【技术实现步骤摘要】
平行曝光汞氙灯
本技术涉及照明灯具
,尤其是一种平行曝光汞氙灯。
技术介绍
现有平行曝光汞氙灯结构中,安装钨棒的套管在封装时,套管朝向石英泡壳侧的前端面极易出现变形,造成应力集中而影响钼片封装效果,过高的内应力还容易在灯具使用产生爆裂炸灯现象。
技术实现思路
本技术要解决的技术问题是:为了克服现有技术中之不足,本技术提供一种可有效防止封装应力集中、提高使用安全性的平行曝光汞氙灯。本技术解决其技术问题所采用的技术方案是:一种平行曝光汞氙灯,具有泡壳、位于泡壳两端收缩形成的石英管以及设置在泡壳内的阴极和阳极,阴极连接有阴极钼杆,阳极连接有阳极钼杆,所述的石英管前端分别设有穿设过阴极钼杆的阴极套管和穿设过阳极钼杆的阳极套管,阴极套管后端的石英管内设有阴极石英柱,阳极套管后端的石英管内设有阳极石英柱,所述的阴极套管朝向泡壳的前端面具有第一碗形凹腔,阳极套管朝向泡壳的前端面具有第二碗形凹腔。所述的石英管后端安装有后套管,后套管内穿设有后钼杆,阴极钼杆与后钼杆、阳极钼杆与后钼杆之间均通过钼片连接。进一步地,所述的阴极石英柱和阳极石英柱均由前锥体、后锥体以及位于前锥体与后椎体之间的柱体构成,其中后锥体位于后套管侧。本技术的有益效果是:本技术在阴极套管和阳极套管的前端面均设置碗形状的凹腔,以此消除封装过程中的应力集中,提高阴极钼杆和阳极钼杆的安装牢固性,防止了应力集中造成灯具内部爆裂而炸灯情况的发生,提高了汞氙灯的使用安全性。附图说明下面结合附图和实施 ...
