EcoLight: My Guide to Greener Home Lighting

CortezFenn

An electric mild, lamp, or mild bulb is an electrical machine that produces mild from electricity. It is the most common type of artificial lighting. Lamps usually have a base manufactured from ceramic, steel, glass, or plastic that secures them in the socket of a gentle fixture, which is also generally referred to as a 'lamp.' The electrical connection to the socket could also be made with a screw-thread base, two metal pins, two metallic caps or a bayonet mount. The three most important categories of electric lights are incandescent lamps, which produce gentle by a filament heated white-scorching by electric present, gasoline-discharge lamps, which produce mild by means of an electric arc through a gas, similar to fluorescent lamps, and LED bulbs for home lamps, which produce gentle by a move of electrons across a band gap in a semiconductor. The vitality effectivity of electric lighting has considerably improved since the primary demonstrations of arc lamps and incandescent mild bulbs in the nineteenth century.
