LED灯泡的新型散热结构
技术领域：
本实用新型主要涉及一种灯泡的结构，尤其涉及一种LED灯泡的新型散热结构。
背景技术：
目前，LED只能用于普通照明，若要提高灯光亮度，其温度也会提高。同时限于灯泡内部尺寸有限，因此也很难在一块线路板上安装很多的LED，美国照明公司(LIGHT OF AMERICAN)采用了在一块板上焊接多棵LED并将LED分层的方法来解决散热和数量问题，但会在安全和加工过程中出现问题，其LED管脚有可能接触，发生短路现象。
实用新型内容：
本实用新型目的就是为了弥补已有技术的缺陷，提供一种LED灯泡的新型散热结构，它能在提高灯光亮度的同时，不会出现温度过高的现象。
本实用新型是通过以下技术方案实现的：
LED灯泡的新型散热结构，包括有灯座、泡壳、LED灯管，其特征在于包括多层电路板；每层电路板上植接有一个或多个LED灯管，LED灯管的管脚接入所植电路板上印制的电路中；多层电路通过支架搭接成层结构，或者上层电路板粘结于其下层电路板上的LED灯管顶部搭接成层结构；各层电路板上所印制的电路相互电连接，并接入灯座内的接线柱上。
所述的LED灯泡的新型散热结构，其特征在于所述的位于下层的电路板上植接的LED灯管数量多于其上层的电路板上植接的LED灯管数量。
所述的LED灯泡的新型散热结构，其特征在于所述的电路板为二层至四层。是设计底座采用塑料，泡壳采用玻璃，用胶沾接.
本实用新型的灯座采用塑料制作，泡壳采用玻璃制作，用胶将灯座和灯泡沾接为一体。所述管脚与电路板间留有一定的间隙，并通过导线、支架与内部电路连接。
本实用新型的层数可以为多层次，其具体数量可由灯泡的空间和LED的使用数量来决定。
本实用新型的优点是：
本实用新型采用多层次电路板，在解决多棵LED安装的空间问题的同时，也解决了灯泡的散热问题，从而可以提高光的亮度，减少光衰。
