Alt til hus og bolig Når kom det første gang lyspærer med E27 og/eller E14 sokkel?

Det lurer jeg på, her jeg sitter i lyset av moderne LED pærer med E14 sokkel.

Edison screw (ES) is a standard socket for light bulbs. It was developed by Thomas Edison and was licensed in 1909 under the Mazda trademark. Normally, the bulbs have right-hand threadedmetal bases (caps) which screw into matching threaded sockets (lamp holders). For bulbs powered by the mains supply, the thread is connected to neutral and the contact on the bottom tip of the base is connected to hot.

Hva folk vet!

Så E soklene er altså over 100 år gamle. Artig å vite, siden de jo fortsatt er i bruk.

Patentet for Edison-skruen må være eldre enn 1893.

In response to Edison's patent, Reginald Fessenden invented the bi-pin connector for the 1893 World's Fair. Other lamp bases include the bayonet mount and wedge base.
