Neon lamp can work in the open air in the sun, rain or water because of its cold cathode characteristics, and the lamp temperature is below 60℃ when working. Because of its working characteristics, neon light spectrum has strong penetrating power and can still maintain good visual effects in rainy or foggy days. Neon lamp in the era of technological innovation, the manufacturing technology of neon lamp and the technical level of related parts are constantly improving. The application of new electrodes and new electronic transformers has greatly reduced the power consumption of neon lamps, from 56 watts per meter to 0/2 watts per meter/kloc.
Neon lamp, also known as neon lamp, is a new type of lighting fixture. Neon lamp has always been favored by customers, with strong professionalism, long service life and good quality. This is mainly the place where neon lights are superior to other lighting equipment. The circuit current of neon lamp is limited, and the maximum current can only be managed at 128. The choice of wick in neon lamp circuit needs to enlarge the current of neon lamp. The way to enlarge the current of neon lamp is to contact the current with the pin of neon lamp. Neon lamp, as an important branch of electric light source, is the most widely used decorative lantern. When a variety of neon forms are with TINT, it is often the time that attracts us the most. The color change and tone change of neon lights are controlled by computer programs, and people pay more and more attention to colorful life.
Red neon lamp is a kind of gas discharge lamp and a new type of lighting. Red neon light is the most common one now. Red neon lights and fluorescent glow lights can be used in various applications by using their luminous characteristics, electrical characteristics and dual-purpose characteristics. Examples of the application of luminous characteristics of red neon lights are: indicating power supply, fuse monitor, indicating high-frequency voltage and indicating with measuring pen on various household appliances and distribution boards. In the case of continuous work, the service life of red neon lights can still reach 2000 hours. The line structure of red neon lamp is expressive, and its bright, beautiful and dynamic characteristics are irreplaceable by any electric light source. Red neon lights are the most commonly used and relatively cheap, which is also the reason why red neon lights are popular. Neon lamps bombard electrodes with high-voltage electricity. Neon lamps are a professional industry.
Red neon lights can be divided into super brightness, high brightness and general brightness. Red neon lights are characterized by good reliability, bright colors, long service life and relatively small size, which are suitable for small household appliances. The luminous characteristics of neon lights are used to indicate the power supply of various household appliances and circuit boards, and neon lights are more eye-catching. It is used for indication in electrical equipment, electronic circuits or instruments, circuit elements and electrical equipment by using its discharge and light-emitting characteristics, electrical characteristics or both. When the red neon lamp works normally, it gives off orange light.
A, the scope of use of neon lights:
Two. Form, shape, size and electrode shape:
Third, color: red, green, blue, yellow and white
Four, materials and structure:
4- 1 broken shell-neon bulb, special glass material.
4-2 electrode-filament material, neon discharge electrode.
4-3 Lead-in wire-Dumex material to form neon sealing joint with glass.
4-4 Inert gas-working gas filled in neon tube.
4-5 Electron emission paste-the emission material coated on the surface of the electrode.
The surface of the lead-in wire is coated with 4-6 wires of silver, which is convenient for welding and effective contact.
Neon lamp features: high voltage and low current. The high-voltage power supply of the neon tube is provided by the transformer, which is a single-phase transformer. The low-voltage output voltage is 220V AC, the high-voltage output voltage is 15000 V, and the capacity is 450 VA ... That is to say, when the neon lamp works normally, the neon transformer limits the maximum current passing through the lamp circuit. According to the safety requirements, the secondary no-load voltage of neon transformer generally does not exceed 15000 volts, and the secondary short-circuit current is 15-25% higher than the normal working current. The commonly used neon transformer has a capacity of 130VA, a hand shear of 600V, a ballast start of 450VA, a primary voltage of 220V and a current of 2A. Secondary voltage 15000 volts, current 24 mA, secondary short-circuit current 30 mA. It can light a lamp with a diameter of 12 mm and an unfolded length of12 m. Generally, neon lights are powered by specially designed leakage transformers. After the workers connect the wiring and power supply, the high voltage generated by the transformer secondary ionizes the gas in the lamp tube and emits color glow. The starting voltage of the lamp is directly proportional to the length of the lamp tube, inversely proportional to the diameter of the lamp tube, and related to the type and pressure of the gas filled.
