请参阅图17，本申请还提供一种电子设备1000电子设备1000包括上述任意一实施方式的光学模组100及壳体200。光学模组100与壳体200结合。
下面结合附图对本申请的实施方式做进一步说明。
请参阅图1至图3，其中，透镜10由透光材料制成，例如由玻璃、塑料等制成。微结构122包括菲涅尔纹，具体地，菲涅尔纹表现为多个由小到大的同心圆，菲涅尔纹的截面呈锯齿状(如6所示)。在一个例子中，微结构122可以是相对透镜10的第一面12突出形成的多个同心圆(图3及图4所示)。在一个例子中，微结构122可以是相对透镜10的第一面12内凹形成的多个同心圆(图未示)。
在某些实施方式中，第一功能器件20可为发射器，对应的，第二功能器件30可为接收器，此时，导光器40用于将从外界进入透镜10内部并经微结构122折射后出射的光线传导至接收器。在另一些实施方式中，第一功能器件20为接收器，第二功能器件30为发射器，导光器40用于将从发射器发射的光线传导至透镜10的微结构122。在又一些实施方式中，第一功能器件20和第二功能器件30均为接收器。在再一些实施方式中，第一功能器件20和第二功能器件30均为发射器。
具体地，发射器包括：闪光灯、接近传感器的发射单元、飞行时间深度相机的红外光发射器、及结构光深度相机的红外光发射器中的至少一个。接收器包括：色温传感器、接近传感器的接收单元、飞行时间深度相机的红外光接收器、结构光深度相机 的红外光接收器、环境光传感器、及影像传感器中的至少一个。
在某些实施方式中，第一功能器件20与第二功能器件30在功能上具有对应关系，二者可配对使用以共同实现一个功能。此时，发射器发射的光线经过透镜10之后出射到外界，被外界的物体反射回再经过透镜10之后可被接收器接收并处理以实现相应的功能。在一个例子中，发射器是闪光灯，接收器为影像传感器时，闪光灯发出光线，光线经过透镜10出射至外界以实现对环境光线的补充，光线被外界的物体反射回并经过透镜10之后可被影像传感器接收，影像传感器处理该光线以成像。在另一个例子中，发射器是结构光深度相机的红外光发射器，接收器为结构光深度相机的红外光接收器时，结构光深度相机的红外光发射器发出红外光，红外光经过透镜10出射至外界，红外光被外界的物体反射回并经过透镜10之后可被结构光深度相机的红外光接收器接收，结构光深度相机的红外光接收器处理该光线以测距。在再一个例子中，发射器是飞行时间深度相机的红外光发射器，接收器为飞行时间深度相机的红外光接收器时，飞行时间深度相机的红外光发射器发出红外光，红外光经过透镜10出射至外界，红外光被外界的物体反射回并经过透镜10之后可被飞行时间深度相机的红外光接收器接收，飞行时间深度相机的红外光接收器处理该光线以测距。在又一个例子中，发射器是接近传感器的发射单元，接收器为接近传感器的接收单元时，接近传感器的发射单元发出红外光，红外光经过透镜10出射至外界，红外光被外界的物体反射回并经过透镜10之后可被接近传感器的接收单元接收，接近传感器的接收单元处理该光线以测距。
在某些实施方式中，第一功能器件20与第二功能器件30在功能上不具有对应关系，二者是独立工作并实现其各自的功能。此时，发射器发射的光线经过透镜10之后出外界以实现第一功能。外界的光线经过透镜10之后可被接收器接收并处理以实现第二功能。在一个例子中，发射器是闪光灯，接收器为色温传感器时，闪光灯发射的光线经过透镜10之后出外界以实现补光功能。外界的光线经过透镜10之后可被色温传感器接收并处理以实现检测色温的功能。在另一个例子中，发射器是闪光灯，接收器为环境光传感器时，闪光灯发射的光线经过透镜10之后出外界以实现补光功能。外界的光线经过透镜10之后可被环境光传感器接收并处理以实现检测环境光强的功能。
另外，第三正投影S3与第二正投影S2至少部分错开可以包括以下情况：在一个例子中，第三正投影S3与第二正投影S2完全错开，如图3所示，第三正投影S3与第二正投影S2相离，即二者完全没有重叠的部分。由于第一正投影S1位于微结构122在平面P1的第二正投影S2内，且第三正投影S3与第二正投影S2完全错开，使得第 一功能器件20与第二功能器件30间隔较远，在安装时彼此不会发生干涉，且可以减小在Z方向的厚度，从而降低光学模组100的厚度。
