实施例
请参阅图1，本实施例提供了一种LED灯泡1，可以应用于电器设备。该电器设备可以为照明设备，例如，可以为室内照明灯具、户外照明灯具、汽车灯具等。该电器设备包 括载体装置及上述的LED灯泡1，其中，LED灯泡1安装于载体装置上。采用这种LED灯泡1，既能够保证性能，又能够降低成本。
该LED灯泡1包括灯头10、与灯头10连接的外泡壳20、设置于外泡壳20内的支撑件30以及设置于支撑件30上的LED发光组件40和非线性正电阻结构件50。其中，灯头10安装于载体装置上。非线性正电阻结构件50与LED发光组件40串联，被构造为使LED发光组件40实现稳流。
由于非线性正电阻结构件50具有非线性正电阻特性，在LED灯泡1在接通电源后，非线性正电阻结构件50能够在很短时间内电阻上升至一较大值，并且在持续通电时，保持在该较大值，从而能够使LED发光组件40达到分压稳流的作用。这样，省去了IC电路的电子元器件，减少了该电子元器件的材料及能耗，降低了成本，保证了LED灯泡1的性能。
可选地，本实施例中，外泡壳内充有惰性散热气体，用于对LED发光组件40进行散热。其中，惰性散热气体可以包括氦气、氢气、氮气或其任意组合混合气体。也就是说，惰性散热气体可以包括氦气、氢气或氮气，也可以包括氦气、氢气及氮气的任意两者或三者组合的混合气体。
进一步地，非线性正电阻结构件50包括白炽灯泡，白炽灯泡与LED发光组件40串联。本实施例中，白炽灯泡包括白炽灯壳(图未示)和设置于白炽灯壳内的钨丝(图未示)，白炽灯壳设置于支撑件30上，钨丝与LED发光组件40串联。
可选地，白炽灯壳内设置为真空或者充有保护气体。其中，保护气体可以包括氪气、氮气、氩气或其任意组合混合气体。也就是说，保护气体可以包括氪气、氮气或氩气，也可以包括氪气、氮气及氩气的任意两者或三者组合的混合气体。
白炽灯泡为非线性正电阻特性，接通电源后，白炽灯泡在很短时间内，如1ms，即能够在很短时间内电阻上升至一较大值，例如可将原来只有10Ω的电阻升到2KΩ，在持续通电升温时，白炽灯泡保持该较大值，例如2KΩ左右，变化不大，即可达到分压恒流的作用。从而省去了IC电路的电子元器件，减少了该电子元器件的材料及能耗，内置的白炽灯泡成本低，降低了成本。
另外，使用白炽灯泡，白炽灯泡的发光增加了整灯光通量，即提高了光效性能。同时白炽灯泡能够发出红外光和可见光。白炽灯泡与LED发光组件40共同发光，可将电能转化为可见光和红外光，可见光可增高LED灯泡1整灯的光通量，而红外光则可对人体有保健作用，从而大大提高了该LED灯泡1的光效，光效接近100％。并且，白炽灯泡发出的光是全光谱，这也弥补了LED灯非全光谱的缺陷。这样，使宽光谱的LED灯泡1继承了传统白炽灯的健康照明以及传统LED灯的高效节能的特点，即达到健康、节能的效益。
当然，在本公开的其他实施例中，非线性正电阻结构件50也可以采用其他具有非线性 正电阻特性的电阻。

需要说明的是，整流电路60可以与LED发光组件40为一体化设置；也可以是整流电路60设置于LED发光组件40外部，即整流电路60与LED发光组件40为相互独立的两部分，整流电路60分别与非线性正电阻结构件50及LED发光组件40电连接。整流电路60与LED发光组件40一体化设置是指整流电路60由发光件41按照整流桥式排布形成或者由发光件41与其他电子器件串联形成且发光件41与该电子器件集成于一体。
本实施例中，整流电路60与LED发光组件40为一体化设置。整流电路60可以采用全波整流桥。整流电路60与LED发光组件40设置于外泡壳20内且固定于支撑件30上。LED发光组件40包括至少四根发光件41，整流电路60由至少四根发光件41按照全波整流桥式排布依次电连接形成。本实施例中，发光件41为四根，且均为LED灯丝条，采用的是发光二极管。整流电路60由四根发光件41按照全波整流桥式排布依次电连接形成。
