Lighting through the ages (legend)

Template:Timeline of lighting technology Artificial lighting technology began to be developed tens of thousands of years ago, and continues to be refined in the present day.

Antiquity

18th century

  • 1780 Aimé Argand invents central draught fixed oil lamp
  • 1784 Argand adds glass chimney to central draught lamp
  • 1792 William Murdoch begins experimenting with gas lighting and probably produced the first gas light in this year.

19th century

20th century

  • 1962 Nick Holonyak Jr. develops the first practical visible-spectrum light-emitting diode
  • 1981 Philips sells their first Compact Fluorescent Energy Saving Lamps, with integrated conventional ballast
  • 1985 Osram answers with the first electronic Energy Saving Lamps to be very successful [6]
  • 1986 The "White" SON Sodium vapor lamp is introduced.
  • 1991 Philips invents a fluorescent lightbulb that lasts 60,000 hours. The bulb uses magnetic induction.
  • 1992-94 a team at Nela Parc, Cleveland, GE, with Jack Strok creates ceramic metal halide lamps (CMH). Philips follows under W.de Kock and calls their versions CDM Ceramic Discharge Metal. Sales begin 1994. This technology improves to be the superior lighting technology with up to 150 lm/W with good color rendering and 20.000h life at very high lumen maintenance [4]
  • 1994 the new T5 lamps with cool tip are introduced to become the leading fluorescent lamps with up to 117 lm/W with good color rendering. These and almoast all new fluorescent lamps are to be operated at electronic ballasts only.[7]
  • 1994 First commercial sulfur lamp.
  • 1995 Shuji Nakamura at Nichia labs invents first blue and, with additional Phosphor, white LED, and starts a LED boom.[8]

21st century

  • 2011 Philips wins L Prize for LED screw-in lamp equivalent to 60W incandescent A-lamp for general use.
