背景技术
部分家庭中通常采用可控硅调光器对照明产品进行调光。而随着无线通信技术和互联网技术的高速发展，无线通信技术和互联网技术也逐渐应用到照明产品中，因此，目前也可以对照明产品进行无线开关以及调光调色。并且近年来随着技术的进步，有的照明产品已经可以实现既能够通过可控硅调光器进行调光，也能够采用无线控制装置进行调光调色。但是，在实际应用中，发现这样的照明产品会存在问题。
具体的，用户采用无线控制装置对照明产品进行调光，并且将亮度调至中低端之后，此时如果再使用传统的可控硅调光器进行调光，可控硅调光器的调光范围会变得很窄，无法在整个调光区域内对整灯进行亮度调节。即此时的可控硅调光器无法将照明产品调成较亮的亮度。特别是在家庭中有年轻人和年长者的场合中，以上两个问题时有发生。年长者习惯使用传统的可控硅调光器进行调光，年轻人则偏爱使用无线控制的方式智能调光。
综上所述，如何有效地进行照明产品的调光，并且能够避免上述问题的发生，是目前本领域技术人员急需解决的技术问题。

一种照明设备，包括上述任一项所述的照明控制系统。
申请人经过分析之后发现，传统的照明产品中，当用户使用可控硅调光器进行调光并且将亮度调至中低端之后，再用无线控制装置调光，无线控制装置显示出的亮度值不能真实地反映出当前的实际亮度。出现这种情况的原因是传统的无线控制装置会默认前级的电压是在正常范围内，如果可控硅调光器进行了调光并且将亮度调至中低端之后，此时整流电路的输出电压就会远低于正常范围，使得传统的无线控制装置显示出的亮度值远高于实际的亮度值。因此，本申请的方案中，设置了用于检测流经照明负载的电流的电流检测电路40，控制器60可以将电流检测电路40检测出的电流值无线传输至无线控制装置70，无线控制装置70则可以显示接收的电流值，而由于流经照明负载的电流能够直接准确地反映出照明负载的亮度情况，因此本申请的方案的无线控制装置70能够真实地反映出照明负载的当前的实际亮度情况。
并且申请人发现，传统的照明产品中用户采用传统的无线控制装置对照明产品进行调光并且将亮度调至中低端之后，此时如果再使用传统的可控硅调光器进行调光，可控硅调光器的调光范围会变得很窄，无法在整个调光区域内对整灯进行亮度调节。这是因为传统的无线控制装置对电路中 的相关调光电路进行了控制，使得施加到负载的功率受到了限制。因此，本申请的方案中设置了可控硅调光检测电路50，在可控硅调光检测电路50确定出可控硅调光器10被执行了第一预设操作时，说明用户此时对可控硅调光器10进行了约定的第一预设操作，此时控制器60便会控制调光恒流电路30恢复为默认状态，从而解除无线控制装置70对调光恒流电路30的限制。因此，本申请的方案中，无线控制装置70对照明产品进行调光并且将亮度调至中低端之后，再用可控硅调光器10进行调光仍然可以在整个调光区域内对整灯进行亮度调节。

具体实施方式
本申请的核心是提供一种照明控制系统，使用可控硅调光器进行调光并且将亮度调至中低端之后，再使用无线控制装置70调光时，无线控制装置70仍然能够真实地反映出照明负载的当前的实际亮度情况。同时，无线控制装置70对照明产品进行调光并且将亮度调至中低端之后，可控硅调光器10仍然可以在整个调光区域内对整灯进行亮度调节。
为了使本技术领域的人员更好地理解本申请方案，下面结合附图和具体实施方式对本申请作进一步的详细说明。显然，所描述的实施例仅仅是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，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，都属于本申请保护的范围。
请参考图1，图1为本申请中的一种照明控制系统的结构示意图，该照明控制系统可以包括：
设置在照明装置的供电线路上，用于调整照明负载的亮度的可控硅调光器10。
无线控制装置70；
分别与无线控制装置70以及可控硅调光器10连接的照明装置；
照明装置包括：
与可控硅调光器10连接，用于接收交流输入的整流电路20；
与整流电路20以及照明负载连接的调光恒流电路30；
