Why Buy LED's?
Light Emitting Diodes(LED's) represent a revolution in lighting efficiency and output that provides an opportunity to improve the built environment and save energy. LED retrofit lamps are readily available from us for most incandescent or fluorescent lighting bases, see our Bases Section to identify your base type to be replaced.
The History of LED
Since 1960, Dr Nick Holonyak of General Electric was developing an unusual material – GaAsp, as a route to wide band gap tunnel diodes.
In 1907, the Englishman Henry Joseph Round had discovered Electroluminescence, by which materials can light up when electricity applied.
In 1961, first modern LED was invented by Bob Biard and Gary Pittman, which was discovered by ‘accident’ while they were trying to make a laser diode, during the GaAs test.
During the following year, Mr Nick Holonyack Jr. developed the red LED. Till 1979, the coloured LEDs were developed. During this period, a Franch Thomas P. Pearsall developed special high brightness LEDs for fiber use.
