Hydrargyrum medium-arc iodide, or HMI®, is a mercury-halide gas discharge medium arc-length lamp with a multi-line spectra emission. The name implies that hydrargyrum, an archaic term for Mercury(Hg), is held as a vapour mixed with other rare halides in a quartz-glass envelope with two tungsten-coated electrodes of medium arc separation. Unlike traditional tungsten lighting units, HMI(R) s use ballasts to regulate and supply electricity to the lamp head via a header cable. The lamp operates not by heating a tungsten-based filament, but rather by creating an electrical arc between two electrodes within the bulb that excites the pressurized mercury vapour and provides phenomenal light output with greater efficiency than tungsten-based lighting units. 3, record 1, English, - hydrargyrum%20medium%2Darc%20iodide%20technology

History: In the late 1960s German television producers sought out lamp developer OSRAM to create a less expensive replacement for incandescent lights for the film industry. Osram developed and began producing HMI® bulbs at their request. 3, record 1, English, - hydrargyrum%20medium%2Darc%20iodide%20technology

Une lampe aux halogénures métalliques ou lampe à décharge à haute pression est une lampe très utilisée pour l'éclairage lors de la prise de vue au cinéma, ainsi que dans les vidéoprojecteurs de forte puissance. Moins courantes en éclairage théâtral, elles envahissent l'éclairage public car leur couleur plaît. On les utilise surtout pour les terrains sportifs, comme les terrains de tennis, badminton, football, hockey, etc. Elles sont aussi très utilisées dans les gymnases et [les] terrains intérieurs. On peut également s'en servir pour éclairer les stationnements, les chantiers de construction et même les routes, en particulier les ponts. Certaines d'entre elles sont connues sous le nom de HMI, acronyme de l'expression allemande «Hydrargyrum mittlere bogenlänge Iod» (traduit en anglais par : «Hydrargyrum medium-arc iodide»), marque déposée de la firme allemande Osram, mais d'autres dénominations existent pour cette même catégorie de lampes, chez Osram (HMP, HTI, HSR par exemple) et chez d'autres constructeurs (MSR, MSD, MSI chez Philips). 3, record 1, French, - technologie%20HMI

The three way lamp has four switch positions : off, filament 1 on, filament 2 on, and both filaments on. The bulb has three electrical connections to its filaments. One contact delivers electrical power to filament 1, another contact delivers electrical power to filament 2, and the third contact returns electricity from both filaments to the power plant. The switch carefully controls the flow of electricity to the two filaments so that at the low light setting, only the small filament is on, at the medium setting, only the large filament is on, and at the high setting, both filaments are on. 2, record 3, English, - three%2Dway%20lamp