在另一个例子中，第三正投影S3与第二正投影S2部分错开(图未示)，第三正投影S3与第二正投影S2相交，即二者有重叠的部分，也有不重叠的部分。由于第一正投影S1位于微结构122在平面P1的第二正投影S2内，且第三正投影S3与第二正投影S2部分错开，使得第一功能器件20与第二功能器件30为位置上有部分重叠，光学模组100在XY平面内的面积较小，结构紧凑。
本申请的光学模组100将第一功能器件20与透镜10相对设置，并利用导光器40传导透镜10与第二功能器件30之间的光线，实现了第一功能器件20和第二功能器件30共用一个透镜10，减少透镜10的使用数量，相应地，无需在电子设备1000(图17所示)的壳体200(图17所示)上开设多个通孔210(图17所示)，降低电子设备1000的壳体200设计的复杂度。
在相关技术中，第一功能器件和第二功能器件可以全部放置在微结构的下方，并与微结构相对，此时无需设置导光器，第一功能器件和第二功能器件收发的光线直接通过透镜。然而，为了使得第一功能器件和第二功能器件均与微结构相对，且第一功能器件与菲涅尔中心对准，中心以外的一部分菲涅尔纹要与第二功能器件对准，则需要设计一个直径较大的透镜。本申请的光学模组100将第一功能器件20与透镜10相对设置，并利用导光器40传导透镜10与第二功能器件30之间的光线，无需设计一个较大直径的透镜10，即透镜10的直径相较前述设计的透镜直径较小，能节省透镜10的材料。
在另一相关技术中，第一功能器件和第二功能器件可以全部放置在微结构的下方，并与微结构相对，此时无需设置导光器，第一功能器件和第二功能器件收发的光线直接通过透镜。为了使得第一功能器件和第二功能器件均与微结构相对且均与微结构的中心对准，则虽然无需设计一个直径较大的透镜，但需要设计两个菲涅尔中心以分别与第一功能器件和第二功能器件对准，两个菲涅尔中心的设计可能会引起菲尼尔纹理不规则(不对称)。本申请的光学模组100将第一功能器件20与透镜10相对设置，并利用导光器40传导透镜10与第二功能器件30之间的光线，无需设计两个菲涅尔中心，不会出现菲尼尔纹理不规则的问题。
进一步地，光线透过普通的透镜时，会出现边角变暗、模糊的现象。以玻璃材质的凸透镜为例，凸透镜的镜片较厚，光在玻璃中直线传播的部分会使得光线衰减，从而出现边角变暗、模糊的现象。本实施方式中光学模组100的透镜10为具有菲涅尔纹的透镜，相较于普通的凸透镜去掉了光在透镜中直线传播的部分的光学材料，透镜 10只保留发生折射的曲面，在减少光线衰减的同时还能节约大量光学材料，可以实现与普通凸透镜达到相同的聚光效果的同时，透镜10的厚度更薄，且减少边角变暗、模糊的现象。
请参阅图3及图5，在某些实施方式中，菲涅尔纹的中心与第一功能器件20的中心对准。
第一功能器件20的中心指第一功能器件20的收发面22的中心。例如，第一功能器件20为发射器，具体地，第一功能器件20为闪光灯，则第一功能器件20的中心指闪光灯的发光区域的中心。或者，第一功能器件20为接收器，具体地，第一功能器件20为色温传感器，则第一功能器件20的中心指色温传感器的感光区域的中心。
菲涅尔纹的中心与第一功能器件20的中心对准可以最大化地发挥透镜10的辅助作用，例如当第一功能器件20为发射器时可以将发射器发射的光线自发光中心均匀地向外扩散，或者当第一功能器件20为接收器时，可以将外界入射的光线准确地汇聚到接收器的感应区域上。
在本实施方式中，可以选择对透镜10需求较高的器件作为第一功能器件20，选择对透镜10需求较低的器件作为第二功能器件30，并使第一功能器件20的中心与透镜10的菲涅尔纹的中心对准，从而最大化地发挥透镜10的辅助作用。
