参见图1-图78所示，本发明的车灯光学元件组件包括初级光学元件11和次级光学元件21，光线能够依次经过所述初级光学元件11和所述次级光学元件21后投射形成照明光形，所述初级光学元件11包括沿出光方向依次设置的至少一个入光部112、通光部113和出光部114，光线由所述入光部112进入初级光学元件11，经所述通光部113后由所述出光部114出射。
所述入光部112可以为多种形式的聚光结构，例如可以是如图13-图14所示的呈聚光杯状的结构或者朝向远离所述通光部113方向的凸出结构。聚光杯的外部轮廓面为由后向前口径逐渐扩大的曲面结构，其入光面可以是平面，也可以是如图18所示的后端开设有开口向后的凹腔1121，所述凹腔1121的底部设有朝向远离所述通光部113方向凸出的凸起1122，以汇聚更多的光线，提高光效。
如图3和图73所示，所述初级光学元件11位于两侧的所述入光部112的光轴向靠近所述次级光学元件21的光轴方向倾斜，所述出光部114为内凹弧面；或者，
如图31所示，所述入光部112的光轴方向与所述次级光学元件21的光轴方向相同，所述出光部114的横向截线为向前凸出的弧线，以使所述出光部114的出射光线向中间集中，实现光线基本都能进入小宽度的次级光学元件21，
如图32所示，所述出光部114的纵向截线配置为向前凸出的弧线，使得该方向上出射光线向中间集中，可以将次级光学元件21的高度做小。
优选地，所述出光部114的纵向截线由所述初级光学元件11的出光部114的下边界向上、向后逐渐弯曲。
如图39所示，所述初级光学元件11的下表面相对于次级光学元件光轴211向后下方倾斜，倾斜角度≤15°，优选5°～10°，可以进一步使更多出射光线射入次级光学元件21，提高光效。
如图54所示，所述初级光学元件11的上下表面之间的间距由后向前逐渐减小，以使光线在上下方向上汇聚，形成高亮度光形。
上述车灯光学组件可应用于各种模组，包括主近光模组、辅助近光模组、近光模组、主远光模组、辅助远光模组、远光模组和双光模组，不同在于根据各自的光形要求进行不同结构的车灯光学组件的选择并进行相应的配光即可。
本发明第二方面提供的车辆照明模组包括沿出光方向自后向前依次设置的散热器3、电路板4、光源5以及上述的车灯光学元件组件，所述光源5电连接在所述电路板4上；所述车辆照明模组还包括用于支撑所述初级光学元件11的初级光学元件支架12a或初级光学元件支架12b或初级光学元件支架12c和用于支撑所述次级光学元件21的次级光学元件支架22a或次级光学元件支架22b或次级光学元件支架22c。
次级光学元件21和次级光学元件支架22a或次级光学元件支架22b或次级光学元件支架22c为一体成型件，进一步地，次级光学元件支架22a可以作为遮光罩使用，防止漏光，如图1所示的模组结构，其既有支撑作用也有遮光作用，其与次级光学元件21通过双色注塑成型，所述次级光学元件21选用透明材料(透明塑料、硅胶等)，所述次级光学元件支架22a选用深色遮光材料(黑色PC等)。而对于图52、图59中所示的次级光学元件支架22b和次级光学元件支架22c，其仅具有支撑作用。
如图6和图7所示，所述次级光学元件21的上下两端与所述次级光学元件支架22a之间形成有开口225。该开口225用于增加进入次级光学元件21的光线，提高光效。如图8和图9所示，不设开口的话，射至该位置的光线会被具有吸光功能的次级光学元件支架22a吸收，而不能进入次级光学元件21。当然，该开口也可以不用设置。
本发明的车辆照明模组的初级光学元件11和次级光学元件21的相对位置固定至少有两种表现形式，一种是所述初级光学元件支架12a能够和所述次级光学元件支架22a插接或所述初级光学元件支架12c能够和所述次级光学元件支架22c插接以将所述初级光学元件11和次级光学元件21的相对位置固定，所述次级光学元件支架22a或次级光学元件支架22c与所述散热器3固定连接；另一种是所述初级光学元件支架12b和所述次级光学元件支架22b均与所述散热器3固定连接，以将所述初级光学元件11和次级光学元件21的相对位置固定。
