具体地，所述基板110可以采用玻纤板(FR4)、玻璃、陶瓷、蓝宝石等全透明或者半透明的材料，也可以使用铜铝等不透明材料，在此不作限定。应该注意的是，在本实施例中以条形基板为例，基板材料厚度和形状可以根据实际需求设定，在此不作限定。所述LED倒装晶片与第一连接端子130、所述第二连接端子140均通过导电线路连接。所述导电线路用于连接所述LED倒装晶片和其他元器件。所述导电线路的材质通常为敷铜，也可以采用其他导电金属，在此不作限定。
可以理解的是，灯条100可以包括至少两个连接端子，本申请实施例以两个连接端子为例，连接端子的数量可以根据实际需求设定，在此不作限定。
为了使LED灯能够直接接入交流电，在一种可选的实施方式中，所述发光线路120可以包括第一LED倒装晶片125、第二LED倒装晶片126、第三LED倒装晶片127、第四LED倒装晶片128和所述LED倒装晶片组，所述LED倒装晶片组包括第五LED倒装晶片129。
所述第一LED倒装晶片125的负极可以连接至所述第二LED倒装晶片126的负极，所述第二LED倒装晶片126的正极可以连接至所述第三LED倒装晶片127的负极，所述第三LED倒装晶片127的正极可以连接至所述第四LED倒装晶片128的正极，所述第四LED倒装晶片128的负极可以连接至所述第一LED倒装晶片125的正极，所述第一LED倒装晶片125的正极与所述第四LED倒装晶片128的负极之间的第一节点可以连接至所述第一连接端子130和所述第二连接端子140中的一者，所述第一LED倒装晶片125的负极与所述第二LED倒装晶片126的负极之间的第二节点可以连接至所述第五LED倒装晶片129的正极，所述第五LED倒装晶片129的负极可以连接至所述第三LED倒装晶片127的正极与所述第四LED倒装晶片128的正极之间的第三节点，所述第二LED倒装晶片126的正极与所述第三LED倒装晶片127的负极之间的第四节点可以连接至所述第一连接端子 130和所述第二连接端子140中的另一者。
在本实施例中，以所述LED倒装晶片组可以包括第五LED倒装晶片129为例，可以理解的是，所述LED倒装晶片组可以包括至少一颗LED倒装晶片，所述LED倒装晶片组包括的LED倒装晶片的数量可以根据实际需求设定，在此不作限定。
可选地，所述第一LED倒装晶片125、第二LED倒装晶片126、第三LED倒装晶片127和第四LED倒装晶片128组成了一个整流桥堆。请参照图2，图2示出了本申请实施例提供的灯条的发光线路的原理图。交流电压正半周的运行原理为：交流电源170产生电流，电流依次通过第一LED倒装晶片125、第五LED倒装晶片129、第三LED倒装晶片127，流回交流电源170。交流电压负半周的运行原理为：交流电源170产生电流，电流依次通过第二LED倒装晶片126、第五LED倒装晶片129、第四LED倒装晶片128，流回交流电源170。
在本实施例中，整流桥堆利用LED倒装晶片正向导通反向截止的半导体特性，将输入交流LED柔性灯丝的交流电转换为直流电。结构简单，在交流电输入端和灯条之间不需要增加驱动电源，降低LED灯的整体成本，同时，由于没有驱动电源，减少了发光装置上驱动电源的空间位置，底座尺寸和形状都不受驱动电源的影响。
可以理解的是，本实施例是以四颗LED倒装晶片组成一个整流桥堆为例，整流桥堆的LED倒装晶片的数量以及各LED倒装晶片之间的串并联方式不限，只要能组成满足电性要求的整流桥堆即可。
为了提高了灯条的可靠性和散热性，在一种可选的实施方式中，所述LED倒装晶片的正极和负极可以分别通过导电锡膏(图未示)与导电线路连接。所述导电锡膏可以用于连接元器件。导电锡膏连接LED倒装晶片和导电线路，提高了灯条的可靠性和散热性。
请参照图3，图3示出了本申请实施例提供的另一种灯条的结构示意图。
在上述实施例的基础上，为了便于固定所述LED灯条100，所述灯条100还可以包括卡口160，所述卡口可以与所述连接端子设置在所述基板110的同一端。所述卡口160可以用于连接LED灯的底座。
由于实际输入交流电压存在一定波动，且LED灯条点亮所需要的实际电压也有一些波动，为了避免LED灯条在电压变化的冲击中受损，提高LED灯整体的可靠性，在一种可选的实施方式中，所述发光线路120还可以包括限流电阻150，所述限流电阻150可以设置在所述第一节点与所述第一连接端子130和所述第二连接端子140中的一者之间，或可以设置在所述第四节点与所述第一连接端子130和所述第二连接端子140中的另一者之间，所述限流电阻150可以用于限制所述发光线路120的电流。通过连接一个阻值合适的限流电阻，分担多余电压，同时限制通过的电流，以提高LED灯整体的可靠性。
可以理解的是，如果单独使用限流电阻的线路稳定性得不到保证时，可以在发光线路120中加入一些辅助器件，如电容、电感等。
为了提高灯条100的使用寿命，请参照图4，图4示出了图3中的灯条沿AA方向的剖视图，所述基板110可以包括第一部分111和第二部分112，所述发光线路120设置于所述第一部分111，所述连接端子可以设置于所述第二部分112，所述第一部分111的表面可以设置有荧光保护胶180，所述发光线路120可以位于所述荧光保护胶180和所述第一部分111的表面之间。所述荧光保护胶可以用于保护LED倒装晶片等元器件。
为了便于调节所述发光线路120的发光颜色，在一种可选的实施方式中，所述荧光保护胶180可以包括保护胶和荧光粉，所述荧光保护胶180可以用于调节所述发光线路120的发光颜色。可以理解的是，在不需要调节LED倒装晶片发光颜色时，可以不在所述荧光保护胶180内加入荧光粉。

请参照图5，图5示出了本申请实施例提供的LED灯的结构示意图。本申请实施例还提供了一种LED灯1000，所述LED灯1000可以包括如上述图1至图4所示的的灯条100、泡壳200和底座300。所述灯条100可以设置于所述泡壳200与所述底座300组成的腔体内。所述泡壳可以用于保护灯条100，材质、透光度、形状和大小可以根据实际需求选择，在此不作限定。

本申请实施例提供的发光装置，与上述图1至图4提供的灯条100具有相同的技术特征，所以也能解决相同的技术问题，达到相同的技术效果，在此不再赘述。
在这里示出和描述的所有示例中，任何具体值应被解释为仅仅是示例性的，而不是作为限制，因此，示例性实施例的其他示例可以具有不同的值。
应注意到：相似的标号和字母在下面的附图中表示类似项，因此，一旦某一项在一个附图中被定义，则在随后的附图中不需要对其进行进一步定义和解释。
以上所述实施例仅表达了本申请的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对本申请范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本申请构思的前提下，还可以做出若干变形和改进，这些都属于本申请的保护范围。
