RELUX is an independent, family-owned company from Switzerland specializing in the development of lighting design software in a BIM (Building Information Modeling) environment. The company's flagship solution is Relux – a free, professional tool for the design, simulation, and visualization of architectural lighting, both artificial and natural. The program is widely used by engineers, architects, and interior designers worldwide.
The software enables precise photometric calculations, analysis of design compliance with applicable standards, daylight simulations, and the creation of realistic 3D visualizations of designed spaces. Users also have access to extensive databases of lighting products equipped with real photometric files, allowing for a faithful representation of designed installations.
RELUX also develops a range of services supporting the digitalization of the design process. These include, among others, Collecting product data, creating digital twins of luminaires and devices, utilizing AI technology for process simulation and planning, and providing analytical tools to support tenders, purchasing, and product lifecycle management. As part of these activities, the company also obtains information on the installation, maintenance, and disassembly of lighting fixtures.
Thanks to its compatibility with CAD systems and BIM technology, Relux is a comprehensive tool supporting the design of modern and efficient lighting installations. The basic version of the program is available free of charge.
Lena Lighting has become an official partner of RELUX Software – one of the leading lighting design tools in the BIM environment. Thanks to this partnership, designers and architects gain direct access to photometric data and digital luminaire models, which significantly speeds up the design process and improves the accuracy of lighting simulations.
