为了更清楚地说明本发明实施例中的技术方案，下面将对现有技术和实施例中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本发明的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据这些附图获得其他的附图。

具体实施方式
本发明的核心是提供一种LED的控制电路及照明系统，通过控制开关和处理器之间的配合即可实现对LED组合的亮度和色温的模式的切换，且处理器的兼容性较高，无需调光器对灯光的亮度进行控制，减小了成本。
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。基于本发明中的实施例，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，都属于本发明保护的范围。
请参照图1，图1为本发明提供的一种LED的控制电路的结构示意图，该控制电路包括：
第一端与电源1连接，第二端与处理器3连接的控制开关2，用于基于用户的指令相应地控制电源1与处理器3之间的电路导通或关断；
多个输出端分别一一对应与多个LED(Light-Emitting Diode，发光二极管)组合4连接的处理器3，用于在控制开关2于预设时间内进行了预设次数的动作后控制各个LED组合4于控制开关2动作前的亮度和色温模式切换至下一亮度和色温模式；
各个LED组合4的色温各不相同，且各个亮度和色温模式对应的亮度和/或色温各不相同。
申请人考虑到现有技术中的灯具在调节亮度和色温时，通常由拨码开关调节色温，调光器调节亮度，但是调光器的成本较高，且不能适用于所有的灯，因此，现有技术中的对灯光的色温和亮度的调节的方式无法满足用户的多种需要。
为解决上述技术问题，本申请中LED的控制电路设有控制开关2和处理器3，控制开关2设置于电源1和处理器3之间，控制开关2于预设时间内进行了预设次数的动作时，处理器3将亮度和色温模式进行切换，具体地，处理器3在切换亮度和色温模式时，通过将与控制开关2动作前的亮度和色温模式对应的LED组合4的亮度按照下一亮度和色温模式对应的亮度进行改变，即只改变LED组合4的亮度，但不对其色温进行改变，实现亮度和色温模式的切换；或将与控制开关2动作前的亮度和色温模式对应的LED组合4熄灭，并将下一亮度和色温模式对应的LED组合4按照相应的亮度点亮，即LED组合4的亮度和色温同时改变，实现亮度和色温模式的切换。
需要说明的是，LED组合4的数量为多个，且各个LED组合4的色温和亮度各不相同，各个亮度和色温模式对应的亮度和色温各不相同，每个LED组合4的色温和亮度可以对应一个亮度和色温模式，也可以多个LED组合4同时点亮时的亮度和色温对应一个亮度和色温模式，且各个LED组合4中各个LED的亮度可以由最大亮度，也即最高功率对应的亮度的1％至100％之 间调节，虽然各个LED组合4的色温的调节只能通过点亮或熄灭相应的LED组合4实现，但是，各个LED组合4的亮度的调节可以通过对其功率的调节来实现，从而能够以固定的LED组合4的数量，设置更多的亮度和色温模式，进一步满足用户的需求。
当然，由于本申请中各个LED组合4的色温和亮度各不相同，处理器3无需对LED组合4中各个LED的功率和颜色进行改变，从而实现对亮度和色温的调节，仅通过控制相应的LED组合4点亮或熄灭，即可实现对亮度和色温模式的改变。
其中，预设时间可以但不限定为200ms至900ms范围内的时间，预设次数可以为两次，例如控制开关2在200ms内动作两次，处理器3即对亮度和色温模式进行切换，即控制开关2每断开并在预设时间内重新导通一次，处理器3便对亮度和色温模式切换一次。
需要说明的是，本申请中处理器3在判断控制开关2是否于预设时间内进行了预设次数的动作前，存在LED组合4处于点亮的状态。
