Description

全方位LED发光球泡灯 技术领域
本发明涉及一种照明技术领域，特别是全方位LED发光球泡灯。
 背景技术
由于发光二极管为一种可将电能转换为光能的高效率冷光发光元件，并具有节能、环保 、高效率、小体积、长寿命等优点，故LED（Light Emitting Diode，发光二极管）灯具越来越受到人们的青睐，LED灯具代替传统的白炽灯和荧光灯已经成了一种主流趋势。由于LED具有指向性的特点，节能灯的LED球泡灯只能向前发光而不能向后发光，导致了现有市场的LED球泡的发光角度小于180°，这样，当照明环境需要全方位发光时，这种形式的球泡就不能被应用了，因此随着科技的发展就出现了一种全方位的球泡灯。
例如：如图1、图2、图3所示，国家专利局公布的专利号为201010583096.0的一种全方位LED球泡灯，包括有灯头1，散热壳体9、LED光源3和扩散灯罩5，所述散热壳体9腔体内设有LED驱动装置4，其特征是所述散热壳体9沿着轴向设有向外凸的平台8，平台8顶面设有LED光源3，所述LED光源3为柱头集成发光光源，其封装架体10设有多棱柱状头，在柱头的顶面和侧面均设有LED芯片11，架体10柱头后端设有环状反光面12，它主要是通过反光面实现灯体后端光通量大，实现全方位发光，但是由于这种结构的反光面的大小受到限制，因此导致该全方位LED球泡灯的全方位照明的效果不佳，因此需要改进。
 技术问题
本发明的目的是为了解决上述现有技术的不足而提供一种能够使灯具在各个方向发光均匀，实现发光角度大于270°，从而有效的实现了全方位发光的全方位LED发光球泡灯。
 技术解决方案
为了实现上述目的，本发明所设计的全方位LED发光球泡灯，包括灯头、壳体、LED光源、LED驱动装置、扩散灯罩和塑料底座，所述塑料底座设于壳体和灯头之间，所述壳体包括台面，所述扩散灯罩套设于整个台面上，所述的LED光源包括第一LED光源和第二LED光源，所述的第一LED光源嵌设于台面上方的内侧，所述第二LED光源设于台面的下侧相对于第一LED光源的背面上，且所述第一LED光源和第二LED光源的光照方向相反，在台面的下端的外壁上套设有反光杯，所述反光杯杯体上端的直径小于反光杯杯体下端的直径，在反光杯的外壁上相对于反光杯杯体的下端设有漫反射面。所述的漫反射面为一环及以上的内凹环状或外凸环状或外凸球状或内凸球状结构的漫反射面。
该结构的发光原理为：第一LED光源发出的光束经过扩散灯罩扩散后射向上方，同时光速经过扩散灯罩扩散后，角度增大，发光均匀；而第二LED光源发出的光束是朝向下方的，因此一部分光束经过扩散灯罩扩散后射向下方，一部分光束射向反光杯凹凸面的漫反射面反射后，方向改变，再经过扩散灯罩扩散后射向其他方向照射，这样多束光经过反光杯漫反射面和扩散灯罩扩散后，向各个方向发散，从而能使LED光源发光角度大于270°，发光均匀，从而有效的实现了全方位发光效果。
为了扩散角度更大，所述的扩散灯罩包括第一扩散灯罩和第二扩散灯罩，所述的第一扩散灯罩罩设于台面上端的第一LED光源外，所述的第二扩散灯罩罩设于台面的下端相对于反光杯的外侧。第一扩散灯罩和第二扩散灯罩可采用不同材料。
为了起到有效的扩散作用，所述壳体为散热结构，且包括分开设计的下散热体和台面，所述的LED驱动装置设于塑料底座内，且所述的下散热体与灯头之间通过塑料底座固定连接，所述的台面与下散热体连接。
为了使整体结构更加简单，在安装时减少安装时间，所述台面和下散热体为一体结构。
 有益效果
本发明得到的全方位LED发光球泡灯，通过上述的设计：第一LED光源发出的光束经过扩散灯罩扩散后射向上方，同时光速经过扩散灯罩扩散后，角度增大，发光均匀；而第二LED光源发出的光束是朝向下方的，因此一部分光束经过扩散灯罩扩散后射向下方，一部分光束射向反光杯凹凸面的漫反射面反射后，方向改变，再经过扩散灯罩扩散后射向其他方向照射，这样多束光经过反光杯漫反射面和扩散灯罩扩散后，向各个方向发散，从而能使LED光源发光角度大于270°，发光均匀，从而有效的实现了全方位发光效果。
