What is 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 the function of xenon lamp?
Xenon-mercury short-arc lamps have a bluish-white spectrum and extremely high UV output. These lamps are used primarily for UV curing applications, sterilizing objects, and generating ozone.
How does a deuterium lamp work?
Principle of operation A deuterium lamp uses a tungsten filament and anode placed on opposite sides of a nickel box structure designed to produce the best output spectrum. Unlike an incandescent bulb, the filament is not the source of light in deuterium lamps.
Is xenon arc incandescent or fluorescent?
Xenon lights are a type of High Intensity Discharge Lamp. These lamps create light by passing a current through a gas – similar to a fluorescent light, and are best used in areas where bright light is needed, such as in warehouses, car headlights, streetlamps, stadiums and factories.
Do xenon lights get hot?
Xenon light bulbs don’t produce as much heat, and emit minimal UV rays. This means they’re safer to use in fragile and high traffic applications. They’re also much more durable – oil doesn’t affect their performance, and they can even withstand unstable voltages.
How long does a xenon bulb last?
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.
What is the wavelength of xenon lamp?
The light produced by the xenon lamps includes broad-spectrum wavelengths from 100 to 1100 nm (Figure 1): UV light (100–400 nm), visible light (400–700 nm), and near-infrared light (700–1100 nm).
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 wavelength range of deuterium lamp?
The deuterium gas discharge lamp is a continuum radiation source for the 160–320 nm wavelength range.
How do you power a deuterium lamp?
Ignite and Operate Deuterium Lamps Deuterium lamps require filament power and anode-cathode voltage of at least 350 V to initiate the discharge and then, for best performance a carefully regulated discharge current. Until the deuterium lamp reaches thermal equilibrium, the radiated output varies.
Is xenon the same as HID?
HID is a type of light fixture that creates brighter light, and lasts longer, while Xenon is a subtype of HID that contains Xenon gas instead of the other alternatives.
Which is 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.
