Description

带风扇的LED灯泡及制造方法 技术领域

背景技术
CN200910105878.0公开了一种“带有风扇的大功率LED灯结构”,它的目的是提供一种通过风扇对散热体、金属基板进行有效的散热,使LED发光体保持较低的工作温度,有利于LED灯发挥正常的功效。另外在LED发光体前端设有光学部件,可对LED光线进行漫射、反光和/或聚光作用,可以满足各种场合需要的带有风扇的大功率LED灯结构。该技术方案: 包括大功率LED发光体、用于固定大功率LED发光体的金属基板和与金属基板联接的散热体,金属基板设于散热体的前端,还设有一风扇,散热体为设有中空管腔的管状体,风扇固定于散热体尾端的中心。散热体外圆环设有若干个散热翅片,LED发光体之外端设有用于LED光处理的光学部件,且于散热体之尾端环设有灯头部件,灯头部件内设有LED驱动电路。其不足之处是: 该LED灯结构设置的风扇仅用于对散热翅片进行冷却，而未设置内腔的空气流动通道。因而，散热效果较差。
另外，小型LED灯泡，用自带功能排热，维持适当温度。但在同样规格的灯泡内需要更大光通量的灯泡时，散热就成了问题。
