Xenon Arc Lamp
A Xenon Arc Lamp is an artificial light source. Powered by electricity, it uses ionized xenon gas to produce a bright white light that closely mimics natural daylight. Xenon arc lamps can be roughly divided into three categories:
- Continuous-output xenon short-arc lamps
- Continuous-output xenon long-arc lamps
- Xenon flash lamps (which are usually considered separately)
Each consists of a glass or fused quartz arc tube with tungsten metal electrodes at each end. The glass tube is first evacuated and then re-filled with xenon gas. For xenon flashtubes, a third "trigger" electrode usually surrounds the exterior of the arc tube. |
