本发明涉及LED照明领域，尤其涉及一种LED直发光面板灯。
背景技术
现有LED直发光面板灯是由金属外壳、LED光源、灯板、透镜、扩散罩、边框和螺丝等结构件组装成的壳体，由感应器、线材和LED驱动电源等电子元器件组成的智能控制系统，来实现LED灯珠的照明功能和节能效果，以使它能大面积的替代了原来以荧光灯管为光源的灯盘，被广泛的应用在写字楼、办公室、商场和厨卫间等场所。
现有的LED直发光面板灯，是需要将贴有LED灯珠和透镜的灯板，用螺丝固定在金属外壳底平面上；扩散罩是通过边框用螺丝固定在金属外壳的上(LED灯珠的前面)；控制系统可以内置在灯具壳体内，也可以放在壳体的外部；LED灯珠通电发光后，能通过扩散板内部的微结构和扩散散剂，调整LED发出的光线、使光线在不同方向的产生折射和漫反射，从而改变光的行进路线，以减少扩散板出光面的防光或亮斑等。
但是现有的LED直发光面板灯存在以下缺点：
(1)、生产过程复杂：LED灯珠上的透镜用胶水固定在灯板上(铝基板或PCB)，透镜的焦点需要同LED芯片重合，位置偏移时，会产生分色或出光角度变小，定位困难；灯板需要用多颗螺丝固定在外壳上，组装耗时；控制系统同LED灯板连接需要采用连接头或焊接，在运输和使用过程中，因振动或焊接等原因，有接触不良的风险存在，很可能使正常使用的灯具出现闪烁和不亮的现象；压扩散罩的边框也需要通过多颗螺丝固定在外壳上，同样会让组装费时，不利于自动化大批量生产；
(2)、维修不方便：当LED光珠或内置控制系统出现故障，LED灯珠不亮时，需要更换LED灯板或控制系统时，没有专业的知识和专业的工具，有很大的可能会使维修失败：首先需要切断电源，从天花板上取出灯具，其次需要用专业的工具拆卸边框上的螺丝，用电络铁焊掉灯板与控制系统之间的连接线，再次用专业工具拆卸固定灯板的螺丝，然后更换新灯板，最后，再用电络铁焊接灯板与控制系统之间连接线，用专业工具按前面的工序顺序反向操作一次，一般的消费者是难以完成维修工作的；
(3)、耐候性差：由于塑料扩散板是由边框压在壳体上，导致扩散板在热膨冷缩的情况下，没有伸展的空间，将会出现尺寸变形弯曲或断裂的情况。

具体实施方式
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，所描述的实施例仅仅是本发明一部分实施例，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，都属于本发明保护的范围。
本发明提供了一种LED直发光面板灯，包括灯体和控制系统；
所述灯体包括带有若干个微结构柔性自锁器A面的金属灯具外壳、N个FFC灯板、带有若干个微结构柔性自锁器B面的扩散板以及N个永磁压条；所述N个永磁压条通过与所述金属灯具外壳的强吸引力将所述N个FFC灯板固定在所述金属灯具外壳的凹形底平面内，所述控制系统与所述N个FFC灯板连接；所述扩散板与所述金属灯具外壳，通过柔性自锁器的A面的微结构和B面的微结构的相互紧锁而相连接。
在本实施例中，通过减少光源板用螺丝固定在灯具壳体的工序，从而减少了电源输出线焊接在灯板上的工序，以达到节省人力物力成本的目的。
更进一步的，通过减少扩散板通过边框用螺丝固定在灯具壳体的工序，能够使得本发明提供的面板灯的整个生产过程均可采用自动化机械不分昼夜的大批量生产，进一步的节省了大量的人力物力成本。
请参见图1和图3，在本发明实施例中，所述微结构柔性自锁器A面上设有多个O型或n型的带状物，所述微结构柔性自锁器B面上设有多个倒L型的带状物；所述微结构柔性自锁器A面和B面的底平面均为光滑面，所述光滑面上设有胶水涂层。
如图1所示，在本发明的一个实施例中，所述金属灯具外壳四周由若干个带微结构柔性自锁器A面和冷轧钢板拉深成型的壳体组成，其中微结构柔性自锁器A面上设有可以任意折弯或揉捏的、不易容撕裂的、抗拉性强的尼龙PA或涤纶等材质制作而成的带状物。
该柔性自锁器A面的底平面为光滑面，敷有耐候强的强力胶，可以直接粘接在金属灯具外壳内侧的光洁面上；该柔性自锁器A面的正面布有无数细小O型圈或n型圈，直径大小不一，或倾斜或垂直于自锁器的基面上，能在外力的作用下会产生塑性变型，当外力消失后又能快速恢复原状。
其中，冷轧钢板拉深成型的壳体底平面为平整光滑面或带任意型状的凸筋面；所用的材质是对磁材有很强的吸附力的金属材料。
如图3所示，在本发明的另一个实施例中，扩散板为塑料扩散板，所述塑料扩散板的四边设有若干个带微结构柔性自锁器B面，其中微结构柔性自锁器B面上设有可以任意折弯或揉捏的、不易容撕裂的、抗拉性强的尼龙PA或涤纶等材质制作而成的带状物。

