Abstract

本发明涉及白炽灯。包括两个电极、灯丝和灯泡,灯丝串接于两个电极之间,灯丝外表面上还镀有一层金刚石膜。由于灯丝外镀有一层透明的金刚石膜,即使当灯丝加热到极高的接近熔点的温度时,由于有金刚石膜的保护,灯丝不会再蒸发,因此,解决了现有的白炽灯发光效率不高和使用寿命不长的技术问题。

Description

一种新型白炽灯
技术领域
本发明涉及白炽灯。
现有技术
用现有的白炽灯由两个电极、灯丝和灯泡组成,灯丝串接于两个电极之间。灯丝在通电以后发热,当热量达到一定程度后发出可见光,温度越高,发出的光的波长越短,也越亮,发光效率也随之大大提高,但是,温度越高灯丝的蒸发速度也越快,灯丝的使用寿命大大缩短导致灯的寿命也相应缩短,因此,白炽灯往往以低效率来换取长一些的寿命。
发明内容
本发明要解决的是现有的白炽灯发光效率不高和使用寿命不长的技术问题。
为了解决以上技术问题,本发明采取的技术方案是
一种新型白炽灯,包括两个电极、灯丝和灯泡,灯丝串接于两个电极之间,其特征是所述的灯丝外表面上还镀有一层金刚石膜。
在采用了以上技术方案后,由于灯丝外镀有一层透明的金刚石膜,而金刚石膜具有良好的良好的透光性和导热性,熔点也大大高于灯丝的温度,即使当灯丝加热到极高的接近熔点的温度时,由于有金刚石膜的保护,灯丝不会再蒸发,因此,解决了现有的白炽灯发光效率不高和使用寿命不长的技术问题。
附图说明
图1是本发明的立体结构示意图。
具体实施方式
一种新型白炽灯,包括两个电极1,11、灯丝2和灯泡3,灯丝2串接于两个电极1,11之间,灯丝外表面上还镀有一层金刚石膜,灯丝一般为钨丝。
