Whilst LEDs had been in use since the early 1960s as electronic components, with applications in remote control circuits, converting a pulse of current into a beam of infra-red light, and as indicator lamps for always-on appliances and in seven-segment displays, it was not until this day in 1996 when the Nichia Corporation, a Japanese chemical engineering and manufacturing concern, held a press-conference introducing brilliant white gallium nitride light-emitting diodes, after three years of experimentation and research,
that the semiconductor dim bulbs, only capable of shining in invisible wavelengths to low-intensity red, hinted at their potential as a commercial lighting alternative to an infrastructure built for energy-intensive incandescents. Despite skepticism over the viability of producing a prototype using conventional technology, Nichia supported the R&D efforts of Shuji Nakamura (ไธญๆ ไฟฎไบ, only given a token honorium for his invention, he later sued for a commensure share of the profits) whose experiments eventually netted not only the illusive white LED but also the blue laser diode in the process, the solid-state stylus for HD DVDs and Blu-Ray Discs. Incoherent and giving the illusion of pure colour saturation—like pixels and their subdivisions—LEDs produce light through electrolumininescence, the wavelength determined by the recombination of electrons and electron holes, the space of an atomic lattice where an ejected particle once was and in accordance with the shell-model could be replaced, over the gradient of the semiconductive circuit, pushing out a photon.