分别与可控硅调光检测电路50以及调光恒流电路30连接的控制器60，用于在接收到无线控制装置70发送的亮度控制信号时，根据亮度控制信号控制调光恒流电路30以对照明负载的亮度进行调整；并用于在可控硅调光检测电路50确定出可控硅调光器10被执行了第一预设操作时，控制调光恒流电路30恢复为默认状态以解除无线控制装置70对调光恒流电路30的限制；
可控硅调光检测电路50。
具体的，可控硅调光器10可以对电压的相位角进行调节，也即，可以对导通角度进行控制。可以理解的是，导通角度越大，整流电路20输出端的电压越高。
可控硅调光器10通常会设置在火线上，特别是部分发达国家的家庭中通常都会安装有可控硅调光器10。
整流电路20与可控硅调光器10连接，整流电路20可以将接收的交流输入进行整流，具体的电路构成可以根据实际情况进行设定和调整，例如图2的实施方式中的整流电路20由4个二极管构成，电路结构简单可靠性高，且均是无源器件，无需进行控制。
调光恒流电路30可以接收控制器60的电信号，从而根据该信号携带的信息对照明负载的亮度进行控制。调光恒流电路30可以采用PWM调光或者模拟调光的方式，并且，在实际应用中，调光恒流电路30通常可以采用模拟调光的方式进行调光，有利于避免照明负载在调光过程中出现闪烁的情况。
进一步地，在本申请的一种具体实施方式中，还可以包括：与调光恒流电路30并联，用于提供维持电流的泄放电路。
该种实施方式中，考虑到本申请的方案可以采用可控硅调光器10进行 调光，并且用户可能会通过可控硅调光器10将照明负载的亮度调得很低，如果此时回路中的电流低于可控硅调光器10的最低工作电流，照明负载便会出现闪烁的情况。因此，本申请的方案中还设置了与调光恒流电路30并联，用于提供维持电流的泄放电路，可以为可控硅调光器10提供维持电流，有利于保障可控硅调光器10在调光过程中不会造成照明负载出现闪烁情况。
泄放电路的具体电路构成可以根据实际情况进行设定和调整，可以采用有源泄放电路，也可以采用无源泄放电路。图2的实施方式中便示出了一种具体场合中的泄放电路的结构示意图。
控制器60在接收到无线控制装置70发送的亮度控制信号时，便可以根据亮度控制信号控制调光恒流电路30，从而对照明负载的亮度进行调整。例如图2的实施方式中，控制器60可以发送PWM信号至调光恒流电路30中的芯片U2的DIM引脚，芯片U2根据该引脚接收的信号的不同，对照明负载相应地进行控制。当然，图2中并未示出控制器60以及无线控制装置70。
此外，实际应用中，通常可以将整流电路20输出的电压经过降压之后为控制器60供电，例如图2的实施方式中，在整流电路20的后端设置了LC滤波电路，LC滤波电路之后可以接降压电路，例如将电压等级降低至5V以及3.3V，从而为电路中的控制器60以及其他有源器件供电。
进一步的，可参阅图3，在本申请的一种具体实施方式中，还可以包括：
用于检测流经照明负载的电流的电流检测电路40；
控制器60还可以用于：将电流检测电路40检测出的电流值无线传输至无线控制装置70；
无线控制装置70还用于：显示接收的电流值。
在实际应用中，申请人还发现传统的照明产品在使用过程中，当用户使用传统的可控硅调光器进行调光，并且将亮度调至中低端时，此时再使用传统的无线控制装置进行调光，会出现照明产品的亮度远远低于预期的情况，即，传统的无线控制装置此时显示出的亮度值不能真实地反映出当 前的实际亮度。
并且，申请人经过分析之后发现，传统的照明产品中，当用户使用可控硅调光器进行调光并且将亮度调至中低端之后，再用无线控制装置调光，无线控制装置显示出的亮度值不能真实地反映出当前的实际亮度。出现这种情况的原因是传统的无线控制装置会默认前级的电压是在正常范围内，如果可控硅调光器进行了调光并且将亮度调至中低端之后，此时整流电路的输出电压就会远低于正常范围，使得传统的无线控制装置显示出的亮度值远高于实际的亮度值。
因此，本申请的方案中，设置了用于检测流经照明负载的电流的电流检测电路40，控制器60可以将电流检测电路40检测出的电流值无线传输至无线控制装置70，无线控制装置70则可以显示接收的电流值，而由于流经照明负载的电流能够直接准确地反映出照明负载的亮度情况，因此本申请的方案的无线控制装置70能够真实地反映出照明负载的当前的实际亮度情况。
