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。
请参阅图1-3所示，为本申请一优选实施例的灯具100，包括面发光装置200、侧发光装置300以及投影系统400，面发光装置200配置为模拟自然界中不同时段的太阳光，侧发光装置300围设在面发光装置200的外侧，侧发光装置300配置为模拟阳光照射在天窗边缘的效果，另外，侧发光装置300还能够在面发光装置200中形成虚像303，投影系统400设置在侧发光装置300的侧边，配置为在地面或墙面上形成光斑。
灯具100包括壳体600，壳体600包括底壁610和自底壁610向远离底壁610方向延伸的边框620，在底壁610和边框620之间形成有出光口，面发光装置200的第一出光面201设置在出光口处，面发光装置200包括第一发光模组210和扩散结构220，第一发光模组210与底壁610固定连接，第一发光模组210配置为向扩散结构220发射光线，扩散结构220安装于边框620中，且扩散结构220覆盖第一发光模组210，扩散结构220配置为将第一发光模组210发出的光进行均光。
在一可选实施例中，面发光装置200为吸顶灯，包括底盘、面罩，第一发光模组210，第一发光模组210为可以模拟日光光谱的全光谱LED芯片。在其他实施例中，第一发光模组210也可以为常规的白光光源，通过在面发光装置200的扩散结构220中加入纳米颗粒，以形成瑞利散射，使得第一出光面201呈现出如天空一般的蓝色。本申请对此不予限制。
请参阅图2-5所示，在本申请一较佳实施例中，面发光装置200包括第一发光模组210和扩散结构220。第一发光模组210包括第一基板211和若干个发光模块212，第一基板211与底壁610固定连接，发光模块212安装于第一基板211背离底壁610的一侧，并通过第一基板211电性连接。
发光模块212包括至少两种发光单元，至少两种发光单元能够发出至少两种光谱的光线。至少两种发光单元交错分布，并且相邻的同种发光单元之间颠倒分布，发光单元均为双碗灯珠，即包括两种不同颜色的发光元件。
请参阅图5所示，在一优选实施例中，第一发光模组210上的每个发光模块212均包括第一发光单元2121和第二发光单元2122，其中，第一发光单元2121和第二发光单元2122交错分布，并且，相邻两个第一发光单元2121/第二发光单元2122颠倒分布。其中，第一发光单元2121包括四种不同颜色的发光元件中的任意两种，第二发光单元2122包括四种不同颜色的发光元件中剩余两种颜色的发光元件。单个发光模组中从左向右依次是第一发光单元2121、第二发光单元2122、第一发光单元2121和第二发光单元2122。第一发光单元2121和第二发光单元2122这两个不同种的发光单元交错分布，而相邻的第一发光单元2121或第二发光单元2122则是颠倒分布。通过这四种不同颜色的发光元件，能够实现不同的灯光效果，而将不同种的发光单元交错分布以及同种的发光单元颠倒分布，则使得面发光装置200发出的光色更为均匀，能够模拟不同时间下的太阳光的颜色，实现了光线的动态效果。
在本实施例中，每个发光模块包括两个第一发光单元2121和两个第二发光单元2122，在其他实施例中，发光模块212中包含的第一发光单元2121和第二发光单元2122的数量也可更多，本申请对此不作限制。
在发光模块的发光单元上还套有光源透镜(未图示)，在本实施例中，每个发光单元上均安装有光源透镜，即，光源透镜和发光单元一一对应设置。如此设置，可以让发光单元发射的光线集中到光源透镜的正中央后向外射出，避免光线相互之间的干扰。在其他的实施例中，光源透镜也可为二合一、四合一等多合一透镜，以使单个光源透镜可以覆盖更多的发光单元，或者可以为一个覆盖整个发光单元的光源透镜，这样可以减少光源透镜的数量，生产组装更为方便快捷。
在本实施例中，发光单元在第一基板211上呈圆形排布。具体的，呈多圈同心圆的方式排布，且每圈的发光单元的数目为6或者7或者8的倍数，依据发光单元的电压以及驱动电源的电压确认每圈同心圆中发光单元的数量，本实施例中，灯珠422的电压为3V，驱动电源的电压为24V，故采用串8的模式，即每圈同心圆中发光单元的数量为8的倍数。
