Description Class LightScene

INTENTION

This class provides all definitions concerning a light scene for an arbitrary room. These are w.r.t. the DIC document:

• a name,
• a value of the light intensity of the ambient light of a room,
• an ordered list containing the installed lamps. The list defines the order in which the control system has to use the lamps to reach the given ambient light value. Since this list always consists of two entries we model this list by two functions firstAmbientIlluminaire and secondAmbientIlluminaire.

Aspects concerning a light scene of an office are presented in the derived description class LightSceneOffice.
