In dystopian films, it is a common trope to depict the sky as filled with a thick fog, blocking the sun's rays and bringing a dark atmosphere to the scenes. Whether in Blade Runner or in a Black Mirror episode, the lack of sun commonly represents a future we would rather not live in. The sun provides heat to planet Earth and is a great source of light energy, essential for the survival of many living creatures. We can generate electricity from the sun and still use only a fraction of the energy it provides. Sunlight also regulates our circadian cycle, which affects our mood. But recent forest fires and industrial pollution in some large cities have already made the dystopian blockage of sun a relatively common phenomenon, depriving hours of sunshine from many inhabitants. Concurrently, with the COVID-19 pandemic, we are living a plot that few science fiction writers could have predicted, and new technologies and solutions have emerged to try to contain the spread of this invisible enemy. Can the sun, or specifically ultraviolet radiation, kill viruses and bacteria? Could it kill the coronavirus?
Artificial Lighting: The Latest Architecture and News
Of the varying aspects of architectural and interior design, lighting is one element that can visually enhance or destroy a space. This influence stems from the wide range of artificial lighting designed for the most widely differing tasks, environments, and purposes, including internal and even external spaces such as facades and landscape projects. Think of two environments with the same dimensions and layout. Suppose that in the first, only one point of light was applied - a general, unspecified point of light in this case - while in the second a light project was performed considering the use of space and valuing certain aspects of the architectural design. Undoubtedly, the second option is a more pleasant space. In the same way, poor lighting design can ruin an environment. But how is it possible to achieve these different results?
In a previous article, we already showed how to calculate the correct light intensity required for each environment. Here, we compile a list of some of the key types of lighting systems.
