Creating artificial sunlight to solve winter depression

The absence of the sun causes people who live in places where it does not shine and cannot see it for consecutive months to suffer lethargy and a constant state of depression, and there are closed workplaces that look like graves, like the basements of hospitals where diagnosticians and radiologists work, which have no windows First of all, affect their psychological state cannot be ignored. 

Light has always been used as a treatment for seasonal emotional disturbances and to ward off winter gloom, but the solutions ranged from several traditional and ineffective lamps, until Italian designer Paolo de Trapani decided to design an innovative and unique lamp under the shape of a window from which the light comes, so much so that the viewer thinks it is a real window through which the sun 

   When inventing CoeLux, Paolo wanted it to be on the wall or the ceiling of every closed and solid place where people could not see the sun, in order to make museums, metro stations, basements, gymnasiums , parking lots, healthcare facilities, nursing homes, basements and closed offices less dark than they 
Winter depression is something that we cannot underestimate, because Seasonal Affective Disorder is more common than you might imagine, especially in women, since it affects them much more than men, causing a state of lethargy, frustration, sleepiness all the time and craving.  for starchy and sugary foods, which makes them more frustrated due to weight gain, a feeling of constant heaviness and fatigue, avoidance of society, a tendency to withdraw from people, d a reluctance to work or the ability to study and collect. 

But the question is, how did the team of Italian designers achieve this degree of perfection that makes the lamp seem like a real window from which the sun comes?

The work was complex enough to consume the life of the designer and his team for ten full years of continuous work, to produce a simulation of this realism. The team worked on merging three elements to achieve this elaborate design that simulates reality, so they first made the sun out of LED lights with a special technology that made it look like light.  completely natural, then they created a complex optical system in which they used very precise nanomaterials to simulate the glow and the emission of rays from the sun, and then the blue sky background.

But it wasn't over yet. The team faced design challenges when it came to making what they designed more realistic and deep in three-dimensionality. So they developed the Maxwell light software they were relying on, adding scattering and polarization to its properties, as well as spectrometer measurements and data. With a virtual light spectrometer, a new interface has been added for users, from light experts to designers and physicists, to allow them to interact more easily.

The team also decided that their innovation would not be just a sun shining from the window, but rather programmed it on three views of three geographically different regions, so they programmed it on the sunshine of Northern Europe, where the sun's rays come from a low angle, as the CoeLux 30 system allowed the sunshine of the warm Scandinavian countries The CoeLux 60 system provided vertical sunshine for softer ambiance and more distinctive shade, while the CoeLux 45 system with twenty-five degrees of light was intended for Mediterranean dwellers who miss their homes. 

This unique innovation was selected among the 12 best innovations in Europe for the year 2014 by the European Commission at the Innovations Conference held in Brussels, and the European Union selected it among the projects it finances, and this innovation was launched in Venice, Italy. 

But the only problem with this wonderful innovation is its cost, as it costs $ 61,000, which equals 40,000 euros, and its installation costs another $ 7,000.
