DIALux

DIALux is a 3D graphics software for lighting design developed by DIAL GmbH in Lüdenscheid. It is mainly used by lighting planners, consultants, architects, lighting technicians and electricians to plan, calculate and visualize light for indoor and outdoor areas. The software is freely available through the manufacturer's website and 
this video tutorial offers a quick overview. 
A survey by Linköping University on the use of lighting simulation tools in Sweden found that over 70% of respondents identified DIALux as their primary tool for lighting simulations.
Many lamp and luminaire manufacturers offer plug-ins that integrate the beam characteristics of their products into the DIALux platform. As a result, more than 2 million luminaires are currently available for planning. 
DIALux includes features for photometric calculations and supports the planning and simulation of various environments, including rooms, multi-story buildings, pathways, parking lots, streets, and landscapes. 
It also offers functionality for daylight simulation, obtrusive light calculations, the lighting design for sports venues and emergency lighting planning according to the DIN EN 1838 standard. Recent versions also enable energy assessments based on DIN V 18599 and EN 15193 standards, which are required for energy performance certificates.
3D models created with DIALux can be rendered with the raytracer POV-Ray.
==History==
DIAL was founded in 1989 as German Institute for Applied Lighting Technology. Since then, the company has been involved in software development, lighting technology, lighting design and building automation. DIAL has additional locations in Italy, the US, and Taiwan.
The first version of DIALux was released in 1994. 
The program was further developed over the next few years and many new functions were added until version DIALux 4.1 was finally created.
DIALux evo was announced as the successor and released for use in 2012.
The DIALux evo version that was then released is based on a completely new graphics engine, a new interface and new functions.
As many designers were still very used to the previous version of the program, it could still be downloaded from the company's website for a while to make the transition from DIALux 4 to DIALux evo easier. 
DIALux evo has now established itself and has many more functions than the previous version. The latest version is available in 26 languages ​​and has more than four hundred luminaire manufacturers in its database.
DIAL has completed joint research projects with the Fraunhofer Institute for Building Physics (IBP). The findings aim to enhance the energy-saving potential of lighting projects through the software.
==Notable uses==
The possible uses of DIALux evo are diverse and not limited to specific applications. 
The software has been applied in projects like the lighting design for the Alte Pinakothek in Munich and the UNESCO World Heritage Site Imperial Palace of Goslar (Kaiserpfalz Goslar).
DIALux has been used in case studies, such as an aircraft cabin lighting design, optimizing the lighting of the Jamkaran Mosque, for simulating lighting scenarios in historical gardens to evaluate light interactions with the surroundings or in analysing and modeling the visual perception of exhibition rooms of the Abdürrahim Tuncak Atatürk House Museum.
The program was also applied to specific tasks like optimizing the lighting of artworks in galleries or as a simulation tool in studies on the design of LED tunnel lighting for motorway tunnels.
The Project Showroom in the DIALux Community shows further real projects and application possibilities.