需要说明的是，发光件41也可以多于四根，只要其中四根发光件41能够按照全波整流桥式排布依次电连接形成整流电路60即可。
另外，整流电路60也可以采用半波整流桥(图未示)。可选地，LED发光组件40包括至少两根发光件41，整流电路60由至少两根发光件41按照半波整流桥式排布依次电连接形成。其中，发光件41可以为两根，且均为LED灯丝条，采用的是发光二极管。整流电路60由两根发光件41按照半波整流桥式排布依次电连接形成。需要说明的是，发光件41也可以多于两根，只要其中两根发光件41能够按照半波整流桥式排布依次电连接形成整流电路60即可。
另外，请参阅图3，在本公开的其他实施例中，整流电路60也可以由发光件41与其他电子器件串联形成且发光件41与该电子器件集成于一体。可选地，LED发光组件40包括发光件41和防击穿电器件(图未示)，发光件41与防击穿电器件串联形成整流电路60，发光件41与防击穿电器件集成于一体。其中，发光件41为LED灯丝条，采用的是发光二极管，防击穿电器件为二极管。也就是说，LED发光组件40自带整流电路60，这种LED发光组件40可以称为AC LED，即交流LED。
请参阅图4，在本公开的一实施例中，在本实施例的基础上，LED灯泡1还可以包括第一电容70，第一电容70与整流电路60及非线性正电阻结构件50并联。这样，能够减少LED灯泡1发生频闪现象。
请结合参阅图5和图6，在本公开的另一实施例中，整流电路60设置于LED发光组件40外部，整流电路60分别与非线性正电阻结构件50及LED发光组件40电连接。这样的LED发光组件40可以称为DC LED，即直流LED。该整流电路60设置于灯头10内，可以为LED发光组件40供电。应当理解的是，独立于LED发光组件40外部的整流电路60可以是全波整流桥(请参阅图7)，也可以是半波整流桥(图未示)等。
请参阅图8，进一步地，LED灯泡1还可以包括第二电容80，第二电容80与整流电路60并联。这样，能够减少LED灯泡1发生频闪现象。
请继续参阅图1，进一步地，本公开实施例中，外泡壳20内可以设置有添加有长余辉放电物质的荧光粉。这样，能够减少LED灯泡1发生频闪现象。
另外，本实施例中，灯头10、支撑件30及外泡壳20采用传统封装工艺。其中，支撑件30包括芯柱，芯柱具有相对设置第一端部31及第二端部32，LED发光组件40和非线性正电阻结构件50安装于第一端部31，第二端部32伸入灯头10内。需要说明的是，在本公开的其他实施例中，支撑件30也可以不采用芯柱，而采用支架结构。
本实施例中，芯柱内设置有排气管33，第一端部31上设置有排气孔34，排气孔34与排气管33连通，排气管33远离排气孔34的一端由第二端部32穿出。
综上所述，本公开提供的LED灯泡1及电器设备采用非线性正电阻结构件50与LED发光组件40串联，由于非线性正电阻结构件50具有非线性正电阻特性，在LED灯泡1在接通电源后，非线性正电阻结构件50能够在很短时间内电阻上升至一较大值，并且在持续通电时，保持在该较大值，从而能够使LED发光组件40达到分压稳流的作用。这样，省去了IC电路的电子元器件，减少了该电子元器件的材料及能耗，降低了成本，保证了LED灯泡1的性能。
以上所述仅为本公开的优选实施例而已，并不用于限制本公开，对于本领域的技术人员来说，本公开可以有各种更改和变化。凡在本公开的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本公开的保护范围之内。
工业实用性
本公开提供的LED灯泡1及电器设备能够使LED发光组件40达到稳流的作用，省去了IC电路的电子元器件，减少了该电子元器件的材料及能耗，降低了成本，保证了LED灯泡1的性能。
