LightTools 7.3 RC Available Now
We are pleased to announce that LightTools 7.3 Release Candidate (RC) is available for download. With this release, LightTools is available as a 64-bit application as well as a 32-bit application. The 64-bit version provides full access to available memory, enhancing program performance for large model manipulation and computations.
LightTools 7.3 RC is an early version of LightTools 7.3 that we are making available to LightTools users who would like to use its new capabilities now. The LightTools 7.3 RC version has already undergone extensive testing, and we feel that quality of this software is high. If you encounter any problems in this version, we encourage you to notify us. We will address critical issues before we ship the final LightTools 7.3 later this year. LightTools 7.3 RC is available only by download from the links provided below.
LightTools 7.3 RC License Files
Your LightTools 7.2.0 license file is valid to use for LightTools 7.3 RC. If you do not have a LightTools 7.2.0 license file, you can obtain one from the Synopsys SolvNet site: https://solvnet.synopsys.com. For complete details about how to download a LightTools license file from SolvNet, please see Obtaining CODE V and LightTools Software and License Keys.
Key Features in LightTools 7.3 RC
A description for each key feature is provided below, along with a link to a short video that shows how it works.
The Street Lighting Utility provides fast calculations of street illuminance and luminance levels for standard observer positions for fixtures designed in LightTools or defined in IES files. The utility supports automatic design optimization to meet industry standards, including surround ratio and average luminance.
The Optical Property Manager simplifies and speeds the process of managing your model’s optical properties. It provides a central location for assigning and changing data, as well as for defining defaults.
Charting has new features that improve the quality of analysis output used to evaluate and present simulation results. Improvements include additional data types for Cartesian 2D, polar surface, intensity slice, and true color charts.
Phosphor modeling enhancements provide flexibility to specify mixture ratios as a percentage by volume or weight. This simplifies the process of determining particle concentration and relating model parameters to laboratory procedures.
The Test Point Analyzer Utility has been redesigned and expanded. This utility supports the evaluation of automotive forward and rear lighting with respect to standards based on intensity test point metrics. Improvements include an updated user interface, support for IES files (Types A, B, or C, and LDT), and the inclusion of test areas in addition to points and zones.
The Solar Source Utility is new in this release. This utility positions and calibrates models of the sun and solar tracking elements. Its setup data is stored in the LightTools model, allowing you to take advantage of the Parameter Sensitivity Utility to vary the time of day and update the source while recording other items, such as power on a receiver.
Improvements for modeling measured BSDF scattering include updates to the library of measured BSDF materials, direct access to the library from the Optical Properties Manager, and simplified steps for setting up and modifying BSDF scatterers, whether you use the BSDF library or your own measured BSDF data.
Color analysis enhancements include two new color measuring metrics: Color Quality Scale (CQS) and Gamut Area Index (GAI). These metrics are particularly useful for measuring the color quality of LED sources.
