具体实施方式
为使本发明实施例的目的、技术方案和优点更加清楚，下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本发明一部分实施例，而不是全部的实施例。通常在此处附图中描述和示出的本发明实施例的组件可以以各种不同的配置来布置和设计。
因此，以下对在附图中提供的本发明的实施例的详细描述并非旨在限制要求保护的本发明的范围，而是仅仅表示本发明的选定实施例。基于本发明中的实施例，本领域普通技术人员在没有作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。
应注意到：相似的标号和字母在下面的附图中表示类似项，因此，一旦某一项在一个附图中被定义，则在随后的附图中不需要对其进行进一步定义和解释。
在本发明的描述中，需要说明的是，术语“中央”、“上”、“下”、“内”、“外”等指示的方位或位置关系为基于附图所示的方位或位置关系，或者是该发明产品使用时惯常摆放的方位或位置关系，仅是为了便于描述本发明和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本发明的限制。此外，术语“第一”、“第二”等仅用于区分描述，而不能理解为指示或暗示相对重要性。
目前存在的大屏幕显示系统中比较典型的是DLP拼接屏，DLP拼接屏是采用DLP显示单元拼接的方式，通过大屏幕拼接软件系统，来实现大屏幕显示效果的一种方式。而现有的DLP拼接屏系统中的DLP显示单元均由每DLP显示单元所自带的独立的电源模块供电，因此，一套DLP拼接屏系统中将会由对个自带的独立电源模块的DLP显示单元所组成，由此一套DLP拼接屏系统将会有多个电源模块。现有的供电系统的电源模块与投影光机集成一起，当电气隔离失效时人体接触到产品壳体会对人体造成伤害，并且电气隔离会导致产品的体积 相对加大，对于安装环境有一定的限制。另外，现有的供电系统，多台协同工作时，需要对应有相应数量电源一起工作，整体利用率不高，造成资源的浪费。传统的拼接技术中单个投影机标配一个电源模块，多台做拼接时，对应电源模块有对应数量，拼接整体的电源可靠性由每个分离电源共同构成，失效因素增多，加大产品风险点。同时电源模块与投影光机集成一起，多台协同工作，电源模块增多，有些功能可以集成控制，变成分离的多台电源一起完成，相对成本也在增加。
因此为了克服上述缺陷，本申请实施例提供了如图1所示的供电系10，该供电系10可以包括电源模块100和多个投影单元，每个投影单元包括投影光机200，电源模块100分别与每个投影光机200连接，用于为每个投影光机200供电。作为一种实施方式，投影光机200和电源模块100是分离的，如图2所示，投影光机200和电源模块100可以通过线材300进行连接，则电源模块100通过线材300为投影光机200供电。
因此，本实施例中电源模块100采用集成设计和投影光机200分离，相较于现有技术中，电源模块100和投影光机200集成在一起，当电气隔离失效时，电源模块100的高压部分很有可能会对人体造成伤害，本申请实施例的电源模块100为电源集成模块，电源模块100对投影光机200输出电压的不会超过42.4V交流峰值或60V直流值，即投影光机200符合国标中的III类设备要求，因此，本申请实施例中人体可以直接接触投影光机200而不造成伤害。另外，现有技术中，当进行屏幕拼接时，每个投影机都需220V的电压供电，导致高压电源布满整个屏幕区域，可能会造成很多隐患，而且投影机体积较大，不利于狭小空间的安装，而本申请电源采用了集成设计，将各个拼接电源中的电源集成在一个功率足够大的独立的电源模块100上，每个投影单元中只需要放置投影光机200即可，这些投影光机200由集成后的电源模块100统一供电，在对这些投影光机200进行供电时供电电压不超过60V，都为安全电压，即整个供电系统10的电压加起来都不会超过高压220V。本实施例的设计可以大大提升系统的安全 性能，另外，投影光机200不需要和电源模块100进行高压隔离使得整个系统体积缩小，电源集成后，整个系统只有一个电源模块100，可靠性也大大提升。
请参阅图1，电源模块100外接220V交流电，能够将该220V交流电转换为各个投影单元内的投影光机200所需要的供电信号，具体地，请参阅图3，以电源模块100为一个投影光机200供电为例，该投影光机200包括主板模块201、光源模块202、成像模块203和第一电压输出端口204。
