Synopsys launched version 7.3 of their LightTools illumination design and analysis software. LightTools 7.3 includes software enhancements to help designers jumpstart, analyze, optimize and manage illumination designs. The tool includes a variety of new illumination design features in areas such as application-specific design, color quality analysis, LED phosphor modeling, and design management and performance. LightTools v7.3 is available now.
LightTools is a 3D optical engineering and design software product that supports virtual prototyping, simulation, optimization and photorealistic renderings of illumination applications. LightTools v7.3 has been enhanced to accelerate operations, especially for large models, and includes 64-bit support that effectively eliminates model size limitations.
The updated tool includes a utility for designing and optimizing roadway lighting systems. The LightTools Street Lighting Utility provides a specialized set of tools that guide users through the process of evaluating, designing and optimizing luminance and illuminance patterns on roadways to meet industry-standard specifications. Key capabilities include:
- Models complex luminaire designs directly in a roadway lighting configuration
- Supports automatic design optimization to help ensure that the design meets industry standards
- Performs fast calculations of perceived light levels on a street for a series of fixtures
- Calculates luminance data based on standard observer positions
- Displays pass/fail criteria for the design based on industry standards
LightTools now supports two additional metrics for evaluating a light source’s color rendering performance: Color Quality Scale (CQS) and Gamut Area Index (GAI). These metrics are particularly useful for measuring the color quality of LED sources, and they augment the lighting industry’s primary tool, Color Rendering Index (CRI), for evaluating a light source’s saturation and contrast. Both CQS and GAI provide a highly accurate evaluation of light quality for color-critical applications, such as in retail environments.
LightTools v7.3 also includes enhanced LED phosphor modeling, which streamlines phosphor material manufacturing for solid-state lighting applications. LightTools provides the flexibility to specify phosphor mixture ratios as a percentage by volume or weight. During manufacturing, this simplifies the process of determining phosphor particle concentration and relating model parameters to laboratory procedures.
In addition, the tool simplifies and speeds design management with a centralized optical property manager. The LightTools Optical Property Manager helps designers more efficiently manage their design data. It provides a central location for assigning and changing optical properties throughout a model, as well as for defining defaults applied to new objects. An optical property in the master list controls all the areas in the model to which it is applied, so it is easy to make global changes at one time.
