Arc Lamp (The first eletric light)
This is the first electrical lamp but for miners only. The safety lamp is very bright and it is not use for residential areas. The lamp works by electricity connect to a piece of charcoal, creating a bright spark and it burns out quicky. -
First Constant electric light is demonstrated
James Bowman Lindsay was the first to demonstrate a eletric light to the public of Scotland. The eletric light use eletrictiy consantly, to some people they say this was the first ever inventor of the incandescent light bulb. -
Geissler tubes
Two germans discoverd that eletric light could be produce by removing most of the air in a long tube then passing eletric currents through it, they called the tube the "Geissler Tube". -
Thomas Edison begin to work on Incandescent Lights
Thomas Edison begin to patent the Incandescent Lights, by first testing carbon, then platinumthen to a carbon filament. -
A New Lighting System
Thomas Edison proved that a centrally located generator can distribute power to a lighting system. -
Coloured Fluorescent Lights
Peter Cooper Hewitt created a fluorescent light that shows blue and green light by pasing electric current through mercury vapor. -
Incandescent Lamps with Tungsten Filaments
This was sold at the European market, these bulbs last longer then Thomas Edison's Incandescent light bulb. -
More Efficiency of Incandescent Light Bulb
Irving Langmuir discover that if he fill gases like nitrogen instead of sucking air out of the light bulb will increase the efficiency of the Incaandescent light bulb. -
Period: to
Fluorescent Light Bulb
European researchers were doing experiments with neon tubes coated with phosphors, then the United States begin research too. -
The First LED
Nick Holonyak, Jr. first created the LED -
Bendable Fluorrescent Tubes
Edward Hammer at General Electric figured out how to bend the fluorescent tube into a lot of shapes. -
Blue and White LEDs
The blue LED was created then shortly the white LED was made with blue, green, red LED lights. -
More Efficient Blue LEDs
Isamu Akasaki, Hiroshi Amano, Shuji Nakamura in Japan made a discovery on more enegry efficient Blue LED.