在本实施例中，第一基板211上共有Ri圈发光单元，其中i≥2，第R1圈的发光单元的数量为N，第R2圈的发光单元数量为2N，第Ri圈的发光单元数量为i*N，假设第R1圈为1串，标记为1_1，R2圈为2串，标记为2_1和2_2，以此类推，第Ri圈标记为i_1至i_i，则共有i*(i+1)*(i+2)/6串，相当于可以调整i*(i+1)*(i+2)/6串画束，由于具有四种不同颜色的发光元件，所以可以对4*i*(i+1)*(i+2)/6个区域进行各种颜色、亮度的调整，通过控制系统对各个不同区域的发光单元的功率进行精准控制，可以实现从早晨到夜晚的光线的连续性的变化。
在其他实施例中，发光单元在第一基板211上也可呈回字形等其他形状分布，本申请对此不作限制。
面发光装置200还包括内框250和扩散结构220，内框250套设于边框620中，扩散结构220与内框250远离第一发光模组210的一端固定连接。第一发光模组210中的发光单元发出的光经过扩散结构220，扩散结构220对光线进行漫射，将线光源或点光源分不成均匀的面光源。在本实施例中，扩散结构220为扩散板，扩散板的透过率达到40％-65％，扩散板的厚度在3mm左右。
扩散板可以较好的消除第一发光模组210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。
在其他的一些实施例中，扩散结构220也可为微细结构的结构件，微细结构的结构件同样覆盖发光模组，微细结构的结构件也能够起到较好的均光作用，本申请对此不作限制。
在一些实施例中，面发光装置200还包括透明板240，透明板240与内框250远离第一发光模组210的一端固定连接，且透明板240位于第一出光面201背离第一发光模组210的一侧，透明板240背离第一出光面201的一侧为镜面，侧发光装置300发射出的光线至少部分经第二出光面301后投射到透明板240上，并被透明板240反射，形成与第二出光面301的形状相匹配的虚像303，以模拟窗户的一侧被阳光照亮时，在窗户上形成的窗影效果，使得人眼看上去，具有深邃感与通透性。
透明板240的镜面对光线的反射率大于对光线的透过率，从而可以限制外部的光线从出光面入射到透明板240中。可选地，透明板240的材料可以为无机材料，无机材料可以为石英玻璃。透明板240也可以为PMMA、PC等材料，本申请对此不作限制。
在一些实施例中，在透明板240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，在其他实施例中，透明板240可以根据实际情况进行选择，此处不做限制。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，利用反射率高于透过率来实现单向透视的效果。
通过控制不同区域的发光单元的亮度变化，即可实现晨晖、晚霞等不同模式的灯光效果。
侧发光装置300与灯具100可拆卸连接，侧发光装置300设置在边框620与面发光装置200之间，并环绕面发光装置200的第一出光面201设置，侧发光装置300沿第一发光模组210的光线出射方向延伸，侧发光装置300具有贴附于所述边框620靠近第一出光面201一侧的第二出光面301，侧发光装置300还包括第二发光模组310，第二发光模组310在水平方向上位于第二出光面301与边框620之间，第二发光模组310发射出的光线经过第二出光面301后，朝向背离边框620的方向射出。侧发光装置300与常规的氛围灯的发光方式并不相同，侧发光装置300仅向灯具100的内侧发光，在本实施例中，边框620为不透光材质，从而营造出一种阳光射入，照亮窗户的窗沿，从视觉上形成一种透光窗口的效果。
侧发光装置300还包括非出光面302，非出光面302同样背离边框620设置，且非出光面302与第二出光面301之间形成光/影过渡区304。如图14所示，以模拟阳光从一侧射入时，照亮窗户的一侧，而在窗户另一侧形成暗面，使得显示效果更为逼真，第二出光面301与非出光面302环向连接，并共同环绕第一出光面201的外周形成环形面，光/影过渡区304位于第二出光面301与非出光面302的相接处，光/影过渡区304其作用是在第二出光面301与非出光面302之间形成的一个明暗交界区域，可以是一个由亮到暗的连续变化的区域，也可以是一条明显的分界线。
