Far infrared zone 30 1000 microns.
Infrared is the most powerful of all sunlight rays that penetrate deep into the subcutaneous tissues. Because the vibration frequency of far infrared rays is close to the vibration frequency of cells and molecules in the human body, after the "life light wave" penetrates into the body, it will cause the resonance of atoms and molecules of human cells, through resonance absorption, friction between molecules to form a thermal reaction, promote the temperature of the deep subcutaneous layer, and make the microvasculars dilate, accelerate blood circulation, is conducive to the removal of vascular hoards and harmful substances in the body, will hinder the removal of metabolic obstacles, re-resurrect tissues, promote enzyme production, activate tissue cells, prevent aging, The purpose of strengthening the immune system. Therefore, far infrared rays can improve and prevent a variety of diseases caused by blood circulation and microcirculation disorders.
In addition, some harmful substances in the human body, such as heavy metals and other toxic substances in food, lactic acid, free fatty acids, fat and subcutaneous fat, sodium ions, uric acid, cosmetic residues accumulated in the pores, etc., can be metabolized without passing through the kidneys, directly discharged from ** and sweat, which can avoid increasing the burden on the kidneys.
Therefore, because the function of far infrared rays is what the human body needs, plus the infrared heating lamp has some visible red light, I estimate that the wavelength of the infrared heating lamp is in the range of microns to 1000 microns.

Near-infrared: refers to infrared light with wavelengths ranging from to.
Infrared light refers to light with wavelengths ranging from 500 m, which can be subdivided into three regions: near-infrared, mid-infrared, and far-infrared.
Near-infrared: refers to infrared light with wavelengths ranging from to.
Mid-infrared: refers to infrared light with wavelengths ranging from 25 m, which is the most useful and information-rich area for molecular structure analysis.
Far infrared: refers to infrared light with wavelengths ranging from 25 m to 500 m.

LED lamps emit light of any color, from infrared to ultraviolet.
The luminous color and luminous efficiency of LED are related to the materials and manufacturing processes of making LEDs, and there are three widely used types: red, green and blue. Due to the low working voltage of Ledimei LED (only, it can actively emit light and has a certain brightness, and the brightness can be adjusted by voltage (or current), and it is also shock-resistant, vibration-resistant, and has a long life (100,000 hours). Depending on the material used to make LEDs, photons with different energies can be generated, which can control the wavelength, also known as the spectrum or color, of the light emitted by the LEDs.
The material used in the first LED in history was arsenic (AS) gallium (Ga), and its forward PN junction voltage drop (VF, which can be understood as the lighting or operating voltage) is, and the light emitted is the infrared spectrum. Another commonly used LED material is gallium phosphide (P) (Ga), which emits green light due to a forward PN junction voltage drop.
Infrared wavelength: greater than 800nm
The red wavelengths are: 620 630nm;
The orange wavelength is: 600 620 nm;
Yellow wavelengths: 585-600 nm;
The green wavelength is: 555 585 nm;
The blue wavelength is: 440-480nm
Violet wavelength: 350-440nm
Pink wavelength: 360-380nm
Ultraviolet light: less than 350nm
And so on, from red to purple, the wavelength decreases sequentially, and the energy decreases sequentially.

LED lamps emit different wavelengths of light due to the different metal elements added to the diode wafer manufacturing process and the different proportions of their composition. The wavelength is 470 blue light, 530 green light, 570 yellow light, and 630 red light. The special metals of blue and green light need to grow on sapphire in the wafer epitax, so every blue-green LED chip is made of sapphire.

Fluorescent lamps are not lamps in the all-visible spectrum.
The fluorescent lamp relies on the mercury atoms of the lamp to release ultraviolet light (the main wavelength is 2537 angstroms = 2537*10-10 m) through the process of gas discharge, and the fluorescent material on the inner surface of the lamp absorbs the ultraviolet light and releases visible light. Different fluorescent substances emit different visible light. The phosphor of a general fluorescent lamp uses the distribution of light emitted by different types of lamps with three-wavelength phosphor.
Rare earth phosphors are used to combine the three narrow spectra of blue (452nm), green (543nm) and red (611nm) into white light. The detailed spectral distribution is as follows:
To put it simply, there are three wavelengths: 452nm, 533nm, and 611nm (the specific value comes from the Internet).

Basically, in the visible light range, that is, from 400nm to 750nm, the energy of each band is different, so that the luminescence color is different, that is, the color temperature is different.
In the vicinity of fluorescent tubes, some are long ultraviolet (365nm), as well as infrared. Because the radiation at these wavelengths is weak, it is absorbed by the air over a certain distance.
The infrared rays of fluorescent lamps are mainly caused by the temperature of the filament when emitting electrons, the collision of electrons with mercury atoms, and the heat generated when ultraviolet light hits phosphors.
Most of these infrared wavelengths are in the near-infrared range of 750nm to 1000nm. A few in the intermediate infrared range of 1000nm to 4000nm. There are also trace amounts of 4000nm to 14000nm in the so-called "life ray" segment.
The far-infrared wavelength should reach 1000000nm, which is 1mm (millimeter). If it's longer, it's microwave.
In the tube of the fluorescent lamp, there are ultraviolet rays such as 185nm and 254nm, which are absorbed by phosphor and glass.

One possibility is that the bulb is made of red glass, or that the inner and outer layers of the glass are coated with some kind of red paint.
Infrared bulb is a kind of reflective lamp, infrared bulb wavelength range, peak wavelength 4 m, belongs to short and medium wave, can accurately control the radiation of energy, hard glass mechanical thermal strength, can resist sudden cooling and water sputtering. The ignition point of infrared heat lamps depends on their outer blister shell: there is no restriction on the ignition point position of lamps with transparent housings.
For red-coated lamps, the position is that the head of the lamp is facing upwards and the deviation is within 45 degrees.

Well, it may be that the light bulb is impure and therefore carries light waves similar to its wavelength, and infrared rays are invisible.

In layman's terms, a thermal imaging camera is the transformation of the invisible infrared energy emitted by an object into a visible thermal image. The different colors on the top of the thermal image represent the different temperatures of the object being measured. By viewing the thermal image, the overall temperature distribution of the measured target can be observed, and the heating situation of the target can be studied, which provides a basis for judgment for work and research. >>>More
