Would you like to brighten up your home with the warm tropical light or the bright colours of the northern sun?
Here is a solution that can turn almost any room into an environment where the sun always shines. A group of researchers from the University of Insubria (Italy) developed a lighting system designed to mimic sunlight propagated through the atmosphere—not just “a bright lamp,” but a more realistic sun-and-sky effect.
Create an environment where the sun always shines
To create a highly realistic effect, the researchers used LED technology, developing panels that mimic not only sunlight but also its reaction with the gases in the atmosphere. The goal is to recreate what our eyes expect outdoors: a bright “sun” and a sky tone that feels natural, even when you’re indoors.

CoeLux: an award-winning lighting system that mimics sunlight
The product we are talking about is named CoeLux and it won top spot as Light Source Innovation of the Year at the 2014 Lux Awards. In practice, it’s presented as a design-forward solution for spaces where natural light is limited—think interior rooms, basements, corridors, or workplaces with few windows.
How it works (in simple terms)
The panel uses white LEDs arranged behind a glass polymer coated with titanium dioxide nanoparticles. This setup makes it possible to reproduce the effect known as Rayleigh scattering, which helps create the classic division of colours many of us associate with an outdoor scene: a blue “sky” and a yellow “sun”.
| Component | What the article says it does | Why it matters for the “sunlight” effect |
|---|---|---|
| White LEDs | Provide the light source behind the panel | Creates the brightness needed for a convincing sun-like presence |
| Glass polymer | Houses and shapes the optical system | Helps manage how light is diffused and perceived |
| Titanium dioxide nanoparticles | Coating that enables Rayleigh scattering | Supports the blue-sky/yellow-sun colour separation many people find “natural” |
| Rayleigh scattering | The named phenomenon being recreated | Explains the familiar outdoor-like colour gradient (blue sky effect) |

Can it imitate different weather?
However, if you are fond of unpredictable and frequent weather changes, you can set the LED so as to imitate any weather. In other words, the system is described as adjustable—so you’re not locked into a single “always-summer” look if you prefer a different atmosphere.

Where an LED “sunlight panel” can make a difference
Designed as a design element, the panel can be used in various ways:
- To revalue properties and apartments with low light (for example, interior rooms or spaces that don’t get much daylight).
- To enhance the mood of the people by creating a brighter, more “open” feeling indoors.
- To improve the climate of the workplace, especially in areas that rely heavily on artificial lighting.
Isn’t it beautiful?
