A xenon arc lamp is a highly specialized type of gas discharge lamp, an electric light that produces light by passing electricity through ionized xenon gas at high pressure. It produces a bright white light to simulate sunlight , with applications in movie projectors in theaters , in searchlights , and for specialized uses in industry and research.
Xenon lamp may refer to: Xenon arc lamp; Xenon flash lamp; An incandescent light bulb filled with xenon gas to improve life span or efficiency; A metal halide lamp that is used in automotive headlights
Xenon short-arc lamps; The light-producing element of these lamp types is a well-stabilized arc discharge contained within a refractory envelope arc tube with wall loading in excess of 3 watts per square centimetre (19 W/in 2). Mercury-vapor lamps were the first commercially available HID lamps.
Xenon has been used as a general anesthetic, but it is more expensive than conventional anesthetics. [154] Xenon interacts with many different receptors and ion channels, and like many theoretically multi-modal inhalation anesthetics, these interactions are likely complementary. Xenon is a high-affinity glycine-site NMDA receptor antagonist. [155]
As the duration of the flash that is emitted by a xenon flashtube can be accurately controlled, and due to the high intensity of the light, xenon flashtubes are commonly used as photographic strobe lights. Xenon flashtubes are also used in very high-speed or "stop-motion" photography, which was pioneered by Harold Edgerton in the 1930s.
A krypton long arc lamp (top) is shown above a xenon flashtube. The two lamps, used for laser pumping , are very different in the shape of the electrodes, in particular, the cathode (on the left). An arc lamp or arc light is a lamp that produces light by an electric arc (also called a voltaic arc).
