An electric lamp is a source of optical radiation produced in
the result of conversion of electrical energy into light.
Thermal light sources
An incandescent lamp is an electric lamp in which light is emitted by a body,
heated as a result of passing through the non-electric current. As the filament body, a spiral of tungsten-based alloys is mainly used.
Halogen bulb is an incandescent lamp whose luminous body is inside a bulb filled with an inert gas, halogens or their compounds.
Discharge light sources
A discharge lamp is an electric lamp in which light arises in
the result of an electric discharge in a gas, a vapor of a metal gas mixture of gas with vapors.
A metal halide lamp is a discharge lamp in which light is produced by radiation
a mixture of metal vapors and decomposition products of metal halides.
A fluorescent lamp is a discharge lamp in which light is emitted in the main
layer of a luminescent substance excited by ultraviolet radiation of an electric discharge.
A discharge lamp is a discharge lamp in which an electric discharge
occurs in the gas.
Neon lamp - gas discharge lamp with neon.
Xenon lamp - gas discharge lamp with xenon.
The helium lamp is a gas-discharge lamp with helium.
A parabolic lamp is a discharge lamp in which light is produced primarily
radiation of metal vapors.
The mercury lamp is a vapor lamp in mercury vapor.
The sodium lamp is a vapor lamp in sodium vapor.
A fluorescent lamp-an incandescent lamp or a gas-discharge lamp, whose light
the spectral composition approaches daylight.
Semiconductor light sources
LED (light-emitting diode, LED, light-emittingdiode) - a light source that creates optical radiation when passing a direct current through the transition of a semiconductor device.
LED module - assembly of two or more LEDs with a complete set
electrical, optical, mechanical and thermal components without a control device.
LED lamp - LED module, equipped with a control device and
standard plinth.
