所述安装件2与所述灯头1相连接，其内部设有容置腔，所述容置腔用于容置芯柱3的下半部、拨码开关5等，保证灯丝灯内部具有足够的空间安装上述部件。
为了保证所述LED灯丝4能够正常工作，所述驱动电源7设于所述容置腔内部，其与所述拨码开关5及LED灯丝4通过导线或其他电连接件实现电连接。
所述芯柱3用于安装LED灯丝4，并实现所述驱动电源7及于所述LED灯丝4之间的电连接，其包括芯柱本体31和贯穿所述芯柱本体31的金属导丝32，所述芯柱本体31与所述外壳6密封连接，构成密闭的腔体，所述LED灯丝4位于该腔体内部，用以保护所述LED灯丝4，提高灯丝灯的使用寿命。所述金属导丝32贯穿所述芯柱本体31，其一端与所述驱动电源7相连接，另一端与所述LED灯丝4相连接，实现了所述LED灯丝4与驱动电源7之间的电连接。
所述LED灯丝4包括基板41、设于所述基板41端部的第一引脚42、设于所述基板41另一端的第二引脚43、设于所述基板41上的第一LED芯片组44以及设于所述基板41上的第二LED芯片组45，所述基板41用于组装所述第一引脚42、第二引脚43、第一LED芯片组44以及第二LED芯片组45，便于将所述LED灯丝4组装成一个整体结构，所述第一引脚42设于所述基板41的端部，其与所述金属导丝32电连接，从而实现了LED灯丝4的电连接，所述第二引脚43设于所述基板41的另一端，其与所述第一引脚42分别构成LED灯丝4的正负极。
所述第一LED芯片组44设于所述基板上，用于实现照明，其包括若干相互连接的第一LED芯片和覆盖所有所述第一LED芯片的第一荧光胶，且所述第一LED芯片的正极通过金属线与所述第一引脚42相连接，所述第一LED芯片的负极通过金属线与所述第二引脚43相连接，从而实现了第一LED芯片组44的安装。

需要说明的是，如图4所示，所述拨码开关为双刀双掷开关，由于所述拨码开关5与所述驱动电源7相连接，当其接通驱动电源7的正极与第一引脚42时，会同时接通驱动电源7的负极与第二引脚43，由于第一LED芯片组44的正极与第一引脚42相连接，负极与第二引脚43相连，故第一LED芯片组44正向，从而被点亮。第二LED芯片组45的负极与第一引脚42相连接，正极与第二引脚连接，故第二LED芯片组45反向，从而不被点亮。相应的，当所述拨码开关5接通驱动电源7的负极与第一引脚42时，会同时接通驱动电源7的正极与第二引脚43，由于第二LED芯片的负极与第一引脚42相连接，正极与第二引脚相连接，故所述第二LED芯片组45正向，从而被被点亮，所述第一LED芯片组44反向不被点亮。
本发明通过简单的拨码开关5实现了不同色温的切换，结构简单，且消费者实用方便。
所述外壳6与所述芯柱密封连接，构成密闭的腔体，为了提高散热效率，所述腔体内部还可以填充有散热气体，所述散热气体为氦气或氦气与氧气的混合气，保护LED灯丝的使用寿命。

所述开关检测电路52’接受外部的信号，并用于控制所述第一电子开关组与第二电子开关组的开合，其型号为SM2212EK。
工作时，当所述开关检测电路52’开启第一电子开关组时，所述第二电子开关组关闭，所述驱动电源的电信号依次经过开关S1、第一LED芯片组、开关S4，形成一个回路，即可点亮第一LED芯片组。
当所述开关检测电路52’开启第二电子开关组时，所述第一电子开关组关闭，所述驱动电源的电信号依次经过开关S3、第二LED芯片组、开关S2，形成一个回路，即可点亮第二LED芯片组。
所述控制开关5’接受外部的开关信号，开启第一电子开关组，点亮第一LED芯片组，或者开启第二电子开关组，点亮第二LED芯片组，从而实现LED灯丝的色温的智能切换，使用方便。
本发明提供的可变色温的LED灯丝灯，LED灯丝为一个整体结构，通过控制开关5’的设置，第一引脚42和第二引脚43可以根据实际需要切换连接到所述驱动电源输出端的正极或负极，从而实现不同色温的智能切换，用户使用方便。
