Sir Humphry Davy, 1st Baronet, FRS, MRIA, FGS (17 December 1778 – 29 May 1829) was a British chemist and inventor who invented the Davy lamp and a very early form of arc lamp.
The Davy lamp is a safety lamp used in flammable atmospheres, invented in 1815 by Sir Humphry Davy. [1] It consists of a wick lamp with the flame enclosed inside a mesh screen. It was created for use in coal mines , to reduce the danger of explosions due to the presence of methane and other flammable gases, called firedamp or minedamp .

The carbon arc light, which consists of an arc between carbon electrodes in air, invented by Humphry Davy in the first decade of the 1800s, was the first practical electric light. [1] [2] It was widely used starting in the 1870s for street and large building lighting until it was superseded by the incandescent light in the early 20th century. [1]
Invented by Humphry Davy around 1805, the carbon arc was the first practical electric light. [ 33 ] [ 34 ] It was used commercially beginning in the 1870s for large building and street lighting until it was superseded in the early 20th century by the incandescent light. [ 33 ]
Within months of Clanny's demonstration of his first lamp, two improved designs had been announced: one by George Stephenson, which later became the Geordie lamp, and the Davy lamp, invented by Sir Humphry Davy. Subsequently, Clanny incorporated aspects of both lamps and produced the ancestor of all modern oil safety lamps.
1815 Humphry Davy Exhibited The Davy Lamp 1815 George Stephenson Exhibited his Lamp The Davey Safety Lamp was made in London by Humphry Davy. George Stephenson invented a similar lamp but Davys invention was safer due to it having a fine wire gauze that surrounded the flame. This enabled the light to pass through and reduced the risk of ...
