Description

防爆型信号指示灯
技术领域
本实用新型涉及带有防火或防爆装置的照明装置领域,具体为一种防爆型信号指示灯。 
背景技术
在爆炸性气体环境的照明必须使用防爆灯具,传统的电光源,如白炽灯、荧光灯都存在着使用寿命短,安装不方便,发光效率低的缺陷,造成防爆灯具的维护周期较短,电能消耗大。此外,各种规格的灯具互不兼容,各有一套零配件,又加大了安装、维护的工作量。 
实用新型内容
为了克服现有技术的缺陷,提供一种使用寿命长、发光效率高、安装方便、适用范围广的防爆照明装置,本实用新型公开了一种防爆型信号指示灯。 
本实用新型通过如下技术方案达到发明目的: 
一种防爆型信号指示灯,包括底座和灯座,灯座为一壳体,灯座的底部固定在底座上,其特征是:还包括驱动电路、发光二极管、内透明罩和外灯罩,内透明罩套在灯座内且内透明罩和灯座密封连接,内透明罩和灯座拼合成一密闭的空腔,驱动电路和发光二极管都设于所述的空腔内,驱动电路固定在灯座内,发光二极管设于内透明罩内,外灯罩套在灯座外且外灯罩和灯座密封连接。
所述的防爆型信号指示灯,其特征是:内透明罩和灯座通过隔爆螺纹密封连接,外灯罩和灯座通过隔爆螺纹密封连接。 
本实用新型选用寿命长、光效高、能耗低的发光二极管作为照明光源,寿命可长达50,000小时至100,000小时,实现了光源的节能免维护;灯具作防爆处理,可满足爆炸性气体及粉尘环境的防爆要求;结构简单紧凑,便于安装。本实用新型的有益效果是:使用寿命长,维护工作量少,安装方便,适用范围广。 
附图说明
图1是本实用新型的结构示意图。 
具体实施方式
以下通过具体实施例进一步说明本实用新型。 
实施例1 
一种防爆型信号指示灯,包括底座1、灯座2、驱动电路3、发光二极管4、内透明罩5和外灯罩6,如图1所示,具体结构是:灯座2为一壳体,灯座2的底部固定在底座1上,内透明罩5套在灯座2内且内透明罩5和灯座2通过隔爆螺纹密封连接,内透明罩5和灯座2拼合成一密闭的空腔,驱动电路3和发光二极管4都设于所述的空腔内,驱动电路3固定在灯座2内,发光二极管4设于内透明罩5内,外灯罩6套在灯座2外且外灯罩6和灯座2通过隔爆螺纹密封连接。

Claims (2)
