本申请涉及照明技术领域，尤其涉及一种照明灯具的光源系统及照明灯具。
背景技术
照明灯具广泛应用于家居照明、商业照明、工业照明、道路照明、景观照明、特种照明等多个领域，经过长时间的发展，人们对照明灯具的性能要求越来越高，这就给照明灯具的结构设计带来了更大的挑战。
采用传统光学方案的照明灯具存在从发光体直接照射出来的光线，这部分光线如果进入人眼中，会产生眩光问题，进而导致用户出现不舒服的体验感。因此，现有照明灯具存在用户体验较差的问题。
发明内容

为了解决上述问题，本申请采用下述技术方案：
一种照明灯具的光源系统，包括第一反射器和第二反射器，所述第一反射器套设于所述第二反射器内，所述第一反射器的第一端设有第一出光口，所述第一出光口位于所述第二反射器内，所述第二反射器的第三端设有第二出光口；
所述光源系统还包括第一发光体，所述第一发光体设置于所述第一反射器 内，所述第一反射器具有朝向所述第一发光体的第一反射面，在所述第一发光体的光轴方向上，所述第一反射面的正投影覆盖所述第一发光体的正投影；和/或，
所述光源系统包括第二发光体，所述第二发光体设置于所述第二反射器内，所述第二反射器具有朝向所述第二发光体的第二反射面，在所述第二发光体的光轴方向上，所述第二反射面的正投影覆盖所述第二发光体的正投影；
其中，所述第一发光体和所述第二发光体发出的光线经过所述第一反射器和所述第二反射器中的至少一者后自所述第二出光口射出。
一种照明灯具，包括上述光源系统。
本申请采用的技术方案能够达到以下有益效果：
本申请实施例公开的光源系统，通过对相关技术中的照明灯具的光源系统的结构进行改进，使得照明灯具的光源系统包括第一反射器和第二反射器，在光源系统包括第一发光体的情况下，第一发光体被第一反射面遮挡；在光源系统包括第二发光体的情况下，第二发光体被第二反射面遮挡。可见，本申请实施例公开的照明灯具的光源系统在能够正常投射出光线的情况下，实现第一发光体或第二发光体的隐藏，最终使得用户较难看到第一发光体或第二发光体，进而能够达到较好地防眩光的目的，以此改善用户使用照明灯具时的用户体验。

具体实施方式
为使本申请的目的、技术方案和优点更加清楚，下面将结合本申请具体实施例及相应的附图对本申请技术方案进行清楚、完整地描述。显然，所描述的实施例仅是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通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，都属于本申请保护的范围。
以下结合附图，详细说明本申请各个实施例公开的技术方案。
请参考图1和图2，本申请实施例公开一种照明灯具的光源系统，所公开的光源系统包括第一反射器200和第二反射器300。
第一反射器200和第二反射器300均是光源系统的反射器件，两者能够对光线进行反射。在本申请实施例中，第一反射器200套设于第二反射器300内。第一反射器200包括第一端230和第二端240，第一端230设有第一出光口231，第一出光口231位于第二反射器300内。第二反射器300包括第三端340和第四端350，第三端340开设有第二出光口341。
一种可选的实施方式中，本申请实施例公开的光源系统还可以包括第一发 光体110，第一发光体110设置于第一反射器200内，第一反射器200具有朝向第一发光体110的第一反射面210，在第一发光体110的光轴方向上，第一反射面210的正投影覆盖第一发光体110的正投影，进而能够使得第一反射面210能够覆盖第一发光体110，使得用户在正对第一出光口231时，无法观察到第一发光体110。在具体的工作过程中，第一发光体110发出的光线经过第一反射器200和第二反射器300中的至少一者后自第二出光口341射出，进而达到照明的目的。
在另一种可选的实施方式中，如图3所示，本申请实施例公开的光源系统还可以包括第二发光体120，第二发光体120设置于第二反射器300内，第二反射器300具有朝向第二发光体120的第二反射面310，在第二发光体120的光轴方向上，第二反射面310的正投影覆盖第二发光体120的正投影，进而能够使得第二反射面310能够覆盖第二发光体120，使得用户在正对第二出光口341时，无法观察到第二发光体120。在具体的工作过程中，第二发光体120发出的光线经过第一反射器200和第二反射器300中的至少一者后自第二出光口341射出，进而达到照明的目的。
