What are the main components of neon lights?

1. Glass tube

The main functions of the glass tube in the neon light are filling working gas, connecting two electrodes and transmitting visible light. Common neon glass tubes include bright tubes, powder tubes and color tubes.

2. Electrodes

Electrodes in neon lights are used to emit electrons and collect electrons and positive ions. They are made of metals that are resistant to positive ion bombardment, have a high melting point and are easy to emit electrons.

3. Mica sheet (or collar)

The main function of mica sheets in neon lights is to support electrodes, heat insulation and reduce cathode sputtering on the inner wall of the glass tube. The supporting electrode can prevent it from shifting, loosening and contacting the glass tube; heat insulation can prevent the glass tube from bursting; reducing the cathode sputtering on the inner wall of the glass tube can prolong the life of the lamp tube.

What is the role of the medium and high voltage transformer in neon lights?

It is a constant current device connected to the neon tube circuit, and it forms a complete set of neon lights with the tube. The electrical properties of glow discharge have the following characteristics: First, it requires higher ignition voltage and lower working voltage, and second, it has negative volt-ampere characteristics that make the discharge unstable. The use of magnetic flux leakage high-voltage transformers or electronic step-up transformers can provide up to 15V voltage to the lamp to make the lamp ignite. When the gas begins to discharge, the voltage will immediately drop to a constant value, maintaining the normal glow discharge of the lamp. a steady state.

What is the luminous principle of neon lights?

neon lights rely on the electrode heads at both ends of the light to ignite the rare gas in the lamp tube under a high-voltage electric field. Unlike ordinary light sources, they must burn tungsten wires to a high temperature to light up, causing a large amount of electric energy to be consumed in the form of heat energy. Therefore, with the same amount of electric energy, neon lights have higher outdoor lighting decoration of neon lights.

neon lights are made of glass tubes. After firing, the glass tubes can be bent into any shape, which has great flexibility. By selecting different types of tubes and filling them with different inert gases, neon lights can get colorful and multi-color light. Since neon lamps are cold cathode glow discharge, the service life of a qualified neon lamp can reach 20000-30000 hours.
