为了说明本申请所提供的技术方案，以下结合具体附图及实施例进行详细说明。
太阳发出电磁波传播到地球，经过地球大气层的散射形成了蓝天白云的散射光，透过大气层形成了明亮的直照阳光。阳光是一种基本的自然元素，阳光的光谱丰富，有利于人眼的视觉。阳光的日升日落的周期性变化，形成了日出而作、日落而息的自然作息规律。阳光作为一种基本的自然元素，对人的生活有着重要影响。因此，模拟阳光照明，一直是照明行业的一个重大课题。
现有的模拟阳光照明的方式主要有两种，一种方式是使用面板灯，在面板灯的表面印上蓝天白云来模拟自然光的情景，此种方式只模拟了静态的天空，而天空的动态部分，直照阳光部分都没有体现；另一种方式是使用全光谱的LED光源，来模拟阳光的光谱，此种方式只模拟了阳光的光谱，但蓝天白云、直照阳光都没有体现。
可见，现有技术中并没有一种兼具照明和模拟动态场景和环境的照明结构，故，本申请的一些实施例提供一种照明模组，本照明模组主要应用于天花灯技术领域，有嵌入式、吸顶式以及吊装等应用方式，请参阅图1-3所示，照明模组至少包括直照模块3和背光模块5；直照模块3能够发出用于照明的光线，用于模拟阳光；背光模块5包括发光结构，发光结构能够发光并显示模拟画面，模拟画面至少包括动态画面；其中，直照模块3发出的光线从背光模块5前侧射出，以使得直照模块的出射光线与背光模块的出射光线均朝向待照射区域。
在本实施方式中，背光模块5能够发光并显示模拟画面，模拟画面至少包括动态画面，动态画面可以是模拟天空的蓝天白云，还可以是地球不同地区、不同季节或一天不同时段的阳光光色周期性变化的模拟画面等；直照模块3主要用于照明，直照模块3发出光线，能够模拟太阳光，最重要的是直照模块3发出的光线能够从背光模块5前侧（发光侧）射出，可见，本照明模组能够将画面模拟与照明结合在一起，既能够模拟动态的场景、环境，又能够进行照明，适用范围更广。
如图1和图2所示，背光模块5包括阵列排布的多个第一LED光源，多个第一LED光源组合在一起形成LED屏幕，能够显示静态或动态画面，采用第一LED光源能够使图像显示的更加清晰；直照模块3包括至少一个第二LED光源301。
具体地，第一LED光源包括多个LED灯珠，一颗LED灯珠封装至少一种颜色的发光芯片。在一颗LED灯珠发一种颜色的光时，多种（2种及以上）不同发光颜色的LED灯珠组成一个像素点，像素点通过亮度、颜色的变化组成不同的图像；在一颗LED灯珠封装多种不同颜色的发光芯片（2种及以上）时，一颗可发出多种颜色光的LED灯珠为一个像素点，像素点通过亮度、颜色的变化组成不同的图像。
在一个实施例中，一颗LED灯珠可以封装红、绿、蓝三种芯片中的一种或多种的组合，或者使用背光模块5使用红、绿、蓝三种LED灯珠；第一LED光源封装红、绿、蓝三种发光芯片中的一种或一种以上的组合时，通过使用荧光粉来调制发光的光谱，使第一LED光源形成更加丰富的色彩表现。
在一个实施例中，一颗LED灯珠封装蓝光或紫外发光芯片，调制光谱为：色温为5000K-6500K或2500K-3000K或1900K-2500K或15000K-100000K；光谱为380-780nm的连续光谱。
以下以模拟动态蓝天白云的场景举例，说明直照模块3和背光模块5的结构和参数设计。
光是一种电磁波，光谱是光在不同波段上的能量分布。在照明上，是光品质的一种体现，人眼在进化的过程中，适应了阳光的光谱，所以阳光光谱的光品质最好。其他人造光源和阳光进行对比来反映人造光源的光品质。本方案的直照模块3采用模拟阳光光谱的第二LED光源301，在5700K、2700K、2200K都模拟对应色温的阳光光谱。背光模块5采用连续光谱的第一LED光源，在5700K、2700K、2200K、20000K都采用连续光谱，能够拥有丰富的显示效果，同时也满足照明的光品质。
具体地，实施例一，背光模块5的第一LED光源中的LED灯珠封装蓝光或紫外发光芯片，并使用多种荧光粉来调制发光的光谱，色温为5000K-6500K，光谱为380-780nm的连续光谱。
实施例二，背光模块5的第一LED光源封装蓝光或紫外发光芯片，并使用多种荧光粉来调制发光的光谱，色温为2500K-3000K，光谱为380-780nm的连续光谱。
实施例三，背光模块5的第一LED光源封装蓝光或紫外发光芯片，并使用多种荧光粉来调制发光的光谱，色温为1900K-2500K，光谱为380-780nm的连续光谱。
