Gas lighting in the historical center of Wrocław, Poland, is manually turned off and on daily.. Gas lighting is the production of artificial light from combustion of a fuel gas such as methane, propane, butane, acetylene, ethylene, hydrogen, carbon monoxide, coal gas (town gas) or natural gas.
A 175-watt mercury-vapor light approximately 15 seconds after starting. A closeup of a 175-W mercury-vapor lamp. The small diagonal cylinder at the bottom of the arc tube is a resistor which supplies current to the starter electrode. A mercury-vapor lamp is a gas-discharge lamp that uses an electric arc through vaporized mercury to produce ...
A flicker light bulb, flicker flame light bulb or flicker glow lamp is a gas-discharge lamp which produces light by ionizing a gas, usually neon mixed with helium and a small amount of nitrogen gas, by an electric current passing through two flame shaped electrode screens coated with partially decomposed barium azide. The ionized gas moves ...
On 23 September 1885, Carl Auer von Welsbach received a patent on the gas flame heated incandescent mantle light. [8] In 1914, the Coleman Lantern, a similar pressure lamp was introduced by the US Coleman Company. [9] [10] [11] In 1915, during World War I, the Tilley company moved to Brent Street in Hendon, and began developing a kerosene ...
Low-pressure sodium lamps are highly efficient electrical light sources, but their yellow light restricts applications to outdoor lighting, such as street lamps, where they are widely used. [1] High-pressure sodium lamps emit a broader spectrum of light than the low-pressure lamps, but they still have poorer color rendering than other types of ...
An acetylene gas miner's lamp. A carbide lamp or acetylene gas lamp is a simple lamp that produces and burns acetylene (C 2 H 2), which is created by the reaction of calcium carbide (CaC 2) with water (H 2 O). [1] Acetylene gas lamps were used to illuminate buildings, as lighthouse beacons, and as headlights on motor-cars and bicycles. Portable ...
A kerosene lamp (also known as a paraffin lamp in some countries) is a type of lighting device that uses kerosene as a fuel. Kerosene lamps have a wick or mantle as light source, protected by a glass chimney or globe; lamps may be used on a table, or hand-held lanterns may be used for portable lighting.
A pilot light is a small gas flame, usually natural gas or liquefied petroleum gas, which serves as an ignition source for a more powerful gas burner. Originally a pilot light was kept permanently alight, but this wastes gas. Now it is more common to light a burner electrically, but gas pilot lights are still used when a high energy ignition ...
