请参阅图1和图2所示，定义扇叶结构100靠近侧缘13的一端为扇叶端部1a，扇叶结构100远离侧缘13的一端为扇叶根部1b，扇叶结构100包括前缘11、后缘12、侧缘13以及弧面14，侧缘13连接于前缘11和后缘12之间，并设于扇叶端部1a，且前缘11、后缘12和侧缘13之间无痕相接，并围设形成弧面14的外周边缘。换言之，前缘11和后缘12分别位于扇叶结构100的宽度方向的两侧，弧面14连接于前缘11和后缘12之间。
优选地，前缘11呈内凹弧形状设置，后缘12和侧缘13均呈外凸弧形状设置，换言之，前缘11和后缘12各自整体上朝向背风侧凸出，使得扇叶结构100在其长度方向上的两端部位于前侧，中部区域则相对位于后侧，如此设置，当扇叶结构100高速旋转时，扇叶结构100能够承受来自气流的猛烈冲击，而且不易发生变形或弯折，从而提高扇叶结构100的整体强度和稳定性，进而提升扇叶结构100的使用寿命。
从整体上看，前缘11和后缘12在水平方向上的高度均自扇叶根部1b朝向扇叶端部1a逐渐增大，且后缘12在水平方向上的高度低于前缘11在水平方向上的高度，使得弧面14自前缘11至后缘12向下平滑弯曲延伸，从而使扇叶结构100呈现受风侧高而背风侧低的结构形态。如此，在扇叶结构100高速旋转时，气流由前缘11进入扇叶结构100，在受到弧面14的导流作用后，经由后缘12流出扇叶结构100，从而改变了气流方向，提升了兜风效果，进而提升了扇叶结构100的吹风效果。
进一步地，前缘11自扇叶根部1b朝向扇叶端部1a逐渐向上平滑倾斜延伸，即前缘11沿其长度方向的两端不在同一水平面上。后缘12的结构设计与前缘11的结构设计相同。如此使得整个扇叶根部1b的高度低于扇叶端部1a的高度，一方面，可以有效改善气体流动的方向，从而达到较佳的吹风效果。另一方面，在扇叶结构100的收合过程中，相邻扇叶结构100之间呈交错排列，且俯视时互不交叠，即相邻扇叶结构100在水平面上的正投影互不重叠。前一个扇叶结构100的后缘12的靠近扇叶端部1a的一侧与后一个扇叶结构100的前缘11的靠近扇叶根部1b的一侧相对设置，即，前一扇叶结构100的扇叶端部1a位于与其相邻的后一扇叶结构100的扇叶根部1b的前边内侧，且两者之间留有间隙，使得扇叶结构100 可以自由伸缩旋转，而且还有利于风扇灯200产品的小型化。
扇叶结构100的最高点位于前缘11靠近扇叶端部1a的一端，扇叶结构100的最低点位于后缘12靠近扇叶根部1b的一端。其中，扇叶结构100的最高点与扇叶根部1b之间的距离占扇叶结构100总长度的60％～80％，优选为四分之三。扇叶结构100的最高点相对于扇叶根部1b所在的水平面的高度范围为40mm～100mm，优选为80mm。另外，扇叶结构100的最低点所在的水平面与扇叶根部1b所在的水平面齐平。如此可以提升扇叶结构100的兜风效果，从而提高出风量。
除此以外，在扇叶结构100的实际运行过程中，扇叶根部1b的线速度较大，扇叶端部1a的线速度较小。在一些实施例中，将扇叶结构100从扇叶根部1b至扇叶端部1a逐渐加宽，一方面，可以提升整个扇叶结构100的强度和稳定性，使扇叶结构100能够承受较大的离心作用而不发生变形或损坏，保证了扇叶结构100的正常使用。另一方面，在一定程度上可以使更多的空气随着扇叶结构100产生更大的流动速度，从而可以提升扇叶结构100的风力。在其他实施例中，还可以在扇叶根部1b至扇叶端部1a的方向，将扇叶结构100的宽度设置为定值，即前缘11到后缘12的距离保持不变。
