以下结合附图，详细说明本申请各实施例提供的技术方案。
本申请实施例公开了一种灯具，如图1至图5所示，包括送风模块1以及照明模块2，通常情况下还可包括吸顶盘3以及驱动模组4。
送风模块1用于持续制造吹拂气流，起到无叶风扇的作用。具体地，如图2至图5所示，包括风机10以及环形壳体11，环形壳体11围成一环形区域12，并且环形壳体11具有内环面11a、外环面11b、连接内环面11a与外环面11b且相互背离的第一端面11c和第二端面11d，本实施例中第一端面 11c与第二端面11d分别朝向灯具相互背离的两侧，其中，第二端面11d所朝向的一侧在灯具的使用状态下通常为墙壁或天花板，而第一端面11c所朝向的一侧是指在灯具的使用状态下位于灯具背离墙壁或天花板的一片区域，也就是灯具的工作范围，灯具的照明以及出风方向均朝向这一范围。环形壳体11的内部设置有环形风道13，内环面11a上设置有连通环形风道13的进风口14，风机10位于环形区域12内，并且风机10的出风口100对准进风口14，环形壳体11上还设置有连通环形风道13的出风口15，出风口15朝第一端面11c所面对的一侧出风。
当风机10启动时，会不停将空气抽入并由风机10的出风口100以气流的形式送出，气流离开风机10的出风口100后会进入进风口14，并沿进风口14进入到环形风道13内。环形风道13会将气流沿环形输送至各个位置，再由出风口15朝第一端面11c所面对的一侧吹出。这些被吹出的气流可以朝第一端面11c的正前方吹出，也可以相对倾斜的角度吹出。
出风口15可以沿着环形壳体的周向延伸，形成窄口，以提高气流的流速。为了使气流在周向上的分布较为均匀，可以沿着环形壳体11的周向同时排布多个出风口15。
并且在此基础上，本实施例还可以通过改变这些出风口15的朝向的方式实现不同的出风效果。例如，可以将其中的部分或全部出风口15朝向环形壳体11的中心倾斜，这样这些出风口15吹出的气流可以向环形壳体11的中心偏移，加强灯具中心位置处的风力。或者，还可以将其中的部分或全部出风口15朝向环形壳体11的外围倾斜，这样这些出风口15吹出的气流可以具有更大的偏移量，从而提升灯具的吹拂范围。
当然，在一些实施例中，也可以同时具有朝向环形壳体11中心倾斜的出风口15以及朝向环形壳体11外围倾斜的出风口，甚至还可以同时具有朝向正前方设置的出风口15，这几种出风口15相互搭配能够形成更为复杂多变 的出风效果，提高用户感受。
在本实施例中，出风口15可以设置在环形壳体11的内环面11a、外环面11b或者第一端面11c上，但相较于设置在第一端面11c上的方案，出风口15设置在内环面11a或者外环面11b上其出风角度均会有一定的局限性，因此不做优选。而将出风口15设置在第一端面11c上则不会存在上述问题。并且，此时可以将环形风道13的形状设计为由临近第二端面11d的一侧至临近第一端面11c的一侧渐缩，这样气流在向第一端面11c上的出风口15流动的过程中会被逐渐加速，从而可以获得更高初速度的气流。
在本实施例中，进风口14可以朝环形区域12的内部凸出，形成一段气流通道。这样一方面可以使风机10的位置选择更加灵活，不必紧贴在环形壳体11。例如此时可以将风机10设置在环形区域12的中心位置，使送风模块1的重心更加趋于结构中心，有利于提升结构稳定性。另一方面，凸出的进风口14也可以对气流进行一定的梳理和导向，使气流拥有足够的空间由刚进入进风口14时的近乎于沿径向流动转变为在环形风道13内的周向流动，减小动能损失。进风口14与环形风道13可以平滑连接，以进一步减小风阻。
为了固定风机10，本实施例的送风模块1还可包括托盘16，托盘16位于环形区域12内且与环形壳体11固定连接，风机10固定在托盘16上。在本实施例中，托盘16可以单独与环形壳体11进行装配，也可以与环形壳体11一体设置。例如，如图2和图5所示，为了简化成型工艺，降低成本，环形壳体11可以包括上壳110和下壳112两部分，上壳110和下壳112共同围成环形风道13，其中第一端面11c位于下壳112上，第二端面11d位于上壳110上，此时，托盘16可以与下壳112一体设置。这样在进行装配时便可省去单独安装托盘16的工序。
为了对风机10进行更为周全的保护，本实施例中的送风模块1还可以包括上盖17，上盖17盖合在托盘16上并与托盘16共同形成容纳腔18，风机 10设置于容纳腔18内。为了使风机10能够正常进气，在上盖17和/或托盘16上需要设置进气口170。当托盘16与下壳112一体设置时，在下壳112上设置进气口170存在较大难度，成本较高，因此此时可以单独在上盖17上开设进气口170。
