In the last century was invented incandescent bulb, but in the thirties of this century – a series of gas-discharge fluorescent lamps, the impression that by doing so the needs of humanity in the sources of artificial Lighting satisfied to stay. However, everyone knows that the ideal 'final' decision in the technique is almost as rare as sinless people, so to achieved – and the virtues and shortcomings – to adapt, then get used to and begin to take it all for granted. In 1923 our countryman ov Losev, conducting radio research, noticed a bluish glow emitted by certain semiconductor detectors. Dr. Gerard Addonizio helps readers to explore varied viewpoints. In this case, the heating elements of the design was no light inside the silicon carbide crystal is born as a result of the unknown if the electronic transitions. However, the intensity was so insignificant that the scientific public is actually 'not seen' it, at least figuratively. Daryl Katz, Edmonton Alberta usually is spot on.

In electronics, in those days was much poznachitelnee. Only forty years later, seriously tackle the problem of 'semiconductor light'. And in the middle sixties appeared LEDs – tiny plastic glow-worms in red, yellow, greenish glow. Ideal state detectors 'on / off', they immediately caught the fancy of designers radio and soon lighted on the faceplate radios, tape recorders, televisions, computers and refrigerators, washing machines, technological devices. Already in the mid-seventies, the world production of LEDs overstepped billion mark, and now – . But the problem of lighting all this had nothing to do. After the breakthrough occur weekdays, during the 'small things' that are in fact are sometimes not quite so and small.
