 本发明的实施方式
为了使本发明所解决的技术问题、技术方案及有益效果更加清楚明白，以下结合附图及实施例，对本发明进行进一步详细说明。应当理解，此处所描述的具体实施例仅仅用以解释本发明，并不用于限定本发明。
本发明是通过以下技术方案实现的：
    如图1至图7所示，具有静音大风量风道结构的照明装置，包括外壳体1以及灯壳2，所述灯壳2上设有发光部4，所述灯壳2嵌入安装在外壳体1的端面上且灯壳2外周与外壳体1内侧之间的缝隙形成出口朝向该端面的出风通道31，所述灯壳2上还设有进风口32以及设于进风口32内的吸风部件33，所述出风通道31的截面形状包括自内向外宽度逐渐减少的加速风道31a以及连接在加速风道31a末端与外界连通的喇叭状开口31b。本发明提供了具有静音大风量风道结构的照明装置，其通过将无叶风扇的结构融入到灯壳上，使得即有照明功能，又满足了吹风的需求，同时也解决了风扇灯尺寸大、易产生噪音的问题。而且使得本产品不受限应用于在吊灯上，可作为壁灯、吸顶灯等灯具上使用，能够代替掉更多场合的风扇使用。而且出风风道作出了优化设计，通过加速风道以及喇叭状开口吹出的风具有风量大，而且角度广、静音的特点，满足使用者的需求。
    具体地，所述喇叭状开口31b与加速风道31a呈夹角设置。又具体地，所述喇叭状开口31b与加速风道31a之间的夹角为150°至170°。使从加速风道吹出的风作出变向，而且通过喇叭状开口能使其吹出的角度更广。
    另外，所述加速风道31a的宽度满足d=D-0.13L；
    其中，d为加速风道末端的宽度，D为加速风道起始端的最大宽度，L为加速风道起始端至末端的长度。经过多次优化迭代不断调整加速风道的宽度以及长度后，并考虑实际制造时的难度，最终得到合理的长度和宽度范围为：
    所述加速风道31a起始端的最大宽度D为3~6mm。本申请中选取4.8mm。
    所述加速风道31a的长度L为10~20mm。本申请中选取13mm。
    采用上述尺寸合理设计，在出风道形成口径越来越窄的缝状加速风道，使得从该出风道吹出的风呈高速喷射，从而使本产品四周的空气向高速射流流动，根据伯努利方程可知高速气流的静压相对于周边空气的静压低，从而使周边空气向高速射流流动，从而实现流量倍增的效果（流量增加的倍数与射流速度相关）。而且其风量相比普通的无叶风扇更大，静音效果更好。
    又进一步地，所述外壳体1下端面设有向上凹陷的内空腔101，所述灯壳2设于内空腔101内，所述灯壳2的下端也设有向上凹陷的凹腔201，所述发光部设于所述凹腔201内，所述发光部包括设于凹腔201内的发光单元、以及覆盖在凹腔201下端开口的导光板。其在灯具上结合无叶风扇的结构，同时满足了出风以及照明的功能，又解决了吊扇灯难清洗、存在安全隐患的问题。而且，本方案中，出风通道以及进风口是位于同一端面上，通过发光部相隔开，可以理解为从光照的方向进行吸风以及进风，从而本产品并不受限于应用在吊灯上，可作为壁灯、吸顶灯等灯具上使用，能够代替掉更多场合的风扇使用。使得本产品使用范围更广，使用更加灵活。另外，灯壳或外壳体内还设有驱动器，通过驱动器可实现照明功能、风扇功能的单独启动或同时启动。使本产品使用更加灵活。
    而且，本方案中，外壳体1的厚度（即上端面到下端开口的距离）为45~70mm，整体轻薄，而且灯壳采用嵌入式安装，使产品整体安装完后整体尺寸小。且从附图中可看出，本产品做成圆扁型，其整体结构紧凑，而且轻薄。
    另外，灯壳嵌入安装后，与内空腔形成间隙，从而形成进风口-空腔间隙-出风通道的流动通道，利用吸风部件从进风口处将空气从外部吸入，并经过加速后从出风通道吹出，利用无叶风扇的原理，而且结合在照明灯具上，使得产品功能更全，而且结构简单，尺寸小。
再进一步地，所述进风口32设于灯壳2的中部且与外壳体1的内空腔101连通，所述吸风部件33包括设于进风口32内的吸风风扇，所述吸风风扇包括叶片基座331以及多个呈圆周式均匀分布在所述叶片基座331上的叶片332，所述叶片的叶尖与所述叶片基座中心轴线的夹角α为33.5°~37.3°，所述叶片的叶根与所述叶片基座中心轴线的夹角β为52°~58°。通过改进叶片在叶片基座上的叶根安装角和叶尖安装角，则在同等尺寸、同等电动率输入的情况下，使该叶型设计相比于传统风机叶型设计，具有体积小、重量轻、效率高、叶片处流通风量大的特点，使该风扇叶组件可广泛用于各种通风设备中，使通风设备结构简单，体积小、重量轻和风量大。
又具体地，叶尖安装角α：33.5°~37.3°；专利里选取35°。叶根安装角β：52°~58°；专利里选取55°。通过这样的叶型设计，在同等尺寸、同等电功率输入的情况下，风扇效率至少可以提升5%；或者，在同等尺寸和功率输入的情况下，新构型风机可以比传统动力风机的风量至少增加5%。
    另外，所述进风口32处还设有隔尘罩321。有利于防止外部灰尘、颗粒进入到本产品内部，造成堵塞、损坏等问题。另外还可设置用于过滤空气中的杂质或清新空气的过滤装置，来达到空气过滤以及使吹出的气流更清新。
    本方案中，所述外壳体1的上端面还设有安装部6所述安装部6上连接有用于固定连接在外界上的安装座61，所述安装座61可拆卸连接在所述安装部6上。安装座用于固定在外界的连接物上，比如墙壁，梁柱等。本方案采用安装座61可拆卸连接在所述安装部6上，其可根据不用的连接要求更换不同的安装座，使得本产品使用范围更广。
本发明提供了具有静音大风量风道结构的照明装置，其通过将灯壳嵌入安装后，与内空腔形成间隙，从而形成进风口-空腔间隙-出风通道的流动通道，利用吸风部件从进风口处将空气从外部吸入，并经过加速后从出风通道吹出，利用无叶风扇的原理，而且结合在照明灯具上，使得产品使得即有照明功能，又满足了吹风的需求，同时也解决了风扇灯尺寸大、易产生噪音的问题。而且使得本产品不受限应用于在吊灯上，可作为壁灯、吸顶灯等灯具上使用，能够代替掉更多场合的风扇使用。而且出风风道作出了优化设计，通过加速风道以及喇叭状开口吹出的风具有风量大，而且角度广、静音的特点，满足使用者的需求。
如上所述是结合具体内容提供的一种或多种实施方式，并不认定本发明的具体实施只局限于这些说明。凡与本发明的方法、结构等近似、雷同，或是对于本发明构思前提下做出若干技术推演，或替换都应当视为本发明的保护范围。
