背景技术
现有的 LED照明灯具是由不少于两颗的 LED点光源组成， LED光源 方向性很好，这导致在数颗 LED点光源集成为大功率照明灯具时会产生配 光困难的问题。
目前存在的各种 LED灯具， 大多没有摆脱传统灯具的束缚， 未考虑现 场配光曲线等问题， 严重影响了灯具的照明效果。 CN1821651 公开一种大 功率 LED路灯， 但其采用单颗 LED加装透镜， 制造工艺复杂， 而且会增加 光的损失， 通过分离透镜调整配光方向也很烦琐； CN2842182公开一种 LED 路灯， 考虑了 LED的安装角度， 但拼装结构面太多， 工艺复杂。

具体实施方式
本发明的 LED照明灯具， 包括 LED光源 3和散热体 1， 所述散热体 1 上设置有安装面阵列， 所述 LED光源 3安装在所述安装面阵列上。
上述安装面阵列是中部为平面、 平面四周至少有一侧有安装面阵列， 且安装面阵列为安装斜面阵列或安装曲面阵列。 例如： 可以采用中部为平 面、 平面两侧为安装斜面阵列的安装面， 如图 1所示； 也可采用中部为平 面、 平面四周为安装斜面阵列的安装面， 如图 2所示； 还可以采用其它方 式。
上述安装斜面阵列最好采用锯齿状安装斜面 2或锯齿状安装曲面， 如 图 1和图 5所示。
上述散热体 1安装在支撑框架 6上， 如图 3所示， 上述锯齿状安装斜 面 2与散热体 1的水平面夹角《，且 3° ≤«≤60° ，每个锯齿状安装斜面 2 与散热体 1的水平面夹角 可以不同， 以便于在不同方向上的光线调整， 锯齿状安装斜面 2的倾斜方向可以朝向任意方向， 以满足不同区域的照明 需求， 例如， 当本发明作为人行道上的路灯使用时， 锯齿状安装斜面 2的 倾斜方向最好朝向人行道， 使 LED光源 3发出的光线更多的分配在人行道 上， 以满足使用需求。
LED光源 3可以通过导热硅胶和连接螺钉固定在散热体 1上的锯齿状安 装斜面 2上， 可获得从 LED光源 3到散热体 1的良好的散热效果。 锯齿状 安装斜面 2可以根据 LED光源 3的安装需要进行设计， 可以是平面， 如图 4所示； 也可以是曲面， 如图 5所示。
LED光源 3的发光角度 最好选择在 30° ≤ ≤120° 的范围内，这样可 以配合散热体 1上的锯齿状安装斜面 2的倾斜角度^ 满足不同高度灯具 的照射范围的需求。 例如： 根据路灯灯杆的不同高度， 可以调节锯齿状安 装斜面 2与散热体 1水平面的角度 、 选择 LED的发光角度 ^， 以获得最 佳的配光曲线。

—本发明的散热体 1和安装面阵列采用机械加工或者铸造等方法一体化 加工形成一个整体， 其材料可以采用导热性能好的铝或铜。 这种一体化的 结构避免了将散热体 1和 LED光源 3的安装面分开， 从而减少了多个接触 面之间的接触热阻， 增加了热传导效率， 散热能力更好。
散热体 1的整体外形形状可以根据需要， 采用长方体形、 球形、 椭球 形或其他形状， 如图 1所示的长方体形， 如图 6所示的椭球形。 散热体 1 可以采用散热片的形式， 散热片可以采用规则的直齿排列， 如图 3和图 4 所示， 也可以采用曲面形状， 如图 5所示， 还可以采用其他形状。 其中， 直齿^ ^列方式容易加工实现， 散热面积大小也容易计算， 而曲面形状的散 热片造型美观， 符合一些特殊场合的审美需要。
+ 本发明的散热体 1与支撑框架 6采用独立的两大部份， 支撑框架 6可 以采用长方形或圆弧形， 如图 3和图 7所示， 还可以采用其它造型， 以实 现灯具外观的多样化， 满足不同的装饰和搭配需要。 支撑框架 6上还设置 有挡雨外壳 8， 挡雨外壳 8可保护恒流驱动器 9等部件， 挡雨外壳 8可采 用活页 4安装在支撑框架 6上， 挡雨外壳 8的安装位置不能挡住散热体 1， 避免影响散热能力， 本发明盖上挡雨外壳 8后的俯视图如图 7所示， 揭开 挡雨外壳 8后的俯视图如图 8所示。
透明灯罩 5安装在散热体 1上， 透明灯罩 5可保护 LED光源 3并使灯 具外形美观。散热体 1、 LED光源 3和透明灯罩 5组成一个整体通过螺钉或 扣件安装在支撑框架 6上。 恒流驱动器 9用螺钉固定在支撑框架 6上， 恒 流驱动器 9为 LED光源 3提供稳定的工作电流。 支撑框架 6通过安装孔 10 与灯杆连接在一起。
为了更有利于本发明的配光， 本发明的散热体 1的水平面还可设置成 曲面， 如图 9所示。
虽然本发明参考优选的实施例进行了图示和描述， 但是， 本专业普通 技术人员应当了解， 在权利要求书的范围内， 可作形式和细节上的各种各 样的变化。
