下面结合附图，通过具体的实施例及其应用场景对本申请实施例提供的导光柱100进行详细地说明。
如图1至图6所示，根据本发明实施例的导光柱100包括导光本体10和第一遮光体20。
具体而言，导光本体10包括入光面11和出光面12，入光面11和出光面12位于导光本体10的相对两侧，光线从入光面11导入导光本体10并从出光面12导出。第一遮光体20设于导光本体10的第一侧，且第一遮光体20与导光本体10之间配合限定出溢胶槽40。
换言之，参见图1，根据本发明实施例的导光柱100主要由导光本体10和第一遮光体20组成。其中，如图2和图5所示，导光本体10具有入光面11和出光面12，导光柱100可以通过入光面11和出光面12将外界的环境光传导到电子设备中的色温传感器63，完成导光的目的。入光面11和出光面12设置在导光本体10的相对两侧，光线从入光面11导入导光本体10并从出光面12导出，最后可以进入色温传感器63。
第一遮光体20设置在导光本体10的第一侧，第一遮光体20可以遮挡环境光从导光本体10的第一侧进入导光柱100，减少环境光对导光柱100的干扰，保证光线在导光柱100的入光面11和出光面12上传输。第一遮光体20和导光本体10之间形成溢胶槽40，保证点胶过程中的胶水溢到溢胶槽40中，不会溢胶到入光面11，防止胶水遮挡入光面11，提高导光柱100的导光效果。
由此，根据本发明实施例的导光柱100，通过在导光本体10上设置第一遮光体20，可以有效遮挡环境光从导光本体10的第一侧进入导光柱100，保证光线在导光柱100的入光面11和出光面12上传输。同时通过第一遮光体20和导光本体10之间形成溢胶槽40，保证点胶过程中的胶水溢到溢胶槽40中，不会溢胶到入光面11，防止胶水遮挡入光面11，提高导光柱100的导光效果。
根据本发明的一个实施例，第一遮光体20具有点胶面21，点胶面21与入光面11位于导光柱100的同一侧，点胶面21与入光面11之间设有溢胶槽40相邻布置。
也就是说，参见图1至图4，第一遮光体20上具有点胶区域，第一遮光体20上的点胶区域形成点胶面21，点胶面21与入光面11位于导光柱100的同一侧。导光柱100顶部的入光面11和点胶区域之间形成溢胶槽40。通过在点胶面21进行点胶，多余的胶水会溢入溢胶槽40内，防止胶水遮挡入光面11。本申请在导光柱100上设置溢胶槽40，既能实现点胶，又能确保不会溢胶到入光面11。同时，相对于现有技术来说，本申请可以直接将点胶空间放在导光柱100上(现有技术中通常将胶水点在电子设备的壳体61的台阶上)，更能缩窄黑边和杜绝溢胶，保证导光柱100导光效果的同时，还能提高电子设备的整体外观美度。
在本发明的一些具体实施方式中，点胶面21与入光面11之间形成高度差，且溢胶槽40的靠近点胶面21一侧的侧壁高度小于溢胶槽40的靠近入光面11一侧的侧壁高度。
换句话说，参见图2至图4，点胶面21与入光面11之间具有高度差，导光柱100的入光面11的高度大于点胶面21的高度，溢胶槽40的靠近入光面11一侧的侧壁高度大于溢胶槽40的靠近点胶面21一侧的侧壁高度。通过将点胶面21和入光面11之间设置高度差，进一步提高点胶过程溢胶到入光面11的风险。
根据本发明的一个实施例，溢胶槽40的截面形状为开口向上的匚形，入光面11为方形面，溢胶槽40沿入光面11的长度方向延伸。
也就是说，参见图1，溢胶槽40的截面形状大致为开口向上的匚形，导光柱100的入光面11设置成方形面。溢胶槽40可以沿入光面11的长度方向延伸，形成长条形槽体。当然，在本申请中，溢胶槽40的具体形状还可以根据实际需要进行具体设定，只要设置的溢胶槽40能确保不溢胶到入光面11的布置形式，均应落入本申请的保护范围。
