请参照图1，图1为本发明实施例提供的一种光控LED灯丝灯300的结构示意图。所述光控LED灯丝灯300包括玻璃外壳310、螺旋灯头350、灯柱330、排气管340、灯丝320以及光控LED灯丝灯驱动系统200，所述灯丝320包括所述多个LED灯丝灯光源210，所述玻璃外壳310与所述螺旋灯头350固定连接，所述灯柱330设置在所述螺旋灯头350上，所述灯柱330两端设有金属插接端子，所述金属插接端子与所述光控LED灯丝灯驱动电源100电连接，所述灯丝320的两端插接在所述金属插接端子上，所述排气管340设置在所述玻璃外壳310内。
其中，所述灯丝320是由所述多个LED灯丝灯光源210组成的可拉伸长度的柔性LED灯丝，所述多个LED灯丝灯光源210为所述光控LED灯丝灯300的发光光源，该发光光源为LED，即发光二极管。
另外，所述光控LED灯丝灯300的具体结构为本领域技术人员所公知的，因此不再过多赘述。
请参照图2，图2为本发明实施例提供的一种光控LED灯丝灯驱动系统200的结构框图，所述光控LED灯丝灯驱动系统200包括多个LED灯丝灯光源210以及光控LED灯丝灯驱动电源100，所述光控LED灯丝灯驱动电源100与所述多个LED灯丝灯光源210耦合。
所述光控LED灯丝灯驱动电源100包括整流保护模块110、光控模块120及驱动模块130，所述整流保护模块110与所述光控模块120耦合，所述光控模块120与所述驱动模块130耦合，所述驱动模块130与所述多个LED灯丝灯光源210耦合。
其中，所述光控模块120用于根据外部光信号的变化来控制所述驱动模块130， 以使所述驱动模块130驱动所述多个LED灯丝灯光源210发光。该光控模块120将外部环境的光信号转换成电压值，从而根据电压值与预先存储的电压值进行比较，若该电压值大于预先存储的电压值，则不输出控制信号，从而所述驱动模块130无法驱动所述多个LED灯丝灯光源210发光；若该电压值小于或等于预先存储的电压值，则输出控制信号，从而控制所述驱动模块130驱动所述多个LED灯丝灯光源210发光。
请参照图3，图3为本发明实施例提供的一种光控LED灯丝灯驱动电源100的结构框图。作为一种实施方式，所述光控模块120可以包括控制模块124和光电转换模块122，所述控制模块124与所述光电转换模块122耦合，所述控制模块124还分别与所述整流保护模块110、驱动模块130耦合。
其中，所述光电转换模块122用于将外部环境光信号转换成电信号，在本实施例中，所述光电转换模块122可以为光敏二极管，该光敏二极管是一种能够将光根据使用方式，转换成电流信号或者电压信号的光探测器。光敏二极管的管芯常使用一个具有光敏特征的PN结，该PN结对光的变化非常敏感，具有单向导电性，而且光强不同的时候对应的电学特性也会不一样，因此，可以利用光照强弱来改变电路中的电流大小。
所述控制模块124用于接收所述光电转换模块122传输的电信号，该电信号可以为电压信号或电流信号，在本实施例中，为了方便描述，该电信号为电压信号，并且通过比较某一时刻接收到的电压值与预先存储的电压阈值，从而向所述驱动模块130输出控制信号。在本实施例中，所述控制模块124可以为单片机，该单片机可以是8051系列单片机或STM32系列单片机，该STM32系列单片机具有高性能内核、低功耗、高集成度以及结构简单等优点，并具有高速的数据处理能力。
另外，控制模块124向所述驱动模块130输出的控制信号可以为一个电平信号，例如高电平或低电平。可选地，高电平可以为3.3V，低电平可以为0V。
当LED灯丝灯所处环境的光亮强度较强时，不需要光控LED灯丝灯300发光，当LED灯丝灯所处环境的光亮强度较弱时，需要光控LED灯丝灯300发光。可选地，可以通过以下方式来控制光控LED灯丝灯300的发光状态。
光电转换模块122将接收到的光信号转换为相对应的电压信号，其中，光信号可以是所述LED灯丝灯所处环境的光照强度。光电转换模块122根据相关的计算公 式将光电转换模块122接收到的光信号转换成的电压值，所述控制模块124将接收到的电压值与预先存储的电压值进行比较，在本实施例中，可选地，该预先存储的电压阈值为环境的光照强度70LUX时所对应的电压值，若所述LED灯丝灯所处环境的光照强度大于70LUX，控制模块124接收到的电压值将会比预先存储的电压阈值大，控制模块124则向驱动模块130输出低电平，以使驱动模块130无法驱动多个LED灯丝灯光源210发光。若所述LED灯丝灯所处环境的光照强度小于或等于70LUX时，控制模块124接收到的电压值将会小于或等于预先存储的电压阈值，控制模块124则向驱动模块130输出高电平，以使驱动模块130驱动多个LED灯丝灯光源210发光。
作为一种可选的实施方式，所述控制模块124可以使用电压比较器来进行电压值的比较，将通过光信号转换得到的电压值与预设的电压阈值进行比较，也就是所述光电转换模块122传输给该电压比较器的电压值与预设的电压阈值进行比较，这里的预设的电压值也可以为环境照度为70LUX时，所述光电转换模块122转换的相应的电压值。若该电压比较器输入的电压值小于或等于预设的电压值时，则该电压比较器输出高电平以控制所述驱动模块130驱动所述多个LED灯丝灯光源210发光；若该电压比较器输入的电压值大于预设的电压值时，则该电压比较器输出低电平，从而驱动模块130无法驱动所述多个LED灯丝灯光源210发光。
所述整流保护模块110用于将所述外部电源输入的220V交流电整流为直流电。所述整流保护模块110包括整流电路112与保护电路114，所述整流电路112的输入端与外部电源耦合，所述整流电路112的输出端与所述保护电路114耦合，所述保护电路114与所述光控模块120耦合，可选地，所述保护电路114分别与控制模块124及光电转换模块122耦合。
