Description

照明灯具及其光源系统 技术领域
本申请涉及照明灯具技术领域，尤其涉及一种照明灯具及其光源系统。
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
本申请公开一种照明灯具的光源系统，能够解决目前的照明灯具存在眩光较为严重的问题。
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，包括第一发光体、第二发光体、第一反射器、第二反射器和第三反射器，其中：
所述第二反射器和第三反射器均至少部分设置于所述第一反射器内，所述第三反射器位于所述第二反射器围绕的空间内，所述第一反射器包括第一端，所述第一端设有出光口；
所述第一发光体和所述第二发光体均至少部分设置于所述第一反射器内，所述第一发光体设置在所述第二反射器与所述第一反射器之间，所述第二发光体设置在所述第二反射器与所述第三反射器之间；
所述第二反射器的朝向所述出光口的端部在所述出光口的朝向上的投影为第一投影，所述第三反射器的朝向所述出光口的端部在所述出光口的朝向上的投影为第二投影，所述第一发光体在所述出光口的朝向上的投影为第三投影，所述第二发光体在所述出光口方向的投影为第四投影，所述第一投影覆盖所述第三投影，所述第二投影覆盖所述第四投影。
本申请采用的技术方案能够达到以下有益效果：
本申请实施例公开照明灯具的光源系统，通过对相关技术中的照明灯具进行改进，使得照明灯具的光源系统包括第一反射器、第二反射器和第三反射器，同时使得第一发光体在出光口的朝向上的第三投影，能够被第二反射器的朝向出光口的端部在出光口朝向的第一投影覆盖，最终能够使得第一发光体能够被第二反射器遮挡，以及使得第二发光体在出光口的朝向上的第四投影，能够被第三反射器的朝向出光口的端部在出光口朝向的第二投影覆盖，最终能够使得第二发光体能够被第三反射器遮挡。第一发光体和第二发光体发出的光线可被第一反射器、第二反射器和第三反射器中的至少一者反射后从出光口投射出。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，实现第一发光体和第二发光体的隐藏，最终使得用户透过出光口无法看到第一发光体和第二发光体，进而能够达到较好的防眩光的目的。

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至图4，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发光体100、第二发光体200、第一反射器300、第二反射器400和第三反射器500。
第一发光体100和第二发光体200均为光源系统的发光器件，第一发光体100和第二发光体200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。在本申请实施例中，第一发光体100和第二发光体200均至少部分设置于第一反射器300内。在较为优选的方案中，第一发光体100和第二发光体200均完全位于第一反射器300内，从而确保第一发光体100和第二发光体200发出的光线更多地被反射后最终被投射出。
第一反射器300、第二反射器400和第三反射器500均为光源系统的反射器件，均能够用于对第一发光体100和第二发光体200中的至少一者发出的光线进行反射，达到配光的目的。在本申请实施例中，第一反射器300为 光源系统的外围结构件，第二反射器400的至少部分和第三反射器500的至少部分均设置于第一反射器300内，而且，第三反射器500位于第二反射器400围绕的空间内。
如上文所述，第一反射器300为光源系统的外围结构件，第一反射器300包括第一端310和第二端320，第一端310设有出光口311，第一发光体100和第二发光体200发出的光线均能够最终通过出光口311投射至光源系统之外，进而实现照明。
在本申请实施例中，第二反射器400的朝向出光口311的端部在出光口311的朝向上的投影(正投影)为第一投影，第三反射器500的朝向出光口311的端部在出光口311的朝向上的投影(正投影)为第二投影，第一发光体100设置在第二反射器400与第一反射器300之间，第一发光体100在出光口311的朝向上的投影(正投影)为第三投影，第二发光体200设置在第二反射器400与第三反射器500之间，第二发光体200在出光口311方向的投影(正投影)为第四投影，第一投影覆盖第三投影，第二投影覆盖第四投影。
第一投影覆盖第三投影，使得第二反射器400能够覆盖第一发光体100，进而在正对着出光口311向第一反射器300内观察时，无法看到被覆盖的第一发光体100；同理，第二投影覆盖第四投影，使得第三反射器500能够覆盖第二发光体200，进而在正对着出光口311向第一反射器300内观察时，无法看到被覆盖的第二发光体200。也就是说，第一发光体100和第二发光体200发出的光线无法直接从出光口311投射出。
