The sun shines, making the ground lively. Sunlight is an important natural light source. It shines on the earth and makes the whole world colorful and colorful. The light we use in our daily life is an artificial light source, much weaker than sunlight, and the proportion of visible light contained is also different from sunlight. So, how do you feel the sun at night or indoors? The new technology developed by PaolodiTrapani of the University of isubria in Italy is artificial daylight. The prototype uses LED panels and diverges through transparent plastic panels. The main breakthrough of this technology is these titanium dioxide nanoparticles that are invisible to the naked eye but spread all over the panel! The main task of these particles is that the principle of scattered light is very similar to the fact that sunlight passes through the Earth's atmosphere. Some people may think this is unnecessary, but because the process simulates the scattering of Reylight in physics, it will make the light appear more real. In fact, the quality of natural light level helps to relieve mild depression and reduce stress. When it comes to problems, we don't always have access to it. Therefore, after the popularization of new technology, people can draw a bright spring behind their curtains, regardless of whether it is windy or rainy outside the house. Of course, there is always a process of popularization of technology. Although there are no related products for sale at present, diTrapani and his team have planned to sell them in the next few years through a company called CoeLux.
