Incandescent light bulb

incandescent lampfilamentincandescent light
Lamps are commonly called light bulbs; for example, the incandescent light bulb. The three main categories of electric lights are incandescent lamps, which produce light by a filament heated white-hot by electric current, gas-discharge lamps, which produce light by means of an electric arc through a gas, and LED lamps, which produce light by a flow of electrons across a band gap in a semiconductor. English chemist Humphry Davy developed the first incandescent light in 1802, followed by the first practical electric arc light in 1806.
An incandescent light bulb, incandescent lamp or incandescent light globe is an electric light with a wire filament heated to such a high temperature that it glows with visible light (incandescence).

Light fixture

luminairelampdesk lamp
Lamps usually have a base made of ceramic, metal, glass, or plastic, which secures the lamp in the socket of a light fixture.
A light fixture (US English), light fitting (UK English), or luminaire is an electrical device that contains an electric lamp that provides illumination.

Light

An electric light is a device that produces visible light from electric current.
With the development of electric lights and power systems, electric lighting has effectively replaced firelight.

An LED lamp or LED light bulb is an electric light for use in light fixtures that produces light using one or more light-emitting diodes (LEDs).

Arc lamp

English chemist Humphry Davy developed the first incandescent light in 1802, followed by the first practical electric arc light in 1806.
The carbon arc light, which consists of an arc between carbon electrodes in air, invented by Humphry Davy in the first decade of the 1800s, was the first practical electric light.

Lighting

illuminationartificial lightartificial lighting
It is the most common form of artificial lighting and is essential to modern society, providing interior lighting for buildings and exterior light for evening and nighttime activities.
Commonly called 'light bulbs', lamps are the removable and replaceable part of a light fixture, which converts electrical energy into electromagnetic radiation.

Electricity

Electricity's extraordinary versatility means it can be put to an almost limitless set of applications which include transport, heating, lighting, communications, and computation.

Lantern

Battery-powered light is often reserved for when and where stationary lights fail, often in the form of flashlights or electric lanterns, as well as in vehicles.
Examples are glass-pane enclosed street lights, or the housing for the top lamp and lens section of a lighthouse.

Candle

Before electric lighting became common in the early 20th century, people used candles, gas lights, oil lamps, and fires.
Before the invention of electric lighting, candles and oil lamps were commonly used for illumination.

Xenon arc lamp

A xenon arc lamp is a highly specialized type of gas discharge lamp, an electric light that produces light by passing electricity through ionized xenon gas at high pressure.

Light pollution

light-pollutedglarelight
Low-pressure sodium lights are favoured for public lighting by astronomers, since the light pollution that they generate can be easily filtered, contrary to broadband or continuous spectra.

Electric arc

The three main categories of electric lights are incandescent lamps, which produce light by a filament heated white-hot by electric current, gas-discharge lamps, which produce light by means of an electric arc through a gas, and LED lamps, which produce light by a flow of electrons across a band gap in a semiconductor.
A similar situation may occur when a lightbulb burns out and the fragments of the filament pull an electric arc between the leads inside the bulb, leading to overcurrent that trips the breakers.

Plasma (physics)

The ensuing arc produces a white-hot plasma between the rod tips.

Gas-discharge lamp

The three main categories of electric lights are incandescent lamps, which produce light by a filament heated white-hot by electric current, gas-discharge lamps, which produce light by means of an electric arc through a gas, and LED lamps, which produce light by a flow of electrons across a band gap in a semiconductor.
A high-intensity discharge (HID) lamp is a type of electrical lamp which produces light by means of an electric arc between tungsten electrodes housed inside a translucent or transparent fused quartz or fused alumina arc tube.

Color temperature

Different types of lights have vastly differing efficacies and color of light.
Color temperature may also be a factor when selecting lamps, since each is likely to have a different color temperature.

Edison screw

Incandescent bulbs and their retrofit replacements are often specified as "A19/A60 E26/E27", a common size for these kind of light bulbs.
Edison screw (ES) is a standard lightbulb socket for electric light bulbs.

A-series light bulb

Incandescent bulbs and their retrofit replacements are often specified as "A19/A60 E26/E27", a common size for these kind of light bulbs.
The A-series light bulb is the "classic" glass light bulb shape that has been the most commonly used type for general lighting service (GLS) applications since the early 20th century.

Phase-out of incandescent light bulbs

Banning of incandescent light bulbsphased outban on incandescent light bulbs
Incandescent bulbs are being phased out in many countries due to their low energy efficiency.
In December 2007, the federal government enacted the Energy Independence and Security Act of 2007 (EISA), which set maximum power consumption requirements for all general-service light bulbs producing 310–2600 lumens of light.

Stage lighting

They remained in use in limited applications that required these properties, such as movie projectors, stage lighting, and searchlights, until after World War II.
The first are the specifics of the lamp, reflector and lens assembly.

Street light

The total amount of artificial light (especially from street light) is sufficient for cities to be easily visible at night from the air, and from space.
Many street light controllers also come with traffic sensors to manage the lux level of the lamp according to the traffic and to save energy by decreasing lux when there is no traffic.
