Shanghai Shaliang Technology Co., Ltd. is a company specializing in neon light processing and neon light production. Neon lights are the beautician of the city. Whenever night falls and the lights first come on, the colorful neon lights make the city extraordinarily beautiful. So, how was neon light invented? Neon lights outdoor lighting decoration, picture (this is a lamp) It is said that neon lights were accidentally discovered by British chemist Ramsay during an experiment. It was a night in 1999. Ramsey and his assistant were conducting experiments in the laboratory to check whether a rare gas conducts electricity.
Ramsey injected a rare gas into a vacuum glass tube, then connected the two metal electrodes enclosed in the vacuum glass tube to a high-voltage power supply, and concentrated on observing whether the gas could conduct electricity.
Suddenly, an unexpected phenomenon occurred: the rare gas injected into the vacuum tube not only began to conduct electricity, but also emitted an extremely beautiful red light. This magical red light surprised Ramsay and his assistants, and they opened the door to the neon world. Neon outdoor lighting decoration, Turamsai named this rare gas that can conduct electricity and emit red light neon. Later, he continued to conduct experiments on the properties of other gases to conduct electricity and emit colored light, and successively discovered that xenon can emit white light, argon can emit blue light, helium can emit yellow light, and krypton can emit deep blue light. Different gases It can emit different colors of light, colorful, like a beautiful rainbow in the sky. This is where neon lights get their name.
The way to make neon lights is to use low melting point soda-lime silicate glass as lamp tubes, design different patterns and text according to needs, process them with a blowtorch, then sinter the electrodes, and then evacuate them with a vacuum pump, and assemble them according to requirements. The colors are made by filling different rare gases. Modern neon lights are more sophisticated. Some bend glass tubes into various folded shapes to create more attractive graphics. Others apply phosphor to the inner wall of the tube to make the colors brighter and more colorful. Some neon lights are equipped with automatic ignition. The device makes the lights of various colors shine and fade one after another, making the city night more colorful. Neon lights outdoor lighting decoration Tianjin Haihe Scenery Neon lights have been around for hundreds of years since their inception. It is a special low-pressure cold cathode glow discharge electric light source that is different from other arc lamps such as fluorescent lamps, high-pressure sodium lamps, metal halide lamps, mercury lamps, and incandescent lamps. Neon lamps emit light by filling a low-pressure inert gas in a glass tube with a cold cathode glow discharge under a high-voltage electric field. The light color of neon lights is determined by the spectral characteristics of the inert gas filled. Light tube neon lights are filled with neon gas, neon lights emit red light. Fluorescent neon lights are filled with argon and mercury, and neon lights emit blue, yellow and other lights. These two categories Neon lights all rely on stimulated radiation of working gas atoms in the lamp tube to emit light.
High efficiency
Neon lamps rely on the electrode tips at both ends of the light to ignite the rare gases in the lamp tube under a high-voltage electric field. It is different from ordinary light sources that must burn the tungsten wire to high temperatures to emit light, causing a large number of Electric energy is consumed in the form of heat energy, so with the same amount of electric energy, neon lights have higher brightness.
Low Temperature
Due to its cold cathode characteristics, the temperature of the lamp tube is below 100°C when working, so it can be placed in the open air, exposed to the sun and rain, or worked in water. Also due to its working characteristics, the neon light spectrum has strong penetrating power and can still maintain good visual effects in rainy or foggy days.
Low energy consumption
In an era of continuous technological innovation, the manufacturing technology of neon lights and the technical level of related components are also constantly improving. The application of new electrodes and new electronic transformers has greatly reduced the power consumption of neon lights, from watts per meter of lamp tube to watts per meter of lamp tube.
Long lifespan
Neon lamps have a lifespan of more than 10,000 hours under continuous operation without power. This advantage is difficult to achieve by any other electric light source.
Flexible and diverse
This is an example of today's advertising supplies
Neon lights are made of glass tubes. After firing, the glass tubes can be bent into any shape. They have great flexibility. By choosing different By filling different types of tubes with different inert gases, neon lights can produce colorful, multi-colored light.
Highly dynamic
The neon light screen is composed of a constantly bright lamp tube and a dynamically emitting scanning tube. It can be set to seven color scanning: jumping scanning, gradient scanning, and mixed color scanning. The scanning tube is controlled by a scanning machine equipped with microcomputer chip programming. The scanning tube turns on or off according to the programmed program, forming a flowing picture, which is like a rainbow in the sky, like the Milky Way on earth, or even more like a dream world, which is fascinating and enchanting. Unforgettable. Therefore, neon lights are a form of advertising that requires less investment, is highly effective, and is economical and practical.

. Structure
Neon light material effect Neon light is a low pressure cold cathode glow discharge lamp. Its structure and components ensure normal glow discharge, and the working substances make it possible to obtain the required light color.
Neon lights are composed of lamp tubes and high-voltage transformers. The lamp tube consists of a glass tube and an electrode chamber. The electrode chamber is composed of electrodes, mica sheets (or porcelain rings) and electrode leads. The glass tube is filled with working gas, and some of the inner walls of the glass tube are coated with phosphor powder. There are two types of high-voltage transformers: magnetic leakage transformers and electronic transformers. They are essential components for igniting neon light tubes.