需要说明的是，本申请中的亮度和色温模式的顺序可以但不限定亮度和色温均呈递增的趋势或均呈递减的趋势，其中，每一个亮度和色温模式对应的亮度各不相同，但是，多个亮度和色温模式对应的色温可以相同。例如，第一亮度和色温模式和第二亮度和色温模式对应的色温相同，但是，第一亮度和色温模式对应的亮度高于第二亮度和色温模式对应的亮度，即可设定处于第一亮度和色温模式和处于第二亮度和色温模式时，处于点亮状态的LED组合4相同，但是，处于点亮状态的LED组合4于第一亮度和色温模式时的功率高于处于第二亮度和色温模式时的功率，即可实现第一亮度和色温模式和第二亮度和色温模式对应的色温相同，但是，第一亮度和色温模式对应的亮度高于第二亮度和色温模式对应的亮度，或下一亮度和色温模式的亮度高于或低于上一亮度和色温模式的亮度，但多个亮度和色温模式对应的色温相同。
例如，LED组合4包括第一LED组合和第二LED组合，第一LED组合41的最大亮度高于第二LED组合42的最大亮度，且第一LED组合41的色温高于第二LED的色温。控制开关2动作前的亮度和色温模式为第一LED组合的 色温，且亮度为第一LED组合的最大亮度的70％，控制开关2动作前的亮度和色温模式的下一亮度和色温模块为第一LED组合的色温，但是亮度为第一LED组合的最大亮度的50％，当将控制开关2动作前的亮度和色温模式切换至下一亮度和色温模块时，与第一LED组合连接的驱动处理器将第一LED组合的亮度由最大亮度的70％调至最大亮度的50％即可。
具体地，例如，第一LED组合以亮度为最大亮度的70％点亮且第二LED组合42熄灭时为第一亮度与色温模式；第一LED组合以亮度为最大亮度的50％点亮且第二LED组合熄灭时为第二亮度与色温模式；第一LED组合以亮度为最大亮度的50％点亮且第二LED组合以亮度为最大亮度的70％点亮时为第三亮度与色温模式；第一LED组合熄灭且第二LED组合以亮度为最大亮度的70％点亮时为第三亮度与色温模式；第一LED组合熄灭且第二LED组合以亮度为最大亮度的50％点亮时为第三亮度与色温模式。
其中，第一LED组合的色温可以但不仅限为4000K、5000K或5500K，根据实际应用要求而定，亮度为1500流明，可通过改变第一LED组合中LED的功率实现，满足需要办公写作业时对灯光的需求；第二LED组合的色温可以但不仅限为2700K、3000K或3200K，可根据实际应用要求而定，亮度为300流明，可通过改变第二LED组合中LED的功率实现，满足对睡前温馨暖光低亮度的需求，第一LED组合和第二LED组合共同点亮时，色温为3000K，亮度为800流明，可通过改变第一LED组合中LED的功率和第二LED组合中LED的功率实现，满足家庭起居正常生活时对灯光的需求。
此外，本申请中可直接利用现有技术中的控制开关作为控制开关2。
需要说明的是，本申请中的处理器3的兼容性较高，其所能够控制的灯的类型不受限制，能够进一步降低成本。
综上，本申请通过控制开关2和处理器3之间的配合即可实现对LED组合4的亮度和色温的模式的切换，且处理器3的兼容性较高，无需调光器对灯光的亮度进行控制，减小了成本。
在上述实施例的基础上：
作为一种优选的实施例，处理器3包括：
电源1输入端与控制开关2的第二端连接的存储处理器U2，用于存储控制开关2动作前的亮度和色温模式；
电源1输入端与控制开关2的第二端连接的控制处理器U1，用于在控制开关2于预设时间内进行了预设次数的动作后通过相应的信号输出端输出相应的控制信号，以将各个LED组合4于存储处理器U2存储的亮度和色温模式切换至下一亮度和色温模式；
信号输入端分别与控制处理器U1对应的信号输出端连接，输出端分别一一对应与多个LED组合4连接的多个驱动处理器，用于在接收到控制处理器U1发送的控制信号时，控制与自身连接的LED组合4按照与控制信号对应的亮度点亮，并在未接收到控制信号时控制与自身连接的LED组合4熄灭。