根据本发明的一个实施例，导光柱100还包括延伸部50，延伸部50设于导光本体10的第二侧，延伸部50位于入光面11和出光面12之间，且沿导光本体10的第二侧向远离导光本体10的第一侧的方向水平延伸。
换句话说，参见图1，导光柱100还可以包括延伸部50，延伸部50设置在导光本体10的第二侧，导光本体10的第一侧和第二侧可以理解为导光本体10的相对两侧，其中，导光本体10的第一侧朝向溢胶槽40，导光本体10的第二侧背向溢胶槽40。延伸部50大致位于导光本体10的入光面11和出光面12之间，并且延伸部50可以沿导光本体10的第二侧向远离导光本体10的第一侧的方向水平延伸，通过设置延伸部50便于导光柱100在电子设备内的安装。
在本发明的一些具体实施方式中，导光柱100还包括：第二遮光体30，第二遮光体30设于延伸部50上，且第二遮光体30与导光本体10的第二侧连接。
也就是说，参见图1至图4，导光柱100还可以包括第二遮光体30。第二遮光体30设置在延伸部50上，并且第二遮光体30与导光本体10的第二侧连接，以遮挡导光本体10由第二侧进入的环境光。在本申请中，该环境光可以理解为电子设备的屏幕光。通过在导光柱100上设置第一遮光体20和第二遮光体30，可以保证导光柱100除入光面11和出光面12之间可以进行光线传导之外，其他地方无法进行光线传输，防止环境光从导光柱100的其他区域进入，从而对电子设备中的色温传感器63造成干扰。
在本申请的一个实施例中，如图3所示，第一遮光体20和第二遮光体30为双色注塑材料件。也就是说，导光柱100可以采用双色注塑工艺，在导光本体10的两侧形成不透光材质(非透明材质)以包裹住导光本体10的两侧，达到遮光效果，阻挡环境光对导光柱100的干扰。需要说明的是，双色注塑(double-shot molding)是将两种不同颜色的同一种塑料通过两个料筒塑化后，同时或先后经同一个喷嘴进行注塑的操作方法。本申请的导光柱100通过将透明材质和不透光材质(例如，黑色材质)采用双色注塑形成具有透光 性能的导光本体10和不透光性能的第一遮光体20和第二遮光体30，工艺简便的同时，还能保证导光柱100整体结构的完整性。当然，双色注塑工艺的具体原理本领域技术人员是可以理解并且能够实现的，在本申请中不再详细赘述。
导光柱100的点胶面21旁边的溢胶槽40，在点胶的时候，胶水不会溢到导光柱100的入光面11，保证入光面11的清洁。环境光(例如，屏幕的发光)都被导光柱100外面的非透明材质遮挡，不会造成干扰。
根据本发明的一个实施例，第一遮光体20和/或第二遮光体30为黑色涂层。
也就是说，第一遮光体20可以采用黑色涂层，第二遮光体30可以采用黑色涂层，第一遮光体20和第二遮光体30均可以采用黑色涂层。在本申请中，为了实现顶部更窄边框，导光柱100的宽度需要做到更为极致。第一遮光体20和第二遮光体30可以均采用黑色涂层，黑色涂层可以为黑色油漆，通过在导光柱100上出入光面11和出光面12以外的部分喷涂黑色油漆，既能实现导光，也能实现遮光的效果，还可以进一步减少导光柱100的宽度。
当然，在本申请中，导光柱100的入光面11和出光面12，可以通过遮喷的工艺来实现——即喷涂的时候把入光面11和出光面12遮住，其它地方都喷涂。也可以通过全部喷涂，最后把入光面11和出光面12机加工处理掉油墨层。并且在本申请中除了喷涂，也可以用镀的工艺，实现导光柱100的遮光作用。对于本领域技术人员来说，喷涂等工艺的原理是可以理解并且能够实现的，在本申请中不再详细赘述。