实施例四，背光模块5的第一LED光源封装蓝光或紫外发光芯片，并使用多种荧光粉来调制发光的光谱，色温为15000K-100000K，光谱为380-780nm的连续光谱。
具体地，背光模块5采用多种不同色温的第一LED光源来模拟不同时段的天空，5700K色温为正午白云的颜色，2700K色温接近傍晚白云的颜色，2200K色温接近夕阳落下时白云的颜色，20000K为正午天空的天蓝色。通过不同颜色的组合呈现天空色彩的动态变化。直照模块3采用两种不同色温的阳光光谱的第二LED光源301，5700K色温的光为正午阳光的颜色，2700K色温的光接近傍晚阳光的颜色，通过不同色温的阳光光谱的第二LED光源301来呈现一天之中阳光不同时段的颜色。
在一个实施例中，参照图1和图2所示，第一LED光源的前侧设有雾面膜6，第一LED光源发出的光线通过雾面膜6。
在本实施方式中，背光模块5的像素点组成的图像通过雾面膜6扩散后，图像效果能够更加均匀显示。
在一个实施例中，参照图1和图2所示，照明模组还包括播放模块1；播放模块1与背光模块5电连接，用于为背光模块5提供图像解析，播放装置可以输入图像或视频素材，并解析到阵列显示的多个第一LED光源，显示出对应的模拟画面（图像或视频）；当输入蓝天白云素材时即可以显示蓝天白云。
另外，参照图1和图2所示，照明模组还包括驱动电源2；驱动电源2分别与直照模块3和背光模块5电连接，驱动电源2为第二LED光源301提供驱动，驱动电源2为恒流电源；驱动电源2还可以为第一LED光源提供分路驱动，驱动电源2包括电源模块、信号接收模块和解析模块，信号接收模块能够通过有线或无线方式接收外界的控制信号，并通过解析模块解析控制信号形成对背光模块5和照射模块不同的分路电信号，以驱动背光模块5和直照模块3。
在一个实施例中，参照图1和图2所示，直照模块3除了包括至少一个第二LED光源301外，还包括出光结构7，出光结构7能够使第二LED光源301发出的光线和背光模块5发出的光线通过出光结构7，以形成具有预设出光角度的光束；出光结构7为表面设有微结构的且透明的基板结构，微结构和基板结构均采用透明材料制备，具体的，出光结构7为透明薄板结构，在透明的基材上，形成透明的微结构，光线通过透明的微结构，根据折射、全反射原理，可以形成预设出光角度，第二LED光源301发出的光通过出光结构7，以形成具有一定出光角度的光束；背光模块5位于出光结构7的后方，背光模块5发出的光能够通过出光结构7，对光路进行调整后，形成大面积的光束效果，像从上而下的天光效果。
在本实施方式中，直照模块3采用第二LED光源301，第二LED光源301发出的光通过出光结构7上的微结构后出光角度发生变化，光路被微结构调整后，会形成大面积的光束效果，从上而下的射出形成模拟阳光，达到照明的效果；另外，背光模块5位于出光结构7的后方，背光模块5发出的光同样能够穿透出光结构7，透过出光结构7能够看到背光模块5的显示图像，通过改变背光模块5的动态画面，形成各种模拟的场景环境。本照明模组兼具了照明和环境模拟的功能，适用性更广，能够提高用户的体验感。
具体地，微结构的截面形状可以为三角形、圆形、圆弧形或非对称形等。通过设计不同截面形状的微结构，能够使光线通过出光结构7后形成多种出光角度，以形成不同的照射范围，应用范围更广。
在一个实施例中，第二LED光源301设有多个，多个第二LED光源301沿背光模块5的单边或多边进行线性阵列布置，有利于提高光照强度。
在一个实施例中，参照图1和图2所示，直照模块3还包括位于出光结构7和每个第二LED光源301之间的光学结构，光学结构与第二LED光源301的数量一致，且二者一一对应设置；光学结构包括位于单个第二LED光源301前侧的聚光结构302，聚光结构302与第二LED光源301的数量一致，且二者一一对应设置，聚光结构302可以采用聚光透镜或聚光反光器304，第二LED光源301发出的光线能够通过聚光结构302进行汇聚，减少散射，减少光损失。
在一个实施例中，参照图1和图2所示，光学结构包括至少一个反光器304，第二LED光源301发出的光线经过对应的反光器304反射后通过出光结构7射出。
