具体实施方式
为了使本发明所要解决的技术问题、技术方案及有益效果更加清楚、明白，以下结合附图和实施例，对本发明进行进一步详细说明。应当理解，此处所描述的具体实施例仅仅用以解释本发明，并不用于限定本发明。
实施例一
本实施例提供了一种光控灯具，如图1所示，该光控灯具1包括灯具结构件11和安装在灯具结构件11内的照明灯和开关装置12，开关装置12用于控制照明灯的通断。开关装置12包括连接在一起的开关电片121和磁铁122，磁铁122可受磁场的驱动而移动进而带动开关电片121移动实现控制照明灯的通断。该光控灯具1在实际安装和应用时，由于其采用的是磁场驱动原理，磁场具有一定的穿透性，用于产生磁场的装置可以安装固定在灯具结构件11外，而无需在灯具结构件11上开孔，也就不再需要考虑因开孔而带来的灯具结构件11的防水问题，用于产生磁场的装置安装在灯具结构件11外后，通过磁场驱动磁铁122移动，磁铁122进而带动开关电片121移动导通或断开电路从而实现控制照明灯的通电工作和断电关闭。
值得说明的是，用于产生磁场的装置可以是多种多样的，例如：人工控制或自动控制转向换级的磁控件，利用同性相吸、异性相斥原理通过磁控件的磁场驱动光控灯具1的磁铁122的移动；可改变磁场方向的电磁铁，通过电路改变电磁场的方向，利用同性相吸、异性相斥原理通过电磁铁的磁场驱动光控灯具1的磁铁122的移动。
实施例二
本实施例提供了一种光控系统，如图2和图3所示，该光控系统包括光控组件100和光控灯具200。光控组件100包括感应件、控制器120和电磁装置130，感应件用于感应光照强度，控制器120用于根据感应件反馈的光照强度产生控制电流，电磁装置130用于根据控制器120产生的控制电流改变磁场以实现控制光控灯具200的通断。值得说明的是，改变磁场包括磁场的从无到有、从有到无、磁场大小的改变和磁场的方向的改变等等。光控灯具200包括灯具结构件210和安装在灯具结构件210内的照明灯和开关装置220，开关装置220用于控制照明灯的通断。在本实施例中，该光控灯具200还包括两个导电片230，两个导电片230间隔设置。开关装置220包括靠近导电片230的开关电片221和远离导电片230的磁铁222，开关电片221与磁铁222连接在一起，磁铁222可受磁场的驱动而移动使得开关电片221导通或断开两个导电片230以实现控制照明灯的通断。值得说明的是，两个导电片230和一个开关电片221为用于实现通断的一组，而在实际应用时，也可以设置多组的两个导电片230和一个开关电片221，例如同时控制零火线通断。光控组件100安装在灯具结构件210外，由于通过磁场进行控制，灯具结构件210无需打孔。
结合图3和图4所示，晚上随着日光光照强度降低，达到控制器120设定的动作阈值后，控制器120产生控制电流，电磁装置130产生磁场，灯具结构 件210内的磁铁222受电磁装置130产生的磁场的驱动而移动，开关电片221与两个导电片230接触实现导通，照明灯通电工作；早上随着日光光照强度升高，达到控制器120设定的动作阈值后，控制器120产生控制电流，电磁装置130产生磁场，灯具结构件210内磁铁222受电磁装置130产生的磁场的驱动而移动，开关电片221脱离两个导电片230实现断开，照明灯停止通电。本实施例中的光控系统，光控灯具200的灯具结构件210无需开孔，光控组件100可以直接安装在灯具结构件210外，同时能够保证光控效果。
在本实施例中，如图2、图3和图4所示，当感应件反馈的光照强度低于预设的第一动作阈值时，控制器120产生正向控制电流，电磁装置130产生与灯具结构件210内的磁铁212磁性相同的磁场，同性磁场相斥，开关电片211靠近两个导电片230移动而与两个导电片230接触实现导通，照明灯通电工作；当感应件反馈的光照强度高于预设的第二动作阈值，控制器120产生反向控制电流，电磁装置130产生与灯具结构件210内的磁铁222磁性相反的磁场，异性磁场相吸，开关电片221远离两个导电片230移动实现断开，照明灯停止通电。在本实施例中，控制电流为设定时长的脉冲电流，例如10秒。
在本实施例中，如图5所示，开关装置220还包括开关外壳223，开关电片221与磁铁222之间设有滑杆224，滑杆224滑插在开关外壳223。开关外壳223内设有隔档部2231，滑杆224上设有限位部2241，磁铁222受驱动移动时，限位部2241越过隔档部2231。开关电片221与两个导电片230接触时，限位部2241位于隔档部2231的下方，电磁装置130的磁场撤去后，由于限位部2241和隔档部2231之间的相互限位，开关电片221保持与两个导电片230接触；开关电片221远离两个导电片230移动后，限位部2241位于隔档部2231的上方，由于限位部2241和隔档部2231之间的相互限位，开关电片221保持位置。在 本实施例中，隔档部2231的上下端面设有辅助斜面，限位部2241的上下端面设有辅助斜面，以便于磁铁222受驱动时限位部2241越过隔档部2231。