以下通过三种具体实施例来详细说明上述车辆照明模组的两种表现形式。
【车辆照明模组的第一种实施例】
如图6、图8、图11和图14所示，所述初级光学元件支架12a包括形成于所述初级光学元件11两侧的***定位部1101，所述次级光学元件支架22a上设有能够与所述***定位部1101插接的插槽221a。
具体地，所述插槽221a贯通所述次级光学元件支架22a的后端且从后向前延伸，初级光学元件11可由后方从插槽221a的开口向前***。所述***定位部1101的前端面与所述插槽221a内侧的前表面2211a(如图20所示)相接触，后端面与电路板4表面接触，以限制初级光学元件11相对次级光学元件支架22a前后移动；所述***定位部1101的顶面与所述插槽221a内侧的上表面2212a(如图21所示)相接触，所述***定位部1101的底面与所述插槽221a内侧的下表面2213a(如图20所示)相接触，以限制初级光学元件11相对次级光学元件支架22a上下移动。
初级光学元件11的材料为透明材质的塑料(PC、PMMA等)、硅胶或玻璃，材料优选硅胶。初级光学元件11的材料为硅胶时，参见图13、图16-图19以及图24-图27所示，在所述***定位部1101上与所述插槽221a相接触的表面上设置有凸起结构111。利用硅胶受力后的变形相比PC、PMMA等塑料较大的这一特性，使硅胶体的初级光学元件11在所述次级光学元件支架22a的接触力作用下被压紧，两者过盈配合，提高初级光学元件11的安装可靠性。
如图10-图11所示，所述次级光学元件支架22a的前端的左右内侧设有弧形挡板223，如图12所示，弧形挡板223用于遮挡进入次级光学元件21并出射后形成杂散光的光线，从而可以消除杂散光。也就是说该弧形挡板223遮掉的光线如果进入次级光学元件21并由次级光学元件21折射后会形成杂散光(照明光形以外的光，统称为无效光)。弧形挡板223设置为弧形的原因是：次级光学元件21中部的入射光线比上下两端多，弧形可以实现既能遮蔽形成杂散光的光线，又能避免过多地遮蔽用于形成照明光形的光线，也就是说，如果挡板为矩形，会过多地遮蔽次级光学元件21上下两端的入射光线，其中会包含用于形成照明光形的光线。
如图2和图6所示，所述次级光学元件支架22a的后端上设有次级光学元件支架安装孔222a，对应地，在所述散热器3和所述电路板4上设有与之对应的安装孔，散热器3上的安装孔为螺纹孔，采用螺钉6依次穿过次级光学元件支架安装孔222a、电路板4上的安装孔和散热器3上的安装孔以将所述次级光学元件支架22a安装在所述散热器3和所述电路板4上。
具体地，如图2和图3所示，所述散热器3上设有散热器定位销31，所述初级光学元件11上设有能够与所述散热器定位销31配合的初级光学元件定位孔122，对应地，所述电路板4上设有电路板初级定位孔41，所述散热器定位销31穿过所述电路板初级定位孔41并与所述初级光学元件定位孔122配合以将所述初级光学元件11限位于所述散热器3和所述电路板4上；如图2和图6所示，所述次级光学元件支架22a后端面上设有次级光学元件支架定位销224a、所述散热器3上设有散热器次级定位孔、所述电路板4上设有电路板次级定位孔42，所述散热器次级定位孔和所述电路板次级定位孔42与所述次级光学元件支架定位销224a配合以将所述次级光学元件21限位于所述散热器3和所述电路板4上。
