ReluxDesktop is a powerful and intuitive application for the simulation of artificial light
and daylight.
ReluxDesktop allows you to plan individual rooms, entire floors, industrial halls or outdoor
areas such as car parks, sports facilities and roads – all in just one piece of
software.
Calculation of absolute values, national and international standards, compatible with CAD and
BIM systems. ReluxDesktop supports the import and export of different formats. You can
also plan sensors using ReluxDesktop – the only software on the market that allows you
to do so. ReluxDesktop makes the planning of emergency lighting particularly easy and
accurate.
Quick and easy calculation of lighting values in less than 2 minutes using
ReluxExpress.
The programme can be extended to meet the users’ needs through add-ons and
plug-ins.
Import / export numerous formats: Import (ies, ldt, ROLF, gbXML, ReCad, 3ds, dxf, dwg,
xlsx, PDF, geolocations from GoogleMaps), Export (dwg, ReCad,, xlsx)
Interface to BIM: A bidirectional interface to Revit enables loss-free communication with the
ReluxDesktop lighting design programme and the ReluxCAD for Revit Add-on.
ReluxDesktop can be downloaded free of charge and used for personal, educational and
commercial purposes. Thanks to the support of industry partners, the software is available free
of charge.
A large number of luminaires and sensors are provided by RELUX members free of charge for
planning purposes. Luminaires from non-Relux members are displayed anonymously and can be
displayed by purchasing a ThirdParty
licence.
Relux supports lighting designers with a wide range of training and further education courses – from beginner to professional.
Select your environment or room and define its mass and shape. Use CAD drawings, gbXML or Geolocations to create the scene. Or import the room using the Metaroom app.
ReluxNet provides you with over 1 million items for your planning, including luminaires, sensors and 3D objects. You can easily add the files to your ReluxDesktop project with one click.
You can place the selected luminaires and sensors in the room or have them placed
automatically and add windows, doors, objects and measuring surfaces to the room. You assign
the desired luminaire type for the basic lighting.
When the lighting simulation is started, the room is calculated correctly in terms of
lighting technology.
A luminaire list provides clarity regarding which luminaires have been placed where in the
room. The photometric results can be checked in the 2D and 3D views and then output as
tables or false colours.
