High Pressure Ionized Xenon Gas Make for the Best Lamps 21 October 2018 | Posted in

Arc light lamps are so bright it's like having a flashlight that shines daylight on wherever you go. This is why they're used in industries and research studies to simulate light, like in the case of growing marijuana with daylight lamps as well as product testing on the bleaching effects of light on cloth. They're also extensively used in film projectors and searchlights as well as stage floodlights. The electronicx arc light lamp has many uses indeed. Headlamps using arc light technology are actually metal-halide headlights, with the gas arc seldom used during startup for the sake of color temperature correction. What's more, there are many types of xenon-arc lamps to choose from for good measure.

 

The Many Types of Arc Lamps

  • Continuous-Output-Xenon Short-Arc Lamps: It's a lamp that consists of fused quartz or other glass arc tubes that are heat-resistant. At every end of the tube there's a tungsten metal electrode. The glass tube is first evacuated of air. From there, it's refilled with xenon-gas. Short-arc lamps have negative temperature coefficient, which is about the same as other lamps of the gas discharge variety. They're run at high-current and low-wattage DC then started up with 20kV to 50vV of high voltage.
  • Continuous-Output-Xenon Long-Arc Lamps: As for continuous-output long-arc lamps with xenon-gas in them, they're structurally the same as the short-arc type of lamps. However, the main difference with them is the distance between the electrodes because the glass tube is longer, thus producing a longer arc compared to its counterpart. Their applications include material inspection, rapid thermal processing, age-testing of materials through solar or daylight simulation, and solar cell testing.
  • Xenon-Flash Lamps: A flash lamp or flash tube is an electrical arc lamp designed to make a short-duration full-spectrum, extremely intense, and incoherent white light. They also use glass tubing and are also mostly used for photography. As a result, they simulate sunlight in brief flashes when mounted within an elliptical reflector. They're also used in entertainment, industrial, medical, and scientific circumstances. They work by triggering the xenon-gas to ionize and conduct high voltage pulses.