此外，在实际应用中，针对具体的照明负载，流经该照明负载的电流值与该照明负载的亮度之间的对应关系是可以预先确定的，因此，便于用户对当前亮度情况进行了解，无线控制装置70除了显示电流值之外，还可以确定出对应于当前显示的电流值的亮度值并显示给用户，使得用户更加方便且直观地获知当前的照明负载的亮度情况。
本申请的无线控制装置70可以是专门设置的无线控制装置70，而在部分实施方式中，为了降低成本，无线控制装置70可以为用户常常会携带的手机或平板电脑，在手机或平板电脑上安装相关APP使得手机或平板电脑能够实现本申请的无线控制装置70的功能，移动设备也便于携带。
并且需要说明的是，当采用手机或平板电脑作为无线控制装置70时，通常可以采用蓝牙的通信方式。此外，在一些实施方式中，用户可能希望使用wifi等无线通信方式，则可以使用手机或平板电脑以及云端设备来构成本申请的无线控制装置70。例如手机通过wifi与云端进行通信连接，云端再通过wifi与照明装置连接，即云端通过wifi与照明装置中的控制器60通信连接。
例如，手机上显示当前将调光恒流电路30调到了70％，且显示当前的照明负载的亮度为350mcd，电流值大小为A。用户通过点击手机上的相关软件的按键，将调光恒流电路30调到了80％，此时手机显示当前的照明负载的亮度达到了420mcd，电流值大小为B。
并且需要说明的是，调光恒流电路30以及可控硅调光器10均可以调整照明负载的亮度，因此，通过无线控制装置70进行亮度调整时，可能会无法调到最亮的程度。例如，用户对手机进行操作，将调光恒流电路30调到了100％，即手机会将把调光恒流电路30调至100％这个信息发送至控制器60，控制器60通过调光恒流电路30调光完成之后，手机上显示亮度当前的实际亮度是550mcd，并不能达到600mcd这个的最亮的亮度。则可以说明前级的可控硅调光器10对电压进行了限制，如果用户需要让照明负载达到600mcd这一亮度，则需要手动对可控硅调光器10进行操作。但是，可以看出，用户操作手机将调光恒流电路30调到了100％之后，本申请的方案中，通过流经照明负载的电流值，使得本申请的方案可以在手机上真实准确地反映出当前的亮度情况。例如前述例子中，将调光恒流电路30调到了100％之后，手机上真实地显示出当前的实际亮度是550mcd，而不会错误地显示600mcd。
此外，该例子中描述的将调光恒流电路30调到70％、80％以及100％等数值，指的是调光恒流电路30对照明负载的调光控制程度。在其他条件相同的前提下，该数值越大，说明调光恒流电路30控制照明负载越亮。当然，将调光恒流电路30开到最大，即，将调光恒流电路30调到100％时，在其他条件相同的前提下，照明负载亮度最大。
在可控硅调光检测电路50确定出可控硅调光器10被执行了第一预设操作时，本申请的控制器60会控制调光恒流电路30恢复为默认状态以解除无线控制装置70对调光恒流电路30的限制。
可控硅调光检测电路50的具体形式可以根据实际需要进行设定和调整，通常可以是电压检测电路50。本申请的图3中，可控硅调光检测电路50便是选取为电压检测电路50。
具体的，在本申请的一种具体实施方式中，可控硅调光检测电路50 为与整流电路20连接，用于检测整流电路20的输出电压的电压检测电路50。该种实施方式中，在电压检测电路50检测出的电压的变化符合预设的第一轨迹时，电压检测电路50确定出可控硅调光器10被执行了第一预设操作；
电压检测电路50检测出的电压的变化符合预设的第一轨迹，说明用户进行了一次约定的操作。并且需要说明的是，电压检测电路50检测出的电压的变化，可以包括电压幅值的变化和/或相位的变化。以幅值为例，例如在一种具体场合中，用户将可控硅调光器10调到最大然后再调至最小，在这一过程中，电压检测电路50检测出的电压值便会上升至最大然后又降低至最小，控制器60便可以确定电压检测电路50检测出的电压的变化符合预设的第一轨迹。并且可以理解的是，在实际应用中，考虑到检测误差，电压的变化并非需要与预设的第一轨迹完全重合才算是符合预设的第一轨迹，例如，该例子中约定的操作是用户将可控硅调光器10调到最大然后再调至最小，则只要电压检测电路50检测出的电压值高于预设的阈值上限，并且在预设的第一时长之内，电压检测电路50检测出的电压值降低，且低于了预设阈值下限，则控制器60便可以确定电压值的变化符合了预设的第一轨迹。当然，其他场合中，还可以有更为复杂、准确地判定电压的变化是否符合预设的第一轨迹方式，根据实际需要进行设定和选取即可，并不影响本申请的实施。