主板模块201通过恒压输出端口102与电源模块100进行连接并获取电源，本实施例中主板模块201和控制器均可以与恒压输出端口102连接，这些设备之间的连接可以是并联的，故对恒压输出端口102的数量没有限制，例如，一个恒压输出端口102可以同时连接一个主板模块201和一个控制器。则主板模块201和控制器可以同时连接一个恒压输出端口102，则主板模块201和控制器为一个并联的关系，即一个恒压输出端口102可以同时为一个主板模块201和一个控制器供电。
电源模块100为主板模块201提供的是恒压信号，所述恒压信号的电压值的范围一般为28V至45V。
光源模块202用于提供光源并对所述光源发出的光进行调整之后照射到成像模块203。所述光源模块202可以由光源、透镜、棱镜、反光镜镜、导光棒、遮光片和支撑结构等元件组成。光源模块202通过恒流输出端口103与电源模块100进行连接并获取电源，电源模块100为光源模块202提供的是恒流信号，所述恒流信息号的电压值一般为12V。光源模块202可以用于为整个供电系统10提供光源，常用的光源有灯泡光源、LED光源和激光光源，灯泡光源常见的主要为金属卤素灯、UHE灯、UHP灯，金属卤素灯的成本较低，寿命在1000到2000小时不等，相对较短，长期使用后会出现衰减；UHE灯和UHP灯同属于超高压汞灯，亮度高、衰减低、性能稳定，两者的区别在于，UHE灯的成本、寿命适中，多用于中低档投影仪，UHP的成本较高，亮度更高，寿命更长久。LED光源为一种节能环保的光源，和灯泡光源相比其稳定性好、寿命长以及色彩饱和度高等， 另外使用LED光源的投影仪，其投射画面色彩纯正丰富，饱和度、对比度也高于灯泡光源。激光光源为一种新型光源，其主要是利用光电效应使激发态粒子在受到激辐射的作用下发光，激光光源的对比度、饱和度、表现力都远超于灯泡光源，但是激光光源的最大缺点就是成本太高，光源模块100具体使用哪种光源这里不做明确限制用户可以根据需求进行选择。
本实施例中投影光机200的电压满足国标GB4943安全特低电压的电路标准，该标准指出：一个电路内或几个互连的安全特低电压电路中，在正常工作条件及单一故障条件下，其任何两个导体之间和任何之间的电压不得超过42.4V交流峰值或60V直流值。因此本实施例中投影光机200的电压符合国标中的III类设备要求。另外，III类设备安装时不要求安全接地，因此可以在很大程度上降低投影光机200的安装成本。
成像模块203用于将光源模块202发出的光投射、聚焦到屏幕上进行成像，成像模块203可以由透镜、遮光组件及镜筒组成，即其主要用于对实物进行反射和成像。成像模块203可以与电源模块100连接而获得电源，即其可以通过与恒压输出端口102连接获得供电，另外，成像模块203可以通过与主板模块201连接获得图像，在光源模块202的作用下实现对图像的成像。另外，成像模块203可以设置在光源模块202的出光口处，光源模块202发出的光线经过成像模块203的变焦或放大等光学处理之后投射到光屏或墙面等成像面上。
请参阅图3，电源模块100包括恒压输出端口102、恒流输出端口103、电源输入端101以及电源转换电路110，恒压输出端口102与主板模块201连接，用于为所述主板模块201供电，恒流输出端口103与光源模块202连接，用于为所述光源模块202供电。本实施例中电源输入端101、恒压输出端口102和恒流输出端口103口均与所述电源转换电路110连接，所述电源输入端101用于与外部电源连接，所述电源转换电路110用于将电源输入端101输入的电源转换成投影光机200的工作电压。作为一种实施方式，电源转换电路110为直流/直流电源转换模块，用于将电源输入端101输入的直流电转换成两部分直流电，这两部 分直流电分别是恒压12V的直流电和恒流28V到45V的直流电。恒压12V的直流电用于为主板模块201提供工作电源，而恒流28V到45V的直流点用于为光源模块202提供工作电源。因此电源转换电路110的主要作用是将外部电源输入的电源转换成恒压信号和恒流信号，从而方便为投影光机200供电。
