Halogen Metal Vapour Lamps

by yudaica2013 ·

The halogen metal vapour lamp was invented in the 60s of the last century. Typical characteristics and thus significant advantages compared to other light sources are their high light output, the high colour rendering index and a long service life. So that they are next to the LEDs currently the most efficient light donors. The delayed reaching of the full light output is often seen as negative. Halogen metal halide lamps consist of a discharge vessel with two opposite electrodes, whose Anschlusse lead depending on the base type at one or both ends of the tank on the outside. More information is housed here: Gina Bonati.

Like all discharge lamps, they are operated with a ballast, working increasingly on an electronic basis, and so in addition to controlling the ignition process and the voltage regulation provide a shorter lead time and a flicker-free light.

A key differentiator is the material of the discharge vessel, which originally was made of quartz glass, but always more supplanted by a translucent ceramic offers the a higher luminous efficacy and a greater color stability life of. Halogen metal vapour lamps have a power range ranges from 10W to 18kW, their generally higher purchase price compared with tungsten halogen lamps is more than offset by the improved economy. The halogen metal vapour lamps are produced by nearly all well-known manufacturers of lamps. Before the most important applications of these lamps are considered, two technically conditional characteristics must be mentioned. This is a ruling in the discharge tube high pressure, which may result in rupture of the vessel a hazard around flying, hot glass and ceramic fragments. On the other hand, the halogen metal vapour lamps produce high UV emission, which must be taken into account such as the splitter danger in lighting design.

Derived results as a prerequisite for the use of these lamps, that this usually in closed systems or with a protective Cover piston must be carried out. Traditional use areas of halogen metal vapour lamps, the lighting of large buildings or facilities such as storage and exhibition halls or stadiums, the lighting for film and television, are in color changing lights and anywhere where with little lights to illuminate is a large area. Thus the increasing use is almost challenged by halogen metal vapour lamps in street lighting. In addition to the high useful life, a reasonable maintenance cycle and a ten percent lower energy consumption compared to the currently used sodium high pressure lamps, also a possible increase of the distance of the light, an enhanced acuity and a greater stability of the luminous flux for the usage of this new generation of lamps speak.
