glow lamp

Definitions

Construction

  • A type of low-consumption electric discharge lamp whose light is produced close to the electrodes within an ionized gas. A glow lamp is often used as an indicating light.

Electronics

  • An electron tube which produces light when the inert gas it contains becomes ionized by an electric discharge passed between its two electrodes. The gas is at a low pressure, and the light is produced by a glow near the negative electrode. An example is a neon lamp.
