Encyclopedia > Ceramic Discharge Metal Halide lamp
Ceramic Discharge Metal Halide lamps are a relativly new source of light that is a variation of the Mercury-vapor lamp. There is a ceramic tube inside the lamp that heats a Mercury-Argon mixture creating a blueish light that is close to daylight with a color index of 96. They are five times brighter than comperable Tungsten sources. A Mercury-vapor lamp is a gas discharge lamp which uses mercury in an excited state to produce light. ... Look up Mercury in Wiktionary, the free dictionary Mercury may mean: Science Mercury (planet), the nearest planet to the Sun in the solar system. ... General Name, Symbol, Number argon, Ar, 18 Chemical series noble gases Group, Period, Block 18, 3, p Appearance colorless Atomic mass 39. ... General Name, Symbol, Number tungsten, W, 74 Chemical series transition metals Group, Period, Block 6, 6, d Appearance grayish white, lustrous Atomic mass 183. ...
Applications for these lamps include television and film making as well as digital photography and architectural lighting.
In the metalhalidelamp of another aspect, a translucent tube is disposed in the outer tube, and the discharge tube and the proximity conductor are disposed in the translucent tube.
Hereafter, according to this discharge, temperatures on the inner walls of the discharge tube 4 are increased, and thereby, the metalhalide is vapored.
In this lighting test, the metalhalidelamp of the present embodiment was lit by a use of a stabilizer of 150 W in which an igniter output the pulse voltage having a maximum pulse voltage (a peak voltage) of 2.5 kV and a pulse width of 0.5.mu.
The angular dimension of the cone of light from reflectorized lamps (such as R and PAR types) encompassing the central part of the beam out to the angle where the intensity is 50% of maximum.
A halogen lamp is an incandescent lamp with a filament that is surrounded by halogen gases, such as iodine or bromine.
A high-intensity discharge light source in which the light is produced by the radiation from mercury, plus halides of metals such as sodium, scandium, indium and dysprosium.
