为使本发明的目的、技术方案和优点更加清楚，下面将结合本发明具体实施例及相应的附图对本发明技术方案进行清楚、完整地描述。显然，所描述的实施例仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，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，都属于本发明保护的范围。
请参照图1至图3所示，本发明的第一较佳实施例的一种LED照明装置1，包括壳体10、光源装置20、位于光源装置20上方并为其进行配光的光学透镜30、与光学透镜30接触的反射器40以及组设于反射器40的面环50，壳体10、光源装置20、光学透镜30、反射器40、面环50依次排列。面环50固定于壳体10从而围成一收容腔70，光源装置20、光学透镜30、反射器40都位于收容腔70内。LED照明装置1具有一出光口60，光源装置20包括光源板201和位于所述光源板201上的LED光源颗粒202，LED光源颗粒202的光线通过光学透镜30、反射器40后射出出光口60。本发明提供的LED照明装置1不需要扩散板来匀光，就可以使得LED照明装置1射出的光线均匀没有炫光，从而有效的提高光效。
在本发明的可选实施例中，光源装置20可以与光学透镜30卡接。

在本发明的可选实施例中，光源装置20直接面对出光口60时，LED光源颗粒202射出的光线部分直接射出出光口60，部分经过反射器40的反射后射出出光口60，当LED光源颗粒202射出的光线经过光学透镜30后，先经过反射器40的反射后再射出LED照明装置1的出光口60。
在本发明的可选实施例中，LED照明装置1还可以包括设置于壳体10外围的卡簧部80，利用卡簧部80与壳体10配合可以将LED照明装置1安装至例如天花板、墙壁等区域，或是直接安装至照明设备内，以使得LED照明装置1对准照明设备所在区域。本发明实施例提供的LED照明装置可以为筒灯等，本发明对此不作限制。
