Description
—种LED照明灯具
技术领域
[0001] 本发明涉及LED灯具技术领域，尤其涉及一种LED照明灯具。
背景技术
[0002] 由于LED照明灯具具有使用寿命长、启动时间短、节能效果显著、没有紫外辐射和环境污染、使用安全性能高等优势，得到广泛的认可，已经成为未来节能灯具的主流。
[0003] 但是，由于LED灯是个光电器件，在其光电转换过程之中只有15〜25%的电能转换成光能，其余的电能几乎都转换成热能，使LED灯具的温度升高。倘若LED灯的散热效果不好将会造成灯具的光效下降，甚至影响整个灯具的使用寿命。LED作为211光源，需要增加 散热装置和电源AC to DC装置造成LED灯泡无法像传统光源4n发光，又因发热影响电源和光源效率，光通量衰减。现市场存在大量LED灯具与传统灯座不配的现象。
[0004]
发明内容
[0005] 本发明的目的在于针对上述问题不足之处，提供一种LED照明灯具，具有散热效果好、减轻光通量衰减、光效率高、适用性高、易推广和生产成本低的优点。
[0006] 为了达到上述目的，本发明采用以下技术方案：
一种LED照明灯具，它设有灯头、设于灯头上端且由阻燃材料组制成的隔离套、装设在隔离套内腔的电源、套设在隔离套上端且由金属材料制成的散热主体、设于散热主体上端的基板、固接于基板上端发光单体，和罩设于散热主体上端的透光罩；所述灯头与电源电连接；所述电源与发光单体电连接。
[0007] 所述基板上至少设有一个发光单体。
[0008] 所述散热主体为表面带散热涂层的散热主体；所述散热涂层为纳米散热涂层。
[0009] 所述发光单体采用矩阵或圆周排列在基板上。
[0010] 所述透光罩为呈球形的球形式透光罩，或为呈一端往另一端逐步缩窄的拉尾式透光罩，或为呈椭圆状的蜡烛式透光罩，或为呈球形片状的片状式透光罩。
[0011 ] 所述隔离套下端外侧壁至少设有一个贯通隔离套部内的透气孔。
[0012] 所述散热主体内侧壁至少设有一条用于定位的定位凹槽和至少一条导胶槽；所述隔离套上端外侧壁至少设有一条与定位凹槽相对应的凸缘。
[0013] 所述基板为PCB金属基板，例如PCB铝金属基板。
[0014] 所述发光单体为由2n通过基板叠加后形成4n光束角的矩阵发光条单体。
[0015] 作为优选，所述PCB铝金属基板上按一定角度安装有三个矩阵发光单体，通过散热体内部机构调整矩阵发光条单体安装角达到通体发光的效果。
[0016] 本发明采用上述结构，具有散热效果好、减轻光通量衰减、光效率高、适用性高、易推广和生产成本低的优点。附图说明
[0017] 图I为本发明组装成一体的结构示意图。
[0018] 图2为本发明分拆的结构示意图。
[0019] 图3为本发明三个发光单体的立体示意图。
[0020] 图4为本发明发光单体、基板和散热主体的组合结构示意图。
[0021] 图5为本发明隔离套的正面示意图。
[0022] 图6为本发明球形式透光罩示意图。 [0023] 图7为本发明拉尾式透光罩示意图。

[0028] 以下通过附图和具体实施方式来对本发明作进一步描述。
具体实施方式
[0029] 如图I至图11所示，本发明一种LED照明灯具，它设有灯头7、设于灯头7上端且由阻燃材料组制成的隔离套6、装设在隔离套6内腔的电源5、套设在隔离套6上端且由金属材料制成的散热主体4、设于散热主体4上端的基板3、固接于基板3上端发光单体2，和罩设于散热主体4上端的透光罩I ;所述灯头7与电源5电连接；所述电源5与发光单体2电连接。
[0030] 所述基板3上至少设有一个发光单体2。