如图3和图13所示，所述初级光学元件定位孔122的数量优选有两个，一个为与所述散热器定位销31周面接触的圆孔，另一个为与所述散热器定位销31间隙配合的腰形孔。如果两个初级光学元件定位孔122均为圆 孔，则散热器定位销31的位置需要非常精确才能顺利将散热器定位销31***初级光学元件定位孔122中，增加加工难度，而且很容易造成过定位，因此将其中一个初级光学元件定位孔122设为腰形孔，只要将其中一个散热器定位销31对准圆孔，另一个散热器定位销31将很容易***腰形孔，而定位精度并不会降低。所述初级光学元件11上开设有连通所述圆孔与外界的通气孔1221，以防止散热器定位销31***圆孔后压缩空气而引起初级光学元件11变形，影响其光学***的精度，进一步影响光形效果。
所述次级光学元件21的出光面的上下和左右两个方向中至少有一个方向的尺寸≤35mm，优选≤15mm，以实现次级光学元件21小开口的要求。次级光学元件21优选透镜。
该实施例的车辆照明模组可以是主近光模组、辅助近光模组、主远光模组或辅助远光模组，不同在于根据各自的光形要求进行不同结构的车灯光学组件的选择并进行相应的配光即可。
主近光模组
如图14、图15所示，所述主近光模组的出光部114的下边界设置为截止部115，该截止部115的形状与近光明暗截止线的形状相匹配。
如图16所示，所述主近光模组的出光部114为内凹弧面，与次级光学元件21的焦面相适应，使光形中心区域的光形清晰。
如图14-图15所示，所述主近光模组的初级光学元件11的下表面靠近所述出光部114的位置开设有向上凹陷、用于形成50L暗区光形的凹陷部116，用于改变部分光线的光路，实现降低50L暗区亮度的功能，即原本射至该位置处的光线会因为凹陷部116的存在改变光传输方向，不会射至50L暗区，从而使50L暗区亮度达到法规要求。
所述主近光模组的次级光学元件21的焦距为10～30mm，优选15mm、20mm、25mm、30mm。
所述主近光模组的整体尺寸为：前后方向(长)70～120mm，左右方向(宽)50～80mm，上下方向(高)20～40mm。
为了做到在次级光学元件21左右宽度很小的情况下，初级光学元件11的出射光线尽可能多地进入次级光学元件21，同时还能实现光形中心区域亮度高，所述主近光模组位于两侧的所述入光部112的光轴向靠近次级光学元件光轴211方向倾斜，以使其光线向中间集中，保证初级光学元件11的光线基本都能进入次级光学元件21。
上述主近光模组投射形成的光形如图5所示。
辅助近光模组
参见图30-图39所示，辅助近光模组与上述主近光模组安装结构相同，不同在于辅助近光模组投射形成的光形的展宽角度很大，为了形成展宽角度很大的近光展宽区域光形，需要初级光学元件11和次级光学元件21各个光学面的配合，经过两者配光得到合适展宽角度的光形。下面是其中一种实现方式。
上述主近光模组中的初级光学元件11中，为了做到在次级光学元件21左右宽度很小的情况下，初级光学元件11的出射光线尽可能多地进入次级光学元件21，同时还能实现光形中心区域亮度高，如图38中的上图位于两侧的入光部112的光轴相对于次级光学元件光轴211倾斜设置，均向靠近次级光学元件光轴211的方向倾斜，以使其光线向中间集中，保证初级光学元件11的光线基本都能进入次级光学元件21。由于各光源5设置在同一电路板4上，光源5的光轴与位于两侧的入光部112的光轴之间具有一定的角度，这导致光效不够高。因此，为了实现在次级光学元件21较小宽度的情况下还不损失光效，如图38中的下图所示，将所述辅助近光模组的所有入光部112配置为其光轴方向均与次级光学元件光轴211方向相同，同时，将初级光学元件11的出光部114的横向截线设置为向前凸出的弧线，以使出射光线向中间集中，实现光线基本都能进入小宽度的次级光学元件21。同样，如图39所示，可将初级光学元件11的出光部114的纵向截线也设置为向前凸出的弧线，使得该方向上出射光线向中间集中，可以将次级光学元件21的高度做小。如图33-图39所示，辅助近光模组的纵向截线由初级光学元件11的出光部114的下边界处向上向后逐渐弯曲，次级光学元件21焦点优选设置在该下边界上，该初级光学元件11的下表面相对于次级光学元件光轴211向后下方倾斜，倾斜角度小于等于15°，优选5°～10°，可以进一步使更多出射光线射入次级光学元件21，提高光效。
