Lamp, Incandescent

Definition

An electric lamp in which a filament gives off light when heated to incandescence by an electric current.

Purpose

Incandescent lamps provide illumination by heating a filament until it glows, producing light. They have been widely used for general lighting purposes in homes, offices, and various other applications.

Examples of Use

• Residential lighting: Commonly used in household fixtures such as table lamps, ceiling lights, and wall sconces.
• Decorative lighting: Used in decorative fixtures and chandeliers for their warm light quality.
• Portable lighting: Incorporated in flashlights and other portable light sources.

Related Terms

• LED Lamp: A type of lamp that uses light-emitting diodes for illumination, known for its energy efficiency.
• CFL (Compact Fluorescent Lamp): A type of energy-saving light bulb that uses fluorescence to produce light.
• Halogen Lamp: A type of incandescent lamp that contains halogen gas to increase efficiency and lifespan.

Notes

• Incandescent lamps are less energy-efficient compared to LED and CFL lamps.
• They generate more heat, which can be a consideration in certain applications.
• Many countries have phased out or restricted the use of incandescent lamps in favor of more energy-efficient alternatives.
