Description

LED模块化驱动电路 技术领域
本实用新型涉及LED驱动控制技术领域，尤其涉及一种LED模块化驱动电路。
背景技术
在绿色发展、节能减排的背景下，各类物品的能耗成为消费者考虑的重要因素之一，其中灯具作为现代人们不可或缺的物品，其环保性能备受关注，LED灯具相比于传统的照明灯具拥有绿色、环保节能等特点而符合当今时代的发展背景，并随着人们生活水平、品质需求以及LED照明产业技术的不断提高，LED灯具的产品外观款式和使用功能也随之得到相应的迭代升级，从开始最基本的节能照明，然后过渡到可控硅调光照明，再到现在目前市场上方兴未艾的具有无线控制调光调色功能的智能照明，LED灯具丰富的款式和功能备受消费者青睐。
不同于传统的照明器具，LED灯珠不能直接地接入交流市电电网，而是要通过驱动电路先将交流市电转化为直流电源，然后再进行驱动。因此，LED灯具主要包括LED灯珠和与与灯珠相适配的驱动部分。目前大多数的无线控制的照明灯具是采用隔离或非隔离开关型电源电路技术，特别地以反激式开关电源为主，其主要包括整流电路、功率级电路和控制电路。这些功率级电路主要内含有开关管，例如三极管。首先整流电路接收交流市电，经过整流电路后进入至功率级电路，由功率级电路进行电压转换，控制电路用于控制功率级电路中主功率开关管的通断，从而实现恒流驱动LED发光，然而由这类驱动电源电路设计复杂，制造成本高，从而使用相应的灯具产品价格难以被降低。
因此，市面上还出现了线性恒流型驱动电路，相对于开关电源型驱动，线性恒流型驱动电路的线路简单，需要的***器件相比于比开关电源型驱动的电路少，便于实现光电一体化集成，并且线性恒流型驱动电路没有开关电源型驱动由于开关频繁开启和关断引起的EMI问题，使得线性恒流型驱动电路成为LED驱动电路的重点研究领域。因此市面上的一些无线控制的照明灯具采用了这类技术，但是由于其电路设计排布或参数设置(比如主电路的浪涌保护、过流保护，以及各 个子电路的整流、滤波、稳压恒压、信号采样反馈等)不合理，从而容易造成这类型的照明灯具在实际使用过程中，产品的稳定性和调光调色顺畅性受到一定程度的影响，影响使用者的使用体验。
并且，现有的线性恒流型驱动电路在实际生产和应用之中，为了满足其相应的使用需求，则需搭建相应的电路，例如为满足白光LED灯珠的驱动需求，则相应需至少搭建专用的驱动电路和为该驱动电路供电的专用供电电路，因而导致现有的线性恒流型驱动电路其电路繁琐复杂，并且灵活性低，难以满足市面上多方面的个性化需求，如当满足白光LED灯珠的驱动需求的驱动电路需添加无线控制模块时，难以直接在原有搭建的电路之中进行调整，而需要重新对电路进行排布搭建，导致相应的设计成本提高，且繁琐复杂的电路不利于对整体电路进行调试和安装，导致相应的测试和封装成本提高。