请参考图1，在具体的工作过程中，第二发光体200发出的光线可经过第二反射器400、第三反射器500和第一反射器300中的至少一者的反射， 最终通过出光口311投射至光源系统之外。请参考图2，在具体的工作过程中，第一发光体100发出的光线可经过第二反射器400和第一反射器300中的至少一者的反射，最终通过出光口311投射至光源系统之外。
本申请实施例公开的照明灯具的光源系统，通过对相关技术中的照明灯具进行改进，使得照明灯具的光源系统包括第一反射器300、第二反射器400和第三反射器500，同时使得第一发光体100在出光口311的朝向上的第三投影，能够被第二反射器400的朝向出光口311的端部在出光口311朝向的第一投影覆盖，最终能够使得第一发光体100能够被第二反射器400遮挡，以及使得第二发光体200在出光口311的朝向上的第四投影，能够被第三反射器500的朝向出光口311的端部在出光口311朝向的第二投影覆盖，最终能够使得第二发光体200能够被第三反射器500遮挡。第一发光体100和第二发光体200发出的光线可被第一反射器300、第二反射器400和第三反射器500中的至少一者反射后从出光口311投射出。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100和第二发光体200的隐藏，最终使得用户透过出光口311无法看到第一发光体100和第二发光体200，进而能够达到较好的防眩光的目的。
如上文所述，第二反射器400的至少部分设置于第一反射器300内，也就是说，第二反射器400可以部分设置于第一反射器300内，也可以全部设置于第一反射器300内。在较为优选的方案中，第二反射器400可以全部设置于第一反射器300内，进而能够充分利用第一反射器300的内部空间进行设置，有利于使得光源系统的结构更加紧凑，占用空间较小。
同理，第三反射器500的至少部分设置于第一反射器300内，也就是说，第三反射器500可以部分设置于第一反射器300内，也可以全部设于第一反 射器300内。在较为优选的方案中，第三反射器500可以全部设置于第一反射器300内，进而能够充分利用第一反射器300的内部空间进行设置，有利于使得光源系统的结构更加紧凑，占用空间较小。
在本申请实施例中，第一反射器300可以在出光口311的朝向上，横截面面积递增，从而能够形成较大面积的出光口311，进而有利于更多的光线投射出，达到提高光利用率的目的。
一种可选的方案中，在出光口311的朝向上，第二反射器400的横截面的面积递增，第二反射器400的横截面为第二反射器400在垂直于出光口311的朝向方向的截面。此种结构使得第二反射器400朝向出光口311的端部更容易形成遮挡第一发光体100的结构，同时还能够使得第二反射器400形成较为平滑的反射结构，有利于光源系统形成更均匀的光线投射。
同理，在另一种可选的方案中，在出光口311的朝向上，第三反射器500的横截面的面积递增，第三反射器500的横截面为第三反射器500在垂直于出光口311的朝向方向的截面。此种结构使得第三反射器500朝向出光口311的端部更容易形成遮挡第二发光体200的结构，同时还能够使得第三反射器500形成较为平滑的反射结构，有利于光源系统形成更均匀的光线投射。
本申请实施例公开的光源系统中，第二反射器400和第三反射器500中的至少一者可以为回转体，方便制造，而且有利于形成差异较小的反射区域，有利于确保光源系统的出光性能。与此同时，回转体结构具有方便制造的优势。
第一发光体100和第二发光体200可以为一个，也可以为多个。一种可选的方案中，在第二反射器400和第三反射器500均为回转体的情况下，第一发光体100和第二发光体200均可以为多个。多个第一发光体100可以围 绕第二反射器400设置，多个第二发光体200可以围绕第三反射器500设置。此种结构能够使得多个第一发光体100和多个第二发光体200均能够形成环状发光结构，环状发光结构发出的光线经过反射后，最终能够从出光口311投射出的光线更加均衡。
为了进一步提高光效，一种可选的方案中，第一发光体100可以为多个，本申请实施例公开的光源系统还可以包括多个第一配光器件700，每个第一配光器件700均罩设在一个第一发光体100上。每个第一配光器件700均能够对第一发光体100发光的光线进行配光。第一配光器件700可以为反射器，也可以为配光透镜。本申请实施例不限制第一配光器件700的具体种类。多个第一配光器件700可以为相互独立的单体结构件，当然，多个第一配光器件700可以为一体式结构件，此种情况下，多个第一配光器件700形成一个不可拆分的整体，方便光源系统进行更高效地装配。
同理，在另一种可选的方案中，第二发光体200可以为多个，光源系统还可以包括多个第二配光器件800，每个第二配光器件800均罩设在一个第二发光体200上，每个第二配光器件800均能够对第二发光体200发出的光线进行配光。第二配光器件800可以为反射器，也可以为配光透镜，本申请实施例不限制第二配光器件800的具体种类。多个第二配光器件800可以为相互独立的单体结构件，当然，多个第二配光器件800可以为一体式结构件，此种情况下，多个第二配光器件800形成一个不可拆分的整体，方便光源系统进行更高效地装配。
