光源1、内面罩2和厚壁3，光源1发出的光线发射至内面罩2并依次经内面罩2和厚壁3后射出，可以使发光面发光均匀，通过光源1和内面罩2、厚壁3之间的配合，可以实现优秀的车辆灯具发光效果，消除了发光时的颗粒感，提升了用户体验。
厚壁3为一体式结构，从设计上去除多个灯之间的物理间隙，使结构上更连贯，形成静态、点亮状态下的浑然一体均匀点亮的贯穿效果。静态下，厚壁3结构为贯穿式，结构上不间断，视觉效果一致，点亮状态下，使发光面为一体式均匀点亮的贯穿。一体式结构的厚壁3使发光面均匀发光，发光面无间断，无明显暗区。
在一些具体的实施方式中，光导结构包括：光源1、内面罩2、厚壁3和反射镜4，反射镜4用于将光源1发出的光线反射至内面罩2并依次经内面罩2和厚壁3后射出，反射镜4将光源1发出的光线反射至内面罩2并依次经内面罩2和厚壁3后射出，可以使发光面发光均匀，通过光源1和内面罩2、厚壁3之间的配合，可以实现优秀的车辆灯具发光效果，消除了发光时的颗粒感，提升了用户体验。
厚壁3和反射镜4通过紧固件连接，内面罩2设置于厚壁3和反射镜4之间。通过厚壁3和反射镜4连接，可以将内面罩2卡在厚壁3和反射镜4之间，使内面罩2和厚壁3可以紧紧贴在一起，提高发光面发光均匀性。其中，紧固件可以是螺钉，也可以是枪钉。
反射镜4设置于光源1的上方，内面罩2设置于反射镜4的前方，厚壁3设置于所述内面罩2的前方。需要说明的是，前方是指壳体5或灯室的外面罩6所向的一面，换言之，前方是靠外远离车辆的一侧。
沿厚壁3的延伸方向Y，厚壁3包括第一端31和第二端32，第一端31到第二端32的距离可以根据灯具的长度需求设置、或者说根据车辆宽度设置，使厚壁3有较长的发光面，可以满足点亮需求。厚壁3长度可以大于1500mm，可以最大化提升点亮长度，可以点亮较大区域，满足消费者的造型需求，使车灯更自然体现流线性和灯光艺术性，能给消费者展现车灯的造型和灯光的美感。通过内面罩2和厚壁3的配合，使发光面发光均匀。当从正面看车灯时，效果美观，整个厚壁3点亮的时候光的亮度比较均匀，提升了用户体验。
需要说明的是，延伸方向Y为车辆的宽度方向。
需要说明的是，内面罩2可以为任意满足透光率要求的材料制成，可选的，内面罩2 由光透过率大于或等于90％的材料制成。可选的，内面罩2为用于光学均匀化的薄壁注塑件，厚壁3可以为任意满足透光率要求的材料制成，可选的，厚壁3由光透过率大于或等于90％的材料制成，可选的，厚壁3为用于光学均匀化的注塑件，反射镜4可以为金属材质也可以为塑料材质，可选的，反射镜4为镀铝的或者不镀铝的一种用于光线聚焦的塑料注塑件。
还需要说明的是，内面罩2可以用光扩散材料制成。可选的，内面罩2可以为聚碳酸酯(PC)光扩散塑料，即以透明PC塑料为基材，添加一定比例的光扩散剂以及其它助剂经过特殊工艺聚合而成的一种透光而不透明的光扩散材料颗粒。可选的，光扩散材料可以为在无色透明PC基材中添加BaSO 4等对光线有散射作用的材料制成。可选的，光扩散材料还可以为在无色透明PC基材中添加大分子团材料等对光线产生散射作用的材料制成。可选的，内面罩2由无色透明PC基材添加BaSO 4或大分子团材料制成。
内面罩2为一体式结构，从设计上去除多个灯之间的物理间隙，使结构上更连贯，形成静态、点亮状态下的浑然一体均匀点亮的贯穿效果。静态下，内面罩2为贯穿式，使结构上不间断；点亮状态下，使发光面为一体式均匀点亮的贯穿，视觉效果一致，一体式结构的内面罩2使发光面均匀发光，发光面无间断，无明显暗区。
光源1包括线路板和LED光源，线路板可以是PCB板也可以是PCBA板。线路板和LED光源电连接使LED光源可以点亮，也可以熄灭。
在一些具体的实施方式中，内面罩2包括第一入光面21和第一出光面22，厚壁3包括第二入光面33和第二出光面34；第一出光面22到第二入光面33的距离L1(图中未示出)满足：0≤L1≤1mm。反射镜4将光源1发出的光线反射至内面罩2并依次经内面罩2和厚壁3后射出，可以使第二出光面34发光均匀。通过内面罩2和厚壁3之间的配合，可以实现优秀的车辆灯具发光效果，消除了第二出光面34发光时的颗粒感，提升了用户体验。第一出光面22到第二入光面33的距离可以为0、0.2mm、0.4mm、0.6mm、0.8mm、1mm等0到1毫米之间的任意数，当第一出光面22到第二入光面33的距离在0到1mm之间时，均可以使发光面发光均匀，即满足，线性比值≥75％。线性比值可以反映线性分布均匀性，其是指在贯穿线(即厚壁3的第二出光面34上沿厚壁3延伸方向(即Y方向)的连续延伸线)上的亮度的最小值min和最大值max之比。例如，根据本申请的结构，测得第二出光面34的贯穿线上的亮度分布(单位nit)曲线，其满足条件A：min/max＞75％；B：且在未均化数据前提下线性数据波动范围Δ＜最小值min的10％。进一步，灯具的发光面的均匀性还可以采用点域的亮度分布来衡量，其中对发光面上某一区域(例如圆形、四边形区域等)的多个点(例如10至100个)的亮度进行测量，通过比较其中点亮度(单位nit)的最小值Nmin和最大值Nmax之比Nmin/Nmax(即区域性比值)来评价该发光面的均匀性。其中，对每一点进行多次测量，所测得的亮度的平均值作为该点的亮度值。根据本申请的灯具在第二出光面34满足Nmin/Nmax＞0.9。
第一出光面22到第二入光面33的距离越小，发光的均匀性越好。
可选的，当第一出光面22到第二入光面33的距离为0时，第一出光面22与第二入光 面33紧密贴合，没有间隙，使第二出光面34发光面均匀发光，消除第二出光面34发光时的颗粒感，可以实现优秀的车辆灯具发光效果，提升用户体验。

如图5所示，壳体5沿厚壁3的延伸方向Y延伸，壳体5延伸方向的两端部之间的距离M2以大于或等于1500mm，使壳体5与厚壁3长度基本一致，最大化提升了点亮长度。壳体5为一体式结构，从设计上去除多个灯具之间的物理间隙，使结构上更连贯，形成静态、点亮状态下的浑然一体均匀点亮的贯穿效果。静态下，结构不断，视觉效果一致，点亮状态下，使发光面为一体式贯穿，发光面无间断，无明显暗区。
外面罩6的延伸长度与壳体5相适配，如图4所示，外面罩6沿厚壁3的延伸方向Y延伸，外面罩6延伸方向的两端部之间的距离M1大于或等于1500mm，使外面罩6与厚壁3长度基本一致，最大化提升点亮长度。外面罩6为一体式结构，从设计上去除多个灯之间的物理间隙，使结构上更连贯，形成静态、点亮状态下的浑然一体均匀点亮的贯穿效果。静态下，结构不断，点亮状态下，使发光面为一体式贯穿，发光面均匀，发光面无间断，无明显暗区。
