Abstract

本实用新型公开了一种自吸式防爆灯,包括灯具本体、灯具本体下部的透明罩,在透明罩底部设有防爆透气网孔,在灯具本体顶部设有防爆呼吸阀。本实用新型结构合理,透明罩底部有防爆透气网孔、灯具顶部有防爆呼吸阀,工作时能产生自吸式对流空气,达到降温效果,提高防爆灯具的温度组别,延长光源寿命。

Description

自吸式防爆灯
技术领域:
本实用新型涉及一种防爆灯。
背景技术:
现有的防爆灯,工作时,不能形成内部空气对流,降温效果不理想,使用寿命短。
发明内容:
本实用新型的目的在于提供一种结构合理,工作时能产生对流空气,光源使用寿命长的自吸式防爆灯。
本实用新型的技术解决方案是:
一种自吸式防爆灯,包括灯具本体、灯具本体下部的透明罩,其特征是:在透明罩底部设有防爆透气网孔,在灯具本体顶部设有防爆呼吸阀。
本实用新型结构合理,透明罩底部有防爆透气网孔、灯具顶部有防爆呼吸阀,工作时能产生自吸式对流空气,达到降温效果,提高防爆灯具的温度组别,延长光源寿命。
防爆灯工作时,随着光源的升温,灯具壳体内部空气受热,向上方流动,同时从底部防爆网孔吸入经网孔过滤的冷空气,产生自吸式对流空气,从而起到冷却作用,在不影响防爆性能的同时,提高防爆灯具的温度组别,延长光源寿命;当防爆灯具内部有冷凝水时,自然流动到灯具透明罩底部,通过具有渗透特性的网孔,将冷凝水排出。
附图说明:
图1是本实用新型一个实施例的结构示图。
具体实施方式:
一种自吸式防爆灯,包括灯具本体1、灯具本体下部的透明罩2,在透明罩底部设有防爆透气网孔3,在灯具本体顶部设有1~多个防爆呼吸阀4。
