In addition to the highly technical TC4-45 headlamp benchmark and the on-road “consumer report” benchmark available in previous releases, this version of LucidShape Lite includes the IIHS Headlight benchmark, which is based on U.S. Insurance Institute for Highway Safety (IIHS) guidelines.
The new benchmark allows you to analyze the performance of a beam pattern (.LID files) for low and high beams per the relevant IIHS rating and protocol content as of version 2 (November 2016). The IIHS benchmark includes:
- Illuminance-based visibility range testing on road
- Dosage-based glare test for oncoming traffic
- Overall rating results (good – poor)
The following figure shows a regular false color Bird’s Eye View generated in LucidShape Lite 2017.03-1 with a 5-lux illuminance isoline plot measured at a 25 cm above-road detection height. This was created using IIHS protocol-derived parameters to create the Bird’s Eye View from a low beam pattern and subsequently using the custom isoline functionality in the UVdataView’s properties.