当然，除了选取电压检测电路50作为可控硅调光检测电路50之外，可控硅调光检测电路50也可以采用其他的具体形式，只要能够检测出用户对可控硅调光器10执行了第一预设操作即可。
可控硅调光检测电路50确定出可控硅调光器10被执行了第一预设操作之后，说明此时用户需要用可控硅调光器10进行调光。因此为了使得可控硅调光器10能够在整个范围内进行调光，本申请的方案中，控制器60会控制调光恒流电路30恢复为默认状态，从而解除无线控制装置70对调光恒流电路30的限制。
例如，家庭中的老人在用可控硅调光器10之前，年轻人先用无线控制装置70，例如手机，将调光恒流电路30调到了20％，如果不解除无线控 制装置70对调光恒流电路30的限制，则即使将可控硅调光器10调到了最大，此时照明负载的亮度依旧会偏低。而控制器60控制调光恒流电路30恢复为默认状态之后，例如控制调光恒流电路30恢复为100％，则可控硅调光器10便可以在整个亮度范围内进行调整。
调光恒流电路30的默认状态指的是调光恒流电路30对照明负载的亮度控制程度高于预设阈值的状态，通常情况下，在默认状态下，调光恒流电路30的调光为100％，即预设阈值通常为100％。当然，在其他场合中，默认状态也可以不是100％而是根据实际需要选取为其他的数值例如为90％。但是需要强调的是，该数值不能太低，避免用户通过可控硅调光器10无法将照明负载调地较亮。
在本申请的一种具体实施方式中，还可以包括：
分别与照明负载以及控制器60连接的色温调整电路；
控制器60还用于：在接收到无线控制装置70发送的色温控制信号时，根据色温控制信号控制色温调整电路以对照明负载的色温进行调整。
除了调光之外，本申请的照明控制系统中还可以设置有色温调整电路，控制器60可以在接收到无线控制装置70发送的色温控制信号时，根据色温控制信号中携带的信息，控制色温调整电路，从而对照明负载的色温进行调整。可以理解的是，由于该种实施方式中需要对色温进行调整，因此照明负载应当是至少包括两种色温的照明负载。
照明负载通常可以是LED灯，并且可以由单个LED灯构成本申请的照明负载，也可以是多个LED灯串联/并联的组合构成本申请的照明负载，均不影响本申请的实施。图2的实施方式中便是多个LED灯串联构成的LED负载。
此外，为了使得用户可以直观准确地获知当前的色温情况，控制器60还可以用于：将照明负载的色温发送至无线控制装置70以使无线控制装置70显示照明负载的色温。
前述实施方式中，用户可以用无线控制的方式进行色温调整，在本申请的另一种实施方式中，用户还可以用可控硅调光器10对色温进行调整。具体的，控制器60还用于：
在可控硅调光检测电路50确定出可控硅调光器10被执行了第二预设操作时，按照预设的色温控制策略控制色温调整电路以对照明负载的色温进行调整。
仍以可控硅调光检测电路50选取为电压检测电路50为例进行说明。即该种实施方式中，在电压检测电路50检测出的电压的变化符合预设的第二轨迹时，电压检测电路50确定出可控硅调光器10被执行了第二预设操作。
例如，用户需要用可控硅调光器10对色温进行调整时，约定的操作是将可控硅调光器10调到最大然后再调至最小，且重复两次。控制器60在确定出电压检测电路50检测出的电压的变化符合预设的第二轨迹时，可以确定用户此时对可控硅调光器10进行了约定的色温调整的操作，即第二预设操作。则控制器60会按照预设的色温控制策略控制色温调整电路。预设的色温控制策略也可以根据需要进行设定和调整，例如预设了1级，2级，3级，4级一共4个不同等级的色温，当用户执行一次约定的色温调整的操作时，控制器60便控制色温调整电路将照明负载的色温提高一级。当然，4级时则调回1级。
