技术介绍
发光二极管简称为LED,由含镓(Ga)、砷(As)、磷(P)、氮(N)等的化合物制成。它是半导体二极管的一种,可以把电能转化成光能。发光二极管与普通二极管一样是由一个PN结组成,也具有单向导电性。当给发光二极管加上正向电压后,从P区注入到N区的空穴和由N区注入到P区的电子,在PN结附近数微米内分别与N区的电子和P区的空穴复合,产生自发辐射的荧光。不同的半导体材料中电子和空穴所处的能量状态不同。当电子和空穴复合时释放出的能量多少不同,释放出的能量越多,则发出的光的波长越短。随着LED照明技术的进步,LED灯具以其节能、寿命长、绿色环保等优点逐步取代传统的照明领域的白炽灯、节能灯,被人们所接受和认可。但市面上的大多数LED灯泡都是半罩的灯泡,如图1所示,图1为现有技术中LED灯泡的结构示意图,专利号为201620558943.0的中国专利,公开了一种LED灯泡,包括灯头螺帽100、连接于所述灯头螺帽上端的灯座200、安装于所述灯座200中的LED光源结构、 ...
