Apakah tanda Lampu Neon LED diperbuat daripada?
What is neon?
Color tube (colored glass) in the glass factory production that has been added yellow, merah, 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. Dengan memilih jenis tiub yang berbeza dan mengisinya dengan gas lengai yang berbeza, neon boleh menghasilkan warna-warni, 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.
Lampu neon LED
Sejak kemunculan lampu neon, after a hundred years of unfailing. It is a special low pressure cold cathode glow discharge electric light source, dan berbeza daripada yang lain seperti lampu pendarfluor, lampu natrium tekanan tinggi, lampu halida logam, lampu merkuri, 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, manakala lampu neon mengeluarkan cahaya biru dan kuning. 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, lampu neon mempunyai ciri-ciri berikut:
Pertama, kecekapan tinggi
Lampu neon bergantung pada elektrod di kedua-dua hujung cahaya dalam medan voltan tinggi akan menjadi gas lengai dalam tiub, ia berbeza daripada sumber cahaya biasa mesti membakar wayar tungsten kepada suhu tinggi kepada cahaya, mengakibatkan sejumlah besar tenaga elektrik dalam bentuk tenaga haba digunakan, Oleh itu, dengan jumlah tenaga elektrik yang sama, neon mempunyai kecerahan yang lebih tinggi.
dua, suhu rendah, penggunaan tidak dihadkan oleh iklim
Lampu neon kerana sifat katodnya yang sejuk, suhu tiub adalah di bawah 60°C apabila ia berfungsi, jadi ia boleh diletakkan di udara terbuka dalam cahaya matahari dan hujan atau di dalam badan.
Penggunaan tenaga yang rendah
Dalam era inovasi teknologi yang berterusan, 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, daripada 56 watt per meter lampu ke 12 watt per meter lampu.
Empat, panjang umur
Lampu neon dalam kerja berterusan di bawah keadaan elektrik berterusan, kehidupan lebih daripada 10,000 Jam, kelebihan ini sukar dicapai mana-mana sumber cahaya elektrik lain.
lima, pengeluaran yang fleksibel, warna yang pelbagai
Neon diperbuat daripada tiub kaca yang boleh dinyalakan dan dibengkokkan ke dalam sebarang bentuk dengan fleksibiliti yang hebat. Dengan memilih jenis tiub yang berbeza dan mengisinya dengan gas lengai yang berbeza, neon boleh menghasilkan warna-warni, cahaya pelbagai warna.
Enam, dinamik, kesan yang baik, ekonomi dan praktikal
Skrin cahaya neon oleh tiub cahaya mantap dan komposisi tiub pengimbasan cahaya dinamik, boleh ditetapkan untuk melompat imbasan, imbasan secara beransur-ansur, mixed color change seven color scan. Scanning tube by equipped with microcomputer chip programming scanner control, tiub pengimbasan mengikut lampu program yang diprogramkan atau padam, membentuk aliran gambar, seperti pelangi di langit, seperti Bima Sakti, lebih seperti dunia mimpi, menarik, unforgettable. Therefore, neon ialah satu bentuk pengiklanan dengan pelaburan yang kurang, kesan kuat dan utiliti ekonomi