在一个例子中，第一功能器件20为闪光灯，第二功能器件30为色温传感器。其中，闪光灯需要使用透镜10将闪光灯发出的光线汇聚后向外界发射增强补光效果，提高暗光环境下的成像效果。而色温传感器仅需要通过透镜10接收来自外界的光线便可检测出色温。相比较而言，闪光灯对透镜10的需求较色温传感器对透镜10的需求更大，将闪光灯的中心与透镜10的菲涅尔纹的中心对准有利于最大化地发挥透镜10的辅助作用。
在另一个例子中，第一功能器件20为闪光灯，第二功能器件30为环境光传感器。其中，闪光灯需要使用透镜10将闪光灯发出的光线汇聚后向外界发射增强补光效果，提高暗光环境下的成像效果。而环境光传感器仅需要通过透镜10接收来自外界的光线便可检测出环境光强度。相比较而言，闪光灯对透镜10的需求较环境光传感器对透镜10的需求更大，将闪光灯的中心与透镜10的菲涅尔纹的中心对准有利于最大化地发挥透镜10的辅助作用。
请参阅图3，在某些实施方式中，第一功能器件20的收发面22与透镜10的第一面12之间的第一垂直距离d1小于第二功能器件30的收发面32与透镜10的第一面12之间的第二垂直距离d2。
具体地，第一垂直距离d1的设置根据第一功能器件20的类型而确定。例如当第 一功能器件20为闪光灯时，d1可以设置为0.3mm。第二垂直距离d2的设置是为了保证从透镜10的微结构122出射的光线在导光器40内部有足够的空间传播光线，及能够保证在导光器40内部的光线改变角度，以满足光线能够通过导光器40在透镜10的第一面12与第二功能器件30之间传导。
在其他实施方式中，第一功能器件的收发面与透镜的第一面之间的第一垂直距离可以大于或等于第二功能器件的收发面与透镜的第一面之间的第二垂直距离。即，在透镜10的光轴方向上，第二功能器件位于第一功能器件与透镜之间。此时，可以减小Z方向的厚度，从而降低光学模组100的厚度。
更具体地，请再参阅图1及图2，透镜10包括第一面12及第二面14，第一面12与第二面14相背，第一面12上设置有微结构122，第二面14上设置有凸台16，凸台16增加了透镜10的有效光学部的厚度，能够更好地传输光线。
下面以本实施方式以第一功能器件20为闪光灯，第二功能器件30为色温传感器，导光器40是用于将第一功能器件20发出的光线传导至外界，且将从透镜10的微结构122出射的光线传导至第二功能器件30为例进行说明。
请参见图7及图8，闪光灯20包括发光面22和安装面26。发光面22和安装面26相背设置，发光面22朝向透镜10的第一面12，发光面22具有发光中心24，该发光中心24与微结构122的中心对准。安装面26远离透镜10的第一面12，安装面26上设置有多个电连接件262，安装面26通过焊接等方式与电路板(图未示)机械连接，多个电连接件262用于实现电路板及闪光灯20的电连接。
请参见图9及图10，色温传感器30包括第一面31及第二面33，第一面31及第二面33相背设置，第一面31朝向透镜10的第一面12，第二面33远离透镜10的第一面12。第一面31具有一个感光区域，可定义为收光面32。感光区域可以位于第一面31的中心位置，或者偏心位置，在此不做限制。本实施方式中，第二面33上设置有多个电连接件332，第二面33通过焊接等方式与电路板(图未示)机械连接，多个电连接件332用于实现电路板及色温传感器30的电连接。
需要说明的是，闪光灯20与色温传感器30可以是安装在同一个电路板上使得集成度更高，也可以是安装在不同的电路板以使得模组设计更加灵活。
请参阅图11至图14，在某些实施方式中，导光器40包括支架42及至少两个光路改变元件，两个光路改变元件分别为第一光路改变元件44和第二光路改变元件46。
支架42开设有容纳空间420。至少两个光路改变元件(第一光路改变元件44和第二光路改变元件46)设置在容纳空间420内，用于改变光传输路径，以使得光线能在透镜10与第二功能器件30之间传输。
