本申请还提供一种电子设备，包括摄像头模组以及上述的呼吸灯模组，所述摄像头模组与所述导光件相对，且所述导光件环绕所述摄像头模组的光轴设置。
结合图1所示，本申请一实施方式的呼吸灯模组10，可以是应用于手机、平板电脑、智能手表等电子设备中。呼吸灯模组10可以用于指示信息，例如， 在电子设备使用过程中出现来电显示、短信提示、充电提示等场景时，呼吸灯模组10能够以闪烁的方式来起到提示效果。
结合图1和图2所示，呼吸灯模组10包括导光件11、光源组件12、第一反射膜13和第二反射膜14。导光件11具有相背设置的第一环形面11a和第二环形面11b，导光件11的第一环形面11a所在一侧开设有凹槽11c。光源组件12的出光部12a至少部分位于凹槽11c内，以便出光部12a出射的光线能够进入导光件11。第一反射膜13设于第一环形面11a，第二反射膜14设于第二环形面11b，以利用第一反射膜13和第二反射膜14对光线的反射，避免光线从第一环形面11a和第二环形面11b出射，继而使得入射至导光件11的光线从导光件11的周侧出射。这样，在电子设备的摄像头模组20对应导光件11设置时，导光件11的光线朝背离摄像头模组20的光轴方向出射，从而有效地降低了发生窜光的几率，且这种结构设置下，能够维持呼吸灯模组10的整体外观美感。
需要说明的是，第二反射膜14在第二环形面11b形成覆盖区域，出光部12a在第二环形面11b上的正投影落入覆盖区域，从而光源组件12发出光线时，第二反射膜14能够对光线起到良好反射效果，避免导光件11在正对光源组件12的位置比其他位置明亮而出现爆点现象。
进一步地，导光件11的周侧设置有聚光部11d，聚光部11d用于对入射至聚光部11d的光线进行汇聚并从导光件11的周侧出射。这样，虽然光源组件12传播到聚光部11d会衰弱，但由于聚光部11d对光线具有聚光效果，避免出现黑影暗点，有效地提高了导光件11周侧各位置出光均匀性。
聚光部11d包括多个锯齿，多个锯齿依次沿导光件11的周侧排列。沿导光件11传播的光线在从聚光部11d出射时，这些锯齿可以对光线起到汇聚效果，使得对应聚光部11d的位置出光明亮，解决了光源组件12所出射的光沿导光件11传播过程中因损耗而出现的光通量下降所导致的偏暗问题。
在一些实施方式中，导光件11开设有至少2个凹槽11c，导光件11的周侧设有至少2个聚光部11d，凹槽11c和聚光部11d交替地沿导光件11的环绕方向设置。凹槽11c处的出光部12a所发出的光线在经导光件11传播至相应的聚光部11d时，聚光部11d能够对光线起到聚光效果，从而防止聚光部11d对应位 置出现黑影和暗点。
进一步地，任意相邻设置的聚光部11d和凹槽11c之间的间隔相等，以提升导光件11出射光线的均匀性，使得呼吸灯模组10出射形成的环形光效更为柔和，不会出现局部爆点或暗点。
需要说明的是，光源组件12所发出的光可以是单色光线，也可以是多色光线。具体地，光源组件12包括LED灯珠，LED灯珠的出光面所在位置形成出光部12a，其中，LED灯珠包括红光LED灯珠121、绿光LED灯珠122或蓝光LED灯珠123中的至少一者。可以理解地，红光LED灯珠121、绿光LED灯珠122和蓝光LED灯珠123分别用于发出红色、绿色和蓝色光线。相应地，在红光LED灯珠121和绿光LED灯同时发光时，便可以获得红色和绿色形成的混合颜色光线；在红光LED灯珠121和蓝光LED灯同时发光时，便可以获得红色和蓝色形成的混合颜色光线，如此，呼吸灯模组10可以发出混色光效，提升表现力。
下面结合图3所示，对两种颜色光线的混色原理加以说明。
如图3所示，当两个光点(即两种颜色的LED灯珠发光的亮点)与人眼连线的夹角θ足够大时，人眼能分辨出这是两个光点。当两个光点与人眼连线的夹角θ足够小时，人眼会把它们看成是同一个点。这个临界的角度称为人眼的最小分辨视角，其值大约为1＇，可理解地，由于1°＝60＇，因此，人眼的最小分辨视角大约为(1/60)°。当两个光点对人眼形成的夹角小于最小分辨视角时，成像就会重叠到一起变成一个点，这个点的颜色就是两个光点颜色的混合。
结合图4所示，呼吸灯模组10还包括灯罩15，灯罩15包括相连接的透光部151和遮光部152，灯罩15覆盖导光件11的第二环形面11b及周侧面11e，并使得透光部151的至少部分与导光件11相对。可理解地，导光件11的周侧面11e为导光件11的位于第一环形面11a和第二环形面11b外周的表面。出光部12a出射光线时，导光件11将光线从周侧射出至透光部151，光线从透光部151的周侧射出。由于导光件11是从周侧出射光线，透光部151也是从周侧出射光线，从而呼吸灯模组10发光时，光线呈现为远离导光件11中心的方式从呼吸灯模组10的周侧出射，因此，光线便不会进入到对应导光件11中心设置 的摄像头模组20，降低了出现窜光的几率。
