The voltage of high pressure mercury lamps is relatively high, so it is called high pressure mercury

Consists of light-emitting tubes, electrodes, argon.

Mercury, inner and outer tubes, etc., there are two main electrodes and auxiliary electrodes in the light-emitting tube, and argon and mercury are encapsulated, and nitrogen is sealed in the outer tube to protect the light-emitting tube and block ultraviolet rays.

Fluorescent lamp. The working principle is different from that of a high-pressure mercury lamp. The fluorescent lamp relies on electrodes at both ends to make the electrons in the fluorescent lamp move back and forth and hit the phosphor on the wall of the fluorescent lamp.

And glowing. For details, please see High-pressure mercury lamps use ultra-high-pressure mercury vapor (1MPa or more) to obtain visible light.

of light sources. Mercury vapor discharges emit strong radiation in the ultraviolet to visible range.

High-pressure mercury lamps are also known as"High-pressure mercury lamps", UV lamps. A type of gas discharge lamp that uses high-pressure mercury vapor discharge to emit light. The lamp is fitted with a pair of electrodes and air is extracted and filled with a small amount of argon and liquid mercury.

After the power is applied, the argon gas discharge heats and vaporizes the mercury, and the mercury vapor is excited by electrons and discharges to produce a strong glow. High luminous efficiency and long service life, but ultraviolet light. More.

High-pressure mercury lamps are electric light sources that use the high pressure (mercury vapor) produced when mercury is discharged to obtain visible light.

It can be seen that the high voltage you are talking about is not the same thing, but the high voltage generated by mercury discharge (mercury vapor is used to obtain an electric light source for visible light. Either a high-voltage mercury lamp or a high voltage.

Mercury lamp, when turned on, requires high pressure to break down mercury vapor, and the voltage returns to normal when lit.

The high-pressure mercury lamp is what everyone calls it.

Mercury lamps are divided into low-pressure, high-pressure and ultra-high-pressure mercury lamps according to the mercury vapor pressure when they work. , independent of voltage.

The voltage of high-pressure mercury lamps is relatively high, so they are called "high-pressure mercury lamps".

A high-pressure mercury lamp is an electric lamp that emits light by discharging high-pressure mercury steam. When the high-pressure mercury lamp is connected to the power supply, the internal mercury vapor pressure can reach 2-15 atmospheres, which is much higher than the gas pressure of ordinary fluorescent tubes, so this crude lamp is called high-pressure mercury lamp.

Supplementary information: High-pressure mercury lamp, also known as high-pressure mercury lamp, has the advantages of high light efficiency, long life, low cost, and power saving, and can generally be used in industrial lighting, street lighting, courtyard lighting, flood lighting and other fields.

High-pressure mercury lamps are mainly composed of fluorescent blisters and a discharge tube, and the inside of the discharge tube has high-pressure mercury vapor. High-pressure mercury lamps are UV-cured standard lamps that generate a lot of heat and usually need to be cooled with air or water.

After the electricity is applied, the argon gas discharge heats and vaporizes the mercury, and the mercury vapor is excited by the electrons and discharges to produce a strong glow, so it is called a high-pressure mercury lamp. The high-pressure mercury lamp is composed of a light-emitting tube, an electrode, argon, mercury, an inner and outer tube, etc., in which there are two main electrodes and an auxiliary electrode, and argon and mercury are encapsulated, and nitrogen is encapsulated in the outer tube to protect the light-emitting tube and block ultraviolet rays.

The high-pressure mercury lamp is dangerous due to the ultraviolet rays it releases during use, and the lamp must not be touched by hand in the use of the high-pressure mercury lamp, so as not to cause damage or reduce the life of the lamp. In some high-pressure mercury lamps with wiring directions, it is necessary to pay attention to whether the direction is correct, such as the wrong direction will lead to the destruction of the high-pressure mercury lamp, affect its service life, and also appear high-pressure mercury lamp surface overheating. Due to the high pressure in the high-pressure mercury lamp, attention must be paid to avoid external forces such as bumps and scratches.

The voltage of the high-pressure mercury lamp is relatively high, so it is purely called the high-carrying pressure concealment liquid mercury lamp. （）

a.That's right. b.Mistake.

Correct answer: B

Because high-pressure mercury lamps are electric lamps that use high-pressure mercury vapor discharge to emit light.

When the high-pressure mercury lamp is connected to the power supply, the internal mercury vapor pressure can reach 2-15 atmospheres, which is much higher than the gas pressure of ordinary fluorescent tubes, so this kind of electric lamp is called high-pressure mercury lamp.

The high-pressure mercury lamp is a high-pressure mercury vapor discharge lamp coated with phosphor on the inner surface of the glass shell, and the soft white light is simple. Low cost, low maintenance cost, can directly replace ordinary incandescent lamp, with high light efficiency, long life, power-saving and economical characteristics, suitable for industrial lighting, warehouse lighting, street lighting, flood lighting, safety lighting, etc.

The high-pressure mercury lamp is named after how it works. A high-pressure mercury lamp is made by putting high-pressure mercury vapor in a tube, and then ionizing the gas so that the electrons in the ionized gas collide with the mercury atoms, so that the mercury atoms emit ultraviolet light. These ultraviolet rays are absorbed by phosphors and converted into visible light.

Therefore, a high-pressure mercury lamp is considered a type of fluorescent lamp.

High-pressure mercury lamps have many advantages, including their high efficiency. High-pressure mercury lamps have high illuminance and high light efficiency to meet many different lighting needs. In addition, high-pressure mercury lamps have a long life, low maintenance costs, and a service life of thousands of hours.

These advantages make high-pressure mercury lamps the lighting fixtures of choice for many applications.

While high-pressure mercury lamps have many advantages, there are also some problems. Due to the strong UV radiation produced by high-pressure mercury lamps, proper precautions need to be taken to protect the user and the environment. In addition, the color temperature of high-pressure mercury lamps is skewed to blue, which may not be suitable for some applications.

Finally, it takes a while for a high-pressure mercury lamp to heat up when it is activated, which can lead to some lighting needs going unmet.

High-pressure mercury lamp is a kind of lighting device that uses gas discharge to produce ultraviolet rays, and fluorescent first sock powder glows under ultraviolet irradiation. This kind of lamp has strong ultraviolet radiation, and the light produced is monochromatic, with high color temperature and strong brightness, which is a widely used lighting fixture.

Overall, high-pressure mercury lamps are a widely used lighting device, and lead excitation has many advantages and some disadvantages. As technology continues to advance, the shortcomings of high-pressure mercury lamps will be improved, allowing them to continue to play a wider role in the future.
