通过将基板10的周侧均设置信号输入端和信号输出端，在对LED灯珠100进行安装时，可以对LED灯珠100对应安装环境进行任意旋转装配并可以根据实际产品需求任意选择基板10上的信号输入端和信号输出端对芯片20进行电路导通，从而优化LED灯珠100的电路布线和安装布置，保证LED灯珠100在不同需求环境下的使用装配。
此外，在本实施例中，如图4所示，基板10的每条侧边上的信号输入端和信号输出端均按照设定顺序排列，如可以按照第一信号输入端301、第二信号输入端302、第二信号输出端312、第三信号输入端303、第一信号输出端311、第三信号输出端313的顺序排布。并且基板的每条侧边上的信号输入端和信号输出端均以基板10的中心呈中心对称布置。
此种设置使得芯片20不管顺时针还是逆时针转动90°或者180°，基板10顶部的信号输入端和信号输出端均按照设定顺序排列，便于用户接线，避免接错，保证接线的准确和快捷。
在本申请的其他实施例中，芯片20还可以为白光芯片20和/或者单色芯片20。其中单色芯片20可以是R芯片21、G芯片22或B芯片23其中的一种。
以白光芯片20为例，该LED灯珠100的信号引脚组30包括与白光芯片 20电连接的正极信号输入端和负极信号输出端。本实施例的基板10为四边形结构，该基板10的四个侧边均设有正极信号输入端和负极信号输出端。
在本实施例中，LED灯珠100还包括信号线40，该信号线40包括与正极信号输入端连接的正极信号线和与负极信号输出端连接的负极信号线。在对LED灯珠100进行装配时，可以根据实际需求选择基板10任意侧边上的正极信号输入端和负极信号输出端进行电路导通。
在本实施例的其他示例中，芯片20包括白色芯片和单色芯片时，以单色芯片为R芯片21为例，基板10的周侧边均设有正极信号输入端、负极信号输出端、第一信号输入端301以及第一信号输出端311.
具体地，可以选择将正极信号线与负极信号线分别设置在基板10的两相对侧边上，或者将正极信号线与负极信号线分别设置在基板10的两相邻侧边上，或者将正极信号线与负极信号线设置在基板10的同一侧边上。
此外，本申请一实施例还提供一种摄影摄像灯，其包括上述的LED灯珠100和灯板，LED灯珠100设有多个，多个LED灯珠100在灯板上呈阵列布置。此种设置使得同一行相邻的LED灯珠100在进行旋转后，同一行的LED灯珠100仍然可以统一在该行的同一侧进行接线，从而便于灯板上的布线操作，优化线路的布置。
对于本申请的LED灯珠及摄影摄像灯，基板的至少两个侧边上均设置信号输入端和信号输出端，在对LED灯珠根据安装环境进行旋转装配时，其可以根据实际产品需求选择基板上合适的信号输入端和信号输出端对芯片进行电路导通，避免电路布线杂乱，简化LED灯珠的装配，从而优化LED灯珠的电路布线和安装布置，保证LED灯珠在不同需求环境下的使用装配。
