Neonindikátorok

Neonindikátorok, often referred to as neon indicators or neon lights, are small gas-discharge lamps that produce light when an electric current passes through them. These lamps typically consist of a glass envelope filled with a low-pressure neon gas, along with two electrodes. When a sufficient voltage is applied across the electrodes, the neon gas inside the tube is ionized, causing it to emit a characteristic reddish-orange glow.

The operation of a neon indicator relies on the principle of gas discharge. The voltage applied must be high enough to overcome the ionization potential of the neon gas. Once ionization occurs, the gas becomes conductive, and a continuous electrical discharge is maintained. The intensity and color of the light can vary slightly depending on the gas mixture and pressure within the tube.

Neon indicators are widely used as visual indicators in electronic devices. They serve to signal the presence of power, indicate operational status, or act as simple on/off switches. Their low power consumption, long lifespan, and relatively low cost have made them a popular choice for a variety of applications, including power supply indicators on appliances, control panels, and older electronic equipment. While more modern LED indicators have become prevalent, neon indicators still hold a niche in certain applications due to their distinct glow and inherent simplicity.
