During ISAL 2021 (Darmstadt, April 4-6, 2022), LMT® presented their new VELAS® goniophotometer product series for vehicle lighting laboratory assessment to the public.

While a simple setup of vehicle headlight centre beam analysis was shown at the LMT® booth, Thomas Reiners demonstrated in his oral lecture during the headlamp rating session, how the advanced product version is being used for measurement according to C-NCAP (ISAL 2021 – Proceedings p.374-382).

In contrast to traditional vehicle lighting assessment during night-time drives on test tracks, a VELAS® goniophotometer allows to measure vehicle lighting performance under laboratory conditions, without external influences from weather, road condition, background luminance, temperature, humidity and driving parameter.

Therefore, precision and accuracy of VELAS® goniophotometer laboratories is on eye-level with all LMT® goniophotometers, last but not least due to the usage of class L photometry as required by the C-NCAP Management Protocol. Additionally, camera-based goniophotometry offers high speed capture of luminous intensity distributions.
