其中，第一光源采用小发光面大功率的光源，例如，Luminus公司生产的型号为CBT-90-W57H的大功率白光LED灯、COB光源等。
配光元件2可以是TIR透镜，也可以是表面为弧形的透镜，也可以是其他形状的透镜，或其他光学元件，只要是可以实现将点状光源发出的发散光配置为平行光即可。
在本申请的一个具体实施例中，如图2所示为配光元件的剖视图，配光元件2的形状为沿光轴对称，该配光元件2具有第一端面21、与所述第一端面21相对设置的第二端面22以及外表面23，其中外表面23为碗形状。第一端面21为出光面，第二端面22为入光面，外表面23配置为将来自于第二端面22的光导向第一端面21。
第二端面22的具体形状为：第二端面22为自碗底处向内延伸形成凹陷，凹陷的内表面为向光轴轴向弯曲的弧面，所述凹陷沿光轴对称。
在本申请的一个可能的实施方式中，配光元件2配置为对第一光源1的 出射光线进行准直，该配光元件2具有入光面和出光面，其中出光面与所述入光面为非平行设置。
在本申请的一个可能的实施方式中，经过配光元件2配置后从出光面出射的光线与出光面的法线的夹角满足下式的关系：
Figure PCTCN2020126784-appb-000002
其中，I为从配光元件的出光面出射的光线与光轴的夹角；I k为从配光元件的出光面出射的第k条光线与光轴的夹角；n为光线数。
也就是，第一光源1发出的发散光在配光元件2中经过折射、反射后在配光元件2的出光面射出，射出的光线与出光面的法线的夹角小于10°
本申请实施例中，通过设置配光元件使得第一光源在配置元件的出光面的出射光线与出射面的法线的夹角小于10°，尽可能的使得再出光面的出射光线接近准直。
优选的，使得I为0°。
在本申请的一个可能的实施方式中，配光元件2的材料可以采用PC(Polycarbonate，聚碳酸酯)，也可以采用PMMA(polymethyl methacrylate，聚甲基丙烯酸酯)，也可以采用其他材料。
在本申请的一个可能的实施方式中，如图2所示，配光元件2还包括：位于第一端面21的孔24。该孔24沿光轴对称，孔24的内部填充有吸光物质。
其中，吸光物质可以是黑色硅胶材料，也可以是其他材料，只要不透光均可。
本申请实施例中，在配光元件的出光面上设置一个小孔，孔内填充有吸光物质，可以将第一光源经过该孔的光吸收，避免杂散光的产生。
在本申请的一个可能的实施方式中，该照明模组还包括光阑3。光阑3设置于配光元件2及反射元件4之间，配置为将经过配光元件2配置后的部 分光线过滤。其中，部分光线是指在预设范围之外的光线。
本申请实施例中，光阑将经过配置元件配置后的出射光线限定在预设范围内，即将预设范围之外的杂光过滤，使得经过光阑后的光为圆柱形的光束。
进一步地，通过光阑3过滤后的出射光线射到反射元件上形成的光斑为圆形。
也就是，在反射元件上形成与太阳光近似的圆形光斑，且圆形光斑的面积大于经过光阑后形成的圆柱形光束的横截面积。
在本申请的一个可能的实施方式中，为了对第一光源1发出的光进行优化，反射元件4的反射面采用抛物面型。
进一步地，该反射面上的母线满足贝塞尔曲线。
具体地，本发明提出用bezier曲面进行建模的方式，对扩展光源发出的光线进行综合优化。Bezier曲线又称贝兹曲线或贝济埃曲线，是应用于二维图形应用程序的数学曲线。它通过控制曲线上的四个点(起始点、终止点以及两个相互分离的中间点)来创造、编辑图形。其中起重要作用的是位于曲线中央的控制线。这条线是虚拟的，中间与贝塞尔曲线交叉，两端是控制端点。移动两端的端点时贝塞尔曲线改变曲线的曲率(弯曲的程度)；移动中间点(也就是移动虚拟的控制线)时，贝塞尔曲线在起始点和终止点锁定的情况下做均匀移动。Bezier曲线整体连续，控制点比较少，由它沿着中心轴旋转构建的自由曲面非常适用于光线优化。
基于此初始模型，在扩展光源上采用多个起始点，考虑到中心与边缘发光点，对反射系统的孔径同样进行取样，并进行光线追迹。针对5个发光面采样点及孔径面的五个采用点，共25条光线，综合进行准直优化。
