下面结合图1，说明本实施例的投影装置的工作原理。
在需要进行投影时，将所述切换控制阀103切换到所述导光板102和所述投影组件104之间的开位置，即将所述切换控制阀103从所述导光板102和所述投影组件104之间旋出。此时，所述导光板102将所述发光二极管101发射的光线导入到所述投影组件104，投影组件104以导光板102导入的光线作为光源进行投影。
在关闭投影功能时，将所述切换控制阀103切换到所述导光板102和所述投影组件104之间的关位置，即将所述切换控制阀103旋入所述导光板102和所述投影组件104之间。此时，所述切换控制阀103切断所述导光板102导入所述投影组件的光线，进而断开所述投影组件104的光源，投影组件104不能进行投影。
其中，将所述切换控制阀103切换到所述导光板102和所述投影组件104之间的关位置，所述反射层106将所述导光板102的光线反射回所述导光板102。
在图1所示的实施例中，通过切换控制阀103控制导光板102的光线是否导入所述投影组件104，需要打开投影功能时，通过切换控制阀103控制导光板102的光线导入所述投影组件104，投影组件104以导光板102的光线作为光源进行投影；在需要关闭投影功能时，通过切换控制阀103阻断导光板102的光线导入所述投影组件104，则投影组件104不能进行投影，不仅操作方便，而且节省成本，利于投影设备的推广。
本发明还提供一种投影设备，该投影设备包括图1所示的投影装置，鉴于该装置在上文已有详细的描述，此处不再赘述。
请参阅图3，图3示出了本发明中投影装置的第二较佳实施例的结构。
在图3所示的实施例中，所述投影装置包括发光二极管101，导光板102，切换控制阀103以及投影组件104。
请参阅图3，所述导光板102在沿所述导光板102长度方向的一侧连接所述发光二极管101，另一侧切割为一倒角状，所述倒角状处设置第一反射层301，所述投影组件104对应所述第一反射层，且所述投影组件104的投影方向D2垂直设置于所述导光板102的长度方向。
请参阅图3，所述导光板102和所述投影组件104之间设置有中轴105，所述切换控制阀103连接于所述中轴105，即切换控制阀103可绕所述中轴105旋转，请参阅图2。
在图3所示的实施例中，所述切换控制阀103通过所述中轴105在所述导光板102和所述投影组件104之间的开位置和关位置进行切换：
所述切换控制阀103在所述开位置时，第一反射层301将所述导光板102的光线导入所述投影组件104，以作为所述投影组件的光源；
在图3所示的实施例中，在所述开位置，所述切换控制阀103从所述导光板102和所述投影组件104之间旋出，使得第一反射层301将所述导光板102的光线反射至所述投影组件104。
在所述关位置时，所述切换控制阀103切断所述导光板102导入所述投影组件104的光线，进而断开所述投影组件104的光源。
在图3所示的实施例中，在所述关位置，所述切换控制阀103旋入所述导光板102和所述投影组件104之间，使得第一反射层301将不能将所述导光板102的光线反射入所述投影组件104。
在本实施例中，所述切换控制阀103为旋转阀门结构，当然，所述切换控制阀103也可以是其它的结构，譬如为不透光的长条状，直接插拔于所述导光板102和所述投影组件104之间，只要能够控制导光板102的光线是否导入到所述投影组件104即可，此处不一一列举。
请参阅图3，所述导光板102在所述倒角状一侧保留一短侧边，所述短侧边垂直于所述导光板102的长度方向，所述短侧边设置有第二反射层302，所述第二反射层202将来自导光板102的光线反射回所述导光板102。
其中，所述投影组件104用于实现投影，其包括透镜、焦距调节器等器件，此处不一一列举。
下面结合图3说明本实施例的投影装置的工作原理。
在需要打开投影功能时，将所述切换控制阀103切换到所述导光板102和所述投影组件104之间的开位置，即将所述切换控制阀103从所述导光板102和所述投影组件104之间旋出。此时，所述第一反射层301将所述导光板102导入的光线反射到所述投影组件104，投影组件104以所述第一反射层301反射的光线作为光源进行投影。
在需要关闭投影功能时，将所述切换控制阀103切换到所述导光板102和所述投影组件104之间的关位置，即将所述切换控制阀103旋入所述导光板102和所述投影组件104之间。此时，所述切换控制阀102切断所述第一反射层301反射入所述投影组件104的光线，进而断开所述投影组件104的光源，投影组件104则不能进行投影。
在图3所示的实施例中，通过切换控制阀103控制导光板102的光线是否导入所述投影组件104，需要打开投影功能时，通过切换控制阀103控制第一反射层301将导光板102导入的光线反射至所述投影组件104，投影组件104以第一反射层201反射的光线作为光源进行投影，在需要关闭投影功能时，通过切换控制阀103阻断第一反射层301的光线反射入所述投影组件104，则投影组件104不能进行投影，不仅操作方便，而且节省成本，利于投影设备的推广。
本发明还提供一种投影设备，该设备包括图3所示的投影装置，鉴于该装置在上文已有详细的描述，此处不再赘述。
综上所述，虽然本发明已以优选实施例揭露如上，但上述优选实施例并非用以限制本发明，本领域的普通技术人员，在不脱离本发明的精神和范围内，均可作各种更动与润饰，因此本发明的保护范围以权利要求界定的范围为准。
