请参阅图1和图2，本申请提供了一种电子设备1000，电子设备1000可以为无人机或者手持云台等手持式运动设备，也可以为智能手机和个人数字助理等通讯设备。电子设备1000包括：设备壳体100和设置于设备壳体100内的发光组件200，设备壳体100上设置有出光口1001，发光组件200包括光源10和导光装置20；
导光装置20包括导光柱21，导光柱21包括入光面201、反射面202及出光面203，入光面201位于导光柱21的其中一侧，并且与光源10正对设置；出光面203位于导光柱21另外一相邻侧，并且与出光口1001正对设置；反射面202与入光面201以及出光面203倾斜相对设置，
其中，反射面202为弧形的凸面，并且由导光柱21凹陷形成；
光源10发出的光线自入光面201进入导光柱21，经反射面202反射后改变方向，从出光面203离开导光柱21，并从出光口1001射出。
本申请提供的电子设备1000，通过设置弧形凸面形状的反射面202，光源10发出的光线抵达反射面202后改变方向并获得较大的出光角度，发散地射向出光面203，可在较小空间内实现侧向于光源10照射方向的出光角度的设计要求，具有较大的外指示出光面积和较优的出光效果。
具体的，导光柱21的材质包括丙烯腈-丁二烯-苯乙烯共聚物、聚碳酸酯、聚甲基丙烯酸甲酯中的一种或者多种，上述材料制成的导光柱21具有良好的导光特性。另外，光源10可嵌入导光柱21的入光面201以保证光源10的绝大部分光线能够被导光柱21捕获，也可以在光源10和导光柱21的入光面201之间设置凸透镜，将光线聚焦至入光面201处，提高导光柱21对光线的捕获率。入光面201与光源10的发光面正对。光源10为LED灯(Light Emitting Diode，LED)，优选为贴片式LED灯，本申请提供的导光柱21配合扁平结构的贴片式LED灯可进一步压缩电子设备1000的内部结构，有利于实现电子设备1000 的紧凑设计要求。导光柱21中可加入扩散剂或者色粉以使得射出的光线分布均匀。
一种实施方式中，请参阅图2，导光柱21还包括第一面204、第二面205、第三面206和第四面207，入光面201、第一面204、第二面205、出光面203、第三面206、反射面202和第四面207依次连接，第四面207远离反射面202的一侧连接至入光面201。第一面204、第二面205、第三面206、第四面207均为平面，入光面201可以为平面，也可以为凹陷形成的凹面。出光面203优选为平面，出光面203与出光口1001具有间隔距离。第二面205与入光面201平行且位于入光面201远离反射面202的一侧，第一面204与入光面201的夹角α为60°-120°。可以理解的是，反射面202为弧形的凸面，由导光柱21凹陷形成，该处的凸面相对光线而言，同理，入光面201可以为凹陷形成的凹面，该处的凹面也是相对光线而言的。通过设置第三面206于出光面203和反射面202之间，避免出光面203和反射面202形成尖角，尖角容易受到破坏，第四面207同理。设置第一面204和第二面205于入光面201和出光面203之间，第二面205与入光面201平行且位于入光面201远离反射面202的一侧，增大出光面203的面积，进一步增大了外指示出光面积。
一种实施方式中，请参阅图2至图3b，导光柱21还包括相对设置的第一连接面208和第二连接面209，第一连接面208与第二连接面209均与入光面201、第一面204、第二面205、出光面203、第三面206、反射面202和第四面207连接，第一连接面208、第二连接面209和第一面204、第二面205、第三面206和第四面207可涂上白色反光涂料以避免光线从第一连接面208和第二连接面209逃逸到空气中造成损耗，而且，在设置多个导光柱21以及多个光源10时，可避免多个光源10之间的干扰，保证灯光指示的准确性。导光柱21整体呈三棱柱的形状。可以理解的是，设置多个光源10时，光源10的光线可能逃逸到其他光源10对应的导光柱21上，以使得其它导光柱21叶导出错误的光线。举例而言，如第一光源正在通过第二导光柱导出红光，而红光表示第一功能故障，而第二光源无导光，表示第二功能未启用，但由于红光在第二导光柱中逸散，进入了第二光源对应的第二导光柱，使得第二导光柱也导出红光，由此用户容易误判第二功能处于故障状态。
