Tech-Enhanced Light Mimics The Warmth And Movement Of The Sun Anywhere

CoeLux is a device that replicates daylight in any space.

Natural light or sunlight, being what it is, just really brings a unique warmth into a room. That is why large windows or skylights can change up a room dramatically.

Italy-based high-tech startup CoeLux has developed a device that lets people experience the sunlight wherever they are.

CoeLux is an optical system that is based on nano technology and replicates the natural light and the appearance of the sun and the sky. The system basically mimics daylight by artificially reproducing the color temperature of the sunlight and how the sun moves across the sky.

The optical system uses the latest LED technology to reproduce the sunlight spectrum, and the system creates a “sensation” of distance between the “sun” and the “sky.” The surface of the system is made of a few millimeters-thick nano-structured materials that recreate the scattering process that occurs in the atmosphere and makes the sky appear as the color blue.


CoeLux offers three types of settings for consumers. CoeLux 60 is for those people who “prefer the more dramatic slice of tropical light” and provides a bright, cooler sunlight with a high contrast of light and shadows. CoeLux 45 is for the “lovers of the Mediterranean basin” and provides consumers with a skylight that features an equal balance of light and shade. CoeLux 30 is designed for “enthusiasts of Nordic countries” and provides a 30 degree angle beam relative to the horizon. CoeLux 30 is meant to be a wall window and provides a warmer and more lateral light.

The CoeLux light system is well-suited for all types of indoor architectural spaces, including indoor spaces like malls, stores, fitness centers, hotels, subways, parking garages, and more. The system can be embedded into high-tech false ceilings and window systems to create a fake skylight in indoor or underground areas that the sun cannot reach.

CoeLux was developed by Italian physicist Paolo Di Trapani of the University of Insubria. The CoeLux light system is a research project funded by the European Union under the 7th Framework Program for research and development. The light system was selected as one of the 12 most technologically innovative projects in Europe by the European Commission and was presented at the 2014 Innovation Convention in Brussels, Belgium.