所述辅助近光模组的初级光学元件11的出光部114上的任一点的半径为5～150mm，优选7～25mm，具体数值根据实际配光情况来定。
如图38-图39所示(图38的上图是主近光模组横向剖面示意图、下图是辅助近光模组横向剖面示意图，图39的上图是主近光模组纵向剖面示意图、下图是辅助近光模组纵向剖面示意图)，为了实现大展宽角度的近光展宽区域光形，该辅助近光模组的次级光学元件21的出光面相比主近光模组的次级光学元件21的出光面的凸出程度更大，以使由进入透镜的光线能够发生更大角度的折射，以得到更宽的展宽角度。
由于该辅助近光模组的次级光学元件21可以使该模组形成大展宽角度的光形，因此，如图34和图37所示，可在所述辅助近光模组的初级光学元件11的下表面设有用于形成近光III区光形的III区结构117，该III区结构117与次级光学元件21配合可形成宽度较大的近光III区光形。所述III区结构117设置于所述通光部113中段，具有楔形结构并且厚度由后向前逐渐增大。
所述III区结构117的出光面为平面或者曲面，其左右方向上的宽度为2～5mm，优选3mm，上下方向的高度为0.2～1mm，优选0.4mm。
由于该辅助近光模组用于形成近光展宽光形，其初级光学元件11的下边界形状无需与近光明暗截止线的形状相匹配。
主近光模组和辅助近光模组的初级光学元件11也可以互换使用，只要通过配光调节各光学面参数满足所要光形即可。
含III区结构117的辅助近光模组投射形成的光形如图40所示；不含III区结构117的辅助近光模组投射形成的光形如图41所示；不含III区结构117的辅助近光模组叠加主近光模组投射形成的光形如图42所示。
主远光模组、辅助远光模组与上述主近光模组区别点是现有技术中根据远光特性而具有的常规区别结构，在此不一一列举。
【车辆照明模组的第二种实施例】
参见图59-图68所示，所述初级光学元件支架12c包括支撑架1201和限位件1202，所述限位件1202固设于所述初级光学元件11上，所述支撑架1201上设有限位槽1203，所述限位件1202与所述限位槽1203配合连接并与所述支撑架1201相对固定；通过限位件1202与支撑架1201的配合连接，使得初级光学元件11与支撑架1201相对固定，实现了将初级光学元件11定位支撑在初级光学元件支架12c上，即，限位件1202和支撑架1201装配在一起构成支撑初级光学元件11的初级光学元件支架12c。在一种较佳的实施方式中，支撑架1201的上表面部分下沉形成限位槽1203，使得限位槽1203的底面朝上且为水平面，限位件1202的下表面为水平面，限位件1202置于限位槽1203中，且限位件1202的下表面与限位槽1203的底面接触配合。
为增加限位件1202与支撑架1201之间装配定位的准确性，所述限位件1202上设有限位件定位孔1204，所述限位槽1203内设有与所述限位件定位孔1204插接配合的初级光学元件支架定位销1205。在将限位件1202安装到支撑架1201上时，通过初级光学元件支架定位销1205与限位件定位孔1204的插接配合，可以限定限位件1202与支撑架1201的相对位置，对限位件1202进行准确定位，从而实现初级光学元件11与初级光学元件支架12c之间的准确定位。
参见图59、图60、图65和图66所示，所述次级光学元件支架22c上设有插槽221c，所述初级光学元件支架12c与所述插槽221c插接配合，且所述初级光学元件支架12c具有与所述插槽221c内侧的表面相接触的定位面。通过初级光学元件支架12c的定位面与插槽221c内侧表面的接触配合，可以限定初级光学元件支架12c与次级光学元件支架22c的相对位置，使得初级光学元件支架12c与次级光学元件支架22c相对固定，实现初级光学元件支架12c与次级光学元件支架22c之间的装配定位，具有安装方便、定位可靠的优点。