一种实施方式中，请参阅图2，入光面201和出光面203之间的夹角α为钝角。具体的，夹角α的值可以为90°、95°、120°、135°和160°等。通过设置入光面201和出光面203之间的夹角α为钝角，以便于实现导光柱21具有侧向于光源10照射方向的出光角度，同时出光面203倾斜于入光面201，具有较大的外指示出光面积。
一种实施方式中，请参阅图2，入光面201的粗糙度小于出光面203的粗糙度。可以理解的是，粗糙度越小，表面越平滑，产生的漫反射越少，光线的损耗越少，因此入光面201采用较低的粗糙度以保证射出光线的强度足够。粗糙度越大，表面越不规则，产生的漫反射越多，光线分布地更为均匀，因此出光面203采用较高的粗糙度以保证射出的光线分布均匀。
一种实施方式中，请参阅图2，入光面201经过打磨处理，出光面203设置有纹理结构。具体的，出光面203可通过加火花纹等手段以获得纹理结构。通过设置经过打磨处理的入光面201以及具有纹理结构的出光面203，以便于入光面201的粗糙度大幅度小于出光面203的粗糙度。
一种实施方式中，请参阅图1和图5，电子设备1000还包括设置于设备壳体100内的 电路板300，光源10和导光柱21均设置于电路板300上。具体的，电路板300可以为印刷电路板300(Printed Circuit Board，PCB)或者柔性电路板300(Flexible Printed Circuit，FPC)，优选为印刷电路板300。可以理解的是，电路板300的光源10可展示电路板300的工作情况，导光柱21可将光源10的光信号发送出去，以便于用户了解电子设备1000的运作状态，有利于电子设备1000的智能化。
一种实施方式中，请参阅图1、图3a和图3b，导光柱21为多个，光源10为多个，多个光源10与多个导光柱21一一对应。具体的，多个导光柱21间隔设置，导光柱21的结构形状均相同。通过设置多个光源10和多个导光柱21一一对应，以便于多个导光柱21分别将对应的光源10的光线导出来。
一种实施方式中，请参阅图1、图3b和图4，出光口1001为多个，多个出光口1001间隔设置，多个出光口1001分别与多个导光柱21中的出光面203一一对应。具体的，多个出光口1001尺寸可以相同，也可以部分不同，出光口1001为通孔状，其截面可以为圆形、方形、圆角矩形等形状，优选为对应出光面203的形状，本实施例中的出光面203呈矩形，因此出光口1001的截面形状优选为圆角矩形或者方形。
一种实施方式中，请参阅图3a和图3b，导光装置20还包括连接件22，相邻的导光柱21通过连接件22固定连接。具体的，连接件22可通过螺纹或者卡扣等连接方式固定相邻的导光柱21。通过设置连接件22固定相邻的导光柱21，以便于多个导光柱21、多个光源10以及多个出光口1001对应，有利于电子设备1000的装配。
一种实施方式中，请参阅图3a和图3b，连接件22与导光柱21一体成型。可以理解的是，一体成型的连接件22和导光柱21结构，便于连接件22和导光柱21批量生产，生产效率较高，且一体成型结构的连接件22和导光柱21组装方便且可以扩展。
一种实施方式中，请参阅图3a、图3b和图7，连接件22包括相互连接的连接部221和第一固定部222，相邻的导光柱21通过连接部221固定连接，第一固定部222自连接部221向电路板300延伸，用于将导光装置20与电路板300连接固定。具体的，第一固定部222可以为螺钉，电路板300设置对应的螺纹以进行螺纹连接而固定。第一固定部222设于连接部221背向出光口1001的一侧，连接部221连接的是相邻的两个导光柱21相对的第一连接面208和第二连接面209。通过设置第一固定部222，连接件22通过第一固定部222与电路板300固定，以便于导光柱21相对电路板300固定。