前缘11的曲率半径自扇叶根部1b至扇叶端部1a逐渐增大，后缘12的曲率半径呈现先逐渐增大后逐渐减小的规律性变化趋势，使得后缘12保持弯曲形状。侧缘13具有对气流的导流功能，可以降低扇叶结构100对于气流的阻力，从而降低能耗以及噪声。侧缘13具有与前缘11相连的第一端以及与后缘12相连的第二端，其中，侧缘13的曲率半径自第一端至第二端先减小后增大。总之，前缘11和侧缘13的曲率半径变化趋势，使得扇叶结构100能够降低其在运行过程中所受到的气流冲击作用，进而提升其整体强度。
请参阅图3所示，具体地，前缘11包括靠近扇叶根部1b的第一弧段111以及与侧缘13相连的第二弧段112，第一弧段111的曲率半径小于第二弧段112的曲率半径。前缘11的曲率半径位于100mm～110mm之间。优选地，第一弧段111和第二弧段112的曲率半径分别为107.7mm和109.0mm。后缘12的曲率半径使得后缘12保持弯曲形状，后缘12包括自扇叶根部1b朝向扇叶端部1a延伸的第三弧段121、第四弧段122、第五弧段123、第六弧段124、第七弧段125和第八弧段126，后缘12的曲率半径自第三弧段121至第七弧段125呈现先增大后减小的循环趋势。后缘12的曲率半径位于85mm～190mm之间。在一些实施例中，后缘12的曲率半径范围为90.7mm～185.2mm，优选地，第三弧段121、第四弧段122、第五弧段123、第六弧段124、第七弧段125和第八弧段126的曲率半径具体分别为94.5mm、185.2mm、90.7mm、174.2mm、113.8mm和181.1mm。
侧缘13具有对气流的导流功能，可以降低扇叶结构100对于气流的阻力，从而降低能耗以及噪声。侧缘13具有与前缘11相连的第一端以及与后缘12相连的第二端，其中，侧缘13的曲率半径自第一端至第二端呈现先减小后增大的变化趋势，使得侧缘13整体上为较为圆滑的弧形结构，可以提升扇叶结构100的整体强度和稳定性。具体地，侧缘13包括相 互连接的第九弧段131、第十弧段132、第十一弧段133和第十二弧段134，侧缘13的第一端设于第九弧段131，侧缘13的第二端设于第十二弧段134，且侧缘13的曲率半径自第九弧段131至第十弧段132逐渐减小，并自第十弧段132至第十二弧段134逐渐增大。侧缘13的曲率半径位于30mm～100mm之间，优选地，侧缘13的曲率半径范围位于30.6mm～97.6mm之间，其中，第九弧段131的曲率半径小于第十二弧段134的曲率半径，第九弧段131和第十二弧段134的曲率半径分别为72.2mm和97.6mm。
优选地，前缘11的平均曲率半径小于后缘12的平均曲率半径，且大于侧缘13的平均曲率半径，可以提升扇叶结构100的整体强度和稳定性。通过对前缘11、后缘12及侧缘13的曲率半径进行设置，使得扇叶结构100的兜风效果得到了提升，继而提高了出风量。
如图4所示，具体地，在弧面14的宽度方向上，弧面14包括自扇叶根部1b朝向扇叶端部1a设置的第一横截面、第二横截面和第三横截面(分别对应第一虚线A、第二虚线B和第三虚线C处的截断面)，即第一横截面、第二横截面和第三横截面均为弧面14沿其宽度方向的横截面。从整体上看，弧面14的横截面的横向曲率半径自前缘11朝向后缘12先逐渐增大后逐渐减小，换言之，弧面14的横向曲率自前缘11朝向后缘12先逐渐减小后逐渐增大，如此可以获得很好的兜风效果。弧面14的纵向曲率半径自扇叶根部1b朝向扇叶端部1a先逐渐减小后基本不变，换言之，弧面14的纵向曲率自扇叶根部1b朝向扇叶端部1a先逐渐增大后保持基本不变。如此，一方面，使得扇叶结构100应用在风扇灯200产品中，可以减小风阻，从而获得更好的吹风效果；另一方面，还可以提升扇叶结构100的整体强度。
