7.4.2.16.1 Semantic definition

The IfcLampTypeEnum defines the range of different types of lamp available.

7.4.2.16.2 Type values

Type Description
COMPACTFLUORESCENT

A fluorescent lamp having a compact form factor produced by shaping the tube.

FLUORESCENT

A typically tubular discharge lamp in which most of the light is emitted by one or several layers of phosphors excited by ultraviolet radiation from the discharge.

HALOGEN

An incandescent lamp in which a tungsten filament is sealed into a compact transport envelope filled with an inert gas and a small amount of halogen such as iodine or bromine.

HIGHPRESSUREMERCURY

A discharge lamp in which most of the light is emitted by exciting mercury at high pressure.

HIGHPRESSURESODIUM

A discharge lamp in which most of the light is emitted by exciting sodium at high pressure.

LED

A solid state lamp that uses light-emitting diodes as the source of light.

METALHALIDE

A discharge lamp in which most of the light is emitted by exciting a metal halide.

OLED

A solid state lamp that uses light-emitting diodes as the source of light whose emissive electroluminescent layer is composed of a film of organic compounds.

TUNGSTENFILAMENT

A lamp that emits light by passing an electrical current through a tungsten wire filament in a near vacuum.

USERDEFINED

User-defined type.

NOTDEFINED

Undefined type.

Last change: Improve definition split (#876) * bring back headers headers were previously removed by mistake, now bringing them back * add new lines and rename the tag add the word 'short' in it * unify newlines make exactly one newline before and two after the tag * resolving typos Because bringing back headers required to go back in time to previous version, I'm now re-resolving the issues: #861, #860, #856 by ArturTomczak on 2024-07-16T16:07:28+02:00