在本实施例中，如图2所示，光控组件还包括用于提供电能的电池140。在本实施例中，感应件为光伏板110，光伏板110一方面感应光照强度，另一方面通过控制器120为电池140充电。光伏板110电压随日光光照强度降低而降低，升高而升高，控制器120可以通过检测光伏板110的电压来间接得知光照强度的大小。在本实施例中，光控组件100还包括外壳150，光伏板110安装在外壳150的外表面，控制器120、电磁装置130和电池140安装在外壳150内，外壳150安装在灯具结构件210外。在其他实施例中，光伏板110也可以为外壳150的一部分。
值得说明的是，本发明的原理为通过磁场驱动实现通断从而不需要在灯具结构件210上开孔，本实施例仅为其中一种具体实施方式的举例。在其他实施例中，也可以是，控制器120产生相同的控制电流，电磁装置130产生与灯具结构件210内的磁铁222相反的磁场，开关装置220采用类似多色按压式圆珠笔的结构，也可以达到同样的效果。在其他实施例中，也可以是，控制器120使电磁装置130始终供电存在磁场使开关装置220保持导通或断开状态，开关装置220结构可以更加简单。在其他实施例中，光控组件100也可以是其他的提供电能的方式，例如与市电连接供电。
本申请另一实施例提供了一种调光系统，如图6所述，该调光系统包括调光控制组件31和灯具32，灯具32包括灯具结构件321和安装在灯具结构件321内的调光模块，调光模块包括磁敏电阻322。灯具结构件321内安装有照明模块，调光模块用于调节控制照明模块的亮度。调光控制组件31安装在灯具结构件321外，调光控制组件31包括控制器311和电磁装置312，控制器311包括通信模 块，控制器311通过通信模块接收外部集中控制器发送的调光信号，并依据接收的调光信号改变电流大小。电磁装置312与控制器311连接，控制器311改变电流大小后，电磁装置312产生的磁场强度改变从而实现调光。值得说明的是，外部集中控制器可以是外部智能遥控器、控制平板、控制电脑或可实现控制的智能手机等等，外部集中控制器与调光控制组件的控制器311之间的通信方式既可以是有线也可以是无线。
该调光系统在使用时，当需要把灯具32亮度由量变暗时，先通过外部集中控制器发送亮度由量变暗的调光信号，调光控制组件31的控制器311通过通信模块接收该亮度由量变暗的调光信号后，给电磁装置312电路加大电流，电磁装置312产生的磁场强度增大，灯具结构件321内的调光模块的磁敏电阻322感受到磁场强度增大时，磁敏电阻322的阻值降低，调光模块的输出端电压降低，照明模块由量变暗；当需要把灯具32亮度由暗变亮时，先通过外部集中控制器发送亮度由暗变亮的调光信号，调光控制组件31的控制器311通过通信模块接收该亮度由暗变量的调光信号后，给电磁装置312电路减小电流，电磁装置312产生的磁场强度减小，灯具结构件321内的调光模块上的磁敏电阻322感受到减小的磁场强度时，磁敏电阻322的阻值增大，调光模块的输出端电压增大，灯具32由暗变亮。本实施例中的调光系统，通过电磁装置312的磁场与调光模块的磁敏电阻322的配合实现调光，灯具结构件321无需开孔即可将调光控制组件31安装在灯具结构件321外，结构设计简单，且安装简便。
在本实施例中，如图1所示，调光控制组件31还包括用于给控制器311提供电能的电池313。在其他实施例中，控制器311也可以是直接连接市电或其他外部电源。在本实施例中，调光控制组件31还包括光伏板314，光伏板314通过控制器311给电池313充电，节能减排。在本实施例中，调光控制组件31还 包括外壳315，光伏板314安装在外壳315的一外表面，控制器311、电磁装置312和电池313安装在外壳315内。在其他实施例中，光伏板314也可以为外壳315的一部分。
在本实施例中，如图1所示，调光模块还包括与磁敏电阻322电连接的LM317芯片323，起控制和稳压作用。在本实施例中，灯具32还包括安装在灯具结构件321内的可调光电源324，可调光电源324的调光端与调光模块的Vout端相接。在本实施例中，可调光电源324为0-10VDC可调光电源324，调光模块为0-10VDC调光模块。
以上具体实施例仅仅是对本发明的解释，其并不是对本发明的限制，本领域技术人员在阅读完本说明书后可以根据需要对以上实施例做出没有创造性贡献的修改，但只要在本发明的权利要求范围内都受到专利法的保护。
