具体实施方式
为使本公开的目的、特征、优点能够更加的明显和易懂，下面将结合本公开实施例中的附图，对本公开实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本公开一部分实施例，而非全部实施例。基于本公开中的实施例，本领域技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本公开保护的范围。
本实施例提供一种背光结构，该背光结构可设置于电子设备的边缘，在电子设备使用时，可通过该背光结构向外发出五颜六色的光，以增强氛围感。其中，电子设备可以为台式电脑、电视等的显示屏，也可以是中控屏或者门禁控制屏等，本实施例中以智能家居的壁挂中控屏为例。
在本公开的实施例中，壁挂中控屏的边缘处设置上述背光结构，若该壁挂中控屏为圆形，可在其圆周外侧壁上设置一周该背光结构；若该壁挂中控屏为多边形，则可以在其一条边或者多条边的外侧壁上设置该背光结构。
参照图1-5，在本公开的实施例中，壁挂中控屏具有侧边框5与后盖6，背光结构设置在侧边框5与后盖6内侧，背光结构包括发光灯珠1、灯板2与异形导光条3，异形导光条3沿其延伸方向开设有直槽31，在异形导光条3开设直槽31的一面抵接灯板2后，异形导光条3与侧边框5以及灯板2围合形成一光源空间4，多个发光灯珠1均匀放置于光源空间4内，且发光灯珠1安装在灯板2上。
参照图3-5，异形导光条3包括入光面32与发光面33，在光源空间4内，异形导光条3上朝向灯板2的一面为入光面32，发光面33位于壁挂中控屏的边缘表面，优选的，为了美观，发光面33与壁挂中控 屏的边缘表面相切。
在本公开的实施例中，多个发光灯珠1采用RGB模式的LED灯珠，可实现五彩斑斓的发光效果，可通过调整每颗LED灯珠的间距来实现发光均匀性；多个发光灯珠1也可更换为一条多彩灯带。
在本公开的实施例中，异形导光条3为硬质导光条，成本较低，且发光特性比较好。所以也可以根据异形导光条3材料的雾度与透光度来实现发光均匀性。
在本公开的实施例中，发光面33设置为磨砂哑面，可以使从发光面33发出的光漫反射到墙壁上，更加具有氛围感。
发光灯珠1发射处的光线经过入光面32在异形导光条3中经过折射和反射最终会从发光面33射出，再经过光的漫反射，最终射到墙壁上，可以起到烘托氛围的效果。
参照图5，在本公开的实施例中，侧边框5上连接有一底板7，底板7与后盖6平行，后盖6、异形导光条3、灯板2与底板7按照从上至下的顺序放置，通过螺钉8连接底板7与后盖6，则螺钉8还能够同时穿过异形导光条3与灯板2，在螺钉8拧紧后，异形导光条3与灯板2相互抵紧，从而能够将异形导光条3与灯板2固定在壁挂中控屏内部，达到比较好的固定效果，避免发光灯珠3在使用过程中产生突然的晃动，影响发光效果。
参照图3-5，在本公开的实施例中，异形导光条3包括板状固定部34、发光延伸部35与阶梯连接部36，其中，板状固定部34被夹持于后盖6与灯板2之间；阶梯连接部36连接于发光延伸部35与板状固定部34之间，后盖6的内表面上设置有压板筋61，在后盖6抵紧于阶梯连接部36时，压板筋61能够抵紧于板状固定部34；侧边框5与后盖6之间设置有出光空隙，板状固定部34在被后盖6与灯板2夹持后，发光延伸部35从出光空隙通过，且发光面33分别与后盖6以及侧边框5的外边面相切。
综上，本公开的壁挂中控屏在其侧面增设了背光结构，在背光结构中，灯板上设置多颗发光灯珠，发光灯珠1发出的光通过异形导光条3上设置的入光面32进入异形导光条3内部，再进行折射和散射到达发 光面33，由于发光灯珠1采用RGB模式的LED灯珠，能够发出五彩斑斓的颜色；并且发光面33的光均匀性，能够根据异形导光条3材料的雾度与透光度以及每颗LED灯珠的间距来实现。进一步地，发光面33表面设计成磨砂哑面，发出的光通过漫反射到墙壁上，最终能够实现壁挂中控屏背光的效果，以增强氛围感。
应该理解，可以使用上面所示的各种形式的流程，重新排序、增加或删除步骤。例如，本公开中记载的各步骤可以并行地执行也可以顺序地执行也可以不同的次序执行，只要能够实现本公开公开的技术方案所期望的结果，本文在此不进行限制。
此外，术语“第一”、“第二”仅用于描述目的，而不能理解为指示或暗示相对重要性或者隐含指明所指示的技术特征的数量。由此，限定有“第一”、“第二”的特征可以明示或隐含地包括至少一个该特征。有涉及“第一方向”、“第二方向”等方向性的术语，均代指某直线方向，除非另有明确具体的限定。在本公开的描述中，“多个”的含义是两个或两个以上，除非另有明确具体的限定。
以上所述，仅为本公开的具体实施方式，但本公开的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本公开揭露的技术范围内，可轻易想到变化或替换，都应涵盖在本公开的保护范围之内。因此，本公开的保护范围应以所述权利要求的保护范围为准。
