  • Xenon Arc Lamp
    INSTRUMENTAL TECHNIQUE PRESENTATION Xenon arc lamp Madhuri Jash 01/08/2015 What is Xenon arc lamp? Xenon arc lamp is a gas discharge lamp where electric power is converted into light by an arc discharge in a xenon atmosphere at high pressure. Why we use xenon here because xenon has the highest overall conversion efficiency. History of arc lamp Carbon arc lamp was the first electric light invented by Humphry Davy in the early 1800s. This was the first widely-used and commercially successful form of electric lamp. 1875 Pavel Yablochkov had developed the Yablochkov Candle which was the first reliable carbon arc lamp and was used in Paris. 1870s-1890s Elihu Thomson and E.W. Rice Jr improved many parts of the arc light system both in DC and AC power. Then xenon short-arc lamps were invented in the 1940s in Germany and introduced in 1951 by Osram. First launched in the 2 kW size and now it is upto 15 kW. Xenon arc lamp construction .There is a fused quartz envelope with thoriated tungsten electrodes. Fused quartz is the only economically feasible material currently available that can withstand the high pressure. .the tungsten electrodes are welded to strips of pure molybdenum metal or Invar alloy, which are then melted into the quartz to form the envelope seal. .Because of the very high power levels involved, large lamps are water-cooled, An O- ring seals off the tube, so that the naked electrodes do not contact the water. .In order to achieve maximum efficiency, the xenon gas inside short-arc lamps is maintained at an extremely high pressure — up to 30 atmospheres — which poses safety concerns, large xenon short-arc lamps are normally shipped in protective shields.

Page 2 of 66 www.PDHcenter.com PDHonline Course E423 www.PDHonline.org Introduction Gas-discharge lamps are light sources that generate light by sending an electrical discharge through an ionized gas. The character of the gas discharge depends on the pressure of the gas as well as the frequency of the current. High-intensity discharge (HID) lighting provides the highest efficacy and longest service life of any lighting type. It can save 75%-90% of lighting energy when it replaces incandescent lighting. Figure 1 shows a typical high-intensity discharge lamp. In a high-intensity discharge lamp, electricity arcs between two electrodes, creating an intensely bright light. Usually a gas of mercury, sodium, or metal halide acts as the conductor. HID lamps use an electric arc to produce intense light. Like fluorescent lamps, they require ballasts. They also take up to 10 minutes to produce light when first turned on because the ballast needs time to establish the electric arc.

  • A Critical Comparison of Xenon Lamps
    TECHNICAL NOTE A Critical Comparison of Xenon Lamps Introduction When selecting a lamp as an excitation source for spectroscopic studies, the overall power produced by the lamp should not be the only parameter that is used for comparison of its effectiveness as an excitation source. Certainly, it is expected that a 450W lamp emits more light than e.g. a 300W lamp but this number alone does not guarantee that more light is available for exciting a sample. There are other factors such as the optics and geometry that play a role, but we will focus our attention only to the light source for now. Indeed, we will show that the 300W Cermax lamp mounted on ISS spectrofluorometers provides more usable intensity than the traditional 450W Xenon lamp mounted on other spectrofluorometers. Figure 1. Schematic drawing of the Cermax arc lamp and lamp housing in ISS spectrofluorometers. Spatial Light Distribution and Collection Optics A traditional 450W lamp is about 10 cm (4 inches) long; the bulb is filled with inert gas at about 75 atm. The lamp is usually mounted vertically, with the cathode below the anode. The light emitted by this lamp is concentrated in a donut-like shape around the plane perpendicular to the electrodes. The light distribution is asymmetrical: more light is emitted around the cathode than the anode. Roughly, the light extends in the lower plane of about 70° and in the upper plane about 50°. A lens (condenser) is placed in front of the lamp for the collection of light. Usually, a mirror is placed in the back to increase the amount of the light collected and directed forward: the use of the rear reflector 1 ISS TECHNICAL NOTE increases the total collected light by about 60%.

The difference is they have a small amount of halogen gas in with the inert gas. An incandescent lamp could have greater efficacy if run at a higher temperature The filament would evaporate faster and blacken the glass Introducing a halogen into the inert gas causes evaporated tungsten to bond with the halogen producing a halide When the halide approaches the hot filament the tungsten is released to the filament and the halogen is free to collect another tungsten atom The halogen cycle http://www.lamptech.co.uk/Movies/Halogen%20Cycle.WMV At higher filament temperature