进一步地，透光部151和遮光部152通过双色注塑成型于一体，如此便可以维持整体结构强度，且便于加工。在一些实施方式中，透光部151采用透明PC1250Z添加1‰的白色钛白粉和1％的T150扩散粉的注塑料，遮光部152采用灰色PC1414添加1％的白色钛白粉的注塑料，从而使得遮光部152具有低透光性。透光部151和遮光部152均采用抽粒料形式，以保证色料一致性。需要说明的是，遮光部152可以是通过前述的材料形成遮光效果，在一些实施方式中，遮光部152也可以是通过贴附遮光膜的方式来达到遮光效果。例如，灯罩15采取透明塑料或透明玻璃制成，在灯罩15的靠近下方且与出光部12a对应的位置贴附遮光膜，从而使得被遮光膜贴附的位置不能透过光线或透过光线的光通量可以忽略不计，继而形成遮光部152。再例如，以在灯罩15上喷涂油墨(如黑色油墨)的方式形成遮光部152。对于遮光部152的形成方式，在此不做限定。
在本申请实施方式中，以凹槽11c内设置有三种不同颜色的LED灯珠为例，结合图4和图5所示，凹槽11c内的这些LED灯珠发出的光线通过导光件11后在呼吸灯模组10的表面(例如灯罩15的外表面)重新相聚成可发光区域P，可理解地，光源组件12距离发光区域P越远，混合颜色的夹角θ就越小。通过仿真效果发现，光源组件12距离发光区域P在5mm以上时，肉眼无法分辨三种不同颜色的LED灯珠的原色，继而达到良好的混色效果。
在一些实施方式中，如图4所示，红光LED灯珠121、绿光LED灯珠122和蓝光LED灯珠123并排设置于凹槽11c内，绿光LED灯珠122和蓝光LED灯珠123分别位于红光LED灯珠121的内侧和外侧，其中，红光LED灯珠121的内侧为指向导光件11的中心的一侧。该实施方式中，把波长较长的绿灯LED灯珠放置内侧，即导光件11的远离灯罩15的地方，从而避免混色光效中偏绿的问题。
在一些实施方式中，导光件11的透光率为40％～60％，厚度为0.65mm～0.75。需要说明的是，该实施方式中，导光件11的材料中加入了重量百分数为9％～11％的扩散粉，从而增加光线在导光件11的折射路径，以进一步加大不同颜色LED灯珠发出的光线之间的混光距离，使得混色效果均匀，不会出现局部偏色的问题。 扩散粉具体可以为LGLD7750，其在导光件11的材料中的重量百分数具体可以是9％、10％或11％。导光件11的主要材料可以为聚碳酸酯，以获得良好的透光效果。例如，导光件11的材料含有帝人PC-L-1225Y，帝人PC-L-1225Y在导光件11的材料中的重量百分数可以为90％。对于导光件11的材料，在此不做赘述。
在一些实施方式中，第一反射膜13的反射率和第二反射膜14的反射率均大于等于80％，第一反射膜13的透光率为0.3％～0.5％，第二反射膜14的透光率为0.2％～0.4％。如此，便可以将第一反射膜13和第二反射膜14的反射率和透光率控制在合适范围内，以利于发乎良好的反射效果，使得进入导光件11的光线最终从导光件11的周侧出射。第一反射膜13和第二反射膜14的材质具体可以为白色PET。在一些实施方式中，第一反射膜13为双面带胶，第二反射膜14为单面带胶，这样便于将第一反射膜13和第二反射膜14分别贴附在第一环形面11a和第二环形面11b。
结合图4所示，第一反射膜13为双面带胶时，在第一反射膜13贴附在第一环形面11a后，可以将光源组件12的电路板12b粘在第一反射膜13的背向导光件11的一侧。可理解地，光源组件12的LED灯珠可以是通过贴片或胶粘等方式设置在电路板上，随着电路板与导光件11相邻，LED灯珠收容在凹槽11c内。
结合图4和图5所示，透光部151开设有第一台阶槽15a和第二台阶槽15b，第一台阶槽15a用于设置第一装饰圈16，第二台阶槽15b用于设置第二装饰圈17，第一装饰圈16与透光部151的顶面密封连接，第二装饰圈17与第二台阶槽15b的台阶面密封连接，从而有效确保呼吸灯模组10的内部的密封性，以利于对位于其内的光源组件12和对应设置的摄像头模组20进行防水和防尘。需要说明的是，导光件11设置于透光部151的背向第二台阶槽15b的一侧，导光件11的内圈与第二装饰圈17的内圈相对应，以便外界的光线能够穿过第二装饰圈17和导光件11，最终进入摄像头模组20。这里需要说明的是，在本申请中，内圈指的是环形结构件的内侧壁形成的圈，外圈指的是环形结构件的外侧壁形成的圈，以导光件11为例，导光件11的内圈为导光件11的中心孔的侧壁所 构成的圈，相应地，导光件11的外圈为导光件11的周侧面11e所围合形成的圈。
第二装饰圈17形成有安装槽17c，安装槽17c用于安装摄像头镜片20a，摄像头镜片20a与摄像头模组20相对，摄像头镜片20a可以起到美化装饰和保护的作用。需要说明的是，摄像头镜片20a可以是通过光学胶与第二装饰圈17相连接，也可以是卡设在安装槽17c内，在此不做限定。
