Description

一种开关调光LED灯 技术领域
本发明涉及一种LED灯，具体是一种用开关进行调光操作的LED灯。
背景技术
LED灯具的室内应用方兴未艾。目前在许多用于传统白炽灯、节能灯灯具上的LED灯越来越多地被家庭接受。此类LED灯都是一体化的，与传统灯具外形类似而同样采用标准灯头。作为室内照明来讲，能够对灯具的光输出进行调节正成为一个大众化的需求。
现阶段大部分家庭原有的灯具控制器，多数仅为通断开关，而没有调光器，若要使用可调光灯具，则需要更换开关线路等预埋设施，十分不便。因此，在不用去更换开关或重新布线的前提下,仅通过更换特别的LED灯来达到调光功能要求，这样的LED产品就应运而生。
专利号CN200910222268.9公开了一种用开关调光的LED灯，极大程度上解决了上述需求的问题。不过此类产品也有它自身的弱点，即开关调光操作并不可靠，无法避免地，容易被来自开关输入线的干扰影响，使灯内电路发生误判操作而自行改变灯泡亮度。并且这种易受干扰的装置，在被开关通断操作时，因各种原因引起的抖动、接触不良等问题使得灯泡亮度发生不受控的状况。
发明内容
本发明的目的在于提供一种开关调光LED灯，以解决现有技术LED灯调光时易受干扰、不稳定的问题。
本发明一种开关调光LED灯，包括结构件、光学器件、LED模块和驱动板，其中驱动板包括整流电路、开关检测单元、逻辑控制单元和LED驱动单元，所述的开关检测单元包括一状态计数器电路和一开关检测电路；所述状态计数器电路，其计数端连接开关检测电路的输出端，其输出端连接开关检测单元以外的逻辑控制单元输入端。
以上是基本的方案。如果作进一步改进，可得到较优选的方案：
所述开关检测单元的开关检测电路其采样输入连接在驱动板整流电路之前，且开关检测单元的开关检测电路包括半波整流电路。
所述开关检测单元结构可以是：包括一整流二极管、一限流电阻和一稳压电路，所述稳压电路包括一稳压二极管，第一电阻和一电容；所述第一电阻与电容均与稳压二极管并联，所述稳压二极管正极接地；所述整流二极管正极通过限流电阻连到电路开关输出，所述整流二极管负极接所述稳压二极管负极。
LED驱动单元可采用非隔离降压型恒流DC-DC方式，其电路可包括一肖特基二极管、一续流电感、一滤波电容、一开关MOS管和一电流采样电阻；肖特基二极管负极和滤波电容第一端接电源输入正极，肖特基二极管正极、续流电感第一端和开关MOS管漏极连接；开关MOS管栅极连接所述逻辑控制单元接收控制信号，源极与电流采样电阻连接并作为采样点连接并反馈给所述逻辑控制单元；整个电路电源输入正极作输出正极接LED模块正极，续流电感第二端与滤波电容第二端连接作输出负极接LED模块负极。
作为本发明的技术方案的拓展方案，可作如下改进：
可将所述LED驱动单元分为两路彼此独立输出，一路接驳高色温的LED模块，另一路接驳低色温LED模块。
或可将所述LED驱动单元分为三路彼此独立输出，一路接驳红光LED模块，另一路接驳蓝光LED模块，最后一路接驳绿光LED模块。
本发明采用以上方案，相对于现有技术的方案而言其有益效果是：
1． 在不更换开关或重新布线的前提下，具有调光的功能；
2． 不论是接入的电网不稳定，还是用于调光的普通电源开关易抖动，本发明的调光操作采用可延时判断的状态计数器，所以调光操作和持续工作状态均可靠而有效，发生误操作几率很小。
3． 独有的调光方式不但可以用于调节灯光明暗，更因为不同的驱动组合来调节LED灯的色温和色彩。

具体实施方式
以下是结合附图及实施例对本发明的具体说明：
图1是本发明的概要图，开关调光LED灯，包括结构件、光学器件、LED模块5和驱动板，其中驱动板包括整流电路1、开关检测单元2、逻辑控制单元3和LED驱动单元4，所述的开关检测单元2内包括一状态计数器电路21和一开关检测电路22；所述状态计数器电路21，其计数端连接开关检测电路22的输出端，其输出端连接开关检测单元2以外的逻辑控制单元3输入端。
图2是本实施例1的电路图，图中模块U1包含了开关检测单元2和逻辑控制单元3。图3作为此例中开关检测单元2的开关检测电路22被单独列出。限流电阻R1在整灯整流电路1之前接入交流市电，再经过二极管D4得到半波整流的电流，经过有稳压二极管ZD4、电阻R6和电容C5组成的稳压电路，最终从GP1端输出一个5.1V峰值的工频方波，GP1连接U1内部的状态计数器21。
电阻R4、R5、二极管D1、开关MOS管Q1、电感L、电容C3组成了LED驱动电路，开关MOS管Q1的栅极通过R4接模块U1的GATE端。