具体地，请结合图15，在某些实施方式中，支架42包括相背的第一端47与第二端48，第一端47开设有与容纳空间420连通的第一缺口472，第二端48开设有与容纳空间420连通的第二缺口482，第一缺口472与第二缺口482位于支架42相背的两侧，第一缺口472与透镜10的第一面12对应，第二缺口482与第二功能器件30对应。
在某些实施方式中，第二功能器件30的一部分伸入第二缺口482，与支架42的一部分相贴合，一方面，能够可以减小Z方向的厚度，从而降低光学模组100的厚度。另一方面，可以保证光线在导光器40与第二功能器件30之间传输，而不会从第二缺口482泄露出而影响附近其他功能器件的正常工作。
在一个例子中，当第二功能器件30为接收器时，第一光路改变元件44设置在支架42的内侧壁422上并将从第一缺口472进入的光线传输至第二光路改变元件46，第二光路改变元件46设置在支架42的内侧壁422上并用于将来自第一光路改变元件44的光线从第二缺口482传输至第二功能器件30。
在另一个例子中，当第二功能器件30为发射器时，第二光路改变元件46设置在支架42的内侧壁422上并用于将从第二缺口482进入的第二功能器件30的光线传输至第一光路改变元件44，第一光路改变元件44设置在支架42的内侧壁422上并将来自第二光路改变元件46的光线从第一缺口472传输至透镜10的微结构122。
其中，在某些实施方式中，第一光路改变元件44和第二光路改变元件46可以是反射镜，也可以是反射棱镜，第一光路改变元件44和第二光路改变元件46利用光的反射传导光线，这样不会影响所传导光线的波段，在第二功能器件30为光学检测类传感器时，例如第二功能器件30为色温传感器时，不会因为色温传感器所接收到的光线的波段改变而影响色温传感器的判断。第一光路改变元件44可以通过设计在支架42的容纳空间420内的放置位置和角度，使光线能最大化的在透镜10与第二功能器件30之间传输，提高光利用率。进一步地，支架42的内侧壁422除设置有第一光路改变元件44和第二光路改变元件46的表面可以涂覆黑色涂料以减少光线的漫反射，从而减小漫反射对第二功能器件30正常工作的造成影响。
请继续参阅图17，当闪光灯20发光时，闪光灯20的发光面22朝向透镜10的微结构122发出光线，光线通过透镜10发射至外界。当外界的光线进入透镜10后，其中一部分光线在通过透镜10的微结构122后折射进入导光器40的第一缺口472。从第一缺口472入射的光线入射到反射镜44上。反射镜44的反射面朝向第一缺口472以一定角度倾斜，确保能接收到透镜10的微结构122出射的并从第一缺口472进入容纳空间420的光线，并能够将接收到的光线反射到反射镜46上。反射镜46的反射 面水平朝向第二缺口482，确保能接收到反射镜44反射的光线，并能够将接收到的光线反射到第二缺口482与色温传感器30对应的区域。反射镜46接收到的光线被反射镜46反射到第二缺口482与色温传感器30对应的区域后，光线的一部分射入到色温传感器30的感光区域32上，被感光区域32接收以实现色温的检测。
本申请的光学模组100将第一功能器件20与透镜10相对设置，并利用导光器40传导透镜10与第二功能器件30之间的光线，实现了第一功能器件20和第二功能器件30共用一个透镜10，减少透镜10的使用数量，相应地，无需在电子设备1000(图17所示)的壳体200(图17所示)上开设多个通孔210(图17所示)，降低电子设备1000的壳体200设计的复杂度。
另外，本实施方式中的闪光灯20可以朝透镜10发射光线，并通过透镜10将光线向外界发射，使发射至外界的光线更加集中，增强补光效果以更好地辅助拍照。导光器40可以将通过透镜10的微结构122折射的来自外界的光线通过反射传导至色温传感器30的感光区域32上，由于避免了折射，使得在容纳空间420内传输时不会改变光线的波长及不同波长的光线的比例，能够使色温传感器30接收到的光线最大程度地还原真实的外界光，从而保证色温检测的准确性。