在本申请的一个实施例中，导光柱100也可以采用双色注塑和喷涂工艺结合的方式实现遮光的目的。例如，如图1和图2所示，第一遮光体20采用双色注塑形成，第二遮光体30采用喷涂黑色涂层形成。
在本申请的一个实施例中，如图4所示，第二遮光体30可以采用黑色PET贴条(PET：Polyethylene terephthalate的缩写；聚对苯二甲酸类塑料)，黑色PET贴条设置在导光本体10的第二侧，并且可以延伸至延伸部50上。 通过在导光本体10的第二侧加贴黑色PET贴条，就能可以有效挡住环境光，操作非常简便。而第一遮光体20同样可以采用双色注塑或喷涂黑色涂层实现遮光。
总而言之，根据本发明实施例的导光柱100，通过在导光本体10上设置第一遮光体20，可以有效遮挡环境光从导光本体10的第一侧进入导光柱100，保证光线在导光柱100的入光面11和出光面12上传输。同时通过第一遮光体20和导光本体10之间形成溢胶槽40，保证点胶过程中的胶水溢到溢胶槽40中，不会溢胶到入光面11，防止胶水遮挡入光面11，提高导光柱100的导光效果。
根据本申请的第二方面，提供一种电子设备包括壳体61、屏幕组件62、色温传感器63和上述实施例中的导光柱100。
具体地，屏幕组件62设于壳体61上，屏幕组件62和壳体61之间限定出容纳腔。色温传感器63设于容纳腔内。导光柱100设于容纳腔内，且导光柱100位于色温传感器63的上方，导光柱100的入光面11朝向屏幕组件62，导光柱100的出光面12朝向色温传感器63，溢胶槽40靠近壳体61。
也就是说，参见图1至图6，根据本发明实施例的电子设备主要由壳体61、屏幕组件62、色温传感器63和上述实施例中的导光柱100组成。在本申请中，可以以电子设备为手机进行举例说明。屏幕组件62设置在壳体61上，屏幕组件62和壳体61之间形成容纳腔。色温传感器63设置在容纳腔内。导光柱100设置在容纳腔内，并且导光柱100位于色温传感器63的上方，导光柱100的入光面11朝向屏幕组件62，导光柱100的出光面12朝向色温传感器63。光线从导光柱100的入光面11进入，并从出光面12导出至色温传感器63。溢胶槽40靠近壳体61，导光柱100与壳体61连接。
在本申请中，色温传感器63的工作原理：接收环境光，光学信号转换为数字信号，通过手机的芯片运算，调整摄像头拍照时的白平衡。通过在色温传感器63的上方增加导光柱100，环境光穿过屏幕玻璃进入导光柱100，再抵达色温传感器63。导光柱100通过采用双色注塑工艺或喷涂工艺将导光柱 100除入光面11和出光面12以外的区域进行包裹，达到遮光目的，阻挡屏幕光从导光柱100其他区域进入，造成对色温传感器63的干扰。同时通过在导光柱100上设置溢胶槽40，既能实现点胶，又能确保不溢胶到入光面11。
在本申请中，如图5和图6所示，壳体61可以固定主板64和导光柱100，壳体61可以支撑屏幕组件62。屏幕组件62可以采用透明的盖板玻璃，环境光可以穿透到导光柱100。色温传感器63可以焊接在主板64上，主板64是电子设备的芯片载体所在。
