What are LED Neon Light signs made of?
What is neon?
Color tube (colored glass) in the glass factory production that has been added yellow, red, blue, 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. Sa pamamagitan ng pagpili ng iba't ibang uri ng mga tubo at pagpuno ng mga ito ng iba't ibang mga inert gas, ang neon ay maaaring makabuo ng isang makulay, 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 mga ilaw
Simula nang dumating ang mga neon lights, after a hundred years of unfailing. It is a special low pressure cold cathode glow discharge electric light source, at naiiba sa iba tulad ng fluorescent lamp, mataas na presyon ng sodium lamp, metal halide lampara, 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, habang ang neon lights ay naglalabas ng blue at 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 ay may mga sumusunod na katangian:
Una, mataas na kahusayan
Neon lights umaasa sa mga electrodes sa parehong dulo ng liwanag sa mataas na boltahe field ay magiging inert gas sa tubo, ito ay naiiba mula sa ordinaryong pinagkukunan ng ilaw ay dapat magsunog ng tungsten wire sa mataas na temperatura sa liwanag, na nagreresulta sa isang malaking halaga ng electric enerhiya sa anyo ng enerhiya ng init ay natupok, kaya nga, sa parehong dami ng electric energy, mas mataas ang brightness ni neon.
Dalawa, mababa ang temperatura, ang paggamit ay hindi pinaghihigpitan ng klima
Neon lamp dahil sa malamig na cathode property nito, ang temperatura ng tubo ay mas mababa sa 60o C kapag ito ay gumagana, kaya pwede itong ilagay sa open air sa sikat ng araw at ulan o sa katawan.
Mababang pagkonsumo ng enerhiya
Sa panahon ng patuloy na teknolohikal na makabagong ideya, 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, mula sa 56 watts per meter ng lamp to 12 watts bawat metro ng lampara.
Apat na, mahabang buhay
Neon lights sa patuloy na trabaho sa ilalim ng kondisyon ng patuloy na kuryente, buhay ng higit sa 10,000 mga oras, bentahe na ito ay mahirap upang makamit ang anumang iba pang mga electric light source.
Lima, nababaluktot na produksyon, iba't ibang kulay
Ang Neon ay gawa sa mga tubo ng salamin na maaaring ma fired at baluktot sa anumang hugis na may mahusay na kakayahang umangkop. Sa pamamagitan ng pagpili ng iba't ibang uri ng mga tubo at pagpuno ng mga ito ng iba't ibang mga inert gas, ang neon ay maaaring makabuo ng isang makulay, maraming kulay na ilaw.
Anim na, dynamic na, magandang epekto, pang ekonomiya at praktikal
Neon light screen sa pamamagitan ng steady light tube at dynamic light scanning tube komposisyon, pwedeng set sa jump scan, unti unting pag scan, mixed color change seven color scan. Scanning tube by equipped with microcomputer chip programming scanner control, scanning tube ayon sa programmed program light or off, pagbuo ng isang daloy ng mga larawan, parang bahaghari sa langit, tulad ng Milky Way, mas parang mundo ng panaginip, nakakabighani, unforgettable. Therefore, neon ay isang anyo ng advertising na may mas kaunting pamumuhunan, malakas na epekto at pang ekonomiyang utility