具体地，如图4所示，电源转换电路110可以包括变压器、恒流电路和恒压电路，该变压器包括初级线圈和次级线圈，初级线圈与电源输入端101连接，次级线圈包括至少两个接头，其中，该至少两个接头包括第一接头和第二接头，第一接头与恒流电路的输入端连接，恒流电路具有多个恒流输出端口103，电源输入端101输入的220V交流电经过变压器的降压之后，第一接头将降压后的电压输入恒流电流，经过恒流电路的恒流处理之后，得到恒流信号，然后由每个恒流输出端口103输入给每个投影光机200的光源模块202。其中，恒流电路可以是大功率恒流芯片，所述大功率恒流芯片可以包括电压源、集成运算放大器、电流采样电路和电阻，其主要用于将电源输入端101输入的交流电转换为恒定的电流，并将其通过接线端子传输至投影光机200，所述接线端子用于将恒流输出和恒压输出进行一一组合，例如，将恒压输出里面的恒压输出1和恒流输出里的恒流输出1组合在一起用于为投影光机200供电。
第二接头与恒压电路的输入端连接，恒压电路具有多个恒压输出端口102，电源输入端101输入的220V交流电经过变压器的降压之后，第二接头将降压后电压输入恒压电流，经过恒压电路的恒压处理之后，得到恒压信号，然后由每个恒压输出端口输入给每个投影光机200的主板模块201。其中，恒压电路可以是大功率的恒压芯片，恒压芯片原理和恒流芯片的基本原理相同，不同的是恒流芯片输出的是恒定的电流而恒压芯片输出的则是恒定的电压，同理，可以将所述恒定的电压通过接线端子传输至投影光机200为主板模块201供电。
电源模块100可以包括多组独立恒压输出和多组独立恒流输出，以图4为例，电源模块100包括9组独立恒压输出和9组恒流输出，每组都独立工作，且每组工作互不影响，如此，当某一组失效时其他组不会受到影响，换句话说， 某一组失效其他组仍然可以正常工作，恒压信号和恒流信号可以同时给每个单元供电。
具体地，恒流信号通过电源模块100的恒流输出端口103输出到投影光机200，电源转换电路110将输入电源转换成为9个恒压信号和9个恒流信号，因此，本实施例中电源模块100可以包括9个恒压输出端口102和9个恒流输出端口103，这些恒压输出端口102和恒流输出端口103可以交叉安装于电源模块100，也可以将所有恒压输出端口102安装在一起而将所有恒流输出端口103安装在一起，但是因为投影光机200的主板模块201需要的是恒压信号而光源模块202需要的是恒流信号，因此每个投影光机200都需要恒压信号和恒流信号，因此恒压输出端口102和恒流输出端口103可以交叉安装于电源模块100。
根据图4所示，恒流信号可以分为恒流输出1，恒流输出2，恒流输出3，恒流输出4，恒流输出5，恒流输出6，恒流输出7，恒流输出8，恒流输出9。恒压信号可以分为恒压输出1，恒压输出2，恒压输出3，恒压输出4，恒压输出5，恒压输出6，恒压输出7，恒压输出8，恒压输出9。本实施例中一个单元包括一个投影光机200，恒流输出1用于为单元1的光源模块202供电而恒压输出1用于为单元1的主板模块201供电；恒流输出2用于为单元2的光源模块202供电而恒压输出2用于为单元2的主板模块201供电；恒流输出3用于为单元3的光源模块202供电而恒压输出3用于为单元3的主板模块201供电；恒流输出4用于为单元4的光源模块202供电而恒压输出4用于为单元4的主板模块201供电；恒流输出5用于为单元5的光源模块202供电而恒压输出5用于为单元5的主板模块201供电；恒流输出6用于为单元6的光源模块202供电而恒压输出6用于为单元6的主板模块201供电；恒流输出7用于为单元7的光源模块202供电而恒压输出7用于为单元7的主板模块201供电；恒流输出8用于为单元8的光源模块202供电而恒压输出8用于为单元8的主板模块201供电；恒流输出9用于为单元9的光源模块202供电而恒压输出9用于为单元9的主板模块201供电。
需要说明的是，上述的恒流输出1，恒流输出2，恒流输出3，恒流输出4， 恒流输出5，恒流输出6，恒流输出7，恒流输出8，恒流输出9和恒压输出1，恒压输出2，恒压输出3，恒压输出4，恒压输出5，恒压输出6，恒压输出7，恒压输出8，恒压输出9分别与电源模块100的多个恒压输出端口102和恒流输出端口103一一对应，具体如何对应这里就不进行详细描述。
当电源转换电路110将电源转换成恒压信号和恒流信号后，所述恒压信号通过每个所述恒压输出端口102传输至该恒压输出端口102连接的主板模块201，以及将所述恒流信号通过每个所述恒流输出端口103传输至该恒流输出端口103连接的光源模块202。
通过上述分析可以获取到供电系统开机逻辑图，如图5所示，所述供电系统的开机逻辑包括步骤S501至S504。从图5可以看出供电系统进行工作首先需要将电源开机，将电源开机以后电源模块100才可以为其他模块进行供电，将电源开机后电源模块100的电源转换电路110将输入的电源转换成恒压信号和恒流信号，并将所述恒压信号和恒流信号输出到投影光机200上，投影光机200在接收所述恒压信号和所述恒流信号之前处于待机状态，而接收到所述恒压信号和所述恒流信号之后投影光机200可以自动打开可以通过开关进行打开，当投影光机200开机后，供电系统开始正常运行。需要说明的是，供电系统在关机时没有时序要求，可以先将投影光机200关闭后再关电源模块100，也可以直接将电源模块100关闭。
