Infrared lamp tube (also known as infrared radiator) is a thermal radiation light source that uses electromagnetic waves to transfer heat for non-contact heating.
Its core structure is composed of tungsten wire and quartz tube, and it has the characteristics of rapid heating and cooling,
high thermal efficiency, and long service life. According to the temperature of the filament,
it can be divided into four forms: long wave, medium wave, fast medium wave, and short wave. Structurally, it can be divided into single tube and double tube.