在本实施方式中，反光器304可以采用反光镜，反光器304的作用是对照射在反光器304的光进行反射，从而改变光的路线；在直照模块3不设置反光器304的情况下，第二LED光源301位于背光模块5的侧部，且第二LED光源301发出的光线至少部分从背光模块5的发光侧射出，发光侧即为背光模块5的前侧，并通过出光结构7发射出去；当直照模块3设置反光器304后，第二LED光源301能够设置在背光模块5的后侧部，光线经反光器304反射后从背光模块5的前侧并通过出光结构7发出。上述结构设计，使得直照模块3的结构更加多样化，以适应不同结构、形状的外壳体4结构，适用范围更强。
具体地，一组光学结构中反光器304设有两个，两个反光器304呈夹角布置，反光器304的反光面面对面设置，单个第二LED光源301发出的光线依次经过对应的两个反光器304后通过出光结构7射出。
在本实施方式中，为了描述方便，两个反光器304分别称作第一反光器3041和第二反光器3042，第二LED光源301能够位于背光模块5的后方，第一反光器3041位于第二LED光源出光方向的前方，并与出光方向成预定角度设置，具体30°-60°，第二反光器3042位于第一反光器3041的侧部，第二反光器3042与第一反光器3041的连线方向与第二LED光源301的出光方向垂直，具体第二反光器3042的反光面与第一反光器3041的反光面之间的夹角为60°-120°，第二反光器3042反射光线至出光结构7去，通过出光结构7射出。
在一个实施例中，参照图1和图2所示，直照模块3还包括滤光结构303，滤光结构303用于对第二LED光源301发出的光线进行滤光，滤光结构303与第二LED光源301的数量一致，且二者一一对应设置。
在本实施方式中，滤光结构303可以内置于第二LED光源301内，使第二LED光源301本身具有滤光的功能，起到滤除杂散光的效果；在滤光结构303设置在第二LED光源301的外部时，滤光结构303包括滤光筒，滤光筒位于第二LED光源301的前侧，经聚光结构302汇聚的光线再通过滤光筒滤除杂散光，进而再通过两个反光器304准直和调整光路到出光结构7，通过出光结构7上的微结构调整出射方向后射出。
在一个实施例中，直照模块3包括多个第二LED光源301、聚光结构302、滤光结构303和反光器304，第二LED光源301、聚光结构302、滤光结构303和反光器304的数量一致，且第二LED光源301、聚光结构302、滤光结构303和反光器304均一一对应设置，多个直照模块3中的第二LED光源301、聚光结构302、滤光结构303和反光器304可以沿背光模块5的一条边进行线性阵列布置，也可以沿背光模块5的多条边进行线性阵列布置，此时，多个第二LED光源301发出的光线与第一LED光源发出的光线均通过出光结构7后形成具有预设出光角度的光束。上述布置方式有利于提高光照强度。
本申请的第二目的在于提供一种照明装置，参照图3所示，照明装置包括上述的照明模组。
在本实施方式中，照明模组的数量主要依据对照明装置的光照强度要求、照明装置的外部结构特点以及模拟场景等的要求进行设计。本照明装置能够将画面模拟与照明结合在一起，既能够模拟动态的场景、环境，又能够进行照明，适用范围更广，提高用户体验感。
在一个实施例中，参照图3所示，照明装置还包括设有出光口的外壳体4，照明模组安装于外壳体4上，直照模块3发出的光线和背光模块5发出的光线通过具有微结构的出光结构7后从出光口射出。
在本实施方式中，外壳体4为具有一定高度的筒壳结构，筒壳结构的横截面外轮廓可以为矩形、圆形或多边形等，可依据用户的需求进行定制，有利于提高用户体验感；另外，外壳体4的出光口形状可为矩形、圆形或多边形等，同样可依据需求进行设计。
因此，可见，本照明装置使用阵列排布的多个第一LED光源来模拟动态情景，使用直照模块3来模拟直照阳光，使用多种荧光粉组合的LED封装技术来模拟阳光的光谱，使用结合地球经度与纬度的算法来模拟不同地区、不同季节，一天之中不同时段阳光光色的周期性变化，本照明装置能够将画面模拟与照明结合在一起，既能够模拟动态的场景、环境，又能够进行照明，适用范围更广。
以上所述仅为本申请的较佳实施例而已，仅具体描述了本申请的技术原理，这些描述只是为了解释本申请的原理，不能以任何方式解释为对本申请保护范围的限制。基于此处解释，凡在本申请的精神和原则之内所作的任何修改、等同替换和改进，及本领域的技术人员不需要付出创造性的劳动即可联想到本申请的其他具体实施方式，均应包含在本申请的保护范围之内。
