具体实施方式
下面结合附图对本发明作更进一步的说明。
如附图1-2所示，本发明之LED智能照明灯具(以下简称：“灯具”)包括固定灯罩1、旋转灯罩2、弹性遮罩膜3、伸缩罩4、反光罩5、LED灯板6；其中：
固定灯罩1由光面透光材料制成，其为中空且下端封口的圆筒状；
旋转灯罩2由光面透光材料制成，其也为中空且下端封口的圆筒状；其安装在所述固定灯罩1内并可相对于所述固定灯罩1旋转；
弹性遮罩膜3由亚面透光材料制成，且其置于所述固定灯罩1与旋转灯罩2之间，其由所述旋转灯罩2下端面的中心沿着下端面的径向延伸至所述旋转灯罩2的侧壁部分并沿着侧壁部分的母线延伸；其两侧分别固定在所述固定灯罩1与所述旋转灯罩2上；所述弹性遮罩膜3可随着所述旋转灯罩2的转动在展开状态(如附图4所示)与缩回状态(如附图3所示)之间切换；本实施例中，所述弹性遮罩膜3有多个，所有所述弹性遮罩膜3以所述旋转灯罩2的旋转中心为中心圆周阵列分布，如此可减少对弹性遮罩膜3弹性的要求。当弹性遮罩膜3处于展开状态时，如附图4所示，处于旋转灯罩2的下端面位置的弹性遮罩膜3展开为扇形，处于旋转灯罩2的侧壁部分的弹性遮罩膜3展开为弧形片状，所有的处于展开状态的弹性遮罩膜3拼合为一个中空且下端分别的圆柱形遮罩面。
伸缩罩4由不透光材料制成，其为下端未封口的圆筒状，其置于所述旋转灯罩2内，并可相对于所述固定灯罩1升降，且其升降运动可使所述旋转灯罩2相对于所述固定灯罩1转动；为了实现灯具形态的自动切换，伸缩罩4相对于固定灯罩1的升降运动由执行元件7驱动，执行元件7可以是电动推杆的可驱动物体作直线运动的原动件。
反光罩5内具备碗状反光面51，且其相对于所述伸缩罩4固定安装。当LED灯板6置于所述反光罩5内时，由于反光面51的反光作用，可将LED灯板6发出的灯光反射为平行光并从固定灯罩1的端面射出。
LED灯板6相对于所述固定灯罩1固定。
基于上述结构，灯具可呈现两种形态，下列分别说明如下：
第一种形态：射灯形态，如附图1所示，此时，弹性遮罩膜3处于收缩状态，伸缩罩4位于固定灯罩1的下侧，伸缩罩4将固定灯罩1侧壁部分的下端遮盖住使得固定灯罩1侧壁部分无法透出灯光；同时，当伸缩罩4位于固定灯罩1的下侧时，LED灯板6置于反光罩5内，反光罩5内的反光面51将LED灯板6发出的灯光反射为平行光并从固定灯罩1的端面射出。
第二种形态：柔光灯形态，如附图2所示，此时，相对于第一种形态，执行元件7使伸缩罩4作上升运动至高位，伸缩罩4上升时，逐渐解除对固定灯罩1的侧壁下侧的遮挡，使得固定灯罩1侧壁下侧可有灯光透出；另外，伸缩罩4上升带动反光罩5上升，伸缩罩4上升至最高点后，LED灯板6置于反光罩5外，此时，LED灯板6发出的灯光可四处发散；同时，伸缩罩4上升时，其平移运动使得旋转灯罩2产生转动，当伸缩罩4运动至最高点，弹性遮罩膜3切换为展开状态，所有的处于展开状态的弹性遮罩膜3拼合为一个中空且下端分别的圆柱形遮罩面，圆柱形遮罩面将固定灯罩1的可有灯光透出的面全部遮住，如此，LED灯板6发出的灯光透过圆柱形遮罩面再透出至固定灯罩1外，使得灯光不刺眼，且可四处发散。
通过上述方式，可使得灯具可在两种形态之间灵活切换。
优选地，为了实现伸缩罩4的运动与旋转灯罩2运动的联动，如附图5所示，所述旋转灯罩2的内壁上形成有倾斜延伸的导引槽21；所述伸缩罩4上形成有导引柱41，所述导引柱41置于所述导引槽21内，并可沿所述导引槽21运动。如此，当伸缩罩4作上升运动，导引柱41沿着导引槽21运动，由于导引槽21倾斜运动，因此，当导引柱41上升，可使得旋转灯罩2旋转，结构简单，如此，只需要执行元件7一个原动件即可实现伸缩罩4及旋转灯罩2两者的同步运动。
此外，为了实现LED灯板6的散热，所述固定灯罩1的顶部安装有封盖8，所述LED灯板6安装在铜座9上，所述铜座9与所述封盖8之间设置有铜管10，所述铜管10的上端设置有散热鳍片101；所述封盖8上形成有散热孔81。
另外，所述固定灯罩内还安装有控制器20。控制器20连接LED灯板6以及执行元件7，用户通过实体开关或手机APP等形式向控制器20发送信号可控制灯具的亮灭及灯具形态的转变。
本发明的LED智能照明灯具，通过设置弹性遮罩膜，相对于固定灯罩转动安装的旋转灯罩，以及相对于固定灯罩伸缩设置的伸缩罩，通过驱动所述伸缩罩相对于所述固定灯罩移动，使得灯具可在射灯形态与柔光灯形态之间切换，满足不同场景的使用需求，用户无需再同一空间内安装射灯与柔光灯两种灯。
以上所述仅是本发明的优选实施方式，应当指出：对于本技术领域的普通技术人员来说，在不脱离本发明原理的前提下，还可以做出若干改进和润饰，这些改进和润饰也应视为本发明的保护范围。
