下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅是本发明的一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其它实施例，都属于本发明保护的范围。
请参见图3，图3是本发明的灯条组件的第一实施例的结构示意图。
如图3所示，本实施例的灯条组件30主要包括光源301、电路板302和连接器303。
其中，光源301为LED灯，位于电路板302的一侧，这种LED灯的数目不限，可以根据具体的需要而定。电路板302包括第一支撑部3021和相对于第一支撑部3021向电路板302的另一侧弯折的弯折部3022。弯折部3022位于电路板302的端部，其包括第二支撑部3024和连接部3025。其中，连接部3025用于连接第一支撑部3021和第二支撑部3024，第二支撑部3024与第一支撑部3021平行设置，且连接部3025分别与第一支撑部3021、第二支撑部3024垂直设置。光源301位于第一支撑部3021上，连接器303位于第二支撑部3024上，并且光源301与连接器303位于电路板302的同一侧，连接器303与光源301之间电连接。
其中，光源301具有平行且远离第一支撑部3021的第一表面311，连接器303具有平行且远离第二支撑部3024的第二表面313。如图4所示，光源301以及连接器303满足以下关系：
连接器303的第二表面313所在的平面（A）不高于光源301的第一表面311所在的平面（B）。
在本实施方式中，优选为第一表面311和第二表面313位于同一平面上。另外，在本实施例中，第一支撑部3021上还设有通孔304，在下文描述的本发明的背光模组的实施例中，将进一步详述通孔304的作用。
请参见图5，图5是本发明的灯条组件的第二实施例的结构示意图。如图5所示，本实例的灯条组件50与第一实施例的灯条组件30的不同之处在于：包含第二支撑部5024和连接部5025的弯折部5022向电路板502上设有光源501的一侧弯折，而连接器503位于弯折部5022的第二支撑部5024上，使得连接器503与光源501位于电路板502的相对两侧。
其中，光源501具有平行且远离第一支撑部5021的第一表面511，第二支撑部5024具有背向连接器503的底面5026。如图6所示，光源501和第二支撑部5024满足以下关系：
第二支撑部5024的底面5026所在的平面(平面C)不高于光源501的第一表面511所在的平面(平面D)。
在本实施方式中，优选为光源501的第一表面511和第二支撑部5024的底面5026位于同一平面上。
请参阅图7，图7是包含图3所示灯条组件的本发明的背光模组的第一实施例的结构示意图。
如图7所示，本实施例的背光模组300主要包括导光板705和图3所示的灯条组件30，其中的光源301面向导光板705设置，本实施例中，灯条组件30的结构在前文中有详细描述，在此不在赘述。
背光模组300进一步包括固定件706，固定件706包含一固定柱707，第一支撑部3021通过通孔304套在固定柱707上，其中固定圆柱707穿过第一支撑部3021上的通孔304(参见图3所示)并与导光板705贴合在一起，以实现灯条组件30与导光板705的相对固定，使得经光源301发出的光可稳定地通过导光板705传导，以继续后续照明显示工作。
请参阅图4，由于连接器303的第二表面313所在的平面A不高于光源301的第一表面311所在的平面B，因此在本发明的背光模组300中，连接器303的第二表面313不再突出于光源301的第一表面311和导光板705之间，避免了切割导光板705导致的成本增加，降低了背光模组300漏光的风险。
如图7所示，背光模组300进一步括胶框708，由固定件706连接在一起的灯条组件30及导光板705置于该胶框708中。本实施例中，胶框708用于保护设置于其内部的各种组件。
请参阅图8，图8是包含图5所示的灯条组件的本发明的背光模组的第二实施例的结构示意图。
如图8所示，本实施例的背光模组500与第一实施例的背光模组300的主要不同之处在于：弯折部5022向电路板502上设有光源501的一侧弯折，而连接器503位于弯折部5022的第二支撑部5024上，使得连接器503与光源501位于电路板502的相对两侧。
请配合参阅图6所示，由于第二支撑部5024的底面5026所在的平面C不高于光源501的第一表面511所在的平面D，因此背光模组500在组合时同样无需在连接器503对应处切割导光板705避让，由此降低生产成本，降低背光模组500漏光的风险。
通过上述方式，本发明的灯条组件和背光模组，通过在电路板上设置弯折部，并将连接器设置于弯折部上，避免了组装时在对应连接器处对导光板裁切，降低了背光模组的漏光风险，有效降低了生产成本，提高了背光模组的可靠性。
以上所述仅为本发明的实施例，并非因此限制本发明的专利范围，凡是利用本发明说明书及附图内容所作的等效结构或等效流程变换，或直接或间接运用在其他相关的技术领域，均同理包括在本发明的专利保护范围内。