扇叶结构100的厚度自扇叶根部1b向扇叶端部1a逐渐减小，即扇叶根部1b较厚，扇叶端部1a较薄，整体厚度呈渐变式过渡，如此可以增强扇叶结构100的整体强度和稳定性，进而保证扇叶结构100在高速旋转时不会发生变形、弯折，保证了扇叶结构100的正常使用。前缘11和后缘12的厚度均自扇叶根部1b朝向扇叶端部1a逐渐减小以形成渐变弯曲结构，且在弧面14的宽度方向上，前缘11的厚度小于弧面14的厚度，使得吹出的风面积更广、更加柔和，让人感受更加舒适，从而实现很好的切风效果。
请参阅图5至图18所示，本申请还揭示了一种风扇灯200，包括风扇灯主体201及多个扇叶组件，扇叶组件包括前述扇叶结构100和连接结构2，扇叶结构100与连接结构2固定连接，通过连接结构2可收合或展开地设置于风扇灯主体201的周部上，可以提高风扇灯200的整体强度和吹风效果。
连接结构2固定连接于扇叶根部1b远离扇叶端部1a的一侧，扇叶结构100通过该连接结构2与风扇灯主体201连接。具体地，该连接结构2设于前缘11和后缘12之间，并突出设置在扇叶根部1b，便于其与风扇灯主体201连接。在一些实施例中，连接结构2与弧面14组装配合形成一个整体，在其他实施例中，也可以采用一体成型工艺制成。
优选地，扇叶组件202的数量为三个，当三个扇叶组件202均收合时，前一个扇叶结构100的前缘11的靠近扇叶根部1b的一侧与后一个扇叶结构100的后缘12的靠近扇叶端部 1a的一侧相对设置，且该前一个扇叶结构100与后一个扇叶结构100之间形成有间隙，使三个扇叶结构100之间互不交叠。
如图1所示，为了进一步提高扇叶结构100的整体强度，扇叶结构100上还设有第一加强筋15和第二加强筋16，其中，第一加强筋15设于扇叶结构100靠近风扇灯主体201的一侧的长度方向上，并自扇叶根部1b朝向扇叶端部1a延伸形成，且第一加强筋15的宽度逐渐缩小，形成类鱼刺状结构。优选地，第一加强筋15设于弧面14宽度方向的中间区域上，当然，第一加强筋15的具体设置位置及其横断面形状可以根据具体需求进一步限定，本申请对此不做限定。
第二加强筋16设于连接结构2与扇叶根部1b之间，连接结构2通过第二加强筋16与扇叶根部1b固定连接，以加强两者之间的连接强度。可选地，第二加强筋16的数量为多个，且呈环状等间距排列在连接结构2与扇叶根部1b之间，第二加强筋16的具体数量可以根据扇叶结构100的实际尺寸设定，本申请对此不做限定。
风扇灯主体201包括照明组件、转盘30、与转盘30连接的驱动件31、以及悬挂组件。扇叶结构100以相互交错排列的方式设置在转盘30上，能够充分利用转盘30上的有限空间，从而有利于风扇灯200产品的小型化。转盘30既可以实现对于多个扇叶结构100的安装，又可以使得多个扇叶结构100完成同步展开或同步收合动作，还能够限制扇叶结构100的转动角度，从而保证风扇灯200的正常运转。多个扇叶组件202与转盘30连接，可以提供吹风功能。而且，在扇叶结构100处于收合状态时，从观察者的角度看，可以保证扇叶结构100能够被风扇灯主体201的转盘30遮挡，从而提高风扇灯200整体的美观度。
照明组件包括底盘40、集成于底盘40上的光源模块41、与光源模块41电性连接的驱动模块42以及与底盘40固定连接的面罩43，底盘40和面罩43共同形成供收容光源模块41和驱动模块42的收容腔，面罩43配置为将光源模块41的出射光自面罩43射出，以实现照明效果。本申请中，驱动模块42优选为集成在底盘40上，当然，也可以根据实际情况将驱动模块42设置在扇叶组件202或悬挂组件上，只要能够实现驱动模块42对照明组件和扇叶组件202的驱动作用即可。
