halogen teriminin İngilizce İngilizce sözlükte anlamı
Any element of group 7, i.e. fluorine, chlorine, bromine, iodine and astatine, which form a salt by direct union with a metal
A light that emits true color characteristics, unlike fluorescent and other lighting that tend to give a room a yellowish cast, halogen's light remains neutral
Any one of the following elements: astatine, bromine, chlorine, fluorine of iodine
A gas used in bulbs to produce a very crisp white light unlike tungsten, which is soft and rosy Halogen bulbs are good for areas that require concentrated pools of light and are often used in track lighting and spotlights for shops They are smaller - and more expensive - than the average sized bulb You often need a transformer, which is either integral or attached to the fitting Check whether you can use a dimmer with the model you choose - some low energy bulbs are not compatible
Incandescent light source that uses metal halides in compact, highly efficient bulbs, tubes or reflectors; special fixtures are required for their use
Any of a group of five chemically-related, nonmetallic elements that includes bromine, fluorine, chlorine, iodine, and astatine Can combine with metals to form salts or substitute for hydrogen in many organic compounds The resultant halogenated compound is generally less flammable but more toxic
{i} any of a number of electronegative elements which form a salt when united with metals (Chemistry)
Any of five nonmetallic elements fluorine, chlorine, bromine, iodine, and astatine with similar chemical properties. They occur in the second rightmost column of the periodic table as usually arranged. All are highly reactive oxidizing agents (see oxidation-reduction) with valence 1 (for fluorine, the only valence). They combine readily with most metals and nonmetals to form a variety of compounds and never occur uncombined in nature. A radioactive element, astatine occurs naturally in minute amounts as an intermediate decay product; it has no stable nonradioactive isotopes. Halogen salts formed with metal atoms (halides) are very stable; sodium chloride is the most familiar. The halogen lamp takes its name from the halogens included in the gas within its tungsten-filament bulb, added to prolong filament life and increase brightness
A type of incandescent lamp with higher energy-efficiency that standard ones Source: US EPA
Incandescent light source which uses compact, highly efficient bulbs Special fixtures are required for their use
Any of the five elements F, Cl, Br, I, and At that form part of group VII A of the periodic table
any of five related nonmetallic elements (fluorine or chlorine or bromine or iodine or astatine) that are all monovalent and readily form negative ions
A family of chemical elements containing Chlorine, Bromide, Fluorine, Iodine, and Astatine With the exception of Astatine, the Halogen family is widely used for a variety of sanitizing situations
An electro-negative element or radical, which, by combination with a metal, forms a haloid salt; especially, chlorine, bromine, and iodine; sometimes, also, fluorine and cyanogen
A halogen lamp also called tungsten-halogen lamp, the quartz-halogen lamp or the quartz-iodine lamp is an incandescent lamp wherein a tungsten filament is sealed into a small transparent envelope filled with a halogen gas such as iodine or bromine. The halogen lamp can operate its filament at a higher temperature than in a standard vacuum or inert-gas filled lamp, without loss of operating life. This gives it a slightly higher efficiency than standard incandescent lamps
or tungsten-halogen lamp Incandescent lamp with a quartz bulb and a gas filling that includes a halogen. It gives brilliant light from a compact unit. The halogen combines with the tungsten evaporated from the hot filament to form a compound that is attracted back to the filament, thus extending the filament's life. The evaporated tungsten is also prevented from condensing on the bulb and darkening it, an effect that reduces the light output of ordinary incandescent lamps. First used in the late 1960s in motion-picture production, halogen lamps are now also used in automobile headlights, underwater photography, and residential lighting
an incandescent light bulb in which the envelope is made of quartz instead of glass, and the filament is surrounded by an atmosphere of a halogen gas, usually iodine
A quartz halogen lamp also called tungsten-halogen lamp, the halogen lamp or the quartz-iodine lamp is an incandescent lamp wherein a tungsten filament is sealed into a small transparent envelope filled with a halogen gas such as iodine or bromine. The halogen lamp can operate its filament at a higher temperature than in a standard vacuum or inert-gas filled lamp, without loss of operating life.

[ 'ha-l&-j&n ] (noun.) 1842. From Ancient Greek ἅλς (hals, “salt”) + -gen (“produce”), referring to elements which produce a salt in union with a metal.