在一些实施方式中，第二装饰圈17包括第一挡壁17a和第二挡壁17b，第一挡壁17a和第二挡壁17b分别位于第二装饰圈17的内圈和外圈，第一挡壁17a抵接于透光部151的内圈，第二挡壁17b抵接于第一装饰圈16的内圈，这种结构设置紧凑，且第二装饰圈17与第一装饰圈16不容易出现松动，呼吸灯模组10的整体结构强调高，抗摔性好。
结合图6和图7所示，本申请的另一实施方式提供了一种包括上述呼吸灯模组10的电子设备100，该电子设备100还包括摄像头模组20，摄像头模组20与导光件11相对，且导光件11环绕摄像头模组20的光轴设置。基于呼吸灯模组10工作时，光线从导光件11的周侧出射，而不会进入摄像头模组20，从而有效降低呼吸灯工作时引起窜光的几率，同时，呼吸灯模组10工作时，可以在摄像头模组20的周围形成环形光效，整体外观美感得到了提升，改善了用户体验。
结合图7和图8所示，在呼吸灯模组10包括灯罩15、第一装饰圈16和第二装饰圈17的实施方式中，第一装饰圈16和第二装饰圈17可以分别通过第一粘胶层18和第二粘胶层19与灯罩15相连接。其中，第一粘胶层18和第二粘胶层19可以是通过胶水固化形成，也可以是采取双面胶带，在此不做限定。
灯罩15的外侧可以是通过胶水粘接或双面胶与电子设备100的壳体(例如后盖101)相连接，从而将呼吸灯模组10整体安装至电子设备100。可理解地，透光部151的出射光线的区域(即可发光区域P)从后盖101和第一装饰圈16之间露出，从而，呼吸灯模组10工作出射光线时，透光部151的周侧形成光环。
在一些实施方式中，灯罩15也可以是与电子设备100的前盖板相连接，导光件11与前置摄像头对应设置，此时，呼吸灯模组10可以在前置摄像头周围 形成环形光效。
结合图9，图9为本申请实施例提供的电子设备100的结构示意图。该电子设备100可以包括射频(RF，Radio Frequency)电路501、包括有一个或一个以上计算机可读存储介质的存储器502、输入单元503、显示单元504、传感器505、音频电路506、无线保真(WiFi，Wireless Fidelity)模块507、包括有一个或者一个以上处理核心的处理器508、以及电源509等部件，本领域技术人员可以理解，图9中示出的电子设备100结构并不构成对电子设备100的限定，可以包括比图示更多或更少的部件，或者组合某些部件，或者不同的部件布置。

无线保真(WiFi)属于短距离无线传输技术，电子设备100通过无线保真模块507可以帮助用户收发电子邮件、浏览网页和访问流式媒体等，它为用户提供了无线的宽带互联网访问。虽然图9示出了无线保真模块507，但是可以理解的是，其并不属于电子设备100的必须构成，完全可以根据需要在不改变发明的本质的范围内而省略。
处理器508是电子设备100的控制中心，利用各种接口和线路连接整个电子设备100的各个部分，通过运行或执行存储在存储器502内的应用程序，以及调用存储在存储器502内的数据，执行电子设备100的各种功能和处理数据，从而对电子设备100进行整体监控。可选的，处理器508可包括一个或多个处理核心；优选的，处理器508可集成应用处理器和调制解调处理器，其中，应用处理器主要处理操作系统、用户界面和应用程序等，调制解调处理器主要处理无线通信。可以理解的是，上述调制解调处理器也可以不集成到处理器508中。
电子设备100还包括给各个部件供电的电源509。优选的，电源509可以通过电源管理系统与处理器508逻辑相连，从而通过电源管理系统实现管理充电、放电、以及功耗管理等功能。电源509还可以包括一个或一个以上的直流或交流电源、再充电系统、电源故障检测电路、电源转换器或者逆变器、电源状态指示器等任意组件。
尽管图9中未示出，电子设备100还可以包括蓝牙模块等，在此不再赘述。具体实施时，以上各个模块可以作为独立的实体来实现，也可以进行任意组合，作为同一或若干个实体来实现，以上各个模块的具体实施可参见前面的方法实施例，在此不再赘述。
以上所述实施例的各技术特征可以进行任意的组合，为使描述简洁，未对上述实施例中的各个技术特征所有可能的组合都进行描述，然而，只要这些技术特征的组合不存在矛盾，都应当认为是本说明书记载的范围。
以上所述实施例仅表达了本申请的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对申请专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本申请构思的前提下，还可以做出若干变形和改进，这些都属于本申请的保护范围。因此，本申请专利的保护范围应以所附权利要求为准。