本申请实施例公开的光源系统可以包括第一发光体110和第二发光体120中的至少一者，在光源系统同时包括第一发光体110和第二发光体120的情况下，照明灯具无疑具备更强的照明亮度，达到较好的照明效果。另外，可以通过设计第一反射器200和第二反射器300的结构，使得第一发光体110和第二发光体120发出的光线中不存在未经第一反射器200和第二反射器300反射而直接射出的部分。
第一发光体110和第二发光体120为光源系统的发光器件，第一发光体110和第二发光体120通常可以为LED发光体，LED发光体具有亮度较高、发热量较低、能耗较低以及寿命较长的优点。
本申请实施例公开的光源系统，通过对相关技术中的照明灯具的光源系统的结构进行改进，使得照明灯具的光源系统包括第一反射器200和第二反射器 300，在光源系统包括第一发光体110的情况下，第一发光体110设于第一反射器200内，并且在第一发光体110的光轴方向，第一反射面210的正投影覆盖第一发光体110的正投影，进而能够使得第一发光体110被第一反射面210遮挡。在光源系统包括第二发光体120的情况下，第二发光体120设于第二反射器300内，在第二发光体120的光轴方向上，第二反射面310的正投影覆盖第二发光体120的正投影，进而能够使得第二发光体120被第二反射面310遮挡。可见，本申请实施例公开的照明灯具的光源系统在能够正常投射出光线的情况下，实现第一发光体110或第二发光体120的隐藏，最终使得用户较难看到第一发光体110或第二发光体120，进而能够达到较好地防眩光的目的。
在本申请实施例中，第一反射器200的结构可以有多种。一种可选的方案中，在第一方向上，第一反射器200的横截面面积递减，需要说明的是，第一方向指的是自第一出光口231向第二出光口341延伸的方向，第一反射器200的横截面为垂直于第一方向的截面。此种情况下，第一反射器200的轮廓尺寸逐渐减小，从而能够在确保反射作用的基础上，较好地遮挡第一发光体110，达到隐藏第一发光体110的目的。当然，第一反射器200还可以为其它结构，只要能够确保投射到其上的光线能够被反射至第二出光口341后从第二出光口341投射出或者能够被反射至第二反射器300后由第二反射器300反射至第二出光口341即可，本申请实施例不限制第一反射器200的具体形状。
同理，第二反射器300的结构可以有多种，请再次参考图1，一种可选的方案中，第二反射器300可以包括第一反射部320以及与第一反射部320相连的第二反射部330，第一反射部320和第二反射部330沿第一方向依次排布，在第一方向上，第一反射部320的横截面面积递减，第二反射部330的横截面面积递增。第二出光口341开设在第二反射部330背离第一反射部320的端部。此种结构能够在第一反射部320和第二反射部330的衔接处较容易形成遮挡结构，从而实现对第一发光体110的遮挡。
在另一种具体的实施方式中，如图4至图6所示，第二反射器300包括第 一反射部320以及与第一反射部320相连的第二反射部330，第一反射部320至少部分套设于第二反射部330内，在第一方向上，第一反射部320的横截面面积递减，第二反射部330的横截面面积递增。由于第一反射部320的横截面面积递减，因此较容易形成遮挡结构，更容易实现对第二发光体120的遮挡。与此同时，第一反射部320的至少部分套设于第二反射部330之内，因此能够使得第二反射器300在第一方向上的长度更小，有利于构件的小型化。
在进一步的技术方案中，第一发光体110可以设于第一反射器200的第二端240内，此种结构更方便第一发光体110的布设，与此同时，第一反射器200的第二端240距第一出光口231的距离更大，进而更有利于实现第一发光体110的隐藏。在更进一步的技术方案中，第一发光体110可以被配置为邻近第一反射器200的边缘。在此种情况下，第一反射部320的与第二反射部330相连的一端相对于第一发光体110更靠近第一发光体110的光轴，此时第一反射部320的更多部分可以遮挡第一发光体110，能够更有利于第一反射面210对第一发光体110的遮挡。
在本申请实施例公开的光源系统中，第二发光体120可以设置于第一反射部320背离第二反射部330的一端内，即第二发光体120设置于第一反射部320背离第二出光口341的一端内。此种结构使得第二发光体120更靠近第二反射器300的第四端350，进而更方便对第二发光体120的布设。与此同时，第二反射器300的第四端距第二出光口341更远，更容易实现对第二发光体120的遮挡。更进一步地，第二发光体120可以被配置为邻近第一反射部320的边缘，使得第一反射部320的与第二反射部330相连的一端相对于第二发光体120更靠近第二发光体120的光轴，此时第一反射部320的更多部分可以遮挡第二发光体120，进而更有利于第二反射面310对第二发光体120的遮挡。
