In our impression, LED light sources are mainly used for light box lighting, decorative lighting, sign lighting, etc., but they are less used in medical and cosmetic applications. With the continuous development of LEDs, people are also deeply concerned about the wavelength characteristics of LED light sources. Research, the characteristics of wavelengths have also achieved remarkable applications. The following is a brief understanding of the characteristics of several different wavelength light sources.

Ultraviolet light: The wavelength selection range of ultraviolet LED is 311nm~400nm, the wavelength is 20nm~30nm, and the power of LED light source is several milliwatts to several hundred milliwatts. UVA can treat skin diseases such as psoriasis, and can also be used for beauty, sterilization, etc.

Infrared light: LED infrared chips are suitable for the manufacture of near-red light devices, and IR LEDs in the range of 780nm to 1200nm can be selected for anti-inflammatory, analgesic and metabolism promotion.

Blue light: LED light source in the range of 425nm ~ 475nm, which can be used to treat neonatal jaundice, etc. The 446nm-477nm LED light source can promote the secretion of the pineal amine hormone-melatonin that regulates the biological cycle of the human body, and is conducive to enhancing the vitality of the human brain. For example, encapsulating blue LEDs in a blanket-like baby quilt could eliminate the need for goggles to protect the eyes when treating neonatal jaundice.

Red light: Red light LED light source can be used in the range of 615nm ~ 700nm, the light color is pure, red light can promote cell synthesis, promote wound healing, and treat various diseases through photochemical action.

Mixed light and white light: White light or several different wavelength LEDs are mixed in the same package to form yellow-green light, violet light and blue-green mixed light, etc., which can meet different treatment needs. White light irradiation with different color temperatures can be used for insomnia adjustment therapy.

At present, the convenience of medical application is more prominent, and the use of LED light sources for blue light, red light, near-infrared light, ultraviolet light, and multi-color mixed light phototherapy has achieved obvious clinical effects. Relevant institutions in developed countries such as Europe, America and Japan have launched various phototherapy equipment using LED light sources, and many domestic achievements have also been made in this field. In the future, there will be more LED scientific research products to serve our healthy life.

The above is the application of LED light source in medical beauty. If you need to know more detailed information about LED light source, please consult Shenzhen SUNLITE Optoelectronics Co., Ltd.
