What Is A Neon Sign And The Material Of A Neon Sign？

1. What does Jia Hongdeng mean?

Leihongdeng is the beautician of the city. Whenever the tomb falls at night, colorful Leihongdeng can be seen everywhere, showing the charm of the city. So what is a neon sign?

Neon lamp refers to an electrified glass tube or bulb filled with thin neon gas or other rare gases. It is a cold cathode gas discharge lamp, usually used for advertising signs, urban decoration, etc. A thunderbolt tube is a sealed glass tube with electrodes at both ends, filled with some low pressure gas.

A voltage of several thousand volts is applied to the electrodes, which ionizes the gas in the tube causing it to emit light, the color of which depends on the gas in the tube.

Neon lights should actually be called neon lights (neonlight), neon is a transliteration of neon, and now people have used "neon lights" as a special term.

2. Who Invented Xiaohong Lantern

The heavy rainbow was discovered accidentally by the British chemist Ramsay in an experiment.

One night in June 1898, Ramsey and his assistants were conducting experiments in the laboratory to check whether a rare gas was conductive. They injected a rare gas into a vacuum glass tube, and then sealed it in a vacuum. The two metal electrodes in the glass tube were connected to a high-voltage power supply, and then it was found that the rare gas injected into the vacuum tube not only began to conduct electricity, but also emitted an extremely beautiful red light. Ramhan made this rare gas that can conduct electricity and emit red light Named Neon (neon). Later, this kind of lamp that energizes the gas to emit light is called neon lamp (neonlight), that is, neon lamp.

Classification of materials for neon signs

1. According to the specifications of neon material, it can be divided into: 6mm, 7mm, 8mm, 9mm, 10mm, 12mm, 15mm, 18mm,
20mm and other specifications of different thickness.

2. According to the different materials of fluorescent powder coated in the heavy rainbow tube, it can be divided into: ordinary fluorescent powder and three primary color fluorescent powder.

At present, many neon tubes are sprayed with ordinary fluorescent powder, which is relatively cheap and can basically meet the requirements for various colors. trichromatic fluorescence

Phosphor powder, also known as dilute phosphor, has better brightness, chroma, and freshness than ordinary phosphor.

3. According to the different glass materials, it can be divided into: sodium glass tube, lead glass tube and colored glass tube.

4. According to the different spraying process of phosphor powder, it can be divided into water coating and glue coating.
The water coating process is to spray alcohol and ketone solvent mixed phosphor powder on the inner wall of the lamp tube, and then let it dry naturally. The glue coating process is to use the glue liquid to mix the fluorescent powder into the

Spraying and then drying in an oven, its viscosity and firmness are much better than water-coated powder tubes.
