Light Tec is happy to inform you about LightTools version 8.5 !

Key new features in LightTools 8.5 include the following, which will be described in more detail in the release notes:

Conformal Surface Receivers
LightTools surface receivers can now be placed on both planar and non-planar surfaces. Because of this new conformal capability, you can now place receivers on most surface types to collect illuminance data, using one of four mesh mapping types:

  • XY mapping for planar surfaces and lens surfaces
  • Cylindrical mapping for cylinders and cones
  • Spherical mapping for spheres
  • UV mapping for all other surface types

You can vary the number of bins in the mesh, and use the same filtering, analysis, and optimization capabilities that exist for planar meshes.

Expanded Visualization of Illuminance Results in the 3D Design View
LightTools provides a capability for displaying a raster image of illuminance output so that you can visualize the  orientation and distribution of the illuminance data relative to model geometry. In previous releases, this capability  was provided only for receivers on dummy planes. In this release, because of this capability is extended to most surfaces  in LightTools. In addition, the appearance of the illuminance data can now be controlled by the settings in the LumViewer  for color scheme, scaling, contours and mesh lines, smoothing and lit effects, and linear and logarithmic settings.

New Parameter Sensitivity Analyzer
This utility has been substantially enhanced with a new user interface and functional improvements that include:

  • Configuration support allowing you to analyze a parameter across multiple configurations
  • Parameter lists and wild card selection
  • Ability to run scripts after variable values are changed (but before evaluation) or after each evaluation cycle is complete
  • Updated charting, including multiple chart views
  • 2D chart now displayed directly in the analyzer
  • GIF generation capability for graphics

Improvements to the Utility Library

– Light Guide Designer
Enhancements to this utility include:

  • Additional, integrated, non-circular profile shapes
  • Bezier scaling of profiles along the length
  • User H,V target grid for centroid pointing direction targets
  • Use of light guide surface as the receiver (with light guide receiver filter)
  • Easy change of receiver/texture bounds at the ends of the light guide
  • Non-uniform spatial targets will be easier to use, can be set using bin areas, user Bezier curve, or user values

– Street Light Utility
Enhancements to this utility include:

  • Capability for defining IES Type sources, which can be specified using the Longitudinal and IES Classifications types (e.g., Medium II) or by manually setting the related parameters (e.g., Peak Intensity Location, Half Intensity Locus Radius, etc.)
  • Charting has been added to illustrate the source settings
  • IES sources can be used by the Freeform Designer to create the corresponding freeform lens that creates the specified light pattern

– Source Array Utility
You can now use the Source Array utility to create radial or rectangular geometry. In previous releases, the only option was rectangular.
