参见图1至图7所示，壳体1呈盖状，其由绝缘材料一体成型而成，包括半圆形的主体部110及位于该主体部顶部的连接部120，连接部120用于与灯头3结合。于本发明的优选实施例中，灯头3与该连接部120通过各自设置的内螺纹及外螺纹进行螺纹连接。于其他优选实施例中，灯头3也可与壳体1一体成型，比如采用包覆成型的方式。壳体1的外周壁上形成有若干个第一端口11，通过第一端口11，壳体1内部的空间可以与照明装置100的外部连通。第一端口11为弧形，若干个第一端口11以环形的形式排列于所述主体部110的外周壁，排列为两个同心环，加强了壳体1内部的空间与照明装置100的外部连通。在其它实施方式中，第一端口11可以排列为单环或多环的形式，第一端口11还可以为其它形状及排列为其它形式。壳体1的主体部110的侧壁内表面上凸设有若干定位柱12和第一卡槽13，用于定位光源组件4和导流板6，及若干个第一凸肋14和第二凸肋15，用于与光学元件2连接及导流板6的定位。定位柱12间隔设置于第一端口11之间并沿所述安装方向延伸为条形，定位柱12内设有第一定位孔121。第一卡槽13位置高于定位柱12，并临近连接部120。第一凸肋14设置于主体部110的下端缘内侧并沿该下端缘周侧间隔排布，而第二凸肋15则为沿安装方向延伸的条形结构并间隔设置。
光学元件2采用中空的长椭圆形的泡壳，其由塑料等绝缘材料一体成型。光学元件2与壳体1连接的一端凸设有一圈卡持部21，卡持部21与第一凸肋14卡扣连接。于其他优选实施例中，光学元件2与壳体1的卡扣连接结构可以互换。光学元件2的另一端为大致呈一平台的端部220，其具有一定的厚度，其连接于光学元件2外径渐缩的椭圆形侧壁的另一端。由端部220的内表面间隔开设有若干第一开口22，因此形成有导流部23，于本发明优选实施方式中，导流部23由间隔设置于相邻第一开口22之间的若干筋条231构成。通过第一开口22，壳体1内部的空间可以与照明装置100的外部连通。第一开口22为三角柱状，若干个第一开口22以圆周阵列的形式排列于端部220，排列为一个多边形。第一开口22所形成的最大外径尺寸小于第一端口11形成的最大外径尺寸。在其它实施方式中，第一开口22还可以为其它形 状及排列为其它形式。光学元件2也可以采用TIR透镜、COB透镜、或是泡壳样式的匀光罩、或是透镜和泡壳结合的方式，对于环形的光源，光学元件也可以对应设置为环形。
如图4和图5所示，光源组件4包括沿垂直于所述安装方向的水平面延伸形成的圆形的第一基板41、卡接于第一基板41并沿所述安装方向延伸的若干第二基板42、设置于第二基板42上的光源43、及固定第二基板42的固定环45。第二基板42主要靠上、下方向上的第一基板41及固定环45固定。第一基板41呈圆形，第一基板41和光学元件2围设形成容纳光源43的光学腔(未标示)。第一基板41上设有两个用于定位的第二定位孔411，及用于卡接第二基板42并设置于第一基板41中部的第一通孔412，其呈多边形构形。第一基板41的水平面延伸方向的空余位置上，也可以设置光源43。在本发明实施方式中，设置有六条第二基板42，第二基板42卡接在第一通孔412内的卡槽(未图示)内并具有延伸超过该第一通孔412的第一部分421、及设置光源43的第二部分422，该第二部分422的延伸端的侧壁与光学元件2的第一开口22的侧壁贴合，即卡置于第一开口22内。第二基板42与第一基板41呈垂直设置，围成一个六边形的管道44，作为中空的散热通道，光源位于管道44的外侧。在本实施例中，光源43采用LED光源，每个第二基板42上设有一组竖向排列的LED发光单元431，其中，LED发光单元431可以发出白光(W)、红光(R)、蓝光(B)或绿光(G)中的任意一种。在其它实施方式中，光源可以采用TL等其它光源。
固定环45卡接于第二基板42延伸向光学元件2的延伸端并放置于光学元件2的端部内表面上，用于固定第二基板42。在本实施例中，固定环45由塑胶材料制成，呈六边形，且六边形内部形成有六个栅格451，栅格451连通第一开口22与管道44。在其它实施方式中，固定环45还可以为其它任何形状。
驱动电源组件5包括若干元器件，包括但不限于LED驱动控制器芯片、整流芯片、电阻器、电容器、保险丝和线圈等，驱动电源组件5与光源组件4电性连接且一体式设置，分别安装在第一基板41的两侧。在其它实施方式中，驱动电源组件5与光源组件4也可以在第一基板41的同侧设置，或者驱动电源组件5还可以环绕设置于第二基板42的 外侧，或者驱动电源组件5和光源组件4还可以分体设置，分别固定在壳体1内。
导流板6呈圆形，设置于壳体1和光源组件4之间，且定位于壳体1上。导流板6上设有一个多边形的第二通孔61，第二通孔61连通管道44和第一端口11。第二通孔61上设有若干个卡接第二基板42延伸超过第一基板41的第一部分421的第二卡槽62，及两个用于定位的第三定位孔611。在本实施例中，导流板6由塑料等绝缘材料制成。
该照明装置100内，光源组件4的六条第二基板42卡接穿过第二卡槽62后，其第一部分421的端部收容在壳体1的第一卡槽13内，实现光源组件4与导流板6、及壳体1之间的定位。该照明装置100还包括两个螺钉(未图示)，利用螺钉穿过第一基板41的第二定位孔411、导流板6的第三定位孔611并收容在壳体1的第一定位孔121，且第一基板41抵接在若干条第二凸肋15形成承接面(未标示)，从而实现将光源组件1、导流板6、及壳体1固定连接。在其它实施方式中，也可以采用其他连接方式，例如粘接，或卡扣连接，或者焊接。
结合图7所示，本发明实施例的照明装置100内的发热源为光源43及驱动电源组件5，设置若干将其内部与外部连通的通道8，利用通道8可以实现照明装置100的外部空气与内部空气进行对流散热。第一开口22、管道44、第一端口11形成对流的通道8。该照明灯具100工作时，第一开口22为入风口，冷空气进入，流经管道44，最后在导流板6的作用下流出第一端口11，第一端口11为出风口。光源43发光产生热量，通道8内的空气受热，密度变小，产生向上的浮力，空气经过对流通道8，在导流板6的作用下快速流出出风口。同时，驱动电源组件5位于出风口附近，产生的热量使得对应位置的空气急速升温，加强了空气的对流效果，从而使得烟囱效应效果加强。入风口尺寸、散热通道横截面积，出风口尺寸和发热源位置合理设计，极大的加速了空气流动效果，使得对流效果成倍增强，使得温度降低15℃以上。光源43及驱动电源组件5的温度下降，提高了该照明灯具的可靠性及寿命。该通道8由第二基板42的最大表面积围设形成，充分接触散热。
该照明装置，不另外设置散热结构，省去了散热结构的成本，通过合理的结构设计，快速有效散热，解决了灯具散热困难的问题。
综上所述，该照明装置100具有散热效果好的特点，从而延长了照明装置100内光源组件4的使用寿命。另一方面，由于各组件材质都较轻，从而降低了整个照明装置100的重量。
以上所述的具体实例，对本发明的目的、技术方案和有益效果进行了进一步详细说明，所应理解的是，以上所述仅为本发明的具体实施例而已，并不用于限制本发明，凡在本发明的精神和原则之内，所做的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
