Description

一种全照明灯泡
技术领域
本发明涉及一种灯泡，具体涉及全照明灯泡，属于灯具技术领域。
背景技术
灯泡一般包括灯头、灯体、灯罩和固定在灯体内的光源，光源大多采用单颗光源向灯体方向照射，降低了灯泡的亮度；如若采用多颗低电流LED串联及并联来增加照明度，电路复杂且接点多、故障率高、稳定度差；且现有LED灯泡的最大照明范围可达180°，对于一些照明度要求高的场所无法实现全照明，始终有阴影面积的存在；大功率LED灯泡会产生高温，如果使用大型散热器来辅助散热，不仅影响了灯泡的造型美观，还会增加成本；还有一种散热方式是在LED下方涂抹导热膏再用螺丝平贴固定于散热器之上，然而导热胶的导热性较差，散热效果极为有限。
发明内容
针对现有技术的不足，现提供一种全照明灯泡，真正实现360°的照明范围，散热效果好，发光稳定，使用寿命长。
为实现上述目的，一种全照明灯泡，包括灯头、灯罩和发光源，发光源设在灯罩内，灯头连接在灯罩顶端，所述发光源为双面COB光源，COB光源上下两层集成多个LED芯片，上端LED芯片照射方向向上，下端LED芯片照射方向向下；发光源中间设有圆柱形散热器，灯头下连接有驱动电源，所述灯罩为全透明材质。
COB光源是一种将LED芯片直接贴在高反光率镜面金属基板上的高光效集成面光源技术，本发明采用双面COB光源，在双层基板上上下对称地集成两面光源，分别朝向上下发光，真正达到全照明。
进一步的，圆柱型散热器顶部的灯罩上开有散热孔；所述圆柱型散热器为中空结构，侧壁上开有散热凹槽。采用圆柱形散热器将光源热量通过顶部散热孔排出，散热器侧壁具有散热凹槽，热量传递接触面大，散热效果好。
进一步的，所述灯罩采用抗老化全透明扩散光PC材质。
进一步的，所述圆柱形散热器采用航空铝材制成。导热效果优良，具有抗腐蚀性，提高散热器和灯泡的使用寿命。
进一步的，所述灯罩底部为半球面，上部为圆锥形。
本发明通过双面COB光源与透明灯罩配合的结构达到了360°全照明，不存在照明死角，且发光稳定；散热器采用带散热凹槽的圆柱形，散热效果好，结构简单，提高了灯泡的使用寿命。
附图说明
图1为本发明结构示意图。
具体实施方式
下面结合附图对本发明作进一步说明。
如图1所示，一种全照明灯泡，包括灯头1、灯罩2和发光源3，发光源3设在灯罩2内，灯头1连接在灯罩2顶端，所述发光源3为双面COB光源，COB光源上下两层集成多个LED 芯片，上端LED芯片照射方向向上，下端LED芯片照射方向向下；发光源3中间设有圆柱形散热器4，灯头1下连接有驱动电源5，所述灯罩2为全透明材质。

进一步的，圆柱型散热器4顶部的灯罩上开有散热孔6；所述圆柱型散热器4为中空结构，侧壁上开有散热凹槽。采用圆柱形散热器将光源热量通过顶部散热孔排出，散热器侧壁具有散热凹槽，热量传递接触面大，散热效果好。
进一步的，所述灯罩2采用抗老化全透明扩散光PC材质。
进一步的，所述圆柱形散热器4采用航空铝材制成。导热效果优良，具有抗腐蚀性，提高散热器和灯泡的使用寿命。
