Synopsys, Inc. (Mountain View, CA) introduces version 7.2 of its LightTools® illumination design and analysis software with features that will help users graphically analyze simulation results, compute important metrics when designing for the lighting industry, iteratively design with CAD software, and improve the efficiency of luminaire and solar designs.
The LightTools LumViewer, an interactive charting capability, has a new look and additional features to customize illumination simulation results to meet personal, company, or industry standards. Users can rotate and zoom 3D charts, change fonts and colors, view data on a logarithmic scale, and make many other customizations as needed. Users can also save charting customizations in a template to reload for later use, or to set as a default for all LightTools charts.
The LightTools simulation output now includes detailed beam statistics to provide lighting designers with access to beam and field width information for analysis and optimization. These statistics are useful for determining the angular or spatial spread of a beam pattern generated by an optical system, such as a luminaire. Designers can automatically optimize the optical system to match a specified beam spread.
With the new CAD file element, LightTools entities can be associated with an externally created CAD file, enabling users to update geometry with the click of a button without losing optical properties, names, or relations with other elements of the LightTools model. CATIA, IGES, SAT, and STEP formats are accepted. This capability simplifies the process of using CAD geometry in LightTools and ensures data integrity throughout design iterations.
3D compound parabolic concentrators (CPCs) and CPC reflectors are now available as native elements in LightTools. The CPC objects are useful in luminaire and solar design for collimating light from a source or concentrating light onto a receiver. The elements are fully optimizable; for example, users can automatically optimize a CPC’s size and angle to match a target illumination distribution, intensity, total power or flux on a receiver.
