Neon Glow LampFlexible And Diverse
Aug 22, 2017

Neon is a gas-containing lamp, usually used for advertising signs and other purposes. Neon is usually a glass tube, containing low pressure neon or other inert gas, with a weak DC or AC power through the tube and produce orange-red light. In the AC excitation of the neon, both electrodes will produce light, and DC excitation of the neon, only the negative will produce light. This phenomenon allows the neon lights can be used to distinguish between DC and AC power, and distinguish the two poles of direct current. The actual composition of the gas in the tube is 99.5% neon and 0.5% argon, which is lower than pure neon.

1. High efficiency

Neon lights rely on light ends of the electrode head in the high voltage electric field under the lamp of the rare gas burning, it is different from the ordinary light source must be tungsten wire to high temperature to light, causing a lot of energy in the form of heat energy is consumed, With the same amount of electricity, neon lights have higher brightness.

2. Low temperature

Neon because of its cold cathode characteristics, the work of the lamp temperature below 60 ° C, so can be placed in the open sun and rain or work in the water. Also because of its working characteristics, neon spectrum has a strong penetration, in the rain or fog still maintain a good visual effect.

Low energy consumption

In the era of continuous innovation, neon manufacturing technology and related parts of the technical level is also continuous improvement. New electrode, the application of new electronic transformers, so that the power consumption of neon lights greatly reduced by 56 watts per meter lamp power consumption per kilometer to 12 watts per meter.

4. long life

Neon lights in the case of continuous work without electricity, life of 10,000 hours or more, this advantage is that any other electric light is difficult to achieve.

5. Flexible and diverse

Neon lights are made of glass tube, after firing, glass tube can be bent into any shape, with great flexibility, by selecting different types of tubes and filled with different inert gas, neon can get colorful, a variety of colors of light The

working principle

When the external power supply circuit is connected, the transformer output will produce thousands of volts or even tens of thousands of volts of high pressure. When this high voltage is applied to the electrodes at both ends of the neon tube, the charged particles in the neon tube are accelerated in the high voltage electric field and fly to the electrode, which can generate a large amount of electrons. These excited electrons are accelerated in high voltage electric fields and collide with gas atoms in the lamp. When these electrons hit the free gas atoms of the energy is large enough, it can make the gas atoms ionization and become positive ions and electrons, which is the gas ionization phenomenon. The collision between the charged particles and the gas atoms, the excess energy is emitted in the form of photons, which completes the neon light glowing the whole process.
