Description

万用LED子母灯 技术领域
本发明涉及照明灯具领域技术，尤其是指一种万用LED子母灯。
背景技术
因环保节能之需求，目前的家用照明已由传统的卤素灯被LED灯取代，因而可省下90%的电力。但由于LED需使用定电流的电源适配器及调光器，还有不同功率的LED或不同的排列组合散热模块，给LED发展带来了以下困扰：1、只要有一个环节没考虑好，均会使LED产生故障，寿命减短，频闪等各种缺陷。原本LED在正常使用下的可达到5年或10年以上，而因上述原因，而使用寿命严重减短。2、LED的调光有不同的方式及不同的回路组合，如电压不同、电流不同、调光讯号不稳定三种弊病，造成成本过高，相互的配件不匹配和严重的闪烁，增加成本。
发明内容
有鉴于此，本发明针对现有技术存在之缺失，其主要目的是提供一种万用LED子母灯，其控制器的电路能提供不频闪、稳定之驱动电流。
为实现上述目的，本发明采用如下之技术方案：
一种万用LED子母灯，包括子LED灯、母LED灯和调节LED灯之光通量的控制器，该控制器内置PWM调光模组，该PWM调光模组的电路包括用于驱动母LED灯的第一LED驱动电路、用于驱动子LED灯的第二LED驱动电路、连接于第一和第二LED驱动电路的可编程式微控制器、连接于可编程式微控制器的双控制开关电路，该第一和第二LED驱动电路均由高频电路和DC/DC PWM电流放大器组成。
优选的，所述控制器上设置子LED灯控制开关和母LED控制开关，对应之双控制开关电路分别连接该子母灯控制开关，以及该子母灯控制开关的内部安装有指示LED灯。
优选的，所述子母灯控制开关是按键式的微型控制开关，或者是触摸式薄型电容式触摸点。
优选的，所述可编程式微控制器还连接有一低压差电压调整器。
优选的，所述可编程式微控制器是记忆体IC。
优选的，所述LED灯和控制器可拆式安装于灯座上，并且该灯座的底部还配设有一独立的可拆式电源适配器。
优选的，所述灯座由可分离的上下两段支架组成，上支架又包括大灯支架和小灯支架，该下支架与电源适配器之间、下支架与控制器之间、控制器与大灯支架和小灯支架之间、该大灯支架与母LED灯之间、小灯支架与子LED灯之间均设有快速接头。
优选的，所述电源适配器内置电源模组，该电源模组的电路包括电磁干扰滤波器、桥式整流器、隔离变压器、整流器、滤波器、比较器及电压基准电路、光偶合器、功率因素及脉宽调变切换控制器；该电磁干扰滤波器、桥式整流器、隔离变压器、整流器、滤波器依次相连，该比较器及电压基准电路、光偶合器、功率因素及脉宽调变切换控制器依次相接于滤波器和隔离变压器之间，形成反溃电路。
优选的，所述子母LED灯的结构相同，均包括散热座、超薄高导热硅胶片、LED发光模组以及防眩PC灯罩，该散热座、硅胶片、LED发光模组和PC灯罩依次安装并由螺丝固定。
优选的，所述散热座包括一平面式的圆顶板以及多片一体设于圆顶板底部的散热鳍片，相邻散热鳍片之间彼此分离；该LED发光模组包括LED铝基板以及共压的矩阵排列于LED铝基板上的LED晶片，该硅胶片的正反两面分别接触LED铝基板和散热座的圆顶板，PC灯罩与圆顶板之间具有断差。
本发明与现有技术相比具有明显的优点和有益效果，具体而言，由上述技术方案可知，由于LED驱动电路设置高频电路和DC/DC PWM电流放大器，当可编程式微控制器产生双输出的PWM讯号给双组DC/DC PWM电流放大器，推动LED发光模组，再予高频低压之驱动电流整形后，在高频操作下，能提供输出不频闪的稳定的驱动电流给LED发光模组，因DC/DC PWM电流放大器解决了频闪之缺点，可供输舒适柔和的光和0～100%的调光功能。
此外，由于PWM调光模组的电路具有可编程式微控制器，该可编程式微控制器是记忆体IC，可以记录上一次使用时LED灯的光通量，在下一次使用时，可编程式微控制器自动提取上一次调定的光通量，实现智能记忆，无需重新设定，使用方便。
再者，由于灯座、LED灯、电源适配器和控制器各个零件之间均设有快速接头，不需要太专业的知识即可以快速拆装，可任意组合和更换，便于依据需要更换不同发光功率的LED灯，以及对应配对满足供电需求的电源适配器。此外，各部件拆除后，占用的包装空间减小，便于包装运输和搬运。
以及，由于子LED灯控制开关和母LED控制开关，可以是按键式的微型控制开关，也可以是触摸式薄型电容式触摸点，并且该控制开关也可以兼容按键式和触摸式两种结构，实现的方式多样，选择性多，组合性高。
还有，由于PC灯罩是防眩灯罩，除了具备防尘、防潮之功能，还具有防眩功能，能够扩散光线，以达到类似单点出光的效率。
最后，电源适配器具有空载低维持电源、高功率因数、高效率隔离驱动电源、符合通用交流全电压输入范围、保护全面，具备防火、过载、过温、短路保护。