本实施例中，申请人考虑到处理器3在切换亮度和色温模式时，需要基于控制开关2动作前的亮度和色温模式切换至下一亮度和色温模式，因此，需要预先存储控制开关2动作前的亮度和色温模式，从而在控制开关2于预设时间内进行了预设次数的动作后控制控制开关2动作前的亮度和色温模式对应的LED组合4的亮度按照下一亮度和色温模式对应的亮度进行改变，即只改变LED组合4的亮度，但不对其色温进行改变，实现亮度和色温模式的切换；或将与控制开关2动作前的亮度和色温模式对应的LED组合4熄灭，并将下一亮度和色温模式对应的LED组合4按照相应的亮度点亮，即LED组合4的亮度和色温同时改变，实现亮度和色温模式的切换。
具体地，本申请中的处理器3包括存储处理器U2、控制处理器U1及多个驱动处理器，请参照图2，图2为本发明提供的一种存储处理器和控制处理器及部分连接关系的结构示意图，存储处理器U2能够存储控制开关2动作前的亮度和色温模式，控制处理器U1检测到控制开关2于预设时间内进行了预设次数的动作后输出和下一亮度和色温模式对应的控制信号，也即输出和存储处理器U2记录的亮度和色温模式的下一亮度和色温模块对应的LED组合4点亮的控制信号，以使各个驱动处理器分别在接收到控制与自身连接的LED组合4点亮的控制信号后控制相应的LED组合4按照与控制信号对应的亮度点亮，没有接收到控制与自身连接的LED组合4点亮的控制信 号后将相应的LED组合4熄灭，或保持相应的LED组合4的熄灭状态，从而实现对亮度和色温模式的切换，满足用户的需求。
此外，需要说明的是，图2中的L端和N端通过控制开关2和电源1连接，电阻R1和电容C5用于滤波，电阻R8和电阻R9用于限流和降压，开关管D2用于稳压，电容C3和C3X用于滤波，电阻R12和电阻R13用于降压，电容C1和电容C1X用于滤波，开关管D1和电阻R10用于整流与降压。
作为一种优选的实施例，LED组合4包括第一LED组合41和第二LED组合42；
第一LED组合41的亮度和色温与第二LED组合42的亮度和色温不同；
驱动处理器包括：
第一驱动处理器U4及第二驱动处理器U3；
第一驱动处理器U4的信号输入端与控制处理器U1的第一信号输出端连接，输出端与第一LED组合41连接，用于在接收到控制处理器U1发送的第一控制信号时，控制第一LED组合41按照与连续接收到的第一控制信号的次数对应的亮度点亮，并在未接收到第一控制信号时，将第一LED组合41熄灭；
第二驱动处理器U3的信号输入端与控制处理器U1的第二信号输出端连接，输出端与第二LED组合42连接，用于在接收到控制处理器U1发送的第二控制信号时，控制第二LED组合42按照与连续接收到的第二控制信号的次数对应的亮度点亮，并在未接收到第二控制信号时，将第二LED组合42熄灭；
控制处理器U1具体用于在控制开关2于预设时间内进行了预设次数的动作后通过第一信号输出端输出第一控制信号和/或通过第二信号输出端输出第二控制信号，以将各个LED组合4于存储处理器U2存储的亮度和色温模式切换至下一亮度和色温模式。
本实施例以两个LED组合4和两个驱动处理器为例，第一LED组合41的亮度和色温与第二LED组合42的亮度和色温不同，并且第一驱动处理器U4与第一LED组合41连接，第二驱动处理器U3与第二LED组合42连接。
当第一驱动处理器U4接收到控制处理器U1发送的控制第一LED组合 41点亮的控制信号，也即第一控制信号时，控制第一LED组合41按照与连续接收到的第一控制信号的次数对应的亮度点亮，并在没有接收到第一控制信号时，将第一LED组合41熄灭，或保持第一LED组合41熄灭的状态。
当第二驱动处理器U3接收到控制处理器U1发送的控制第二LED组合42点亮的控制信号，也即第二控制信号时，控制第二LED组合42按照与连续接收到的第二控制信号的次数对应的亮度点亮，并在没有接收到第二控制信号时，将第二LED组合42熄灭，或保持第二LED组合42熄灭的状态。
