LightTools: What's New
LightTools 8.3 delivers new solutions for designing high-performance lighting systems with ease and efficiency.

Advanced Design Module

The LightTools Advanced Design Module provides a set of specialized tools to enable fast, robust modeling of reflective and refractive freeform optics in both single-surface and segmented configurations for a diverse set of illumination applications. The Advanced Design Module leverages proprietary algorithms from Synopsys’ LucidShape® products that automatically calculate and construct optical geometries based on user-defined illuminance and intensity patterns. This unique, functional approach gives you the freedom to focus on overall design objectives rather than the implementation details of complex optical components.

Key features include:

Freeform Designer for designing reflective and refractive surfaces that shape the resulting light pattern.
MacroFocal Reflector for designing segmented optics
Procedural Surface Lens for designing surfaces with pillowed optical arrays
LED Lens for creating various types of LED collimator lenses

User-Defined Volume Scattering (UDVS) API

The new UDVS API enables you to create custom volume scatterers using Windows COM technology, which can be dynamically linked to LightTools. It offers tremendous flexibility for defining custom scattering and phosphor interactions for LED packaging designs.

Volume Scatter Logger Utility

A new Volume Scatter Logger has been added to the LightTools Utility Library. The utility creates a log of scattering and phosphor conversion events to show what is happening in a scattering material, such as the amount of absorbed and lost energy, as well as shifts in wavelength.

Enhanced Unified Glare Rating Utility

The LightTools Unified Glare Rating Utility, which optimizes a luminaire’s glare rating when used in an indoor setting, has been enhanced to allow you to examine luminaire arrangements from the specification in plan view, create arrangements of luminaires by arraying source geometry, and create room geometry with defined ceiling, wall and reference plane reflectances.

Enhanced Street Lighting Utility

The LightTools Street Lighting Utility has been enhanced with new optimization metrics such as hemispherical, semi-cylindrical and vertical illuminance, built-in roadway classification specifications from the EN13201 standard, and additional
