Speos Light Box Overview

The Speos Light box allows you to export and import geometries along with the associated optical data (sources, Optical Properties, meshing properties).

The Speos Light Box can be used for data exchange between suppliers and customers. It is compatible with multi-CAD platform where Ansys software are integrated.

  • The Light Box is encrypted and only Speos can read it.
  • The Light Box can also be protected with a password to reinforce security. Other users will not be able to use the Light Box without the password.
  • The Light Box can be black-boxed to restrict the access to all the sources/geometries/optical properties details and protect the intellectual property. Other users will not be able to access the Light Box content and how light propagates inside it.

In Speos, you can:

  • Export a Speos Light Box file,
  • Import a Speos Light Box file,

  • Re-import an exported Speos Light Box file.

    Note: Ansys software can only read and use data from a Speos Light Box. Nothing can be modified from a Speos Light Box.

What does a Speos Light Box contain?

Geometries

Compatible geometries along with associated optical and meshing properties.

All geometries integrated to the Speos Light Box are stored as mesh (with meshing properties related to the Speos properties).

CAUTION: You cannot add faceted geometries from the 3D view into a Speos Light Box. Add them from the Structure tree.

Sources

In the Sources list, from the specification tree or 3D view, you can click the sources to add to the exported component.

You can add the following sources:
  • Source group
  • Surface source
  • Ray file source
  • Display source
  • Light Field source
  • Sources coming from imported Speos Light Boxes.
Note: Speos Light Box Export does not support Speos Patterns.
Note: The Length of rays of a source is not taken into account in a Speos Light Box. After the Speos Light Box import, the length will be different from the length set in the original source.

Files

A Speos Light Box can include the following file types:
  • *.scattering (advanced scattering files)
  • *.simplescattering (simple scattering files)
  • *.brdf (complete scattering files)
  • *.unpolished (unpolished files)
  • *.BSDF180 (BSDF180 files)
  • *.anisoptropicbsdf (anisotropic bsdf files)
  • .material (material files)
  • *.ies (IES files)
  • *.ldt (Eulumdat files)
  • *.spectrum (Spectrum file)
Note: All other file types not included in the list above are not encapsulated in the Speos Light Boxes. However they are physically located next to the file as dependency files.