另外，在U1模块中还有一档位计数器，此计数器用于对开关次数进行计数，以确定不同的LED灯光通输出档位。
以上是对电路结构的介绍。下面对工作流程进行说明：
图4是图2实施例1的总程序图；图5、图6、图7和图8都是图4中总程序的各子程序；其中，图5是初始化子程序，图6是开关检测单元子程序，图7是档位调节子程序图，图8是档位输出子程序。
本实施例的灯接入室内市电线路后，第一次接通开关即进入图5的初始化子程序，该程序为状态计数器21赋初始值30，又为档位计数器赋值1；初始化子程序完毕即进入图6的开关检测单元子程序。需要说明的是，此子程序所控制的电路部分会每隔4.096ms对图3中GP1端进行电平采样。在图6的开关检测子程序中，一开始即对GP1采样电平进行判断。
按一般操作的习惯，若此时用户保持开关一直闭合，即LED灯是持续点亮状态。此时在开关检测子程序中，GP1检测到为高电平和低电平的持续时间相同（方波），高电平期间状态计数器21值就增加5，低电平期间就减1， 因此，状态计数器21值终究会增加。增加到若已经大于30，就直接给状态计数器21赋值50后，子程序退出，将开关状态标志置1后退出， 若已经大于40，则直接给状态计数器21赋值50后就退出子程序。
第二种情况，用户进行调光操作：在灯已经持续点亮的情况下，关闭电源开关，然后1.5秒之内再次闭合开关。此时，由于电源开关的持续关断（1.5秒之内，此时限内不影响档位调节），在0.2秒之内，状态计数器会21被减到0，此时开关闭合标志被置0，且由于开关已经断开，灯灭。再打开开关时，状态计数器21值继续递增，直到开关闭合标志被置1后，就进入档位调节程序。
第三种情况，用户进行关灯操作：在灯已经持续点亮的情况下，关闭电源开关超过1.5秒不再打开。此时开关检测子程序将开关闭合标志置0后退出，且档位调节程序重新将档位计数器赋值为1，即初始化状态。
主程序每次运行完并退出开关检测子程序后，都会以开关闭合标志作为档位调节子程序的依据。如图7所示档位调节程序，在开关闭合标志为0超过1.5秒时，判断为关灯操作，触发的动作是将档位计数器置1；若用户在1.5秒之内再次打开灯，则判断为调光操作，触发动作就是将档位在现有基础上进一档，保持在1,2和3档单向轮换，实现3个档位的输出。
对于每个档位，在电路中靠档位输出程序控制LED模块的驱动电流，由于LED光通和其驱动电流基本成正比，所以通过LED驱动电路控制其输出电流即可实现不同的光通量输出状态，如图8所示就是档位设定的对应图和输出流程。
综上可知，本实施实例的开关调光LED灯，上电后即输出100%的光通，以后每次1.5秒内的关灯再开灯操作均视为一次调光操作，而顺次的调光操作使LED灯的光输出在100%-50%-10%三个档位上不停轮换。在任何一个档位状态中，若关断开关超过1.5秒，系统就判断为关灯操作，LED灯的光输出被重置为100%。
由于状态计数器21的存在，每次关断再打开电源开关的机械操作本身并不会被认为是调光操作，而是被并赋予状态标记而延时判断才得到结论，因而不会因为电压波形不良、开关抖动等微小干扰发生误判的情况。
实施例2，作为本发明的拓展方案，如图9所示，是本发明实施例2概要图。此方案将LED驱动单元分为独立的两路，分别接驳高色温LED模块和低色温LED模块。如此，通过对原本图1中的逻辑控制单元和LED驱动单元进行拓展，使得档位输出不再是一个变量，而是两路变量的组合。此两路变量分别控制LED驱动单元中各路的驱动电流，就会实现不同电流的高/低色温LED组合发光方式，所得到的结果就会是不同色温的混光输出。通过LED灯开关的反复切换，用户就可实现此不同的色温输出。
实施例3，利用同样的拓展法则可得到图10的调色方案，由于红、蓝、绿的混色特点，可得到无数种混色输出组合，这里将LED驱动单元和逻辑驱动单元同时拓展为3路，使得档位输出是3路变量的组合，如此就可预设不同的组合方式，而在实际使用中通过LED灯开关的反复切换得到。
以上所述，仅为本发明较佳实施例，不能依此限定本发明实施的范围，即依本发明专利范围及说明书内容所作的等效变化与修饰，皆应仍属本发明涵盖的范围内。
工业实用性
本发明一种开关调光LED灯，构思巧妙、涉及合理、使用方便，不但可直接用一个开关实现调光的功能，且不论是接入的电网不稳定，还是用于调光的普通电源开关易抖动，其调光操作采用了可延时判断的状态计数器，所以调光操作和持续工作状态均可靠而有效，发生误操作几率很小。同时此方案不但可以调节LED灯明暗，也可以用于调节色温和调节色彩。
