LMT VELAS® GO-CL 6580

Precision and accuracy of VELAS® goniophotometer laboratories is on a par with all LMT® goniophotometers, last but not least due to the usage of class L photometry acc. to DIN 5032-6.

Vehicle goniometer for in-situ vehicle lighting assessement

  • Goniometer with light source rotation (turn-table) and moving photometer (acc. to CIE 070, IES LM-75)
  • Turn-table Ø=6.5m diameter for loads up to 3500 kg
  • Horizontal angle -180° ≤ H ≤ 180°, resolution 0.01°
  • Vertical angle coverage typically -7° ≤ V ≤ 6° typical (≙ 8m height), resolution 1 mm
  • Vehicle dimensions according to UNECE category M1 (length ≤ 7.0 m and width ≤ 2.0 m)
  • Test distance 25m
  • Tactile measurement system for determination of vehicle position on turn-table
  • Electric servo controls with absolute angular encoders (all axes software or manually controlled)

Photometric equipment

  • Class L photometer according to DIN 5032-7:2019
  • Imaging luminance measurement device (ILMD, type II acc. CIE 244:2021) for rapid capture of luminous intensity distributions

Test & measurement application

  • Test of vehicle lighting performance
  • Visual optical aiming assessement and check of automatic-levelling systems
  • Rating evaluation (CIE S 021, C-NCAP, HSPR, IIHS, etc.)
  • On-vehicle testing of automotive lighting regulations like UN R48/149, FMVSS 108 or related GB standards
  • Pre-series on-vehicle lighting check and performance benchmark

Software

  • LMT SoLiT VELAS for data-acquisition in vehicle-level laboratory assessment

Options

  • Dynamic laser system for individual screen projection of each headlamp cut-off
  • Monitoring system for periodic check of photometry and geometry
  • Camera system for determination of luminance centroid on headlamp outer surface
  • LMT SoLiT ACD (Aperture Centroid Detection)
  • LucidShapeLite for LMT (LSL4LMT)