驱动件31配置为驱动转盘30转动，以带动扇叶结构100相对于转盘30打开或收合。悬挂组件包括吸顶组件50和吊杆51，吊杆51的一端与驱动件31连接，另一端与吸顶组件50连接。照明组件设置在转盘30的下方，照明组件与驱动件31连接，且吊杆51与驱动件31连接，使得照明组件能够稳定地悬挂在屋顶或其他安装面上。
结合图6、图7以及图8所示，本申请的风扇灯200的横截面呈圆形设置，故其面罩43、底盘40以及转盘30均也呈圆形设置。底盘40包括本体部401和围设在本体部401外周边缘处的凸出部402，凸出部402的内侧壁上设有定位部403，面罩43对应设有与定位部403相配合的配合部431，配合部431配置为与定位部403相互配合，以使面罩43和底盘40固定连接。
优选地，定位部403配置为朝向底盘40的中心位置凸出的凸筋，且凸筋403均匀分布在凸出部402的内侧壁上，配合部431配置为自面罩43的外侧壁朝向面罩43的中心位置凹陷，以此通过凸筋403突伸入配合部431来固定底盘40和面罩43。如此设置，能够简化面罩43与底盘40的组装，使得风扇灯200安装更加方便。
如图8至图11所示，进一步地，配合部431环绕面罩43的边缘设置，面罩43包括第一侧壁4310、与第一侧壁4310相对设置的第二侧壁4311以及连接第一侧壁4310和第二侧壁4311的连接壁4312，配合部431由第一侧壁4310和连接壁4312共同形成。第一侧壁4310收容在收容腔内并与凸筋403的上表面相抵接，凸筋403伸入配合部431内并与连接壁4312相抵接，第二侧壁4311与凸出部402相抵接，如此设置，能够减小面罩43与底盘40之间的间隙，不但使得底盘40和面罩43安装后不容易拆卸，而且还能够防止蚊虫进入收容腔内。
进一步地，底盘40上还设有抵接部404，该抵接部404朝向面罩43突伸，用于与连接壁4312的内侧壁相抵接，凸筋403和抵接部404错位设置，并在内外方向上挤压连接壁4312。也就是说，利用错位设置的凸筋403和抵接部404，能够在组装底盘40和面罩43时，使凸筋403和抵接部404在内外方向上对连接壁4312进行挤压，进一步保证面罩43不易从底盘40上脱落，同时在挤压固定的基础上方便组装底盘40和面罩43，且组装好后还不易拆卸。
当然，为了能够使底盘40与面罩43之间连接地更加紧密，上述定位部403与配合部431之间的连接形式可设计成不可拆卸式连接，即利用定位部403和配合部431使得底盘40和面罩43固定连接，这样不但更加保证了面罩43与底盘40之间的间隙达到更小，而且还保证了照明组件中各零部件之间的连接稳定性，不会受人为或环境原因而影响面罩43和底盘40之间的连接稳定性，同时也保护了收容腔内部的结构，以防灰尘和蚊虫等污染物进入收容腔，破坏光源模块41的发光效率，损坏照明组件，影响风扇灯200的使用寿命。
结合图6、图7、图12以及图13所示，底盘40的中间位置处朝向靠近转盘30的方向凹陷形成有用于放置驱动模块42的收容槽405，且该收容槽405与收容腔贯通。光源模块41呈环形设置，且光源模块41环绕收容槽405并与底盘40紧贴固定；光源模块41包括呈环形状的光源板410和均匀分布在光源板410上的LED光源411。如此设置，不仅有效提高了收容腔内的空间利用率，而且驱动模块42不会对光源模块41造成遮挡。
