History of
LED Technology
The beginning - 1860
Niels Finsen, a Danish scientist, developed an artificial lamp that mimics sunlight. In 1903 he was awarded the Nobel Prize in Medicine for his study of the biological and therapeutic effects of light rays, and contributed greatly to the treatment of lupus (skin tuberculosis).
1928 - Invention of the RED LED
Nick Holonyak, an American scientist, invented the first red visible light LED as he continued research on visible light semiconductor lasers and light emitting diodes to develop a four-element compound semiconductor. Today, this technology is used in a variety of applications including medical diagnostic equipment, surgery, and ophthalmology
1971 - Invention of the GREEN LED
After the red LED was invented, the green LED was implemented from the Gallium Phosphide (GaP) p-n junction doped with nitrogen by Logan et al. Through this invention, technology can realize most colors that can be obtained in nature with light
1989 - Development of the BLUE LED
Nakamura, Akasaki and Amano succeeded in developing the first blue LED in Japan in 1989. With the development of blue LEDs, white LED production becomes possible, and LED development develops rapidly.
2000's - NASA
Expanded LED utilisation based on various effects researched by NASA and applicable to the medical field. While researching how to grow crops in spacecraft with artificial light sources, it was discovered that red LED wavelength promotes the energy metabolism of cells that activates plant growth and photosynthesis. It was also discovered that wound healing was accelerated due to skin cell regeneration.