总之，经上述电路设计后，使得子母LED灯具有宽电压、高效、省电模式，小型化，易拆换、散热快、高亮度输出、不频闪、无眩光、整体产品轻小薄。

具体而言，如图1-2所示，该LED灯20是子母灯的形式，即由一盏大的母LED灯201和一盏小的子LED灯202组成。该灯座10由可分离的上下两段支架组成，上支架11又包括大灯支架111和小灯支架112。该电源适配器30可拆式连接于下支架12的底端，该母LED灯201可拆式连接于大灯支架111的顶端，子LED灯202可拆式连接于小灯支架112的顶端，该控制器40可拆式连接于上和下支架11、12之间，藉此，使灯具的各个部件可以快速拆装，各部件拆除后，占用的包装空间减小，便于包装运输和搬运，并且，也便于依据需要更换不同发光功率的LED灯20，以及对应配对满足供电需求的电源适配器30。
如图2所示，该下支架12与电源适配器30之间具有快速接头13，使二者易于插拔。以及该下支架12与控制器40之间、控制器40与大灯支架111和小灯支架112之间、该大灯支架111与母LED灯201之间、小灯支架112与子LED灯202之间均设有快速接头13，使各个部件可以相接并且实现电导通。
如图3-6所示，所述LED灯20中，该母LED灯201和子LED灯202仅尺寸不同，二者的结构相同，当然也可以依据需要制作成不同的结构，客户可以自由挑选。本实施例的LED灯20包括散热座21、超薄高导热硅胶片22、LED发光模组23以及防眩PC灯罩24。该散热座21、硅胶片22、LED发光模组23和PC灯罩24依次安装并由螺丝25固定。其中，该散热座21包括一平面式的圆顶板211以及多片一体设于圆顶板211底部的散热鳍片212，相邻散热鳍片212之间彼此分离，能有效增大散热面积，增强散热效率。该LED发光模组23包括LED铝基板231以及密布于LED铝基板231上的LED晶片232，该LED铝基板231兼有通电以及固定LED晶片232的功能，而硅胶片22的正反两面分别接触LED铝基板231和圆顶板211，能快速将LED晶片232的热量传递。此外，该防眩光学PC灯罩24与LED铝基板231有0.3MM段差H，确保LED铝基板231与硅胶片22良好的接触。当然，0.3MM段差H是本实施例的具体结构的数值，依据不同尺寸的LED灯，断差的值可以依实际而变。还有，所述PC灯罩24盖于LED发光模组23外，该PC灯罩24盖除了具备防尘、防潮之功能，还具有防眩功能，能够扩散光线，以达到类似单点出光的效率。
如图7和图8所示，所述控制器40包括外壳41、控制开关42和设于外壳41内的PWM调光模组43。该外壳41由卡扣式组装的第一壳体411和第二壳体412包围而成，该PWM调光模组43安装于外壳41内腔中，该控制开关42设于外壳41上。本实施例中，对应子母两盏LED灯201、202，控制开关42也对应有两个，即子LED灯控制开关421和母LED控制开关422。每个控制开关42对应控制一盏LED灯。该控制开关42可以是按键式的微型控制开关，也可以是触摸式薄型电容式触摸点，并且该控制开关42也可以兼容按键式和触摸式两种结构。当按下或触摸控制开关421或422后，接通子LED灯202或母LED灯201。
如图9和图10所示，所述电源适配器30是外置式的独立电源，其包括外壳31、设于外壳31的市电插头32和安装于外壳31内的电源模组33。该外壳31由相互扣合的第三和第四壳体311、312构成，该电源模组33内置于第三和第四壳体311、312围构成的内腔中。如图9所示，所述快速接头13设于外壳31的顶部，该市电插头32可以设计成由外壳31的侧面伸出，如图11所示，也可以设计成从外壳31的底部伸出，以适用多种插座。以及，该电源适配器30的外壳31可以依据需要而制作成长方体结构或正方体结构，具体形状不作限制。
如图12所示，其显示了控制器40中PWM调光模组43的电路以及电源适配器30中电源模组33的电路。
该电源模组33电路是独立隔离AC转DC电源电路，提供子母双LED灯之超低压（小于48V）的DC输出供电回路。该电源模组33的电路包括电磁干扰滤波器331、桥式整流器332、隔离变压器333、整流器334、滤波器335、比较器及电压基准电路336、光偶合器337、功率因素及脉宽调变切换控制器338。该电磁干扰滤波器331、桥式整流器332、隔离变压器333、整流器334、滤波器335依次相连，该比较器及电压基准电路336、光偶合器337、功率因素及脉宽调变切换控制器338依次相接于滤波器335和隔离变压器333之间，形成反溃电路。市电电源由市电插头32接入220V电压，依次经过电磁干扰滤波器331将干扰信号滤除，经桥式整流器332整流，输入隔离变压器333的初级侧；隔离变压器333的次级侧输出低压电，再经整流器334整流，以及经滤波器335滤波处理输出直流电。而比较器及电压基准电路336、光偶合器337将隔离变压和AC转DC后的电流反馈回来，经功率因素及脉宽调变切换控制器338调节，得到恒定的直流电。由上述模块构成的电源模组33的电路具有以下特点：1、空载低维持电源，2、高功率因数、高效率隔离驱动电源；3、符合通用交流全电压输入范围（85-264V 50/60HZ）；4、保护全面，具备防火、过载、过温、短路保护。
