具体实施方式
为了使本申请的目的、技术方案和优点更加清楚，下面结合附图和具体实施例对本申请进行详细描述。
在此，需要说明的是，为了避免因不必要的细节而模糊了本申请，在附图中仅仅示出了与本申请的方案密切相关的结构和/或处理步骤，而省略了与本申请关系不大的其他细节。
另外，还需要说明的是，术语“包括”、“包含”或者其任何其他变体意在涵盖非排他性的包含，从而使得包括一系列要素的过程、方法、物品或者设备不仅包括那些要素，而且还包括没有明确列出的其他要素，或者是还包括为这种过程、方法、物品或者设备所固有的要素。
请参考图1至图6，本申请提供一种灯具，包括：壳体100、面光源模块200、面光源面罩300、侧光源模块400和侧光源面罩500。
壳体100包括：底盘110和侧边框120。
侧边框120与底盘110相连并环绕设置，底盘110和侧边框120之间形成有容置空间101。
面光源模块200设置于底盘110，且被侧边框120环绕。
面光源面罩300位于容置空间中，并与面光源模块200相对设置。
在本实施例中，面光源面罩300包括：第一扩散板310。
其中，第一扩散板310背向底盘110一侧的表面311为镜面。
第一扩散板310对面光源模块200发出的光线进行漫射，将线光源或点光源分布成均匀的面光源。第一扩散板310可以较好的消除面光源模块200中发射出的光的颗粒感，具有扩散光线的作用，即光线在其表面会发生散射，将光线柔和均匀的散播出来。光线经扩散板扩散之后，照射面积更大，光线均匀度较好，色度稳定。
在一些实施例中，在第一扩散板310的出光面上通过镀晶工艺度镀上一层很薄的单向膜层，如锡，银或者铝等，从而形成单向膜层，采用镀晶工艺可以使单向膜层具有比较高的光滑度，单向膜层的厚度则可根据实际情况进行调整，当单向膜层的厚度增加时，其反射率和透过率会发生改变。
侧光源模块400设置于侧边框120，侧光源模块400环绕第一扩散板310，并且，在灯具的深度方向Z上，侧光源模块400的至少部分光源410与底盘110之间的间距，大于第一扩散板310与底盘110之间的间距。
侧光源面罩500，位于容置空间中，并与侧光源模块400相对，侧光源面罩500环绕面光源面罩300设置。
在本实施例中，如图4中所示，侧光源模块400射出的光线经侧光源面罩500后出射，由于侧光源模块400的至少部分光源410与底盘110之间的间距，大于第一扩散板310与底盘110之间的间距，并且，第一扩散板310背向底盘110一侧的表面311为镜面，因此，经侧光源面罩500后出射的光线中至少部分会入射至表面311后发生菲涅尔反射，在镜面中形成与侧光源面罩500形状相匹配的清晰的侧面光虚像，从而，以简单、低成本的结构，增加了灯具的深邃感，真实的模拟出窗口处窗影的自然光的效果。
在另一实施例中，请参考图6，面光源面罩还包括：透明板320。
透明板320位于第一扩散板310背向底盘110的一侧，透明板320与第一扩散板310贴合固定，并且，透明板320背向底盘110一侧的表面321为镜面。由此，通过双层镜面形成双重倒影，进一步增加灯具的深邃感，窗口处窗影的仿真效果更好，此外，通过在第一扩散板310出光的一侧贴合固定透明板320，也进一步增加人员看面光源面罩时的通透感。
需要说明的是，图6中透明板320与第一扩散板310之间的间隙，是为了示意性的表示透明板320与第一扩散板310非一体成型，因此，即使二者贴合固定，二者之间仍然会有空气。
优选的，面光源模块200的光源的正投影在第一扩散板310的正投影范围内，并且，面光源模块200的光源的正投影在透明板320的正投影范围内。以此更高效地对灯具的光源进行利用。
进一步的，透明板320的材料包括石英玻璃、PMMA或PC。
在一些实施例中，在灯具的深度方向Z上，侧光源模块400的光源410与底盘110之间的最小间距大于或等于第一扩散板310与底盘110之间的间距。由此，提高了侧光源模块400的光源410的利用效率。
在一些实施例中，侧光源模块400的亮度高于面光源模块200的亮度。由此，能够使窗影更为明显，进一步提高仿真的真实感。
进一步的，侧光源模块400的发光颜色与面光源模块200的发光颜色不同。由此，能够使窗影更为明显，更进一步提高仿真的真实感。
在一些实施例中，侧光源面罩500为第二扩散板。从而，类似于第一扩散板300的原理，能够均匀侧光源面罩500的光线。
在一些实施例中，在灯具的深度方向Z上，侧光源面罩500具有相对的顶端和底端，顶端501相比底端502靠近底盘110，并且，顶端501承接面光源面罩300的周缘。由此，面光源面罩300和侧光源面罩500之间无间隔，使得面发光和侧发光的整体性强，模拟真实的自然光效果好。
具体的，侧光源面罩500在顶端501处形成有连接槽，连接槽朝向底盘110和面光源面罩300开口，面光源面罩300搭接于连接槽在灯具的深度方向Z上的槽底，并且，面光源面罩300背向底盘110一侧的表面与槽底接触。由此，以简单的结构实现侧光源面罩500与面光源面罩300的连接，以及面光源面罩300的固定。
在一些实施例中，侧边框120远离底盘110的一端朝向容置空间伸出边框连接部121，侧光源面罩500的底端502抵接于边框连接部121的自由端端末处。由此，实现了对于侧光源面罩500的固定。
在一些实施例中，壳体100还包括：内框130。
内框130套设在侧边框120内侧，并且，内框130位于底盘110与面光源面罩300之间，内框130远离底盘110的一端与面光源面罩300抵接，并且，内框130远离底盘110的一端与面光源面罩300背向底盘110一侧的表面接触。由此，通过内框130进一步对面光源面罩300进行限位固定。
虽然本申请披露如上，但本申请并非限定于此。任何本领域技术人员，在不脱离本申请的精神和范围内，均可作各种更动与修改，因此本申请的保护范围应当以权利要求所限定的范围为准。
