具体实施方式
在下面的详细描述中，提出了许多具体细节，以便于对本实用新型的全面理解；但是，对于本领域技术人员来说很明显的是，本实用新型可以在不需要这些具体细节中的一些细节的情况下实施；下面对实施例的描述仅仅是为了通过示出本实用新型的示例来提供对本实用新型的更好地理解。
下面将结合附图，对本实用新型实施例的技术方案进行描述。
本实施例涉及一种LED面板灯，包括：面板和发光组件，所述面板包括第一区域1和多个第二区域2，所述第二区域2围绕所述第一区域1的周向外侧设置，所述发光组件安装在所述面板的与所述第一区域1对应的位置处。其中，第一区域1为出光面，是LED面板灯光线射出区域部分；第二区域2作用结构面，面板灯面板除出光面的部分均作为结构面。出光面和结构面组成与常规LED面板灯一致的外观尺寸。在同一个面板中，结构面可以有多个，出光面也可以有多个，共同组成面板灯的完整面板。
在图1至图10所示的四个实施例中，面板可以是分体式的拼接结构(例如第一、第二、第四实施例)，也可以是一体的整套板(第三实施例)。但是，无论哪种情况，本发明中的面板中部均设置有一个第一区域1，其上部安装发光组件，光线可从该第一区域中向外射出。
在上述各实施例中，与现有技术相比，面板的外部整体尺寸是固定不变的，可以调节第一区域和第二区域的大小，从而减小了发光组件所在第一区域及发光组件本身的面积，且发光组件的光电参数不变，从而在保证光电参数的情况下，使本申请达到了与常规现有技术中的面板灯外观尺寸一致的目的，降低了成本，可根据应用场合的不同，给予面板灯不同的安装配件进行安装使用。
在第一和第二、第四实施例中，优选地，所述面板包括用于形成所述第一区域1的第一板3以及用于形成所述第二区域2的第二板4，所述第一板3及多个所述第二板4拼接成所述面板。
优选地，所述第一板3为扩散板，所述第二板4为金属板或塑胶板。
在第三实施例中，优选地，所述面板采用一块完整且无拼接的第三板5制成。优选地，所述第三板5为扩散板。在此实施例中，如图6和图8所示，第三板5也可被划分为由图中虚线所分隔开的第一区域和第二区域，其中，第一区域用作出光面，第二区域用作结构面。由于采用了这种结构，缩小了出光面的面积，因而降低了成本。
在第一至第三实施例中，优选地，所述发光组件包括导光板6(例如玻璃等)、LED灯条7和反光板8，所述反光板8位于所述导光板6的远离所述第一区域1的一侧，所述LED灯条7设置在所述导光板6的侧面。
优选地，所述反光板8的远离所述导光板6的一侧通过海绵胶9粘接有盖板10。
优选地，所述盖板10为金属板或塑胶板。
优选地，所述第一板3的四周安装有型材11，所述第二板4的边缘与所述型材11边缘卡接。
优选地，所述LED面板灯包括由型材11制成的底框12，所述底框12上形成多个分隔的出光面和结构面，所述第一板3安装于所述出光面处，所述第二板4安装于所述结构面处。
在第四实施例中，发光组件位于灯具的中央部位，该发光组件的周边均为结构面。
以上实施例仅用以说明本实用新型的技术方案，而非对实用新型的保护范围进行限制，显然，所描述的实施例仅仅是本实用新型部分实施例，而不是全部实施例；基于这些实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本实用新型所要保护的范围。
尽管参照上述实施例对本实用新型进行了详细的说明，本领域普通技术人员依然可以在不冲突的情况下，不作出创造性劳动对本实用新型各实施例中的特征根据情况相互组合、增删或作其他调整，从而得到不同的、本质未脱离本实用新型的构思的其他技术方案，这些技术方案也同样属于本实用新型所要保护的范围。