具体的，第一反射部320与第二反射部330可以为一体式结构，也可以通过装配固定相连，本申请实施例不限制第一反射部320与第二反射部330的具体固定方式。
如上文所述，第一反射器200套设于第二反射器300内。一种可选的方案中，第一反射器200可以设置于第一反射部320内，此种结构能够确保第一反射器200套设于第二反射器300，同时还能够避免第一反射器200伸至第二反射部330内，也就能够避免对第二反射部330反射光线造成不良影响。
在进一步的技术方案中，第一反射器200的第二端240与第一反射部320背离第二出光口341的一端平齐。此种结构能够较容易使得第一反射器200和第二反射器300安装在同一安装基础(例如后文所述的电路板500)上，从而简化光源系统的装配操作。
一种可选的方案中，第一反射部320邻近第二出光口341的一端的横截面面积为第一面积，第一反射部320的另一端的横截面面积为第二面积，第一面积与第二面积之间的比值可以为0.6～0.9。此种结构能够使得第一反射部320的渐缩程度不至于过大而影响光源系统的出光量，同时又能够对第一发光体110实施较好的遮挡。
为了保证第一发光体110和第二发光体120发出的光线能够被可靠地反射，在平行于前文所述第一方向的截面内，第一出光口231与第二出光口341之间的连线与第一方向之间的夹角α小于或等于45°。如此设置可以使得第二出光口341相对于第一出光口231尽量收敛，即使第一发光体110和第二发光体120发出的光线未被第一反射器200反射，也会被第二反射器300反射，从而改善光源系统的光效。
在本申请实施例中，第一反射器200的外周面可以设置有第三反射面220，第三反射面220可以为弧面，第三反射面220向第一反射器200的第二端240所在的一侧弯曲。第三反射面220可以进一步反射第二发光体120发出的光线，使得第二发光体120所发出的光线可以更多地自光源系统射出，从而提升光源系统的出光量。与此同时，第三反射面220为弧面时，第三反射面220的面积有所增加，更多的光线可以到达第三反射面220，进而被第三反射面220反射。并且，该第三反射面220可以将更多的光线反射至第二反射器300，从而使得 整个光源系统的匀光效果更好。
在本申请实施例中，第一发光体110和第二发光体120的数量可以为一个，也可以为至少两个。一种可选的方案中，第一发光体110的数量可以为至少两个，各第一发光体110沿第一反射器200的周向排布，最终能够形成环状发光结构，实现多方向的均匀发光效果。
同理，一种可选的方案中，第二发光体120的数量可以为至少两个，各第二发光体120可以沿第二反射器300的周向排布，最终也能够形成环状发光结构，实现多方向的均匀发光效果。
在进一步的技术方案中，本申请实施例公开的光源系统还可以包括至少一个配光件400，配光件400罩设在第一发光体110或第二发光体120的外部，配光件400可以对第一发光体110或第二发光体120发出的光线进行配光，配光件400可以为匀光器件，也可以为聚光器件，本申请实施例不限制配光件400的具体种类。
一种可选的方案中，上述配光件400的数量可以为一个，也可以为至少两个，配光件400可以仅罩设一部分第一发光体110或第二发光体120，但是为了避免相互之间的干扰，配光件400的数量与第一发光体110和第二发光体120的总数相等，每个第一发光体110的外部和每个第二发光体120的外部均罩设一个所述配光件400。也就是说，每个第一发光体110和每个第二发光体120均单独配置有一个配光件400为其单独配光，该配光件400罩设在第一发光体110或第二发光体120的外部，从而能够缓解第一发光体110或第二发光体120相互之间的光学干扰，同时还可以改善各个第一发光体110或第二发光体120的配光效果，使得整个光源系统的光效更优。
一种优选的方案中，所述的多个配光件400可以为一体式结构。在组装的过程中，多个配光件400整体进行装配，无需单个安装，进而能够方便组装及提高装配效率。
在其他实施例中，配光件400为环形件，同一个配光件400覆盖沿同一圆 周方向排布的多个第一发光体110，或者同一个配光件400覆盖沿同一圆周方向排布的多个第二发光体120，此实施例可以降低配光件400的数量，从而便于快速组装光源系统。
