What is the spectrum of xenon?
Even though xenon lamps produce broadband, almost continuous emission having a color temperature approximating sunlight in the visible wavelengths (often referred to as white light), they do exhibit a complex line spectrum in the 750 to 1000 nanometer region of the near-infrared spectrum (see Figure 1).
How does a xenon lamp work?
A xenon arc lamp is a special type of gas discharge lamp. Xenon arc lamps produce light by passing electricity through ionized xenon gas at high pressure. It produces a bright white light that closely mimics natural sunlight, which extends its applications into the film, and daylight simulation industries.
What is a xenon light source?
Xenon light sources offer very high intensity in the UV and are useful for absorbance, fluorescence or reflectance measurements. Pulsed xenon sources are high intensity with a lower duty cycle, making them ideal for measurements where high intensity UV light can damage the sample.
What is xenon light?
What is a Xenon Light? A xenon — also known as a high-intensity discharge or HID light — is a gas-filled, very bright, and energy-efficient light. Xenon lights are fairly common in luxury vehicles you see on the road today.
What lights are better xenon or LED?
LEDs are about 90% more efficient than incandescent bulbs and generate less heat. LEDs last longer than either halogens or xenon light, though they become dimmer as they age.
What color is xenon light?
white-blue light
Xenon headlights have a colour temperature of 4000K-6000K, which is a bright white-blue light similar to natural daylight and halogen headlights have a colour temperature of 3200-5000K, which is a warmer, yellow-white light.
Is xenon or halogen better?
Also known as High-Intensity Discharge (HID) lamps, xenon headlights deliver a white-blue light, approximately two to three times brighter than a halogen, last approximately 2,500 hours and are energy efficient.
How do xenon lights work?
There is no filament inside HID xenon bulbs. Instead, a combination of an electrical charge and xenon gas is used to produce the light. When the gas is excited by the electrical charge, it emits a much brighter, whiter light than that produced by halogen bulbs.
What is the difference between xenon and LED lights?
Xenon Headlights They use less energy than halogens and more than LEDs. They also are hotter than LEDs and become dimmer over time. In an xenon headlight, electric current passes through the xenon gas to create an arc between two electrodes and generate intense white or bluish light that is often brighter than LEDs.
What is the emission spectrum of Xe arc lamps?
Xenon (Xe) arc lamps have a relatively smooth emission curve in the UV to visible spectrums, with characteristic wavelengths emitted from 750-1000 nm. Their sun-like emission spectrum and ~5800 K color temperature make them a popular choice for solar simulation, as well as absorption and fluorescence and source spectral scanning applications.
What is the intensity of light emitted from a xenon lamp?
Pure xenon. However, even in a high pressure lamp there are some very strong emission lines in the near infrared, roughly in the region from 850–900 nm. This spectral region can contain about 10% of the total emitted light. [citation needed] Light intensity ranges from 20,000 to 500,000 cd/cm 2.
Does the Xe lamp cause photochemistry in the troposphere?
The Xe lamp also has a series of peaks in the 800- to 1000-nm region that do not appear in sunlight. This relatively low-energy radiation does not cause significant photochemistry in the troposphere. However, if desired, the intensity of these peaks can be decreased with the use of appropriate filters.
What is an ozone free Xe arc lamp?
An ozone free lamp is coated to remove the unwanted UV Wavelengths When additional UV output from the xenon lamp is required, UV-enhanced lamps are available. These lamps provide the same visible to NIR performance of an standard Xe arc lamp while providing high intensity UV output as well.
