Exporting Intensity Results in .ies or .ldt Format

When editing an intensity type XMP map, you can export the intensity results in the IESNA or Eulumdat formats according to the Ansys Intensity Type you defined in Speos.

  1. In File, click Export.
  2. In Save as, select .ies or .ldt.

    For more details about the IESNA format, see Standard File Format for Electronic Transfer of Photometric Data and Related Information. Speos does not support the version LM-63-19. Speos only supports LM-63-02 and previous ones (86, 91,95).

    For more details about the Eulumdat format, see Eulumdat File Format Specifications.

    Horizontal flip option is not taken into account during IES or EULUMDAT exports.

Export format: IESNA LM-63 type A
  • Orientation: X as meridian, Y as parallel.
  • Alignment: polar axis along the positive Y axis and H0 axis along the positive Z axis.
  • Sampling: same sampling as the intensity sensor.
  • Validity area: -90° < x < 90° horizontal and vertical.

    Everything out of the validity area according to the original XMP map is not generated in the .ies file.

Export format: IESNA LM-63 type B
  • Orientation: X as parallel, Y as meridian
  • Alignment: polar axis along the positive X axis and H0 axis along the positive Z axis.
  • Sampling: same sampling as the intensity sensor.
  • Validity area: -90° < x < 90° horizontal and vertical

    Everything out of the validity area according to the original XMP map is not generated in the .ies file.

Export format: IESNA LM-63 type C
  • Orientation: Conoscopic.
  • Alignment: polar axis along the positive Z axis and H0 axis along the negative X axis.
  • Sampling: same sampling as the intensity sensor for theta, and fixed to 361 (1°) for phi.
  • Validity area: -90° < x < 90° on theta, 0°< x < 360° on phi.
Export format: Eulumdat
  • Orientation: Conoscopic.
  • Alignment: polar axis along the positive Z axis and H0 axis along the positive X axis.
  • Sampling: same sampling as the intensity sensor for theta, and fixed to 361 (1°) for phi.
  • Validity area: -90° < x < 90° on theta, 0°< x < 360° on phi.
