LIGHT BULB Meaning and
Definition
-
A light bulb is an electrical device that produces illumination by converting electrical energy into light. It is a type of lamp that typically consists of a glass or transparent plastic bulb containing a filament or a light-emitting diode (LED), along with a base and electrical connectors.
The filament, usually made of tungsten, is heated to a high temperature when an electric current passes through it, causing it to emit visible light. In incandescent light bulbs, the filament emits a warm glow due to the high temperature, while LED bulbs emit light through the movement of electrons in a semiconductor material.
Light bulbs come in various shapes and sizes, such as the common pear-shaped bulbs or more decorative options. The base of the bulb is the part that fits into a socket and can be screwed or pushed into place for electrical contact.
Light bulbs are widely used for indoor and outdoor lighting purposes in both residential and commercial applications. They have been an essential invention that revolutionized the way we illuminate our surroundings. However, advances in technology have led to the development of more energy-efficient options, such as compact fluorescent lamps (CFLs) and LED bulbs, which consume less electricity and have a longer lifespan compared to traditional incandescent bulbs.

Etymology of LIGHT BULB
The word "light bulb" is a compound word formed from two separate words: "light" and "bulb".
The word "light" originates from the Old English word "leoht", which itself is derived from the Proto-Germanic word "leuhtam". This Proto-Germanic word is thought to have a common origin with the Old Norse word "ljóss" and the Gothic word "liuhaþ".
"Bulb", in this context, refers to the rounded glass envelope or container that holds the filament and other parts of the electric lamp. "Bulb" originated from the Latin word "bulbus", meaning a swollen or round shape. It was borrowed from Latin into Old French as "bulbe" and later into Middle English.
