Synopsys upgrades illumination design software

Synopsys Inc. has unleashed the version 8.0 of its LightTools illumination design software that the company said offers multi-CPU support that dramatically improves the speed of lighting system simulations. With the addition of several 3D objects, application-specific utilities and enhancements to parametric controls, this version also provides features that simplify the design of modern lighting components, boasted Synopsys.

LightTools has been enhanced with a multi-threading capability that enables illumination simulation processes to take advantage of all CPUs or cores on a computer. The multi-CPU feature can dramatically improve the speed of simulations, analyses and design optimisations, said the firm.

To facilitate the creation of complex lighting components, LightTools introduced various 3D objects, including revolved sheets and solids, extruded sheets and solids and freeform sheets. These objects expand the range of shapes available for creating state-of-the-art illumination optics such as compact, freeform surfaces used in automotive headlights.

The LightTools Source Array Utility simplifies the construction of source arrays used for applications such as edge-lit displays and luminaires. It enables users to quickly and easily convert a given surface of a solid to an array of identical sources while requiring only a single source in the model.

It also promises to provide a specialised set of tools that guides users through the process of evaluating, designing and optimising luminance and illuminance patterns on roadways to meet industry-standard specifications. The utility has been enhanced to broaden capabilities for street lighting design. For example, users can now define a light distribution that is either Gaussian or uniform across a roadway in order to determine the type of distribution that is needed to meet roadway lighting specifications.

Improvements to LightTools' parametric controls include convenient new ways to move and group them. These enhancements help users more easily organise and manage elements that control the geometry, position and function of each component in a LightTools model.

Additional tools are available for visualizing the shape and orientation of a light source's illuminance distribution with respect to model geometry. This includes the ability to display true colour output in the LightTools 3D Design view, as well as the ability to concurrently display illuminance results for all surface receivers in a model, making it easier to compare results.

LightTools version 8.0 is available.
