What is Neon Burning?

Neon light is bright and luminous. It is filled with thin neon gas or other rare gas. It is a kind of cold cathode gas discharge lamp. A neon tube is a sealed glass tube with electrodes at both ends, filled with some low-pressure gas. A voltage of several thousand volts is applied to the electrodes, and the gas in the ionization tube causes it to emit light. The color of the light depends on the gas in the tube. Neon is a transliteration of neon light. Neon is a rare gas that emits a popular orange-red light, but the use of other gases produces other colors, such as hydrogen (red), helium (pink), and carbon dioxide ( White), mercury vapor (blue), etc.

Neon lights are the beauticians of the city. When the night comes, when the lanterns come on, the colorful neon lights make the city more beautiful. So how was neon light invented?

When the external power circuit is switched on, a high voltage of several thousand volts or even tens of thousands of volts will be generated at the output of the transformer. When this high

Most neon lights use cold cathode glow discharge. Because the cold cathode works, the whole lamp basically does not generate heat, and the efficiency of converting from electrical energy to light energy is high. Its life is much longer than ordinary fluorescent lamps. For example, it can guarantee the quality from material use, processing to installation. The service life of neon tubes can be as high as 2ooooh --3ooooh. In China's local standards, it is required to be no less than zaooha cold cathode discharge lamps A great advantage is that the number of switching times does not affect its life, so it is particularly suitable for advertising lamps that need to be switched frequently.
It relies on positive ions to bombard the cathode to cause the cathode to emit secondary electrons to maintain the discharge. Therefore, a certain cathode level is required to provide energy for the acceleration of positive ions. The magnitude of the cathode level is about 100V --- 200V.
In order to ensure that it can be discharged in the normal glow discharge area and no large cathode sputtering occurs during operation, the cathode must have a sufficient area, otherwise the large current will flow, which will cause the cathode current density to exceed the Ambassador cathode level. The rise and fall become abnormal glow discharge, which increases the cathode sputtering and shortens the life of the tube.
When possible, the neon tube should be as long as possible, and the inner diameter should be smaller. Try to increase the ratio of the pressure drop in the positive column area to the total pressure drop of the tube to improve the light efficiency.
In order to ignite the neon tube smoothly and work stably at a lower voltage, a high-voltage transformer (mostly magnetic leakage, but it will be gradually replaced by electronic because of its bulky and large power consumption) and reasonable matching to save engineering costs .
Neon lights use alternating current to work, so the two electrodes alternately serve as cathodes and anodes, and the area distribution of their glow discharges also alternates in the sequence direction. Due to the persistence of human vision, you can see that the glow uniformly covers the entire tube. The luminous effect is much better than using direct current. Therefore, the two electrodes should be as consistent as possible from the material to the processing.

Since the neon lamp is a vacuum electric light source, the entire production process needs to pay attention to vacuum hygiene. The materials and production are strictly in accordance with the technical requirements of electric vacuum, so as to ensure the quality.

In the manufacturing process of neon lights, whether it is a bright tube, a pink tube or a color tube, the manufacturing process is basically the same, they all need to go through glass tube forming, sealing electrodes, bombarding degassing, filling inert gas, sealing exhaust holes, etc. Craft.

Glass tube formingthat is, the process of burning, baking, and bending a straight glass tube into a pattern or text along the outline of a pattern or text through a dedicated fire head. The level of the production staff can be seen by the naked eye, and the level is low. Lamps made by people are prone to unevenness in the corners, too thick or too thin, wrinkles on the inside, and unevenness.

Sealing the electrodethe process of connecting the bent lamp tube to the electrode and the exhaust hole through the fire head, the interface must not be too thin or too thick, and the interface must be completely melted, otherwise slow air leakage is likely to occur.

Bombardmentthe key to making neon lights. It is the process of bombarding the electrode by high-voltage electricity, heating the electrode to burn water vapor, dust, oil and other substances that are not visible to the naked eye in the electrode of the lamp, removing these harmful substances, and vacuuming the glass tube. The temperature of the degassing by bombardment cannot be reached, and the above-mentioned harmful substances will not be completely removed, which directly affects the quality of the lamp. Excessive temperature of bombarded degassing will cause excessive oxidation of the electrode, causing oxygen to be produced on its surface

Neon is made up of "

The neon market is a mixed bag. Units with business licenses to undertake projects account for only 30% of the market. Such units have their own design, production, and installation capabilities, good reputation, product quality clearance, and later maintenance in place. They are the first choice for users.

In the second category, there is no business license to be linked to other units. Such "units" are not very professional, there is no guarantee of product quality, and subsequent maintenance is not in place.

The third category, the bag company, without any certificate, credibility and ability, shot one place for another, product quality and subsequent maintenance could not be mentioned at all.

Neon lights are a relatively professional industry. The products of regular units have good quality and long life. But it is the second and third types of companies that disrupt the neon market and give users the feeling that neon lights are easily broken. In fact, the life of neon lights is longer than that of fluorescent lights. For your benefit, please choose a licensed, capable and reputable unit.

In the past, almost all neon lamp manufacturing companies used ordinary glass tubes and ordinary electrodes. As people's requirements for products increased, high-lead glass tubes, ceramic ring electrodes, and three-color powder tubes, gradient rainbow neon lights are becoming more and more popular in people's lives. To make people s lives more exciting and bright

In the fashion concept of modern urban people, scenery and light are the combination of rhythm. The light is properly arranged and the natural environment space structure, the use of hidden-exposed, suppressed-yang, fully reflects the oriental civilization atmosphere of traditional culture, reproduces the dialectical relationship of humanistic atmosphere, increases the change of space, and forms a step change Night scene effect. Scientific scenery and light need analysis and understanding, landscape lighting needs appreciation and taste, and art needs deep thought and perception. The art of landscape lighting must pass through light and lighting to produce the vitality of life. Lighting can change the appearance of the environment. Artistic lighting and colors make up dynamic and static light, sound, and color landscapes. It also shows the simplification, sculpting, and fashioning of landscape garden lamps, and embellishes the natural environment.

Neon light is a traditional light source, a cold cathode low-pressure gas glow discharge tube with built-in filament electrodes. Cold electron emission is generated by high-pressure bombardment, and arc discharge is excited, so that gas atoms in the tube are radiated. Over time, great progress has been made in neon technology. The new vacuum technology has enhanced the accuracy and consistency of the processing of electronic tubes, and the service life has reached 10 000 h. The breakdown and operating voltage of neon lighting circuit components are very high. Neon technicians have rich experience and know how to install and use it safely. Use a transformer with a lower open circuit voltage level to shorten the length of the wire as much as possible. Use high-quality insulation materials. With the advancement of neon technology, the protection device is designed and implemented using microelectronics technology. The microprocessor controls the brightness changes of the three primary color tubes separately. It can not only control the neon light on and off, but also perform digital dimming and color mixing. The colorful colors greatly enhance the rendering effect of neon lights, and improve the flexibility and high reliability of neon lights. Neon lights are now standardized in design, manufacture, and installation, and they also achieve the same attractive landscape effects as LEDs. The neon light also has visual impact and artistic appeal, in a unique way and shape to reflect the art of human pursuit of beauty in life, the moonlight, starlight and light to reproduce the natural or human landscape during the day and the landscape effect at night ^[2] .
