01What is being requested
This document is a doctoral thesis on simulating luminance distributions of luminaires from ray files for accurate optical simulations.
The assignment consists of the supply of luminaires for the Vathorst district in Amersfoort. The quantities to be supplied, totaling 2,765 units, are divided into 583 units in RAL 9006 and 2,182 units in RAL 9005.

02Strategic insight
Strategic insight · AI analysis
When performing optical simulations, focus on the accuracy of the input data, such as geometry and light sources. Take into account the influence of material properties on the final luminance distribution. Where possible, use geometric modelling in combination with ray file sampling for efficient calculation.
03Points of attention
Important · 4
Current ray-tracing software cannot directly simulate luminance distributions when the light source is modelled as a ray file.Important
The brute-force method for simulation requires very large amounts of computing power and time.Important
The BSDF of materials has a significant influence on the luminance distributions of the complete lighting fixture.Important
Variations in BSDF measurements can be caused by the measurement setup itself.Important
04Exclusion grounds
Exclusion grounds — consult the ESPD
- No specific exclusion grounds were extracted. In a European tender, the mandatory and discretionary grounds of art. 2.86/2.87 of the Dutch Procurement Act almost always apply — check the European Single Procurement Document (ESPD).
