The blue LED was supposed to be impossible—until a young engineer proposed a moonshot idea.

    Shuji Nakamura was a researcher at Nichia who was determined to create the first blue LED, which had eluded scientists for decades. Through innovative crystal growth techniques and materials discoveries, he succeeded in developing bright blue and white LEDs in the early 1990s. This breakthrough enabled LEDs to be used for full-spectrum lighting. Nichia’s fortunes grew enormously as a result, though Nakamura was not properly compensated for his invention. Today, LEDs powered by Nakamura’s blue LED technology are ubiquitous and have brought enormous energy savings worldwide.

    Something interesting I found was that Nakamura persisted in his research for blue LEDs against the wishes of his company management, who saw it as a waste of resources. His stubbornness and belief in his work paid off by solving a problem that had stumped the electronics industry for 30 years.

      full-spectrum lighting

      this doesn’t sound true.

      iirc full spectrum means “every wavelength” (like sunlight) and not just “3 wavelengths that add up to white”.
