Regulations in Virtual Photometric Lab

Virtual Photometric Lab allows you to compare non-conoscopic intensity maps to regulations of the lighting industry and car supplier specifications thanks to a set of different tools.

The regulations are very strict in the lighting industry and you must compare your results to the regulations and car supplier (OEM) specifications to validate them.

In this way, Virtual Photometric Lab allows you to create your set of measures on specific areas in order to tests if the non-conoscopic intensity results (SAEA or SAEB) pass the regulations and the OEM specifications. You can then set up a report of the result analysis according to the regulation.

Useful Regulation Tools

Virtual Photometric Lab provides you with different tools to analyze your results in comparison to the regulations and specifications.

Measures Tool

The Measures tool provides you with a full view of the measurements and area of a regulation and allows you to apply your own measurements and specifications to see if they fail or pass. The color code lets you quickly identify the measures that pass or fail.

Note: Each regulation is included into the Optics Library (downloadable on the Ansys Portal) and corresponds to a *.xml template containing the different regulation information. This way you can directly add up the *.xml template to the Intensity sensor in Speos.


Measurement Grid View

The Measurement grid view provides you with a spatial representation of the area measurements and their results. The color code helps you see if the measures fail or pass.



Regulation Report

The Regulation Report provides you with an overview of the result analysis in comparison to the regulation.

The Regulation Report allows you to adjust which element of the report to display.



Generic Workflow

  1. Make sure you downloaded the *.xml file containing the regulation you want to assess.

    Regulations are included in the Optics Library that you can download on the Ansys Portal.

  2. In Speos, create your optical system.
  3. Create an Intensity sensor:

    • Define the intensity sensor as non-conoscopic (SAEA or SAEB).

      Or

    • Directly import the *.xml template containing the regulation.

      This will define the intensity sensor according to the template information.

      We recommend you to set Dimension from file to True so that the size of the Intensity sensor matches the size of the sensor used to define the regulation.

  4. Run a simulation containing the optical system.
  5. Open the *.xmp result file which is a non-conoscopic intensity map.

  6. Open the Measures tool.

    You can directly see what measures pass or fail the regulation.

  7. If you want, you can add OEM specifications and see if they pass or fail.

    Tip: if you want to keep the OEM specifications, you can export a template. It will then include the regulations and the specifications information.

  8. Open the Measurement Grid View.

    The Measurement grid view provides you with a visual representation of the repartition of your measures on the map.

  9. In the main Virtual Photometric Lab window, manage the different elements to add in the report.

    They provide you with an overview of the XMP map in comparison to the regulation and OEM specifications.

  10. Iterate until you have what you expect: modify your optical system in speos, run the simulation and analyze the result in Virtual Photometric Lab.