请继续参见图1至图5，本实施例中的照明模块2设置在环形壳体11临近第一端面11c的一侧，并且为了不妨碍出风，照明模块2需要位于环形区域12在该侧的投影范围内。在使用时，照明模块2会朝第一端面11c所面对的方向发出光线，即灯具的照明方向与出风方向是一致的。
吸顶盘3用于固定灯具。具体地，吸顶盘3固定于天花板或墙壁，送风模块1以第一端面11c背离吸顶盘3的方式固定在吸顶盘3上。照明模块2可以固定在送风模块1上，也可以直接穿过环形区域12与吸顶盘3固定连接。驱动模组4可以设置在吸顶盘3内并电性连接风机10以及照明模组2，驱动模组4可以控制风机10的转速进而调节风量。此外，驱动模组4还可以对照明模组2进行自动调光调色控制，例如可以设置传感器感受环境光照变化、声音或者温度，当监测到环境光照降低或者明显的声音时，驱动模组4可以控制照明模组2提升光照强度，为环境提供照明。当监测到环境温度升高到某一阈值时，驱动模组4可以控制风机10开启。除此之外，还可以设置接收模块接收遥控器、手机等控制信号，驱动模组4根据这些控制信号控制风机10以及照明模组2。
由于照明模块1设置在环形壳体11临近第一端面11c的一侧，与吸顶盘3的距离较远，因此优选固定在送风模块1上。照明模块1可以与环形壳体11相固定，当送风模块1具有托盘16时，照明模块1也可以与托盘16相固定。
具体地，托盘16与照明模块1可以通过螺栓5连接固定，螺栓5可以单独设置，也可以集成在托盘16或者照明模块1上。并且，螺栓5可以与螺母 配合，也可以与螺纹孔配合。为了使螺栓5更为稳定，本实施例还设置了垫板6，托盘16朝向风机10的一侧表面上设置有嵌槽160，垫板6嵌入嵌槽160内，螺栓5穿过并抵接垫板6。通过垫板6可以使螺栓5获得一个稳定的抵接面，从而提高螺栓5的连接稳定性，降低晃动。
本实施例中的照明模块2可以采用各种结构，例如发光组件20配合透镜、面罩形成吸顶灯结构，或者也可以根据需要增设反射器形成聚光灯结构，甚至也可以采用传统的灯泡。即本实施例中对照明模块2的结构没有限制。
考虑到减小灯具的整体厚度，照明模块2优选采用厚度较薄的结构，例如，照明模块2可以包括发光组件20、固定部21、导光件22以及透光板23，固定部21是照明模块2的主体结构，用于固定其它部件，同时也可用于照明模块2整体与其它结构的固定。固定部21可以采用强度较大的金属材料制成，发光组件20以及导光件22均固定在固定部21内，发光组件20的朝向与第一端面11c一致，用于向第一端面11c所面对的一侧发出光线。通常情况下照明模块会采用透镜以及透光罩为发光组件20配光，但透镜以及透光罩需要设置在发光组件20的前方，因此会大幅增加照明模组的厚度。本实施例中采用导光件22与透光板23作为配光元件。具体地，透光板23沿平行于第一端面11c的方向延伸且透光板23的一部分伸入固定部21内并与固定部21相固定。
透光板23具有入光面230以及出光面232，其中，出光面232与第一端面11c的朝向一致，入光面230则与出光面232相垂直。导光件22用于将发光组件20发出的光线导向至入光面230，导光件22可以采用弧状反射面等方式实现导光。这些光线进入透光板23后会沿着透光板23的延展方向传播并由出光面232射出。由于本实施例中的导光件22配合透光板23基本上平行排布，因此可以有效减小照明模组2的厚度。
在本实施例中，透光板23可以采用镜子等单侧半透明材料，这样用户无 法透过透光板23观察到透光板23的后方。而有些实施例中透光板23也可以采用完全透明的材质，例如玻璃等，这样可以使用户直接透过透光板23观察到后方的结构，使灯具具有不同的外观效果。然而，如果透光板采用完全透明的材质，则光线也有可能由透光板23背离出光面232的一侧表面射出，从而降低光照强度。对此，可以在透光板23背离出光面232的一侧表面设置若干用于反射光线的丝印点或激光码点。通过丝印点或激光码点可以将光线反射至出光面232，从而提高光照强度。丝印点或激光码点可以呈放射状、环状或者螺旋状等各种形状排布。
在本实施例中，透光板23的形状可以呈矩形、扇形等各种形状，而采用环形的透光板23能够获得最大的面积以及较为均匀的光照范围，因此本实施例中推荐透光板23采用环形结构，固定部21位于环形结构的中部，并且透光板23的内侧伸入到固定部21内。此时为了保护透光板23，还可以在透光板23的外侧围绕一圈保护套24进行保护。
本申请实施例采用的上述至少一个技术方案能够达到以下有益效果：
本申请实施例公开的灯具能够同时具有照明以及出风功能，相较于独立的灯具与无叶风扇的组合体积大幅降低，因此能够节省室内空间。
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。