与初级光学元件11的左、右两侧分别设有一个限位件1202，相匹配地，次级光学元件支架22c的左、右两侧分别设有一个插槽221c，两个插槽221c之间为供初级光学元件11***的装配空间。两个限位件1202分别装配到支撑架1201上对应的限位槽1203内后，与支撑架1201构成整体***相应的插槽221c中，从而实现初级光学元件支架12c与次级光学元件支架22c的装配，初级光学元件11则位于两个插槽221c之间的装配空间内。
为便于初级光学元件支架12c与次级光学元件支架22c的装配，并使得次级光学元件21位于初级光学元件11的前方，优选地，次级光学元件21设于次级光学元件支架22c的前端，所述插槽221c贯通所述次级光学元件支架22c的后端且从后向前延伸，由此，使得初级光学元件支架12c能够从插槽221c的后端***插槽221c内并沿图61中直线箭头所示方向向前进入插槽221c内，直至初级光学元件支架12c的定位面与插槽221c内侧的表面接触配合到位，支撑在初级光学元件支架12c上的初级光学元件11则位于次级光学元件21的后方。
所述插槽221c贯通所述次级光学元件支架22c的后端且从后向前延伸，为保证初级光学元件支架12c的定位面与插槽221c内侧表面的接触配合能够有效限定初级光学元件支架12c与次级光学元件支架22c的相对位置，所述支撑架1201的前端面与所述插槽221c内侧的前表面2211c相接触，所述支撑架1201的后端面与所述电路板4的表面相接触，以限制初级光学元件支架12c相对次级光学元件支架22c向前移动；所述限位件1202的顶面与与所述插槽221c内侧的上表面2212c相接触，以限制初级光学元件支架12c相对次级光学元件支架22c向上移动；所述支撑架1201的底面与所述插槽221c内侧的下表面2213c相接触，以限制初级光学元件支架12c相对次级光学元件支架22c向下移动。本实施例中，支撑架1201位于限位槽1203正前方的前端面构成初级光学元件支架12c的前定位面；限位件1202装配到支撑架1201上的限位槽1203内后，限位件1202的顶面高于支撑架1201的顶面，因此限位件1202的顶面构成初级光学元件支架12c的上定位面；支撑架1201的底面构成初级光学元件支架12c的下定位面。参见图60所示，在一种较佳的实施方式中，插槽221c内侧的上表面有部分凹陷而不与限位件1202的上表面接触配合，插槽221c内侧的下表面有部分凹陷而不与支撑架1201的下表面接触配合，由此可以减小插槽221c内侧的上表面与限位件1202的上表面的接触面积、插槽221c内侧的下表面与支撑架1201的下表面的接触面积，形成小面积接触定位，小面积的接触面的加工精度更容易保证，可使得初级光学元件支架12c的定位面与插槽221c内侧的表面之间更好地接触，从而使定位更精准。
进一步，插槽221c沿左右方向贯通次级光学元件支架22c，所述次级光学元件支架22c设于或者一体形成于所述次级光学元件21的左右两侧，所述支撑架1201的左、右两侧分别设有一个卡合部1206，两个所述卡合部1206相对的内侧面分别与所述次级光学元件支架22c的左、右侧面相接触，以限制初级光学元件支架12c相对次级光学元件支架22c左右移动。在一种较佳的实施方式中，两个卡合部1206分别设于支撑架1201的左、右两侧侧面上且均向前延伸至支撑架1201前端面的前方，装配后，支撑架1201的前端面与插槽221c内侧的前表面相接触，两个卡合部1206则位于次级光学元件支架22c的外侧，且两个卡合部1206的内侧面分别与次级光学元件支架22c的左侧面、右侧面位于插槽221c前方的区域相接触配合。为使初级光学元件支架12c的卡合部1206能够通过插槽221c的后端到达插槽221c前方外侧，如图66所示，次级光学元件支架22c的后端设有前后贯通次级光学元件支架22c的通槽226，通槽226的开口朝向插槽221c并在插槽221c的外侧与插槽221c的后端相连通，当支撑架1201和限位件1202***插槽221c内时，位于支撑架1201侧面的卡合部1206从通槽226通 过并到达插槽221c前方外侧。
