Description

LED照明灯
技术领域
本发明涉及照明装置领域，是一种LED照明灯。
背景技术
众所周知，黑夜中工作和生活的人们离不开照明。原始社会黑夜中的亮光靠自然光、原材料所产生的光照明，经过漫长的历史长河，爱迪生发明了电灯，尔后照明器具又经过不断地更新换代。现代化进程中的人们在关注照明器具款式的同时，又十分注重节约能源。近几年科技较发达的国家正在研究用于照明的大功率LED灯，但仅仅停留在实验室研究阶段。目前，小功率LED已被广泛应用于指示灯、装饰灯、手电筒。随着白色发光二极管LED发光效率的不断提高，LED照明灯从装饰功能转为照明功能已成为可能。尽管LED照明灯属冷光源，但其发光时所产生的热量仍然很大，如不采取措施降低热量，最终将导致LED照明灯使用寿命的缩短。中国专利文献近年披露了有关LED照明灯专利技术，但尚未刊载头罩与散热铝罩，散热铝罩内设置风扇，风扇的外壳设有叶片，风扇的内腔设置定子和转子的相关技术。
发明内容
本发明的目的是向本领域提供一种LED照明灯，使其可以解决现有的照明灯耗电较高，亮度不足，散热问题尚未完善的技术问题。本发明的目的是采用如下的技术方案实现的。
一种LED照明灯，该照明灯主要由头罩、LED板、散热铝罩、风扇、电路板、尾盖、针座、插针、LED发光管所构成，其要点是头罩与LED板、LED发光管对应设置，头罩的延伸块与散热铝罩由螺钉连接固定，在散热铝罩内设置风扇；风扇的外壳设有叶片，风扇的内腔设置定子和转子，定子和转子构成微型电机。风扇连接尾盖内的电路板，尾盖与散热铝罩由螺钉连接固定，尾盖连接针座、插针，电路板的电源线通过尾盖、针座、连接插针。
所述的LED照明灯的头罩中的孔眼、LED板中的LED发光管按对应只数稀少排列。LED照明灯B头罩中的孔眼、LED板中的LED发光管，另设为按对应只数密集排列。LED发光管按对应只数稀少排列或按数密集排列，为的是根据不同的需求而设置不同的亮度。
所述的LED照明灯的散热铝罩的散热片是沿着铝罩连体布设，并呈弧形。这种结构既达到散热的目的，外形又比较美观。所述的散热铝罩的四周及尾盖上设有通槽，灯体内的热空气与散热铝罩的四周、通槽是相通的。
这种LED照明灯具有的照明耗电低、亮度高，散热好的特点。使用寿命长，达到节能的效果。
附图说明
图1是本发明结构示意图，也称***图。
图2是LED照明灯组装后的主视示意图，LED发光管按对应只数稀少排列。
图3是图2的仰视示意图。
图4是图2的俯视示意图。
图5是图2的右视示意图。

图8是本发明LED发光管只数密集排列示意图。
图9是本发明LED发光管只数密集排列立体状态示意图。
图10是本发明结构中LED发光管只数密集排列***图。
以上附图序号及名称：1、头罩，2、LED板，3、散热铝罩，4、螺钉，5、风扇，6、电路板，7、尾盖，8、针座，9、插针，10、LED发光管，11、B头罩。
具体实施方式
实施方式以安装为例，图1、图10省略了电源线的绘制，特加之说明。首先将从电路板6上输出的两根电源线穿过散热铝罩3，与LED板2(上面布置贴片LED发光管10)的正负极焊盘相焊，再将LED板2用螺钉4紧固在散热铝罩3上。电路板6上的两根输入线分别与两根插针9相联。交流电220v/110v市电(或交流12v低电压)经过插针输入到电路板6上，经过元器件整流、降压，稳流之后，得到恒定直流电，驱动贴片LED发光管10发光。头罩的延伸块由螺钉连接固定散热铝罩，在散热铝罩内设置风扇；风扇的外壳设有叶片，风扇的内腔由定子和转子构成微型电机。如图7所示，组装的插针9与尾盖7、针座8连接体***LED照明灯座，接通电源LED发光管10就亮了。尽管LED照明灯属冷光，但散热铝罩产生一定的热量须通过微型电机转动叶片，将散热铝罩内的热量经散热片散发。因圆弧形散热面积大，故将散热片设为弧形，并沿着铝罩连体布设，使其外形比较美观，又有良好的散热效果。另外在散热铝罩的四周及尾盖7上设有通槽，使外部的冷空气通过尾盖进入，而灯体内的热空气又通过散热铝罩四周的通槽排出，从而使空气有效的对流；同时这些通槽还成倍的增加了散热表面积，起到极佳的散热效果。