具体地，驱动模块42包括电路板420和用于保护电路板420的盖板421，整个电路板420放置于收容槽405内并与底盘40固定连接，电路板420上集成有多个功能部件，用于调节照明组件的亮度及温度等。盖板421与收容槽405的内侧壁组装固定，以遮盖和保护电路板420。本申请中，盖板421与收容槽405内侧壁的固定方式为卡扣式连接，但不应以此为限，只要能够实现盖板421从底盘40上拆卸下来的目的即可。
进一步地，结合图14所示，驱动模块42还包括若干根电线，盖板421的朝向电路板420一侧突设有第一齿条4210，对应地，底盘40的中心位置处设置有第二齿条4210’，当盖板421与底盘40卡扣固定后，第一齿条4210与第二齿条4210’上下相对设置，并在第 一齿条4210和第二齿条4210’之间形成卡设空间4211，电线卡设在该卡设空间4211内，以此来防止电线组装或使用时产生拉扯。较佳地，本申请中的第一齿条4210呈环形设置并位于盖板421的中央位置处，第二齿条4210’也呈环形设置并位于底盘40的中央位置处，从而多根电线能够集中收容并卡设在第一齿条4210和第二齿条4210’之间，以防电线拉扯，同时还方便安装。
进一步地，在底盘40和电路板420之间还设有用于防止驱动模块42过热的阻燃垫44，该阻燃垫44的两侧分别与底盘40和电路板420固定连接，以防电路板420因工作过程中温度过高而导致自燃。当然，若底盘40的材料中已经含有了阻燃材料，那么底盘40和电路板420之间也可以不设置阻燃垫44，即阻燃垫44的设置与否可以根据底盘40的具体材质而定。
驱动件31与驱动模块42电性连接，从而该驱动模块42能够单独为驱动件31或光源模块41提供电源，以单独启动照明组件或扇叶组件202，也能够同时为驱动件31和光源模块41提供电源，以同时启动照明组件和扇叶组件202。如此，更加有效提高了收容腔的空间利用率，同时也有效减轻了整个风扇灯200的重量。本实施例中，驱动件31为直流电机；当然，在其他实施例中，驱动件31也可以为交流电机，只要能够实现驱动件31驱动转盘30旋转即可，此处不作限制。
结合图6和图15所示，本申请中的驱动件31优选为外转子电机，该外转子电机包括定子和环绕定子的转子，定子与底盘40固定连接，转子与转盘30固定连接。具体地，外转子电机的一端与吊杆51连接、另一端分别穿过转盘30和底盘40，并与底盘40固定连接。如此设置，转盘30能够在转子的带动下相对于底盘40做旋转运动，以使转盘30上的扇叶结构100展开或收合。当然，驱动件31也可以是其他结构的驱动部件，只要能够驱动转盘30相对于底盘40做旋转运动即可，于此不作过多限制。进一步，本申请中的外转子电机尺寸相比于传统的电机，尺寸较小，且较为轻薄，如此设置，当45°仰视整个风扇灯200时，风扇灯200整体看起来更加美观。
本申请的风扇灯200还包括用于检测风扇灯200周围环境温度的温度传感器33，该温度传感器33与驱动件31固定连接，并位于驱动件31的靠近吊杆51的一端。优选地，温度传感器33为具有智能控制作用的温度传感器33，用于实时检测风扇灯200周围的环境温度，并根据当前的环境温度实时的控制扇叶结构100的转速，如：环境温度上升时扇叶结构100的转速增大，环境温度下降时扇叶结构100的转速降低，以此来达到智慧控制的目的。
温度传感器33上套设有保护罩34，该保护罩34呈镂空状设置并与驱动件31固定连接，以起到保护温度传感器33的作用。当然，本申请的温度传感器33也可以设置在其他位置，只要能够实时检测到风扇灯200周围环境的温度即可，于此不作过多限制。