作为本发明的优选实施例，由于微结构柔性自锁器能在左右上下4个维度自由伸展1～2mm,所以给塑料扩散板在不同的气候条件下，产生的尺寸形变提供了足够的伸展空间，解决了现有的塑料扩散板由边框压在壳体上导致在热膨冷缩的情况下，没有伸展的空间，出现尺寸变形弯曲或断裂的情况。
请参见图2，图2是本发明提供的LED直发光面板灯的FFC灯板的一种实施例的结构示意图；

请参见图10，图10是本发明提供的LED直发光面板灯的一种实施例的整体结构示意图；
如图10所示，本发明提供的面板灯在生成工艺上可将生产过程简化为以下步骤：
第1步：将敷有强力胶水的带状微结构柔性自锁器A面，用机械手自动粘贴在灯具外壳内侧平面上；
第2步：将FFC灯板用自动机械手平铺在灯壳的底平面上，在灯板上面相应的位置放置永磁压条，由于外壳含大量Fe元素，所以永磁压条会将薄薄的FFC灯板紧紧的压在灯壳上；
第3步：用自动机械手将带磁性导线连接件放置在FFC灯板裸露抗氧化的焊盘上，由于导线连接件两侧底部微凸的金属弹片是相对应短路导通的，且导线连接件带有永磁，所以，在连接导通FFC灯板的同时，也能将FFC灯板紧紧的压在金属灯壳上；
第4步：将连接电线的带磁性的触头放置在FFC灯板输入电源端的裸露抗氧化的焊盘上，由于触头底部有微凸的金属弹片，且带有永磁，所以在连接导通灯板的同时，也会将FFC灯板紧紧的压在灯壳上；将触头尾部连接线通过壳体上的通孔引出壳体外，并用锁线器固定好引出的尾线；
第5步：将已粘贴好的带状微结构柔性自锁器B面的扩散板，用自动机械手吸起，放置在灯具壳全上；在扩散板平面施加一定压力，使扩散板上柔性自锁器B面微小的塑料钩和灯壳上柔性自锁器A面上微小的O型圈相互交错，自动锁紧。
本发明提供的LED直光面板灯，通过减少光源板用螺丝固定在灯具壳体的工序，从而减少了电源输出线焊接在灯板上的工序，以达到节省人力物力成本的目的；通过减少扩散板通过边框用螺丝固定在灯具壳体的工序，能够使得本发明提供的面板灯的整个生产过程均可采用自动化机械不分昼夜的大批量生产，进一步的节省了大量的人力物力成本。
作为本发明的优选实施例，本发明提供的LED直光面板灯在维修时，具有非常便捷的优点，无需专业的知识和工具即可完成拆装，具体的拆装过程如下：
第1步：切断灯具电源；
第2步：用手指捏紧扩散板的一角，用力向下扯，灯壳和扩散板上的微结构自锁器在外力作用下发生形变，自动分开，使扩散板同灯壳分离；
第3步：将有损坏灯珠的FFC灯板上的永磁压条和带磁性导线连接件，用手取下来，FFC灯板将会自动从灯壳上脱落；
第4步：取出LED灯珠，并放置完好的LED在FFC灯板上，然后用手将FFC灯板平覆在灯壳的底部，将刚取下来的永磁压条放置在适当的位置，由于磁力的作用下，FFC灯板会紧贴在灯壳；同时，在FFC灯板上焊盘位置放上带磁性导线连接件；
第5步：将带状微结构柔性自锁器B面的扩散板用手压在灯具壳体内，使自 锁器产生作用；
第6步：通电点灯。
本发明提供的LED直光面板灯，在出现故障需要维修时，无需专业的知识和工具便能轻易拆装，解决了现有的面板灯在出现故障时，没有相应的经验就无法完成维修的窘迫局面，同时节省了直接更换灯板、以及找维修人员来维修所花费的人力物力成本。