本申请实施例通过将供电系统的电源模块和投影光机分开而实现对系统的供电，通过将电源模块和投影光机分离可以提高供电系统的安全性能，人体可以直接接触投影光机而不被伤害。另外，本申请实施例中电源模块采用了电源集成技术，通过电源集成可以集中控制多个投影光机，这也可以使得单个投影光机失效的因素减少，在很大程度上降低多个投影光机拼接在一起的风险点，进而可以提高整个供电系统的可靠性。从上述介绍可以知道电源模块可以包含多个电压输出端口和多个电流输出端口，这些输出端口用于为多个投影光机提供电能，在有限的资源下本实施例可以完成整个供电系统的一个协同 控制，极大提高电源的利用率。综上所述，本申请实施例通过电源集中控制，将电源模块与投影光机分离，可以在一定程度上减少投影光机的体积，在有限的空间内也可以使用本供电系统，因此在提高模块利用率的同时本申请实施例可以提升供电系统安装环境的适应性。
请参阅图6，为了使上述系统更加完善以及方便将所有独立的单元拼接在一起，本实施例引入了控制器400，控制器400主要用于进行图像信号的处理以及完成多个单元拼接功能，现有技术中控制器400也是由220V供电，同样也会带来安全性不高、电源利用率低以及资源浪费等问题，发明人考虑到控制器400的主要作用是信号处理，一般只需要12V供电就可以了，因此本实施例同样可以舍去控制器400中的220V电源供电。和图3类似本实施例中同样以电源模块100为一个投影光机200供电为例，控制器400与主板模块201连接，控制器400与电源模块100连接。其中，控制器400与主板模块201连接，在控制器与主板模块之间能够实现数据的交互，作为一种实施方式，控制器400包括第一数据端口，同理，主板模块201包括第二数据端口，则第一数据端口和第二数据端口均可以是一个I/O引脚，则控制器400的第一数据端口与主板模块201的第二数据端口连接，以使控制器400与主板模块201传输数据，例如，控制器400向主板模块201发送控制指令，以使主板模块201执行该控制指令对应的操作，例如，控制器400向主板模块201发送亮度调节指令，以使主板模块201根据该亮度调节指令调整光源模块的发光亮度。
控制器400与电源模块100连接，该控制器400能够从电源模块100处取电，以获得工作电压，作为一种实施方式，可以是控制器400包括一电源端口，电源模块100包括电源输出端口，则电源模块的电源输出端口与控制器的电源端口连接，则控制器能够通过该电源端口从电源模块出取电。
控制器400可以包括第二电压输出端口205，控制器400可以通过所述第二电压输出端口205为其他装置供电。另外，控制器400既与主板模块201连接，又与电源模块100连接，图6中控制器通过与恒压输出端口102连接获得供电。
具体，如图7所示，供电系统可以包括多个控制器400，每个控制器400可以与一个单元的主板模块201的控制端连接，多个控制器400放入电源端均与电源模块100连接，从图7可知一个单元可以包括一个控制器400，这些控制器400与单元一一对应，分别命名为控制器1，控制器2，控制器3，控制器4，控制器5，控制器6，控制器7，控制器8，控制器9。
电源模块100可以包括多组独立恒压输出和多组独立恒流输出，以图7为例，电源模块100包括9组独立恒压输出和9组独立恒流输出，即电源模块100包括多个恒压输出端口102，这些恒压输出端口可以分别为恒压输出端口1，恒压输出端口2，恒压输出端口3，恒压输出端口4，恒压输出端口5，恒压输出端口6，恒压输出端口7，恒压输出端口8，恒压输出端口9。控制器1通过与恒压输出端口1连接得到供电，控制器2通过与恒压输出端口2连接得到供电，控制器3通过与恒压输出端口3连接得到供电，控制器4通过与恒压输出端口4连接得到供电，控制器5通过与恒压输出端口5连接得到供电，控制器6通过与恒压输出端口6连接得到供电，控制器7通过与恒压输出端口7连接得到供电，控制器8通过与恒压输出端口8连接得到供电，控制器9通过与恒压输出端口9连接得到供电。综上所述，控制器400可以直接利用恒压输出端口102从电源模块100获得电源。
