MOUNTAIN VIEW, Calif., Aug. 2, 2011 — Synopsys Inc. has announced the availability of enhancements to its LightTools illumination design and analysis software, obtained as part of its acquisition of Optical Research Associates. LightTools 7.2 offers features that will help users graphically analyze simulation results, compute metrics and improve the efficiency of luminaire and solar products. These capabilities enable lighting designers to explore alternatives, study light behavior and improve product quality early in the process. The LightTools LumViewer, an interactive charting capability, has been enhanced with a new look and additional features to customize illumination simulation results to meet personal, company or industry standards. Users can rotate and zoom 3-D charts, change fonts and colors, view data on a logarithmic scale and make other customizations. They also can save charting customizations in a template to reload for later use or to set as a default for all LightTools charts. Computer-aided design (CAD) file elements enable iterative, seamless design with CAD software, and native compound parabolic concentrator objects improve the efficiency of luminaire and solar concentrator designs. The simulation output now includes detailed beam statistics to provide lighting designers 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 also 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 and without losing optical properties, names or relations with other elements of the LightTools model. CATIA, IGES, SAT and STEP formats are accepted. Three-dimensional compound parabolic concentrators (CPCs) and CPC reflectors are now available as native elements. The CPC objects are useful in luminaire and solar design for collimating light from a source or concentrating light onto a receiver. Users can automatically optimize a CPC’s size and angle to match a target illumination distribution, intensity, total power or flux on a receiver. LightTools is 3-D optical engineering and design software that supports virtual prototyping, simulation, optimization and photorealistic renderings of illumination applications.