Glass tube
The main functions of the glass tube are to fill the working gas, connect the two electrodes and transmit visible light. Common neon glass tubes include open tubes, pink tubes and colored tubes.
Electrode
The electrode is used to emit electrons and collect electrons and positive ions. It is made of metal that is resistant to positive ion bombardment, has a high melting point, and is easy to emit electrons.
.Mica sheet (or collar)
The main function is to support the electrode, insulate heat and reduce cathode sputtering on the inner wall of the glass tube. The support electrode prevents it from shifting, loosening and contacting the glass tube. The heat insulation can prevent the glass tube from bursting and reduce the cathode sputtering on the inner wall of the glass tube, which can extend the life of the lamp.
Electrode lead
It can connect the electrode to the external circuit. It needs to be made of materials with good conductivity and a thermal expansion coefficient similar to that of glass. The electrode lead is mostly made of Dume silk.
Working gas
Operating gases are mostly inert gases. Neon and nitrogen are the most commonly used working gases. Neon is often filled into open tubes to make red neon lights. Hydrogen is mostly composed of hydrogen and mercury mixed gases and is filled into powder. Tubes make neon lights in other colors.
Light powder
The inner wall of the fluorescent powder tube is coated with different types of phosphors, which can be easily mixed with hydrogen and mercury gas mixtures to make neon lights of various colors.
High-voltage transformer
It is a current stabilizing device connected to the neon lamp circuit. It and the lamp tube form a complete set of neon lamps. The electrical properties of glow discharge have the following characteristics: first, it requires a higher ignition voltage and lower operating voltage; second, it has negative volt-ampere characteristics, which makes the discharge unstable. Using a magnetic leakage high-voltage transformer or an electronic step-up transformer can provide the lamp with a voltage of up to } to make the lamp ignite and glow. As soon as the gas starts to discharge, the voltage will immediately drop to a constant value to maintain the normal glow of the lamp during discharge. a stable state.
Lamp
． The specifications are divided into millimeters and other thicknesses.
． Classified by glass material
① Soda glass tube (or lime glass tube) has poor stability. It is easily deteriorated and efflorescent (weathered) when exposed to moisture. It has poor fastness and is prone to bursting. Approximately % of this material is used in China.
② Lead glass tube (also known as red lead glass tube) has better thermal properties, mechanical properties, electrical properties, chemical stability properties, vacuum properties and optical properties than sodium glass, and its weather resistance and service life greatly exceed that of sodium glass. Glass, most commonly used in the world, is lead glass tubes, and the usage in China has reached about %. For all manufacturers that pursue good quality, users choose lead tubes to make neon lights. Lead glass is divided into heavy lead glass, medium lead glass and light lead glass according to the lead content.
③ Colored glass tube, this kind of glass tube has been filled with dye when drawing the glass tube, and the produced glass tube has a colored glass tube.
． Divided by phosphor powder materials used in neon tubes: ① Most neon tubes used are sprayed with ordinary phosphor, which is relatively cheap and can generally meet the requirements of various colors. ② Compared with ordinary phosphors, three-primary color phosphors (also called rare earth phosphors) have better brightness, color and freshness.
． The process of spraying phosphor powder is divided into two types: water coating and glue coating.
① Use water to spray phosphor powder mixed with alcohol or ketone on the inner wall of the lamp tube and let it dry naturally. ②Glue coating is sprayed with glue mixed with fluorescent powder, and then dried in an oven. Its viscosity and fastness are much better than water-coated powder tubes. Most advanced countries use three-color glue-coated leaded glass tubes to make neon lights, and some manufacturers in China already use this kind of neon tubes.

Transformers
． Neon light flux leakage transformer (also known as inductance transformer, iron core transformer) is characterized by good reliability, high brightness of the load lamp, consistent light color, and long life. The disadvantage is that it is relatively bulky. Most outdoor neon lights abroad and in Shanghai use this type of transformer. kind of transformer. The specifications of the inductor transformer are: The well-known brands of neon light inductance transformers include Yiya and Tonghui.
． Electronic transformers (also known as high-frequency cold start tubular discharge lamp (neon lamp) electronic converters or neon lamp power supplies) have the advantages of light weight, convenient manufacturing, and saving of metal materials. At present, the quality of domestically produced electronic transformers is stable and has a certain scale, including Some companies also export in bulk. However, the brightness of the electronic transformers produced by many units is not as bright as it should be, and it is a bit dwarfed when used outdoors. Electronic transformers are divided into two types: DC and AC. Due to the one-way conduction of DC electronic transformers, one end of the lamp is often bright and the other is dark. In addition, the output frequency of the electronic transformer will be affected by the length of the load lamp. In the same neon lamp, uneven light color will occur due to the different lengths of each lamp. In order to reduce costs, some manufacturers are unwilling to use high-quality electrical components, and the processing technology is crude, resulting in poor reliability and short lifespan. The specifications of electronic transformers include,,,,, and other specifications. They are also called rice machines, rice machines, rice machines, rice machines, rice machines, etc. It is possible to truly produce electronic transformers that meet the requirements for neon lights, but their price will be close to the price of inductive transformers. In order to compete at low prices and gain market share, some manufacturers sacrifice the brightness, reliability, and lifespan of neon lights to gain market profit.