请参阅图8，控制器400也可以通过与第一电压输出端口204连接获得供电，通过上述介绍可以知道投影光机200可以包括第一电压输出端口204，即本实施例中电源模块100可以通过第一电压输出端口204与控制器400连接，所述第一电压输出端口204用于为所述控制器400供电，因此，控制器400也可以通过与投影光机200连接而获得电源。具体如图9所示，控制器1可以通过与单元1的第一电压输出端口204连接获得电源，控制器2可以通过与单元2的第一电压输出端口204连接获得电源，控制器3可以通过与单元3的第一电压输出端口204连接获得电源，控制器4可以通过与单元4的第一电压输出端口204连接获得电源，控制器5可以通过与单元5的第一电压输出端口204连接获得电源，控制器 6可以通过与单元6的第一电压输出端口204连接获得电源，控制器7可以通过与单元7的第一电压输出端口204连接获得电源，控制器8可以通过与单元8的第一电压输出端口204连接获得电源，控制器9可以通过与单元9的第一电压输出端口204连接获得电源。
控制器400通过与恒压输出端口102连接或者通过与第一电压输出端口204连接后获得电源，控制器400获得供电后对投影光机200传输的图像信号进行等分处理、融合处理以及拼接处理等，所述等分处理主要是将投影光机200传输的图像进行等分，等分后利用融合处理将等分后的图像信息进行融合，接着对融合处理后的图像进行拼接处理，即将等分并融合的图像按照设定的顺序进行投影实现拼接。
本申请实施例通过加入控制器而使得整个供电系统更加完整，控制器不仅可以用来对图像信号进行处理，而且还可以用来将单个独立的互不干扰的单元连接在一起，进而实现多个单元的拼接工作。另外，因为本申请实施例中控制器的供电也是与现有技术有显著的区别，本申请实施例中控制器的供电一般只需要12V就可以了，如此，在很大程度上能够提高电源的利用率，减少电源的浪费，可以降低整个供电系统的成本。
为了使得供电系统具有防尘和美观的效果需要对每个单元箱体加上后盖，但是如果加上箱体后会供电系统的散热就会收到影响，因此本实施例中对每个单元加上散热装置500，请参阅图10，所述散热装置500与所述电源模块100连接，其主要用于为投影光机200散热。散热装置500可以是一个散热风扇，也可以是多个散热风扇，如果散热装置500由多个散热风扇组成，那么这些散热风扇可以是串联在一起也可以是并联在一起，具体是串联还是并联这里不进行明确限制。散热装置500用于将投影光机200产生的热量吹拂到周围空气中，从而达到降温的效果。

电源模块100可以具备多组独立恒压输出和多组独立恒流输出，具体有多少组恒流输出和恒压输出这里不做限制，本实施例以9组独立恒压输出和9组独立恒流输出为例，如图11所示。电源模块100包括多个恒压输出端口102，这些恒压输出端口分别为恒压输出端口1，恒压输出端口2，恒压输出端口3，恒压输出端口4，恒压输出端口5，恒压输出端口6，恒压输出端口7，恒压输出端口8，恒压输出端口9。散热装置1通过与恒压输出端口1连接得到供电，散热装置2通过与恒压输出端口2连接得到供电，散热装置3通过与恒压输出端口3连接得到供电，散热装置4通过与恒压输出端口4连接得到供电，散热装置5通过与恒压输出端口5连接得到供电，散热装置6通过与恒压输出端口6连接得到供电，散热装置7通过与恒压输出端口7连接得到供电，散热装置8通过与恒压输出端口8连接得到供电，散热装置9通过与恒压输出端口9连接得到供电。综上所述，散热装置500可以直接利用恒压输出端口102从电源模块100获得电源。
请参阅图12，散热装置500也可以通过与单元的投影光机200连接而获得电源，通过上述介绍可以知道投影光机200还包括第一电压输出端口204，即所述电源模块100可以通过所述第一电压输出端口204与所述散热装置500连接，所述第一电压输出端口204用于为所述散热装置500供电。具体如图13所示，散热装置1可以通过与单元1的第一电压输出端口204连接获得电源，散热装置2可以通过与单元2的第一电压输出端口204连接获得电源，散热装置3可以通过与单元3的第一电压输出端口204连接获得电源，散热装置4可以通过与单元4的第一电压输出端口204连接获得电源，散热装置5可以通过与单元5的第一电压输出端口204连接获得电源，散热装置6可以通过与单元6的第一电压输出端口204连接获得电源，散热装置7可以通过与单元7的第一电压输出端口204连接获得电源，散热装置8可以通过与单元8的第一电压输出端口204连接获得电 源，散热装置9可以通过与单元9的第一电压输出端口204连接获得电源。
