What is an arc lamp What is the meaning of an arc lamp What is the meaning of an arc lamp

Arc lamp A type of strong light that is often used as illumination for outdoor color photography because the color temperature is quite close to the color temperature of daylight.

Generally, the light bulb is a filament heating and luminescence, and the arc lamp is the use of the arc generated between the electrodes to emit light, with high color temperature and strong brightness.

It is that the life is short, easy **, and the light is too bright.

To put it simply, it is to use the light generated by the arc to do lighting, like our common electric welding machine, which uses the arc to melt the metal and emit a strong light when working. The lamp is made by using the principle of arc light, and there are two common types: gas and metal lamp.

The word arc light is explained as: arc light húguāngdēng. (1) A kind of electric lamp, when an electric current passes between two incandescent carbon rods or metal electrodes, it causes an arc to emit light, and the gas around the electrodes is at atmospheric pressure.

What is the specific explanation of arc lamp, we will introduce it to you through the following aspects:

1. Citations and explanations [click here to view the details of the plan].

A lighting appliance that uses an electric arc generated by a carbon electrode as a light source. This lamp emits extremely strong light and can be used as a searchlight, and can also be used for film production and projection.

2. Chinese dictionary.

A lamp that uses an electric arc generated by a carbon electrode as a light source. The luminous efficiency is high, and the light color is close to daylight, which can ensure the correct color reproduction for color films. It is mostly used in electric lamps that require high brightness, such as searchlights, large movie projectors, and floodlights.

Arc. Radian. Electric arc.

Arc. radical : bow; Explanation of Light Light ā The sun, fire, electricity, etc., radiates something that dazzles the eyes and makes people feel bright and can see objects

It presents an arc-shaped white light and produces a high-temperature gas discharge phenomenon. Whether in thin gases, metal vapors or atmosphere, when the power supply is large and can provide a large enough current (a few amperes to tens of amps), the gas breaks down, emits strong brilliance, and produces high temperatures (thousands to tens of thousands of degrees), the form of self-sustaining discharge of this gas is arc discharge. The method of arc discharge often produced by the bending stool is to separate the two electrodes after contact, and the temperature of the cathode surface increases sharply due to the short circuit, resulting in hot electron emission.

The thermal electron emission causes the collision ionization and the secondary electron emission of the cathode to increase dramatically, so that the gas between the two poles has good conductivity. The characteristic of the arc light burial is that the voltage is not high, and the voltage between the two poles where the current increases decreases, and there is a strong brilliance.

There is also a type of arc discharge called cold cathode arc discharge, and the cathode is made of a material with a low melting point, such as mercury. The vapor evaporated from the surface of the cathode is ionized and accumulates near the surface of the cathode to form a space positive charge layer, and the strong electric field formed in the extremely narrow area between this charge layer and the cathode causes field-induced emission, causing the current to increase dramatically and produce an electric arc.

Arc discharge is used in a wide range of applications. It can be used as a strong light source, in spectroscopic analysis as a light source for the spectrum of excitation elements, in industrial smelting, welding and cutting of metals with high melting points, in medicine as an ultraviolet source (mercury arc lamp), and so on. However, the arc fire generated when the high-current circuit switch is disconnected is extremely harmful, and arc extinguishing measures should be taken.

The arc lamp was discovered by accident in 1821, twenty-six years before Edison was born, by the Englishman Havrey-David. At that time, he stretched out two wires from two batteries and connected them to the charcoal rods, which suddenly emitted a dizzying light, thus inventing the "arc lamp".
