Davy lamp Davy lamp The Davy lamp is a safety lamp for use in flammable atmospheres, invented in 1815 by Sir Humphry Davy. 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." Davy's invention was preceded by that of William Reid Clanny, an Irish doctor at Bishopwearmouth, who had read a paper to the Royal Society in May 1813. The more cumbersome Clanny safety lamp was successfully tested at
Safety lamp copper coated with a fusible metal. If the lamp gets too hot the metal melts and closes up the air holes, extinguishing the lamp. The lamp has been tested and according to Lupton ""successfully resisted every effort to explode it up to a velocity of more than 100 feet per second"". It was not until tungsten filaments replaced carbon that a portable electric light became a reality. An early pioneer was Joseph Swan who exhibited his first lamp in Newcastle upon Tyne in 1881 and improved ones in subsequent years. The Royal Commission on Accidents in Mines set up in
