Description

LED灯一体式电连接结构
本发明涉及照明领域，特别涉及一种LED灯一体式电连接结构。
随着全球环保意识的提高，LED照明灯运用于室内照明领域得到快速的发展。传统的LED灯具结构主要包括灯头、设有驱动的驱动板、散热器、设有LED光源的光源板、灯泡壳等，其中，光源板、驱动板、灯头采用分体式，光源板与驱动板之间、驱动板与灯头之间分别采用导线焊线形成电连接，生产效率低，过程费时繁琐且不好定位安装，不利于自动化生产。目前已有改进的方案采用连接件实现灯头与驱动板、驱动板与光源板之间的电连接，但这些连接件往往结构复杂，组装工序较为复杂，制造成本高，且通常灯头与驱动板、驱动板与光源板之间需要分别采用不同的电连接件，使得制造工序多，不利于自动化生产。
有鉴于此，有必要提供一种结构简单、便于自动化组装的LED灯一体式电连接结构。
本发明采用的技术方案为： 一种LED灯一体式电连接结构，包括光源板、支撑板、灯头及至少一个导电件，该支撑板设置在该光源板及该灯头之间，所述导电件包括导电脚、固定部及插头，该固定部固定在该支撑板上，该导电脚与该灯头电连接，该插头与该光源板电连接从而将该灯头与该光源板电连接。
与现有技术相比，该LED灯一体式电连接结构设有导电件，其中还设有可以固定该导电件该支撑板，组装时，仅需将支撑板固定后而使得该导电件的导电脚与该灯头电连接、该导电件的插头与该光源板电连接，即可将该灯头与该光源板电连接，由于该LED灯一体式电连接结构组装时无需将光源板、驱动板及灯头依次电连接，省略了中间分别将光源板与驱动板、驱动板与灯头电连接的安装步骤，安装简便，且无需复杂的结构，制造工序简单，具有结构简单、便于自动化组装的优点。
