如图1-6所示的一种灯具，包括灯头1、前段灯体2、后段灯体3和灯具驱动器。其中，灯体为内部具有安装空腔的管状结构；灯头1连接在灯体的一端，用于和灯座相连以接入外接电源；灯具驱动器置于灯体内部的安装空腔中、并通过灯体上的限位结构安装在灯体上；灯体的外周设有第一镂空孔，灯具驱动器的电路板4具有自第一镂空孔向外露出的第一连接部410，第一连接部410与灯头1固定连接以实现灯具驱动器的电路板4和灯头1的电连接。
这种灯具，通过在灯体上设置限位结构，将灯具驱动器通过限位结构安装在的灯体的空腔中，并且灯具驱动器的电路板4的第一连接部410自第一镂空孔向外露出可以与灯头1直接固定连接以实现灯具驱动器的电路板1和灯头1的电连接；如此设计，灯头1与灯具驱动器的电路板1之间无需通过额外的电子线来实现电性连接，降低了材料成本，也避免了电子线因线材破皮，铜丝断裂等现象对灯具质量的影响；另外，灯头1和灯具驱动器的电路板1固定连接，灯头1无需采用胶水或外力打凹点的方式固定在灯体上，不会因胶水失效而影响连接可靠性，也不会因打凹点影响产品外观；而且，灯头1与灯具驱动器的电路板4直接固定相连的方式，配合牢固性好，灯头1无法进行正反转，不易发生松动。
在本实施例中，灯体包括相互配合的前段灯体2和后段灯体3。具体的，前段灯体2包括主体段210、位于主体段210一端用于和灯头1连接的前连接 段220、以及位于主体段210另一端用于和后段灯体3连接的后连接段230；主体段210、前连接段220和后连接段230为一体成型结构，主体段210的外径大于前连接段220和后连接段230的外径；主体段210和前连接段220之间设置有一对限位板240，限位板240之间形成有对电路板4的第一连接部410进行限位的限位槽。其中一个限位板240上开设有用于容置电路板4第一连接部410和灯头1之间焊接形成的焊接块的缺口241，灯头1的一端在缺口241焊接固定在电路板4第一连接部410上。
具体的，前连接段220的外周具有便于螺纹连接灯头1的外螺纹结构；前连接段220上对应一对限位挡板的外壁上形成有不具有外螺纹结构的缺口241槽221，前连接段220的侧壁和上设置有用于对电路板4进行限位的限位槽，内侧壁上一体成型有限位端面250，如此设置，使电路板4固定在灯体的安装空腔内，从而不会发生晃动或脱落。后段灯体3的外侧壁上一体成型有与后连接段230上的限位槽配合的限位柱310，以便对后段灯体3进行限位，避免后段灯体3安装在前段灯体2上时发生转动。
在本实施例中，灯具驱动器安装在灯体的安装腔内，灯具驱动器具体为LED驱动器，灯具驱动器的电路板4的一侧设有第一连接部410和第二连接部420；具体的，电路板4的第一连接部410、灯头1以及前段灯体2通过焊接固定连接，焊接形成的焊接块位于限位板240的缺口上，如此设计，既可以保持灯头1的完好，避免焊接时对灯头1造成损毁，同时不会影响灯具的美观。第二连接部420焊接固定在主体段210上靠近后段灯体3的端面上。
在本实施例中，灯头1焊接固定在前段灯体2上远离后段灯体3的一端，灯头1具体为螺口灯口，且螺纹连接在前段灯体2的前连接端的外螺纹结构上。
在本实施例中，发光件5设置在灯体外周，发光件5具体为LED发光体，LED发光体粘接固定在灯体的外周，LED发光体上设有多个LED灯珠。具体的，发光件5的一端焊接固定在主体段210上靠近后段灯体3的端面上，发光件5靠近主体段210的一端开设有可供第二连接部420插入的凹口510，且和电路 板4的第二连接部420在凹口510处焊接固定，以实现发光件5与电路板4的电连接，可以保证发光件5和电路板4之间的牢固性，避免除因长期使用导致发光件5和电路板4脱落。
在本实施例中，透光灯罩6固定在主体段210上，并置于发光件5的外周，以隔绝灰尘，水汽等杂物，同时起到保护LED灯珠作用。
综上所述，这种灯具，通过在灯体上设置限位结构，将灯具驱动器通过限位结构安装在的灯体的空腔中，并且灯具驱动器的电路板4的第一连接部410自第一镂空孔向外露出可以与灯头1直接固定连接以实现灯具驱动器的电路板1和灯头1的电连接；如此设计，灯头1与灯具驱动器的电路板1之间无需通过额外的电子线来实现电性连接，降低了材料成本，也避免了电子线因线材破皮，铜丝断裂等现象对灯具质量的影响；另外，灯头1和灯具驱动器的电路板1固定连接，灯头1无需采用胶水或外力打凹点的方式固定在灯体上，不会因胶水失效而影响连接可靠性，也不会因打凹点影响产品外观；而且，灯头1与灯具驱动器的电路板4直接固定相连的方式，配合牢固性好，灯头1无法进行正反转，不易发生松动。
另外，灯具驱动器的电路板4的第二连接部420与发光件5的凹口510之间无需通过额外的电子线来实现电性连接，降低了材料成本，也避免了电子线因线材破皮，铜丝断裂等现象对灯具质量的影响。
显然，上述实施例仅仅是为清楚地说明所作的举例，而并非对实施方式的限定。对于所属领域的普通技术人员来说，在上述说明的基础上还可以做出其它不同形式的变化或变动。这里无需也无法对所有的实施方式予以穷举。而由此所引伸出的显而易见的变化或变动仍处于本申请的保护范围之中。
