When did the LED light source start to be used in the medical field?
LED light source is a new type of light source in the laser family, which belongs to the "weak laser" category, and is considered to be one of the most ideal medical light sources for human beings in the future. The LED light source itself does not contain harmful substances such as mercury and lead, and has no infrared and ultraviolet pollution, and will not cause external pollution during use.
LED is called light-emitting diode, or LED for short. It is a solid-state semiconductor device that can convert electrical energy into visible light. It has been widely used in traffic lights and large-area display screens, and has produced good economic and social benefits.
Because the LED light source has many advantages such as high light efficiency, high light quality, pure light color, stable performance, low energy consumption, long life, no safety hazard, and convenient use, it also has the same light penetration characteristics and biological characteristics of the laser light source. Stimulating effect, so it is also applied in clinical medicine.
In the early 1990s, the US National Aeronautics and Space Administration (NASA) applied LEDs to the space station for the first time to regulate the body of astronauts. When astronauts are in space, due to the disappearance of the earth's gravity environment, various parts of the human body without the effect of earth's gravity will cause so-called "space sickness" symptoms, such as muscle atrophy, osteoporosis of the lower limbs, blocked blood circulation, and decreased immune function. Body irradiation with doses of red light of appropriate wavelengths can restore normal physical performance. Later, the clinical application of LED was extended to photodynamic therapy of tumors, elimination of skin inflammation and ulcers, promotion of wound healing, facial rejuvenation, wrinkle removal, freckle removal, and acne treatment. There are foreign media reports: LED red light is a new revolution in light therapy, even replacing laser and IPL strong light.
After the era entered the 21st century, more and more attention was paid to the medical application of LED light sources. Laser medical experts from the United States, the United Kingdom, Germany, Japan, Israel, Italy, Russia and other countries began to successfully use LED medical equipment on the basis of research The development of miniaturized and portable instruments has promoted LED light therapy into the public family, enabling technology to stimulate the "light of health" to illuminate more ordinary people.
