How infrared lamps work

The infrared lamp is constructed by projecting a tungsten wire into an inflated quartz tube. The tungsten wire generates heat under the action of an alternating voltage and heats the gas in the quartz tube, thereby generating infrared electromagnetic waves. The infrared rays radiate outward and can be used for heating.

Quartz near-infrared, far-infrared using transparent or translucent quartz glass as the lamp envelope can produce near-infrared or far-infrared radiation spectrum. Infrared is an electromagnetic wave that propagates at the speed of light and carries a high amount of energy. The infrared intensity of different types of infrared rays of the same power differs from the wavelength and the intensity is different.

A, long-wave infrared (ie far-infrared) features: fast heating rate, uniform heating, small thermal inertia, only 1-3 minutes to reach the constant temperature of the component, high energy radiation conversion efficiency of 60%-75%, hot and cold does not burst , energy saving and long service life.

B. Short-wave infrared (ie, near-infrared) Features: It has a heating and cooling time of 1-3 seconds, which makes the heating process control more flexible. The efficient and durable gold-coated reflective layer of single tube and concrete tube can achieve more than 96% radiation efficiency and long service life, generally more than 10,000 hours. It is especially widely used for drying and curing of high-speed printing equipment. It can quickly heat the surface of objects with plastics, water and other solvents, and has the characteristics of being quickly absorbed by the water film to achieve the drying effect. Such as Heidelberg, Roland, Komori, Li Youbi and other offset printing machines; Mai Andi, Jielas, Yajiafa, and other flexographic printing machines; hardcover books and magazines linked production line equipment, such as Martini, Kolbus hardcover linkage Line and so on.
