Description

倾斜旋转组合 LED灯丝结构的灯泡
技术领域
本发明涉及一种 LED晶元封装成条状灯丝的 LED球泡灯，尤其是一种倾斜旋转组合 LED 灯丝结构及灯泡。
背景技术
LED是发光二极管 （LED, Lighting emitted diode) ,是利用在电场作用下， ΡΝ结发光 的固态发光器件。 具有高寿命 /环保 /节能的特点， 是绿色环保的新光源。
LED技术日趋发展成熟， 目前 LED白光是通过蓝色芯片激发黄绿荧光粉， 进行波长调 和而产生出的白光， 目前 LED的发光效率已经超过大部分传统光源。 一般而言， LED是通 过 MOCVD (Metal-organic Chemical Vapor Deposition, 金属有机化合物化学气相沉淀） 在外延片上长出 PN层及发光层， 然后通过点测、 扩散、 分 BIN等工艺做成不同尺寸的芯 片， 一般而言有 10*10 mil, 10*23 mil, 24*24 mil, 40*40 mil等尺寸， 可以承受从 10mA~lA 的恒流电流驱动。 传统的封装是将这些芯片固定在一个封装支架上， 通过金线焊接芯片的 阴极和阳极， 通入电流来驱动 LED发出蓝色单波长光， 从而激发荧光粉形成白光。 支架一 般釆用工程塑料或者是带金属热沉的塑料， 然后通过底部反射来增加其光萃取率， 或者是 通过硅胶成型或带二次光学透镜来改变内部材料的折射率， 从而增加其出光。
传统的封装方式， 对于 LED芯片的光利用率相当低， 特别是未能充分利用 LED芯片全 周光， 因此可以通过将 LED封装在玻璃基板上， 来增加其出光范围。 由于玻璃是热的不良 导体， 不能有效的快速将 LED芯片的热量快速的散发， 因此需要一层缓冲层来实现 LED的 芯片散热。
对 ΐ以玻璃等材料为基板的灯丝构成一体化 LED灯而言， 若干灯丝在做成串并联， 在 灯泡内呈现竖直状态， 因每根灯丝特有的配光曲线， 竖直的灯丝光强分布相互影响， 不能 使整个灯泡球型均匀发光， 即不能达到传统白炽灯的光分布效果。 因此， 需要针对 LED灯 丝特有的配光曲线， 调配多根灯丝的发光方向， 使光强分布相互影响， 达到球形均匀发光 效果。
发明内容
本发明是要解决 LED灯丝球泡灯的配光技术问题， 使其配光接近传统白炽灯的配光光 形， 而提供一种倾斜旋转组合 LED灯丝结构的灯泡。
为实现上述目的， 本发明的技术方案是： 一种倾斜旋转组合 LED灯丝结构的灯泡， 包 括 LED灯丝、接插座，其特点是： 若干根 LED灯丝分别***到接插座内， 且至少有一根 LED 灯丝与接插座的竖直方向倾斜一角度 Θ。
倾斜的角度 Θ为 0° < θ 90° 。
接插座固接在玻璃芯柱的金属杆上， 玻璃芯柱与泡壳烧结成一体。
本发明的有益效果：
本发明的优点是将若干 LED灯丝柱形分布的光经过重组、叠加，变为球型光，符合 360 度出光要求， 使灯泡的配光符合通用照明需求。
附图说明
图 1是本发明的结构立体示意图；
图 2是本发明的主视图。
具体实施方式
下面结合附图与实施例对本发明作进一步说明。
如图 1， 2所示， 本发明的倾斜旋转组合 LED灯丝结构的灯泡， 包括泡壳 1、 若干根 LED灯丝 2、 接插座 3、 玻璃芯柱 4、 灯头塑件 5、 灯头 6等。
LED灯丝 2***到接插座 3的斜孔内， 接插座 3固接在玻璃芯柱 4的金属杆上， 玻璃 芯柱 4与泡壳 1烧结成一体，然后与灯头塑件 5固接在一起， 灯头 6在灯头塑件 5上。 LED 灯丝 2在垂直于灯丝的平面内配光曲线是四个近似椭圆的配光曲线组合,将至少有一根 LED 灯丝 2与接插座 3的竖直方向倾斜一定角度 Θ时（图 2)， 光强分布指向发生改变，产生竖 直方向分量和水平方向分量。随着倾斜角度的变化，竖直分量和水平分量的比例发生变化。 当 LED灯丝 2围绕着灯泡中心轴按相同角度倾斜时， 光强在空间上形成以灯泡为中心的近 似球型均匀分布， 即与传统白炽灯的配光相似。 倾斜的角度 Θ范围大于 0度到 90度。