请参阅图16，在某些实施方式中，光学模组100的导光器40为导光光纤49。导光光纤49包括相背的第一面492及第二面494，导光光纤49的第一面492与微结构122(透镜10的第一面12)相对，导光光纤49的第二面492与第二功能器件30的收发面32相对。
在一个例子中，当第二功能器件30为接收器时，导光光纤49用于将从微结构122出射的光线沿着导光光纤49的第一面492至第二面494的方向传导至第二功能器件30。在另一个例子中，当第二功能器件30为发射器时，导光光纤49用于将来自第二功能器件30的光线沿着导光光纤49的第二面494至第一面492的方向传导至微结构122。
以第二功能器件30为色温传感器30为例，在某些实施方式中，当外界的光线进入透镜10时，其中一部分光线在通过透镜10的微结构122后折射进入导光光纤49的第一面492，光线在导光光纤49内部以一定角度进行全反射，沿着导光光纤49的第一面492至第二面494的方向传导至色温传感器30的感光区域32。
本申请的光学模组100将第一功能器件20与透镜10相对设置，并利用导光器40传导透镜10与第二功能器件30之间的光线，实现了第一功能器件20和第二功能器件30共用一个透镜10，减少透镜10的使用数量，相应地，无需在电子设备1000(图17所示)的壳体200(图17所示)上开设多个通孔210(图17所示)，降低电子设 备1000的壳体200设计的复杂度。
进一步地，导光器40采用导光光纤49，可以将通过透镜10的微结构122折射的来自外界的光线通过全反射即可传导至色温传感器30的感光区域32上，由于避免了折射，使得在容纳空间420内传输时不会改变光线的波长及不同波长的光线的比例，能够使色温传感器30接收到的光线最大程度地还原真实的外界光，从而保证色温检测的准确性。
请参阅图17，本申请还提供一种电子设备1000。电子设备1000可以是手机、平板电脑、智能手表、头显设备等等，在此不做限制。电子设备1000包括上述任意一实施方式的光学模组100和壳体200。光学模组100与壳体200结合。
下面以电子设备1000是手机，第一功能器件20是闪光灯，第二功能器件30是色温传感器为例进行说明。在某些实施方式中，光学模组100设置在壳体200内部，壳体200包括一个通孔210，一个透镜10设置在通孔210内。通孔210与透镜10的尺寸匹配，透镜10的直径越大，则通孔210的直径越大，透镜10的直径越小，则通孔210的直径越小。
请结合图15，在一个例子中，光学模组100与壳体200结合可以使得透镜10位于壳体200的背面，以作为手机的后置元器件使用。当壳体200包括通孔210，通孔210用于安装透镜10。此时，本申请的电子设备1000将第一功能器件20与透镜10相对设置，使所述第一功能器件30与所述透镜10之间能够自由传导光线。本申请的电子设备1000还利用导光器40传导透镜10与第二功能器件30之间的光线，实现了第一功能器件20和第二功能器件30共用一个透镜10，减少透镜10的使用数量，相应地，无需在电子设备1000的壳体200上开设多个通孔210，降低电子设备1000的壳体200设计的复杂度。
请一并参阅图15及图17，在另一个例子中，光学模组100与壳体200结合可以使得透镜10位于壳体200的正面，以作为手机的前置元器件使用。当壳体200包括通孔210，通孔210用于安装透镜10，此时，本申请的电子设备1000将第一功能器件20与透镜10相对设置，并利用导光器40传导透镜10与第二功能器件30之间的光线，实现了第一功能器件20和第二功能器件30共用一个透镜10，减少透镜10的使用数量，相应地，无需在电子设备1000的壳体200上开设多个通孔210，降低电子设备1000的壳体200设计的复杂度。当光学模组100设置在显示屏下方，通孔开设在显示屏上，第一功能器件20和第二功能器件30共用一个透镜10，减少透镜10的使用数量，可以提升显示屏的屏占比。而且，如前所述，光学模组100无需设计一个较大直径的透镜10，即透镜10的直径相较以前的透镜直径较小，能进一步提升显示屏的屏占比。
