What is neon?
Tuba u boji (staklo u boji) in the glass factory production that has been added yellow, Crvena, plava, green and other pigments, are manually blown, so the price is high and the diameter error is large. Neon light is a long discharge cold anode luminous discharge device, the use of short-wave ultraviolet excitation phosphors (such as tungstate, borate, silicate, phosphate phosphors). Its luminous principle is low pressure mercury discharge produces millimeter ultraviolet light, and then from millimeter ultraviolet light excitation of various phosphors, so as to obtain a number of colors of neon light. Neon principle in the closed glass tube, filled with neon, helium, argon and other gases, the two ends of the tube are equipped with two metal electrodes, electrodes are generally made of copper material, electrode lead access to the power supply circuit, with a high voltage transformer, 10~ voltage on the electrode. Because the gas inside the tube is made up of countless molecules, the molecules and atoms are neutral under normal conditions. Under the action of high voltage, a small number of free electrons move to the anode, and the rapid dissociation of gas molecules stimulates the accelerated movement of electrons, so that the gas in the tube conducts electricity and gives out color glow (also known as rainbow light). The luminous color of neon principle is related to the gas used in the tube and the color of the lamp; Neon principle Neon gas glows golden if it is filled in a yellowish tube, or yellow and white if it is colorless and transparent. Neon principle To produce different colors of light, you use many different colors of light tubes or fill them with different gases. Neon is made of glass tubes that can be fired and bent into any shape with great flexibility. By choosing different types of tubes and filling them with different inert gases, the neon can produce a colorful, multi-colored light. The construction and principle of neon lights are not complicated. In the glass tube closed at both ends, two electrodes are installed, the air in the tube is drawn out, and then more than ten thousand volts of high voltage direct current is passed between the two electrodes. The thin air in the tube will ionize, produce discharge phenomenon, and give out light. If the air is pumped out and small amounts of different inert gases or mercury vapors are filled inside the tubes, the lights will take on different colors: when filled with neon, they will glow orange-red.
LED neon lights
Since the advent of neon lights, after a hundred years of unfailing. It is a special low pressure cold cathode glow discharge electric light source, and is different from other such as fluorescent lamp, high pressure sodium lamp, metal halide lamp, mercury lamp, incandescent lamp and other arc lamp. Neon lights are produced by a cold cathode glow discharge under a high voltage field of inert gas filled in a glass tube. The color of the neon lamp is determined by the spectral characteristics of the inert gas. Fluorescent neon lights are filled with argon and mercury, while neon lights emit blue and yellow light. These two types of neon lights are generated by excited radiation from the atoms of the working gas in the tube. Compared with other electric light sources, neon lights have the following characteristics:
Prvi, high efficiency
Neon lights rely on the electrodes at both ends of the light in the high voltage field will be inert gas in the tube, it is different from the ordinary light source must burn tungsten wire to high temperature to light, resulting in a large amount of electric energy in the form of heat energy is consumed, therefore, with the same amount of electric energy, neon has a higher brightness.
Two, the temperature is low, the use is not restricted by climate
Neon lamp because of its cold cathode property, the tube temperature is below 60°C when it works, so it can be placed in the open air in sunlight and rain or in the body.
Low energy consumption
In the era of continuous technological innovation, the manufacturing technology of neon lights and the technical level of related parts are constantly improving. The application of new electrodes and electronic transformers has greatly reduced the power consumption of neon lights, from 56 watts per meter of lamp to 12 watts per meter of lamp.
Four, dug život
Neon lights in continuous work under the condition of continuous electricity, life of more than 10,000 sati, this advantage is difficult to achieve any other electric light source.
Five, flexible production, diverse colors
Neon is made of glass tubes that can be fired and bent into any shape with great flexibility. By choosing different types of tubes and filling them with different inert gases, the neon can produce a colorful, multi-colored light.
Six, dynamic, good effect, economic and practical
Neon light screen by the steady light tube and dynamic light scanning tube composition, can be set to jump scan, gradual scan, mixed color change seven color scan. Scanning tube by equipped with microcomputer chip programming scanner control, scanning tube according to the programmed program light or off, forming a flow of pictures, like a rainbow in the sky, like the Milky Way, more like a dream world, fascinating, unforgettable. Therefore, neon is a form of advertising with less investment, strong effect and economic utility
