Neon Glow Lamp Life Is Normally Higher Than Fluorescent And Incandescent
Nov 01, 2017

Neon lights are the city's beautician, whenever the night falls, the lanterns, the colorful neon lights put the city dress up particularly beautiful. So, how is the neon lights invented? It is said that the neon is the British chemist Ramsey in an experiment by chance found. It was one night in June 1898, and Ramsey and his assistants were experimenting in the laboratory to examine whether a rare gas was conductive. Ramsey put a rare gas into the vacuum glass tube, and then sealed in the vacuum glass tube in the two metal electrodes connected to the high-voltage power supply, attentively observe whether the gas can be conductive.

Suddenly, an unexpected phenomenon occurred: the rare gas injected into the vacuum tube not only began to conduct electricity, but also issued a very beautiful red light. This magical red light surprised Ramsey and his aides, and they opened the door to the neon world. Ramsey named this rare gas, which was conductive and emitting red light, neon. Later, he continued to other gases and the characteristics of the issue of colored light experiments, have found that xenon can send white light, argon can send blue light, helium can send yellow light, krypton can send dark blue light ... ... different Of the gas can send a different shade, colorful, like a beautiful rainbow sky. Neon is also named after this.

Manufacturing neon way, is the use of low melting point of sodium - calcium silicate glass lamp, according to the need to design a different pattern and text, with a torch for processing, and then sintering the electrode, and then vacuum pump, and according to the required color Filled with different rare gases and made. Modern neon lights more refined, and some of the glass tube bent into a variety of folding shape, made more moving graphics; and some in the lamp wall coated with phosphor, the color is more bright and colorful; some neon lights installed Automatic ignition, so that all kinds of light times the first off, add radiance and beauty to make the city night become colorful.

Since the advent of neon lights since 1910, after a hundred years. It is a special low-pressure cold cathode glow discharge light source, and is different from other arc lamps such as fluorescent lamps, high pressure sodium lamps, metal halide lamps, mercury lamps, incandescent lamps and so on. Neon lights are filled with low-pressure inert gas in the glass tube, in the high-voltage electric field under the cold cathode glow discharge and light. Neon light color is determined by the characteristics of the inert gas into the spectral characteristics: light tube neon filled neon, neon light red; fluorescent neon filled with argon and mercury, neon blue, yellow and other light, these two Large class of neon lights are dependent on the work of the gas atom Attenuation radiation.

Neon lights according to the glass tube wall of the different powder, the file is divided into three types: the first is the glass wall is not coated with any phosphor, direct use of colorless transparent glass tube, usually called Ming; In the transparent glass tube coated with phosphor, we call it powder tube; the third is the use of stained glass tube, and in the glass tube wall evenly coated with phosphor, we call it CPT.

Neon life is normal in the case of fluorescent lamps and incandescent lamps, to achieve this level must be done three points: 1, the production staff level is too strong, the exhaust personnel bombardment deodily, thoroughly; 2, start its transformer must not overload ; 3, the installation staff detailed and reasonable installation; as long as the above requirements, the practice proved that the life of neon lights is higher than the fluorescent and incandescent.
