Exporting a Speos Light Box

This page shows how to export a Speos Light Box. Exporting a light box enables you to safely exchange data.

To export a Speos Light Box:

From the Light Simulation tab, click Light Box > Export Speos Light Box .
Rename the Speos Light Box.
If you want to set an Axis System (different from the axis system of the assembly), click one point for the origin point and two lines for X and Y directions or click and select a coordinate system to autofill the Axis System.

Setting an axis system is optional but ensures that the exported component keeps the right orientation and origin point. If the axis system is kept empty, the reference is the origin of the main assembly.

Note: If you define manually one axis only, the other axis is automatically (and randomly) calculated by Speos in the 3D view. However, the other axis in the Definition panel may not correspond to the axis in the 3D view. Please refer to the axis in the 3D view.
In the 3D view click to select the source(s) you want to include in the export.
Note: You cannot select a source included in a Speos Light Box Import.

Your selection appears in the Sources list.
In the 3D view click to select the geometries you want to include in the export.

Make sure a material is applied on all surface bodies that you want to include in a Speos Light Box Export.

Note: You cannot select a geometry included in a Speos Light Box Import.

Your selection appears in the Geometries list. Optical Properties (VOP, SOP, FOP) related to the selected geometries are included in the export.

Tip: You can select elements from the 3D view or directly from the tree. To deselect an element, click back on it.
To edit the Meshing of the exported geometries, right-click the light box from the Simulation panel and click Options.
Set the Fast Transmission Gathering to True if you want to neglect the light transmission with transparent surfaces.

Note: FTG does not apply to a 3D Texture, Polarization Plate and Speos Light Box Import.
If you want to protect the light box, set Password activated to True.
To define the password:
Warning: In version prior to 2023 R1, passwords were not hidden. As soon as you open a project containing passwords, they are hidden and you cannot retrieve them. Make sure to save your passwords in a safe place before opening your project in 2023 R1 or subsequent versions.
- Enter a custom password manually.
  The password is directly hidden. Make sure to save it in a safe place as you will not be able to retrieve it from Speos afterwards.
- Click in the Password field and click Generate Password to automatically generate a strong password.
  A prompt message appears to warn you that the password is directly hidden and copied into your clipboard. Click OK and make sure to save it in a safe place as you will not be able to retrieve it from Speos afterwards.
If you want to restrict the access to all the sources/geometries/optical properties details of the Speos Light Box and protect the intellectual property, check Black box.

The Speos Light Box is now created. A *.SPEOSLightBox file is exported in a subfolder located in SPEOS output files directory. The file dependencies are included in the *.SPEOSLightBox file.

Tip: To include modifications done after the export, right-click the Speos Light Box export and click Compute

to regenerate the light box.
