What are near infrared LED?

What are near infrared LED?

What is Near Infrared? Near Infrared is a type of infrared light that falls just after red light on the electromagnetic spectrum. Its wavelengths span from 700nm – 1200nm and its light is invisible to the human eye.

Is near infrared light good for skin?

The right intensity of infrared light, which is determined by its wavelength and duration, may actually have a healing effect by increasing the cell renewal process and stimulating anti-inflammatory cytokines. Optimal wavelengths of infrared light may also have an anti-aging effect on the skin by stimulating collagen.

Is near infrared LED safe?

1). In healthy individuals, NIR light is mostly absorbed by blood pigments in deep tissue which does not heat up due to constant circulation. Hence, light in the NIR region does not present the risk of tissue damage that occurs at wavelengths longer than 950 nm which have been used for laser surgery [3].

What does near infrared light do?

NIR and LEDs light can activate photoreceptor cytochrome c oxidase, leading to elevated energy metabolism, increased wound healing, and inhibited toxicity (reviewed in 10). The applications of NIR light is to convert luminous energy into metabolic energy to modify biological functions of cells.

Is far infrared the same as red light therapy?

Red light is visible and is most effective for use on the surface of the skin. Red light occupies the “long end” of the visible spectrum with wavelengths of 630nm-700nm. Infrared light is invisible and is effective for use on the surface of the skin as well as penetration of about 1.5 inches into the body.

Is near infrared light harmful?

The most common eye disease associated with near-infrared radiation is cataracts. Prolonged exposure to IR radiation causes a gradual but irreversible opacity of the lens. Other forms of damage to the eye from IR exposure include scotoma, which is a loss of vision due to the damage to the retina.

Does Near Infrared penetrate clothes?

The near-infrared will penetrate clothing, barely, but each wavelength has a finite level of penetration. So, if it has to go through clothing first, it won’t penetrate as deeply into skin. So, the best bet is to have the red and near-infrared as close to bare skin as possible.

What is the difference between infrared and near infrared light?

Infrared light has a range of wavelengths, just like visible light has wavelengths that range from red light to violet. “Near infrared” light is closest in wavelength to visible light and “far infrared” is closer to the microwave region of the electromagnetic spectrum.

Is near infrared light the same as infrared?

Infrared Light (IR) is the light found just past what is visible to the human eye. Near-Infrared Light (NIR) is the section of electromagnetic radiation (EMR) wavelengths nearest to the normal range but just past what we can see.

What is near infrared light?

Near infrared light is in the range of 700nm-1400nm on the electromagnetic spectrum and has wavelengths that are longer than those of visible light, meaning that humans can’t see it. Infrared photography most commonly uses near infrared light.

What is a far infrared lamp?

Far infrared is part of the spectrum of light emanating from the sun. Far infrared is not visible to the eye, but you feel it as heat penetrating into your skin. You may be familiar with the infrared heat lamps sometimes used in bathrooms.

What are infrared LED lights?

An IR LED (infrared light emitting diode) is a solid state lighting (SSL) device that emits light in the infrared range of the electromagnetic radiation spectrum. IR LEDs allow for cheap, efficient production of infrared light, which is electromagnetic radiation in the 700 nm to 1mm range.

What is infrared security light?

An infrared security light should be used when you need to be covert, when you don’t want to let intruders know they are being watched. When repeated break-ins have occurred and nothing has been captured on video, the intruders may be skirting your cameras. A nearly invisible infrared security light will allow you to track the intruder’s
