What is Infrared radiation？

Infrared radiation is a form of electromagnetic energy that is generated by the vibration and rotation of atoms and molecules within all objects with temperatures above absolute zero (0° Kelvin; -459° F; or -273° C). Infrared (literally meaning "below" or "beyond" the red) is located between the visible and microwave portions of the electromagnetic spectrum and shares many of the same properties of visible light, except it has a longer wavelength. When infrared waves encounter a solid object they can be reflected (bounce off), diffracted (scattered), refracted (bent), transmitted (pass through), or absorbed by the object where several of these effects can take place at the same time. The visible portion of the spectrum ranges in wavelength from 0.38 microns to 0.76 microns. The infrared portion, which is not visible to the human eye, begins at 0.76 microns and extends to 10.0 microns (micron = one thousandth of a millimeter, one millionth of a kilometer). All objects emit infrared as a function of their temperature.

How infrared radiation work？

All materials absorb a fraction of the infrared spectrum,reflect a fraction at the surface and allow a fraction of the radiation to pass through. By selecting emitter with suitable spectra,the largest possible fraction of the radiation is absorbed in the material and converted into heat.

Infrared heat lamp heat the person or the objects near it by infrared radiation directly within a short time, and the person will feel warm and the objects will turn hotter sonn, Quickly heat lamps heat the object directly but don’t heat the surrounding air which is the reason why it can make highly efficient heating source, Further more, infrared heat lamps heat up the object penetrates into the object don’t just act on the surface. The lamps can be controlled quickly and easily.

Depending on the temperature of the heating element,an infrared emitter delivers distinctly different radiation at various wavelengths.

To achieve successful process heating, it is important that the infrared emitter is carefully matched to the properties of the product to be heated in terms of its wavelength, its shape and its power output. Radiation which precisely matches the absorption characteristics of the product is quickly converted into heat in the product,without unnecessary heat being transferred to the surroundings.

Short wave radiation can penetrate deep into some solid materials and ensure a uniform through heating.

Medium wave radiation is absorbed mostly in the outer surface and predominantly heats the surface. Medium wave radiation is particularly well absorbed by many plastics.glass and especially water and is converted directly into heat.
