Infrared lamps, also known as infrared heating lamps, are lamps whose main component of radiation is in the infrared spectral range. Infrared lamps can provide energy radiation that can be precisely controlled, can be used for heating, industrial applications in the semiconductor industry in the hot electronic wafers, blowing PETP bottles, reflow soldering equipment, drying filler, motor vehicle repairs in the drying of paint, medical applications in the photocopying machine colorant positioning, the melting of the solder on the bottom of the printed circuit board, food heating and sterilization and so on. Infrared lamps are widely used in machinery, automotive, food, medical and other industries.
Principle of infrared bulb:
The principle is very simple, metal at high temperatures will be emitted to the outside world of electromagnetic waves, light is a kind of electromagnetic waves, and infrared is also a kind of electromagnetic waves, only it has to be in the frequency of red light wavelengths other than that, so it is known as infrared, which is also a kind of electromagnetic waves, as long as the choice of high temperatures can only be emitted in infrared wavelengths of infrared electromagnetic waves should be able to produce infrared. The infrared light is produced.