控制处理器U1通过输出第一控制信号和/或第二控制信号，从而仅使第一驱动处理器U4控制第一LED组合41按照与连续接收到的第一控制信号的次数对应的亮度点亮或仅使第二驱动处理器U3控制第二LED组合42按照与连续接收到的第二控制信号的次数对应的亮度点亮，又或者使第一驱动处理器U4按照连续接收到的第一控制信号的次数，第二驱动处理器U3按照连续接收到的第二控制信号的次数控制第一LED组合41和第二LED组合42分别按照相应的亮度同时点亮，从而实现亮度和色温模式的切换，满足用户的要求。
例如，当第一驱动处理器U4第一次接收到第一控制信号时，控制第一LED组合41的亮度为最大亮度的70％；当第一驱动处理器U4连续第二次接收到第一控制信号时，控制第一LED组合41的亮度为最大亮度的50％。
需要说明的是，请参照图2，图2中控制处理器的DIM1端口即为第一信号输出端，控制处理器U1的DIM2端口即为第二信号输出端，请参照图3和图4，图3为本发明提供的第一LED组合及第一驱动处理器的结构示意图，图4为本发明提供的第二LED组合及第二驱动处理器的结构示意图，图3中的第一驱动处理器U4的DIM1端口为第一驱动处理器U4的信号输入端与控制处理器U1的第一信号输出端DIM1连接，图4中的第二驱动处理器U3的DIM2端口为第二驱动处理器U3的信号输入端与控制处理器U1的第二信号输出端DIM2连接。
需要说明的是，本申请中图2、图3和图4中的电路可分别焊在对应的焊盘上，控制处理器U1和驱动处理器之间由电路来进行相应的控制信号的传递，且控制信号通常为直流电。
需要说明的是，当第一LED组合41的亮度和色温较高时，因此，其功率也较高，为了使第一LED组合41能够正常点亮，可设置两个第一驱动芯片与第一LED组合41连接，即第一驱动芯片U4和U5，从而满足第一LED组合41的功率需求，请参照图3。
此外，图3和图4中的电阻R2、电阻R6和电阻R7用于降压。
作为一种优选的实施例，驱动处理器具体用于在接收到控制处理器发送的控制信号时，控制与自身连接的LED组合按照与控制信号对应的功率或电压点亮，并在未接收到控制信号时控制与自身连接的LED组合熄灭。
本实施例中，申请人考虑到可以通过改变LED的功率或电压，实现对各个LED组合4的亮度的改变，从而增加亮度和色温模式的数量，进一步满足用户的需求。
具体地，当LED的功率为最大功率时，LED的亮度也最大，当LED的功率为最大功率的70％时，LED的亮度也即为最大亮度的70％。
作为一种优选的实施例，驱动处理器为RM9010GB型号的芯片。
本实施例中，驱动处理器为RM9010GB型号的芯片，不仅能够基于相应的控制信号将与自身连接的LED组合4点亮或熄灭，还具有成本低，操作简单的特点。
当然，本申请并不限定驱动处理器为RM9010GB型号的芯片，能够实现对LED组合4点亮或熄灭地控制即可。
作为一种优选的实施例，还包括：
输入端通过控制开关2与电源1连接，输出端与处理器3的电源1输入端连接的整流模块BD，用于将电源1输入的交流电整流为直流电，以为处理器3供电。
本实施例中还设置了整流模块BD，请参照图2，整流模块BD能够在电源1为交流电时对交流电进行整流，从而输出直流电为处理器3供电，保证处理器3的正常工作。
此外，整流模块BD可以但不限定为由二极管构成的全桥电路，能够实现对交流电的整流即可。
作为一种优选的实施例，处理器3还用于在控制开关2断开且在预设时 间内并未重新导通时控制各个LED组合4熄灭，并在控制开关2重新导通后控制各个LED组合4于控制开关2断开前的亮度和色温模式重新点亮或在控制开关2重新导通后控制各个LED组合4按照预设第一亮度和色温模式点亮。
本实施例中，申请人考虑到用户将控制开关2断开且在预设时间内并未将控制开关2重新导通时，即为用户进行了关灯操作，此时，处理器3将各个LED组合4熄灭，并在用户重新使用灯，即将控制开关2重新导通时，仍将各个LED组合4按照控制开关2断开前的亮度和色温模式点亮，也即控制开关2重新导通后于控制开关2断开前的亮度和色温模式一致，以满足用户的需求；或在控制开关2重新导通时控制各个LED组合4按照预设第一亮度和色温模式点亮，具体情况依照是否设置了用于存储控制开关2断开前的亮度和色温模式的处理器而定。
