Solid state lighting:
What is solid state lighting?
Todays lamps are predominantly incandescent light bulbs and fluorescent tubes. For radios and TVs semiconductor electronics has long ago replaced vacuum tubes - for lighting the replacement of glas tubes by semiconductors has not been possible until recent breakthroughs in semiconductor technology in the 1990s. Solid state lighting uses GaN based light emitting diodes (LEDs) or organic light emitting diodes (OLEDs) as lamps.
Why does it make sense to replace fluorescent tubes and incandescent lamps with GaN based LED lamps?
GaN based LEDs have much longer life, consume far less energy, and are less environmentally harmful than both fluorescent tubes, and incandescent lamps.
Who invented GaN based white LEDs?
Shuji Nakamura developed the first commercially viable white LEDs based on GaN at Nichia Chemical Industries in Anan (Shikoku, Japan). His work continued and expanded previous work by Isamu Akasaki (at Nagoya University) and Jacques Pankove (at RCA Labs in the 1970s).
