Description

LED灯管
技术领域
本实用新型涉及一种LED灯管。
背景技术
现有LED灯管,包括透光罩、安装板和印刷板组件,所述印刷板组件固定于所述安装板上,所述安装板设于所述透光罩内,使灯管在正常安装完后无任何金属导电部件外露,安全可靠,但安装板散热有了很大程度的影响。
实用新型内容
本实用新型所要解决的技术问题是提供一种LED灯管,既安全可靠,又能有效散热。
为解决上述技术问题,本实用新型采用如下技术方案:LED灯管,包括透光罩、安装板和印刷板组件,所述印刷板组件固定于所述安装板上,所述安装板设于所述透光罩内,所述透光罩沿轴向设有一道开口,所述开口位于所述安装板的背侧。
作为优选,所述安装板的背侧设有至少一块散热板。
作为优选,所述安装板的背侧设有第一散热板、第二散热板,所述透光罩在开口处向罩体中央延伸有第三档板、第四挡板,所述第三档板、第四挡板夹持于所述第一散热板、第二散热板之间。
本实用新型由于采用了上述技术方案,在安装板的背侧的透光罩上沿轴向设有一道开口,可以获得更好的散热效果。