侧发光装置300包括环绕第一出光面201的第二基板311和设置在第二基板311上的发光件312，发光件312通过第二基板311电性连接，第二基板311包括靠近第二出光面301设置的发光区域和远离第二出光面301设置的非发光区域，以在第一出光面201的外周形成被照亮的第二出光面301和不被照亮的非出光面302，在第二基板311的发光区域上设有发光件312，非发光区域则可不设置发光件312。
每个发光件312为LED灯珠和双碗灯珠的一种，或者两者的组合。
在一些实施例中，侧发光装置300还包括背离第二出光面301的遮光件324，第二发光模组310和遮光件324共同围绕在第一出光面201靠近边框620的一侧，以在第一出光面201的外周形成被照亮的第二出光面301和不被照亮的非出光面302。
侧发光装置300可整体设置为相对面发光装置200发生旋转移动，通过在灯具100内设置的微电机以驱动侧发光装置300进行旋转，以更好的模拟太阳东升西落的效果。
以下通过三个具体实施例对侧发光装置300进行说明，但不应以此为限。
实施例一
如图2-3及图6所示，在本实施例中，第二发光模组310的光线发射方向与第一发光模组210的光线发射方向相同，侧发光装置300包括第二发光模组310和导光组件320，导光组件320包括配光件322和出光件321，配光件322设置于第二发光模组310下方，第二发光模组310朝向配光件322发射光线(即第二发光模组310为直下式发光)，配光件322配置为将第二发光模组310中发射出的光线进行折射，出光件321位于配光件322背离边框620的一侧，经配光件322的折射后，从配光件322中出射出的光线再经由出光件321朝向背离边框620的一侧射出。配光件322能够控制光线的出射角度，使得光线以小角度射出，映射距离远，具备更强的通透性。
出光件321朝向第一出光面201的一侧具有白色漫反射表面，以增强虚像303的可见性。
在其他的一些实施例中，第二发光模组310发射出的光线也可竖直向上射入导光组件320中，本申请对此不作限制。
如图6所示，第二发光模组310包括第二基板311和安装于第二基板311上部分区域的发光件312，在第二发光模组310上的发光件312向外发射光线时，导光组件320中与第二基板311上的发光件312对应的区域呈亮光状态(即侧发光装置300的第二出光面301)，导光组件320上未与第二基板311上的发光件312对应的区域则呈阴暗状态(即侧发光装置300的非出光面302)，以模拟太阳光透过窗户向室内照射时将窗户一侧的边缘照亮的效果。
在其他的一些实施例中，也可在第二基板311上的所有区域都安装有发光件312，各个发光件312均可被单独控制，通过控制不同区域的发光件312工作状态，点亮不同位置实现光源的变化，可以实现出光件321上的亮光区域和阴暗区域的转换，模拟实现太阳光在一天中不同时间段以不同角度照射在天窗边缘的效果，实现日升日落。在本实施例中，边框620为半透光或透光材质，通过控制不同区域的发光件312的发光颜色不同，透过边框620能够形成彩虹效果，提升该灯具100的视觉体验。
在一些实施例中，配光件322和出光件321上均具有微细结构。
优选的，配光件322和出光件321的材料为PMMA、PC等透明光学材料。
经过配光件322后射出的光线会经过出光件321，出光件321能够消除第二发光模组310所发射出的光线的颗粒感，同时经过出光件321后射出的光线会更加均匀。
在配光件322远离出光件321的一侧贴附有反射件323，以将射向该区域的光线反射回去，使得光线均朝向出光件321的方向射出，提高光的聚集性。
在出光件321上未被配光件322覆盖的部分，覆盖有遮光件324，通过此处设置的遮光件324，可以避免光线从出光件321上的该部分区域漏射出，遮光件324配置为形成侧发光装置300的非出光面302，以保证出光件321上的该部分区域处于阴暗状态，模拟真实的阳光照射在窗户边缘或天窗边缘的效果。
在其他的一些实施例中，遮光件324可以围绕配光件322进行旋转，当第二基板311上的所有区域都安装有发光件312时，通过旋转遮光件324，以实现在出光件321上亮光区域和阴暗区域的变化。
