De uitvinding van de gloeilamp

Period: Jan 1, 1800 to Jan 1, 1995

de ontwikkeling van de gloeilamp mede door Edison. Alleen de jaartallen gelden! dus niet de dagen en maanden.

platinadraad expirimenten

Aug 29, 1801

In 1801 experimenteerde Humphry Davy al met een gloeiende platinadraad, die echter onmiddellijk verbrandde.

Elektrisch licht

Oct 29, 1809

1809 - Humphry Davy, an English chemist, invented the first electric light. Davy connected two wires to a battery and attached a charcoal strip between the other ends of the wires. The charged carbon glowed making the first arc lamp.

lamp design

Oct 29, 1820

1820 - Warren De la Rue enclosed a platinum coil in an evacuated tube and passed an electric current through it. His lamp design was worked but the cost of the precious metal platinum made this an impossible invention for wide-spread use.

prototype gloeilamp

Oct 29, 1835

1835 - James Bowman Lindsay demonstrated constant electric lighting system using a prototype lightbulb.

Oct 29, 1850

1850 - Edward Shepard invented an electrical incandescent arc lamp using a charcoal filament. Joseph Wilson Swan (on the picture) started working with carbonized paper filaments the same year.

uitvinding gloeilamp

Oct 29, 1854

1854 - Heinrich Göbel, a German watchmaker, invented the first true lightbulb. He used a carbonized bamboo filament placed inside a glass bulb.

vacuum pomp

Oct 29, 1875

1875 - Herman Sprengel invented the mercury vacuum pump making it possible to develop a practical electric light bulb. Making a really good vacuum inside the bulb possible.

patent gloeilamp

Oct 29, 1875

1875 - Henry Woodward (picture) and Matthew Evans patented a lightbulb.

gloeilamp 13,5u

Oct 29, 1878

1878 - Sir Joseph Wilson Swan (1828-1914), an English physicist, was the first person to invent a practical and longer-lasting electic lightbulb (13.5 hours). Swan used a carbon fiber filament derived from cotton.

gloeilamp 40u

Oct 29, 1879

1879 - Thomas Alva Edison invented a carbon filament that burned for forty hours. Edison placed his filament in an oxygenless bulb. (Edison evolved his designs for the lightbulb based on the 1875 patent he purchased from inventors, Henry Woodward and Matthew Evans.)

gloeilamp 1200+ u

Oct 30, 1880

1880 - Edison continued to improved his lightbulb until it could last for over 1200 hours using a bamboo-derived filament.

nieuwe gloeidraad

Oct 30, 1903

1903 - Willis Whitnew invented a filament that would not make the inside of a lightbulb turn dark. It was a metal-coated carbon filament (a predecessor to the tungsten filament).

patent wolfraam filament

Oct 30, 1906

1906 - The General Electric Company were the first to patent a method of making tungsten filaments for use in incandesent lightbulbs. The filaments were costly.

verbeterde methode woflraam filamenten

Oct 30, 1910

1910 - William David Coolidge (1873-1975) invented an improved method of making tungsten filaments. The tungsten filament outlasted all other types of filaments and Coolidge made the costs practical.

matte gloeilampen

Oct 30, 1925

1925 - The first frosted lightbulbs were produced.

De dood van Edison

Oct 30, 1931

Edisons death

gloeilamp 60,000+ u

Oct 30, 1991

1991 - Philips invented a lightbulb that lasts 60,000 hours. The bulb uses magnetic induction.’