在本申请的一个实施例中，色温传感器63焊接在主板64上，主板64固定在壳体61上，导光柱100通过双面胶也固定在壳体61上。光线从外面通过透明盖板(屏幕组件62)进入到导光柱100里面，再抵达色温传感器63内部，完成传导的作用。本申请的电子设备，壳体61的密封点胶(每个手机都需要完整的一圈点胶，确保不进水、不进尘)在导光处，将胶水点在导光柱100上方，并与入光面11中间设计溢胶槽40。相比之前的方案，将胶水点在壳体61的台阶上，该方案可以更好的解决溢胶问题。本申请直接将所有的点胶空间放在导光柱100上，更能缩窄黑边和杜绝溢胶。导光柱100的两侧采用双色注塑的非透光材质包裹达到遮光的效果，顶部的溢胶槽40解决溢胶遮挡入光面11的问题。导光柱100的点胶面21旁边有一个溢胶槽40，点胶的时候，胶水不会溢到导光柱100入光面11，保证入光面11的清洁。屏幕的发光都被导光柱100外面的非透明材质遮挡，不会造成干扰。因此，本申请的电子设备，色温传感器63通过导光柱100导光，实现基本性能。色温传感器63上的导光柱100，通过双色注塑，确保屏幕光对色温不干扰。同时导光柱100上增加溢胶槽40，确保不溢胶到入光面11。
在本申请的一个实施例中，为了实现顶部更窄边框，导光柱100的宽度需要做到更为极致。第一遮光体20和第二遮光体30可以均采用黑色涂层，黑色涂层可以为黑色油漆，通过在导光柱100上出入光面11和出光面12以外的部分喷涂黑色油漆，既能实现导光，也能实现遮光的效果，还可以进一步减少导光柱100的宽度。
当然，在本申请中，导光柱100的入光面11和出光面12，可以通过遮喷的工艺来实现——即喷涂的时候把入光面11和出光面12遮住，其它地方都喷涂。也可以通过全部喷涂，最后把入光面11和出光面12机加工处理掉油墨层。并且在本申请中除了喷涂，也可以用镀的工艺，实现导光柱100的遮光作用。对于本领域技术人员来说，喷涂等工艺的原理是可以理解并且能够实现的，在本申请中不再详细赘述。
在本申请的一个实施例中，通过在导光本体10的第二侧加贴黑色PET贴条，就能可以有效挡住环境光，操作非常简便。而第一遮光体20同样可以采用双色注塑或喷涂黑色涂层实现遮光，更能节省空间，手机的上黑边框可以做更窄，且工艺更加简单。
在本申请中，如图5所示，导光柱100设置在屏幕侧，从上往下装配，导光柱100下方通过双面胶与壳体61粘接固定，可以理解为正装。然后再把胶水点在导光柱100上，实现整个壳体61与玻璃盖板(屏幕组件62)的粘接。
当然，参见图6，本申请也可以采用从主板64侧，从下往上装，可以理解为反装。反装方式不需要将胶水点在导光柱100上，全部点在壳体61上即可。整个点胶的一致性会更好。从下往上装能保证点胶的一致性，且设有溢胶槽40，能很好的实现上述功能。本申请的电子设备除了正装和反装以外，还可以将导光柱100斜着插进去，可根据具体的整机方案自行设计，只要能保证上述功能的安装式均可。
本申请的电子设备，可以是手机或其他电子产品。并且本申请不仅是色温传感器63可以采用此方案，其它的光学元器件同样可以，如红外传感器，光敏传感器都可以。
总而言之，根据本发明实施例的电子设备，能够有效减小黑边宽度，导光柱100可以通过采用双色注塑工艺或喷涂工艺将导光柱100除入光面11和出光面12以外的区域进行包裹，达到遮光目的，阻挡屏幕光从导光柱100其他区域进入，造成对色温传感器63的干扰。同时通过在导光柱100上设置溢 胶槽40，既能实现点胶，又能确保不溢胶到入光面11。
在本说明书的描述中，参考术语“一个实施例”、“一些实施例”、“示意性实施例”、“示例”、“具体示例”、或“一些示例”等的描述意指结合该实施例或示例描述的具体特征、结构、材料或者特点包含于本发明的至少一个实施例或示例中。在本说明书中，对上述术语的示意性表述不一定指的是相同的实施例或示例。而且，描述的具体特征、结构、材料或者特点可以在任何的一个或多个实施例或示例中以合适的方式结合。