遮光件324的高度可根据实际情况进行调整，通过微电机配合设置的弹性件进行调整。
实施例二
如图7-8所示，在本实施例中，第二发光模组310’的光线发射方向与第一发光模组210的光线发射方向相交，侧发光装置300包括出光件321，出光件321设置在边框620与第一出光面201之间，并沿边框620的延伸方向超出第一出光面201，第二发光模组310’设置在出光件321朝向边框620的一侧，第二发光模组310’包括呈环形的第二基板311’以及安装在基板内侧的发光件312，第二发光模组310’朝向出光件321的方向发射光线，发射出的光线直接从出光件321的侧面射入出光件321中。
侧发光装置300’还包括环形透镜325，环形透镜325位于出光件321和第二发光模组310’之间，环形透镜325与第二基板311’的内侧连接并覆盖发光件312，发光件312发射出的光线入射到环形透镜325的入光面，在入光面发生折射，满足斯涅耳定律的条件下进入环形透镜325内，然后在出光面发生折射，从环形透镜325出射后再经过出光件321实现光线的均匀射出。
在本实施例中，第二基板311’可选用柔性电路板FPC，在其他的实施例中，第二基板311’也可为其他材质。
优选的，出光件321的材料为PMMA、PC等透明光学材料。
在其他的一些实施例中，也可设置为第二基板311’上的全部区域均安装有发光件312，并将第二基板311’分为多个发光区域，每个发光区域包括多个发光件312，各个发光区域可以单独控制照明，通过控制不同发光区域的工作状态，可以实现出光件321上的亮光区域和阴暗区域的转换，模拟实现太阳光在一天中不同时间段以不同角度照射在天窗边缘的效果。
在其他的一些实施例中，当第二基板311’上的全部区域均安装有发光件312时，也可在出光件321上的部分区域贴附有遮光件324，以避免光线从出光件321上的该部分区域漏射出，使得出光件321上的该部分区域处于阴暗状态，模拟真实的阳光照射在窗户边缘或天窗边缘的效果。遮光板可以进行旋转，通过旋转遮光件324实现出光件321上亮光区域的变化，模拟日升日落的效果。
该实施例中的侧发光装置300整体结构更为简化，第二发光模组310’环绕于出光件321外侧，装配更为方便快捷。
实施例三
在本实施例中，侧发光装置300的结构与实施例一的结构基本相同，侧发光装置300仅向背离边框620的一侧发光，导光组件320包括出光件321和配光件322，第二发光模组310与出光件321的一端固定连接，配光件322围设于出光件321外侧，配光件322的上端面覆盖第二发光模组310上的发光件312，不同之处在于，如图9所示，本实施例中的配光件322上设置有V棱镜微细结构3221，该V棱镜微细结构3221位于配光件322远离第二发光模组310的区域，出光件321为倒V棱镜微细结构，光线从发光件312射出后，利用配光件322上的V棱镜微细结构3211破坏其全反射，使得光线以大角度从配光件322上设置有V棱镜微细结构3221的区域出射，从配光件322出射的光进入倒V棱镜微细结构的出光件321，利用倒V棱镜微细结构3221，使得部分光线能够以小角度出射到透明板240上经过反射形成一个透明的第二出光面301的虚像303。
其中，配光件322底部的V棱镜微细结构3221的背光面和迎光面的角度均小于6度，同时，角度随着发光件312与配光件322的入光侧的距离变化而变化，并且V槽的深度也进行变化。小于6度的迎光面，光线从入光侧射入后，从出光面出来的角度为165度～175度的方向，出光侧的V棱镜微细结构3221将光线向中心压缩到30度之内。出来的165度～175度的光通过出光件321上面的倒V棱镜可以实现小角度出射，角度小于10度出射。通过调整迎光面和背光面的角度及V槽的深度可以调整配光件322的出光面的均匀性。
优选的，配光件322中的V棱镜的背光面和迎光面的角度均在0.25度-0.75度之间，出光件321中的倒V棱镜的顶角角度在55度-70度之间。
在配光件322远离出光件321的一侧，覆盖有反射件323，以在配光件322内部对射向该区域的光线进行反射，使得配光件322中的光线均朝向出光件321的方向射出。