Among many names of electric light sources, neon lights are named after the luminous principle of light sources or the names of luminous substances, but the names of neon lights are puzzling. Neon lamp is a branch of electric light source products, belonging to cold cathode glow discharge light source. Neon lamp is a rare gas filled in the early neon lamp, so it can be transliterated as neon lamp or neon lamp. The transliteration of the word NEON means rainbow in Chinese. It happens that neon lights are filled with rare gases such as helium, neon, argon, krypton and neon, and their gorgeous colors are as gorgeous as rainbows in the sky. Therefore, China has been using the name Neon, and has not given it a classified name according to the naming method of electric light source products. It can be said that the advent of neon lights is based on the technological development of vacuum and gas discharge. Looking back on the development history of neon lights, it can be traced back to the Middle Ages. During this period, in some countries with earlier industrial revolution in Europe, the research on neon gas discharge phenomenon was very active, especially the rich colors of red neon gas discharge were applied one after another, which was the historical background of neon success. The prototype of neon lights. In the celebration of Queen Victoria's 60th birthday, Gaisela neon lights were used as decorative lighting for the festive atmosphere. This primitive model neon lamp uses graphite as the electrode, and nitrogen and carbon dioxide gas are filled in a transparent glass tube with a diameter of 45 mm. The former emits pink light, while the latter emits white light, which is also very bright when it is bent into a spiral or text pattern. The green neon lamp is easy to react with the electrode because of the active chemical properties of the filling gas, and the graphite electrode has a high sputtering rate, which quickly forms a film on the glass tube wall, absorbs the filling gas and reduces the gas pressure in the tube. Therefore, this neon lamp has a short life and no practical value. Using inert gas instead of active gas as the filling gas of neon lamp not only greatly prolongs the life of neon lamp, but also enriches the color of neon lamp, which is a major technological breakthrough in the development of neon lamp. The appearance of neon lights caused a great sensation and achieved success. Since then, Claude has been concentrating on expanding the research on the applicability and application of neon lights. During this period, due to the outbreak of World War I, Claude's research progress was slow and was once interrupted. It was not until 19 15 that Claude officially obtained the patent for the invention of neon lights. It is the first time in the United States that blue neon lights have been used as a light source to indicate the safe landing of airport runways. Lindenbergh vigorously promoted the advantages of neon lights and broadened their uses, making neon lights an effective commercial advertising medium, which was widely recognized and welcomed by the society and developed rapidly all over the world in the 1920s. Neon lamp is basically the same in principle, material, technology and equipment, and its biggest feature is the use of transparent and colorless glass tubes, so we regard it as a stage in the history of neon lamp development. This kind of yellow neon lamp made of transparent glass tube mainly uses glow as light source, that is to say, the color of neon lamp tube is determined by gas composition and pressure. Therefore, it is very important to master the color characteristics of various neon lamp gases during glow discharge.
Neon lamp is a device that uses gas to ionize glow discharge. When the neon glow discharge is turned on, the neon current is not more than 1mA, the starting voltage is between 1 10V, the stable voltage is tens of volts, and the service life is relatively long. Neon lights are characterized by high voltage and low current. Matters needing attention when using neon lights are to check whether the circuit connection and neon lights will leak electricity. If the neon lights are in good condition, they can be used normally. If the neon lamp is broken, don't use it, because it may have leaked out. If it is broken, it won't shine, so it will cause some rework, try to avoid various problems and better operate the function and effect of the neon lamp. The use of high-voltage neon lights is to pay attention to controlling the current and voltage range of neon lights, and whether the withstand voltage and service life of neon lights have changed after adding resistors. Neon lamp is a kind of gas discharge lamp and a new lighting industry. The so-called neon lamp is a lamp product that uses neon, an inert gas, to discharge and play a lighting role. Neon lights are widely used. Because its luminous color is mostly orange, it is widely used in neon lights of modern cities to dress up the city. A lamp made of neon gas filled in a vacuum tube can emit red light when current is applied, and its brightness varies with voltage. This light can penetrate smoke and is often used as a signal lamp. LED lights directly convert electric energy into light, while neon lights use gas to drive light. Neon lamps and LED lamps are similar in appearance and structure, and their products are widely used.
