IfcLampType

Definition from IAI: An IfcLampType is a type of device that is designed to emit light.

HISTORY: New entity in IFC 2x2 Addendum 1.

Use Definitions

An IfcLampType provides for all forms of lamp and its usage defines the parameters for one or more occurrences of IfcFlowTerminal.

Instances of IfcFlowTerminal that are defined as types of IfcLampType are connected via instances of IfcDistributionPort to an instance of IfcFlowTerminal that is defined as a type of IfcLightFixtureType.

Rendering using lighting data is achieved using light source entities within the presentation capabilities of IFC.

Property Set Use Definition:

The property sets relating to the IfcLampTypeare defined by the IfcPropertySet and attached by the IfcRelDefinesByType relationship. It is accessible by the inverse IsDefinedBy relationship. The following property set definitions specific to an IfcLampType are part of this IFC release:

Pset_LampTypeCommon: property set for properties that are common to all types of lamp installed within a light fixture, if available

Geometry Use Definitions

Representations of the type are defined as representation maps (at the level of the supertype IfcTypeProduct). These are assigned at the occurrence through the IfcShapeRepresentation.Item being an IfcMappedItem.
