1823 Johann Wolfgang Döbereiner invents the Döbereiner's lamp. 1835 James Bowman Lindsay demonstrates a light bulb based electric lighting system to the citizens of Dundee. 1841 Arc-lighting is used as experimental public lighting in Paris. 1853 Ignacy Łukasiewicz invents the modern kerosene lamp.
22 lis 2013 · In the 19th century, two Germans -- glassblower Heinrich Geissler and physician Julius Plücker -- discovered that they could produce light by removing almost all of the air from a long glass tube and passing an electrical current through it, an invention that became known as the Geissler tube.
Using lower current, a small carbonized filament, and an improved vacuum inside the globe, Edison successfully demonstrated the light bulb in 1879 and, as they say, the rest is history. Suffice it to say, light bulbs developed over a period of time.
Many teams and individuals have been involved with electric lighting technology during the past 120 years. Their collective efforts turned the marvel of electric lighting into a mundane part of our technical infrastructure–and in the process changed the way we live.
Eventually, with the discovery of electricity in the 18th century, we were able to bring brighter, safer lighting to buildings and outdoor areas. The progression of electric lighting technology from arc lamps to LEDs is a fascinating story with many international contributors.
