Beginning of Light Therapy

He was the Danish medical practitioner who greatly contributed to the treatment of lupus (skin tuberculosis) by developing an artificial lamp that mimics the sun’s light and studying the biological and therapeutic effects of light rays. His studies paved the way for the beginnings of the Light Therapy.

Discovery of Low `Power Phototherapy

He was the Hungarian doctor who discovered the effect of a low-power laser on wound healing, fibromyalgia, etc., while conducting experiments with a red low-power laser. Since then, he treated skin ulcer patients and wrote over 100 papers, paving the way for the beginnings of low-power phototherapy. He has come to be regarded as the father of light bioregulation.

Discovery of Red LED

He was the American scientist who invented the first red visible-light LED and continued research on visible-light semiconductor lasers and light-emitting diodes to develop a four-element compound semiconductor. Today, his technology is being used in a variety of applications, including medical diagnostic equipment, surgery, and ophthalmology.

Realization of Green LED

After the red LED was invented, a green LED was realized from the gap p-n junction with nitrogen added by Logan, et al. Through this, we have secured the technology to realize most of the colors that can be obtained from nature with light.

Discovery of Blue LED

He was the Japanese professor who created the basis for the blue semiconductor laser after developing the first blue LED. He continued to develop blue LEDs and won a Nobel Prize in Physics in 2014.

LED utilization that was expanded from NASA to the medical field based on its various effects

While researching how to grow crops in a spacecraft with artificial light sources, it discovered the fact that the red LED wavelength promotes energy metabolism in cells, which activates plant growth and photosynthesis, and that irradiating LEDs of a specific wavelength doubles cell growth, which accelerates the healing of wounds. This led to research on LED as a medical technology that helps skin cells regenerate, which paved the way for its utilization in various medical fields.
