Neon lights have so many colors

 Light tube type neon lights filled with neon gas, the neon light emits red light, filled with argon can make it emit light blue light, filled with helium can make it emit reddish light, mercury vapor can make it emit purple light; fluorescent neon lights are filled Argon and mercury, neon lights emit blue, yellow and other light. Both types of neon lights rely on the stimulated radiation of the working gas atoms in the tube to emit light.

Sometimes people mix them together and put them in neon lights to make them emit colorful lights.

 

Helium: pink

Neon gas: red, used for aviation and navigation as indicator light

Argon gas: purple blue

Krypton gas: full of krypton gas, which can increase the luminous flux output by 10%

Xenon: strong light, used for lighting in large public places (squares, stadiums, airports, etc.)

 

The principle of neon light is in a closed glass tube filled with neon, helium, argon and other gases. Two metal electrodes are installed at both ends of the tube. The electrodes are generally made of copper. The electrode leads are connected to the power circuit and equipped with a high-voltage transformer. Apply a voltage of 10~15kV to the electrode. Since the gas in the tube is composed of countless molecules, the molecules and atoms are neutral under normal conditions. Under the action of high voltage, a small amount of free electrons move to the anode, and the rapid dissociation of gas molecules stimulates the electrons to accelerate, which makes the gas in the tube conduct electricity and emit a color glow (also known as rainbow light). The luminous color of the neon light principle is related to the gas used in the tube and the color of the tube; the neon light principle will emit golden light if neon gas is installed in a light yellow tube, and yellow-white light if neon gas is installed in a colorless transparent tube . The principle of neon light is to produce different colors of light, it is necessary to use many different color tubes or to fill the neon tube with different gases, not mixed.

 

The neon light screen is composed of a light tube that is always on and a scanning tube that is dynamically illuminated. It can be set to be a beating scan, a gradual scan, and a mixed color scan. The scanning tube is controlled by a scanner equipped with microcomputer chip programming. The scanning tube lights up or goes off according to the programmed program, forming a pair of flowing pictures, like a rainbow in the sky, like a galaxy on earth, and even more like a dream world. It is fascinating and fascinating. Unforgettable. Therefore, neon lights are an economical and practical form of advertising with less investment, strong effects.

How to make neon lights in other colors

图片
  If you want to make   neon lights   of other colors, you can ask green, yellow, blue, and white phosphors to help. For example, apply blue phosphor to the inner wall of the glass tube, bend the glass tube into the required characters or patterns, install electrodes, and evacuate the air in the glass tube, and then put neon gas into it. It's a pink neon sign. If you put argon gas and mercury in a tube coated with blue phosphor, it becomes a bright blue neon light. If neon gas is placed in a tube coated with green phosphor, it will be orange-red; if neon gas is changed to argon and mercury, it will be transformed into a green neon light. Therefore, neon lights of other colors can be made as you like. Neon lights not only embellish shop windows, signs and billboards, but also beautify the city, it is also an important sign light!

How many kinds of neon light high-voltage lines are there?

图片
  Ordinary high-voltage wires, namely plastic high-voltage wires, are cheap, but plastics are prone to aging. Soon after they are used outdoors, the plastics will aging and cause fire, etc., and their safety is poor. Silicone rubber insulated high-voltage wire is an ideal neonlightconnection wire with strong safety and good reliability.   Neon lights  are the same as other commodities, with great differences in varieties, specifications, and quality. When users choose a neon light production unit, they must also understand their production strength, processing technology and after-sales service.