参见图62、图66和图68所示，优选地，初级光学元件支架12c的后端具有用于与电路板4的表面相接触的后定位面，次级光学元件支架22c的后端面上设有用于与电路板4的表面相接触的突出部227。在将车灯光学元件组件安装在电路板4上时，通过初级光学元件支架12c的后定位面与电路板4的表面接触配合、次级光学元件支架22c后端的突出部227与电路板4的表面接触配合，可以限制初级光学元件支架12c相对次级光学元件支架22c向后移动，并将车灯光学元件组件定位在电路板4的表面上。支撑架1201的后端面构成初级光学元件支架12c的后定位面。优选地，可以在次级光学元件支架22c的后端面上的左、右两侧分别设置一个突出部227。通过在次级光学元件支架22c的后端面上设置与电路板4的表面相接触的突出部227，避免了次级光学元件支架22c的后端面整体与电路板4的表面相接触，减小了次级光学元件支架22c后端与电路板4表面的接触面积，形成小面积接触定位，小面积的接触面的加工精度更容易保证，可使得突出部227与电路板4的表面之间更好地接触，从而使定位更精准。
综上，本实施例的车灯光学元件组件，通过初级光学元件支架12c与次级光学元件支架22c的配合连接，将初级光学元件11与次级光学元件21装配成一整体结构而直接确定了两者的相对位置，实现了初级光学元件11与次级光学元件21之间的直接定位。并且，通过初级光学元件支架12c的前定位面(支撑架1201的前端面)与次级光学元件支架22c插槽221c内侧的前表面2211c相接触，限制了初级光学元件支架12c相对次级光学元件支架22c向前移动，通过初级光学元件支架12c的上定位面(限位件1202的顶面)与插槽221c内侧的上表面2212c相接触，限制了初级光学元件支架12c相对次级光学元件支架22c向上移动，通过初级光学元件支架12c的下定位面(支撑架1201的底面)与插槽221c内侧的下表面2213c相接触，限制了初级光学元件支架12c相对次级光学元件支架22c向下移动，通过初级光学元件支架12c上两个卡合部1206相对的内侧面分别与次级光学元件支架22c的左侧面、右侧面相接触，限制了初级光学元件支架12c相对次级光学元件支架22c左右移动，通过初级光学元件支架12c的后定位面(支撑架1201的后端面)与电路板4的表面接触配合、次级光学元件支架22c后端的突出部227与电路板4的表面接触配合，限制了初级光学元件支架12c相对次级光学元件支架22c向后移动，由此，实现了初级光学元件支架12c与次级光学元件支架22c在前后、上下、左右方向上的相对固定，保证了初级光学元件支架12c与次级光学元件支架22c全方位定位精度以及安装稳定性，即保证了初级光学元件11与次级光学元件21的定位精度以及安装稳固性，使得车灯光学元件组件在长时间使用后仍能保持初级光学元件11与次级光学元件21的相对位置不变，从而保证车灯光形的准确性和稳定性。此外，将初级光学元件11和次级光学元件21装配成一整体结构、确定了初级光学元件11与次级光学元件21的相对位置后，再将该整体结构安装到电路板4和散热器3上，可降低电路板4与散热器3的定位精度要求，使得安装过程更为简单便捷。
初级光学元件支架12c、次级光学元件支架22c与散热器3、电路板4、光源5的定位安装结构属于现有技术，在此不作赘述。
另外，需要说明的是，本实施例中的初级光学元件11设置于其后端面上的至少一个入光部未在图中示出。
