利用本发明，只需 在用户原有的只具备亮度调节功能的 LED 灯具调光布线中加入本发明提供的 LED 可控硅智能电源或 LED 灯具，即可实现对 LED 灯具色温的调节，无需另外单独安装色温调控电路，不用对用户原有调光布线进行改动，安装简单，可广泛推广 。
附图说明
图1：本发明实施例提供的带有色温调节功能的LED可控硅智能电源结构示意图；
图2：本发明实施例提供的带有色温调节功能的LED灯具结构示意图；
图3：本发明实施例提供的上述LED灯具的进一步结构示意图。
 本发明的实施方式
为了使本发明的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本发明进行进一步详细说明。
如图1所示，本发明提供的带有色温调节功能的LED可控硅智能电源1包括相互连接的可控硅模块101及MCU模块102，可控硅模块101用于与LED模组连接，MCU模块102用于通过可控硅模块101调节LED模组的色温。将该LED可控硅智能电源1的可控硅模块101连接在现有调光器与LED模组之间，现有调光器可通过可控硅模块101调节LED模组的亮度，而MCU模块102可通过可控硅模块101调节LED模组的色温，从而实现在现有 调光布线无需改变的情况下增加对 LED 灯具的色温调节 。
本发明实施例中，可控硅模块101具有色温调节模式，MCU模块102只能在可控硅模块101处于色温调节模式时对LED模组进行色温调节。同时，MCU模块102内预装有色温调节程序，对LED模组进行色温调节时，MCU模块102根据色温调节程序控制LED模组的色温循环渐变，在LED模组的色温循环渐变的过程中关闭LED模组时，MCU模块102记录LED模组的当前色温，并在下次启动LED模组时应用该色温。本次启动后，可控硅模块101是否进入色温调节模式是由MCU模块102决定的，具体而言，MCU模块102可检测可控硅模块101上次关闭与本次开启之间的时间间隔，并在时间间隔小于预设值时控制可控硅模块101本次开启后进入色温调节模式。在本实施例中，时间间隔的预设值为3秒，当可控硅模块101上次关闭与本次开启之间的时间间隔小于3秒时，MCU模块102即控制可控硅模块101本次开启后进入色温调节模式。MCU模块102还可实时记录LED模组的亮度或色温，并在下次启动LED模组时对其应用该亮度或色温。可控硅模块101内置有市电交流信号检测单元，用于检测市电交流信号，并将检测到的市电交流信号发送给MCU模块102。
如图2所示，基于上述的LED可控硅智能电源1，本发明还提供了一种带有色温调节功能的LED灯具，包括至少一个如上所述的任意一种LED可控硅智能电源1以及与LED可控硅智能电源1连接的LED模组2。现有的可控硅调光器可通过LED可控硅智能电源1的可控硅模块101连接LED模组2，通过可控硅模块101调节各LED模组2的亮度。而LED可控硅智能电源1的MCU模块102可通过可控硅模块101调节LED模组2的色温，从而实现在现有 调光布线无需改变的情况下增加对 LED 灯具的色温调节 。LED可控硅智能电源1的工作电压为交流195V-265V，最大亮度时的输出电流为500MA。
如图3所示，在选择该LED灯具的LED模组2时，可选择包括至少两个LED发光单元201的LED模组2，各LED发光单元201之间具有不同的色温。例如，LED模组2包括两个LED发光单元201，两个LED发光单元201分别为冷色光源和暖色光源。将LED模组2的各LED发光单元201都与可控硅模块101连接，这样，MCU模块102可通过调节可控硅模块101输出到各LED发光单元201的电流比例的方式调节LED模组2的色温。根据所选择的LED模组2的LED发光单元201的个数，可控硅模块101可设置多个输出端，每个输出端连接一个LED发光单元201。
以下为通过本发明调节LED模组2色温的步骤举例：
1 、开灯，并在开灯后3秒内关灯，并再次开灯；
2 、再次开灯时，LED可控硅智能电源1进入色温调节模式，此时，LED模组2按照'暖白-正白-冷白-暖白'的顺序无极循环渐变；
3 、在LED模组2的色温无极循环渐变的过程中，当变化到想要的色温时，关灯；
4 、再次开灯，LED模组2的色温就为上次关灯时的色温。
5 、如果不喜欢当前色温，可通过步骤2-4 重新调节。
本发明只需在传统的只具备亮度调节功能的可控硅调光器的基础上增加本发明提供的LED可控硅智能电源1，利用原可控硅调光器的布线即可实现对LED模组2发光色温的调节，可兼容传统的可控硅调光器，安装方便。
以上所述仅为本发明的较佳实施例而已，并不用以限制本发明，凡在本发明的精神和原则之内所作的任何修改、等同替换和改进等，均应包含在本发明的保护范围之内。