[0031] 所述散热主体4为表面带散热涂层的散热主体；所述散热涂层为纳米散热涂层。
[0032] 所述发光单体2采用矩阵或圆周排列在基板3上。
[0033] 所述透光罩I为呈球形的球形式透光罩，或为呈一端往另一端逐步缩窄的拉尾式透光罩，或为呈椭圆状的蜡烛式透光罩，或为呈球形片状的片状式透光罩。
[0034] 所述隔离套6下端外侧壁至少设有一个贯通隔离套部内的透气孔。
[0035] 所述散热主体4内侧壁至少设有一条用于定位的定位凹槽和至少一条导胶槽；所述隔离套6上端外侧壁至少设有一条与定位凹槽相对应的凸缘61。
[0036] 所述发光单体2为由2n通过基板叠加后形成4n光束角的矩阵发光条单体。
[0037] 所述灯头7可制作成传统照明灯泡灯头E14、E27、E40或欧规标称灯头，实现完全互换，以降低更换灯具的制造成本，代替传统球泡。
[0038] 所述基板3为PCB金属基板，例如PCB铝金属基板。
[0039] 所述发光单体2为由211通过基板叠加后形成411光束角的矩阵发光条单体。
[0040] 作为优选，所述PCB铝金属基板3上按一定角度安装有三个矩阵发光单体2，通过散热体内部机构调整矩阵发光条单体2安装角达到通体发光的效果。
[0041] 由发光单体2加裝透光罩I后形成最大出光率设计的矩阵发光条单体，减少因透光罩带来的光损。
[0042] 釆用热沉原理设计散热机构和表面散热绝缘纳米涂层处理，完成发热到蓄热再到单向向空气中散热，电源5和矩阵发光条单体2 —次绝缘。[0043] 采用塑胶连接隔热套兼绝缘套安放电源5驱动，实现标准欧规头和散热主体连接，并使电源5和灯头7，和散热主体二次绝缘。
[0044] 所述散热主体4通过压铸工艺和表面绿色处理将工作时产生热量单向导出，在空气中散热。透光罩I采用传统光学玻璃材料和工艺制成，最大限度减少LED照明灯具点亮后光通量输出衰减，同时隔离人体接触。通过对透光罩I外形和表面处理解决LED点光源的眩光。将SMT封装规格的发光单体2机帖到基板上，粘贴基板组成矩阵发光单体。通过不同数量的发光单体2可组成不同功率LED照明灯具。
[0045] 散热主体4由AL合金金属材料压铸成型。根据热传导特性,将各发光单体点亮后热量热沉散热主体4，带发光单体2的基板3与散热主体4紧密配合形成合理的单向导热结构。再通过散热主体的散热涂层将热量向空气中散去，同时具有阻断外界热量侵入的优点。图9为本发明单向热沉原理图。散热主体4实现LED照明灯具内部与外部表面绝缘隔离和加速热扩散。图4为本发明通过光学软体设计330°发光角，确定散热主体4内部与发光单 体2的安裝角度。图11为蝙蝠异形配光。散热主体4内部増加凹槽和导胶槽，其在与隔热套和透光罩连接时简洁安装。
[0046] 隔离套6采用阻燃工程材料注胶工艺。其实现三种功能，第一配合欧规专用灯头做灯具输入端，并实现两种欧规专用灯头可互用；第二，实现电源5与散热主体4和灯头7五金隔离形成二次隔离，同时灌胶实现电源5与散热主体4和发光单体2，第一次隔离，LED灯泡通过欧规标准传统灯头；第三，隔离套6与散热主体4连接后透气孔62形成散热孔，増加热量单向导出，达到最佳散热效果。
[0047]图10为整体热沉散热原理图，利用隔离套有特制散热透气孔加强与外界作热对流，热量通过透气盲孔与空气单向对流。
[0048] 本发明采用上述结构，具有散热效果好、减轻光通量衰减、光效率高、适用性高、易推广和生产成本低的优点。
[0049] 以上说明并非限制本发明的技术方案，凡是不脱离本发明精神的技术，均属于本发明的权利要求范围内。
