MOUNTAIN VIEW, Calif., Dec. 3, 2010 — Available from Synopsys Inc. as part of its acquisition of Optical Research Associates, is LightTools Version 7.1 illumination design and analysis software. The latest version delivers new analytical capabilities that speed the development of luminaires, particularly for general lighting and automotive applications. A new user interface features a maximized working area and flexibility to help boost designers’ productivity throughout the design and verification process.
Highlights of the new release include additional photometry type support for far-field and surface receivers; standard photometric report generation; illuminance data display in the 3-D model for fast visualization of results; and CIE color difference analysis for calculating and optimizing system color performance.
The software assists designers in visualizing and optimizing luminaire performance and helps accelerate the process of validating a system’s color quality, light distribution and other key performance metrics.
It adds support for IES photometry types A and B for orienting intensity data for both far-field and surface receivers. This simplifies the analysis of sources with nonrotationally symmetric output, such as automotive headlights, taillights and interior lighting. In addition, LightTools 7.1 contains a utility for automatically generating photometric reports in the standardized IES format; IES Indoor, Flood and Road Report types are all supported.
A new analysis feature lets operators superimpose illuminance data on any user-defined plane in the 3-D model, helping them quickly understand the shape and orientation of the distribution across a receiver relative to the model geometry.
A new CIE color difference capability provides a mechanism for calculating and optimizing spatial or angular color differences in a system. This analysis is useful for designers whose goal is to produce an even color distribution across an entire display, for applications ranging from flat panel displays and projectors to display backlights and LED-based luminaires.
Improvements to the user interface provide new ways to organize and maximize desktop workspace. Specifically, 3-D design views and analysis charts are now presented in tabbed or floating windows, giving users the flexibility to make a 3-D view as large as desired while still having rapid access to other windows via tabs. Dialog boxes, such as Properties and Preferences, can be moved outside the LightTools window to a second monitor, if available.