结合图6和图16所示，底盘40与转盘30之间设有加强部45，加强部45配置为与底盘40贴合，且加强部45具有固定部452，该固定部452穿过底盘40并与底盘40固定连接。
如图16至图18所示，具体地，加强部45设于底盘40的中间位置处，底盘40的靠近 转盘30的一侧设有开口方向朝向转盘30的第一槽406，加强部45放置在第一槽406内并与第一槽406的侧壁贴合。第一槽406的中间位置处凹陷形成有第二槽407，加强部45的中间位置处对应设有与第二槽407相配合的突出部450，突出部450贴合放置在第二槽407内；突出部450的中心位置处开设有穿孔451，底盘40上对应开设有与穿孔451相对应的通孔408，固定部452在突出部450上撕裂成型，该固定部452一部分设于穿孔451的边缘处，另一部分围设在穿孔451的旁侧，这些固定部452均朝向底盘40突伸，以穿过通孔408并与底盘40固定连接。
加强部45上形成有与突出部450相背的凹槽453，也就是说，在加强部45上挤压形成凹槽453时，加强部45的另一侧同步向外突出，即形成了突出部450。驱动件31依次穿过穿孔451和通孔408，并与凹槽453的内侧壁相抵接。如此设置，加强部45不但能够加强底盘40的结构强度，以防扇叶组件202旋转时破坏底盘40，而且还能够与底盘40和转盘30配合连接，增大底盘40和转盘30之间的散热面积。
为了进一步加强底盘40的结构强度，加强部45的朝向转盘30一侧形成有凸肋454，该凸肋454均匀分布在加强部45上，且将凹槽453的外壁面和加强部45的外边缘相连。此外，加强部45上还设有定位孔455，底盘40上对应设有与定位孔455相配合的定位筋409，组装时定位筋409伸入定位孔455内，不仅能够起到预安装的作用，而且还能限制加强部45与底盘40之间的晃动。定位孔455设置有多个，主要包括圆孔和腰型孔4550，其中腰型孔4550的设置目的主要是为了防止加强部45与底盘40组装时出现公差，继而易于加强部45与底盘40之间的组装。
结合图6、图10、图15以及图16所示，底盘40靠近边缘处形成有环形槽40A，该环形槽40A的开口朝向转盘30，转盘30的边缘处设有凸边301，底盘40与转盘30组装完成后，凸边301收容在环形槽40A内。具体地，该环形槽40A形成在底盘40的本体部401与凸出部402之间，环形槽40A的底部配置为与面罩43的第二侧壁4311相抵接。本申请中，转盘30与底盘40呈上下叠放设置，驱动件31分别穿过转盘30和底盘40，并使得转子与转盘30固定连接、定子与底盘40固定连接，转盘30的边缘处设有一圈凸边301，该凸边301收容在环形槽40A内，一方面能够使得转盘30和底盘40之间的组装更加美观，另一方面也能够使得凸边301在环形槽40A内转动，对旋转误差能够进行有效的控制，同时还能利用底盘40来遮挡转盘30的旋转。如此，可将转盘30、驱动件31以及底盘40连接为一体，即扇叶组件202与照明组件连接为一体，从而在驱动件31的驱动作用下，转盘30能够相对于底盘40做旋转运动，进而带动扇叶结构100展开或收合。
需要说明的是，悬挂组件除了上述结构以外，还可以参考现有的技术方案进行其他设置，不对悬挂组件的具体结构进行限制。
因本申请的扇叶结构100主要在形状和曲率半径上作出了改进，故以下说明书部分将选用两个样品的测试结果来对本申请的扇叶结构100的吹风效果进行说明。
试验结果
