A neon lamp glows brightly in the window of a small shop.

Definition

Noun: A neon lamp is a type of electric light. It consists of a glass tube containing neon gas at low pressure. When a high-voltage electrical current is passed through the gas, it produces a bright, glowing light, typically of a reddish-orange color.

Usage

The term neon lamp specifically refers to the lighting device itself. It is used to describe the object, its function, or its characteristic light. * A neon lamp is often used for signs and decorative lighting. * The scientist used a neon lamp to demonstrate the principles of gas discharge. * The glow from the neon lamp illuminated the street corner.

Advanced Usage
  • As a component: In electronics, a small neon lamp can be used as an indicator light or a voltage regulator due to its specific ignition and operating voltages.
    • The old radio had a small neon lamp that lit up when the device was powered on.
  • In physics/chemistry contexts: The term is used to describe a tool for demonstrating atomic emission spectra or gas discharge phenomena.
    • The characteristic red light of a neon lamp is caused by excited neon atoms returning to a lower energy state.
Variants and Related Words
  • Neon light: A very common synonym, often used interchangeably, though it can sometimes refer more broadly to any brightly colored gas-discharge tube lighting (even if it contains gases other than neon to produce different colors).
  • Neon tube: Emphasizes the physical, tubular shape of the lamp.
  • Neon sign: Refers specifically to a neon lamp or assembly of lamps used for advertising or display purposes.
  • Gas-discharge lamp: The general technical category which includes neon lamps, fluorescent lights, and sodium-vapor lamps.