可选地，配光件400可以是透镜，具体可以是凸透镜，也可以是凹透镜，也可以是透镜组，透镜具有较好的配光效果，且结构比较简单。在进一步的技术方案中，配光件400可以为平凸透镜，也可以为具有容纳空间的罩状透镜，具体的，第一发光体110或第二发光体120可以位于该容纳空间之内，在此种情况下，配光件400不但能够发挥配光作用，还能够发挥保护第一发光体110或第二发光体120的作用。
在本申请实施例中，第二反射器300的第四端350为敞口端，具体的，本申请实施例公开的光源系统中，第二反射器300的第四端350的端口可以封堵有电路板500，第一发光体110和第二发光体120可以固定在电路板500上，电路板500为第一发光体110和第二发光体120提供安装位置。具体的，第一发光体110和第二发光体120可以与电路板500电连接，进而由电路板500供电。
在进一步的技术方案中，电路板500可以与第二反射器300固定相连，在整个照明灯具的组装过程中，第二反射器300可以以电路板500为安装基础进行组装。与此同时，电路板500还能够封堵第二反射器300的第四端350的端口，进而避免第一发光体110和第二发光体120发出的光线从第二反射器300的第四端350的端口漏出。
在进一步的技术方案中，电路板500背离第一发光体110或第二发光体120的一侧设置有散热座，散热座能够起到散热的作用。散热座可以由能够高效散热的材料制成，例如散热座可以是不锈钢散热座，或铝材散热座。或者，散热座可以设计成较容易散热的机构，例如，散热座包括呈阵列分布的多个散热针或散热片。
散热座可以直接与电路板500通过导热胶层粘接固定，在此种情况下，电 路板500及其上设置的第一发光体110或第二发光体120在工作时产生的热量能够较快地通过导热胶层传输至散热座上，最终通过散热座传输至整个照明灯具，达到快速散热的目的。
基于本申请实施例公开的光源系统，本申请实施例还公开一种照明灯具，所公开的照明灯具包括上文实施例所述的光源系统。
本申请实施例公开的照明灯具可以为筒灯、射灯等，本申请实施例不限制照明灯具的具体种类。
一种可选的方案中，本申请实施例公开的照明灯具还可以包括电路板500和壳体600，第一发光体110和第二发光体120设置于电路板500，电路板500设置于壳体600的底壁630，从而提升电路板500的安装强度。第一反射器200位于壳体600的侧壁640与第一发光体110之间；或者，第一反射器200位于第二反射器300与第一发光体110之间。相对而言，当第一反射器200位于第二反射器300与第一发光体110之间时，第二反射器300更便于安装，即可以将第二反射器300与电路板500固定连接。第二发光体120位于壳体600的侧壁640与第一反射器200之间；或者，第二发光体120位于第二反射器300与第一反射器200之间。相对而言，当第二发光体120位于第二反射器300与第一反射器200之间时，第二反射器300可以包围第二发光体120，从而更好地反射光线。
进一步地，照明灯具还可以包括面罩700，壳体600具有内腔610和开口620，面罩700安装在开口620处，且面罩700与壳体600围成光学腔，光源系统设置在光源腔中，即第一反射器200和第二反射器300均设置于光学腔内，且第一出光口231的朝向与开口620的朝向一致。第一发光体110和第二发光体120发出的光线经第一反射器200和第二反射器300反射后自面罩700射出，该面罩700可以进一步改善照明灯具的匀光效果。
可选地，第二反射器300可以固定于面罩700与壳体600的底壁630之间；或者，第二反射器300固定于面罩700与电路板500之间。这两种设置方式都 可以更好地保证光线经过反射后再穿过面罩700而射出，进而改善照明灯具的光效。
为了更好地实现光源系统的驱动，照明灯具除了包括电路板500以外，还可以包括驱动器800，该驱动器800设置于电路板500。可选地，驱动器800可以设置于电路板500朝向第一出光口231的一侧，也可以设置于电路板500背离第一出光口231的一侧，本申请实施例对此不作限制。
本申请上文实施例中重点描述的是各个实施例之间的不同，各个实施例之间不同的优化特征只要不矛盾，均可以组合形成更优的实施例，考虑到行文简洁，在此则不再赘述。
以上所述仅为本申请的实施例而已，并不用于限制本申请。对于本领域技术人员来说，本申请可以有各种更改和变化。凡在本申请的精神和原理之内所作的任何修改、等同替换、改进等，均应包含在本申请的权利要求范围之内。
