Artificial Illumination Device For Generating Natural Light

Patent No. EP2920511 (titled "Artificial Illumination Device For Generating Natural Light") was filed by Coelux on Nov 14, 2012. The application was issued on Oct 11, 2023.

Patent Summary

An artificial illumination device that mimics the appearance and effects of natural light from the sun and sky. The device aims to provide a realistic simulation of daylight indoors by illuminating spaces like the sun and sky do, while also having an appearance when viewed directly that matches the infinite depth and distance of natural light sources. The device achieves this through a collimating lens, a diffused light generator, and a reflective box. The collimating lens focuses primary light into a small, bright spot representing the sun. The diffused light generator creates a uniform, diffuse background like the sky. The reflective box reflects light back to mimic the aerial perspective. The collimator, diffuser, and reflector are positioned and angled to avoid conflicts between perceived depths and cues. This provides a realistic indoor daylight experience without visual conflicts when viewed directly.
