He was a poineer in physics and electricity. An arc lamp produces a very bright light from the electric arc betwen electrodes. Although it gave light, they were fiddly to use, as the electrodes burnt away. This was before the invention of incandescent lamps (Swann / Edison). So it was an early attempt and experiment to make light from electricity.
He also invented a safety lamp for use in coal mines. These protected a naked flame from inflammable gas, with a wire gause, to prent the lamp causing an explosion in mines. Do not confuse the two. The use of an arc lamp in a mine WOULD cause a fire or explosion.

What is a filmmaking arc lamp?
In early films, as below: "Arc lamps were used in some early motion-picture studios to illuminate interior shots."
What is used in high intensity discharge lamp to create light?
High Intensity Discharge (HID) lamps are a type of arc lamp. An HID lamp is comprised of a "glass" arc tube filled with a gas and a metal salt. The tube is generally fitted with two tungsten electrodes. Current applied to the electrodes is initially conducted in an arc through the gas. This initial arc raises the temperature of the metal salt until it vaporizes. At this point, the arc is conducted by the vaporized salt, greatly increasing the light output and decreasing the electrical current consumed.There are several types of HID lamps in current use:Mercury-vaporMetal-halide (MH)Ceramic MHLow Pressure Sodium-vaporHigh Pressure Sodium-vaporXenon short-arcEach chemistry offers a different mix of operating characteristics including light intensity, color temperature, color rendering index (CRI), energy efficiency, and lifespan. The "glass" from which the arc tube is made must withstand extremely high operating temperatures and is typically composed of translucent or transparent fused quartz or fused alumina..

What is a carbon arc lamp?
An arc lamp is a lamp that produces light by an electric arc. The carbon arc light, which consists of an arc between carbon electrodes in air, invented by Humphry Davy in the early 1800s, was the first practical electric light.
What did Charles f Brush invent?
He invented the arc lamp.
Who invented the heat lamp?
Sir Humphrey Davy invented the electric carbon arc lamp in 1801. Goerges Claude invented the neon lamp in 1911.
What year was the household lamp made?
The first household lamp using electricity was made in 1801. Sir Humphrey Davy invented the carbon arc lamp. It lasted for 40 hours.
Who invented bulb.?
Wikipedia, the free encyclopedia states, "In 1802 Humphry Davy had what was then the most powerful battery in the world at the Royal Institution of Great Britain. In that year he created the first incandescent light by passing the current through a thin strip of platinum, chosen because the metal had an extremely high melting point. It was not bright enough nor did it last long enough to be practical, but it was the precedent behind the efforts of scores of experimenters over the next 75 years until Thomas Edison's creation of the first practical incandescent lamp in 1879.[3] In 1809 Davy created the first arc lamp by making a small but blinding electrical connection between two charcoal rods connected to a 2000 cell battery. Demonstrated to the Royal Institution in 1810, the invention came to be known as the Arc lamp."Source: http://en.wikipedia.org/wiki/Light_bulb
What is an arc lamp?
An arc lamp is a general term for a class of lamps that uses an electric arc or voltage arc to create light. You've seen the bright light given off by electric arc welding, and the idea of the electric arc is the principle behind an arc lamp.
Which lamp is used for projecting pictures in the cinema hall?
carbon arc lamp
How did the Arc Lamp change the world of lighting?
The Arc Lamp is the first commercially successful form of electric lamp. It changed the world of lighting by setting the trend on carbon electric lights.
What is the type of gas in an arc lamp?
A combination of neon, argon, xenon, krypton, sodium, metal halide, and mercury. The common fluorescent lamp is a low pressure mercury arc lamp.