在本申请的一种具体实施方式中，控制器60在根据亮度控制信号控制调光恒流电路30以对照明负载的亮度进行调整时，按照逐级调节的方式进行调节，使得照明负载的亮度达到亮度控制信号中携带的亮度值。
在实际应用中，便于用户的使用，无线控制装置70可以支持用户多种输入方式。例如，用户可以在0至100％这个范围内对调光恒流电路30进行控制，从而实现调光，例如用户需要将调光恒流电路30调至40％，则无线控制装置70此时只需要将这一信息发送至控制器60，进而对调光恒流电路30进行控制，使得调光恒流电路30达到40％即可。
但是，用户有时会直接输入亮度值，或者直接输入一个需要的亮度在最大亮度中的占比，而本申请的照明负载的亮度受到调光恒流电路30以及可控硅调光器10的控制。一种解决方式是控制器60需要获得当前的可控硅调光器10对电压的限制情况，进而确定出应该如何调整调光恒流电路30，使得照明负载的亮度达到用户需要的亮度值，但是这样的方式较为复 杂。因此，该种实施方式中，控制器60会按照逐级调节的方式进行调节，使得照明负载的亮度达到亮度控制信号中携带的亮度值。
具体的，用户输入希望达到的亮度值之后，该亮度值对应的流经照明负载的目标电流值是可以确定的，此时只需要逐级调整，即控制器60每次给调光恒流电路30一个较小的变化步长，然后判断流经负载的电流值是否达到了目标电流值。经过多次调整之后，可以使得流经照明负载的电流值达到目标电流值。
申请人经过分析之后发现，传统的照明产品中，当用户使用可控硅调光器进行调光并且将亮度调至中低端之后，再用无线控制装置调光，无线控制装置显示出的亮度值不能真实地反映出当前的实际亮度。出现这种情况的原因是传统的无线控制装置会默认前级的电压是在正常范围内，如果可控硅调光器进行了调光并且将亮度调至中低端之后，此时整流电路的输出电压就会远低于正常范围，使得传统的无线控制装置显示出的亮度值远高于实际的亮度值。因此，本申请的方案中，设置了用于检测流经照明负载的电流的电流检测电路40，控制器60可以将电流检测电路40检测出的电流值无线传输至无线控制装置70，无线控制装置70则可以显示接收的电流值，而由于流经照明负载的电流能够直接准确地反映出照明负载的亮度情况，因此本申请的方案的无线控制装置70能够真实地反映出照明负载的当前的实际亮度情况。
并且申请人发现，传统的照明产品中用户采用传统的无线控制装置对照明产品进行调光并且将亮度调至中低端之后，此时如果再使用传统的可控硅调光器进行调光，可控硅调光器的调光范围会变得很窄，无法在整个调光区域内对整灯进行亮度调节。这是因为传统的无线控制装置对电路中的相关调光电路进行了控制，使得施加到负载的功率受到了限制。因此，本申请的方案中设置了可控硅调光检测电路50，在可控硅调光检测电路50确定出可控硅调光器10被执行了第一预设操作时，说明用户此时对可控硅调光器10进行了约定的第一预设操作，此时控制器60便会控制调光恒流电路30恢复为默认状态，从而解除无线控制装置70对调光恒流电路30 的限制。因此，本申请的方案中，无线控制装置70对照明产品进行调光并且将亮度调至中低端之后，再用可控硅调光器10进行调光仍然可以在整个调光区域内对整灯进行亮度调节。
相应于上面的照明控制系统的实施例，本申请实施例还提供了一种照明设备，可与上文相互对应参照，此处不再重复说明。
专业人员还可以进一步意识到，结合本文中所公开的实施例描述的各示例的单元及算法步骤，能够以电子硬件、计算机软件或者二者的结合来实现，为了清楚地说明硬件和软件的可互换性，在上述说明中已经按照功能一般性地描述了各示例的组成及步骤。这些功能究竟以硬件还是软件方式来执行，取决于技术方案的特定应用和设计约束条件。专业技术人员可以对每个特定的应用来使用不同方法来实现所描述的功能，但是这种实现不应认为超出本申请的范围。
本文中应用了具体个例对本申请的原理及实施方式进行了阐述，以上实施例的说明只是用于帮助理解本申请的技术方案及其核心思想。应当指出，对于本技术领域的普通技术人员来说，在不脱离本申请原理的前提下，还可以对本申请进行若干改进和修饰，这些改进和修饰也落入本申请权利要求的保护范围。