需要说明的是，用户重新将控制开关2导通后，若再次对控制开关2进行操作，例如于预设时间内使控制开关2进行预设次数的动作，处理器3继续对亮度和色温模式进行切换，以保证用户的需求。
请参照图5，图5为本发明提供的一种照明系统的结构示意图，该照明系统包括如上述的LED的控制电路，还包括多个LED组合4。
对于本发明提供的一种照明系统的介绍请参照上述LED的控制电路的实施例，本发明在此不再赘述。
作为一种优选的实施例，各个LED组合4分别包括多个LED，且各个LED组合4的色温各不相同。
本申请中的各个LED组合4分别包括多个LED，且各个LED组合4中LED的可以设置为相同的个数，从而通过设定在不同模式下LED的功率从而实现对亮度的改变，各个LED组合4中LED的可以设置为各不相同的个数，从而能够直接通过切换LED组合4的点亮或熄灭，实现对亮度的改变，本申请对此不作限定。例如，请参照图3和图4，图3和图4中的两个LED组合4中的LED的数量不同，因此，两个LED组合4的最大亮度不同。
此外，各个LED组合4的色温各不相同，能够保证分别控制不同的LED 组合4点亮时，能实现色温的切换。
作为一种优选的实施例，各个LED组合4中的各个LED依次连接，且首端的LED的输出端与处理器3的控制端连接，尾端的LED的输入端与直流电源连接；
处理器3具体用于在控制开关2于预设时间内进行了预设次数的动作后通过控制端将相应的LED的输入端的电压拉低或升高，以将相应的LED组合4于控制开关2动作前的亮度和色温模式切换至下一亮度和色温模式。
请参照图3和图4，可见，图3和图4中的各个LED首尾相连，由于图3中的LED的数量较多，图3中的LED分为两组，每组中的LED首尾相接后，两组LED并联，且首端的LED的输出端与处理器3的控制端连接，尾端的LED的输入端与直流电源连接，处理器3通过将LED的输入端的电压拉低，实现将LED点亮或将其亮度提高，处理器3通过将LED的输入端的电压升高，实现将LED熄灭或将其亮度降低，从而实现亮度和色温的切换。

  4. 如权利要求3所述的LED的控制电路，其特征在于，所述驱动处理器具体用于在接收到所述控制处理器发送的所述控制信号时，控制与自身连接的所述LED组合按照与所述控制信号对应的功率或电压点亮，并在未接收到所述控制信号时控制与自身连接的所述LED组合熄灭。
  5. 如权利要求1-4任一项所述的LED的控制电路，其特征在于，还包括：
    输入端通过所述控制开关与所述电源连接，输出端与所述处理器的电源输入端连接的整流模块，用于将所述电源输入的交流电整流为直流电，以为所述处理器供电。
  6. 如权利要求1-4任一项所述的LED的控制电路，其特征在于，所述处理器还用于在所述控制开关断开且在所述预设时间内并未重新导通时控制各个所述LED组合熄灭，并在所述控制开关重新导通后控制各个所述LED组合于所述控制开关断开前的亮度和色温模式重新点亮或在所述控制开关重新导通后控制各个所述LED组合按照预设第一亮度和色温模式点亮。
  7. 一种照明系统，其特征在于，包括如权利要求1-6任一项所述的LED的控制电路，还包括多个所述LED组合。
  8. 如权利要求7所述的照明系统，其特征在于，各个所述LED组合分别包括多个LED，且各个所述LED组合的色温各不相同。
  9. 如权利要求8所述的照明系统，其特征在于，各个所述LED组合中的各个所述LED依次连接，且首端的所述LED的输出端与所述处理器的控制端连接，尾端的所述LED的输入端与直流电源连接；
    所述处理器具体用于在所述控制开关于所述预设时间内进行了所述预设次数的动作后通过控制端将相应的所述LED的输入端的电压拉低或升高，以将相应的所述LED组合于所述控制开关动作前的亮度和色温模式切换至下一亮度和色温模式。
