LMT VELAS® LITE

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.

In-situ vehicle lighting assessement

  • Screen-goniophotometer with fixed light source (acc. to CIE S027)
  • Vehicle dimensions according to UNECE category M1
  • Vertical angle coverage -2.5° ≤ V ≤ 4° (typical (*))
  • Horizontal angle -15° ≤ H ≤ 15° (typical (*))
  • Test distance 15m (typical (*))
  • Tactile measurement system for determination of vehicle position on turn-table

(*) based on individual laboratory dimensions

The system can be operated stand-alone or may be integrated into an existing LMT GO-H goniophotometer laboratory.

Photometric equipment

  • 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 and rating evaluation
  • Visual optical aiming assessement and check of automatic-levelling systems
  • 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)
