Dial and Relux team up to create uniform design format

LIGHTING DESIGN software rivals Dial and Relux are jointly planning to develop an open data format for luminaires and sensors, Lux can reveal.

The new format can be used, among other things, in the companies' two lighting design programs, DIALux and Relux.

It’s understood that the move has been spurred by the growth in shared project  planning methods, such as Building Information Modelling (BIM), which require data to be processed uniformly.

The two companies want to meet these challenges with an open data format for import and further processing purposes.

In comparison to the frequently-used IES and LDT formats, the data format will contain more comprehensive information about the product. This can be in the form of parameters such as geometry, photometry, texts, product images, dynamic control and controllability.

The open data format has many benefits for lighting designers and manufacturers alike. Manufacturers who are actively involved in the development process need only provide one format for the two lighting design programs DIALux and Relux. This improves the data quality available on the market and makes it more up-to-date.

In addition, products can be simulated even more realistically in the planning process.

‘DIALux is a powerful and open product with an open data format. With DIALux we want to make life easier for planners and manufacturers’, said Dial chief Dieter Polle.

‘The aim is to standardise the creation of product data and continually adapt it to requirements in order to ensure smooth processing of high quality’, says Markus Hegi, CEO of Relux.

The cooperation partners will start work this year and report together on the current status of the cooperation.