该PWM调光模组43的电路包括用于驱动母LED灯201的第一LED驱动电路431、用于驱动子LED灯202的第二LED驱动电路432、低压差电压调整器433、控制开关电路434、可编程式微控制器435。该第一和第二LED驱动电路431、432相同，均包括有高频电路436和DC/DC PWM电流放大器437。第一LED驱动电路431接母LED灯201，第二LED驱动电路432接子LED灯202，并且该DC/DC PWM电流放大器437连接于可编程式微控制器435，且滤波器335输出的直流电经低压差电压调整器433连接可编程式微控制器435，控制开关电路434也接于可编程式微控制器435。
该可编程式微控制器435是记忆体IC，可以记录上一次使用时LED灯20的光通量，在下一次使用时，可编程式微控制器435自动提取上一次调定的光通量，实现智能记忆，无需重新设定，使用方便。该可编程式微控制器435产生双输出的PWM讯号给双组DC/DC PWM电流放大器437，推动LED发光模组23，再予高频电路436的高频低压之驱动电流整形后，在高频操作下，能提供输出不频闪的平稳电力给LED发光模组23，因DC/DC PWM电流放大器437解决了频闪之缺点，可供输舒适柔和的光和0～100%的调光功能。除此之外，该低压差电压调整器433和可编程式微控制器435之间设有两指示LED灯438，设计时，两指示LED灯438分别对应于子LED灯控制开关421和母LED控制开关422内部，具有夜间指示功能。并且，该两指示LED灯438又可在调光至最高或最低亮度时，产生闪灯（闪烁三下），以利于控制到最亮或最暗的亮度。
在第一和第二LED驱动电路431、432中，该子母LED灯202、201可选用6W/12W/24W/36W，即可取代原来高耗能的钨丝灯泡50W/150W/300W/500W，有效节能。并且子母LED灯202、201的LED晶片232采用共压的矩阵排列，共压设计具有通用性高，组合式方多样的优点。此外，为了满足照明需求，作为一种优选的方案，该母LED灯201的光照可以朝向上方，而子LED灯202的光照朝向下方，因此本实施例将小灯支架112折弯为弧形或直角结构，使子LED灯202向下照射。
综上所述，本发明的设计重点在于：
1，由于灯座10、LED灯20、电源适配器30和控制器40各个零件之间均设有快速接头13，不需要太专业的知识即可以快速拆装，可任意组合和更换，便于依据需要更换不同发光功率的LED灯20，以及对应配对满足供电需求的电源适配器30。此外，各部件拆除后，占用的包装空间减小，便于包装运输和搬运。
2、由于子母灯的驱动电路设计了DC/DC PWM电流放大器437，在高频操作下，能提供输出不频闪的平稳电力给LED发光模组23，因DC/DC PWM电流放大器437解决了频闪之缺点，可供输舒适柔和的光和0～100%的调光功能。
3、由于PWM调光模组43的电路具有可编程式微控制器435，该可编程式微控制器435是记忆体IC，可以记录上一次使用时LED灯20的光通量，在下一次使用时，可编程式微控制器435自动提取上一次调定的光通量，实现智能记忆，无需重新设定，使用方便。
4、由于子LED灯控制开关421和母LED控制开关422，可以是按键式的微型控制开关42，也可以是触摸式薄型电容式触摸点，并且该控制开关42也可以兼容按键式和触摸式两种结构，实现的方式多样，选择性多，组合性高。
5、由于PC灯罩24是防眩灯罩，除了具备防尘、防潮之功能，还具有防眩功能，能够扩散光线，以达到类似单点出光的效率。
6、电源适配器30具有空载低维持电源、高功率因数、高效率隔离驱动电源、符合通用交流全电压输入范围、保护全面，具备防火、过载、过温、短路保护。
总之，经上述电路设计后，使得子母LED灯202、201具有宽电压、高效、省电模式，小型化，易拆换、散热快、高亮度输出、不频闪、无眩光、整体产品轻小薄。
以上所述，仅是本发明的较佳实施例而已，并非对本发明的技术范围作任何限制，故凡是依据本发明的技术实质对以上实施例所作的任何细微修改、等同变化与修饰，均仍属于本发明技术方案的范围内。