如图12所示，灯具100中还设有侧投影装置330，侧投影装置330设于边框620与面发光装置200之间，侧投影装置330配置为投射仿太阳的光斑，侧投影装置330投射的仿太阳光斑射入透明板240的镜面中，在镜面反射后再向外射出，使得在第一出光面201中形成虚拟的太阳光斑，人眼透过透明板240可以看到太阳照射下来的场景，使得灯具100的显示效果更为逼真。使得人眼能够在第一出光面201中看到反射的虚像，使得灯具100的显示效果更为逼真。
灯具100还包括一个或多个反射装置340，反射装置340设置在侧投影装置330的光线出射方向，侧投影装置330投射出的光线经反射装置340反射一次或多次反射后，射入透明板240的镜面中，在本实施例中，反射装置340为反射镜，反射镜可以为平面、球面、非球面或自由曲面，当反射镜为球面或非球面时，可以将侧投影装置330投射来的光斑进行放大或缩小，而呈自由曲面的反射镜不仅可以将光斑进行放大或缩小，同时，还能消除畸变、像散等像差问题，同时还起到改变像距的作用，使人眼看到的太阳更加遥远，增加真实感。
侧投影装置330包括投影灯珠和凸透镜，其中，投影灯珠为多色灯珠，以模拟不同时刻的太阳色温，凸透镜为菲涅尔透镜或复眼透镜，对投影灯珠发射出的光进行聚光并得到均匀的光斑。
灯具100还包括投影系统400，投影系统400设置在边框620与侧发光装置300之间，并至少部分外露于边框620，投影系统400配置为在墙面或地面上投射出仿太阳光斑，包括圆形光斑、椭圆形光斑或者四边形光板等形状，类似太阳光透过窗户产生的投影。
投影系统400包括多个投影装置410，在本实施例中，设有两个投影装置410，两个投影装置410各自通过连接件与灯具100的边框620活动连接，投影装置410可相对边框620进行旋转。如图10-11所示，投影装置410包括发光组件420、镜筒组件450和透镜组件430，发光组件420包括铝基板421和安装于铝基板421上的灯珠422，灯珠422外套设有光阑440，光阑440与铝基板421抵接，光阑440配置为控制灯珠422发射出的光束通过的强度以及形状，光阑440远离灯珠422的一端上连接有第一透镜431，第一透镜431配置为形成光斑，在光阑440和第一透镜431外侧套设有第一镜筒451，第二镜筒452与第一镜筒451远离第一透镜431的一端旋接，第二镜筒452靠近第一镜筒451的一侧中嵌设有第二透镜432，第二镜筒452远离第一镜筒451的一端与第三镜筒453旋接，第三镜筒453中远离第二镜筒452的一端内嵌设有第三透镜433，第二透镜432和第三透镜433配置为进行成像，利用设置的第一镜筒451、第二镜筒452和第三镜筒453实现对焦距的调整。
其中，第一透镜431和第二透镜432为塑胶透镜，第三透镜433为玻璃透镜，塑胶透镜的质量更轻，有益于整体结构的轻质化，而玻璃透镜则能保证更高的透光率。
在本实施例中，灯珠422为LED灯珠，在其他实施例中，也可为其他类型的灯珠，本申请对此不作限制。
如图13所示，投影系统400的投影方向与第二出光面301的方向一致，在该部分区域一侧的墙面上投影出光斑，以模拟真实的阳光照射方向透过窗户在墙面上所产生的投影。
面发光装置灯具100还包括控制系统，通过控制系统控制面发光装置200、侧发光装置300以及投影系统400的运行，实现多种场景的照明效果。
安装系统500包括安装支架，安装支架与底壁610固定连接，灯具100通过安装支架与安装面固定连接。在本实施例中，安装系统500为挂架式结构，在其他实施例中，也可为快接式结构，本申请对此不作限制。
综上所述，本申请的灯具100中的面发光装置200能够模拟类似蓝天，夕阳，晨光及蓝天白云的效果，侧发光装置300则模拟阳光照射在窗户边缘的效果，使得灯具100的灯光效果更为逼真。侧发光装置300还可在其中设置的透明板240上形成虚像303，产生类似阳光照射在窗户或者天窗边缘的窗影效果，从而形成空间感、深邃感和层次感，投影系统400则能够提供类似阳光通过窗户或者天窗投影到地面或墙面上的光斑，并且，光斑的形状根据灯具100的整体形状变化，能够实现多场景的应用。
以上实施例仅用以说明本申请的技术方案而非限制，尽管参照较佳实施例对本申请进行了详细说明，本领域普通技术人员应当理解，可以对本申请的技术方案进行修改或者等同替换，而不脱离本申请技术方案的精神和范围。
