具体实施方式
下面将结合本实用新型实施例中的附图，对本实用新型实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本实用新型一部分实施例，而不是全部的实施例。基于本实用新型中的实施例，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，都属于本实用新型保护的范围。在不冲突的情况下，下述的实施例及实施例中的特征可以相互组合。
需要说明的是，在本实用新型中，当一个组件被认为是与另一个组件“相连”时，它可以是与另一个组件直接相连，也可以是通过居中组件与另一个组件间接相连。
除非另有定义，本文所使用的所有的技术和科学术语与属于本实用新型的技术领域的技术人员通常理解的含义相同。本文中在本实用新型的说明书中所使用的术语只是为了描述具体的实施例的目的，不是旨在于限制本实用新型。
请参阅图1所示，本实用新型第一实施方式提供一种投影设备100，其包括光源装置110、信号接收部120、图像处理部130、光调制装置140、主控芯片150及用户操作部170。当然，投影设备100还包括壳体、散热风扇、投影单元等必要或非必要结构，为节省篇幅，在此不做赘述。
光源装置110包括光源113、光转换单元115及光源驱动电路117。光源113，用于发出照明光束。光源113可以是通常的灯，或包括激光器或发光二极管(LED)的固态光源。对于固态光源，其光的波长的典型范围是从300nm到500nm。可以理解，所述光源装置110可以为混合光源，例如，所述光源装置为激光器及发光二极管的混合阵列。所述光源装置110还可以省略光转换单元115。
光转换单元115设置在光源113的出射光的传输路径中，其能够吸收光源113发出的激发光并出射受激光。本实施例中，光转换单元115为一色轮，至少两种不同的波长转换材料分段式位于色轮上。其中，至少两种不同的波长转换材料为吸收光源113出射的激发光后出射至少两种不同的复合光的波长转换材料。吸收光源113出射的激发光后可出射至少两种不同的复合光的波长转换材料为青色荧光粉和黄色荧光粉，或者品红荧光粉和青色荧光粉，或者品红荧光粉和黄色荧光粉。
具体地，分段式色轮可以为包括两种不同的波长转换材料的两段式色轮。例如，分段式色轮包括具有黄色和蓝色或者黄色和青色的两段式色轮。分段式色轮也可以为包括三种不同的波长转换材料的三段式色轮。例如，分段式色轮包括具有青色、绿色和黄色的滤光区的三段式色轮。具体来说，当光源113为蓝光激光光源时，吸收光源113出射的激发光后可出射至少两种不同的复合光的波长转换材料为青色荧光粉和黄色荧光粉；当光源113为UV光源时，吸收光源113出射的激发光后可出射至少两种不同的复合光的波长转换材料为青色荧光粉和黄色荧光粉，品红荧光粉和青色荧光粉，或者品红荧光粉和黄色荧光粉。本实施例中，由于黄光可以分出红色光和绿色光，青色光可以分出黄色光和蓝色光，因此两段式色轮和三段式色轮中的不同的波长转换材料并不限于上述的不同颜色的滤光区。另外，光转换单元115也不限定能发出红色光、绿色光和蓝色光，其只需能发出光即可。
进一步地，为了实现更宽范围的色域调制，本实用新型中的光转换单元115还包括：与色轮同轴旋转的分段式滤光片轮，分段式滤光片轮具有至少两种不同颜色的滤光区。例如，分段式滤光片轮包括具有蓝色、黄色、绿色或者蓝色、黄色、红色或者蓝色、第一黄色、第二黄色的滤光区的分段式滤光片轮，用于对分段式色轮的出射的光进行滤光以得到所需的包括红色、绿色、蓝色的三基色光，从而提高光效和亮度。

当投影设备100处于显示画面的情况下，即所述光源113输出照明光束的情况下，若用户对所述用户操作部170进行了操作，所述用户操作部170响应用户操作而产生一黑屏开启指令并将所述黑屏开启指令传送至所述主 控芯片150。所述主控芯片150接收所述黑屏开启指令，所述主控芯片150依据所述黑屏开启指令生成关闭电源指令，并将所述关闭电源指令发送给所述光源驱动电路。所述光源驱动电路117依据所述关闭电源指令关闭所述光源113中断所述照明光束的输出，进而使所述投影设备100进入黑屏状态不显示画面。所谓的黑屏状态是指，所述投影设备100虽处于工作状态，然不显示画面，如光转换单元115依然在转动，投影设备100的散热风扇依然在进行散热，换句话说，仅光源113被关闭不出射所述照明光束，投影设备100仅不显示画面，投影设备100的其它功能模组依然在进行工作。
所述投影设备100处于黑屏状态时，若用户按压所述用户操作部170，所述用户操作部170响应用户的操作并产生一黑屏关闭指令，所述用户操作部170将所述黑屏关闭指令传送至所述主控芯片150。所述主控芯片150接收所述黑屏关闭指令，所述主控芯片150依据所述黑屏关闭指令产生一开启电源指令并发送给所述光源驱动电路117。所述光源驱动电路117依据所述开启电源指令开启所述光源113恢复所述照明光束的输出，进而使所述投影设备100恢复画面显示。
使用时，所述投影设备100的信号接收部120与所述外源设备101连接，其能够接收所述外源设备101的视频信号。所述外源设备101在对所述视频源数据进行播放时，所述投影设备100的播放速度、播放进度与所述外源设备101保持一致。当然，所述外源设备101并不限定于播放视频，其也可以为幻灯片文件、pdf文件等。当对所述外源设备101进行暂停处理时，所述投影设备100播放的画面亦进入暂停状态；当对所述外源设备101进行快进或回退操作时，所述投影设备100亦进入快进或回退状态。总而言之，通过对所述外源设备101对所述视频源数据进行播放速度、播放进度等的控制，实现所述投影设备100的播放进度或播放速度等控制。而所述用户操作部170响应预定的用户操作产生黑屏开启指令时，所述投影设备100虽进入黑屏状态不显示画面，但不会对所述目标文件的播放进度或播放速度造成影响。而所述用户操作部170响应用户操作产生黑屏关闭指令时，所述投影设 备100显示画面，所述投影设备100显示的画面与所述外源设备101显示的画面一致。