一种实施方式中，请参阅图1和图7，电路板300开设有安装孔3001，第一固定部222插入安装孔3001，且第一固定部222与电路板300通过热熔的方式固定。可以理解的是，一般将导光柱21固定在电路板300上需要设置支架，支架连接固定电路板300和导光柱21，或者支架连接固定导光柱21和设备壳体100，设备壳体100相对电路板300固定，因此使得导光柱21与电路板300相对固定。不管是哪种支架，其整体结构均较为复杂且占用空间很大，不利于电子设备1000的紧凑设计。通过设置安装孔3001，第一固定部222插入安装孔3001后通过热熔的方式固定，无需设置支架，工艺和结构均较为简单，且占用空间小，固定效果好。
一种实施方式中，请参阅图3a和图3b，连接件22为多个，电路板300上开设有与连接件22一一对应的多个安装孔3001。具体的，优选多个连接件22的结构均相同，安装孔 3001的形状以及尺寸也相同。通过设置多个连接件22以及多个安装孔3001，以便于将多个导光柱21固定于电路板300。
一种实施方式中，请参阅图1和图3a，多个导光柱21和多个连接件22形成的整体结构呈直线延伸，直线平行于电路板300。具体的，多个连接件22和多个导光柱21均设于电路板300的边缘部分，以便于导光柱21导出光源10的光线。通过设置多个连接件22和多个导光柱21形成的整体结构沿直线延伸，合理占用设备壳体100内部空间，以便于优化设备壳体100的外形设计。
一种实施方式中，请参阅图1、图6和图7，发光组件200还包括遮光件30，遮光件30位于相邻的导光柱21之间。具体的，该实施例中导光柱21的第一连接面208和第二连接面209可不涂设白色反光涂料。通过设置遮光件30于导光柱21之间，可简化导光柱21的制造工艺，同时也可避免多个光源10之间的干扰，保证灯光指示的准确性。
一种实施方式中，请参阅图1和图7，遮光件30固定于电路板300。具体的，遮光件30可通过涂胶或者贴双面胶固定于电路板300上，也可通过螺纹连接在电路板300上。通过设置遮光件30固定于电路板300上，进一步将导光柱21以及连接件22的整体结构稳固在电路板300上。
一种实施方式中，请参阅图1，遮光件30的材质为柔性不透明材料。通过设置柔性不透明的遮光件30，与相邻的两个导光柱21密封性较好，进一步避免多个光源10之间的干扰。
一种实施方式中，请参阅图1，遮光件30的材质包括硅橡胶、泡棉中的一种或者两种的组合。具体的，遮光件30可以仅采用泡棉制成，也可以采用硅橡胶和泡棉共同制成，另外也可含有其他成分，由此制成的遮光件30具有较好的遮光效果。
一种实施方式中，请参阅图3a和图3b，连接部221包括镂空结构2211，遮光件30中的至少部分，填充于镂空结构2211。具体的，镂空结构2211的开口朝向电路板300和设备壳体100。通过将遮光件30的至少部分填充于镂空结构2211，使得遮光件30能够相对导光件固定，使得导光件、遮光件30和电路板300两两相互固定，从而提高了电子设备1000的可靠性。
一种实施方式中，请参阅图3a和图7，遮光件30包括遮光部31和第二固定部32，遮光部31填充于镂空结构2211，第二固定部32将遮光件30固定于电路板300。具体的，遮光部31和第二固定部32相互连接，第二固定部32胶合固定于电路板300，遮光部31可与相邻的两个导光柱21相对的第一连接面208和第二连接面209连接。可以理解的是，当导光柱21和连接件22直接用同一材料做成时会发生较大的串光，通过设置遮光部31填充于连接件22的镂空结构2211，可避免串光，使得导光柱21和连接件22可用同一材料制成，进而方便加工和一体成型。
另一种实施方式中，导光柱21和连接件22是不同材料，连接件22采用遮光材料，连接件22不设有镂空结构2211，此时导光柱21两两之间是分体的，这虽不便于一体加工成型，但方便更换老化的导光柱21，且可无需设置遮光件30。