将转速作为唯一变量的两个相同风扇灯200产品作为样品1和样品2，本申请实施例中，样品1的转速为260转/分钟，样品2的转速为270转/分钟，定义多个测量点，样品1和样品2启动时，测试两者的各种性能数据，如试验电压、输入功率和能效值等，测试结果如表1所示。通过测试不同测量点处的风速，比较样品1和样品2的吹风效果，测试结果分别如表2和表3所示。
表1样品1和样品2在运转时测试的各种性能数据
从表1可以看出，在其他条件一致的情况下，由于样品1的转速低于样品2的转速，则样品1的总风量略低于样品2的总风量，这说明，总风量与风扇灯200的转速有关，转速增大，总风量也随之增加。然而，样品1的能效值却略高于样品2的能效值，这说明，相较于样品2而言，样品1更为节能。
表2样品1在不同测量点处风速的测试结果

表3样品2在不同测量点处的风速测量结果

定义测试点靠近风扇灯200的一侧为测试点的前侧，以风扇灯200的中心点为圆心、测试点与风扇灯200的中心轴线之间的距离为圆环半径，此时形成一个圆环。
从表2和表3可以看出，在不同的测试点处，测试到的风速也不同。具体地，整体上看，测试点处(包括测试点的前、后、左和右侧)的风速均与测试点处到风扇灯200的中心轴线的距离先呈现正相关后呈现负相关的趋势。另外，在不同圆环半径处，测试点处最大风速所在的方向呈现无规律的变化，这可能和实际测试环境的空气流动等因素有关。
进一步地，在圆环半径为200米时，样品1和样品2的平均风速均达到最大值，分别为164.34m/min和164.87m/min，两者相差甚微，这可能是由于测试距离较大，受实际空气的流动因素等影响。而圆环半径为360米时，样品1和样品2通过圆环的风量均达到最大值，分别为21.66m3/min和22.66m3/min。这说明，风扇灯200在测试点距离风扇灯200的中心轴线的距离为200米处的吹风效果最好，而风扇灯200在测试点距离风扇灯200的中心轴线的距离为360米处通过圆环的风量最高。可以看出，虽然样品1的转速低于样品2的转速，但是，样品1和样品2的平均风速以及通过圆环的风量均相差较小，也就是说，本申请的扇叶结构100在转速发生变化的情况下，因对其曲率半径进行了改进，使得其吹风效果更佳，不会因转速变化而产生较大的影响。
在圆环半径处于40米处，样品1的平均风速以及通过圆环的风量明显低于样品2，这可能是由于测试点到风扇灯200的中心轴线的距离较近，风速为主要影响因素。从整体上看，当圆环半径处于40～200米之间时，风扇灯200的平均风速和通过圆环的风量随着圆环半径的增大而增大，当圆环半径处于200～920米之间时，风扇灯200的平均风速随着圆环半径的增大而降低，风扇灯200的通过圆环的风量随着圆环半径的增大先增大后降低。当圆环半径超过1000米后，无论是样品1还是样品2，在测试点处均未测到平均风速和风量，这是因为流动的空气在流动过程中会不断受阻力因素影响，使得风力逐渐被削弱，最终归零。在圆环半径为920米处，样品2的平均风速高于样品1的平均风速，这表明在此处，平均风速和样品2的转速高于样品1的转速有关，而此时，测试环境中空气的流动影响较小。
如前所述，本申请提供的风扇灯200产品可以实现大范围吹风，可以应用在车间、仓库等占地大且需要降温的场所中。
综上所述，本申请通过对扇叶结构100的形状和曲率半径进行改进，提高了风扇灯200的整体强度以及吹风效果。
以上仅为本申请的优选实施例而已，并不用于限制本申请，对于本领域的技术人员来说， 本申请可以有各种更改和变化。凡在本申请的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本申请的保护范围之内。