如上文所述，第一配光器件700和第二配光器件800的种类及结构可以有多种，例如，第一配光器件700可以为平凸透镜。一种可选的方案中，第一配光器件700可以具有第一容纳空间710，具体的，第一配光器件700可 以为罩状结构件。第一发光体100位于第一容纳空间710之内，在此种情况下，第一配光器件700还能够为第一发光体100实施防护。
同理，第二配光器件800可以为平凸透镜，一种可选的方案中，第二配光器件800可以具有第二容纳空间810，具体的，第二配光器件800可以为罩状结构件。第二发光体200位于第二容纳空间810之内，在此种情况下，第二配光器件800还能够为第二发光体200实施防护。
本申请实施例公开的光源系统还包括电路板600，电路板600封堵在第一反射器300的第二端320的端口。电路板600与第一反射器300固定相连。第一发光体100和第二发光体200均可以固定在电路板600上。第二反射器400和第三反射器500均可以固定在电路板600上。电路板600能够为第一发光体100和第二发光体200提供安装基础及供电，同时还能够为第二反射器400和第三反射器500提供安装基础。而且，电路板600封堵在第一反射器300的第二端320的端口，能够避免第一发光体100和第二发光体200发射的光线从第一反射器300的第二端320的端口射出。
一种可选的实施方式中，电路板600、第一发光体100和第二发光体200形成光源板，从而实现整体式的安装。
为了提高光线的利用率，在一种可选的方案中，电路板600可以包括中心区域610和围绕中心区域610设置的环状外围区域620，第二反射器400朝向出光口311的端部，以及第三反射器500朝向出光口311朝向出光口311的端部在电路板600上的正投影均位于中心区域610之内，第一发光体100和第二发光体200均可以设置在中心区域610之内，也就是说，第一发光体100和第二发光体200设置在环状外围区域620之外。此种电路板600分区设计的方式，使得电路板600上安装第一发光体100和第二发光体200的位 置更加明确，进而有利于第一发光体100和第二发光体200的组装。
在进一步的技术方案中，电路板600背离第一发光体100或第二发光体200的一侧可以设置有散热座1000，散热座1000能够起到散热的作用。散热座1000可以由能够高效散热的材料制成，例如散热座1000可以是不锈钢散热座。或者，散热座1000可以设计成较容易散热的机构，例如，散热座1000包括呈阵列分布的多个散热针。
散热座1000可以直接与电路板600通过导热胶层粘接固定，在此种情况下，电路板600及其上设置的第一发光体100和第二发光体200在工作时产生的热能够较快地通过导热胶层传输至散热座1000上，最终通过散热座1000传输至整个照明灯具，达到快速散热的目的。
在具体的工作过程中，第一发光体100和第二发光体200发出的光线有可能在第一反射器300或第二反射器400的反射作用下，投射至中心区域610或环状外围区域620，为了提高光的利用率，一种可选的方案中，环状外围区域620和中心区域610中的至少一者朝向出光口311的表面设置有反射层900，反射层900能够使得投射到环状外围区域620或中心区域610的光线被反射，进而能够提高光线的利用率。
与此同时，环状外围区域620设置有反射层900，反射层900能够使得环状外围区域620呈现亮面，进而能够提高光源系统的照明性能。
一种可选的方案中，在第二反射器400设置于第一反射器300内的情况下，在本申请实施例公开的光源系统中，第二反射器400与第一反射器300的第二端320的端面之间的距离可以为零。第二反射器400与第一反射器300的第一端310的端面之间的距离可以大于零。在此种情况下，第二反射器400和第一发光体100能够距离出光口311更远，进而更有利于达到更好地防眩光的目的。
同理，在第三反射器500设置于第一反射器300的情况下，在本申请实 施例公开的光源系统中，第三反射器500与第一反射器300的第二端320的端面之间的距离为零。第三反射器500与第一反射器300的第一端310的端面之间的距离大于零。在此种情况下，第三反射器500和第二发光体200能够距离出光口311更远，进而更有利于达到更好地防眩光的目的。
一种可选的方案中，第三反射器500的高度可以大于第二反射器400的高度，从而能够使得第三反射器500具备较多的区域去反射第二发光体200发出的光线。而且，也有利于对其它方向反射过来的光线进行再次反射，达到更多级反射的目的。需要说明的是，第三反射器500的高度，指的是第三反射器500朝向出光口311的端面距第一反射器300的第二端320的端面之间的距离；第二反射器400的高度，指的是第二反射器400朝向出光口311的端面距第一反射器300的第二端320的端面之间的距离。
