Halogen lamp generally refers to halogen bulb.Halogen bulbs (English: halogen lamp), referred to as halogen bulbs or halogen lamps, also known as tungsten-halogen bulbs .Quartz bulb, a variant of the incandescent lamp.Halogen lamps are made with a tungsten filament, but are encased in a much smaller quartz glass shell.Because the glass case is so close to the filament, it would easily melt if it were made of glass.

What is a halogen lamp

I.In fact, the filament and the glass housing of this lamp are filled with halogen elements such as iodine and bromine.As the filament heats up, the tungsten atoms are evaporated and move towards the glass tube wall.Tungsten bromide).The tungsten halide moves towards the center of the glass tube and falls back onto the corroded filament.Because tungsten halide is very unstable, it decomposes into halogen vapor and tungsten when exposed to heat, so that the tungsten is deposited on the filament again, making up for the evaporated part.In this cycle, the filament lasts much longer.Halogen bulbs (Halogenlamp), also known as tungsten-halogen bulbs, are a type of incandescent lamp.The principle is to inject a halogen gas such as iodine or bromine into the bulb. At high temperatures, the sublimated tungsten filament interacts chemically with the halogen, and the cooled tungsten will re-consolidate on the tungsten filament, creating a balanced cycle that prevents premature breakage.Thus halogen bulbs last longer than incandescent lamps.ii.Characteristics of Halogen Lamps Halogen lamps are made with a tungsten filament, but are encased in a much smaller quartz glass shell.Because the glass shell is so close to the filament, if it were made of glass it would melt easily.The gas inside the glass shell consists of different gases that make up the halogen lamp set.These gases have a very interesting property: they combine with tungsten vapour.If the temperature is not high enough, the tungsten atoms bound to the halogen gases evaporate and are redeposited on the filament.This cyclic process makes the filament last a lot of time.In addition, it can run the filament hot, which means you get more light energy.You still get a lot of heat, but because the glass housing of the quartz is so close to the filament, it is hotter compared to a normal bulb.Halogen bulbs can also operate at higher temperatures than normal incandescent bulbs, and they are brighter and more efficient.At these temperatures, however, ordinary glass may soften, so halogen bulbs require quartz glass with a higher melting point.Since quartz glass does not block UV light, halogen bulbs usually require a separate UV filter.If the crystal glass on a halogen bulb has oil in it, the temperature on the glass will vary, reducing the life of the bulb.Therefore, when changing halogen bulbs, avoid touching the glass of the bulb by hand.If you touch it with your fingers, clean it with alcohol.