贝塞尔函数关系如下式所示，使用4个控制点(P0，P1，P2，P3)来控制曲线形状，如图3所示即贝塞尔曲线。
B(t)＝P 0(1-t) 3+3P 1t(1-t) 2+3P 2t 2(1-t)+P 3t 3,t∈[0,1]
其中，B(t)为贝塞尔函数；P0为三次贝塞尔曲线的起始点坐标；P1和P2 分别为控制点坐标；P3为终止点坐标；t为曲线的速率。
在本申请的一个可能的实施方式中，如图1所示，该照明模组还包括：散热器7，该散热器7设置于第一光源1背离反射元件4的一侧。
本申请实施例中，在将散热器设置于第一光源下方，将第一光源散发的热量排出，大大延长光源的寿命，减少更换次数，增强用户体验。
在本申请的一个可能的实施方式中，该照明模组还包括收容光源组件、反射元件和光阑的盒体。
本申请还提供了一种灯具，如图4-7所示，该灯具包括：上述任一所述的照明模组、壳体8和面罩9。
其中，壳体8组设在面罩9上，照明模组安装于壳体8外部，照明模组在反射元件4上形成的光斑透过面罩9可见。也就是壳体罩在面罩的出光面的上方，通过该出光面可以看到反射元件4的反射面上的光斑。本申请实施例中，通过将照明模组设置在壳体外部，将壳体罩设在面罩上，可以通过面罩的出光面看到照明模组的反射元件上形成的光斑，营造出类似太阳光斑的场景。
在本申请的一个可能的实施方式中，该面罩9为导光元件5，导光元件5具有入光面及出光面。其中，入光面与出光面为非平行设置。
在本申请的一个可能的实施方式中，该灯具还包括：第二光源模组，该第二光源模组包括第二光源6，该第二光源6发射预设颜色的光。
其中，第二光源的发出的光可以是任何一种颜色的光，光的颜色可以是固定一种颜色，也可以是不固定的多种颜色，可以根据用户的需求来设定。
具体地，预设颜色为模拟蓝天的颜色。
第二光源模组设置于导光元件5的相对的两侧。其中，导光元件5的入光面配置为接收第二光源6的出射光线，该出射光线在导光元件5内部经过多次全反射后从导光元件的出光面射出。本申请实施例中，第二光源发出的光从导光元件的侧面射入到导光元件中，在导光元件中经过多次全反射，这 样就可以使得第二光源的光线呈现在整个导光元件上，用户可以在导光元件上看到第二光源呈现的场景，若是光为蓝色，就可以在导光元件，也就是面罩上看到类似蓝天的场景。
在一个具体实施方式中，第一光源的发出的白光经过配置元件的配置后从配置元件的出光面射出，射出的光线经过光阑的过滤后得到圆柱形的光束，该光束照射到反射元件上，在反射元件的反射面上形成圆形光斑，然后反射后透过导光元件(即面罩)，用户就可以透过面罩看到圆形光斑，进而营造出一种太阳在无限远处发射出的太阳光照进室内。同时，第二光源发出的模拟天空的蓝光从侧面照射到导光元件(即面罩)中，在导光元件中经过多次全反射后从导光元件的出光面呈现出类似蓝天的场景，用户可以在导光元件的出光面看到蓝天。
在本申请的实施例中，通过第一光源模拟太阳，通过第二光源模拟蓝天，将两个光源发出的光在导光元件上组合呈现出阳光透过蓝天照射进室内的场景，由于第一光源是在反射元件上形成的光斑，呈现给用户一种太阳在无限远处的感觉，可在有限空间内感受天空效果，满足人们生理心理需求。
本申请还提供了一种灯具，该灯具包括：上述任一所述的照明模组、第二光源模组、壳体8和面罩9。照明模组设置于壳体8外部，壳体8罩设于面罩9上，第二光源模组设置于面罩的相对的两侧。
照明模组的第一光源的出射光线经过配置元件的配置后在反射元件上形成光斑，并通过面罩9可见。
第二光源模组的出射光线经过面罩9的配置后在面罩9的出光面呈现。
本申请实施例中，通过面罩可以看到第一光源在反射元件形成的光斑，还可以看到第二光源在面罩上呈现的光。若是第一光源发出的光为白光，第二光源发出的光为蓝光，就可以呈现出阳光透过蓝天照射进室内的场景，由于第一光源是在反射元件上形成的光斑，呈现给用户一种太阳在无限远处的感觉，可在有限空间内感受天空效果，满足人们生理心理需求。
