LIGHTBULB Meaning and
Definition
-
A lightbulb is an artificial source of light consisting of a glass or plastic enclosure that contains a filament or other device that emits light when an electrical current is passed through it. The enclosure is often shaped like a bulb, hence its name. The primary purpose of a lightbulb is to provide illumination in homes, offices, and various other settings, replacing the need for natural sunlight during the darker periods of the day.
The filament inside a traditional incandescent lightbulb is usually made of tungsten, as it has a high melting point and is able to withstand the intense heat generated when an electrical current flows through it. As the electric current passes through the filament, it produces both heat and visible light. Compact fluorescent bulbs and LED bulbs are also common types of lightbulbs, providing more energy-efficient alternatives to traditional incandescent bulbs.
Lightbulbs are typically designed to fit into a socket, which connects to an electricity supply, allowing the bulb to be powered. They are available in various wattages and designs to suit different applications and intensities of lighting required. The light emitted by a lightbulb can be influenced by factors such as the shape of the enclosure, the filament material, and the color temperature desired.
Lightbulbs have revolutionized human society by extending the hours in which activities can be carried out and enhancing safety and comfort in indoor spaces. They have become an indispensable part of modern life, providing illumination in residences, commercial buildings, streetlights, vehicles, and a wide range of other applications.

Etymology of LIGHTBULB
The word "lightbulb" is a compound noun consisting of two parts: "light" and "bulb".
The term "light" traces its origins back to the Old English word "lēoht", which meant "brightness" or "shining". It has remained relatively unchanged in its meaning throughout English history.
The word "bulb" comes from the Latin word "bulbus", meaning "bulbous root" or "onion". This term was used to describe plant bulbs, which have a rounded shape. The word "bulb" was later adapted to describe various rounded objects, including the glass envelope of an electric light.
Therefore, "lightbulb" is a combination of "light" and "bulb" and refers to a device that produces light through the use of electricity within a glass enclosure.
