The development history of neon lights is as follows:

Neon light is derived from the English word "neon light", which is actually a transliteration of "neon". People have already used "neon light" as a specialized word.

The development of neon lights can be traced back to the study of gas discharge by British physicist and chemist Faraday. When an electric current passes through a gas containing a small amount of positive and negative ions, it is affected by ultraviolet radiation, cosmic rays, and trace amounts of radioactive substances. Under a sufficiently high external voltage, it moves and collides with neutral gas molecules, causing ionization of the neutral molecules and doubling the number of ions. When an electric current passes through a gas, there is also a phenomenon of luminescence, known as glow discharge. The color of its luminescence varies depending on the gas being filled. Faraday's theory and his achievements in experiments have laid a solid foundation for the development of neon light technology.

Neon lights originated in France. The diameter of the lamp body glass tube used at that time was 45 millimeters. The glass tube was first bent into the required text or pattern, and then powered by a transformer with a voltage of over 10000 volts to make it emit light. At that time, the electrodes at both ends of the lamp tube were made of graphite, filled with nitrogen or carbon dioxide gas inside. The former would emit red light, while the latter would emit white light. Due to the reactivity of these two gases, they easily react with graphite electrodes. The graphite splashed out from the cathode quickly forms a black thin film layer on the inner wall of the glass tube and absorbs a large amount of gas filled into the lamp tube, causing the inflation pressure of the lamp tube to quickly decrease, resulting in a short lifespan of the neon lamp. At that time, in order to solve this problem, a special electromagnetic valve was added to the neon light tube, and a certain amount of gas was replenished into the lamp after the neon light was used for a period of time. However, this approach did not fundamentally overcome the above shortcomings. Therefore, this type of lamp not only has a short lifespan, complex manufacturing process, but also is expensive and difficult to popularize.

Between 1907 and 1910, scientists Claude and Lind invented liquid air distillation. By using this invention, a certain amount of inert gas is injected into the neon light, which significantly slows down the consumption rate of gas inside the lamp tube and enriches the color, producing colors such as red, green, blue, and yellow. On the eve of World War II, materials for photoluminescence were developed. This material not only emits light of various colors, but also has high luminous efficiency, which we call fluorescent powder. After the application of fluorescent powder in the production of neon lights, the brightness of the neon lights has not only been significantly improved, but the color of the lamp tubes has also become more vibrant and varied, while simplifying the lamp making process. After the end of World War II, neon lights experienced rapid development.

Neon lights can be classified into three types based on the different powders applied to the inner walls of their glass tubes: the first type is the use of colorless and transparent glass tubes without any fluorescent powder on the inner walls of the glass tubes, commonly known as transparent tubes; The second type is coated with fluorescent powder on the inner wall of transparent glass tubes, which we call powder tubes; The third method is to use colored glass tubes and evenly coat the inner wall of the glass tube with fluorescent powder, which we call color tubes.

The lifespan of neon lights is higher than that of fluorescent and incandescent lights under normal circumstances. To achieve this level, three points must be achieved: 1. The production personnel must have a strong level of proficiency, and the exhaust personnel should bombard and remove air properly and thoroughly; 2. The transformer that starts it must not be overloaded; 3. The installation personnel carefully and reasonably install; As long as the above requirements are met, practice has proven that the lifespan of neon lights is higher than that of fluorescent and incandescent lights.

The current development of neon lights:

In the neon light market, there is a mix of good and bad, and only 30% of the market consists of units with business licenses to undertake projects. These units have independent design, production, and installation capabilities, good reputation, product quality, and proper maintenance, making them the preferred units for users.

The second type is affiliated with other units without a business license. These units lack strong professionalism, product quality is not guaranteed, and maintenance is not in place in the later stage.

The third type is leather bag companies, which have no credentials, reputation, or ability. They switch places after firing a gun, and product quality and post maintenance cannot be discussed at all.

Neon lights are a highly specialized industry, and the products of legitimate units have good quality and long lifespan. It is precisely the second and third types of companies that disrupt the neon light market, giving users the impression that neon lights are prone to breakage. In fact, the lifespan of neon lights is longer than that of fluorescent lights. For your benefit, please choose a licensed, capable, and reputable unit.

Previously, almost all neon light manufacturing enterprises used ordinary glass tubes and electrodes. With the increasing demand for products, high lead glass tubes, ceramic ring electrodes, three primary color powder tubes, and gradient rainbow neon lights are becoming more and more widely used in people's lives, making their lives more exciting and beautiful.

Due to the fact that neon tubes are usually made of glass material! The production is relatively complex and has the disadvantage of being fragile! Due to the use of high-voltage transformers, there is often some interference with surrounding communication equipment. In today's technologically advanced world. Gradually replace with multi-color LEDs. Compared to others, it is more energy-efficient and convenient to install.
