The Davy lamp was used to tell the miners if they hit a spot of dangerous gas's flame would go out every time they hit a spot of dangerous gas and because of that little lamp allot of miners lives were saved.

∙ 7y agoThe Davy lamp is a gas lamp which can be safely used in flammable atmosphere. It was used in mines where fire damp was a danger. The lamp comprised a wick burning heavy vegetable oil has surrounded by a fine mesh. The allowed air (and firedamp) to go into the lamp and light to come out. But the mesh was too fine for the flame to ignite the flammable gases outside. If firedamp was present the flame burned bluer and so was a visible warning to miners.
It was also useful for alerting them to non-flammable but toxic gases such as CO2. The height of the flame would reduce in its presence alerting the miners to a hazard.

Sir Humphry Davy in 1815
The danger of methane gas (firedamp) being ignited by an open flame in coal mines was much reduced by the development of the flame safety lamp stemming from the work of Dr. William Clanny, George Stephenson and Sir Humphrey Davy. It is Davy who is credited with the true invention of the flame safety lamp in 1816. His idea was to isolate the flame from the flammable gas by means of a wire gauze surrounding the flame. Davy demonstrated that burning gases, on passing through the wire mesh is broken up into tiny streamlets which are so cooled by contact with the metal of the mesh that the flame is extinguished. It was found that the greatest safety could be obtained by a standard mesh formed by 28 steel wires per inch making 784 openings per square inch.
The miners flame safety lamp was first invented in 1815 by Sir Humphry Davy after the danger of methane gas and open flames prompted he and others to create a safer solution.
Depends. Lamps can certainly be built to work on either AC, or DC, or both. But some lamps, particularly those with electronics in them, either a dimmable lamp, or a fluorescent lamp, may only work with one type of electricity.
You require a powerful electric magnet to release pins, and the correct holder. These lamps are impossible to open without one unless you cut it apart, so just look at it and enjoy.

Sir Humphry Davy
The Davy lamp was invented by Sir Humphry Davy in 1815. It was designed to prevent explosions in coal mines by safely illuminating the area without igniting flammable gases.
sir humpherry
The Davy lamp was invented by Sir Humphry Davy in England in 1815. This safety lamp was designed to prevent underground mine explosions caused by the ignition of flammable gases.

He devised the lamp
The Geordie lamp had a glass shield around the flame to protect it from drafts, while the Davy lamp used wire gauze to prevent the flame from igniting surrounding methane gas. The Geordie lamp produced a brighter light due to the glass shield, but the Davy lamp was safer in detecting the presence of methane gas.
The Davy Lamp was invented by Sir Humphry Davy in 1815. It was designed to prevent explosions in coal mines by safely burning methane gas that was present in the mines.
The Davy lamp helped canaries because it was a safety lamp used in coal mines to detect the presence of dangerous gases like carbon monoxide. Canaries are sensitive to these gases, so if the bird showed signs of distress or illness, miners would know to evacuate the mine to avoid danger.
The Davy lamp was invented in 1815 by Sir Humphry Davy. It was designed to improve safety in mines by preventing explosions caused by flammable gases like methane.
